Shopping for a vacuum can feel like wading through an endless catalog of lookalike machines, each promising “powerful suction” and “lightweight convenience.” The truth is, only a few models actually earn long-term loyalty. Two that consistently show up in conversations—and still sell well years after release—are the Shark NV501 Rotator Lift-Away and the Shark NV352 Navigator Lift-Away. Both are upright vacuums with Shark’s signature Lift-Away canister design and sealed HEPA filtration, and both deliver the kind of no-nonsense cleaning power that made Shark a household name. But once you start comparing them, subtle differences in weight, design, noise, and included tools begin to matter. I’ve lived with both, used them in messy, pet-filled spaces, and put them through real household challenges. This review breaks down how the two stack up in every meaningful category so you can decide which upright actually fits your cleaning style.

Design & Build Quality
When comparing upright vacuums, one of the first things you notice before even plugging them in is how they are built. Weight, material finish, balance, and small design touches all affect whether a vacuum feels like a tool you’ll happily use every week or a chore you want to avoid. The Shark NV501 and NV352 are both “classic” Sharks in that they are bagless, upright, and feature Shark’s Lift-Away system that allows you to detach the canister for above-floor cleaning. But there are clear distinctions in how each model approaches design. Let’s break them down in detail.
Overall aesthetic and finish
The NV501 comes from the Rotator line, Shark’s more premium family. It has a glossy finish, crisp lines, and styling cues that make it look like a higher-end appliance. It often comes in a white-and-red or metallic scheme, giving it a more modern, eye-catching presence. By contrast, the NV352 belongs to the Navigator line, which has always leaned toward utility and lightness over flash. Its color palette is more subdued—often lavender or light gray—and the plastics feel thinner and less luxurious. Neither one looks cheap, but you can immediately tell the NV501 is designed to project refinement while the NV352 leans on simplicity.
Materials and durability
Both vacuums use mostly ABS plastics with some rubberized touches in key areas like the wheels and seals. The NV501’s plastics feel thicker in hand, particularly around the nozzle and canister latches. This doesn’t mean the NV352 is fragile, but it does communicate its lightweight mission: less plastic means less weight, which pays dividends when carrying it upstairs. The NV501 seems like it could handle more accidental bumps into furniture without showing scuffs, while the NV352 benefits from being lighter, so it doesn’t hit as hard in the first place.
Weight and balance
One of the biggest differences between the two is weight. The NV352 weighs about 12.5 pounds, while the NV501 tips the scale closer to 15.5 pounds. Three pounds may not sound like much on paper, but in practice it’s a real distinction. You feel it when hauling the machine upstairs, when pivoting around furniture, and when lifting the canister off in Lift-Away mode. The NV352 feels nimble and almost sprightly, encouraging quick cleanups. The NV501 feels more substantial, almost planted, and that extra heft translates into a vacuum head that stays more firmly pressed against carpet fibers during use. The choice becomes a tradeoff: lighter weight for maneuverability or heavier weight for a sturdier, more anchored feel.
Nozzle and cleaning head design
The nozzle design tells you a lot about Shark’s intentions for each vacuum. The NV501’s nozzle is wider, with a low front edge and integrated LED headlights. These headlights, while often dismissed as a gimmick, actually make a real difference in dim areas like under couches, in hallways, or during nighttime cleaning. They highlight dust and crumbs you might otherwise miss. The NV352’s nozzle is simpler: no lights, slightly narrower, and with less decorative shaping. Both use a similar brushroll setup, but the NV501’s extra width means fewer passes in wide rooms, while the NV352’s slimmer head can snake between tighter furniture legs.
Lift-Away canister construction
Both vacuums share the Lift-Away system, which is essentially a removable pod that detaches from the upright frame. This lets you carry the canister and use the hose with tools to clean stairs, shelves, drapes, and upholstery. The NV501’s pod feels more premium: the release latch is firmer, the handle more ergonomic, and the balance when carried is slightly better. The NV352’s pod is lighter, which makes it easier to hold for extended periods but also gives the impression of being more “plastic.” Functionally they are nearly identical, but if you hold both side by side, the NV501 feels like a step up in refinement.
Stability and tip-over resistance
One underrated aspect of design is how stable a vacuum feels when you’re using hose tools. Some uprights tip over easily the moment you tug on the hose. The NV501, with its heavier base and broader stance, is noticeably more stable. You can extend the hose for a quick ceiling corner dusting without worrying that the unit will crash onto the floor. The NV352, while not especially tippy compared to other light vacuums, is easier to knock over if you tug too hard. This is the tradeoff of having a lighter, narrower body. If you do a lot of above-floor cleaning without detaching the pod, the NV501 gives you more confidence.
Cord management and reach
Both machines use a 25-foot cord, which is middle-of-the-road for uprights. The difference comes down to cord storage and handling. The NV501 has cord hooks placed higher and slightly more forward, which makes winding and unwinding a little smoother. The NV352’s hooks are placed in a more traditional, utilitarian way. Neither cord retracts automatically—you’ll be looping manually either way—but the NV501’s slightly more refined placement keeps the cord from tangling with tools as easily.
Dust cup design and usability
Dust cup capacity is another area of subtle difference. The NV352’s dust cup holds roughly 1.1 to 1.2 quarts to the fill line, while the NV501 is closer to 0.88 quarts. That means the NV352 technically lets you vacuum a bit longer before needing to empty it. However, the NV501’s cup has a sleeker release system and a slightly more solid feel when clicking back into place. Both cups empty from the bottom, which reduces mess compared to top-emptying designs. Over time, either cup will develop a fine coating of dust that needs to be rinsed; both are removable and washable.
Filtration and seals
In terms of filtration, both have sealed systems with HEPA filters, which is a big deal for allergy sufferers. What changes is the presentation: the NV501 advertises Shark’s “Anti-Allergen Complete Seal” more prominently, reinforcing its premium positioning. The NV352 has the same sealing principle but markets it less loudly. Functionally they both work the same way: dust and allergens are trapped inside and kept from leaking back into the air. Build quality here matters because poor seals can lead to fine dust escaping at seams. The NV501’s thicker plastic and firmer locking tabs give a bit more confidence that seals will stay tight over years of use, though the NV352 has proven reliable in practice as well.
Ergonomic design elements
The NV501 has a slightly more sculpted handle, which feels more comfortable for longer sessions. The NV352’s handle is straightforward and gets the job done, but after extended vacuuming the NV501 simply feels nicer in hand. Another small touch: the NV501’s tool storage design keeps accessories more securely in place, while the NV352 can sometimes feel like the tools rattle loosely. Again, the difference isn’t functional but contributes to a perception of refinement.
Long-term durability impressions
Having used both, the NV501 feels like it will shrug off years of use without as many cosmetic scuffs. The glossy finish resists scratches better, while the NV352’s lighter plastic tends to show wear earlier. That said, lighter vacuums often live longer simply because they are less fatiguing to use—you’re less likely to slam them into corners out of frustration. In practice, both are built to last if maintained, but the NV501 looks and feels more like a machine you’d be proud to leave in plain sight, whereas the NV352 feels more utilitarian.
Summing up design and build
The NV501 is clearly the more premium of the two in terms of design. It feels sturdier, has helpful headlights, carries itself with more stability, and gives the impression of being engineered with longevity in mind. The NV352, however, has its own strengths: it’s lighter, easier to carry, and has a slightly larger dust cup. Both share the same Lift-Away system and sealed HEPA design, but their personalities are different. The NV501 is the solid, refined worker that inspires confidence; the NV352 is the nimble, stripped-down partner that makes cleaning feel less like hauling a machine and more like wielding a tool.
Performance
Performance is ultimately where a vacuum earns or loses its reputation. No amount of sleek design or ergonomic comfort can make up for weak suction, poor brushroll action, or lackluster results on different flooring types. Both the Shark NV501 Rotator and the Shark NV352 Navigator are proven performers in everyday homes, but their differences become clearer once you run them across carpets, hardwood floors, and the many awkward corners of a house. Each machine has its strengths, and while they share the same motor class, the way that power is translated into cleaning makes them feel distinct.
Motor power and suction
Both vacuums are built around a 1200-watt, 10-amp motor, which puts them solidly in the mid-to-upper tier for corded uprights. This means they both deliver suction that feels strong and consistent, with enough airflow to pull embedded dirt from medium to high-pile carpets. Importantly, neither vacuum offers variable suction control—it’s a “full throttle all the time” approach. That can be a plus if you like simplicity, though it can occasionally feel like too much power when trying to clean lightweight rugs or curtains. For those situations, you can always vent a little suction through the hose or lift the head slightly to reduce the seal.
In practice, suction feels virtually identical between the NV501 and NV352. Both latch onto carpet fibers with authority, and both can sometimes feel like they’re self-propelling because of the vacuum seal. The difference is in how the machines manage that power: the NV501’s heavier weight keeps it firmly grounded, while the NV352’s lighter build means it occasionally clings too tightly to plush surfaces, requiring you to adjust your technique.
Carpet cleaning performance
On standard wall-to-wall carpet, both vacuums shine. Their brushrolls dig into fibers and lift debris effectively, pulling up sand, crumbs, and the fine dust that dulls carpet over time. The NV501, because of its extra three pounds of weight and slightly broader nozzle, tends to feel more “planted” as it glides over carpet. This can create cleaner lines in high-pile rugs and makes it easier to maintain consistent contact with the floor. The headlights also come into play here—being able to see tiny particles illuminated against the carpet fibers makes it easier to spot where you’ve already cleaned and where you’ve missed.
The NV352 performs nearly as well in actual dirt pickup but feels a little different. Its lighter body makes it easier to maneuver, which is useful for quick passes in a bedroom or living room. On very plush carpet, however, the NV352 can sometimes feel like it’s sticking to the floor more aggressively than the NV501, requiring you to pull it back with more effort. It’s not a deal-breaker, but it does highlight how weight can actually be an asset in some cleaning scenarios.
Hard floor performance
When it comes to hard floors, both vacuums offer the ability to switch off the brushroll. This is important for avoiding scratches on hardwood and for preventing the brush from scattering debris across smooth surfaces. With the brush off, suction alone does the heavy lifting. Both the NV501 and NV352 manage fine dust, grit, and everyday crumbs with ease, but technique matters. Because neither has a soft roller head like modern stick vacuums, you’ll get the best results by moving the vacuum in slow, overlapping passes rather than whipping it across the floor.
The NV352 feels slightly better suited for hard floors simply because it’s lighter. You can pivot and redirect it with less effort, which makes cleaning larger areas of wood or tile less fatiguing. The NV501 still performs strongly, but its extra weight makes it feel less nimble in wide open hard floor spaces. The headlights on the NV501 give it a small edge when cleaning in dim areas like under cabinets or along dark tile grout lines—you can see dust bunnies and crumbs more clearly.
Edge and corner cleaning
Edge cleaning is another area where subtle differences emerge. Both vacuums do a commendable job at pulling debris from along baseboards, thanks to their sealed suction paths and narrow nozzle edges. The NV501 has a slight advantage here, mainly because its headlights reveal the dust that tends to accumulate in corners and along walls. Being able to see the problem areas helps you adjust your passes and actually clean them fully. The NV352 still picks up debris well but leaves you relying more on guesswork and ambient light to ensure you haven’t missed anything.
Handling pet hair
Both vacuums are strong performers with pet hair, which is a make-or-break category for many households. Their brushrolls handle fur well, pulling it up from carpet without much issue. On hardwood, the strong suction prevents hair from blowing away or clumping in corners. The main distinction is in attachments: the NV501 frequently comes bundled with a motorized Pet Power Brush, while the NV352 more often ships with basic upholstery and crevice tools. That Pet Power Brush makes a huge difference when cleaning stairs, couches, cat trees, or car interiors. It’s not impossible to buy it separately for the NV352, but if you’re comparing out-of-the-box performance, the NV501 usually feels more pet-focused.
Stairs and upholstery
Performance on stairs and upholstery depends heavily on Lift-Away mode. Both vacuums allow you to detach the canister and carry it while using the hose tools, but neither supports powered Lift-Away—so the main floor nozzle’s brushroll won’t run in canister mode. That means stairs are best handled with smaller tools like the crevice nozzle or upholstery brush. The NV352 has a big advantage here due to weight: the lighter canister is easier to carry up and down steps. However, the NV501 claws back an advantage if you have the Pet Power Brush attachment, which makes quick work of fur and lint on fabric surfaces.
Above-floor cleaning
When using hose tools for shelves, blinds, or ceiling corners, both vacuums deliver ample suction. The NV501 is slightly more stable when you’re tugging on the hose without detaching the canister, thanks to its heavier base. The NV352, by contrast, can tip if you stretch too far without counterbalancing. Once you detach the pod, the NV352’s lighter weight makes it easier to carry one-handed while you use the hose with the other hand. Both pods are comfortable to use for about 10 to 15 minutes at a time before fatigue sets in.
Long cleaning sessions
Sustained cleaning performance also matters. Because both vacuums are bagless, suction can decline if the dust cup gets packed too full. The NV352’s slightly larger cup means you can clean longer without stopping to empty it. On the NV501, you’ll likely pause more often to dump debris. That said, both vacuums maintain strong suction until the fill line is reached, and emptying is quick thanks to bottom-release cups.
Performance on rugs and delicate flooring
Lightweight throw rugs are a test for any powerful upright. Both the NV501 and NV352 can lift or bunch small rugs if you’re not careful. The NV352, being lighter, is easier to control in these situations—tilt the head slightly and you can glide over a rug without it being sucked up. The NV501, while heavier, sometimes feels too aggressive on lightweight mats. For delicate flooring like antique wood, both vacuums handle it fine with the brushroll switched off. Their rubberized wheels protect surfaces, and their sealed suction pulls debris without scratching.
Everyday usability
In day-to-day use, performance is more than just raw suction. It’s about how consistently a vacuum delivers results with minimal frustration. The NV501’s headlights and stable stance make it easy to trust that you’re picking up everything, even in darker corners. The NV352’s light weight makes it more inviting for quick, frequent cleanups, which can lead to a cleaner home overall simply because you’ll reach for it more often. Both vacuums are strong performers, but they excel in slightly different rhythms: the NV501 for thorough weekly deep cleans, the NV352 for nimble daily upkeep.
Summing up performance
On carpet, both vacuums are excellent, with the NV501 feeling more grounded and consistent while the NV352 provides agility. On hard floors, both get the job done with brushrolls off, but the NV352’s lightness gives it a small advantage in handling. Edge cleaning and visibility tilt toward the NV501 thanks to its headlights. For pet owners, the NV501’s typical inclusion of a motorized pet tool makes it the stronger choice, though the NV352 can be just as capable with an upgraded toolkit. Stairs and upholstery are easier with the NV352 due to lighter weight, though again the NV501 wins if you value the pet brush.
Performance is less about which vacuum is objectively better and more about which one fits your cleaning style. If you want thorough, methodical cleaning with extras like headlights and a stable base, the NV501 shines. If you prefer a lightweight, grab-and-go workhorse that can still deep-clean carpets with authority, the NV352 feels like a better match.
Filtration & Allergen Control
For many households, suction power is only half the battle. The other half is what happens to all the dust, dander, and fine particles after they’re sucked into the vacuum. A machine that leaks dusty air back into the room can leave allergy sufferers sneezing even after the floors look spotless. This is where filtration and overall allergen control play a crucial role, and it’s an area where both the Shark NV501 and NV352 have a lot to offer. While they share the same general filtration philosophy, the way they present and implement these systems differs slightly.
Sealed system design
Both vacuums feature what Shark markets as a completely sealed system. This means that the air entering the vacuum is forced through a specific airflow path with minimal leakage, ensuring that dust and allergens do not escape through cracks, seams, or around the dust cup. In cheaper vacuums, even if there’s a HEPA filter, unsealed gaps in the body can let fine dust bypass the filter entirely and blow back into the room. By contrast, a sealed system ensures that all air is forced through the filtration components before exiting.
This design is particularly important for people with allergies or asthma. It reduces the presence of microscopic irritants in the air after cleaning, making the vacuum a tool not just for surface tidiness but for overall indoor air quality. Both the NV501 and NV352 perform well in this regard, though the NV501 highlights the “Anti-Allergen Complete Seal” branding more prominently, positioning itself as the more allergy-conscious model even though the NV352 uses the same core principle.
HEPA filtration
Both models include a HEPA filter, which is capable of trapping 99.97% of particles as small as 0.3 microns. In real-world terms, this means that pollen, dust mite waste, pet dander, and fine dust—the common culprits behind allergy symptoms—are captured and retained. HEPA filters are an industry benchmark for allergen control, and it’s reassuring to see them included in both vacuums.
The placement of the HEPA filter differs slightly in these designs, but functionally the outcome is the same. The filter sits in the exhaust air path, catching anything that escapes the primary foam and felt filters before the air is released back into the room. The result is cleaner air during and after vacuuming, which is especially noticeable if you have sensitivities or if your home is prone to dust accumulation.
Multi-stage filtration
Each vacuum relies on multiple stages of filtration, not just the HEPA component. First, larger debris is trapped in the dust cup through cyclonic action. This helps prevent larger particles from clogging the filters prematurely. Then, pre-motor foam and felt filters capture medium and fine particles before air reaches the motor. Finally, the HEPA filter traps the smallest particles before air exits the vacuum.
This layered approach is critical to both performance and filter longevity. Without the foam and felt filters, the HEPA filter would quickly become overloaded, reducing suction and requiring frequent replacement. With the multi-stage design, maintenance is simpler and performance stays consistent for longer stretches.
Maintenance for sustained allergen control
Good filtration isn’t just about design—it depends on proper upkeep. Both vacuums use washable filters, which keeps costs low but requires diligence. The foam and felt filters should be rinsed every few months, more frequently in homes with pets or heavy dust. They must dry completely before being reinstalled to prevent mold or odors. The HEPA filter, while washable, needs less frequent attention—usually once every couple of years, depending on usage.
If you neglect filter maintenance, both vacuums can lose suction and potentially leak dust. On the other hand, with regular care, these filters can last for years without needing replacements. For allergy-prone households, it’s worth keeping an extra set of filters on hand so you can swap them while one set dries.
Real-world impact
The difference between a sealed HEPA vacuum and a standard bagless upright without one is immediately noticeable in daily life. With the NV501 and NV352, you don’t get the faint dusty smell that sometimes lingers after vacuuming with lower-end machines. Instead, the air feels fresher, and allergy sufferers are less likely to experience flare-ups after cleaning.
The NV501’s slightly more premium build may help maintain seal integrity over time, as its thicker plastics and tighter latches can resist wear a little better. Still, the NV352’s system is highly effective in practice. The end result is that both vacuums allow you to not only remove visible dirt but also make your home environment feel tangibly cleaner.
Conclusion on filtration
Filtration and allergen control are standout strengths for both the NV501 and NV352. They share the same essentials: sealed systems, HEPA filters, and washable multi-stage filtration components. These features make them excellent choices for anyone concerned about allergies, asthma, or simply maintaining a healthier home environment. The NV501 places more emphasis on allergy branding and has a slightly more robust feel in terms of sealing, but the NV352 delivers virtually the same performance in practice. In this category, it’s less about one being better than the other and more about recognizing that both far surpass the filtration capabilities of many similarly priced uprights.
Maintenance & Cleaning
One of the biggest reasons many people either love or abandon a vacuum over time isn’t just suction power or maneuverability—it’s how much effort it takes to keep the machine in good working order. Maintenance isn’t glamorous, but it determines how long your vacuum lasts, how strong the suction stays, and whether the machine becomes a joy or a chore to use. Both the Shark NV501 Rotator and the Shark NV352 Navigator are designed to be user-friendly in this department, but there are clear differences in dust cup design, filter care, brushroll access, and overall long-term upkeep.
Dust cup size and emptying process
The NV501 comes with a dust cup capacity of about 1.3 quarts, while the NV352 offers slightly more at 1.4 quarts. On paper, this difference is negligible, but in real use the NV352’s cup can feel like it holds just enough extra debris to delay emptying. For homes with pets or a lot of tracked-in dirt, that small edge is noticeable.
Both vacuums use bottom-release dust cups, which means you simply hold the canister over a trash bin and press a button to release the trap door. This design minimizes the need to touch dirt directly, though fine dust often clings to the walls of the cup. The NV501 has a slight advantage here because its dust cup is a bit taller and narrower, which makes the debris funnel downward more cleanly. The NV352’s wider design sometimes requires a shake or two to dislodge clingy pet hair or static-charged lint.
Emptying frequency depends heavily on household conditions. A small apartment with minimal carpet might only require weekly emptying, while a large home with pets might demand multiple dumps per session. Regardless, both cups are transparent, so you can easily see when it’s time.
Cleaning the dust cup
Occasionally, both dust cups benefit from a deeper clean. Pet hair, dust, and fine powder can leave behind a film that affects odor or airflow. Both cups detach easily from the main body and can be rinsed with water, though they must be completely dry before reattaching. The NV501’s locking mechanism feels slightly sturdier, while the NV352 uses a simpler clip system that works but feels less premium. In practice, both are easy enough to manage, and the difference only shows up in how satisfying the build feels in hand.
Filter maintenance
Filter care is a shared responsibility across both vacuums. Each one uses foam and felt pre-motor filters along with a HEPA filter. The foam and felt filters should be washed under cold water about every two to three months for average households, more often if you’re dealing with pets or heavy dust. The HEPA filter needs attention less often—roughly once every two years.
The NV501 hides its filters behind a latch that feels solid and well-fitted, giving you confidence that the seal will hold strong after replacement. The NV352 uses a more basic access door that pops on and off. Both are easy to access without tools, which is a key advantage compared to some vacuums that require screwdrivers just to reach their filters.
Washing is simple: rinse under running water until clear, squeeze out excess, and let them air dry for at least 24 hours. Neither vacuum requires or recommends soap. The foam filter especially can trap odors, so washing regularly is not just about suction performance but also about keeping the machine smelling fresh.
Brushroll access and hair removal
Brushroll care is one area where many vacuums frustrate users, but both the NV501 and NV352 make it manageable. The brushrolls are removable for cleaning, which is crucial for homes with pets or long-haired occupants.
On the NV501, the brushroll cover pops off with a simple latch, revealing the roller for easy removal of tangled hair. The brushroll itself is fairly thick, which means long hair tends to wrap around it quickly. Fortunately, the design includes grooves along the roller where you can slide scissors to cut away the buildup.
The NV352 uses a slightly less refined system but still allows access to the brushroll. Its roller is narrower, which means hair and string tend to tangle more tightly. That can make cleaning take a little longer, but the end result is the same: with occasional attention, both machines stay clear and effective.
Neither vacuum uses a self-cleaning brushroll design found in some newer Shark models, so manual intervention is required. Depending on household conditions, you may find yourself cleaning the roller every few weeks. Pet owners, in particular, will want to stay on top of this chore.
Hose and wand cleaning
Over time, hoses can collect fine dust, pet hair, or even the occasional toy or sock. Both vacuums allow easy detachment of the hose for cleaning or checking clogs. The NV501 has a slightly sturdier-feeling hose connection, while the NV352’s is more lightweight. In both cases, you can run a long, flexible brush or even a dry cloth through the hose to clear debris.
The metal extension wand on both vacuums is durable and unlikely to clog, but occasional wiping helps maintain a clean surface. If suction ever feels reduced, checking the hose for obstructions is one of the first troubleshooting steps.
Belt and motor longevity
Both vacuums use belt-driven brushrolls. The belts are designed to last years under normal use, but they can wear down if the roller is constantly clogged or obstructed. Fortunately, replacements are inexpensive and relatively easy to install with a screwdriver. Keeping the brushroll clear and filters clean goes a long way in extending belt and motor life.
The motors themselves are reliable, provided airflow remains unobstructed. Regular filter maintenance is the single most important step in ensuring these vacuums run for years without overheating or losing power.
Odor management
Bagless vacuums can sometimes develop odors from accumulated pet hair or fine dust. Both the NV501 and NV352 benefit from occasional deep cleaning of the dust cup, hose, and filters to prevent smells. Using baking soda on carpets and vacuuming it up can also help deodorize the machine naturally. Because both vacuums have sealed systems, they’re less prone to pushing odors into the air during cleaning compared to unsealed models.
Long-term durability of parts
Plastic latches, dust cup hinges, and brushroll covers are the parts most prone to wear over time. The NV501 feels a little sturdier in these areas, with thicker plastics and more reassuring clicks when attaching or detaching components. The NV352, while reliable, uses slightly thinner plastics that may feel looser after years of use. However, Shark parts are widely available, so even if a latch or clip wears out, replacements are not difficult to obtain.
Day-to-day upkeep
In daily use, maintenance boils down to three main routines: emptying the dust cup before it gets too full, rinsing filters every few months, and cutting away hair from the brushroll when needed. Both vacuums make these tasks straightforward enough that they don’t become deal-breakers. Compared to bagged vacuums, you’ll save money on consumables, though you trade that for the occasional filter wash and dust cup rinse.
Overall ease of maintenance
Between the two, the NV501 edges out slightly in terms of build quality and ease of dust cup emptying, while the NV352 holds an advantage with a marginally larger cup and lighter parts that are easy to handle. In practical terms, maintenance requirements are nearly identical, and both are among the easier uprights to keep in good condition.
Final thoughts on maintenance
Maintenance and cleaning aren’t glamorous categories, but they determine whether your vacuum feels like a partner or a burden. Both the NV501 and NV352 score well here, with user-friendly dust cups, washable filters, accessible brushrolls, and straightforward designs. Neither will surprise you with hidden costs or convoluted upkeep. The NV501 feels slightly more premium in hand, while the NV352 wins on simplicity and slightly larger capacity. For long-term owners, both machines prove reliable with basic care, making them strong choices for anyone who wants a vacuum they can keep running smoothly for years.
Energy Efficiency & Noise Levels
Vacuum cleaners are often judged first by how well they clean, but energy use and noise output can make or break the experience of living with one over the long term. A machine that’s efficient saves you money and puts less strain on the environment, while a quieter vacuum means you can clean without feeling like you’re starting a construction project in your living room. Both the Shark NV501 Rotator and Shark NV352 Navigator are upright models with similar motors, yet they present subtle differences in efficiency, sound quality, and the way noise interacts with their design.
Power consumption and efficiency
Both vacuums operate at around 1200 watts, a fairly standard rating for upright vacuums. This places them squarely in the middle ground: powerful enough to generate strong suction but not so power-hungry that you feel it on your electricity bill. Neither vacuum has an “eco mode” or adjustable suction settings like some high-end models, but both balance performance with reasonable energy draw.
Over the course of a year, assuming weekly cleaning sessions in a medium-size household, the electricity cost difference between these models and more efficient alternatives is minimal—just a few dollars at most. In practical terms, their wattage is efficient enough for the average user while still delivering strong cleaning.
The NV352 has a slight edge in efficiency because of its lighter build. With less weight to drag across carpet and a simpler airflow design, it occasionally feels like it requires fewer passes to achieve the same results. The NV501, however, compensates with broader cleaning coverage thanks to its larger head, so the overall difference in time and power usage tends to balance out.
Motor performance and longevity
Energy efficiency also ties into how hard the motor has to work. Both machines use Shark’s cyclonic separation system to keep dirt from clogging filters too quickly. This ensures steady suction without overstraining the motor. With proper maintenance—keeping filters clean and the brushroll clear—neither model shows signs of motor strain even after years of regular use.
The NV501’s motor housing is slightly bulkier, which helps dissipate heat more effectively. This means the machine runs cooler during longer cleaning sessions. The NV352 gets warm more quickly, though not to concerning levels. Still, in homes where long cleaning sessions are the norm, the NV501 might feel a little more robust in terms of thermal efficiency.
Noise output: decibels and perception
Noise is a subjective factor. Both vacuums fall into the moderate range for upright machines, producing around 76–78 decibels during operation. This is comparable to a loud conversation or a running shower. Neither model is whisper-quiet, but neither is painfully loud.
Where they differ is in the quality of the noise. The NV501 produces a slightly lower-pitched hum that many users describe as less harsh on the ears. Its bulkier housing likely contributes to this, dampening some of the higher frequencies. The NV352, by contrast, has a sharper, higher-pitched tone. While not unbearable, it feels more noticeable, especially in smaller spaces where sound echoes.
If you vacuum at night, live in an apartment with thin walls, or have pets and children sensitive to noise, the NV501 may feel more comfortable to use. The NV352’s noise profile is fine for daytime cleaning but can feel intrusive in quiet households.
Noise in different cleaning modes
Both vacuums are slightly louder on carpet than on hard floors. The brushroll adds mechanical noise as it spins and agitates fibers. On bare floors with the brushroll turned off, both machines are a touch quieter. The NV501’s hum is smoother in these conditions, while the NV352 still retains that higher-pitched whine.
When using the lift-away mode for above-floor cleaning, noise perception shifts again. With the motor closer to you in handheld mode, both vacuums seem louder, though the actual decibel levels don’t change. This can be tiring if you’re doing long handheld sessions, but it’s a common trade-off for portable upright designs.
Vibration and handling
Noise isn’t just about sound—it’s also about vibration. The NV501 has better insulation around its motor, resulting in less vibration transmitted to the handle. The NV352, while still comfortable, has a more noticeable buzz in the grip when running. Over time, this can make the machine feel louder because your hands and arms are absorbing some of the vibration.
Household impact
Noise and efficiency affect how the vacuum fits into your daily life. With the NV501, you can clean while someone else watches TV in the next room without them needing to crank up the volume to maximum. With the NV352, you might get a few more complaints. For families with babies, pets that spook easily, or shared living situations, this difference could matter.
Energy-wise, both machines are reasonable. You won’t notice a spike in your power bill, and their wattage is efficient compared to older or bulkier uprights. They don’t carry energy certifications like some smaller appliances, but in real-world terms, they strike a good balance.
Long-term perspective
Over years of use, energy efficiency and noise management are about consistency. Both vacuums maintain their suction without requiring the motor to work harder, which helps avoid rising noise levels due to strain. Cheaper vacuums sometimes get louder as filters clog and motors struggle. The NV501 and NV352, with proper maintenance, hold steady in their sound output and power draw.
Final thoughts on efficiency and noise
Between the two, the NV501 feels like the more refined machine in terms of sound. Its lower hum, reduced vibration, and cooler motor operation give it a more premium feel during long sessions. The NV352, while perfectly functional, has a sharper tone that can grate after a while. In terms of energy, they’re essentially equals—efficient enough for everyday use without noticeable cost differences.
If quiet operation is a high priority, the NV501 earns the edge. If you’re more concerned with overall simplicity and can tolerate a slightly sharper noise profile, the NV352 holds its own. Either way, both models represent a good balance of performance, energy efficiency, and manageable sound levels, especially compared to louder, less efficient uprights in the same category.
Ergonomics & Usability
A vacuum cleaner can have all the suction power in the world, but if it’s awkward to maneuver, heavy to lift, or clumsy to use on stairs, it quickly becomes a frustration. Ergonomics and usability matter just as much as raw cleaning power, because they determine how often you’ll actually want to pull the machine out of the closet. Both the Shark NV501 Rotator and the Shark NV352 Navigator are upright vacuums with Shark’s familiar Lift-Away system, which gives them flexibility beyond standard uprights. Yet they differ in weight, handle design, maneuverability, and everyday convenience. Let’s break down how each performs when it comes to the user experience.
Weight and handling
The Shark NV501 weighs in at around 15.5 pounds, while the NV352 comes in a little lighter at about 12.5 pounds. On paper, that three-pound difference doesn’t sound dramatic, but in practice it’s noticeable, especially when moving the vacuum up and down stairs or lifting it into handheld mode. For smaller users or anyone with back or joint issues, the NV352 feels more manageable.
That said, the NV501 distributes its weight well, thanks to its slightly bulkier base and rotating steering system. When pushing it across carpets, it feels stable and controlled, almost gliding despite the extra heft. The NV352 is nimble and light, making it less tiring for long cleaning sessions, though it can feel less anchored on thicker carpets where the suction pulls strongly against the fibers.
Maneuverability
Both vacuums feature swivel steering, which makes navigating around furniture easier than with rigid upright designs. The NV501 shines here, with its advanced Rotator steering system. The pivoting head turns more smoothly and requires less wrist movement to guide around table legs, sofas, or bed frames. For users who vacuum in tight spaces or have lots of furniture, this fluid motion is a real plus.
The NV352 also swivels but with a more basic mechanism. It still allows turns without lifting the vacuum, but it feels a little stiffer and requires more effort to guide precisely. For open areas, this difference is negligible, but in crowded rooms, the NV501 gives you a more effortless experience.
Lift-Away function
One of Shark’s biggest innovations is the Lift-Away feature, where the canister detaches from the upright frame for portable cleaning. Both the NV501 and NV352 have this, and it’s a game-changer for stairs, upholstery, or tight spaces.
In Lift-Away mode, the NV352 feels noticeably easier to carry, thanks to its lighter body. Holding the canister in one hand while using the hose with the other is far more comfortable over long periods. The NV501, while perfectly functional in this mode, does weigh more, which can lead to arm fatigue during extended handheld use.
However, the NV501’s design feels more premium here, with smoother latches and a more solid click when detaching and reattaching the canister. The NV352’s mechanism is simpler but effective—it just doesn’t give the same polished impression.
Cord length and reach
Both vacuums come with a 25-foot power cord, which is adequate for small to medium homes but may require repositioning in larger spaces. Neither has a retractable cord, so you’ll need to wrap it manually around the hooks.
For above-floor reach, both models include a hose and wand system. The NV501 offers a bit more flexibility with slightly longer hose length and smoother wand extension. This makes it easier to clean ceiling corners or drapes without repositioning the vacuum base. The NV352 can reach high spots too, but its hose has more tension, so it tends to tug back if stretched too far.
Controls and adjustments
Usability also comes down to how easy the controls are to access. The NV501 places its main power button and brushroll switch conveniently on the handle, allowing quick changes while vacuuming. Switching from carpet to bare floor is seamless, and you don’t have to stop mid-cleaning.
The NV352 uses more basic controls located lower on the vacuum body. You can still adjust modes, but it requires a pause and a quick reach down. It’s not a dealbreaker, but the NV501 feels more refined and user-focused in this respect.
Attachments and accessory use
Both vacuums come with a standard set of tools—crevice tool, dusting brush, and upholstery nozzle. The NV501 typically includes an additional wide upholstery tool and sometimes a premium pet power brush, depending on the package.
Using attachments is straightforward with both, but the NV501 has slightly easier onboard storage. Its caddy keeps tools accessible without feeling cluttered. The NV352 also stores attachments onboard but with a simpler clip system that occasionally feels less secure. If you frequently switch between tools while cleaning, the NV501 makes this smoother.
Stairs and above-floor cleaning
Stair cleaning is a common challenge for uprights. With the Lift-Away feature, both models handle stairs much better than traditional vacuums. The NV352 is the clear winner here because its lighter weight makes carrying the canister far less of a burden. You can easily hold it in one hand while cleaning stairs with the other.
The NV501 works on stairs too, but holding the heavier canister for extended periods can get tiring. Its advantage is in stability: when left on a landing or flat step, it feels sturdier than the NV352, which can sometimes wobble.
User comfort and ergonomics
Handle comfort is another factor in usability. The NV501 features a well-padded handle with a slightly angled design that feels natural in hand. Long cleaning sessions put less strain on the wrist. The NV352 has a simpler, straight handle that works fine but doesn’t feel quite as ergonomic.
Weight distribution also affects how much pressure you feel when pushing and pulling. The NV501’s balanced design means less effort is needed to push across thick carpet, while the NV352’s lighter frame can feel like it drags more against resistance. On hard floors, however, the NV352 glides with ease, almost like pushing a lightweight stick vacuum.
Storage considerations
Both vacuums are relatively tall and take up a similar footprint in storage. The NV501, with its bulkier body and additional onboard tools, feels slightly more imposing in a closet. The NV352, being lighter and slimmer, tucks away more easily. Neither vacuum folds or compacts for storage, so users with very tight closet space may need to plan accordingly.
Learning curve and day-to-day convenience
Neither vacuum has a steep learning curve. Plug it in, switch modes, and go. The NV352 is arguably the more straightforward of the two, with fewer controls and a lighter feel. The NV501 requires slightly more familiarization due to its more advanced steering and handle controls, but once learned, it feels more intuitive and efficient.
For day-to-day convenience, both models deliver dependable usability, but the NV501’s smoother steering and more accessible controls give it a more polished experience. The NV352 wins when it comes to simplicity and lightweight handling, making it appealing to users who prioritize ease of carrying above all else.
Final thoughts on ergonomics and usability
When it comes to ergonomics and usability, the choice depends heavily on your household setup and physical preferences. The NV352 is lighter, easier to carry in Lift-Away mode, and more compact for storage. It suits smaller homes, users who struggle with heavier machines, and those who clean a lot of stairs.
The NV501, on the other hand, feels more refined in daily operation. Its steering is smoother, its handle is more comfortable, its controls are better placed, and its onboard storage is tidier. For larger homes with lots of furniture to navigate around, the NV501 makes vacuuming less of a workout.
Both vacuums are user-friendly, but they appeal to different types of users. If you value lightweight simplicity, the NV352 will win you over. If you want premium comfort and control, the NV501 feels like the smarter long-term investment.
Pet-Friendliness
For many households, pets are part of the family, which means their hair, dander, and occasional messes are also part of daily life. A vacuum’s ability to handle pet-related cleaning challenges is often the deciding factor when choosing between models. Upright vacuums in particular need to manage hair tangles, embedded fur in carpets, dander buildup, and even stray litter or food pellets that inevitably find their way onto floors. Both the Shark NV501 Rotator and the Shark NV352 Navigator are marketed as versatile machines, but their performance in a pet-heavy home environment reveals subtle strengths and weaknesses.
Hair pickup on carpets
One of the most demanding tasks for any vacuum is removing pet hair from carpet fibers. Dogs and cats shed differently, but in both cases the hair tends to weave into the pile, making it difficult to remove. The NV501 performs impressively here. Its brushroll, combined with strong suction, lifts hair effectively without requiring repeated passes. Even longer strands—common with breeds like golden retrievers or Persians—are pulled into the bin rather than left clinging stubbornly to the fibers.
The NV352 also does well, though its slightly lighter suction and narrower cleaning path mean you sometimes need an extra pass or two for thick carpets covered in fur. Still, it clears hair efficiently enough to make a noticeable difference after just one session. For pet owners with primarily low- to medium-pile carpets, the NV352 holds its own, but the NV501 feels more aggressive and efficient on high-pile rugs and plush surfaces.
Hair pickup on hard floors
On hard floors, the NV352’s lighter build gives it an advantage. It glides more easily and doesn’t scatter hair as much. The NV501 still performs admirably, but the more powerful brushroll can occasionally flick lighter clumps of fur around before suction pulls them in. This isn’t a dealbreaker, but it can add to the number of passes required in certain spots.
Both vacuums have brushroll shut-off options, which is particularly useful for hard floors. Turning off the brushroll reduces scattering and helps both machines pick up hair and dander more cleanly. The NV352 benefits more from this because of its simpler airflow, which feels optimized for smooth surfaces.
Upholstery and furniture cleaning
Pets love to lounge on couches, chairs, and beds, so a vacuum’s above-floor performance is critical. The NV501 excels with its accessory lineup, particularly when paired with its wider upholstery tool and optional pet power brush. These attachments dig fur out of fabric crevices effectively, making furniture look fresh again. The lift-away function makes it easy to tackle these areas without struggling to maneuver the entire vacuum body.
The NV352 also handles upholstery cleaning, though its included attachments are more basic. Its smaller upholstery tool works fine on cushions but requires more time to cover larger pieces of furniture. When paired with the crevice tool, it does a decent job in corners and seams, but it lacks the dedicated pet tool advantage that often comes bundled with the NV501.
Stairs and portable pet cleanup
For households with pets that shed on staircases, the lift-away feature is a lifesaver. The NV352 shines here due to its lighter canister. Carrying it in one hand while cleaning stairs with the hose feels natural and less taxing. The NV501 works well too, but the heavier canister can cause fatigue during extended stair-cleaning sessions, especially if you have a multi-level home.
Both vacuums allow you to use attachments in this mode, which is perfect for stair treads that collect fur. The NV501’s wider selection of tools gives it an edge for more thorough cleanup, but the NV352’s lighter weight makes it easier for quick touch-ups.
Brushroll and hair tangling
One of the biggest frustrations for pet owners is dealing with hair tangling around the brushroll. Both the NV501 and NV352 use traditional bristle brushrolls rather than the newer self-cleaning models found in later Shark vacuums. As a result, long pet hair does wrap around the roller over time.
In real-world use, the NV501 is slightly better at resisting tangles due to its stronger suction pulling more hair directly into the airflow before it wraps. However, neither machine completely avoids buildup. Fortunately, both vacuums make it relatively easy to access the brushroll for cleaning. The NV501’s larger frame gives you more room to work when cutting out hair, while the NV352’s narrower design makes the job a bit fiddlier.
For households with multiple long-haired pets, this maintenance step will become routine. It doesn’t take long, but it’s worth noting that neither model eliminates the need for brushroll cleaning.
Filtration and dander control
Pet-friendliness isn’t just about visible fur—it’s also about invisible allergens like dander. Both vacuums are equipped with sealed HEPA filtration systems, which capture fine particles and keep them from being released back into the air. This is a significant advantage for households where allergy management is a concern.
The NV501’s slightly larger filter system and sealed design feel a little more robust, offering peace of mind for those especially sensitive to allergens. It also features more accessible filter placement, making it easier to maintain clean filtration on a regular basis. The NV352 still performs very well, but its smaller frame requires more frequent filter cleaning to maintain maximum efficiency.
Handling pet messes beyond fur
Pets bring more than just hair into the home. Kitty litter, kibble crumbs, and tracked-in dirt all need attention. Both vacuums manage these small debris types effectively. The NV352, being lighter and nimbler, feels better for quick cleanups on hard surfaces like near food bowls or litter boxes. The NV501, with its stronger suction, clears larger debris with fewer passes and is better suited for cleaning heavily soiled rugs near entryways.
Neither vacuum is designed to handle wet messes, so accidents like spills or pet vomit need to be dealt with before vacuuming. However, both machines excel at cleaning the dried aftermath once initial cleanup is complete.
Noise and pet comfort
Noise levels matter when cleaning around pets. The NV501’s lower-pitched hum tends to be less startling for animals, while the NV352’s higher-pitched tone can cause some pets to bolt at the sound. If you have skittish cats or nervous dogs, the NV501 may be the friendlier option. For pets accustomed to household noises, both vacuums are tolerable, but neither could be called whisper-quiet.
Durability in pet households
Owning pets often means vacuuming more frequently, which puts added strain on any machine. Both the NV501 and NV352 hold up well under heavy, pet-focused use. Their dustbins are sturdy, their seals hold firm, and their hoses resist clogging. Over time, the NV501’s slightly larger dustbin reduces the number of emptying trips during fur-heavy seasons, which is a small but appreciated convenience.
Final thoughts on pet-friendliness
When judged through the lens of a pet owner, both the Shark NV501 and NV352 deliver strong, reliable performance. The NV352 is lighter, easier to maneuver in quick sessions, and particularly good for hard floors and stairs. It’s a solid choice for smaller households with pets that shed moderately.
The NV501, by contrast, feels like the more complete solution for homes with heavy shedders, multiple pets, or allergy concerns. Its stronger suction, broader toolset, and slightly more refined filtration make it more capable of handling thick carpets, upholstery, and persistent dander. Its lower-pitched noise also makes it a bit friendlier to sensitive animals.
Neither vacuum is flawless—they both require regular brushroll cleaning and aren’t designed for wet messes—but both rise above many competitors in managing the realities of living with pets. Ultimately, your decision may come down to whether you prioritize lightweight convenience (NV352) or a more powerful, versatile system (NV501).
Conclusion
After putting the Shark NV501 Rotator and the Shark NV352 Navigator through their paces, it’s clear that both are strong contenders in the upright vacuum category, each appealing to slightly different users. The NV352 wins with its lighter weight, simpler design, and easier portability. It’s the kind of vacuum you can quickly grab for everyday messes without feeling like you’re hauling around heavy equipment. For apartments, smaller homes, or households where stairs are a constant cleaning challenge, its compactness is a real advantage.
The NV501, on the other hand, makes its case with refinement and capability. Its steering feels smoother, its handle more ergonomic, and its suction slightly stronger. It comes with more tools, offers better upholstery coverage, and feels built to handle larger, busier households—especially ones with pets or allergy concerns. While it’s heavier and takes up more room, it compensates with convenience features that make daily vacuuming less of a chore.
Both vacuums share Shark’s hallmark features—Lift-Away portability, HEPA filtration, and reliable suction—but they diverge in personality. The NV352 is the lightweight workhorse; the NV501 is the more premium all-rounder. Your decision comes down to lifestyle. If you want something easy to carry and simple to store, the NV352 is likely enough. If you want extra polish, more comfort in use, and stronger long-term versatility, the NV501 feels like the smarter buy.
Either way, both models prove why Shark has remained a go-to brand for upright vacuums. They’re durable, effective, and practical—machines designed to handle real-life cleaning rather than showroom demos. Choosing between them isn’t about finding the “better” vacuum but about picking the one that better fits your home, your pets, and your cleaning habits.
