Compare Shark NV151 Navigator Swivel Pro Complete Upright Vacuum vs Bissell ProHeat 2X Revolution Upright Carpet Cleaner

The included crevice, upholstery, and pet tools are frequently praised for couch, crevice, and above-floor cleaning. Some Amazon reviewers complain specific accessories they expected (such as a wide upholstery tool or round brush) were missing or hard to find.

Most reviewers like the included tool set—commonly highlighting the 2‑in‑1 pet upholstery tool (wet/dry) plus stair/tough-stain tools and a storage bag—though one comparison review notes certain configurations ship with few or no accessories and tool usefulness varies by model.

Design is often described as simple and minimalist. A few owners mention a more plastic feel than older versions and occasional cosmetic marks or wear.

Several users contrast it with older vacuums that blew dust back into the room, saying this model has minimal blowback and no spit-back on hard floors. This is closely tied to sealed filtration and strong suction.

One test-focused review notes moderate exhaust airflow and a rear exhaust design; drying performance relies more on passes and the chosen mode than on a powerful air blast.

Area rug handling is inconsistent: some users vacuum rugs successfully after adjusting suction, while others say the head sits too low, stalls, or stops on certain rugs. Shag-style rugs are specifically called out as a poor match by some owners.

Area rug results are generally good, but at least one review warns the brush action can snag or pull fibers from delicate/looped rugs—suggesting spot-testing and gentler settings when needed.

Assembly is consistently described as fast and tool-free, with components clicking into place in minutes. This is one of the most universally positive aspects across reviews.

Assembly is usually quick (around 10–20 minutes) but commonly requires a screwdriver for the handle. A couple reviewers say the manual/instructions could be clearer, though setup steps are straightforward.

Bagless dust cup emptying is usually described as easy, but capacity impressions vary widely. Some call the bin large, while others find it small or note a low fill line that forces frequent emptying in hair-heavy homes.

Build quality feedback ranges from sturdy, well-snapping parts to concerns about cheaper plastic materials and belt smells. It generally feels solid for the price, but not everyone expects premium longevity.

Build is often described as sturdy and well-made, with tanks and housings that feel robust. Minor durability-related complaints show up around dripping/leaking or fiddly tank openings rather than structural failures.

Performance on plush or thicker carpet is often positive, with reports of smooth gliding and strong extraction. Still, some say it can feel too grabby or struggle unless suction is reduced, and a few recommend avoiding very thick shag.

On low-pile and standard carpet, many users see strong pickup and noticeably fuller bins after one or two passes. Some still report needing extra passes or seeing a trace of dust left near the sides of the head.

Some users report the wand/tube can clog with hair and debris and mention a clog indicator/red light behavior; others say it stays clear when filters and brush roll are maintained. Clog complaints tend to come from hair-heavy households or heavy use.

Comparisons are often favorable versus cheaper brands and even some premium vacuums for day-to-day pickup, especially on mixed flooring. Dissenting voices prefer higher-end Sharks or other brands for tangle resistance, rug performance, or long-term durability.

In comparisons, it often lands as a top value pick and a strong performer in its price tier, but not always the outright best. Some reviews prefer HydroSteam/Big Green for toughest stains, while one test-heavy review recommends competing machines for better overall performance per dollar.

Controls are simple, with hard-floor vs carpet modes and an adjustable suction slider that users like for switching surfaces. Some wish the power switch were positioned higher on the handle for convenience.

Controls are generally simple and clearly labeled (mode selection plus trigger spray). The CleanShot foot button/spray is polarizing: some find it handy, others say it’s awkward to aim, messy, or not much better than extra passes.

Cord length sentiment skews mixed-to-negative: some reviewers like the reach, but many wish it were longer than older models or competitors and note there is no automatic rewind. Cord length matters more in larger rooms and multi-room runs.

Cord length is usually described as long enough for room-sized jobs (often cited around 22–25 ft), but at least one review complains the real length is shorter than advertised, and cord reach is still a limitation on larger areas.

Cord management is often cited as a pain point because it must be wrapped manually and can drag or tangle while vacuuming. Positives include cord clips/hooks that help keep it out of the way once you get used to routing it.

Cord wrap/hooks or ties are mentioned as convenient for tidy storage, though they don’t solve the overall bulk of storing a full-size carpet cleaner.

Swivel steering is widely praised for easy turns and navigating around furniture. However, a noticeable subset says it over-swivels or feels sloppy, and handling can feel less controlled on some carpets.

Most reviews report excellent stain-lifting on typical set-in messes (mud, wine, coffee, pet accidents) with a few passes and pre‑treating. Very old or deeply embedded stains can remain, and premium models like HydroSteam/Big Green tend to do better on the toughest jobs.

Ease of use is widely praised: quick setup, straightforward controls, and a lighter feel than many uprights. Common negatives are cord handling, occasional over-swivel behavior, and fatigue during long whole-home sessions.

Day-to-day use is often described as intuitive—‘like pushing a vacuum’—with simple fill/clean/empty steps. The main friction points are heft when full and occasional learning curve around solutions or CleanShot use.

Edge results are mixed: some users report good cleaning along walls and baseboards, while others note a small gap near edges that requires switching to the hose/crevice tool for a complete pass.

Emptying is typically simple with an easy-release, bottom-dump style, and many describe it as low-mess. The main downside is that frequent emptying can be necessary depending on bin size and how much hair/dust you collect.

Emptying is typically quick and straightforward, yet a few reviewers report messy moments—drips after finishing, puddling if the unit is stopped on carpet, or occasional leaks/spills depending on handling.

Reviews frequently highlight the HEPA filter and sealed dust containment for trapping allergens and reducing dust blowback, including positive mentions from allergy/asthma users. Long-term odor complaints show up occasionally when filters or odor components aren’t kept fresh.

Express mode is widely credited for quicker dry times, while Deep/Max modes can leave carpets damp for hours or even overnight. Reviewers often recommend extra ‘dry’ passes to speed up drying and reduce wet spots.

The floorhead earns praise for swivel maneuvering and general pickup, but complaints include limited under-furniture clearance, a narrower head that takes longer to cover rooms, and a brush/roller design that can trap hair or stall on some rugs.

Many owners say it removes pet hair from carpets effectively and reveals debris their old vacuums missed. Counterpoints include reports of needing multiple passes or preferring models with a self-cleaning roller for heavy shedding.

Hair pickup on hard floors is generally rated highly, especially for pet fur, with many owners impressed by what it collects after prior vacuuming. Results depend more on suction and technique than on tangle resistance.

Hair wrap is one of the biggest recurring complaints: long hair and pet fur often wrap the brush roll and require manual cutting or regular cleanouts. Several reviewers recommend stepping up to a Shark with a self-cleaning roller if hair is a daily issue.

Hard-floor fine dust pickup is frequently praised, including reports of less dust being kicked back into the air than with older vacuums. This aligns with strong suction and sealed filtration comments.

Most users report it handles larger debris well on hard floors, including pet mess and gritty dirt. A few note the head can grab certain rugs or feel less smooth when transitioning over thicker surfaces.

A frequent complaint is the lack of a headlight or LEDs on the floorhead. Many reviewers miss this feature for seeing dust on hard floors or vacuuming in low-light areas.

Multiple reviews clarify that ‘ProHeat/HeatWave’ helps maintain warm water temperature rather than actively heating cold water; users typically add hot tap water. Some describe warm airflow, but it’s not a true steam or boiler-style heater.

The extendable hose and wand are valued for reaching ceilings, blinds, and above-floor areas. Some users dispute the advertised reach, say the wand feels too long, or note the base can tip when the hose is pulled taut.

Hose length is typically reported as adequate for stairs and spot work (often around 8 ft, with some models closer to 10 ft). For larger staircases, users may still need to reposition or carry the machine.

Ongoing maintenance is expected: rinsing filters, clearing clogs, and cutting hair off the brush roll. Reviewers who keep up with these routines report better performance and fewer issues.

Maintenance is a strong point for many: removable nozzles/covers, accessible brush rolls, and easy tank rinse-outs. A minority note annoyances like hard-to-reach tank openings or needing extra cleanup during/after use, and newer ‘turbo’ style designs improve brush access.

Despite its weight, most reviewers say it’s easy to push and steer on carpet, with good reach using the hose. Handling drawbacks show up when lifting/carrying (front-heavy feel, stairs).

Noise feedback is mixed: several users call it relatively quiet or quieter than older Sharks, while others describe it as very noisy. Overall it trends tolerable but not silent.

Noise is a recurring complaint: multiple reviewers call it loud (some measured around the low‑80 dB range). ‘Turbo’ updates are described as only modestly quieter in real-world use.

A few reviewers say it leaves the air feeling fresher at first, but long-term owners sometimes report musty odors if filters aren’t cleaned or replaced on schedule. One reviewer also expressed caution about the odor-neutralizing component around kids/pets.

Many report carpets smell fresher after cleaning and solutions leave a pleasant scent, but strong pet odors may not disappear completely in one pass and can linger faintly.

Onboard storage for the main attachments is a convenience highlight, reducing the chance of losing tools. A few reviewers still want more dedicated storage space, such as a spot for spare filters.

Tool storage is mixed: several reviews mention a separate bag and limited onboard storage, which is fine for closets but less convenient if you want everything attached to the unit.

Washable filters are repeatedly called out as a cost saver because they can be rinsed instead of replaced frequently. Some users still buy extra filter sets so one can dry while the other is in use.

Longevity sentiment is split: many long-time Shark owners report years of service from older Navigators and expect similar life, while some users report early failures or worry about lighter, more plastic construction.

Overall sentiment is mostly positive, driven by suction, maneuverability, and value, with many repeat Shark buyers recommending it. Negative reviews focus on missing premium features (like a headlight), hair wrap maintenance, occasional rug handling issues, and sporadic reliability complaints.

Across reviewers, sentiment is mostly positive: many call it a strong, practical deep-cleaner that refreshes carpets and furniture, while a few lab-style tests rate it only mid-pack and question whether it’s the best buy versus cheaper rivals.

Unboxing feedback is generally positive: reviewers mention compact packaging and neatly organized accessories, making setup feel straightforward.

Many reviews position it as a pet-friendly upright thanks to strong suction and included pet tools, with multiple owners impressed by fur pickup on carpets and furniture. The main pet-related downside is brush-roll hair wrap, which can require frequent cleanouts in heavy-shedding homes.

Pet-focused features (pet tools, targeted solutions, odor/stain focus) are a major selling point. Most say it handles accidents and pet messes well; a few note the hair-trap/tool design isn’t perfect and some hair can still end up in the hose.

Value is a consistent theme: many see it as a budget-friendly upright that competes well with more expensive vacuums. A minority feel it’s overpriced if you need more features, better rug handling, or longer-lasting build.

Value is frequently praised—especially when discounted—because cleaning results approach pricier machines. A few reviewers still find it expensive for a corded, bulky cleaner or recommend cheaper alternatives with similar results.

Cosmetic durability is a minor but present theme, with mentions of scratches and some tools leaving marks on surfaces. These reports are not universal but suggest care is needed around delicate finishes.

A self-rinse/self-clean style tray/base is mentioned as helpful for flushing the system after a job, reducing post-cleaning hassle and helping avoid funky residue in the machine.

Mode settings (Max/Deep/Express) and solution delivery get good marks for flexibility, but some reviewers say Max uses a lot of water/solution and the CleanShot pre-treat can feel wasteful or ineffective compared with extra passes.

Stairs are generally manageable thanks to the hose/wand and lighter feel compared with heavier uprights. The main drawback is stability, as some users say the base can tip when pulling the hose during stair work.

Stair cleaning is frequently called out as a strength when using the hose and stair tool; results are good, but the unit’s weight can make carrying it between flights less convenient.

Several comparisons emphasize this is not a steam cleaner; Bissell’s HydroSteam models add steam for tougher, older stains, but the ProHeat 2X Revolution relies on hot-water extraction instead.

Several reviewers like that it stores in a closet or corner, but stability can be an issue. Multiple comments mention the vacuum can feel tipsy or tip over when using the hose/wand, requiring a hand to steady it.

Storage is a common drawback: reviewers describe it as bulky and needing a dedicated closet/corner, even though it stands upright. The cord can wrap neatly, but overall footprint is still sizable.

Most reviews describe very strong suction that pulls up noticeably more dirt, dust, and hair than prior vacuums. A smaller set of owners say power feels similar to other Sharks or takes multiple passes on rugs, especially compared with higher-end models.

Extraction/suction feels strong to many users during cleaning, but measured tests in a couple reviews put nozzle and hose suction below average. Net takeaway: adequate for pulling dirty water out, but not class‑leading.

Some professional or frequent cleaners report it holds up well with routine upkeep, suggesting it can handle heavier use. Others frame it as a good home vacuum that may wear faster or be harder to repair under commercial-style abuse.

Several reviewers highlight that it fits well in apartments, condos, and small storage spaces while still offering strong suction. People in larger homes sometimes want a longer cord or bigger bin to reduce interruptions.

Reliability experiences vary from trouble-free use (including frequent cleaning) to complaints about clogs, vibration, and occasional unit failure. Some also note repair/parts availability can be limited, reinforcing a replace-rather-than-repair perception.

Several reviews call out strong warranty coverage (commonly 5–6 years) and accessible support options, which helps offset concerns about owning a heavier, more complex cleaner.

Attachments are generally described as easy to swap, with parts that click into place and detach quickly. A few users still wish certain tools were included, but the change process itself is straightforward.

Attaching the hose and swapping tools is generally easy and quick, with click-in fittings that make spot and upholstery work straightforward.

Getting under low furniture is a common limitation for a standard upright design. Some users can reach under tables and chairs, but others say the head and body are too bulky for couches and low-clearance spaces.

At least one review notes a relatively low profile that helps it reach under furniture better than bulkier carpet cleaners, though clearance is still limited versus a normal vacuum.

Above-floor cleaning is a strength for many owners, especially using the pet tool on couches and the wand for curtains, vents, and ceiling fans. Reach is generally good, but pulling hard on the hose can make the base tip for some users.

Upholstery/spot tools get strong feedback for refreshing sofas, chairs, car mats, and pet beds. Some stains may take repeat passes, and one test review rates handheld extraction as average rather than exceptional.

The hose, wand, and tools make it useful for floors, furniture, and high dusting, adding versatility for a standard upright. It does not offer a Lift-Away detachable canister, which limits portability compared with other Shark lines.

Reviewers highlight versatility across wall-to-wall carpet, area rugs, stairs, and upholstery thanks to multiple modes and tools. It’s repeatedly noted as not intended for hard floors, so it’s best as a dedicated carpet/upholstery cleaner.

Tanks are easy to remove and refill/empty, and capacity is often seen as decent, but several reviews mention frequent dump/refill cycles on big cleanups. Design quirks show up: tall fill shape, small openings that are hard to scrub, and some models’ dirty-tank ‘full’ line limiting usable capacity.

Many users describe it as lightweight and easy to carry, including older owners who appreciate reduced strain. Others still find it heavy to lift or feel wrist/hand fatigue during long sessions, especially when using the hose.

Weight is commonly described as manageable while pushing but noticeable when carrying—especially once tanks are full. Several reviewers call it heavy/bulky for stairs, even if it maneuvers well on the floor.
