Shark NV151 Navigator Swivel Pro Complete Upright Vacuum

3.9

(4)

Bottom Line

Choose the Shark NV151 for powerful pickup in a lightweight, swiveling upright; Skip it if you need Lift-Away portability or a tangle-resistant brush roll.

Best for

Budget-focused homes with mixed hard floors and low-to-medium pile carpet that want strong cleaning power, easy swivel steering, and simple above-floor tools for furniture and stairs.

Not for

Homes with lots of long hair or heavy shedding that want a self-cleaning roller, or shoppers who require Lift-Away portability, a headlight, or consistently smooth handling on every area rug.

Verdict

The NV151 Navigator Swivel Pro is a solid corded upright for shoppers who want a lighter machine that still pulls embedded dust and pet debris from mixed flooring. Reviews repeatedly praise the cleaning power, HEPA/sealed dust containment, and quick, tool-free setup, and many find the swivel head easy to guide around furniture. Tradeoff: it skips convenience touches common on pricier Sharks, especially a headlight and a self-cleaning brush roll, so long hair and heavy shedding can mean frequent roller cutting and cleanup. A smaller set of reviewers report short reach in practice, tipping when stretching the hose, or finicky behavior on some area rugs.

Pros

Assembly and Setup 4.8 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.8

Price & Value 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.4

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.
Emptying & Mess Control 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.4

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.
Onboard tool storage 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.4

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.
Airflow blowback 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.4

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.
Filtration / Dust Containment 4.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.4

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.
Overall opinion 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.3

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.
Pet-Ready Features 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.3

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.
Hard Floor — Fine Dust Pickup 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.3

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.
Weight 4.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.3

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.
Accessories & Tools 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.2

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.
Ease of use 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.2

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.
Suction & Airflow 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.2

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.
Upholstery / Above-Floor Pickup 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.2

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.
Hard Floor — Large Debris Intake 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.2

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.
Ongoing ownership costs (bags, filters, batteries) 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.2

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.
Dried-On Stain Removal 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.2

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.
Stair Cleaning 4.2 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.2

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.
Hair Pickup — Hard Floors 4.1 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.1

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.
Suitability for small spaces 4.1 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.1

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.
Hose length 4.1 ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.1

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.
Versatility 4.1 ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.1

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.
Build quality & durability 4.1 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.1

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.
Controls & UI 4.0 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.0

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.
Cord length 4.0 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 4.0

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.
Bin & Bag 4.0 ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.0

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.
Carpet — Low-Pile Pickup 3.9 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 3.9

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.
Hair Pickup — Carpets 3.9 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.9

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.
Suitability for heavy-duty use 3.9 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.9

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.
Cord management 3.9 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 3.9

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.
Carpet — High-Pile Pickup 3.8 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.8

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.
Comparative performance 3.8 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 3.8

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.
Overall durability/longevity 3.7 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.7

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.
Noise level 3.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 3.6

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.
Aesthetic design & finish 3.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.6

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.
Edge & Baseboard Cleaning (Hard Floors) 3.6 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.6

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.

Cons

Floorhead design 3.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 3.4

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.
Odor control 3.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.4

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.
Support & Reliability 3.4 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.4

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.
Maintenance requirements 3.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.3

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.
Storage footprint & upright-stand stability 3.3 ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.3

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.
Clogging & debris prevention 3.2 ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.2

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.
Scratch resistance 3.2 ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.2

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.
Under-Furniture Pickup 3.1 ★ ★ ★ ★ ★ ★ ★ ★ 2 reviews 3.1

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.
Area Rug Handling 3.0 ★ ★ ★ ★ ★ ★ ★ ★ 1 review 3.0

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.
Hair‑Wrap / Tangle Resistance 2.6 ★ ★ ★ ★ ★ ★ ★ ★ 1 review 2.6

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.
Headlight & LED lights 1.0 ★ ★ ★ ★ ★ ★ 1 review 1.0

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.

FAQ

Does the NV151 have Lift-Away (a removable canister)?

No. Reviews describe it as a standard upright, but it includes a hose and wand for above-floor cleaning like stairs, furniture, and blinds.

Is it good for pet hair?

Most reviewers say it picks up pet fur very well on carpets and upholstery and like the included pet tool. Several also note hair can wrap around the brush roll, so heavy-shedding homes may want a self-cleaning-roller model.

Does it have a headlight on the floorhead?

No. The missing headlight is one of the most common complaints, especially for spotting dust on hard floors or vacuuming in low light.

How well does it contain dust for allergies?

Many users highlight the HEPA filter and sealed system for keeping dust and allergens in the vacuum and reducing blowback. Keeping filters clean matters, as a few long-term owners mention odors if maintenance is neglected.

Is the cord and hose reach long enough for above-floor tasks?

Opinions vary. Many like the reach for ceilings and high dusting, while others wish the cord were longer or say the base can tip when the hose is pulled to its limit.

Will it work on area rugs and plush carpet?

Many users report strong carpet pickup, including on plush carpeting, but some say it can feel grabby or even stall on certain area rugs or shag. Adjusting suction helps for some, but rug-heavy homes may want to verify compatibility.
