Compare Shark NV151 Navigator Swivel Pro Complete Upright Vacuum vs Simplicity Vacuums Allergy Upright Vacuum, S20EZM

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.

Included tools are usually described as basic but useful (commonly crevice and a combo dusting/upholstery tool). Several reviewers want a wider or softer dusting tool, and some add aftermarket pet or specialty attachments.

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.

A few comments call the vacuum simple, clean, or stylish, while others dislike cosmetic choices or mention broken trim/cover parts that are mostly aesthetic.

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.

Airflow blowback or scatter is specifically mentioned on hard floors by some users, including reports of particles being thrown back toward feet during use.

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 handling depends heavily on height setting and rug type. Some owners say it works well when adjusted up; others say it can grab edges, chew bindings, or feel too aggressive on certain rugs.

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 repeatedly described as simple and quick, typically sliding in the handle and attaching the hose, with minimal screws.

The bag-full indicator is viewed as helpful when present, but at least one owner reports it failing to reset after changing bags.

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.

The bagged system is a major selling point: owners like cleaner disposal, consistent suction, and less dust exposure than bagless designs. Bag capacity is often praised, but replacement cost and bag consumption (especially with heavy shedding or wool rugs) are frequent notes.

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 quality feedback is polarized: some praise sturdy materials (metal brush roll, aluminum wand, rubber bumpers), while others report cheap-feeling plastics, wobble, broken handles/covers, or hose issues over time.

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.

High-pile carpet performance is generally strong due to agitation and height settings, but some users find it hard to push or overly aggressive if set too low.

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.

Low-pile carpet results are typically positive, especially for everyday pickup and pet hair, though pushing effort can increase if suction is high and height is set low.

Medium-pile carpet cleaning is consistently praised, with multiple reports of lifting matted carpet and pulling embedded dirt and pet hair that previous vacuums missed.

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.

Some owners mention clogs or brush/belt issues that require disassembly, while others highlight visible clog indicators and easy access to the roller area for checks.

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.

Comparisons are common: many say it out-cleans certain Sharks/Dysons on carpet and pet hair, while at least one comparison favors a premium canister for ease and deep extraction despite higher upkeep.

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 usually described as straightforward, with height adjustment settings that are easy to use. The foot pedal placement is occasionally criticized for accidental shutoffs when bumping furniture.

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 perception varies: several reviewers call it long enough (often cited as 30 ft), while others say it is shorter than expected and requires frequent outlet changes in larger spaces.

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 is often praised as neat and practical, but multiple users wish for a retractable cord for convenience and to reduce cord management hassles.

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.

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 simple and satisfying on carpet, but usability drops for some due to weight when carrying, strong pull on thick carpet, short hose frustrations, or brush roll behavior during hose 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.

Edge and baseboard cleaning is highlighted positively by some owners, while others still avoid edges on delicate rugs due to brush aggression.

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.

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.

Filtration is a standout: multiple reviews highlight HEPA-style bags and filters, strong dust containment, and noticeable allergy relief versus bagless vacuums.

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.

The floorhead/brush system is powerful but divisive. Many emphasize strong agitation and carpet grooming; many also complain the brush roll runs continuously and can be too aggressive on hard floors and 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.

Hard-floor fine dust pickup is inconsistent: some users report very clean results, while others say the brush roll and airflow can scatter particles or require switching to other vacuums for hard floors.

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.

Large debris intake on hard floors gets mixed feedback, including complaints about litter or particles being thrown back during use in some homes.

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.

The headlight is frequently mentioned as useful for spotting debris, though at least one owner questions bulb longevity and whether the lights are true LEDs.

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.

Reach is a frequent theme: some are happy with the wand/hose extension for corners and drapes, while others say the permanently attached hose feels too short and can tug the vacuum toward them.

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 expectations are higher than some modern uprights: multiple owners mention periodic belt changes and watching filters/bags, and a few report recurring belt or brush issues.

Handling is mixed: some call it easy to maneuver with good wheel roll and a small footprint, while others find it awkward to lift onto steps, hard to push on thick carpet, or unstable/wobbly when parked.

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 common downside. Many describe it as loud, though a few say the tone is acceptable or less irritating than other vacuums.

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.

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.

Onboard tool storage is commonly praised as convenient and secure, helping reduce lost tools and making quick transitions easier.

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.

Ongoing costs are mostly about bags and periodic belts/filters. Many accept the trade for cleaner disposal and better dust control, but some find OEM bags or add-on tools expensive.

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.

Longevity reports are split: some claim many years across prior Simplicity units and expect long service due to replaceable parts, while others report failures around 1 to 2 years, frequent belt breaks, or brush/motor issues.

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.

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 owners frequently praise strong pickup on carpet and reduced lingering hair. A few reports note limitations for long hair on upholstery or brush/belt strain in heavy pet homes.

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 usually rated positively for a bagged HEPA-style upright, with several reviewers calling it worth the money. Some disagree when durability or repair frequency becomes an issue.

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.

Some users describe a powered-assist or self-propel-like feel, while others explicitly wish it were self-propelled, especially as they age or when cleaning thick carpet.

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 supported via hose/tools and at least one stair-focused attachment mention, but carrying weight and hose tug can make stair work more demanding for some users.

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.

Several reviewers like the compact footprint and storage friendliness, especially for apartments and tight spaces. Upright stability is occasionally criticized due to wobble or center-of-gravity comments.

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.

Suction is consistently described as strong, often the primary reason people keep the vacuum. A minority say it is good but not on par with their best prior vacuum, or that strong suction can increase push effort.

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.

Support experiences are mixed but lean positive in key stories, including at least one report of a quick refund after failure. Others report difficulty reaching customer service or post-warranty parts frustration.

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.

Tool changes are usually straightforward, especially with the telescoping wand. Compatibility with older hoses or certain attachments is a reported pain point for some owners.

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.

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.

Above-floor cleaning is generally strong with the wand and crevice tool, but upholstery performance is mixed, including complaints about long pet hair on couches and limited included fabric tools.

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.

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 impressions vary but cluster around sturdy and somewhat heavy. Many say it feels fine while pushing, but heavier when carrying up stairs or doing repeated back-and-forth on thick carpet.

Wool and delicate rug compatibility is a concern in the reviews: some users report damage to a rug or needing to avoid edges, and others note wool rugs fill bags quickly even when they like the cleaning result.
