Most reviews mention a useful kit including a 3-in-1 combo tool (crevice/dusting/upholstery) plus a powered or rotating pet handymate tool for stairs and furniture.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.

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.
Airflow blowback
P1Product 1: Kenmore Bagless Upright Vacuum Lift
No score yet
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Area Rug Handling
P1Product 1: Kenmore Bagless Upright Vacuum Lift
No score yet
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Assembly and Setup
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.4
Assembly/setup is described as straightforward in an unboxing-style review, with quick connections for wand and hose and minimal fuss.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
4.8
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.
Bin and Bag
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.2
The bin is described as adequately sized and easy to remove, with users noting it can capture surprising amounts even after a recent cleaning with another vacuum.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Build quality and durability
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
2.8
Build quality impressions are mixed: several reviewers describe the unit as solid and well-built for the price, but at least one owner reports cracked hose components.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Carpet — High-Pile Pickup
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
3.8
High-pile performance is described as good but more situational; at least one user notes using the brushroll on very high pile despite some carpet guidance against it.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Carpet — Low-Pile Pickup
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.4
Low-pile carpet pickup is consistently rated strong, with lab-style tests and user demos showing thorough debris removal.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Carpet — Medium-Pile Pickup
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.5
Medium-pile pickup is a standout, including at least one report of a 100% deep-clean style test and other tests in the high-90% range.

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.
Comparative performance
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.4
In head-to-head comparisons, reviewers often rank Kenmore favorably versus similarly priced uprights for suction, usability, and pickup, while conceding competitors may offer longer warranties or different conveniences.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Controls and UI
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.2
Controls are generally simple and intuitive, including floor-type switching on some models and suction-control vents on the hose/wand in at least one review.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.4
Cord length is repeatedly called out as generous (around 30 ft), improving room-to-room reach without frequent outlet changes.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Cord management
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
3.4
Cord management is functional but not premium; wrapping is often manual, and retractable-cord convenience is referenced as a feature competitors may offer instead.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Crevice / Groove Pickup (Hard Floors)
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
3.4
Crevice/groove pickup is a reported weak spot on some versions, tied to design choices that reduce sealing at the floor for better large-debris intake.

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
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.4
Ease of use is repeatedly framed as a highlight due to swivel steering, lift-up/away versatility, and simple emptying, with only under-bed access and weight as recurring friction points.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Edge and Baseboard Cleaning (Hard Floors)

No score yet
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Emptying and Mess Control
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.5
Emptying is commonly described as quick and low-effort with push-button release, though routine upkeep (filters/brushroll) matters for maintaining performance.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Filtration / Dust Containment
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.5
Multiple testers call out a sealed HEPA air path that keeps fine dust and allergens contained, and smoke/leakage style tests are reported as passing well for the price tier.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Floorhead design
P1Product 1: Kenmore Bagless Upright Vacuum Lift
No score yet
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Hair Pickup — Carpets
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.3
On carpet, testers report very high pickup performance (often high-90% results) and strong pet hair removal, especially in medium/low pile situations.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Hair Pickup — Hard Floors
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.3
Hard-floor hair pickup is generally described as effective, helped by strong airflow and floorhead design; some versions emphasize better performance than similarly priced rivals.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Hair‑Wrap / Tangle Resistance
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
3.6
Tangle resistance is mixed: some tests show hair wrapping on the brushroll (especially longer hair), while other variants include hair-eliminator features that reduce buildup.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Hard Floor — Fine Dust Pickup
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.3
Fine dust pickup on hard floors is described as above average, supported by strong suction/airflow measurements and visible debris capture with headlights.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Hard Floor — Large Debris Intake
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.3
Large debris intake is noted as unusually capable on some variants due to wider front gates, improving chunky pickup versus many uprights at similar prices.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Headlight and LED lights
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.1
LED headlights are mentioned as genuinely helpful for spotting debris in darker areas and along typical cleaning paths.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Hose length
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
1.8
Hose durability is specifically criticized in one report that mentions cracking and snapping, suggesting the hose can be a weak point if stressed or used heavily.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Maintenance requirements
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
3.6
Maintenance is emphasized for bagless performance: multiple reviews mention regular filter cleaning and occasional brushroll hair removal, with outcomes (tangles, suction consistency) improving when upkeep is done.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Maneuverability and Handling
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.2
Handling is generally praised with responsive swivel steering and easy navigation around furniture, though the weight can still feel cumbersome for carries.
P2Product 2: Shark NV151 Navigator Swivel Pro...
No score yetNoise level
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
3.3
Noise is commonly described as loud for a corded upright, with test numbers around the high-70 dB range and user notes that it can be noticeable at higher power.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Odor control

No score yet
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Onboard tool storage
P1Product 1: Kenmore Bagless Upright Vacuum Lift
No score yet
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Ongoing ownership costs (bags, filters, batteries)
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
2.0
Ongoing costs come up mainly via filters, with one complaint that replacements feel expensive; multiple reviewers stress routine filter cleaning to preserve bagless performance.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Overall durability/longevity
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
1.5
Durability/longevity is the most polarized theme: some short-term impressions are positive, while a negative owner report describes early motor failure within months.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Overall opinion
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
3.5
Overall sentiment skews positive in test-focused and owner demo reviews, but there is at least one strongly negative experience centered on early failure and repairability.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.2
Pet capability is repeatedly highlighted via the included pet tool and strong carpet pickup, though brushroll hair management varies by model and user cleaning habits.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Price and Value
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
3.9
Value is a consistent strength: reviews frame these Kenmore uprights as delivering near-premium pickup and sealed HEPA features at a notably lower price.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Scratch resistance
P1Product 1: Kenmore Bagless Upright Vacuum Lift
No score yet
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Stair Cleaning
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.3
Stair cleaning is a strong use case when leveraging lift-up/away mode and the pet tool, making the weight less of a barrier than a traditional full-unit carry.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Storage footprint and upright-stand stability
P1Product 1: Kenmore Bagless Upright Vacuum Lift
No score yet
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Suction and Airflow
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.5
Across reviews, Kenmore’s Lift bagless uprights are described as very strong for a corded upright, with suction readings around the low-20 kPa range in testing and noticeably aggressive pull on carpet in home use.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Suitability for heavy-duty use
P1Product 1: Kenmore Bagless Upright Vacuum Lift
No score yet
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Suitability for small spaces
P1Product 1: Kenmore Bagless Upright Vacuum Lift
No score yet
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Support and Reliability
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
2.8
Reliability and warranty confidence is mixed, with comparisons noting shorter warranty terms than some competitors and at least one report of repeated shutdown/no-power issues.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Tool-change simplicity
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.2
Tool changes are described as easy, with combo tools that switch modes quickly and attachments that lock into place without much effort.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
4.5
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.
Under-Furniture Pickup
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
3.7
Under-furniture access is a common tradeoff: the main head may not fit under low beds, but lift-up/away plus hose/tools can partially compensate.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Upholstery / Above-Floor Pickup
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
4.2
Above-floor performance is supported by long reach wands and the included tools, with upholstery and ceiling reach called out as practical benefits.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Versatility
P1Product 1: Kenmore Bagless Upright Vacuum Lift
No score yet
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
Weight
P1
Product 1: Kenmore Bagless Upright Vacuum Lift
3.6
Weight is consistently in the mid-teens (about 14–15 lb), which is manageable for a corded upright but noticeably heavier than cordless options.
P2
Product 2: Shark NV151 Navigator Swivel Pro...
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.
