Compare Shark Rotator Powered Lift-Away Upright Vacuum, NV752 vs Kenmore Intuition Bagged Upright Vacuum

Longevity evidence is mixed-positive, with warranty praise and several long-term owner reports balanced against isolated failures.

Durability and longevity evidence was limited but strongly negative from the technician review, which said the machine did not meet older Kenmore quality standards.

Crevice and grouted-floor pickup has negative customer evidence, especially on grouted tile where grit required repeated passes.

Crevice pickup evidence was very positive in Vacuum Wars, where Kenmore performed significantly better than the Shark.

Tool changes are generally easy, with click-on accessories and a removable handheld piece praised for quick transitions.

Tool-change evidence was negative in the technician review, where a non-locking attachment came off during use.

Heavy-duty suitability is favorable, with professional and customer reviewers describing it as appropriate for pets, kids, carpets, and cleaning-house use.

Heavy-duty suitability evidence was negative from the technician review, which said the narrow path and design were not meant for a full house.

Under-furniture pickup is a major advantage because Powered Lift-Away lets the head or wand reach under beds and furniture.

Under-furniture pickup was a weakness because the dust-bin position, bulky body, and bed clearance limited reach.

Low-profile reach is praised when the detachable head or wand gets under beds, chairs, and furniture.

Low-profile cleaning was weak because reviewers said the bin and bulky body made cleaning under furniture difficult.

Build quality is mixed: professional reviewers often call it solid, while some customers report flimsy parts, broken lids, or cheaper-feeling plastics.

Build-quality evidence was strongly negative in the technician review, which called the quality unacceptable at higher prices.

Maintenance is generally easy for filters and dust-bin cleaning, but brush-roll hair maintenance can be frustrating for pet owners.

Maintenance evidence was mixed-to-negative, mainly because the wand, bag mechanism, cord hook, and brushroll required extra effort.

Small-space usefulness is positive when using the portable pod and tools for stairs, pantries, and tight spaces.

Small-space suitability was mixed: one technician saw it as more apartment or condo sized, yet also said the design still did not make sense for his own apartments.

Clogging evidence is mixed-negative: one CNET test found large carpet debris did not clog, but pet-hair and head-clog complaints recur elsewhere.

Clogging and debris-prevention evidence centered on the BU4050 hair eliminator, which was praised for tackling hair accumulation.

Hair pickup on carpets is a strength across tests and customer reviews, with many reviewers saying it pulls up pet hair effectively.

Carpet hair pickup ranged from good in Top Ten Reviews to mediocre or roller-sticking in TechGearLab and the technician review.

Ownership costs are favorable where discussed because the vacuum is bagless with washable filters and little routine replacement.

Ownership cost evidence was mixed: bags and filters add recurring expense, but one technician argued bagged machines can cost less to run than bagless designs.

Weight is a repeated drawback, with reviewers calling the unit hefty, heavy on the wrist, or difficult for some users.

Weight evidence depended on model and context: several reviewers called the BU4020/BU4022 light, while older or loaded variants were described as heavy or heftier than expected.

Floorhead design is mixed: it helps carpet pickup and maneuverability, but its lip and size cause hard-floor and width complaints.

Floorhead design evidence was negative in the technician review, mainly because the cleaning path was narrower than most vacuums.

Onboard tool storage is a weakness because the vacuum cannot hold all attachments and tools can fall or require the bag.

Onboard tool storage was mixed: some reviews liked organized onboard storage, while the technician review said tools did not lock in and bumped off.

Reliability and support are mixed: one review praises the long warranty, while a customer describes a poor warranty/support experience.

Support evidence was split between praise for a five-year warranty in BU4020/BU4022 coverage and criticism of a one-year warranty in the 31140 review.

Hose length is mixed to negative: one reviewer measured useful reach, but others say the hose is short and limits range.

Reach evidence was mixed: some reviewers liked the longer wand or hose, while the technician review strongly criticized the short, stiff hose.

Debris illumination is a standout practical feature, with users saying the lights reveal crud and missed dirt.

Debris illumination was praised where reviewers said the LED lights made dust, brush area, or hard-to-see debris easier to spot.

Low-pile carpet performance is broadly positive, though heavy debris can require extra passes.

Low-pile and general carpet pickup was a clear strength, with lab and tester evidence showing high collection rates and single-pass debris pickup.

Cord length is mixed: some reviewers call it long, while customers often want several more feet.

Cord length was generally considered good, often around 30 feet, though one technician found the usable cord length closer to 25 feet with the holder attached.

Hard-floor hair pickup is mixed, with one test favoring the Shark over Bissell and CNET/customer evidence showing weakness without the right tool.

Hard-floor hair pickup evidence was average, with TechGearLab saying it pulled up a fair amount but did not dominate the pet-hair test.

Upholstery and above-floor cleaning are generally good with pet and upholstery tools, but some reviewers find the pet tool weak or prone to resistance.

Above-floor and upholstery evidence was generally strong, with lift-up use and upholstery tools praised for stairs, sofas, and pet hair.

High-pile carpet performance is positive in review and customer evidence, with suction and settings helping rugs and high-pile carpet.

High-pile carpet pickup was strong in TechGearLab testing, with an outstanding average and easy pushing.

Airflow blowback is positively addressed in customer evidence where the Shark avoids spitting debris back at the user.

Airflow blowback evidence was positive in one technician test because the front exhaust did not blow pet hair away.

Stair cleaning is a consistent benefit because Lift-Away mode and attachments make stairs easier than with a fixed upright.

Stair-cleaning evidence was split: lift-up designs were praised for stairs by several reviewers, while the technician review found the hose and balance awkward enough to feel risky.

Large-debris hard-floor intake is mixed, with strong customer pellet pickup but CNET criticism that Cheerios were too tall for the head.

Large-debris hard-floor intake was mixed, with bigger gates and hard-floor pickup praised by Vacuum Wars but snowplowing and dragged debris noted in other tests.

Controls are praised for being on the handle and intuitive, though isolated customer feedback says the power button can be hard to keep engaged.

Controls were praised for practical brushroll and wand/lift controls that make switching modes straightforward.

Upright stability is a weakness in customer feedback, especially when the pod or wand is used and the unit tips easily.

Upright stability evidence was negative in the technician review because tugging the short hose could tip or move the machine.

The accessory package is valued for crevice, upholstery, pet, dusting, and hard-floor tools, though some customers wished more tools were included or stored onboard.

Most reviewers liked the included accessories, especially turbo, pet, upholstery, and combination tools, but the technician review criticized the tools as an afterthought.

Medium-pile or shag-style rug feedback is positive in customer evidence, with one user saying it revived a mid-cut shag area rug.

Medium-pile carpet evidence was excellent, including perfect deep-clean scores and strong user praise for deep cleaning.

The Lift-Away/convertible design is one of the product’s core strengths, making it easier to use as an upright, pod, canister-like, or handheld-style cleaner.

The lift-up or lift-away pod design was widely praised for above-floor cleaning, though the technician review felt it served little practical purpose.

Fine-dust hard-floor pickup is split: CNET found excellent sand pickup, while other reviewers and customers mention fine-particle or bare-floor weaknesses.

Fine-dust hard-floor pickup was mixed: some reviews praised hard-floor debris pickup, while Forbes and TechGearLab said hard floors lagged carpets and fine flour was challenging.

Edge and baseboard cleaning is mostly positive, though one review notes some debris may remain in corners or along walls.

Edge and baseboard hard-floor evidence was decent but not perfect, with one lab review saying head-on wall pickup worked better than parallel passes.

Filtration is one of the strongest consensus points, with sealed HEPA performance and smoke-test results keeping dust and allergens contained.

Filtration was one of the strongest themes, with sealed HEPA-style bags and lower dust exposure praised, though the technician review questioned the small exhaust filter.

Hair-removal channel and brush-cleaning access are notable weaknesses for long pet hair, with owners reporting lengthy brush-head cleaning.

Hair-removal maintenance was a recurring weakness because the brushroll did not pop out and was hard to clean.

Comparative performance is strong overall, with reviewers often favoring the NV752 over similarly priced uprights while noting pricier models can beat it in some tests.

Comparative evidence was positive in Vacuum Wars, where Kenmore beat the compared Shark in head airflow and pickup tests.

Pet performance is a major strength in most sources, with reviewers praising pet-hair pickup, though tool and tangle issues appear in some use cases.

Pet-focused evidence was mostly positive, with reviewers praising pet-hair pickup and allergy-friendly use, though separate hair-wrap evidence shows pet hair can still collect in the roller on some models.

Value is a strong theme: reviewers repeatedly say the Shark delivers high-end flexibility and suction for a midrange or reasonable price.

Value evidence was generally positive because reviewers saw strong carpet performance and extras for the price, but recurring costs and higher-price build concerns tempered the score.

Overall opinion is strongly positive across professional and customer sources, with caveats around hard floors, weight, hose length, and tangles.

Overall opinion was mostly favorable for carpet-focused buyers, value, and filtration, though the technician review was sharply negative about design and build tradeoffs.

Dust-bin feedback is mixed: reviewers like easy emptying and size in some tests, while Amazon customers complain the usable capacity can feel low.

The bag system earned praise for capacity, dust control, and allergy usefulness, but the technician review argued the bag size and sealing lagged competitors.

Design impressions are mostly positive, with reviewers noting modern styling, appealing color, and a premium-looking finish.

Design comments were generally positive, with reviewers noting rose-gold styling, a sleek package, and chrome accents.

Noise feedback is moderate: one reviewer found it quieter than a Dyson DC65 but not truly quiet overall.

Noise evidence was mixed: Consumer Reports described it as less noisy than the Oreck but still middle-of-the-road, Top Ten Reviews found it surprisingly quiet for its size, and one technician called it a screamer.

Maneuverability is generally good thanks to swivel steering, but the top-heavy pod and strong pull make handling mixed for some users.

Handling evidence was mixed: many reviews praised lightness, swivel steering, and obstacle-course movement, while heavier variants and stair carrying drew criticism.

Headlights are strongly praised for showing debris on floors, dark corners, and attachment work.

LED headlights were consistently praised as useful for spotting debris and lighting the brush area.

Emptying is usually praised as easy and mess-controlled, though bin capacity and packed pet hair create some complaints.

Emptying and mess control was mostly praised for dust-free, no-touch bag disposal, but one technician said the bag did not seal up well.

Cord management is a downside because the cord is manual, non-retractable, and can get in the way.

Cord management evidence was negative, with Vacuum Wars criticizing the stiff cord hook.

Innovation is tied to Powered Lift-Away; reviewers and customers describe the configuration as unusually flexible compared with other uprights.

Innovation evidence was positive but mostly feature-oriented, with no-touch bagging and uncommon features for the price presented as differentiators.

Area-rug handling is mixed: settings help some rugs, but several customers say suction is too strong for smaller rugs.

Area-rug handling was mixed: reviewers praised rug cleaning, but thick carpet and shag rugs could be hard to push or struggle.

Versatility is a standout strength, with reviewers praising the ability to clean floors, stairs, furniture, cars, corners, and under-furniture areas.

Versatility was a major strength, with reviewers praising lift-off use, wand reach, mixed-surface cleaning, and broad cleaning roles.

Hair-wrap resistance is one of the most mixed attributes: some reviewers report minor tangles, while pet-hair tests and long-hair owners report serious wrapping.

Hair-wrap evidence was the most consistent concern, with multiple reviews reporting tangles, wrapped long hair, or pet hair stuck around the roller.

Reviewers consistently describe the NV752 as a strong-suction corded upright with high airflow, especially through the hose and on carpets.

Reviewers repeatedly praised strong suction and airflow, especially on carpet, though one older-model review framed the power as part of broader cleaning performance rather than flawless all-surface results.

Ease of use is mostly strong thanks to Lift-Away, handle controls, and easy emptying, but weight and hose issues create exceptions.

Ease of use was generally strong, with reviewers praising pushability and simple operation, although some mechanisms needed getting used to.

Assembly and setup are praised as easy, with convenient clips and customer comments that it is simple to put together.

Assembly evidence was positive, with reviewers describing parts that lock in and quick setup from unpacking to full assembly.

Automatic obstruction shutoff has positive customer evidence because it protects the motor and warns when the brush stops or clogs.

Automatic brush/standby behavior is praised where mentioned, with the roller stopping when upright or locked.

The bag-full indicator was consistently liked as a helpful touch that prevents overfilling or unnecessary checking.

Dual-motor evidence was limited to one review, which credited the system with effective cleaning performance.

Hard-floor seal and intake are weak in some evidence, especially where the head struggles with large debris or sounds rough on hard floors.

Packaging has limited but positive customer evidence, with one buyer saying it was packed well and worked as described.

Surface safety is generally positive where addressed, especially brush-roll shutoff and soft hard-floor use, though some hard-floor concerns remain.

The self-propelled feel helps carpet cleaning for many users, though the pull can feel too strong in tight spaces.
