Quick verdict: Shark wins for modern bagless convenience, lightweight uprights, and hair-friendly brushrolls — it is the easier brand to buy for most homes. Kenmore wins for traditionalists who want bagged filtration, powerhouse uprights, and excellent bagged canister vacuums built on decades of Sears-era engineering. Pet owners with allergies will find a strong case for either: Shark for bagless ease, Kenmore for sealed bagged HEPA systems.
Brand overview: Shark
SharkNinja’s Shark division started in 1998 and built its reputation on aggressive suction, swivel steering, and the Lift-Away canister-in-upright design that turned heavy uprights into versatile cleaners. In 2026, Shark’s lineup leans hard into hair management: DuoClean PowerFins, self-cleaning brushrolls, and HairPro nozzles are designed specifically to defeat the hair wrap that plagues pet owners. Shark vacuums are almost all bagless, which keeps running costs low — you rinse a filter instead of buying bags.
Shark’s customer base skews toward busy families and pet owners who want to grab a vacuum, clean the whole house without swapping bags, and get back to their day. The Navigator line remains one of the best-selling vacuum families on Amazon year after year, while the Stratos and Vertex models push Shark into the premium upright segment that once belonged to Dyson.
Brand overview: Kenmore
Kenmore is one of America’s oldest appliance names, a Sears institution dating back to 1927, now licensed by Cleva North America. Where Shark chased bagless convenience, Kenmore doubled down on what its loyal buyers love: bagged systems with triple HEPA filtration certified by the Asthma and Allergy Foundation of America, big 12-amp motors, and genuinely capable canister vacuums. Kenmore’s bagged design means the dust, dander, and pet hair you pick up stays sealed in a disposable bag — a real advantage for allergy sufferers who hate emptying dusty bagless bins.
Kenmore’s catalog runs deep: the Elite 31150 bagged upright with its 12-amp 3D Inducer motor, the Elite 21814 CrossOver bagged canister with a motorized Pet PowerMate, and the 400 Series 81414 bagged canister with a two-motor system and a telescoping wand that reaches up to 9.5 feet. These are not fashion items; they are workhorse machines, heavier than Shark’s equivalents but built to clean deep pile carpet for years.

Head-to-head: cleaning performance
Hard floors: Shark’s DuoClean PowerFins models (Stratos, Vertex) are among the best hard-floor performers in the upright category — the soft front roller grabs fine dust that stiff brushrolls scatter. Kenmore’s canisters answer with a dedicated bare-floor tool and strong straight suction, and the bagged design means zero dust cloud when you empty it. Both are excellent; Shark is faster, Kenmore is tidier.
Carpet and pet hair: This is where the philosophies diverge. Shark’s self-cleaning brushroll and HairPro pet brush actively fight hair wrap, which makes the Stratos and Vertex genuinely low-maintenance for homes with shedding dogs. Kenmore’s 12-amp 3D Inducer motor on the 31150 upright pushes roughly 20% more power than Kenmore’s own standard uprights, and expert reviewers consistently praise Kenmore for deep carpet pickup — its canisters earned top marks for high-pile carpet in independent lab testing. If your home is mostly thick carpet, Kenmore’s raw power and motorized nozzles are hard to beat. If hair wrap is your nemesis, Shark’s anti-tangle engineering wins.
Filtration and allergies: Kenmore takes this round clearly. Triple HEPA filtration certified to capture 99.97% of debris down to 0.3 microns, inside a sealed bag you throw away without touching the dust — that is the gold standard for allergy households. Shark’s Complete Seal + HEPA system is good and the filters are washable, but emptying a bagless bin inevitably exposes you to a puff of dust.
Maneuverability and weight: Shark wins. Swivel steering and Lift-Away pods make Shark uprights feel nimble, and the Navigator NV360 is far lighter than the 26-pound Kenmore Elite 31150. Kenmore canisters mitigate the weight problem by letting the canister body follow you — the Elite 21814 is notably easy to steer despite its heft — but you are still dragging a canister.
Which brand is better for pet owners?
Both brands court pet owners hard, but they solve different problems. Shark solves the hair-wrap problem: self-cleaning brushrolls mean you are not cutting tangled hair off the brush every month. Its Pet Power Brush and pet tools are included with flagship models. Kenmore solves the dander problem: bagged HEPA containment means the allergens you vacuum stay captured, and the Pet Handi-Mate and motorized Pet PowerMate are purpose-built for stairs, upholstery, and embedded pet hair. For a deeper look at uprights built for shedding, see our guide to the best upright vacuums for pet hair.
Price and running costs
Shark is usually cheaper to run: no bags to buy, washable filters, and aggressive retail pricing on the Navigator line. Kenmore bags are an ongoing cost — budget for replacement bags (the 53292 Type Q style used across the 400 Series) and occasional HEPA filters. That said, Kenmore’s purchase prices are competitive: the 81414 400 Series canister frequently sells in the $176–$188 range, undercutting many Shark uprights while delivering a two-motor bagged system. Total cost of ownership over five years is roughly a wash for comparable tiers; Shark wins on convenience, Kenmore wins on containment.
Reliability and support
SharkNinja offers standard warranties and a large service network, and Shark vacuums consistently earn high review counts on Amazon — the Navigator line is a perennial best-seller. Kenmore’s current vacuums are made by Cleva North America, and while long-term durability data is thinner than in the Sears heyday, the 81414 carries a 4.1-star average across more than 13,000 Amazon ratings, which is a solid signal at this price. Both brands sell replacement parts and filters widely.
Our top picks
Best Shark for most people — Shark Navigator Lift-Away Deluxe (NV360): The classic. Lift-Away pod, HEPA filtration, swivel steering, and a price that rarely hurts. If you just want a dependable upright, start here.
Best Shark for pet hair — Shark Stratos (AZ3002): DuoClean PowerFins HairPro nozzle, Powered Lift-Away, self-cleaning brushroll, and Odor Neutralizer Technology. This is Shark’s answer to the hair-wrap problem, and it works.
Best Shark premium upright — Shark Vertex (AZ2002): DuoClean PowerFins with a self-cleaning brushroll and HEPA filtration in a Powered Lift-Away body. A strong step up from the Navigator for deep carpet homes.
Best Kenmore for deep carpet — Kenmore Elite 31150: The 12-amp 3D Inducer motor, triple HEPA filtration, 35-foot cord, and Pet Handi-Mate make this the Kenmore to buy for carpeted homes with pets. Heavy at 26 lbs, but nothing at this price cleans carpet quite like it.
Best Kenmore canister — Kenmore Elite 21814 CrossOver: Pet Friendly bagged canister with the motorized Pet PowerMate, extended telescoping wand, and retractable cord. Excellent on both carpet and hard floors.
Best Kenmore value — Kenmore 81414 (400 Series): Two-motor bagged canister with HEPA filtration, a 26-foot auto-retract cord, and a telescoping wand with 9.5 feet of reach — frequently available under $190. One of the best value canisters on the market.
Pros and cons
Shark
Pros: Lightweight and maneuverable; excellent anti-hair-wrap technology; bagless = no bag costs; washable filters; Lift-Away versatility; strong value pricing. Cons: Emptying the bin exposes you to dust; premium models are pricey; bagless bins need regular washing to avoid odor; less raw deep-carpet power than Kenmore’s 12-amp uprights.
Kenmore
Pros: Sealed bagged HEPA systems are ideal for allergies; powerful motors and two-motor canisters; excellent deep-carpet performance; competitive pricing, especially the 400 Series; long brand heritage. Cons: Heavier machines; ongoing bag costs; canister models require dragging a body unit; brand ownership changed hands (now Cleva), so long-term support is less certain than SharkNinja’s.
FAQ
Is Shark or Kenmore better for pet hair? Both excel, differently. Shark’s self-cleaning brushrolls prevent hair wrap, so maintenance is easier. Kenmore’s motorized pet tools and bagged HEPA containment capture more dander. If you hate cutting hair off brushrolls, pick Shark; if allergies are the bigger issue, pick Kenmore.
Are Kenmore vacuums still good in 2026? Yes. The current Kenmore vacuums, built by Cleva North America, carry the brand’s traditional strengths — bagged HEPA filtration and strong motors — and models like the 81414 canister hold 4.1-star averages across 13,000+ Amazon ratings.
Do Shark vacuums need bags? No. All the Shark models in this comparison are bagless. You empty a dust cup and rinse the washable filters, which keeps running costs near zero but means some dust exposure when emptying.
Which is quieter, Shark or Kenmore? Neither brand publishes standardized noise ratings for these models. In general, Kenmore’s canister models tend to run a bit quieter than its uprights because the motor sits in the canister body on the floor, while Shark’s uprights put the motor at handle height.
Can I use a Kenmore canister on hardwood floors? Absolutely — that is one of their strengths. Kenmore canisters ship with dedicated bare-floor tools, and the 81414 and 21814 handle the hard-floor-to-carpet transition easily. Shark’s DuoClean models are also excellent on hard floors.
Which brand offers better value under $200? Kenmore, at the moment. The 81414 400 Series canister frequently sells under $190 with a two-motor bagged HEPA system — tough to beat. Shark’s best sub-$200 pick is the Navigator NV360, which is also excellent but bagless and upright-only.
Final verdict
Buy Shark if you want a light, nimble, bagless vacuum with best-in-class hair-wrap resistance and near-zero running costs. The Navigator NV360 is the safe default; the Stratos AZ3002 is the pet-hair specialist.
Buy Kenmore if you want sealed bagged HEPA filtration for allergies, maximum deep-carpet cleaning power, or a genuinely good canister vacuum at a fair price. The Elite 31150 is the carpet king; the 81414 is the value champion.
For most American homes with mixed flooring and a pet or two, Shark’s convenience wins the day. For carpeted homes and allergy sufferers, Kenmore’s bagged system is the smarter long-term choice. The real decision is bagged vs bagless vacuums: sealed bags for allergies, bagless for low running costs.
