Dyson and Shark are the two names most people consider when buying a cordless stick vacuum. Dyson is the premium brand known for powerful suction, laser-lit floor heads and high prices. Shark undercuts it with clever features like self-emptying docks and hands-free floor transitions. The question is whether Dyson’s extra power is worth the extra money.
This guide answers it. We compared TechGearLab’s lab testing of 20 cordless vacuums, updated October 21, 2026, with Trusted Reviews’ brand comparison and WIRED’s reviews. We haven’t tested these vacuums ourselves, and every figure is credited. List prices are TechGearLab’s and change.
The short answer: the Shark PowerDetect is TechGearLab’s pick for most people, at a $550 list price, and it’s better with pet hair on shag rugs. The Dyson V15 Detect, at a $750 list price, ties it on overall score and wins on hardwood, edges, tools and run time. Buy Dyson for maximum performance and Shark for value and convenience.

Cleaning performance
In TechGearLab’s tests, the Dysons led on hardwood. Their Fluffy Optic head picked up 99% of debris, and the laser that lights up fine dust is a feature testers ended up loving. The Shark PowerDetect picked up 97% on hardwood. On low-pile carpet, all three cleaned 94% or more. On high-pile shag, the Shark did better, clearing 54% against the V15’s 49%. TechGearLab explains that the Dysons’ strong suction slows them down on deep carpet, though extra passes help.
Trusted Reviews’ measurements point the same way. Dyson vacuums typically post higher AirWatts. The Dyson Piston Animal measured 401AW against 322AW for the Shark PowerDetect Speed Clean and Empty Pet Pro. Trusted Reviews also measured 99.8% versus 99.1% dust collection in its controlled test, and 99% versus 95.9% on edges. Both collected 100% on hard floors.
Pet hair
The Shark PowerDetect cleaned the most pet hair overall in TechGearLab’s test (79%), and especially excelled on shag (74%). TechGearLab notes hair tends to wrap around its rollers, though, so pet owners may need to clean the head more often. The Dyson V15 picked up most hair, with some longer strands wrapped on the roller, which is easy to free. Trusted Reviews says both brands’ anti-hair-wrap tech generally works well.
Edges and tools
TechGearLab found the Shark’s front bumper keeps it from reaching edges on head-on passes, which makes it less effective on stairs and under cabinets, and it has no motorized upholstery tool. The Dysons aced edge cleaning in several models and come with a quiver of attachments, including a motorized hair screw tool that TechGearLab’s testers loved for furniture and cars.
Battery life
TechGearLab measured the Dyson V15 Detect at 64 minutes on low but only 9 minutes on Boost. The Shark PowerDetect ran 47 minutes on low and 12 on max. In practice, TechGearLab found the V15’s Auto mode enough for most of a home. Trusted Reviews also found Dyson’s cordless batteries generally outlast Shark’s.
Ease of use
Shark wins on convenience. The PowerDetect’s self-emptying dock stores the vacuum and spares you messy bin emptying. Its folding wand reaches under furniture, and its combination brush roll moves between floors without swapping heads. TechGearLab’s biggest complaint about the V15 Detect is its trigger, which must be held for the entire clean and tired testers’ hands. The pricier Gen5detect replaces it with a button.
Price
Dyson is consistently pricier. Trusted Reviews notes Shark’s cheapest US vacuum starts at $69.99, while Dyson’s cheapest, the handheld Car+Boat, is $299.99. TechGearLab suggests watching for Dyson sales and says the V15 Detect performed nearly identically to the Gen5detect in its cleaning tests.

Filtration and allergies
TechGearLab measured fine-particle emissions with laser particle counters while vacuuming flour. Most models, including the Dysons and Shark PowerDetect, fell in the excellent range. The Gen5detect has a certified HEPA filter, and TechGearLab calls it suitable for allergy sufferers. TechGearLab also notes HEPA isn’t the only standard that matters, since some proprietary systems perform as well in real use. If anyone in your home has allergies, look for sealed filtration and a dock or bin design that limits dust when emptying.
Noise
TechGearLab measured both the Shark PowerDetect and the Dyson V15 Detect at 79 dBA, and the Gen5detect at 77 dBA. It found differences between models too small for most people to notice. None are quiet enough for nap time.
Dustbins and emptying
Stick vacuums have small bins: TechGearLab lists 0.7 liters for the PowerDetect and 0.8 liters for the V15 Detect. The Shark’s self-emptying dock is a real quality-of-life upgrade, because you empty the dock’s larger bin far less often. Trusted Reviews found Dyson’s eject mechanisms vary by model, with the V16 Piston Animal’s especially streamlined.
Cordless vs corded
Cordless sticks are perfect for frequent, quick cleanups, stairs and cars. TechGearLab notes most cordless models run 20 to 60 minutes per charge and recommends a compact upright or canister for prolonged cleaning on a budget, since plugging in gives cheaper access to more power. Many large homes use a cordless stick for daily cleaning and a robot for maintenance; see our Roborock vs Roomba guide.
Batteries and longevity
All the vacuums TechGearLab tested have detachable batteries, and extra packs extend cleaning time, though lithium-ion batteries can cost more than $100. TechGearLab says the Dysons are built with durable materials that have survived years in its homes and office, while it has longevity concerns about some budget brands. Register your vacuum, keep filters clean, and replace batteries when runtime drops.
How we researched this guide
We don’t run a test lab, so we built this guide from independent testing by TechGearLab, which says it has tested over 250 vacuums in the past decade, and Trusted Reviews, with WIRED’s reviews for context. Where they measured something, we report their numbers and credit them by name. Where sources disagreed, or a claim came only from a manufacturer, we say so. We also weighed long-term ownership factors that matter to luxury buyers: warranty terms, build quality, ease of care and how a product fits into a well-designed home. Prices quoted are as listed by reviewers or retailers at the time of their writing and will change, so check current listings before you buy.
Stairs, cars and upholstery
TechGearLab found the Shark PowerDetect light and narrow enough to use on stairs without converting it to a handheld, though its bumper limits edge pickup on each step. Dyson’s motorized mini tools make stairs, pet beds, upholstery and car interiors easier, and TechGearLab’s testers loved the V15 Detect’s hair screw tool for furniture. If you clean cars often, Dyson’s attachment kit is a real advantage.
Hard floors and rugs
If your home is mostly wood, stone or tile with a few low rugs, the Dyson’s dedicated hard-floor head is the standout. If you have deep shag or many rugs, TechGearLab’s results favor the Shark.
