Which is better for pet hair?

Both handle pet hair. The Dyson's Digital Motorbar head has anti-tangle technology that removes wrapped hair as you clean. The Shark's DuoClean Detect nozzle uses two brushrolls for strong hair pickup and comes with a Pet Multi-Tool.

Which is better for allergies?

The Dyson. It has fully sealed whole-machine HEPA filtration rated to trap 99.99% of microscopic dust and allergens. The Shark has a post-motor HEPA filter, but its pre-motor filtration is washable foam, not a sealed system.

Is the Dyson worth the extra money?

Only if sealed HEPA filtration and the laser hard-floor head matter to you. Otherwise the Shark costs about $115 less at the best new price and adds a 5-year warranty, a bigger bin and a bending wand.

Which has longer battery life?

The Shark, at up to 70 minutes in Eco mode. Dyson states up to 60 minutes of fade-free runtime in the description, though the spec sheet lists 120 minutes. Both figures are best-case, not on max power.

Which is easier to use under furniture?

The Shark. Its MultiFLEX wand bends to reach under low furniture and folds for storage. The Dyson uses a standard wand and relies on the handheld conversion for tight spots.

Which holds more dirt?

The Shark, with a 0.7 qt dust cup. The Dyson holds 0.2 gal, about 0.8 qt by conversion, but its listed capacity is smaller in practice and it empties point-and-shoot.

Dyson V15 Detect Cordless Vacuum vs Shark PowerDetect Cordless

The Shark PowerDetect is the better buy for most people: it costs about $115 less at the best new price ($205.00 at eBay versus $319.99 at Walmart, both as of November 4, 2026), has a bigger dust cup, a 5-year warranty and a wand that bends under furniture. The Dyson V15 Detect wins on filtration and hard-floor proof: sealed HEPA and a laser head that shows dust you can't see. Buy the Dyson if allergies or hard floors matter most; buy the Shark if you want more vacuum for less money.

Today the Dyson V15 Detect Cordless Vacuum costs $9.01 less at its best price.
