Which is better for pet hair?

Both are sold for pet homes. The Shark's DuoClean Detect nozzle uses two brushrolls and claims stronger hair pickup, and it adds a Pet Multi-Tool in the box. The Dyson V8 Animal includes a motorized pet tool and is lighter to handle on stairs.

Which has longer battery life?

The Shark, by a wide margin. It runs up to 70 minutes in ECO mode; the Dyson V8 runs about 40 minutes on standard power and less in boost.

Is the Shark worth the extra money?

If you want HEPA filtration, a 5-year warranty and double the runtime, yes. If you mainly vacuum hard floors in a small home, the lighter, cheaper Dyson V8 does the job.

Which is easier to carry upstairs?

The Dyson V8 at 6 lbs is about 2 lbs lighter than the 8.2 lb Shark. That matters on stairs and overhead cleaning.

Do both filter fine dust?

Both use HEPA-grade filtration. The Shark is HEPA-certified with washable foam and felt pre-filters plus a post-motor HEPA filter. Dyson V8 Animal models use whole-machine HEPA filtration.

How often do I empty the dust cup?

The Shark holds 0.7 qt and the Dyson V8 holds 0.14 gal, about 0.56 qt. Expect to empty the Dyson more often in a pet home.

Shark PowerDetect Cordless vs Dyson V8 Animal Cordless Stick Vacuum

Buy the Shark PowerDetect if you want the longest runtime, HEPA filtration and a 5-year warranty. Buy the Dyson V8 Animal if you want a lighter vacuum at a lower price and trust a long track record. The Shark is $329.99 at Home Depot as of November 7, 2026, and has swung between $279.99 and $475.00 since November 1. The Dyson V8 Animal is the cheaper, lighter pick, but the Shark wins on battery life, filtration and warranty.
