Dyson V16 Piston Animal Submarine vs SharkNinja VS101 MessMaster

These are different tools, not close rivals. The Dyson V16 is a full cordless floor vacuum with a 315 AW motor, a 70-minute Eco run time, HEPA filtration and anti-tangle cones for carpet and pet hair. The Shark MessMaster is a small corded wet/dry canister built for spills, pet accidents and DIY messes, with a 1-gallon bin and a 20-foot cord. Buy the Dyson for whole-home dry cleaning; buy the Shark for liquids and gunk. Owners rate the Shark slightly higher (4.3 vs 4.1), but the Dyson sample is small at 25 ratings.

• Choose the Dyson V16 if you want one cordless machine for carpets, hard floors and pet hair across the whole house.
• Choose the Shark MessMaster if your messes are wet, small and nasty, and you want a corded canister that rinses itself.
