Our Verdict

Dyson V15 Detect

Shark Detect Pro IW3511

The Dyson V15 Detect is better than the Shark Detect Pro IW3511. The Dyson is considerably more powerful, delivers better performance on bare floors and carpets, and has a wider array of attachments. That said, the Shark is lighter and is only available with a self-empty docking station.
