Our Verdict

Shark Stratos Cordless IZ862H

Dyson Digital Slim

The Shark Stratos Cordless IZ862H is better than the Dyson Digital Slim in almost every way. It offers better performance on every surface type and is more feature-rich, with automatic suction adjustment and an odor-neutralizing cartridge that plugs into its floorhead. It also has better battery life and build quality. That said, the Dyson offers a more appealing interface with an LCD display that shows remaining battery life, alerts, and more.
