The Submarine™ wet roller head motorises a micro‑fibre roller that washes spills, stains and dried‑on liquids from hard floors, continuously extracting dirt from the roller with each rotation.
A dust‑detect sensor counts particles up to 15,000 times per second, automatically adjusting suction power. An LCD screen displays real‑time feedback of particles removed, giving scientific proof of a deep clean.
The whole‑machine filtration captures 99.99 % of particles down to 0.3 µm. Dyson’s patented 11‑cyclone Root Cyclone™ system ensures no loss of suction.
The point‑and‑shoot mechanism ejects dust and debris into the bin in a single action, so you never touch the dirt.
Included tools – Fluffy Optic™, Motorbar™, Hair Screw, Combination, Crevice, Reach‑Under, Wand clip – tackle carpet, hard‑floor, pet‑hair and tight‑space cleaning. All tools are stored on a wall‑mounted dock for easy access.
Lightweight cordless design with a wall‑mounted Wall Dok™ dock for charging and tool storage. The vacuum’s LCD screen and sensor‑driven power management optimise performance and battery life.
