Submarine™ wet roller head

New technology

Washes hard floors with clean water from start to finish

Motorised wet roller picks up liquids, debris and tough stains, which are continuously extracted from the roller with each rotation.

  • Hydrates

    8 precise hydration points evenly distribute clean water across the roller for full-width washing.

  • Absorbs

    Motor-powered wet roller spins 900 times a minute to absorb spills and dried-on stains from hard floors.

  • Extracts

    Extraction plate removes debris into the waste tray, so it's not transferred back onto your floor.


Wash hard floors all around your home

Engineered to clean tile, stone, wood, ceramic, vinyl, linoleum and laminate floors.


Frequently asked questions

The wet roller can be washed with a common household anti-bacterial detergent, diluted according to the manufacturer's recommended ratio. We recommend doing this after each clean to maintain hygiene.

Only the Dyson Submarine™ wet roller head should be used to pick up wet debris and liquid spills. Engineered with intelligent power diversion and mode detection, all aspects of wet cleaning are contained within the wet roller head. Water and debris is extracted from the roller into the waste tray, which sits directly behind the wet roller using Dyson’s new wet technologies.

The Dyson Submarine™ wet roller head is not compatible with any of our other vacuums, including pre-purchased V12. To intelligently switch between wet and dry cleaning, this version of the machine has been reprogrammed. Our previous software is not compatible with wet floor cleaning.

The Dyson Submarine™ wet roller head has been engineered for hard floors.

We recommend replacing the wet roller every six months, depending on how often you use your machine, to help maintain optimum performance.

Whilst not necessary for cleaning performance, we understand that some users will want to combine a cleaning detergent with the wet roller head. If you decide to use detergent, please follow the manufacturers guidance on the recommended dilution. We do not recommend putting neat detergents in the clean water tank.

Functions and capability


I bought this unit to replace the old one I had and it was good to upgrade as it is much stronger than my v11. It has more features and better as it keeps the house cleaner.
