The wet roller can be washed with a 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.

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.
