Frequently asked questions

The Dyson Digital Slim Submarine™ wet and dry vacuum comes with Dyson’s Hair Screw Tool, which is designed to pick up long hair and pet hair with ease. Hair should be vacuumed up before using the Submarine wet roller head for the best cleaning result.

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

We suggest owners to wash the Submarine™ wet roller as well as the Submarine wet roller head, after every clean.

Slide the cassette out to empty the waste tray, which can also be washed and wiped down to remove more stubborn or viscous debris. Make sure you do this after every clean to maintain optimal hygiene. Clean the wet roller using water and a common household anti-bacterial detergent - Dilute as per manufacturers recommended ratio. Rinse the main roller head with running water and do not soak it in the water to protect motor

The Dyson Submarine™ wet roller head is not compatible with any of our other vacuums, including pre-purchased Digital Slim™. 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.

If you decide to use detergent, please choose common household anti-bacterial detergent and do not use bleach. Please follow the manufacturers guidance on the recommended dilution - we do not recommend putting neat detergents in the clean water tank. We recommend emptying the water tank with running water after each clean. If it is not in use every day, please allow the water tank and wet roller to dry 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.
