Emptying the Dirty water tank and the Debris tray

The LCD screen alerts you when the Dirty water tank is full. And our hygienic no-touch disposal lets you simply pour away the dirty water, then empty any Debris tray contents straight into the bin.

Deep cleaning and maintenance

Washing the water tanks

Regularly rinse both dirty and clean water tanks, and dry with a cloth. The smooth inner surfaces make cleaning easy and reduce dirt build-up.

Cleaning the Debris tray

Stones or other small debris may become trapped. If this occurs, remove by following these simple steps.

And to remove any limescale, we recommend cleaning the filter mesh every six months.

  • A user's hand lifting the red inner section away from the outer shell of the Debris tray

    1. Remove the red inner section

    Check for trapped debris in the small crevices on each side of the red surface, and remove.

  • A user rinsing the red inner section under a running tap

    2. Rinse under a tap

    After removing trapped debris, rinse both inner and outer parts of the Debris tray under a tap.

    3. Dry thoroughly

    Wipe both parts with a cloth to remove any remaining debris and excess water. Dry thoroughly before reassembling into the cleaner head.

Washing the microfibre rollers

After every few uses, check the rollers. If there's any debris, it's time to wash your rollers manually:

Remove debris, wash rollers with warm water and detergent. Rinse and squeeze to remove excess water, and leave to dry thoroughly before use.

Dyson WashG1™ wet floor cleaner has counter-rotating motorised rollers – instead of vacuum suction – to separate large debris from liquids. Vacuum motors may also expel air back into the room which could cause odours. It also has a unique separation system where secondary brush bars with nylon bristles remove large debris and hair from the rollers – while extraction plates squeeze off moisture. Debris collects in a removable tray, and waste liquid is pumped into a separate Dirty water tank.

It can clean everything from fine dust, small debris and hair, to splashes and spillages, all the way to heavier spillages such as ketchup, syrup and oil mist – even stubborn stains such as dried food and toothpaste.

When using floor cleaning solutions, do use gentle, low-foaming common household detergents and do not use bleach. Be sure to follow the solution’s specific direction for dilution - with a 1L clean water tank you shouldn't require any more than 1Tbsp of solution. We also recommend adding the solution after filling the clean water tank.
