How to Clean a Dyson WashG1 Wet Floor Cleaner

Step-by-step instructions

Step 1: Finish cleaning and run the self-clean cycle

Return the WashG1 to its hydration station with enough clean water for the cycle and follow the LCD prompt for self-cleaning. Let the program finish without moving the machine. Self-cleaning rinses the rollers and pathways, but it does not eliminate the need to empty the dirty tank and debris tray or to inspect hair at the roller ends.

Step 2: Power down before removing wet components

Switch the machine off and disconnect it from charging as the guide directs before opening the head. Keep the body upright on a protected hard floor. Do not touch electrical contacts with wet hands, tip wastewater toward the display, or attempt to remove a battery or internal pump during routine care.

Step 3: Empty and rinse the dirty-water tank

Release the dirty tank, remove its lid, and pour out the water. Dyson recommends regularly rinsing both water tanks and wiping them dry. Use warm water, mild detergent, and a soft cloth on the dirty tank when film is present. Remove the float from the lid counterclockwise only as shown, rinse it, and reinstall it in the correct orientation.

Step 4: Empty and clean the debris tray

Slide out the debris tray without dumping solids into the roller housing. Dispose of captured hair, grit, and food into the trash, then rinse and wipe the tray. Brush the mesh gently from the accessible side and clear its edges. Do not bend the screen or send large solids down a household drain.

Step 5: Remove the two microfiber rollers

Open the roller cover and release each roller by its documented end cap or tab. Note front and rear placement so they return to the correct sockets. Pull off loose hair and debris before washing, especially at the axles. Do not pour water into the exposed drive openings or force a jammed roller out at an angle.

Step 6: Hand-wash and squeeze the rollers

Dyson says to wash dirty rollers with warm water and detergent, rinse them, squeeze out excess water, and leave them to dry thoroughly. Work along each cylinder without twisting the core or pulling the microfiber pile. Continue rinsing until the water is clear and no detergent remains. Never use a washing machine, tumble dryer, or high heat.

Step 7: Wipe the roller housing and hydration points

Use a clean damp cloth on accessible wet surfaces, squeegee edges, and the hydration points that deliver water to the rollers. Lift out strands with fingers or a soft brush. Keep free water out of the drive sockets, motor housing, and connector. If a blockage is beyond normal access, use Dyson troubleshooting rather than inserting a wire.

Step 8: Rinse the clean-water tank and inspect the mesh

Empty long-stored water, rinse the clean tank, and wipe it dry. Inspect the filter mesh for mineral scale. Dyson's support guidance calls for limescale maintenance about every six months; follow the WR01 screen or owner guide for the exact descaling process rather than adding vinegar or another improvised chemical to the operating tank.

Step 9: Dry parts and clean the hydration station

Stand both rollers where air reaches all sides and leave the tank lids and debris tray separated. Wipe the hydration station and remove any pooled water or solids. Keep its charging interface dry. Do not reassemble merely because the roller surface feels dry; squeeze gently and check the ends for retained moisture.

Step 10: Reassemble and monitor roller life

Return each fully dry roller to its correct position, close the cover, refit the tray, float, and tanks, and confirm every latch. Dyson estimates roller life at around 25 operating hours depending on use and provides a lifetime counter in the LCD menu. Replace rollers that remain flattened, torn, odorous, or past their indicated life rather than compensating with extra detergent.
