Take out the water tank, fill it with water, and put it back inside the robot cleaner.
Fill the water tank only with purified room temperature water to avoid a buildup of limescale from hard water. Do not use detergents or cleaners, as they may damage the water tank and the appliance.
To add water to the water tank or install the mopping module, pause the sweeping first. Do not move the robot cleaner manually.

Wet the mop pad and wring it out until it stops dripping. Install the mop pad along the slot of the holder and fix it tight.
Before attaching the mop, wet the mop with enough water and wring the mop.

Insert the mopping module into the bottom of the robot cleaner until you hear a click.
After inserting the mopping module, the robot cleaner will automatically switch to the mopping mode.

Select the sweeping mode to start sweeping.
The robot cleaner will automatically sweep and mop the floor in the selected mode.
Adjust the mopping water level in the APP according to needs.
To achieve better cleaning, let the robot cleaner sweep the floor 3 times and then install the mopping module.
If the mop pad is excessively wet, the floor may become slippery and cause people to slip.
Do not leave the robot cleaner in the home station or on the floor for a long time with wet mop pad attached. Doing so may cause floor damage or odours.
