Take out the dustbin and water tank.

Take out the dustbin.

Remove the Water Inlet cap and fill the water tank from a filtered or potable water source. Do not use other liquids or chemicals as they can cause property damage and product malfunction.

Re-install the dustbin and water tank in place.

Install the mop on the mop holder.
Before attaching the mop, wet the mop with enough water and wring the mop.

Insert the mop holder into the bottom of the robot cleaner until you hear a click.

If the mop 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 attached. Doing so may cause floor damage or odours.
