• terminating the forward movement in front of the moist area and rotating the appliance or robot about substantially 180°;
• driving on the moist area in a reversing movement relative to the direction of travel of the appliance or robot and mopping up the accumulation of liquid by using the wet cleaning module;
• placing a cleaning liquid supply of the wet cleaning module in an active mode in the forward movement in the direction of travel of the appliance or robot and in an inactive mode in the reversing movement relative to the direction of travel of the appliance or robot;
• moistening a mopping unit with cleaning liquid from a container unit in the active mode, stopping the moistening from the container unit during the reversing movement of the appliance or robot while in the inactive mode, and resuming a reactivation of the supply of cleaning liquid to the mopping unit after a predetermined time, depending on a size of the accumulation of liquid.
