ROBOT CLEANING SYSTEM AND CONTROL METHOD THEREOF

A robot cleaning system includes a cleaning robot, and a base station. The cleaning robot includes: a main body, a mover, and a mopping module, movably connected to the main body and including a replaceable cleaning layer. When the mopping module is in the first state, the cleaning layer is fitted to the working surface, and when it is in the second state, the cleaning layer is separated from the working surface, so that a working surface of the cleaning layer is exposed and is in contact with a cleaning layer removal mechanism. The cleaning robot also includes a driving mechanism configured to drive the mopping module to switch between the first state and the second state; and a controller configured to at least control the driving mechanism to drive the mopping module to switch from the first state to the second state when the cleaning layer needs to be replaced.
