Cleaning systems and self-cleaning methods for cleaning devices

A cleaning system, comprising a cleaning device and a base station, wherein:

• the base station, when docked with the cleaning device, is used to control the cleaning device for self-cleaning and charging a rechargeable battery;
• the cleaning device includes:
• a clean water tank, for storing a cleaning liquid;
• a water pump, provided on a liquid supply path for pumping the cleaning liquid of the clean water tank out;
• a sewage tank, for storing dirt;
• a suction drive module, for providing a suction force for sucking the dirt into the sewage tank;
• the rechargeable battery, for powering the water pump as well as the suction drive module;
• a battery charging circuit, electrically connected to the rechargeable battery for controlling recharging of the rechargeable battery;
• and
• a cleaning part, for cleaning an object to be cleaned;
• the cleaning system further comprises a trigger control part and a control module, wherein
• the trigger control part is configured for activating a self-cleaning mode;
• and
• the control module is configured for:
• activating the self-cleaning mode and controlling the battery charging circuit to fail after receiving a trigger signal from the trigger control part;
• in response to monitoring a first predetermined state, controlling the battery charging circuit to be effective to charge the rechargeable battery during executing the self-cleaning mode to clean the cleaning part;
• in response to monitoring a second predetermined state after monitoring the first predetermined state, controlling the battery charging circuit to fail, continuing to execute the self-cleaning mode to clean the cleaning part, and exiting the self-cleaning mode until a self-cleaning completion condition is met;
• and
• wherein the self-cleaning mode includes:
• M times of a sub-self-cleaning mode;
• the control module is configured to execute the M times of the sub-self-cleaning mode;
• M being an integer greater than or equal to 1.
