1. A self-cleaning method of a self-moving cleaning robot, wherein the self-moving cleaning robot comprises a control system including a communication module for communicating with a user and/or a device external to the self-moving cleaning robot, a storage module for storing at least one parameter related to the operation of the self-moving cleaning robot, and a control module for controlling operation of the self-moving cleaning robot; the self-moving cleaning robot has a basic working mode in which the self-moving cleaning robot performs actions of spraying water on the ground and collecting sewage at the same time, and a self-cleaning mode in which the self-moving cleaning robot performs at least one self-cleaning action on one or more cleaning components; and when the self-moving cleaning robot needs to perform the self-cleaning action, the following steps are performed: controlling, by the control module, the self-moving cleaning robot from the basic working mode to enter the self-cleaning mode; performing, by the self-moving cleaning robot, the at least one self-cleaning action; and when at least one condition for ending the self-cleaning action is met, controlling, by the control module, the self-moving cleaning robot to exit the self-cleaning mode; wherein, controlling, by the control module, the self-moving cleaning robot from the basic working mode to enter the self-cleaning mode includes adjusting parameters related to the operation of the self-moving cleaning robot while substantially maintaining the basic working mode, and wherein performing, by the self-moving cleaning robot, the at least one self-cleaning action includes increasing a suction force and/or a water spray flow in the self-moving cleaning robot.
