Cleaning robot system

Abstract

A cleaning robot system includes a self-moving cleaning device and a base station. The self-moving cleaning device includes a machine main body, a cleaning element and a movement mechanism. The movement mechanism is connected to the machine main body and the cleaning element to drive the cleaning element to be lifted and lowered relative to the machine main body. The cleaning element and the movement mechanism are detachably connected by means of a first magnetic attraction assembly. The cleaning element is provided with a first magnetically attractable part. The base station is provided with an electromagnet. A magnetic attraction force between the energized electromagnet and the first magnetically attractable part is greater than a difference between a magnetic attraction force of the first magnetic attraction assembly and a gravitational force of the cleaning element.
