Transmission apparatus, automatic cleaning device and cleaning robot system

Abstract

The present disclosure provides a transmission apparatus, an automatic cleaning device and a cleaning robot system. The transmission apparatus comprises a first cleaning assembly (130) and a first driving assembly (132); the first cleaning assembly (130) comprises a rotating arm (1301) and a first cleaning element (133); and the first driving assembly (132) is used for driving the first cleaning element (133) to rotate, and the first cleaning element (133) abuts against a surface to be cleaned, so as to drive, by means of friction force, the first cleaning element (133) swinging along with the rotating arm (1301) to move from a first operation position to a second operation position in a second direction. Thus, the first driving assembly (132) drives the first cleaning element (133) to rotate, and the first cleaning element (133) abuts against the surface to be cleaned, so that the first cleaning element (133) is switched from the first operation position to the second operation position, and then the first cleaning element (133) is moved to an operation position meeting the requirements of a corresponding cleaning range.
