Automatic cleaning robot

Abstract

This invention relates to an automatic cleaning robot for cleaning surfaces with varying elevations. The robot body includes a control device mounted on top of the surface to be cleaned, and a cleaning displacement device connected to the control device and facing the bottom of the surface. The automatic cleaning robot primarily uses a breeding wheel in the cleaning displacement device to move the cleaning displacement device towards the bottom of the surface by gravity. During the movement, a roller brush in the cleaning displacement device cleans dust and dirt from the surface. When the cleaning displacement device reaches the bottom of the surface, a coil spring connecting the control device and the cleaning displacement device pulls the cleaning displacement device back to its original position.
