Disclosed are a cleaning robot (10) and a control method therefor. The method comprises: acquiring a marked position of a charging post in a map, wherein the map is a map drawn by the cleaning robot (10) (501); controlling the cleaning robot (10) such that the cleaning robot moves to a front position of the marked position to identify the charging post (502); if the charging post is not identified, generating a seeking path based on the marked position (503); and controlling the cleaning robot (10) such that the cleaning robot moves in accordance with the seeking path to identify the charging post in the moving process (504). The problem that a cleaning robot (10) cannot find a charging post and can not implement an action of returning back to the post when an actual position of the charging post is different from a marked position in a map is solved, and the effects of improving the intelligent degree of the cleaning robot (10) and reducing human intervention are achieved.
