Window cleaning robot

The invention discloses a window cleaning robot. The window cleaning robot comprises a base, a baffle movably arranged on the base, and a detection component comprising a first conductive part and a second conductive part, wherein the first conductive part is fixedly arranged on the base, the second conductive part is fixedly arranged on the baffle, the first conductive part is opposite to the second conductive part, and the second conductive part is driven by the baffle to move between the conduction position in touch with the first conductive part and the off position separated from the first conductive part. According to the window cleaning robot, the collision position can be judged through the connection and disconnection condition of the first conductive part and the second conductive part, so that corresponding avoiding measures can be taken.
