[0007] Preferably, the cleaning unit comprises: a No. 1 telescopic rod, the No. 1 telescopic rod is fixedly installed on the top of one side of the receiving frame, and the top of the No. 1 telescopic rod is fixedly connected with a fixing clamp; a No. 1 block, the inner wall of the receiving frame is fixedly connected with the No. 1 block, the top of the No. 1 block is rotatably connected with the No. 1 shaft, and the top of the No. 1 shaft is fixedly connected with a driving wheel; a driving motor is fixedly arranged inside the No. 1 block, and the No. 1 shaft is fixedly connected to the output shaft of the driving motor; a toggle rod, the top of the driving wheel is fixedly connected with the No. 2 shaft, and a plurality of toggle rods are fixedly arranged on the No. 2 shaft, and the toggle rods are circumferentially distributed from top to bottom on the No. 2 shaft;

[0008] The fixed bracket is clamped on the wall on the roof, and the driving motor rotates to drive the driving wheel to rotate. The driving wheel fits the wall and rubs against the wall, so that the receiving frame moves along the wall. During the movement, the No. 2 axis rotates, driving the toggle rod to rotate, and the loose cement blocks, bricks, tiles, etc. are pushed down and fall into the receiving frame. The extension and retraction of the No. 1 telescopic rod allows the toggle rod to move to different heights on the wall.
