[0003] In the prior art, in order to enable the automatic swimming pool cleaning machine to automatically adjust the gravity center and the buoyancy center, enable the automatic swimming pool cleaning machine to walk according to the specified cleaning route, and improve the movement stability of the automatic swimming pool cleaning machine, a handle is used to adjust the balance of the automatic swimming pool cleaning machine, the handle plays the balancing role of the buoyancy when the automatic swimming pool cleaning machine moves, and the stable state of the cleaning machine can be maintained when the automatic swimming pool cleaning machine runs on the pool bottom or the pool wall.
[0004] Patent No. CN111757832B discloses an underwater cleaning robot, which comprises a machine body and a handle arranged on the machine body. When the underwater cleaning robot is working on the water bottom and / or climbing a wall underwater, the handle can float relative to the machine body under the action of buoyancy. A first side of the machine body is provided with a first through hole in the shape of a racetrack circle. A first rotating shaft is arranged in the first through hole in sliding and rotating connection with the first through hole.
