When the lower locking unit locks the connecting rod, the bottom of the suction nozzle is close to the ground, and at the moment, dirt such as hair on the ground is adsorbed by the suction nozzle; when the upper locking unit locks the connecting rod, the suction nozzle is far away from the ground, and the suction nozzle is in a non-working state.

The use of the invention is described below: when the invention is used, the rear cover plate is firstly opened, and tap water or sterilized water is injected into the water tank in the rear cavity; then the rocking handle is shaken to enable the cleaning wiper to be in contact with the ground; then the suction nozzle is put down to enable the suction nozzle to be close to the ground, the locking and fixing of the connecting rod are achieved through the locking unit, and the fan is started; and finally, the motor is started to enable the whole device to walk, and in the walking process of the right walking wheel, dirt such as hair on the ground is firstly adsorbed by the adsorption mechanism, and then the right walking wheel is cleaned and scrubbed to move continuously to scrub the ground. The cleaning wiper sequentially cleans the ground, receives cleaning of the cleaning roller and scrubbing of the scrubbing unit in the moving process, and the processes are continuously circulated, so that the device has a self-cleaning function.
