Abstract: A base station includes a main body having a first accommodating space and a water inlet; a water supply assembly communicating with the water inlet to convey water for cleaning a cleaning robot to the water inlet; and a sewage discharge assembly including a sewage tank and a negative pressure generation unit. The negative pressure generation unit has an air extraction end generating a negative pressure and an air exhaust end generating a positive pressure. The air extraction end forms the negative pressure in the sewage tank. The air exhaust end communicates with the water inlet. Positive pressure gas conveyed by the air exhaust end flows out of the water inlet or is mixed with water conveyed by the water supply assembly to form a gas-liquid mixture having pressure greater than the pressure of the water supply assembly, and then the gas-liquid mixture flows out of the water inlet.
