Abstract: Disclosed is a base station comprising a base and a liquid path system disposed on the base. The liquid path system may comprise a first device and a second device. The first device may be configured to perform a first treatment on water to form a first liquid, and the second device is configured to perform a second treatment on water to form a second liquid. The second liquid may be different from the first liquid in temperature and/or composition. The first device can provide the first liquid with a first function for a cleaning robot, and the second device can provide a second liquid with a second function for the cleaning robot, so that the base station can provide a variety of liquids with different functions for the cleaning robot to meet different floors, different environments, and different user needs.
