Abstract

The present disclosure relates to the field of smart home technologies, and proposes a base station and a cleaning robot system. The base station is configured to clean a cleaning system of a cleaning robot, and includes a base station body and a cleaning component. The base station body includes a cleaning groove, and the cleaning component is movably disposed on the base station body. The cleaning component includes a liquid outlet device, and cleaning liquid discharged by the liquid outlet device is configured to clean the cleaning system and enter the cleaning groove. After the cleaning component is positioned opposite to the cleaning system, the cleaning component moves, and the liquid outlet device moves along with the cleaning component. Then, the cleaning component can remove debris from the cleaning system. That is, the cleaning robot can realize automatic cleaning on the cleaning component.

First claim

What is claimed is:
