Abstract:

The present invention relates to a charging station of a robot cleaner, the charging station comprising: a charging station body supplying electric power to a robot cleaner having a lower side, to which a mop in contact with floor surface is coupled, and a power module accommodated therein; a docking plate arranged at a side of the charging station body, and having an inclined surface in at least a part thereof and an upper portion on which the robot cleaner is docked; and a reaction force grounding groove which is recessed downward in the docking plate and formed to at least partially overlap a first rotary plate or a second rotary plate in the vertical direction when the robot cleaner is docked. Thus, a region where a reaction force that may interfere with the traveling of the robot cleaner is spaced apart from the docking plate such that the robot cleaner can easily climb the docking plate, and at the same time, moisture remaining in the mop is collected and dried.
