Abstract
A robot cleaner system having an improved docking structure between a robot cleaner and a docking station, which is capable of an easy docking operation of the robot cleaner and preventing loss of a suction force generated in the docking station. The robot cleaner includes a docking portion to be inserted into a dust suction hole of the docking station upon a docking operation. The docking portion may be a protrusion, which protrudes out of a robot body to be inserted into a dust suction path defined in the docking station, the protrusion communicates a dust discharge hole of the robot cleaner with the dust suction path of the docking station. The robot cleaner system includes a coupling device to keep the robot cleaner and the docking station in their docked state. The coupling device is configured to have a variety of shapes.
