Abstract:
1. A robot cleaner system comprising: a robot cleaner comprising a robot body and a dust discharge hole to discharge dust stored in the robot body; and a docking station comprising a dust suction hole to suck the dust discharged out of the robot body, a dust suction path to guide the dust sucked through the dust suction hole, and a dust collector to collect the dust sucked through the dust suction hole, wherein the robot cleaner comprises a first docking portion to be inserted into the dust suction hole when the robot cleaner is docked with the docking station, and wherein the first docking portion is a protrusion, which protrudes out of the robot body to be inserted into the dust suction hole upon a docking operation, the protrusion communicates the dust discharge hole with the dust suction path, wherein the robot cleaner comprises an opening/closing device to mechanically open the dust discharge hole based only on mechanical contact with the docking station while the robot cleaner is docked with the docking station, the opening/closing device operating independently of a power state of the robot cleaner system.
