• and
• a collector configured to:
• communicate with the lever device, and
• generate a suction force to suction dust collected in the dust collector,
• wherein the station comprises a cleaner seating portion on which the robot cleaner is seated,
• wherein the lever device includes:
• a lever having one end configured to be pressed by the robot cleaner, and
• a connection member arranged at the other end opposite to one end of the lever, the connection member configured to be connectable to a dust outlet,
• wherein, when the robot cleaner is seated on the cleaner seating portion, the robot cleaner is positioned to press the lever, and
• wherein, when the lever is pressed by the robot cleaner, the lever is rotated and moves the connection member toward a direction in which the connection member is connected to the dust outlet.
