Abstract: A cleaning device and a method therefor are provided. The cleaning device includes a vacuum cleaner including a dust collecting container and a docking station to which the dust collecting container is coupled. The docking station includes a suction device configured to move air from the dust collecting container to inside of the docking station, a collector configured to collect a foreign substance that is moved together with the air by driving of the suction device, a suction flow path along which air moves inside the docking station, a flow adjusting device configured to open or close the suction flow path, and at least one processor configured to control the suction device to operate based on the dust collecting container being coupled to the docking station, and control the flow adjusting device to periodically open and close the suction flow path in a state in which the suction device operates.
