Abstract: A cleaning device is provided. The cleaning device includes a vacuum cleaner which includes a dust collecting bin and a docking station to which the vacuum cleaner is coupled, wherein the docking station includes a charger configured to be electrically connected to a charging terminal of the vacuum cleaner in response to the vacuum cleaner being coupled to the docking station, a door driver configured to open or close a dust collecting bin door disposed at a lower portion of the dust collecting bin, a suction device configured to move air from the dust collecting bin into the docking station, a collector configured to collect foreign matter that moves together with the air due to driving the suction device, and a controller configured to control the door driver to open the dust collecting bin door in response to the charging terminal of the vacuum cleaner being electrically connected to the charger, configured to control the suction device to supply a suctioning air flow to the dust collecting bin and perform a discharge operation in response to the dust collecting bin door being opened, and configured to control the door driver to close the dust collecting bin door in response to an end of the discharge operation.

Abstract: An operating method of a cordless vacuum cleaner includes detecting connection of a brush device to a cleaner body, through a voltage value input to an input port of at least one processor through a signal line or a load detection sensor of the cleaner body, identifying a type of the brush device connected to the cleaner body, when the connection of the brush device to the cleaner body is detected, determining a frequency for pulse width modulation (PWM) control corresponding to the identified type of the brush device, and controlling an operation of the switch device used to supply power from a battery of the cleaner body to the brush device connected to the cleaner body.
