Abstract: An operating method of a station device for discharging dust from a cordless vacuum cleaner includes detecting occurrence of an event requesting discharging dust from a dustbin included in the cordless vacuum cleaner to the station device, and performing a dust discharge operation for discharging dust in the dustbin to a collector of the station device based on detecting of the occurrence of the event. The performing a dust discharge operation includes transmitting, to the cordless vacuum cleaner via short-range wireless communication, a control signal for operating a first suction motor of the cordless vacuum cleaner, and operating a second suction motor of the station device in cooperation with the first suction motor.

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.
