A cleaning device including a suction motor; a suction head including a suction port; a rotatable brush inside the suction head; a brush motor; a pressure sensor; a memory storing coefficient tables including coefficients of a hyperplane equation for determining a type of surface to be cleaned; and a controller. The controller is configured to, in a first state with the suction head separated from the surface, select a reference coefficient table corresponding to a first suction pressure and a first load of the brush motor, in a second state with the suction head in contact with the surface, identify a type of the surface based on a second suction pressure, a second load of the brush motor, and the reference coefficient table, and adjust an output of the suction motor and/or the brush motor based on the identified type of the surface to be cleaned.

Cleaning device and control method thereof

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.
