Abstract: 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.

Abstract: A robot includes a traveling part, a communication interface including a UWB module, a distance sensor, a memory, and a processor configured to receive, a first UWB signal from the object through a UWB module, identify, based on the received first UWB signal, whether it is located in a same space as with the object, based on identifying that the robot is located in the same space as with the object, control the robot travel to the object based on the received first UWB signal, and control, based on identifying that the robot is located in a space different from the object, control the traveling part to move the robot to the same space as with the object by using coordinate information of the robot and the object received from the beacon located in the same space as with the robot and a sensing value obtained from the distance sensor.
