CLEANING DEVICE AND CONTROL METHOD FOR SAME

WIPO Patent Application WO/2023/219297

A1

A cleaning device disclosed herein comprises: a main body; a suction motor; a suction head including a suction port; a brush provided inside the suction head; a brush motor; a pressure sensor; a memory that stores a coefficient table including coefficients of hyperplane equations for determining the type of surface to be cleaned; and a control unit. The control unit selects a reference coefficient table, corresponding to a first suction pressure of the suction port and a first load of the brush motor, in a first state in which the suction head is spaced apart from the surface to be cleaned, identifies the type of the surface to be cleaned on the basis of a second suction pressure of the suction port, a second load of the brush motor, and the reference coefficient table, in a second state in which the suction head is in contact with the cleaning surface, and adjust the output of the suction motor and/or the output of the brush motor on the basis of the identified type of the surface to be cleaned.
