Abstract: An air cleaner adapted to filter out various types of substances through a filter assembly, as well as automatically remove the filtered substances, and a method for controlling the operation of such an air cleaner, are provided. The air cleaner may include a rotation brush unit installed on an inner wall surface of a front panel, facing a front surface of a mesh-type filter body and adapted to rotate while maintaining contact with the front surface of the filter body. When a suction operation is terminated, the rotation brush unit may to remove dust accumulated on the surface of the mesh-type filter body.

Abstract: Disclosed is a new type of air cleaner adapted to primarily filter out various types of alien substances (e.g. dust) through a filter assembly, as well as automatically remove the alien substances that have been filtered out, and a method for controlling the operation of the air cleaner. The air cleaner includes a rotation brush unit installed on the inner wall surface of the front panel to face the front surface of the mesh-type filter body and adapted to rotate while maintaining contact with the front surface of the mesh-type filter body. When the air-drawing unit stops operation, the rotation brush unit is operated to remove dust accumulated on the surface of the mesh-type filter body of the filter assembly, which is installed near the air inlet.
