Disclosed is a cleaner which has an improved structure to improve the cooling efficiency of a motor. The cleaner comprises a suction unit which generates a suction force for inhaling air into a main body. The suction unit comprises: an impeller which is rotated around a shaft; a return channel in which a discharge path where air passing through the impeller flows is prepared; a motor which is arranged to provide power for rotating the impeller; and at least one support unit which is arranged to support the motor in the axial direction (X direction) of the impeller, wherein at least one support unit has cooling fins to extend at least a part of the discharge path in the axial direction (X direction) of the impeller. |
