Abstract
A cleaner includes a suction motor mounted in a cleaner main body, and generating a suction force; a filter for collecting dust or filth sucked by the suction force generated at the suction motor; a suction head connected with the filter by a suction tube, and sucking dust and filth on a floor; a brush installed in the suction head so as to ascend/descend in a vertical direction, and sweeping dust and foreign substances into the suction head; and a brush height control apparatus installed in the suction head, and making the brush ascend/descend in a vertical direction. The cleaner having a brush height control apparatus can prevent deterioration of a suction force and improving cleaning performance by constantly maintaining a gap between the suction head and the floor.
