发明名称 Cleaner having brush
摘要 A cleaner having a brush includes a suction motor mounted in a 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 pipe, and having an inlet through which dust and filth on a floor are sucked; and a brush rotatably mounted at an inside of the suction head. The inlet is partitioned off into a first section and a second section by a belt cover for protecting a belt winding around the brush, and a flow passage unit is formed at the brush so that air can flow between the first and second sections. Accordingly, air can flow smoothly at a portion, which is blocked by the belt cover, and thus cleaning performance can be improved.
