Abstract
A vacuum cleaner is provided which can remove substances from a surface by a rotary force of a brush and a vacuum pressure operated on a suction head on which the brush is rotatably installed. The vacuum cleaner improves a user's convenience by preventing thin and long substances, such as hair or the fur of a pet dog, from being wound around the brush. The vacuum cleaner may include a suction head installed at a front end of a suction path, that sucks substances by a vacuum pressure generated by a suction motor and having a suction hole for sucking the substances, a brush installed in the suction hole and rotated to contact a surface, and a hair tunnel formed on the suction head so as not to interfere with the brush, that preferentially sucks thin and long substances from the surface.
