Abstract

A brush assembly for a vacuum cleaner includes a brush cover; a brush base connected to the brush cover, a rotary drum disposed between the brush cover and the brush base, and an edge brush integrated bumper. The edge brush integrated bumper is mounted around a joint surface between the brush cover and the brush base. The edge brush integrated bumper includes a pair of edge brush portions integrally formed with the bumper. Each edge brush portion corresponds to a side of the brush cover and brushes off dust that is not accessible to the rotary drum. The brush assembly further includes assembling position guide means and fixing means for securing bumper to the brush cover. Since the bumper and edge brushes are integrally formed in an injection molding process, the number of separate parts to the brush assembly is reduced. Also, since the bumper and edge brushes can be assembled simultaneously, productivity is increased as assembly time is decreased.
