Abstract
A surface cleaning apparatus includes a rotatably mounted brush associated with a dirty air inlet. A plurality of bristles extend outwardly from a radial outer surface of the rotatably mounted brush. A leading hair blocking member is provided adjacent a forward rotational side of the bristles, and a trailing hair blocking member is provided adjacent a rearward rotational side of the bristles.
Claims20
A surface cleaning apparatus for cleaning a floor comprising:
- a) an air flow path extending from a dirty air inlet to a clean air outlet with an air treatment member and a suction motor provided in the air flow path;
- b) a rotatably mounted brush associated with the dirty air inlet, the rotatably mounted brush having an axis of rotation, a length in the axial direction, a radial outer surface, and first and second axially spaced apart sides;
- c) a plurality of bristles extending outwardly from the radial outer surface, the bristles having a bristle length from the radial outer surface to an outer end of the bristles;
- d) a leading hair blocking member provided adjacent a forward rotational side of the bristles, the leading hair blocking member having a length from the radial outer surface to an outer end of the leading hair blocking member;
- and,
- e) a trailing hair blocking member provided adjacent a rearward rotational side of the bristles, the trailing hair blocking member having a length from the radial outer surface to an outer end of the trailing hair blocking member,
- wherein the trailing hair blocking member interacts with the floor during rotation of the brush, and
- wherein the trailing hair blocking member is made of an elastomeric material.

- wherein the trailing hair blocking member is less flexible than the leading hair blocking member, and
- wherein, when the bristles and the trailing hair blocking member each contact the floor, the outer ends of the leading and trailing hair blocking members define a plane that is adjacent the outer ends of the bristles.
