1. 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.
