1. A surface cleaning apparatus, comprising:
- a body having a forward compartment and rear compartment;
an elongate rotatable brush having bristles and extending across the forward compartment, the elongate rotatable brush further comprising a gear wheel at least one end of the brush;
an auxiliary brush extending from the forward compartment, the auxiliary brush having a body comprising a gear wheel that meshes with the elongate rotatable brush gear wheel for rotatably driving the auxiliary brush by the elongate rotatable brush; and
a belt connecting an electric motor and the rotatable brush;
wherein a front part of the forward compartment is movable to expose bristles on the elongate rotatable brush at the front part of the forward compartment.

19. A surface cleaning apparatus comprising:
-
a body having a forward compartment with an opening in a lower surface thereof, and a rear compartment; an elongate rotatable brush extending across the forward compartment, the elongate rotatable brush having bristles adapted to extend through the opening in the forward compartment as the brush is rotated, with the elongate rotatable brush further comprising a gear wheel at an end of the brush; an intermediate compartment defined by a wall between the forward compartment and the intermediate compartment, with a wall between the intermediate compartment and the rear compartment, and side walls; a belt connecting an electric motor to the rotatable brush; and an auxiliary brush extending from the forward compartment, the auxiliary brush having a body comprising a gear wheel that meshes with the elongate rotatable brush gear wheel for rotatably driving the auxiliary brush by the elongate rotatable brush, wherein a lower front region of the body is chamfered to increase the extent to which the bristles protrude from the body in the region of the chamfer such that, when the apparatus is inclined relative to a surface to be cleaned, contact between the bristles and the surface to be cleaned is increased. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
