Abstract

A surface cleaning apparatus wherein a body comprises a scalloped wall that defines a suction motor chamber that houses a suction motor.

Claims

1. A surface cleaning apparatus comprising:

(a) a body comprising a wall defining a suction motor chamber that houses a suction motor, the suction motor comprising a fan rotatable about a suction motor axis and a motor, the fan is mounted to a first end of the motor and is located in the suction motor chamber and the motor has a second end opposed to the first end, the wall comprises a sidewall extending generally parallel to the suction motor axis and an end wall spaced from and facing the second end of the motor wherein the end wall has a central longitudinal axis that extends in a direction of the suction motor axis, a raised section and a rounded section, the raised section is positioned centrally in the end wall, the raised section comprises a continuous central surface without any air flow openings therein that extends inwardly along the central longitudinal axis towards the second end of the motor and the rounded section is formed as a curved section extending from the sidewall to the raised section which is rotated about the central longitudinal axis so as to define a rounded wall that from the interior of the suction motor chamber provides a continuous concave section extending around the raised section;

(b) an air treatment member; and

,

(c) an air flow path extending from a dirty air inlet to a clean air outlet and including the suction motor and the air treatment member.

2. The surface cleaning apparatus of claim 1 wherein the sidewall of the suction motor chamber has an air outlet.

3. The surface cleaning apparatus of claim 1 wherein the suction motor chamber has an air outlet in an upper portion thereof.

4. The surface cleaning apparatus of claim 3 wherein the suction motor is supported on a plurality of ribs and the air outlet comprises openings between the ribs.
