Abstract
A low profile upright surface cleaning apparatus comprises an air flow duct which has a length in a lateral direction that is transverse to the central longitudinal axis (front to back) of the surface cleaning head that is greater than a depth of the air flow duct in a direction of the central longitudinal axis.
Claims20
An upright surface cleaning apparatus comprising:
- (a) a surface cleaning head having a front end, a rear end, rear wheels having a diameter, a central longitudinal axis extending between the front and rear ends, first and second laterally opposed sides, a dirty air inlet and a surface cleaning head air outlet;
- and,
- (b) an upright section moveably mounted to the surface cleaning head between a generally upright position and a rearwardly inclined in use position, the upright section comprising an air treatment member assembly comprising a cyclone, a suction motor and an air flow duct defining a tangential inlet to the cyclone, wherein the upright section has a motor receiving portion housing the suction motor and a lateral portion laterally spaced from the motor receiving portion and the air flow duct is positioned laterally from the motor receiving portion,
- wherein the air flow duct at a location of the tangential inlet has a cross-section in a direction transverse to a direction of flow through the air flow duct, the cross-section has a length in a lateral direction that is transverse to the central longitudinal axis that is greater than a depth of the cross section of the air flow duct in a direction of the central longitudinal axis, and
- wherein the air flow duct has a flow direction that is generally lateral.
