Surface cleaning apparatus

An upright surface cleaning apparatus comprising:

• (a) a surface cleaning head having a front end, a rear end, rear wheels, a central longitudinal axis extending between the front and rear ends in a forward rearward direction, first and second laterally opposed sides that are spaced apart in a lateral direction, a dirty air inlet and a surface cleaning head air outlet, wherein the lateral direction is perpendicular to the forward rearward direction;
• (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 having a cleaning unit, and a push handle, the cleaning unit comprising an air treatment member assembly comprising an air treatment member and a suction motor housing having a suction motor therein and the push handle comprising a longitudinally extending member having a longitudinally extending drive axis and a hand grip portion provided at an upper end of the longitudinally extending member wherein the drive axis extends through the air treatment member assembly and the suction motor housing, wherein the air treatment member assembly has first and second laterally spaced apart sides that are spaced apart in the lateral direction;
• and,
• (c) a rotatable mount rotatably mounting the upright section with respect to the surface cleaning head about an upright section axis wherein the rotatable mount is generally centrally positioned in the forward rearward direction beneath a volume defined by the air treatment member assembly when the upright section is in the generally upright position, and the rotatable mount is positioned in the lateral direction between the first and second laterally spaced apart sides of the air treatment member assembly,
• wherein an axis of rotation of the rear wheels is positioned beneath the volume defined by the air treatment member assembly when the upright section is in the generally upright position, and
• wherein the suction motor is positioned beneath the volume defined by the air treatment member assembly when the upright section is in the generally upright position.

• (a) a surface cleaning head having a front end, a rear end, rear wheels, a central longitudinal axis extending between the front and rear ends, first and second laterally opposed sides that are spaced apart in a lateral direction, a dirty air inlet and a surface cleaning head air outlet, wherein the lateral direction is perpendicular to the forward rearward direction;
• (b) a cleaning unit moveably mounted to the surface cleaning head between a generally upright position and a rearwardly inclined in use position, the cleaning unit comprising a front face having a forward most portion provided in a front plane that is transverse to a forward direction of travel of the surface cleaning head when the cleaning unit is in the generally upright position, a rear face having a rearward most portion provided in a rear plane that is transverse to the forward direction when the cleaning unit is in the generally upright position, an air treatment member assembly comprising an air treatment member, a dirt collection region exterior to the air treatment member and a suction motor therein, wherein the air treatment member assembly has first and second laterally spaced apart sides that are spaced apart in the lateral direction, wherein the suction motor is below the air treatment member assembly when the cleaning unit is in the generally upright position, wherein the cleaning unit defines an air treatment volume extending between the front plane and the rear plane, and the air treatment member and the dirt collection region are both positioned within the air treatment volume;
• (c) a push handle comprising a longitudinally extending member having a longitudinally extending drive axis and a hand grip portion provided at an upper end of the longitudinally extending member;
• and,
• (d) a rotatable mount rotatably mounting the cleaning unit with respect to the surface cleaning head about a cleaning unit axis;
• wherein an axis of rotation of the rear wheels and the rotatable mount are located beneath the air treatment volume when the cleaning unit is in the generally upright position, and the rotatable mount is positioned in the lateral direction between the first and second laterally spaced apart sides of the air treatment member assembly when the cleaning unit is in the generally upright position.
