First Claim
1. An upright surface cleaning apparatus comprising:
- (a) a surface cleaning head having a front end, a rear end, a central longitudinal axis extending between the front and rear ends, a lateral plane that is transverse to the central longitudinal axis, first and second laterally opposed sides, a dirty aft inlet and a surface cleaning head air outlet;
(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 support structure and an air treatment member assembly comprising an air treatment member having a volume in which entrained material is separated from air entering the air treatment member, wherein all of the support structure is positioned rearward of a front face of the volume of the air treatment member assembly when the cleaning unit is in the generally upright position; and
,(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 wherein a lower end of the longitudinally extending member is mounted to the support structure;
the hand grip portion is located generally centrally relative to first and second lateral sides of the cleaning unit; and
a portion of the volume of the air treatment member assembly extends rearward of the longitudinally extending member when the cleaning unit is in the generally upright positionwherein the support structure comprises first and second laterally spaced struts positioned at an elevation of and rearward of the volume of the air treatment member and a cross member provided on an upper end of the struts, andwherein the support structure comprises an up flow duct and the longitudinally extending member is mounted to an upper end of the up flow duct.
