1. A hand carriable surface cleaning apparatus having, a front end, a rear end, a top and a bottom and comprising:
- (a) a dirty fluid inlet provided at the front end;
(b) an air treatment member downstream of the dirty fluid inlet and comprising an air treatment chamber having a lower end, an upper end, an air inlet and an air outlet at the upper end of the air treatment chamber;
(c) a pre-motor filter positioned in a pre-motor filter housing having an openable upper cover, the pre-motor filter is positioned above the upper end of the air treatment member chamber and downstream of the air treatment member and the pre-motor filter overlies at least a portion of the upper end of the air treatment member chamber when the bottom is resting on a horizontal surface;
(d) a suction motor positioned within a motor housing, downstream of the pre-motor filter and rearward of the air treatment member;
(e) a handle having a handle upper end adjacent a rear end of the pre-motor filter housing, a handle lower end that is positioned further rearward than the handle upper end and a grip portion extending therebetween, the handle upper end overlying the suction motor when the bottom is resting on a horizontal surface, wherein a plane that is transverse to a direction air travels when exiting the air outlet and that extends through the pre-motor filter intersects a finger gap that is provided proximate the grip portion to receive the fingers of a user;
(f) an air flow path extending from the pre-motor filter housing to the suction motor; and
,(g) a clean air outlet downstream of the suction motor.
