HANDHELD SURFACE CLEANING APPARATUS
First Claim
1. A hand vacuum cleaner having a front end, a rear end, an upper end, a lower end and first and second laterally spaced apart sides and comprising:
- (a) an air flow path extending from a dirty air inlet to a clean air outlet;
(b) a cyclone assembly comprising a cyclone chamber positioned in the air flow path and having a cyclone air inlet, a cyclone air outlet and a cyclone axis of rotation, wherein the cyclone axis of rotation extends generally in a forward/rearward direction;
(c) a pre-motor filter positioned downstream of the cyclone air outlet; and
,(d) a suction motor positioned in the air flow path downstream of the pre-motor filter and upstream of the clean air outlet and having a suction motor axis of rotation,wherein the pre-motor filter is vertically spaced from the cyclone axis of rotation when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner, andwherein air travels generally rearwardly from the pre-motor filter to the suction motor.

Abstract
A hand vacuum cleaner has an air flow path extending from a dirty air inlet to a clean air outlet. A cyclone chamber positioned in the air flow path has a cyclone air inlet and a cyclone air outlet. A pre-motor filter is positioned downstream of the cyclone air outlet and a suction motor is positioned in the air flow path downstream of the pre-motor filter. The pre-motor filter is vertically spaced from the cyclone axis of rotation when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner, and air travels generally rearwardly from the pre-motor filter to the suction motor.
