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, andwherein the cyclone assembly comprises a sidewall that extends generally parallel to the cyclone axis of rotation and the pre-motor filter has an upstream surface that extends generally parallel to the sidewall of the cyclone assembly, andwherein the pre-motor filter has a downstream surface that is opposed to the upstream surface, and air exits the downstream surface in a generally vertical direction when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner.
