1. A hand vacuum cleaner comprising:
- a) a main body comprising a fluid flow motor;
b) a first cyclonic cleaning stage having first and second spaced apart ends and comprising a cyclone chamber, the cyclone chamber having first and second spaced apart ends, a dirty fluid inlet and a clean fluid outlet, wherein the first end of the cyclone chamber is positioned above the second end of the cyclone chamber when the hand vacuum cleaner is positioned on a horizontal surface;
c) a handle comprising a portion that extends upwardly when the hand vacuum cleaner is positioned on a horizontal surface; and
,d) a wand mounted to the dirty fluid inlet, the wand having a distal inlet that is mounted on a surface cleaning headwherein the dirty fluid inlet defines a passage extending along a passage axis, wherein the passage axis intersects the handle.
