1. A surface cleaning apparatus having a bottom and comprising:
- (a) a fluid flow path extending from a portable cleaning unit dirty fluid inlet to a clean air outlet of the surface cleaning apparatus;
(b) a wheeled based having a front end;
(c) a portable cleaning unit removably mounted on the wheeled base and comprising at least one cyclonic separation stage having an associated material collection chamber which is sealed when the portable cleaning unit is removed from the wheeled base, the portable cleaning unit dirty fluid inlet and a suction motor positioned in the fluid flow path, wherein the suction motor is positioned laterally horizontally spaced from the at least one cyclonic separation stage so as to be beside the at least one cyclonic separation stage when the portable cleaning unit is positioned upright on the wheeled base such that the at least one cyclone is not positioned on top of the suction motor;
(d) the surface cleaning apparatus having a cleaning mount located at the front end and proximal to the bottom; and
,(e) a surface cleaning attachment mountable to the cleaning mount and connectable in fluid flow communication with the portable cleaning unit dirty fluid inlet.
