1. A surface cleaning apparatus comprising:
(a) an air flow path from a dirty air inlet in a front end of the surface cleaning apparatus to a clean air outlet;
(b) a momentum separator positioned downstream of the dirty air inlet, the momentum separator comprising an outer liquid collection chamber and an inner solid collection chamber that is positioned within the outer liquid collection chamber, the inner solid collection chamber having a front side, a rear side positioned rearward of the front side and a forward-rearward axis intersecting the front side and the rear side wherein, when the surface cleaning apparatus is in a use position to clean a surface, a portion of the outer liquid collection chamber is positioned below the inner solid collection chamber; and,
(c) a suction motor positioned downstream from the momentum separator,
wherein the inner solid collection chamber is separated from the outer liquid collection chamber by an inner chamber wall, and at least a portion of the inner chamber wall is porous and connects the inner solid collection chamber in fluid communication with the outer liquid collection chamber, and
wherein the air flow path comprises an inlet conduit that extends from the dirty air inlet to the inner solid collection chamber, a portion of the inlet conduit has a conduit axis extending centrally through the portion of the inlet conduit and
wherein a downstream air flow path extends from the inner solid collection chamber to the suction motor and the porous portion of the inner chamber wall connects the inner solid collection chamber in fluid communication with the downstream air flow path, and
wherein, when the surface cleaning apparatus is positioned on a floor with the portion of the outer liquid collection chamber positioned below the inner solid collection chamber and the forward-rearward axis extending horizontally, the conduit axis is inclined with respect to the forward-rearward axis at a location forward of the inner solid collection chamber.
