1. A surface cleaning apparatus comprising:
(a) a first liquid separation stage comprising a cyclone having a cyclone axis of rotation, a cyclone first end, an axially spaced apart second end, a cyclone air inlet, a cyclone air outlet and an axially extending sidewall wherein a portion of the sidewall comprises a porous section and, when the surface cleaning apparatus is in use to clean a floor, the cyclone axis of rotation extends generally horizontally; and,
(b) a first liquid collection region that is positioned at a lower elevation than the porous section wherein the porous section connects the cyclone in flow communication with the first liquid collection region,
wherein, in operation to clean a wet surface, water separated in the cyclone travels through the porous section to the first liquid collection region and air exits the cyclone through the cyclone air outlet.
