1. A surface cleaning apparatus comprising:
- a) a liquid delivery system comprising at least one spray nozzle that delivers at least one liquid;
b) a separation stage comprising a separator and a separated liquid container in communication with a separated element outlet of the separator; and
,c) a fluid flow path extending from a dirty fluid inlet to a clean air outlet, the fluid flow path including the separator and a suction motor,wherein, when the surface cleaning apparatus is in a vertical orientation, the separated liquid container has a first portion underlying the separator, a second portion laterally spaced from the first portion and positioned below the separator and a third portion positioned above the second portion, and the third portion has a volume that is at least 80% of a volume of the first portion,wherein the separation stage further comprises a solid collection chamber and the first portion underlies the solid collection chamber, the second portion is laterally spaced from the first portion and is positioned below the solid collection chamber and the third portion is positioned above the second portion, and the third portion has a volume that is at least 80% of a volume of the first portion.
