Abstract
A wet/dry surface cleaning apparatus with an air flow path from a dirty air inlet to a clean air outlet with a motor and fan assembly positioned in the air flow path. The apparatus includes a first stage air treatment member comprising an air inlet and an air outlet, and a second stage air treatment member downstream from the first stage air treatment member. A partially treated air flow path extends between the first stage air treatment member and the second stage air treatment member. A valve is associated with the partially treated air flow path and operable to close the partially treated air flow path based on a water level in the first stage air treatment member.
