Abstract
An air/liquid separator is disclosed that is formed by a recovery tank having a hollow, preferably transparent, removable lid on a recovery tank of a wet pickup suction cleaner. The lid has a wall therein dividing the lid into an inlet/separating chamber and an exit chamber. Liquid and dirt entrained working air enters the inlet chamber and flows horizontally across the inlet chamber over a discharge opening passing through the lid bottom plate, such that the stream of dirty liquid and air is redirected downward through the discharge openings into the recovery tank by a pair of ribs in the inlet chamber. The exit chamber fluidly communicates with the interior of the recovery tank through an exit opening passing through the lid bottom plate. A vacuum is preferably drawn upon the exit chamber by an electric fan for providing the required working air flow through the combined air/liquid separator.
