Abstract
A portable extractor apparatus is shown which includes a wheel mounted base having a solution tank for dispensing and recovering cleaning solution. A cleaning head communicates with the solution tank and contacts the surface to the cleaned for dispensing and recovering cleaning solution. A fluid pump circulates cleaning solution in a path between the solution tank and the cleaning head. A vacuum motor provides a vacuum source for the cleaning head for suctioning the surface being cleaned. The solution tank has mounted thereon both an initial multi-component filter assembly which initially filters incoming solution being circulated to the solution tank and a distinct final filter component which removes smaller particles from the solution being re-circulated from the tank. The solution tank bottom wall has a profile which improves the efficiency of the final filter component.
