Self contained carpet extraction cleaners whilst not ideal for all applications, are extremely productive in less confined spaces. In corridors, function rooms and other open areas these units can very effectively deep clean, in excess of 400sq metres per hour. This is due to the built in, motor driven 450mm wide scrubbing brush and the powerful vacuum recovery system. The large capacity 38 Litre solution tank means fewer stops for re-filling. The Prowler has an OPTIONAL hose and wand to clean upholstery, stairs and confined places.
