A durable 55 PSI pump delivers extracting solution into the carpet. The steel heater chassis is mounted in its own roto-molded tank and frame. Roto-molded polyethylene body withstands the toughest working environments and resists dents, chips and cracks. The 2-stage Ametek 804 watt / 100 CFM vacuum motor efficiently recovers spent solution and soils which allows for faster carpet drying. Double ball-bearing urethane wheels and slide-out carrying handle makes transport easy.
