This Dirt Driver Sapphire hot pressure washer replaces the older Sovereign model. These steam cleaners are competitively priced whilst still maintaining high build quality. This pressure washer has a steel powder coated chassis with a Polypropylene fuel tank and plastic water tank to guard against corrosion. Dirt Driver uses Hawk pumps, Danfoss fuel jets and Lavor Boilers. This combination of reliable components with simple wiring makes for a reliable industrial hot pressure washer.
