Safety Features

Edge: Greenworks 1600 PSI Electric Pressure Washer

The physical construction differs between the two models. The Greenworks 1600 PSI Electric Pressure Washer is a compact unit with a closed design. The Greenworks 1800 PSI Open Frame Pressure Washer features an open frame design, which is taller at 31.7 inches high.
