The DAPPER SUPPLY 20 in. 4350 PSI Pressure Washer Surface Cleaner is engineered for high-output professional concrete, driveway, patio, and commercial exterior cleaning. Built with heavy-duty construction for long-lasting durability and corrosion resistance, this 20 in. pressure washer surface cleaner delivers professional-grade results in significantly less time than a standard wand-only pressure washer. The 20 in. round cleaning disc covers large areas quickly for efficient surface prep on concrete slabs, paver patios, sealed wood decks, brick, stamped concrete, garage floors, driveways, sidewalks, parking pads, and exterior walkways. Dual high-pressure rotating nozzles spin at 250 RPM to deliver thorough, streak-free cleaning across the entire 20 in. cleaning footprint - eliminating the wand stripes and uneven cleaning lines common with single-nozzle pressure washing. The user-friendly design features four 360-degree caster wheels and ergonomic dual handles, allowing the surface cleaner to glide smoothly over concrete and flat outdoor surfaces. Includes a 3/8 in. quick-connect inlet and 2 hose adapters to fit most gas and electric pressure washers rated for 4350 PSI compatible operation. 26 lb. balanced weight for stability and control. Splash-free skirt minimizes overspray and contains dirt, debris, and runoff. 1-year warranty.
