The DAPPER SUPPLY 18 in. 4350 PSI Pressure Washer Surface Cleaner is engineered for professional and homeowner-grade concrete, driveway, patio, deck, and exterior cleaning. Built with heavy-duty construction for long-lasting durability and corrosion resistance, this pressure washer surface cleaner attachment delivers professional results in less time than a wand-only setup. The 18 in. round cleaning disc covers large areas quickly for efficient surface prep on concrete, paver, sealed wood, brick, stamped concrete, garage floors, patios, driveways, and sidewalks. Dual high-pressure rotating nozzles spin at 250 RPM to deliver thorough, streak-free cleaning across the entire 18 in. cleaning footprint - eliminating wand stripes and uneven results common with single-nozzle work. The user-friendly design features four 360-degree caster wheels and ergonomic dual handles, gliding smoothly over flat concrete and 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. Lightweight 19 lb. design is easy to set up and reposition between cleaning zones. The splash-free skirt minimizes overspray and contains dirt, debris, and runoff for a cleaner, safer workspace. Backed by a 1-year manufacturer warranty.
