Simpson PowerShot Honda 4200 PSI Gas 4 GPM Pressure Washer 60456

The Simpson PowerShot PS4240 (Model 60456) Gas Pressure Washer is a commercial-grade cleaning powerhouse engineered to meet the rigorous demands of professional contractors and heavy-duty industrial applications. Delivering an impressive 4200 PSI at a flow rate of 4.0 GPM, this cold-water pressure washer provides the extreme cutting power and consistent reliability required for deep deck cleaning, wood restoration, meticulous paint preparation, graffiti removal, and extensive facility or fleet maintenance.

At the heart of this machine is a premium Honda GX390 commercial series overhead valve (OHV) engine. Renowned for its easy-pull recoil starting, smooth operation, and high power output, the engine features an integrated Oil Alert system that automatically shuts down the motor if oil levels drop too low, safeguarding your investment during long working hours. The engine is paired via a direct-drive system to an industrial AAA triplex plunger pump. This high-performance pump utilizes ceramic pistons and a forged brass head for an extended service life, and it features PowerBoost Technology to maximize water pressure directly at the spray nozzle tip.

The entire assembly is built upon a heavy-duty, welded steel construction frame and engine plate protected by a powder-coated finish to resist corrosion and structural wear in rugged field environments. Transporting the 136-pound unit across demanding job sites, mud, or unpaved terrain is made effortless by a solid steel axle and 13-inch premium pneumatic tires. For operational convenience, the frame features integrated on-board storage to keep the included professional spray gun, 31-inch wand, high-pressure hose, and quick-connect nozzles neatly organized and easily accessible.

The PowerShot comes fully equipped with premium plumbing and spray accessories designed for heavy daily use. It includes a 50-foot Monster high-pressure hose featuring a dual-braid design of polyester over a tough inner liner, wrapped in a non-marring, kink- and abrasion-resistant polyurethane outer jacket. Quick-connect fittings on the hose, professional spray gun, and the 31-inch steel wand allow for rapid, secure attachments. To accommodate a diverse range of surfaces and cleaning intensities, the package includes five stainless steel quick-connect nozzle tips varying from a pinpoint stream to wide fan patterns, along with a specialized downstream siphon tube system for applying chemical detergents.
