The SIMPSON PowerShot professional gas pressure washer delivers 4000 PSI at 3.5 GPM for the cleaning power and water flow needed to take on demanding outdoor jobs. It is built for contractors, property owners and maintenance professionals who need dependable performance for frequent cleaning projects. Use it for jobs such as cleaning decks, restoring wood, preparing surfaces for paint, washing concrete, removing stubborn grime and maintaining outdoor equipment. The CRX 420 engine provides reliable gas-powered performance and includes low-oil shutdown to help protect the engine during operation. A AAA Triplex pump with PowerBoost technology supports consistent high-pressure water delivery for professional cleaning applications. The 50 ft. dual-braided Monster high-pressure hose with quick-connect fittings provides practical reach around work areas while helping the operator spend less time repositioning the pressure washer. A welded steel frame with a powder-coated finish helps provide durability and corrosion resistance for regular transport and jobsite use. The 13 in. premium pneumatic tires help move the unit across driveways, yards and other common outdoor surfaces. Five quick-connect nozzle tips including 0°, 15°, 25°, 40° and soap let the operator adjust the spray pattern for different cleaning tasks, while the 31 in. quick-connect spray lance supports convenient nozzle changes. Designed as part of the SIMPSON PowerShot Series, this 49-state cold-water pressure washer combines professional cleaning capability with the mobility and accessories needed for demanding property maintenance and cleaning work.
