When you need serious cleaning power for demanding jobs, the Powerhorse Pressure Washer delivers 4,000 PSI at 4.0 GPM to blast through the toughest grime, grease, and buildup. This gas-powered cold water pressure washer combines professional-grade performance with user-friendly features that make it perfect for contractors, landscapers, facility managers, and property owners who need reliable cleaning power day after day.

At the heart of this pressure washer sits a robust Powerhorse 420cc OHV engine that provides consistent power while the dependable Annovi Reverberi direct drive triplex pump ensures optimal pressure and flow rates.
