Overview
This is a commercial cold-water pressure washer built around a Honda GX390 engine driving a 66DX CAT triplex pump, rated at 4000 PSI and 4.0 GPM. It's a direct-drive, gas-powered unit sized for daily professional cleaning — flatwork, fleet, equipment, and heavy grime that a homeowner machine can't keep up with. The aircraft-grade aluminum frame uses dual handles with no welds to fail and carries a lifetime frame warranty. An adjustable pressure unloader and thermo-sensor protect the pump in bypass, and it rolls on flat-free HD tires. It ships ready to run with a gun/wand, 50' hose, chemical injector, and a full nozzle set. Not for sale in California.
