Overview

This is a commercial cold-water pressure washer that delivers 4000 PSI at 4 GPM, driven by a Honda GX390 engine and a heavy-duty CAT belt-drive pump. The belt drive turns the pump slower than the engine, cutting heat and wear for long daily runtimes, which is why contractors pick it over cheaper direct-drive units. It rides on an aircraft-grade aluminum frame with dual handles and no welds to fail, backed by a lifetime frame warranty. Built for pros running the machine hard on fleet washing, concrete and flatwork, and equipment cleaning. It ships ready to run with a 50-foot hose, gun and lance, and a downstream chemical injector, all on quick connects.
