GX390 Honda 4 GPM 4200 PSI Belt Drive Commercial Pressure Washer VIPER Pump

Overview

This is a contractor-grade Honda GX390 belt-drive pressure washer rated at 4200 PSI and 4.0 GPM, bundled as a Pro Pack with the tools you need to start working. It runs a heavy-duty VIPER pump on a belt drive, which spins the pump slower than a direct-drive unit for cooler running and longer pump life on all-day jobs. The package pairs the machine with a 16″ Whisper Wash flat surface cleaner and a remote shut-off ball valve so you can switch between the gun and the surface cleaner without walking back to the machine. Built for flatwork, fleet washing, and other commercial cleaning where speed and uptime matter.
