Overview

This is a commercial 4 GPM, 4000 PSI cold-water pressure washer Pro-Pack built on a Honda GX390 engine with a heavy-duty V-belt-drive AR Viper VV4G42 pump. Belt drive runs the pump at lower RPM for cooler operation and longer life, making it suited to contractors running long jobs. The package bundles the machine with the tools to work faster: a 16" Whisper Wash (Ultra Clean 16) flat surface cleaner, two 50' non-marking high-pressure hoses, a gun/wand assembly, a 3/8" remote ball valve to switch between gun and surface cleaner, a detachable chemical injector, and five spray nozzles. Built on an aircraft-grade aluminum frame with a lifetime frame warranty.

Frequently asked questions

The Pro-Pack includes the Honda GX390 belt-drive pressure washer plus a full set of tools: a 16" Whisper Wash (Ultra Clean 16) flat surface cleaner, two 50' non-marking high-pressure hoses, a gun/wand assembly, a 3/8" remote ball valve, a detachable chemical injector, and five spray nozzles.

Belt drive runs the pump at a lower RPM than the engine, so it operates cooler and typically lasts longer under heavy, continuous use. That makes this unit well suited to contractors who run long jobs day in and day out.

The 3/8" remote ball valve lets you switch between the gun/wand and the surface cleaner without walking back to the machine. It keeps you moving between tasks so you finish jobs faster.

This is a cold-water pressure washer rated at 4 GPM and 4000 PSI. It handles most exterior and flatwork cleaning; it does not heat water.
