Overview

This is a heavy-duty commercial belt-drive cold water pressure washer delivering 8.0 GPM at 3500 PSI, powered by an electric-start Honda GX690 engine paired with a low-RPM General Pump. That high-flow/high-pressure combination is built for contractors who need to move a lot of water — fleet washing, flatwork, and long production days. The 4-groove cog 3VX V-belt drive lets the pump spin slower than the engine for balanced power transfer and longer pump life, and a thermo-sensor protects against overheating in bypass. It's set up for tank feed with a 1" barbed inlet and external UL pump bypass hose, rides on an aircraft-grade aluminum frame with a lifetime warranty, and ships factory assembled and tested in the USA, ready to run. Battery not included.

Frequently asked questions

No — all 8 GPM units are set up for tank feed, drawing water through the 1" barbed inlet from a supply tank rather than a direct garden-hose hookup. The external UL pump bypass hose is part of that tank-feed configuration, so plan on running it with a buffer tank.

It includes a heavy-duty gun and wand assembly with quick connects, a 50' high-pressure hose with QC couplers, a Maxi-Flo 20% chem injector, four color-coded stainless QC spray nozzles, and one brass QC chemical nozzle. The unit arrives completely factory assembled and tested in the USA, ready to operate.

No, the standard unit is not for sale in California — its remote six-gallon poly fuel tank is not CARB evaporative compliant. A California-compliant upgrade is available as an option if you need to run it in-state.

Belt drive lets the General Pump run at lower RPM than the engine, which means less wear and a longer service life with minimal downtime. On this unit, the 4-groove cog 3VX V-belt system delivers balanced power transfer, with a single-bolt interlocking belt cover and easy-access belt tension adjustment for maintenance.
