Overview

This is a 4000 PSI, 4 GPM cold-water pressure washer Pro-Pack built on a Honda GX390 engine with a heavy-duty V-belt-drive Cat pump. Belt drive runs the pump at reduced RPM for longer life and extended-duty operation, and the aircraft-grade aluminum frame with dual handles has no welds to fail, backed by a lifetime frame warranty. The package pairs the machine with a 19" Whisper Wash (Ultra Clean 19) flat surface cleaner, two 50' non-marking high-pressure hoses, a remote shut-off ball valve, a chemical injector, and a full nozzle set. It's built for contractors running flatwork and wash-down jobs who want everything to start working from day one.

Frequently asked questions

You get the 4 GPM / 4000 PSI cold-water Honda GX390 washer with Cat pump, a 19" Whisper Wash (Ultra Clean 19) surface cleaner, two 50' non-marking high-pressure hoses, a 5000 PSI gun/wand assembly, a detachable chemical injector, a 3/8" remote ball valve, and a full set of color-coded quick-connect spray nozzles.

The V-belt drive runs the Cat pump at reduced RPM, which lowers heat and wear for longer pump life and extended run times. That makes it better suited to contractors running the machine hard through long, back-to-back jobs.

The 3/8" ball valve lets you shut off flow and switch between the gun/wand and the surface cleaner remotely, without walking back to the machine. It saves time when you're alternating between flatwork and detail spraying.

Yes. The 19" Whisper Wash (Ultra Clean 19) is rated to 8 max GPM and 4200 max PSI, so it comfortably handles this washer's 4 GPM at 4000 PSI, with a maintenance-free rotary hub.
