Great for trucks and equipment

We use this washer around our small service yard for trucks, trailers, and muddy equipment. The water volume makes a big difference when rinsing dirt and road grime. It is not a lightweight household washer, but that is exactly why we chose it.

Built like a commercial machine

This pressure washer feels heavy-duty from the first setup. The engine starts well, the triplex pump looks solid, and the wheels handle rough ground better than expected. I use it for equipment cleanup and concrete pads, and it has saved a lot of time compared with my older unit.

Serious cleaning power for concrete

I bought this for cleaning a long concrete driveway and a shop area with oil marks. The pressure is much stronger than my smaller residential washer, and the 4.2 GPM flow helps rinse large areas faster. The frame feels solid, and the hose length is useful for moving around without constantly repositioning the unit.
