Built with a robust frame and industrial-grade components, this pressure washer is designed to handle demanding cleaning tasks such as stripping grease from concrete, removing graffiti, cleaning fleet vehicles, and preparing surfaces for painting or coating. The NG Series lineup typically features powerful gas or electric motors paired with high-pressure triplex pumps, delivering the kind of sustained PSI and GPM output that contractors, industrial facilities, and cleaning service providers rely on to get tough jobs done efficiently.

What buyers report after months of use

Handles daily commercial jobs with ease2024-03-14

We run this unit five days a week on driveway and fleet cleaning contracts. The Honda engine starts every time and the pump hasn't missed a beat after eight months.

Powerful but heavy2024-01-22

Cleaning power is excellent for stripping paint and grease off concrete. Just wish it were lighter to load into the truck without help.

Denise R.
Worth the investment for pros2023-11-09

Bought this after burning out two consumer-grade washers. This is a completely different class of machine—built like a tank and cleans twice as fast.

Reliable workhorse2023-09-30

Great pressure and flow for commercial kitchen exterior cleaning. Maintenance schedule is a bit demanding but it pays off in uptime.
