This high performance NorthStar Pressure Washer is an outstanding investment for protecting and maintaining equipment and property at home, job sites, factories, businesses and more.

Powerful Honda Engine

Never worry about your NorthStar Pressure Washer being ready for the task at hand. The commercial-grade Honda GX390 engine provides the ultimate reliability, plus easy-start convenience, improved power, greater fuel efficiency, longer run time and quieter operation.

Superior Quality and Durability

Proven Reliability

Equipped with a Comet triplex pump, this NorthStar Pressure Washer delivers field-proven dependability. The pump's direct drive design requires fewer moving parts, minimizing maintenance and maximizing value.

Greater Resistance, Longer Life

Small details make a big difference. The Comet pump used in this high-performance NorthStar Pressure Washer is designed with high-end ceramic plungers to provide maximum resistance to corrosion and abrasion, helping to extend pump life.

Rugged, Easy to Push, Low in Vibration

All of it adds up to a cart worthy of this high-performance NorthStar Pressure Washer. The premium push-down style cart with large 15in. pneumatic tires is easy to maneuver from job to job, saving time and effort. A rugged 1 3/8in. steel full roll cage provides maximum protection, an essential feature for withstanding the hard knocks of job sites. We took it a step further, engineering a unique vibration isolation system to help protect the pump and engine from excessive wear.
