Loading... Please wait...NorthStar® Hot Water/Steam pressure washer sprays hot water and steam up to 250°F @ 4 GPM and 3000 PSI. Coil assembly is fully encased in a custom-molded ceramic fiber refractory combustion chamber with low thermal conductivity and resistance to thermal shock. Rear hose-entry spray gun with split lance keeps the hose out of the way for easy handling. Includes a long-lasting, non-marking steel-braided rubber hose.
NorthStar hot water pressure washers are engineered to effectively sanitize surfaces, help to significantly reduce the prevalence of germs without disinfectant and maximize the effectiveness of disinfectant by providing the ultimate surface preparation.
Equipped with a high-quality Cat 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.
Small details make a big difference. The Cat 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.
All of it adds up to a cart worthy of the NorthStar high-performance Pressure Washer. The premium cart with large 14in. pneumatic tires is easy to maneuver from job to job, saving time and effort. A rugged 1 1/4in. 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.


The NorthStar pressure washer goes beyond power and performance with a long list of convenience features. Adjustable pressure means you're ready for virtually every job, big or small. Pump oil checks are quick and convenient using the handy sight glass. We've even made recoil pulling smoother and easier with Easy Start. A full complement of accessories is included.
