Its power characteristics and design, its main features and all its additional features are presented ahead.
Power
Using an impressive fuel-injected 301cc engine, its triplex pump delivers a pressure of up to 3600 PSI (roughly 60 times more than a standard garden hose) and a flow of up to 3 GPM (values claimed by the manufacturer). When these values are taken together, they yield a cleaning power of 10800 Cleaning Units.
The NorthStar e300 engine of this gas pressure washer is activated by pulling a starter cord, following a traditional approach.
Fuel for the pressure washer is housed in a steel tank capable of holding up to 1.4 gallon of gasoline.
Design & Handling
With its wheelbarrow-inspired design, the NorthStar 1571243 aims for excellent mobility and stability, enabling effortless maneuvering and dependable performance across diverse environments. Built to endure, the steel tubing frame ensures the assembly's longevity by providing stability and safeguarding internal components under all working conditions. The handle adds to the 1571243 convenience of transport.
With its weight clocking in at 118 lbs, this unit's heftiness can't be ignored, presenting significant difficulties for users who need to lift and transport it, especially over uneven terrain. The major reasons for its heavy weight are its 301cc NorthStar e300 engine, the triplex pump and steel tubing frame. Despite this, the presence of two 10" never-flat wheels reduces the complexity of moving the 1571243, even on rugged surfaces.
Main Features

- Soap injection: Though lacking a dedicated soap tank, the device ensures detergent supply via a siphon hose. The NorthStar 1571243 includes an automatic soap dilution mechanism, which will dilute the detergent using a 15:1 ratio. Upon connecting a soap nozzle, the pressure washer takes over the task of seamlessly combining the detergent with the water flow.
