The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.
Power
The NorthStar 157127
The NorthStar 157127's triplex pump, powered by a powerful 389cc (11.7 hp) engine, can provide a pressure of up to 4200 PSI (approximately 70 times more than a standard garden hose) and a flow of up to 3.5 GPM (values claimed by the manufacturer). Thus, the NorthStar 157127 achieves a cleaning power of 14700 Cleaning Units.
For this gas-powered pressure washer, the Honda GX390 engine is started using a time-tested pull-start mechanism.
Fuel for the pressure washer is housed in a steel tank capable of holding up to 1.5 gallon of gasoline.
Design & Handling
The wheelbarrow design of the NorthStar 157127 offers enhanced mobility and stability, making it ideal for navigating uneven terrain and ensuring steady operation during heavy-duty cleaning tasks. The steel tubing frame's robustness ensures the assembly's longevity, maintaining stability and protecting internal components, even in the harshest environments. The handle adds to the 157127 convenience of transport.
With its weight clocking in at 145 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. Its 389cc Honda GX390 engine, the triplex pump and steel tubing frame are mainly responsible for its heavy weight. However, the incorporation of two 10" never-flat wheels makes navigating the 157127 less cumbersome, even on uneven terrain.
Main Features
The NorthStar 157127
The NorthStar 157127's package includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. The NorthStar 157127 features an automatic soap dilution mechanism that dilutes detergent according to a predefined ratio of 15:1. When a soap nozzle is connected, the pressure washer takes the initiative to mix the detergent with the water flow automatically.
- Pressure hose: With a set of convenient hooks, the unit provides a convenient way to store the included 50 ft ⌀3/8" high-pressure hose when not in use, keeping it organized and readily accessible.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
- Nozzles: Below, you'll find a table outlining the 4 included nozzles and their recommended surfaces.

| Concrete, brick, masonry | ||||
| Siding, gutters, house | ||||
