Zoom on the NorthStar 157123

The NorthStar 157123, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:

  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and frail surfaces
  • application of detergent and cleaning solutions

Ahead are presented its power characteristics and design, its main features and any other additional features.

Power

The NorthStar 157123 in use

The NorthStar 157123

With a 193 cc (6.5 hp) engine, its triplex pump delivers a pressure of 3300 PSI (roughly 55 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer), resulting in the NorthStar 157123's cleaning power of 8250 Cleaning Units.

This gas-powered pressure washer’s Honda GX200 engine is started by a traditional pull-start mechanism.

The fuel is stored in a steel tank, which can hold up to 0.8 gallon of gasoline.

Design & Handling

The wheelbarrow design of the NorthStar 157123 grants mobility and stability to the unit. Its sturdy steel frame provides longevity to the assembly. The handle adds to the 157123 convenience of transport.

With a weight of 95 lbs, the model is not lightweight. Therefore, it may be challenging to manually carry it around and transport it. The main contributors to its weight are its 193 cc Honda GX200 engine, the triplex pump and steel frame. However, the device’s two 10" never-flat wheels play a key role in its maneuverability, as they allow it to be manipulated smoothly.

Main Features

The NorthStar 157123 in use

The NorthStar 157123

The NorthStar 157123 comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The NorthStar 157123 features an automatic soap dilution mechanism, that will dilute your detergent with a 15:1 ratio. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
  • Pressure hose: The 50 ft ⌀3/8" high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
  • Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
  • Nozzles: The table below shows you the 4 included nozzles, as well as the surfaces they're the most appropriate for.
