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:

  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and frail surfaces
  • use of detergent and cleaning solutions

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

The NorthStar 157123 in use

The NorthStar 157123

The NorthStar 157123's triplex pump, powered by a 193 cc (6.5 hp) engine, can provide a pressure of up to 3300 PSI (approximately 55 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer). The NorthStar 157123 thus has a cleaning power of 8250 Cleaning Units.

A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Honda GX200 engine.

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. The robust steel frame guarantees longevity of 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. Its 193 cc Honda GX200 engine, the triplex pump and steel frame add up to a large chunk of the device's weight. However, its two 10" never-flat wheels play an important part in its maneuverability, as they allow for a smooth manipulation on the job.

Main Features

The NorthStar 157123 in use

The NorthStar 157123

The NorthStar 157123'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: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The detergent is diluted with a 15:1 ratio by the NorthStar 157123's automatic soap dilution mechanism. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
  • Pressure hose: A neat storage for the included 50 ft ⌀3/8" high-pressure hose is facilitated by a set of convenient hooks.
  • Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
  • Nozzles: The 4 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.
