Zoom on the NorthStar 157123

In a nutshell, the NorthStar 157123 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:

  • intense cleaning of tough, paintless surfaces
  • cleaning of painted or delicate surfaces
  • applying 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

Its triplex pump, which utilizes a 193cc (6.5 hp) engine, may deliver a pressure of up to 3300 PSI (almost 55 times more than a standard garden hose) and a flow of up to 2.5 GPM. These values correspond to a cleaning power of 8250 Cleaning Units.

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

Gasoline storage is facilitated by a steel fuel tank with a maximum capacity of 0.8 gallon.

Design & Handling

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

The device weighs 95 lbs and thus, is far from lightweight. Transporting and manually lifting it may therefore pose a challenge. Its 193cc Honda GX200 engine, the triplex pump and steel frame are mainly responsible for its heavy weight. However, the unit is manipulated smoothly thanks to its two 10" never-flat wheels, which play a key role in its maneuverability.

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: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The NorthStar 157123 features an automatic soap dilution mechanism, that will dilute your detergent with a 15:1 ratio. The detergent is automatically added to the water when a soap nozzle is connected.
  • Pressure hose: The included 50 ft ⌀3/8" high-pressure hose can be neatly stored on the unit when idle thanks to 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 4 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
