Zoom on the NorthStar 157127

In a nutshell, the NorthStar 157127 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
  • 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 157127 in use

The NorthStar 157127

With an impressive 389cc (11.7 hp) engine, its triplex pump delivers a pressure of 4200 PSI (roughly 70 times more than a standard garden hose) and a flow of up to 3.5 GPM (values claimed by the manufacturer), resulting in the NorthStar 157127's cleaning power of 14700 Cleaning Units.

A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Honda GX390 engine.

A steel fuel tank with a maximum capacity of 1.5 gallon is used to store gasoline.

Design & Handling

The NorthStar 157127 offers superb mobility, with a hand truck design and approximate dimensions of L40.3 x W26 x H23.8 in. Its sturdy steel tubing frame provides longevity to the assembly. The handle adds to the 157127 convenience of transport.

The device weighs 145 lbs and thus, is far from lightweight. Transporting and manually lifting it may therefore pose a challenge. The main contributors to its weight are its 389cc Honda GX390 engine, the triplex pump and steel tubing 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 157127 in use

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: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The NorthStar 157127 has an automatic soap dilution mechanism, which dilutes the detergent using a 15:1 ratio. The detergent will be added automatically to the water when a soap nozzle is attached.
  • 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: 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.
