Zoom on the NorthStar 157123

The NorthStar 157123 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • intense cleaning of tough, paintless surfaces
  • cleaning of painted or delicate surfaces
  • applying 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 193cc (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.

The Honda GX200 engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

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 and sturdy steel frame offers longevity to the assembly. The handle adds to the 157123 convenience of transport.

At 95 lbs, we can't really say that the unit is a lightweight, and manually lifting or transporting it could be a challenge. The major reasons for its heavy weight are its 193cc Honda GX200 engine, the triplex pump and steel frame. 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: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The automatic soap dilution mechanism of the NorthStar 157123 will dilute the detergent with a 15:1 ratio. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
  • Pressure hose: Using a set of convenient hooks, the included 50 ft ⌀3/8" high-pressure hose can be easily stored on the unit when it is not running.
  • Spray gun and wand: A side hook enables you to easily store 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.

The NorthStar 157123's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the NorthStar 157123 compare to similarly priced pressure washers.

  • The NorthStar 157123, a device which can produce up to 3300 PSI, is on the lower end of the pressure spectrum, among the gas-powered pressure washers in the $800-900 price range. If the highest possible power of the water stream is your priority, one of the champions in this price range is the Simpson PS60843 with 4400 PSI.
  • In the aforementioned price range, this washer, with 2.5 GPM (gallons per minute), is placed on the lower end of the GPM scale. If you’re after the highest rinsing efficiency, one of the units with the highest water flow in the current price range is the Simpson PS60843, that can deliver up to 4 GPM.
  • Amongst similarly priced gas-powered devices, the 8250 Cleaning Units (PSI X GPM) of the 157123 rank as low. If you are after the highest overall cleaning power, the Simpson PS60843 with its 17600 Cleaning Units is one of the products that can achieve the highest cleaning efficiency in this price range.

Price comparison

As you can see from this interactive chart, when compared to other gas-powered washers between 8000 and 8500 Cleaning Units, the NorthStar 157123 is on the expensive side of the price range.

While certainly not the cheapest of its cleaning power range, purchasing it could most likely also mean enjoying the reliability of a high-end product.
