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

The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

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.

The Honda GX200 engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.

A steel fuel tank with a maximum capacity of 0.8 gallon is used to store gasoline.

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.

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 major reasons for its heavy weight are its 193 cc Honda GX200 engine, the triplex pump and steel frame. However, the unit’s two 10" never-flat wheels are crucial to its maneuvrability, since they provide a smooth method of manipulation on the job.

Main Features

The NorthStar 157123 in use

The NorthStar 157123

Along with the NorthStar 157123 itself, the package also includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. The automatic soap dilution mechanism of the NorthStar 157123 will dilute the detergent with 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 following table illustrates the 4 included nozzles, along with the surfaces which they are the most suitable for.

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 and its 3300 PSI, ranks amongst gas-powered pressure washers with a comparably low pressure output, considering the units that cost between $800 and $900. If the highest possible power of the water stream is your priority, one of the champions in this price range is the DeWalt DXPW4440 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 rinsing away debris most efficiently is your priority, one of the devices with the highest GPM in this price range is the Generac 6565, which can reach up to 4 GPM.
  • The 157123 ranks as below average in terms of Cleaning Units, compared to gas-powered devices in its price range, reaching only a value of 8250 CU (PSI x GPM). If you are after the highest overall cleaning power, the DeWalt DXPW4440 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.
