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 hard, unpainted surfaces
  • cleaning of painted and fragile surfaces
  • use of 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

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.

Gasoline is stored in 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 robust and sturdy steel frame offers longevity to the assembly. 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. The main contributor to its weight are its 193 cc Honda GX200 engine, the triplex pump and steel frame. However, the unit is mobile thanks to its two 10" never-flat wheels, which add to its movability and allow it to be manipulated smoothly 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: 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: 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 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, which can achieve a PSI of up to 3300, falls behind the other gas-powered pressure washers in the $825 to $900 price range. If you're going after the highest possible power of the water stream, one of the best in this price range is the DeWalt DXPW4440 that can reach up to 4400 PSI.
  • In comparison to other devices in the above-mentioned price range, this washer and its 2.5 GPM (gallons per minute), has one of the lower GPM values. In case you are looking for a device which can most efficiently rinse away debris in the current price range, the Generac 6565 has the highest GPM of 4.
  • Amongst similarly priced gas-powered devices, the 8250 Cleaning Units (PSI x GPM) of the 157123 rank as low. If the highest overall cleaning power is your top priority, the DeWalt DXPW4440, which can reach up to 17600 Cleaning Units, is one of the most efficient of the devices in the current 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.
