Zoom on the NorthStar 157134

The NorthStar 157134, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:

  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and frail 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 157134 in use

The NorthStar 157134

Its triplex pump, which utilizes a powerful 389 cc (11.7 hp) engine, may deliver a pressure of up to 4000 PSI (almost 67 times more than a standard garden hose) and a flow of up to 3.5 GPM. These values correspond to a cleaning power of 14000 Cleaning Units.

This gas-powered pressure washer’s Honda GX390 engine is started by a traditional pull-start mechanism.

Gasoline storage is facilitated by a steel fuel tank with a maximum capacity of 1.6 gallon.

Design & Handling

The wheelbarrow design of the NorthStar 157134 grants mobility and stability to the unit. The robust steel tubing frame guarantees longevity of the assembly. The handle adds to the 157134 convenience of transport.

This model weighs 249 lbs. For this reason, it cannot be called lightweight and thus, carrying and transporting it might be somewhat challenging. The main contributor to its weight are its 389 cc Honda GX390 engine, the triplex pump and steel tubing frame. However, the device’s two 15" never-flat wheels play a key role in its maneuvrability, as they allow it to be manipulated smoothly.

Main Features

The NorthStar 157134 in use

The NorthStar 157134

Along with the NorthStar 157134 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 NorthStar 157134 includes an automatic soap dilution mechanism, which will dilute the detergent using a 15:1 ratio. The detergent is automatically added to the water when a soap nozzle is connected.
  • Pressure hose: The included 50 ft 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 following table illustrates the 4 included nozzles, along with the surfaces which they are the most suitable for.

  • The NorthStar 157134, with a max water pressure of 4000 PSI, has one of the higher PSI values of the gas-powered products in the $1400-1700 price range. As for the device with the most powerful water stream, in this price range, one of the top products is the Lifan LFQ4515E-Elite with 4500 PSI.
  • In the aforementioned price range, this washer, with 3.5 GPM (gallons per minute), is placed on the lower end of the GPM scale. In case you are looking for a device which can most efficiently rinse away debris in the current price range, the NorthStar 157160 has the highest GPM of 5.
  • Amongst similarly priced gas-powered devices, the 14000 Cleaning Units (PSI x GPM) of the 157134 rank as low. If you are after the highest overall cleaning power, the Lifan LFQ4515E-Elite with its 18000 Cleaning Units is one of the products that can achieve the highest cleaning efficiency in this price range.
