  • comprehensive cleaning of hard surfaces, vehicle washing, and readying surfaces for painting

  • applying detergent and cleaning solutions, and rinsing surfaces

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 157127 in use

The NorthStar 157127

Its triplex pump, which utilizes a powerful 389cc (11.7 hp) engine, may deliver a pressure of up to 4200 PSI (almost 70 times more than a standard garden hose) and a flow of up to 3.5 GPM. Corresponding to these values is a cleaning power of 14700 Cleaning Units.

To initiate the Honda GX390 engine of this gas-powered pressure washer, a traditional pull-start mechanism is employed.

The pressure washer's steel tank has a maximum capacity of 1.5 gallon for storing gasoline.

Design & Handling

The wheelbarrow design of the NorthStar 157127 offers enhanced mobility and stability, making it ideal for navigating uneven terrain and ensuring steady operation during heavy-duty cleaning tasks. Built to endure, the steel tubing frame ensures the assembly's longevity by providing stability and safeguarding internal components under all working conditions. The handle adds to the 157127 convenience of transport.

With its weight clocking in at 145 lbs, this unit's heftiness can't be ignored, presenting significant difficulties for users who need to lift and transport it, especially over uneven terrain. The main contributors to its weight are its 389cc Honda GX390 engine, the triplex pump and steel tubing frame. Nonetheless, the addition of two 10" never-flat wheels simplifies maneuvering the 157127, even across rough ground.

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: Even without a built-in soap tank, the device relies on a siphon hose to provide detergent. With its automatic soap dilution mechanism, the NorthStar 157127 simplifies the process of blending detergent to the prescribed ratio of 15:1. Attachment of a soap nozzle prompts the pressure washer to automatically introduce and blend the detergent with the water.
  • Pressure hose: The unit comes equipped with an included 50 ft ⌀3/8" high-pressure hose, which can be neatly stored on the unit when idle, thanks to a set of convenient hooks, ensuring easy access and organization.
  • Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
  • Nozzles: Below, you'll find a table outlining the 4 included nozzles and their recommended surfaces.

  • With 4200 PSI, the NorthStar 157127 ranks as one that can reach an above average pressure, amongst the gas-powered products that cost between $1200 and $1500. 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, the GPM (gallons per minute) of this washer, which can reach 3.5, can be considered in the average. When it comes to efficiently rinsing away debris, one standout option within this price range is the DeWalt DXPW4440, delivering an impressive 4 GPM.
  • With a rather impressive value of 14700 Cleaning Units (PSI X GPM), the 157127 has a higher cleaning efficiency compared to similarly priced devices. If the highest overall cleaning power is a priority, the DeWalt DXPW4440 and its 17600 Cleaning Units are notable for their higher potential cleaning efficiency compared to units in the same price range.
