Zoom on the NorthStar 157136

In summary, the NorthStar 157136 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:

  • intense cleaning of tough, paintless 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 157136 in use

The NorthStar 157136

Using a powerful 389 cc (11.7 hp) engine, its triplex pump delivers a pressure of up to 4000 PSI (roughly 67 times more than a standard garden hose) and a flow of up to 3.5 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 14000 Cleaning Units.

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

The fuel is stored in a steel tank, which can hold up to 1.6 gallon of gasoline.

Design & Handling

The wheelbarrow design of the NorthStar 157136 grants mobility and stability to the unit. Its sturdy steel tubing frame provides longevity to the assembly. The handle adds to the 157136 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 major reasons for its heavy weight are its 389 cc Honda GX390 engine, the triplex pump and steel tubing frame. However, the unit’s two 15" never-flat wheels are crucial to its maneuverability, since they provide a smooth method of manipulation on the job.

Main Features

The NorthStar 157136 in use

The NorthStar 157136

The NorthStar 157136 comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed 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 157136's automatic soap dilution mechanism. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • 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: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
  • Nozzles: The 4 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

  • The NorthStar 157136, a device which can produce up to 4000 PSI, is on the lower end of the pressure spectrum, among the gas-powered pressure washers in the $1900-2100 price range. As for the device with the most powerful water stream, in this price range, one of the top products is the DeWalt DXPW60606 with 4200 PSI.
  • This washer, with a GPM of 3.5 (gallons per minute) has a somewhat lower water flow value compared to devices in its price range. If maximum rinsing efficiency is your top priority, one of the devices with the highest water flow in the same price range is the DeWalt DXPW60606, with a GPM of 4.
  • The 157136 has 14000 Cleaning Units (PSI x GPM), which can be considered low in comparison to other gas-powered devices of this price. In case you are looking for the highest overall cleaning power, in this price range, one of the current champions is the DeWalt DXPW60606 and its 16800 Cleaning Units.
