Zoom on the NorthStar 157134

In summary, the NorthStar 157134 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

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 157134 in use

The NorthStar 157134

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.

A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Honda GX390 engine.

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 strong steel tubing frame assures assembly longevity. The handle adds to the 157134 convenience of transport.

The device weighs 249 lbs and thus, is far from lightweight. Transporting and manually lifting it may therefore pose a challenge. A key role in its final weight is played by 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 157134 in use

The NorthStar 157134

The NorthStar 157134 comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed 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 157134 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 50 ft high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
  • Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
  • Nozzles: The table below shows you the 4 included nozzles, as well as the surfaces they're the most appropriate for.

The NorthStar 157134's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the NorthStar 157134 compare to similarly priced pressure washers.

Note: Even though we couldn’t list its price on this page, our research indicates that some retailers sell this unit around $1700.

  • 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 $1550-1800 price range. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Lifan LFQ4515E-Elite, which reaches up to 4500 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 NorthStar 157130, with a GPM of 5.
  • The 157134 has 14000 Cleaning Units (PSI X GPM), which can be considered low in comparison to other gas-powered devices of this price. If you consider the highest overall cleaning power as a really important factor, the Lifan LFQ4515E-Elite and its 18000 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.

Price comparison
