Description

Zoom on the NorthStar 157160

In summary, the NorthStar 157160 is a heavy duty pressure washer, that offers an all-around versatile cleaning experience, and also:

  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and frail surfaces
  • applying detergent and cleaning solutions

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

Using an impressive 389 cc engine, its triplex pump delivers a pressure of up to 3000 PSI (roughly 50 times more than a standard garden hose) and a flow of up to 5 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 15000 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 NorthStar 157160 is very mobile, due to its hand truck design and approximate dimensions of L40.3 x W26 x H23.8 in. The robust steel tubing frame guarantees longevity of the assembly. The handle adds to the 157160 convenience of transport.

At 140 lbs, we can't really say that the unit is a lightweight, and manually lifting or transporting it could be a challenge. The major reasons for its heavy weight are its 389 cc Honda GX390 engine, the triplex pump and steel tubing frame. However, the unit is manipulated smoothly thanks to its two 10" never-flat wheels, which play a key role in its maneuvrability.

Main Features

Along with the NorthStar 157160 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: Detergent is fed in through a siphon hose, since the device lacks a soap tank. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
  • Pressure hose: The 50 ft ⌀3/8" 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: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
  • Nozzles: The table below shows you the 4 included nozzles, as well as the surfaces they're the most appropriate for.

Other Features

  • Onboard storage: The NorthStar 157160's handy storage area lets you store nozzles and accessories, and thus, you’ll be always prepared and have everything necessary for the job at hand.
  • Safety: Safety of operation is enhanced by a thermal relief valve (which helps to prevent internal pump damage), a low oil protection and a trigger lock mechanism (which prevents accidental operation).
  • Accessories: The NorthStar 157160 comes with an owner's manual and some basic documentation to get you quickly started. On top of that, you also get wand, spray gun and pressure hose.
  • Emissions: The NorthStar 157160 is EPA-approved and CARB-compliant. And so, this pressure washer is available for sale and purchase in any of the 50 states, including California.

The NorthStar 157160's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the NorthStar 157160 compare to similarly priced pressure washers.

  • The NorthStar 157160 and its 3000 PSI, ranks amongst gas-powered pressure washers with a comparably low pressure output, considering the units that cost between $1300 and $1700. 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, the 5 GPM (gallons per minute) of this washer makes it one of the best performing units in terms of the delivered volume of water.
  • With 15000 Cleaning Units (PSI x GPM), the 157160 is on the low end when compared to other similarly priced gas-powered devices. 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

As you can see from this interactive chart, when compared to other gas-powered washers between 14700 and 15800 Cleaning Units, the NorthStar 157160 is on the average side of the price range.

Therefore, this pressure washer nicely fits in the expected budget for this kind of cleaning power.
