Description

Zoom on the NorthStar 157160

The NorthStar 157160, a heavy duty pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:

  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and frail surfaces
  • use of detergent and cleaning solutions

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

Power

Powered by an impressive 389 cc engine, its triplex pump can deliver a pressure of 3000 PSI (around 50 times more than a standard garden hose) and a flow of up to 5 GPM (values claimed by the manufacturer). Combined, these values mean that the NorthStar 157160 has a cleaning power of 15000 Cleaning Units.

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

Gasoline is stored in a steel fuel tank with a maximum capacity of 1.6 gallon.

Design & Handling

With its hand truck design and approximate dimensions of L40.3 x W26 x H23.8 in, the NorthStar 157160 provides great mobility. The strong steel tubing frame assures assembly longevity. The handle adds to the 157160 convenience of transport.

With a weight of 140 lbs, the model is not lightweight. Therefore, it may be challenging to manually carry it around and transport it. The major reasons for its heavy weight are its 389 cc Honda GX390 engine, the triplex pump and steel tubing frame. However, the device’s two 10" never-flat wheels play a key role in its maneuverability, as they allow it to be manipulated smoothly.

Main Features

The NorthStar 157160'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 though the device doesn't have a soap tank, detergent is supplied by a siphon hose. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • 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 enables you to easily store the included classic ergonomic spray gun and its wand.
  • Nozzles: The 4 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

Other Features

  • Onboard storage: With the NorthStar 157160's handy storage area, you’ll always have all the necessary nozzles and accessories at hand and thus, you’ll be fully prepared for any job.
  • Safety: Safety of operation is enhanced by a thermal relief valve (which helps to prevent internal pump damage), a trigger lock mechanism (which prevents accidental operation) and a low oil protection.
  • Accessories: On top of an owner's manual (opens in a new tab) and the usual documentation to get you swiftly started, the NorthStar 157160 also comes with wand, spray gun and pressure hose.
  • Emissions: The NorthStar 157160 is EPA-approved and CARB-compliant. Therefore, the sale and purchase of this pressure washer is permitted in all 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, a device which can produce up to 3000 PSI, is on the lower end of the pressure spectrum, among the gas-powered pressure washers in the $1350-1600 price range. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Stihl RB 800, which reaches up to 4200 PSI.
  • With a water flow of up to 5 GPM (gallons per minute), this washer belongs to the best of the above-mentioned price range, as it can deliver a high volume of water.
  • The 157160 ranks as below average in terms of Cleaning Units, compared to gas-powered devices in its price range, reaching only a value of 15000 CU (PSI x GPM). In case you are looking for the highest overall cleaning power, in this price range, one of the current champions is the Stihl RB 800 and its 16800 Cleaning Units.

Price comparison

As you can see from this interactive chart, when compared to other gas-powered washers between 14500 and 16000 Cleaning Units, the NorthStar 157160 is on the expensive side of the price range.

While certainly not the cheapest of its cleaning power range, purchasing it could most likely also mean enjoying the reliability of a high-end product.
