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:

  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and fragile 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 157160's triplex pump, powered by an impressive 389 cc engine, can provide a pressure of up to 3000 PSI (approximately 50 times more than a standard garden hose) and a flow of up to 5 GPM (values claimed by the manufacturer). The NorthStar 157160 thus has a cleaning power of 15000 Cleaning Units.

The Honda GX390 engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.

A steel fuel tank with a maximum capacity of 1.6 gallon is used to store gasoline.

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.

This model weighs 140 lbs. For this reason, it cannot be called lightweight and thus, carrying and transporting it might be somewhat challenging. 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 10" never-flat wheels are crucial to its maneuverability, since they provide a smooth method of manipulation on the job.

Main Features

The NorthStar 157160 comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The detergent is automatically added to the water when a soap nozzle is connected.
  • 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: 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.

Other Features

  • Onboard storage: Stay prepared for any job with NorthStar 157160's handy storage area, which allows you to neatly store any nozzles and accessories which you may need for the 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: Included with the NorthStar 157160 are also the owner's manual (opens in a new tab) and some basic documentation to get you promptly started, along with several accessories, such as wand, pressure hose and spray gun.
  • 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.

Note: Even though we couldn’t list its price on this page, our research indicates that some retailers sell this unit around $1599.

  • 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 the highest possible power of the water stream is your priority, one of the champions in this price range is the Stihl RB 800 with 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.
  • As the 157160 has a total of 15000 Cleaning Units (PSI X GPM), it finds itself in the average cleaning efficiency range for similarly priced gas-powered units. 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.
