Description

Zoom on the NorthStar 1571343

The NorthStar 1571343, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:

  • general cleaning of hard surfaces , washing vehicles, and preparing surfaces for painting
  • gentle cleaning for sensitive surfaces, and wide coverage cleaning with low pressure
  • applying detergents or chemicals, and rinsing surfaces afterward

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

With an impressive fuel-injected 420cc engine, its triplex pump delivers a pressure of 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), resulting in the NorthStar 1571343's cleaning power of 14000 Cleaning Units.

For this gas-powered pressure washer, the NorthStar e420 engine is started using a time-tested pull-start mechanism.

Design & Handling

Characterized by its wheelbarrow layout, the NorthStar 1571343 provides improved mobility and stability, facilitating easy movement and steadfast operation for effective cleaning results. Built to endure, the steel tubing frame ensures the assembly's longevity by providing stability and safeguarding internal components under all working conditions. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

With its weight clocking in at 249 lbs, this unit's heftiness can't be ignored, presenting significant difficulties for users who need to lift and transport it, especially over uneven terrain. A key role in its final weight is played by its 420cc NorthStar e420 engine, the triplex pump and steel tubing frame. However, the incorporation of two 15" never-flat wheels makes navigating the 1571343 less cumbersome, even on uneven terrain.

Main Features

Along with the NorthStar 1571343 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: While not equipped with a soap tank, the device maintains detergent supply through a siphon hose. The detergent is diluted with a 15:1 ratio by the NorthStar 1571343's automatic soap dilution mechanism. Connection of a soap nozzle triggers the pressure washer to automatically incorporate the detergent into the water stream.
  • Pressure hose: The unit comes equipped with an included 50 ft ⌀3/8" high-pressure hose, which can be neatly stored on the unit when idle, thanks to a set of convenient hooks, ensuring easy access and organization.
  • Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
  • Nozzles: Find details on the 4 included nozzles and their recommended surface applications in the table below.

  • Onboard storage: The NorthStar 1571343 allows you to be always fully prepared, as it features a handy storage area, where nozzles and accessories can be stored.
  • 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 1571343 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, soap hose, pressure hose and spray gun.

The NorthStar 1571343's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the NorthStar 1571343 compare to similarly priced pressure washers.

  • The NorthStar 1571343, 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 $1800-2200 price range. For those prioritizing maximum water stream power, consider the Stihl RB 800, boasting 4200 PSI, as a standout performer in this price range.
  • Compared to other products in the price range noted above, this washer, boasting 3.5 GPM, sits on the lower side of potential water flow. In case you are looking for a device which can most efficiently rinse away debris in the current price range, the Stihl RB 800 has the highest GPM of 4.
  • The 1571343 has 14000 Cleaning Units (PSI X GPM), which can be considered low in comparison to other gas-powered devices of this price. If the highest overall cleaning power is a priority, the Stihl RB 800 and its 16800 Cleaning Units are notable for their higher potential cleaning efficiency compared to units in the same price range.

Price comparison

As you can see from these interactive charts, when compared to other gas-powered washers between 13800 and 14700 Cleaning Units, the NorthStar 1571343 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.
