Description

Zoom on the NorthStar 1571343

The NorthStar 1571343 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and fragile 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 a powerful fuel-injected 420cc engine, its triplex pump can deliver a pressure of 4000 PSI (around 67 times more than a standard garden hose) and a flow of up to 3.5 GPM (values claimed by the manufacturer). Combined, these values mean that the NorthStar 1571343 has a cleaning power of 14000 Cleaning Units.

The NorthStar e420 engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.

Design & Handling

The wheelbarrow design of the NorthStar 1571343 grants mobility and stability to the unit. The robust and sturdy steel tubing frame offers longevity to the assembly. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

This model weighs 249 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 420cc NorthStar e420 engine, the triplex pump and steel tubing frame. However, the device’s two 15" never-flat wheels play a key role in its maneuverability, as they allow it to be manipulated smoothly.

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: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. The detergent is diluted with a 15:1 ratio by the NorthStar 1571343's automatic soap dilution mechanism. The detergent will be added automatically to the water when a soap nozzle is attached.
  • Pressure hose: A neat storage for the included 50 ft ⌀3/8" high-pressure hose is facilitated by 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.

  • Accessories: Besides the usual owner's manual (opens in a new tab) and documentation to get you promptly started, the NorthStar 1571343 comes with pressure hose, spray gun, soap hose and wand.
  • Emissions: The NorthStar 1571343 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

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 with its 4000 PSI achieves a lower pressure value, compared to other gas-powered pressure washers in the $1800-2200 price range. If you're going after the highest possible power of the water stream, one of the best in this price range is the Stihl RB 800 that can reach up to 4200 PSI.
  • The achievable water flow of this washer, which reaches 3.5 GPM (gallons per minute) can be described as low, compared to other 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 Stihl RB 800, with a GPM of 4.
  • The 1571343's Cleaning Units, 14000 CU (PSI X GPM), fall into the lower end when compared to gas-powered devices of similar price. If you are after the highest overall cleaning power, the Stihl RB 800 with its 16800 Cleaning Units is one of the products that can achieve the highest cleaning efficiency in this 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.
