Description
Zoom on the NorthStar 1571103
The NorthStar 1571103 is a heavy duty pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- overall cleaning of hard surfaces, washing vehicles, and prepping surfaces for painting
- mild cleaning for delicate surfaces, and low-pressure cleaning for broader areas
- applying detergents and cleaning agents, and rinsing off surfaces
Its power characteristics and design, its main features and all its additional features are presented ahead.
Power
Powered by a 30-amp motor, 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 2.5 GPM (values claimed by the manufacturer). With these values combined, the NorthStar 1571103 boasts a cleaning power of 7500 Cleaning Units.
The 1571103 starts up effortlessly with a quick press of an ON/OFF switch, ensuring ease of use. The unit is ready-to-use with peace of mind, thanks to the included 36 ft GFCI cord.
It should be noted that the unit requires a dedicated 240V electrical circuit to operate. The included cord has a NEMA 6-30P plug, which should be plugged into a 6-30R receptacle.
Design & Handling
The NorthStar 1571103's wheelbarrow-style design enhances both mobility and stability, enabling seamless navigation and consistent performance, even on rugged terrain. The robust steel frame guarantees longevity of the assembly, providing stability and protection for internal components, even under demanding working conditions. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
Weighing in at 130 lbs, it's safe to say this unit isn't lightweight, which might pose difficulties for users when it comes to lifting and transporting, particularly over uneven surfaces. Its motor, the triplex pump and steel frame add up to a large chunk of the device's weight. Nevertheless, with its two 10" never-flat wheels, users can manage the 1571103 with less difficulty, even over uneven terrain.
Main Features
Along with the NorthStar 1571103 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: Despite the absence of a soap tank, detergent supply is facilitated through the use of a siphon hose. The pressure washer automatically dispenses and mixes the detergent with the water when a soap nozzle is attached.
- Pressure hose: For easy organization, the included 25 ft high-pressure hose can be stored on the unit using a set of convenient hooks when it's not in use, ensuring a clutter-free workspace.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
- Nozzles: In the table below, you can see the 4 included nozzles alongside their respective recommended surface uses.

| Concrete, brick, masonry | ||||

Other Features
- Total Stop System (TSS): This function automatically stops the pressure washer when the trigger is released, prolonging the pump's lifespan.
- Onboard storage: Stay prepared for any job with NorthStar 1571103'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) and a trigger lock mechanism (which prevents accidental operation).
- Accessories: On top of an owner's manual (opens in a new tab) and the usual documentation to get you swiftly started, the NorthStar 1571103 also comes with wand, pressure hose, soap hose, oil, power cord and spray gun.
