Description
Zoom on the NorthStar 1571221
In a nutshell, the NorthStar 1571221 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:
- intense cleaning of tough, paintless surfaces
- cleaning of painted or delicate surfaces
- applying detergent and cleaning solutions
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
Using a 177cc engine, its triplex pump delivers a pressure of up to 3100 PSI (roughly 52 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 7750 Cleaning Units.
The KOHLER CH255 engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.
Gasoline is stored in a steel fuel tank with a maximum capacity of 0.78 gallon.
Design & Handling
The wheelbarrow design of the NorthStar 1571221 grants mobility and stability to the unit. The robust and sturdy steel tubing frame offers longevity to the assembly. The handle adds to the 1571221 convenience of transport.
The device weighs 95 lbs and thus, is far from lightweight. Transporting and manually lifting it may therefore pose a challenge. The main contributors to its weight are its 177cc KOHLER CH255 engine, the triplex pump and steel tubing frame. However, the unit is manipulated smoothly thanks to its two 10" never-flat wheels, which play a key role in its maneuverability.
Main Features
Along with the NorthStar 1571221 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 the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The NorthStar 1571221 includes an automatic soap dilution mechanism, which will dilute the detergent using a 15:1 ratio. When a soap nozzle is connected, the detergent will be added automatically to the water.
- 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.
15° | 25° | 40° | Soap | |

Concrete, brick, masonry | Suitable | Suitable | Suitable | Suitable |
Siding, gutters, house | Use with caution | Use with caution | Suitable | Suitable |

- Emissions: The NorthStar 1571221 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 1571221's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the NorthStar 1571221 compare to similarly priced pressure washers.
- The NorthStar 1571221 and its 3100 PSI, ranks amongst gas-powered pressure washers with a comparably low pressure output, considering the units that cost between $600 and $700. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the DeWalt DXPW3625, which reaches up to 3600 PSI.
- Considering the above-mentioned price range, this washer's maximum water flow of 2.5 GPM (gallons per minute) is higher than the average. If being able to rinse away debris as efficiently as possible is your priority, one of the products with the highest GPM in this price range is the Generac 6924, with 2.6 GPM.
