Description
Zoom on the NorthStar 157127
In a nutshell, the NorthStar 157127 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
- use of detergent and cleaning solutions
Its power characteristics and design, its main features and all its additional features are presented ahead.
Power
The NorthStar 157127
With an impressive 389cc (11.7 hp) engine, its triplex pump delivers a pressure of 4200 PSI (roughly 70 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 157127's cleaning power of 14700 Cleaning Units.
A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Honda GX390 engine.
A steel fuel tank with a maximum capacity of 1.5 gallon is used to store gasoline.
Design & Handling
The NorthStar 157127 offers superb mobility, with a hand truck design and approximate dimensions of L40.3 x W26 x H23.8 in. Its sturdy steel tubing frame provides longevity to the assembly. The handle adds to the 157127 convenience of transport.
The device weighs 145 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 389cc Honda GX390 engine, the triplex pump and steel tubing frame. However, the device’s two 10" never-flat wheels play a key role in its maneuverability, as they allow it to be manipulated smoothly.
Main Features
The NorthStar 157127
The NorthStar 157127's package includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The NorthStar 157127 has an automatic soap dilution mechanism, which dilutes the detergent using a 15:1 ratio. The detergent will be added automatically to the water when a soap nozzle is attached.
- Pressure hose: The included 50 ft ⌀3/8" high-pressure hose can be neatly stored on the unit when idle thanks to a set of convenient hooks.
- Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
- 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 |
| Fencing, deck, patio | Use with caution | Use with caution | Suitable | Suitable |

The NorthStar 157127's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the NorthStar 157127 compare to similarly priced pressure washers.
- The NorthStar 157127, with a max water pressure of 4200 PSI, has one of the higher PSI values of the gas-powered products in the $1200-1500 price range. If the highest possible power of the water stream is your priority, one of the champions in this price range is the Lifan LFQ4515E-Elite with 4500 PSI.
- When compared to devices in the above-mentioned price range, this washer and its 3.5 GPM (gallons per minute), is on the lower end of the achievable water flow. 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 DeWalt DXPW4440, with 4 GPM.
- As the 157127 has a total of 14700 Cleaning Units (PSI X GPM), it finds itself in the average cleaning efficiency range for similarly priced gas-powered units. If you are after the highest overall cleaning power, the Lifan LFQ4515E-Elite with its 18000 Cleaning Units is one of the products that can achieve the highest cleaning efficiency in this price range.
