Description
Zoom on the NorthStar 157124
In a nutshell, the NorthStar 157124 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 and frail surfaces
- use of detergent and cleaning solutions
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
The NorthStar 157124
The NorthStar 157124's triplex pump, powered by an impressive 270 cc (8.5 hp) engine, can provide a pressure of up to 3600 PSI (approximately 60 times more than a standard garden hose) and a flow of up to 3 GPM (values claimed by the manufacturer). The NorthStar 157124 thus has a cleaning power of 10800 Cleaning Units.
A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Honda GX270 engine.
The fuel is stored in a steel tank, which can hold up to 1.4 gallon of gasoline.
Design & Handling
The wheelbarrow design of the NorthStar 157124 grants mobility and stability to the unit. The strong steel tubing frame assures assembly longevity. The handle adds to the 157124 convenience of transport.
The unit's weight of 118 lbs renders its carrying and transportation challenging, as it is far from lightweight. The main contributors to its weight are its 270 cc Honda GX270 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
The NorthStar 157124
Along with the NorthStar 157124 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 157124 features an automatic soap dilution mechanism, that will dilute your detergent with a 15:1 ratio. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
- Pressure hose: A neat storage for the included 50 ft 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.
15° | 25° | 40° | Soap | |
|---|---|---|---|---|
| Concrete, brick, masonry | Suitable | Suitable | Suitable | Suitable |

The NorthStar 157124's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the NorthStar 157124 compare to similarly priced pressure washers.
- The NorthStar 157124 with its 3600 PSI achieves a lower pressure value, compared to other gas-powered pressure washers in the $1000-1400 price range. In case you are looking for a device with the highest possible power of its water stream, one of the top achievers in this price range is the Lifan LFQ4515E-CA with a PSI of 4500.
- The achievable water flow of this washer, which reaches 3 GPM (gallons per minute) can be described as low, compared to other devices in its price range. If rinsing away debris most efficiently is your priority, one of the devices with the highest GPM in this price range is the DeWalt DXPW4440, which can reach up to 4 GPM.
- The 157124's Cleaning Units, 10800 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 Lifan LFQ4515E-CA with its 18000 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 this interactive chart, when compared to other gas-powered washers between 9600 and 11900 Cleaning Units, the NorthStar 157124 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.
