Description
Zoom on the NorthStar 157122
In summary, the NorthStar 157122 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and fragile 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 157122
Its triplex pump, which utilizes a 163 cc (4.8 hp) engine, may deliver a pressure of up to 3100 PSI (almost 52 times more than a standard garden hose) and a flow of up to 2.5 GPM. These values correspond to a cleaning power of 7750 Cleaning Units.
A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Honda GX160 engine.
Gasoline storage is facilitated by a steel fuel tank with a maximum capacity of 0.83 gallon.
Design & Handling
The wheelbarrow design of the NorthStar 157122 grants mobility and stability to the unit. The robust steel tubing frame guarantees longevity of the assembly. The handle adds to the 157122 convenience of transport.
At 95 lbs, we can't really say that the unit is a lightweight, and manually lifting or transporting it could be a challenge. Its 163 cc Honda GX160 engine, the triplex pump and steel tubing frame add up to a large chunk of the device's weight. 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 157122
Along with the NorthStar 157122 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: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The NorthStar 157122 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 included 50 ft high-pressure hose can be neatly stored on the unit when idle thanks to 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 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
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 |
| Lawn equipment, boat, RV | Use with caution | Use with caution | Use with caution | Suitable |

The NorthStar 157122's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the NorthStar 157122 compare to similarly priced pressure washers.
- The NorthStar 157122 with its 3100 PSI achieves a lower pressure value, compared to other gas-powered pressure washers in the $800-900 price range. If the highest possible power of the water stream is your priority, one of the champions in this price range is the Simpson PS60843 with 4400 PSI.
- In the aforementioned price range, this washer, with 2.5 GPM (gallons per minute), is placed on the lower end of the GPM scale. In case you are looking for a device which can most efficiently rinse away debris in the current price range, the Simpson PS60843 has the highest GPM of 4.
- With 7750 Cleaning Units (PSI X GPM), the 157122 is on the low end when compared to other similarly priced gas-powered devices. If you consider the highest overall cleaning power as a really important factor, the Simpson PS60843 and its 17600 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.

As you can see from this interactive chart, when compared to other gas-powered washers between 7500 and 8000 Cleaning Units, the NorthStar 157122 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.
