Zoom on the Generac 7122
In summary, the Generac 7122 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- spot cleaning of hard, unpainted surfaces and high-reach cleaning
- cleaning of painted and fragile surfaces
- applying detergent and cleaning solutions
The Generac 7122's brass axial cam pump, powered by a 196 cc engine, can provide a pressure of up to 3200 PSI (approximately 53 times more than a standard garden hose) and a flow of up to 2.7 GPM (values claimed by the manufacturer). The Generac 7122 thus has a cleaning power of 8640 Cleaning Units.
This gas-powered pressure washer’s Generac engine is started by a traditional pull-start mechanism.
A fuel tank with a maximum capacity of 0.8 gallon is used to store gasoline.
Design & Handling
The Generac 7122 is very mobile, due to its hand truck design and approximate dimensions of D24.2 x W18.9 x H35.5 in. Its sturdy steel frame provides longevity to the assembly. The rubber-padded fixed handle adds to the 7122 convenience of transport, while offering a comfortable grip.
Most users can maneuver this model easily, as it weighs just 62 lbs. One of the largest contributors to its weight are its 196 cc Generac engine and its steel frame. However, the two 10" never-flat wheels allow the 7122 to be easily manipulated and maneuvered.
Along with the Generac 7122 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: Detergent storage is ensured by a 0.5 gal tank. The Generac 7122 is not equipped with a soap dilution mechanism, and thus, it is up to the user to ensure the detergent’s correct dilution ratio when using it. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
- Pressure hose: A neat storage for the included 30 ft ⌀1/5" high-pressure hose (3400 PSI rating) is facilitated by a set of convenient hooks.
- Spray gun and wand: A side hook allows for an easy storage of the included PowerDial spray gun and its wand.
- Nozzles: The 5 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

- Power Broom: Generac’s Power Broom features a 12” surface coverage with high pressure nozzles, which are up to 4x faster than standard nozzles. It performs excellently when cleanings deck, patios, driveways and sidewalks.
- Onboard storage: Stay prepared for any job with Generac 7122'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).

The Generac 7122's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the Generac 7122 compare to similarly priced pressure washers.
- The Generac 7122, which can achieve a PSI of up to 3200, falls behind the other gas-powered pressure washers in the $500 to $600 price range. If you're going after the highest possible power of the water stream, one of the best in this price range is the DeWalt DXPW3625 that can reach up to 3600 PSI.
- In the aforementioned price range, the 2.7 GPM (gallons per minute) of this washer makes it one of the better performing units in terms of the delivered volume of water. If maximum rinsing efficiency is your top priority, one of the devices with the highest water flow in the same price range is the Lifan LFQ3370, with a GPM of 3.
- With the 7122's 8640 Cleaning Units (PSI X GPM), its cleaning efficiency range may be considered average, compared to gas-powered units of similar price. If you consider the highest overall cleaning power as a really important factor, the Lifan LFQ3370 and its 9900 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 8500 and 9000 Cleaning Units, the Generac 7122 is on the average side of the price range.
Therefore, this pressure washer nicely fits in the expected budget for this kind of cleaning power.
