Description
Zoom on the Generac 7122
In a nutshell, the Generac 7122 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:
- spot cleaning of hard, unpainted surfaces or high reach areas
- cleaning of painted and fragile surfaces
- application of detergent and cleaning solutions
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
The Generac 7122
Its brass axial cam pump, which utilizes a 196 cc engine, may deliver a pressure of up to 3200 PSI (almost 53 times more than a standard garden hose) and a flow of up to 2.7 GPM. These values correspond to a cleaning power of 8640 Cleaning Units.
A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Generac engine.
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.
Weighing 62 lbs, the unit is easy to maneuver by most people. One of the largest contributors to its weight are its 196 cc Generac engine and its steel frame. Nethertheless, thanks to its two 10" never-flat wheels, the 7122 remains very easy to manipulate and maneuver.
Main Features
The Generac 7122 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: A safe detergent storage is facilitated by a 0.5 gal tank. However, since the Generac 7122 does not feature a soap dilution mechanism, you'll have to make sure your detergent is correctly diluted before use. When a soap nozzle is connected, the detergent will be added automatically to the water.
- Pressure hose: The 30 ft ⌀1/5" high-pressure hose (3400 PSI rating), 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 PowerDial spray gun and its wand may be conveniently stored in a side hook.
- Nozzles: The 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
0° | 25° | 40° | Soap | Turbo | |
|---|---|---|---|---|---|
| Concrete, brick, masonry | Use with caution | Suitable | Suitable | Suitable | Use with caution |

Other Features
Some of the included accessories
- PowerDial™ gun: The PowerDial™ ergonomic spray gun features 4 different power modes, which can be selected simply, according to your cleaning task – soap, wood, concrete or car.
- Soap Blaster: The Soap Blaster attachment achieves a 3x longer spraying distance than a standard nozzle tip, allows you to penetrate tough stains and improves your overall cleaning results.
- 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.
- Pressure control: Water pressure can be manually changed, using the adjustable throttle of the trigger gun.
- 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).
- Accessories: The Generac 7122 comes with an owner's manual and some basic documentation to get you quickly started. On top of that, you also get Power Broom attachment, pressure hose, wand, spray gun, funnel, oil and Soap Blaster nozzle.
- Emissions: The Generac 7122 is CARB-compliant, and you may buy or sell it any of the 50 states, including California.
