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, paint-free surfaces and out-of-reach areas
- cleaning of painted or delicate surfaces
- application of detergent and cleaning solutions
Its power characteristics and design, its main features and all its additional features are presented ahead.
Power
The Generac 7122
Using a 196 cc engine, its brass axial cam pump delivers a pressure of up to 3200 PSI (roughly 53 times more than a standard garden hose) and a flow of up to 2.7 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 8640 Cleaning Units.
This gas-powered pressure washer’s Generac engine is started by a traditional pull-start mechanism.
Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.8 gallon.
Design & Handling
The Generac 7122 offers superb mobility, with a hand truck design and approximate dimensions of D24.2 x W18.9 x H35.5 in. The robust and sturdy steel frame offers 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. Since the 7122 has a set of two 10" never-flat wheels, it is still easily maneuvered and manipulated.
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. 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. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
- 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: Both the PowerDial spray gun and its wand may be conveniently stored in a side hook.
- Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.
0° | 25° | 40° | Soap | Turbo | |

- 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.

- 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: Included with the Generac 7122 are also the owner's manual and some basic documentation to get you promptly started, along with several accessories, such as wand, spray gun, funnel, Power Broom attachment, oil, pressure hose 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.
