Description
Zoom on the Generac 7122
The Generac 7122 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- spot cleaning of hard, paintless surfaces and reaching far-away areas
- cleaning of painted or delicate surfaces
- use 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.
This gas-powered pressure washer’s Generac engine is started by a traditional pull-start mechanism.
Gasoline is stored in a fuel tank with a maximum capacity of 0.8 gallon.
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. The strong steel frame assures assembly longevity. The rubber-padded fixed handle adds to the 7122 convenience of transport, while offering a comfortable grip.
The device can be maneuvered with ease by most, since it only weighs 62 lbs. Its 196 cc Generac engine and steel frame all add up to a substantial part of that weight. But, as the 7122 does have a set of two 10" never-flat wheels, it can be easily maneuvered and manipulated.
Main Features
The Generac 7122's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: A safe detergent storage is facilitated by a 0.5 gal tank. It must be noted that the Generac 7122 doesn’t come with a soap dilution mechanism. Therefore, you must always make sure that your detergent is correctly diluted. 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: The included PowerDial spray gun and its wand can be easily stored in a side hook.
- Nozzles: The following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.
0° | 25° | 40° | Soap | Turbo | |

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: The Generac 7122 allows you to be always fully prepared, as it features a handy storage area, where nozzles and accessories can be stored.
- Pressure control: Water pressure can be manually changed, using the adjustable throttle of the trigger gun.
- Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation) and a thermal relief valve (which helps to prevent internal pump damage).
- 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, funnel, wand, pressure hose, spray gun, oil and Soap Blaster nozzle.
- Emissions: The Generac 7122 is CARB-compliant. Thus, it can be bought and sold in any of the 50 states, including California.
