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, unpainted surfaces or high reach areas
- cleaning of painted and fragile surfaces
- applying detergent and cleaning solutions
Powered by a 196 cc engine, its brass axial cam pump can deliver a pressure of 3200 PSI (around 53 times more than a standard garden hose) and a flow of up to 2.7 GPM (values claimed by the manufacturer). Combined, these values mean that the Generac 7122 has a cleaning power of 8640 Cleaning Units.
The Generac engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.
Gasoline is stored in a fuel tank with a maximum capacity of 0.8 gallon.
Design & Handling
Thanks to its hand truck design and approximate dimensions of D24.2 x W18.9 x H35.5 in, the Generac 7122 offers great mobility. The robust steel frame guarantees longevity of 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. Its 196 cc Generac engine and steel frame account for a good chunk of that weight. However, the two 10" never-flat wheels allow the 7122 to be easily manipulated and maneuvered.
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: Detergent is stored in 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. When a soap nozzle is connected, the detergent will be added automatically to the water.
- Pressure hose: Using a set of convenient hooks, the included 30 ft ⌀1/5" high-pressure hose (3400 PSI rating) can be easily stored on the unit when it is not running.
- Spray gun and wand: The included PowerDial spray gun and its wand can be easily 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.
