Description
Zoom on the Generac 7901
The Generac 7901, a heavy duty pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- precise spot cleaning of hard, unpainted surfaces, reaching elevated areas, and effectively removing stubborn stains
- gentle cleaning for sensitive surfaces, and wide coverage cleaning with low pressure
- applying detergents and cleaning agents, and rinsing off surfaces
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
The Generac 7901's axial cam pump, powered by a 196cc engine, can provide a pressure of up to 3100 PSI (approximately 52 times more than a standard garden hose) and a flow of up to 2.4 GPM (values claimed by the manufacturer). Thus, the Generac 7901 achieves a cleaning power of 7440 Cleaning Units.
To initiate the Generac engine of this gas-powered pressure washer, a traditional pull-start mechanism is employed.
Gasoline is stored in a fuel tank with a maximum capacity of 0.8 gallon.
Design & Handling
The hand truck design of the Generac 7901 ensures effortless movement and transportation. The steel frame's robustness ensures the assembly's longevity, maintaining stability and protecting internal components, even in the harshest environments. The rubber-padded fixed handle adds to the 7901 convenience of transport, while offering a comfortable grip.
At 57 lbs, this unit strikes a balance between portability and stability, making it easy for most users to handle. That weight is mainly due to the inclusion of the 196cc Generac engine and a solid steel frame. Nevertheless, the 7901's two 10" never-flat wheels ensure it remains easy to maneuver.
Main Features
The Generac 7901's package includes a spray gun, a wand, a pressure hose, 4 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. As the Generac 7901 doesn’t include a soap dilution mechanism, the user must provide a correctly diluted detergent before proceeding to use it. When a soap nozzle is connected, the pressure washer takes the initiative to mix the detergent with the water flow automatically.
- Pressure hose: With a set of convenient hooks, the unit offers a practical solution for maintaining workspace order, allowing the included 25 ft ⌀1/4" high-pressure hose (3100 PSI rating) to be neatly stored when idle.
- Spray gun and wand: A side hook allows for an easy storage of the included PowerDial spray gun and its wand.
- Nozzles: Refer to the table below for details on the 4 included nozzles and their recommended surface applications.
0° | 25° | 40° | Soap | |
|---|---|---|---|---|
| Concrete, brick, masonry | ||||
| Siding, gutters, house | ||||

Other Features
- 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.
- Onboard storage: The Generac 7901's handy storage area lets you store nozzles and accessories, and thus, you’ll be always prepared and have everything necessary for the job at hand.
- 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: On top of an owner's manual (opens in a new tab) and the usual documentation to get you swiftly started, the Generac 7901 also comes with pressure hose, oil, funnel, wand and spray gun.
