Zoom on the Generac 8894
In a nutshell, the Generac 8894 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, reaching high areas, and removing stubborn stains
- gentle cleaning of delicate surfaces, and low pressure cleaning of larger areas
- applying detergents or chemicals, and rinsing surfaces afterward
Its power characteristics and design, its main features and all its additional features are presented ahead.
Power
With a 196cc engine powering it, the aluminum axial cam pump of this unit is capable of achieving a pressure of 3100 PSI (approximately 52 times greater than that of a standard garden hose) and a flow rate of up to 2.5 GPM (values claimed by the manufacturer). Corresponding to these values is a cleaning power of 7750 Cleaning Units.
Equipped with a dual starting mechanism, the Generac engine of this gas-powered pressure washer offers both convenience and reliability: you are presented with the choice between the modern convenience of the electric start or the traditional reliability of the pull-start mechanism. A lithium-ion battery, which is included in the package, is required for the electric start.
Gasoline is stored in a fuel tank with a maximum capacity of 0.8 gallon.
Design & Handling
Enhanced mobility is a key feature of the Generac 8894, thanks to its hand truck design. The sturdy steel frame ensures the longevity of the assembly, offering stability and protection for internal components, even during rigorous use. The handle adds to the 8894 convenience of transport.
With a weight of 58.1 lbs, the unit is comfortably maneuverable for most users, allowing for efficient handling during cleaning tasks. Its 196cc Generac engine and steel frame account for a good chunk of that weight. However, with its two 10" never-flat wheels, the 8894 is easy to maneuver.
Main Features
Along with the Generac 8894 itself, the package also includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: The pressure washer features a 0.6 gal tank for detergent storage. Attachment of a soap nozzle prompts the pressure washer to automatically introduce and blend the detergent with the water.
- Pressure hose: For easy organization, the included 25 ft ⌀1/4" high-pressure hose (3100 PSI rating) can be stored on the unit using a set of convenient hooks when it's not in use, ensuring a clutter-free workspace.
- Spray gun and wand: A side hook enables you to easily store the included PowerDial spray gun and its wand.
- Nozzles: The table below shows you the 4 included nozzles and the surfaces they're the most appropriate for.
0° | 25° | 40° | Soap | |
|---|---|---|---|---|
| Concrete, brick, masonry | ||||
| Siding, gutters, house | ||||

- Onboard storage: The Generac 8894'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.
- 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).
