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 or high reach areas
  • cleaning of painted and frail surfaces
  • application of detergent and cleaning solutions

Ahead are presented its power characteristics and design, its main features and any other additional features.

Power

Powered by a 196 cc engine, its aluminum axial cam pump can deliver a pressure of 3100 PSI (around 52 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer). Combined, these values mean that the Generac 8894 has a cleaning power of 7750 Cleaning Units.

The Generac engine of this gas-powered pressure washer provides convenience and reliability, as it offers a dual starting mechanism: you may freely choose between the more modern electric start, or the old-school pull-start mechanism. The electric start requires a lithium-ion battery, which is included.

Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.8 gallon.

Design & Handling

The Generac 8894 offers superb mobility, with a hand truck design and approximate dimensions of D24.4 x W19 x H35.5 in. Its sturdy steel frame provides longevity to the assembly. The handle adds to the 8894 convenience of transport.

With a weight of 58.1 lbs, the unit can be easily maneuvered by most users. Its 196 cc Generac engine and steel frame all add up to a substantial part of that weight. The 8894 can still be easily manipulated and maneuvered, thanks to its two 10" never-flat wheels.

Main Features

The Generac 8894'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: Detergent is stored in a 0.6 gal tank. 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 25 ft ⌀1/4" high-pressure hose (3100 PSI rating) can be easily stored on the unit when it is not running.
  • Spray gun and wand: Both the PowerDial spray gun and its wand may be conveniently stored in a side hook.
  • Nozzles: The 4 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.
