Zoom on the Generac 8894

The Generac 8894 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • spot cleaning of hard, paint-free surfaces and out-of-reach areas
  • cleaning of painted and frail surfaces
  • use of detergent and cleaning solutions

The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

Power

Its aluminum axial cam pump, which utilizes a 196 cc engine, may deliver a pressure of up to 3100 PSI (almost 52 times more than a standard garden hose) and a flow of up to 2.5 GPM. These values correspond to a cleaning power of 7750 Cleaning Units.

With a dual start mechanism, the Generac engine of this gas-powered pressure washer provides convenience and reliability: you can either choose the practical electric start, or the traditional 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

Thanks to its hand truck design and approximate dimensions of D24.4 x W19 x H35.5 in, the Generac 8894 offers great mobility. The strong steel frame assures assembly longevity. The handle adds to the 8894 convenience of transport.

The device can be maneuvered with ease by most, since it only weighs 58.1 lbs. One of the largest contributors to its weight are its 196 cc Generac engine and its steel frame. Nethertheless, thanks to its two 10" never-flat wheels, the 8894 remains very easy to manipulate and 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: A safe detergent storage is facilitated by 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 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
