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:

  • targeted spot cleaning for hard, unpainted surfaces, reaching elevated areas, and thoroughly removing stubborn stains
  • gentle cleaning of delicate surfaces, and low pressure cleaning of larger areas
  • utilizing cleaning solutions, and rinsing surfaces clean

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

With a 196cc engine powering it, the aluminum axial cam pump of this unit are 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.

Featuring a dual starting mechanism, the Generac engine of this gas-powered pressure washer ensures convenience and reliability: you have the choice between the traditional pull-start mechanism and the practical electric start, providing ease of use. The electric start requires a lithium-ion battery, which is included.

Containing gasoline, the pressure washer's fuel tank can hold a maximum of 0.8 gallon..

Design & Handling

The Generac 8894 is very mobile, due to its hand truck design and approximate dimensions of D24.4 x W19 x H35.5 in. With its strong steel frame, the assembly is built to last, providing stability and safeguarding internal components, even in challenging environments. The handle adds to the 8894 convenience of transport.

At 58.1 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. 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. Upon connecting a soap nozzle, the pressure washer takes over the task of seamlessly combining the detergent with the water flow.
  • Pressure hose: When not in use, the unit allows for tidy storage of the included 25 ft ⌀1/4" high-pressure hose (3100 PSI rating) using a set of convenient hooks, ensuring convenient organization.
  • Spray gun and wand: A side hook enables you to easily store the included PowerDial spray gun and its wand.
