Description

Zoom on the Generac 8874

The Generac 8874, a heavy duty pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:

  • spot cleaning of hard, unpainted surfaces and high-reach cleaning
  • cleaning of painted and frail surfaces
  • use of detergent and cleaning solutions

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

Power

The Generac 8874 in use

The Generac 8874

Using a 196 cc engine, its aluminum axial cam pump delivers a pressure of up to 2900 PSI (roughly 48 times more than a standard garden hose) and a flow of up to 2.4 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 6960 Cleaning Units.

The Generac engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.

Gasoline is stored in a fuel tank with a maximum capacity of 0.8 gallon.

Design & Handling

With its hand truck design and approximate dimensions of D24.4 x W18.9 x H35.5 in, the Generac 8874 provides great mobility. The robust and sturdy steel frame offers longevity to the assembly. The rubber-padded fixed handle adds to the 8874 convenience of transport, while offering a comfortable grip.

Most users can maneuver this model easily, as it weighs just 57 lbs. One of the largest contributors to its weight are its 196 cc Generac engine and its steel frame. The 8874 can still be easily manipulated and maneuvered, thanks to its two 10" never-flat wheels.
