Design & Handling
Enhanced mobility is a key feature of the Generac 7899, 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.

With its 57 lbs weight, this unit offers a manageable size that allows for easy handling by most individuals, enhancing user convenience during operation.

Main Features
The Generac 7899
The Generac 7899's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.
