Generac residential power washer give you cleaning power, reliability and -above all- ease of use in an affordable, compact unit you can use to clean everything from patio furniture to driveways and decks. The user-friendly design makes it easy to assemble, connect hoses, move almost effortlessly regardless of terrain, and clean longer and more comfortably.
(Note: Because of the greater risk of injury, we recommend no pressure washer that comes with a zero-degree replaceable nozzle or setting, no matter how well it cleans.)
At 3100 PSI, the Generac 6923 pressure washer is ideal for heavy duty residential cleaning tasks such as concrete and paint prep. The residential pressure washer includes 0-degree, 25-degree, and 40-degree quick-change nozzle tip, as well as a dedicated nozzle tip for soap application. Each nozzle snaps on quickly, limiting the downtime between cleaning tasks. The unit also features an ergonomic spray gun with cushion grip and easy-to-pull trigger which helps to reduce fatigue and improve comfort while completing your cleaning tasks. The 25-foot high pressure hose connects to the back of the spray gun, making it simple to get to hard-to-reach areas without straining.
For maximum cleaning performance, this pressure washer is powered by a powerful Generac OHV horizontal- shaft engine. With a horizontal-shaft engine, the pump is well above the ground at the same level as the engine, making hose connections a snap – unlike vertical-shaft engines where the hose connections are under the engine and more difficult to reach. As an added benefit, this unit features an integrated ½-inch gallon detergent tank. This onboard storage tank holds the detergents needed to clean stubborn stains. Once the detergent is added to the tank, people can easily move around the property. Maneuverability with this pressure washer is easy.
The engine and pump are perfectly balanced over the axle for almost effortless maneuverability. In addition, the 10” never-flat wheels help you move across any terrain. Designed with ease of use in mind, this pressure washer features user friendly controls all in one single location – including on/off, choke and fuel shutoff.
Generac 3100 PSI Gas Pressure Washer Test Results
Generac 3100 PSI Gas Pressure Washer Review
The Generac 6923 is part of the Pressure washer test program. In our lab tests, Pressure washer models like the Generac 6923 are rated on multiple criteria, such as those listed below.
Cleaning: Versatility and efficiency in cleaning a range of surfaces. The better performers have multiple spray patterns that can cover various cleaning chores, from light, superficial cleaning to deep cleaning of concrete, decking, and other hard-to-clean surfaces.
Power: A combination of pressure, measured in pounds per square inch (psi), and flow, measured in gallons per minute (gpm). Higher pressure results in better cleaning of a given surface; coupled with a higher flow as well, you’ll get the job done the fastest.
Noise: A combination of measurements, based on dBA, reflecting the proximity of the operator to the pressure washer. While our Noise score averages measurements taken close by the machine and at the end of the hose’s typical reach, we strongly strongly recommend hearing protection for working close by a gas powered pressure washer in particular.
