Gas-powered pressure washers have a gasoline-fueled engine that produces consistent, all-day running power for spraying jets of water to loosen and remove dirt, grime, rust, and other deposits from pavement, buildings, and equipment. Also known as gas-powered power washers, they enhance the cleaning power of detergents while reducing or eliminating the need to scrub surfaces. They operate in areas without access to wired power and have no batteries to recharge or cords to manage. Their engine requires refueling, regular maintenance, and winterizing for storage.
