Battery-powered pressure washers provide cord-free, fume-free operation for spraying jets of water to loosen and remove dirt, grime, rust, and other deposits from pavement, buildings, and equipment. Also known as cordless power washers, they enhance the cleaning power of detergents while reducing or eliminating the need to scrub surfaces. They require no fuel supply, operate in areas without access to wired power, and eliminate the tripping hazard of a cord. These pressure washers are powered by batteries of a compatible platform and matching voltage. The batteries require recharging or replacement when depleted.
