A pressure washer is a powerful cleaning tool that uses high-pressure water spray to remove dirt, grime, mold, and other debris from surfaces. It typically consists of a motor, a pump, and a nozzle, which work together to create a concentrated stream of water. Pressure washers are commonly used for cleaning driveways, decks, patios, and vehicles, making them popular among homeowners and professionals alike. These machines come in various sizes and power levels, ranging from electric models suitable for light cleaning tasks to gas-powered versions designed for heavy-duty jobs. Accessories like different nozzles and surface cleaners can enhance their versatility, allowing users to tackle a wide range of cleaning projects efficiently.
