High-pressure washers, also known as pressure washers, are powerful cleaning tools that use high-pressure water jets to remove dirt, grime, and stains from various surfaces. They are commonly used for cleaning driveways, decks, vehicles, and outdoor furniture. The pressure is generated by an electric or gas-powered motor, which forces water through a narrow nozzle, increasing its speed and pressure. These machines come in different sizes and pressure ratings, making them suitable for both residential and commercial use. Users can adjust the pressure settings and switch nozzles to accommodate different cleaning tasks. Safety precautions, such as wearing protective gear, are essential when operating high-pressure washers to prevent injury.
