"pressure washer"的定义和意义

What is a "pressure washer"?

A pressure washer is a cleaning tool that uses high-pressure water to remove dirt, grime, mold, and other stains from surfaces. It typically consists of a motor or engine, a pump, and a hose with a nozzle that directs the water. Pressure washers are used on a variety of outdoor surfaces, such as driveways, patios, and cars, to clean them quickly and effectively. The high-pressure stream of water makes it easier to clean tough stains and reach areas that are hard to scrub by hand, saving time and effort in cleaning tasks.
