Product Information

Full details

The Kärcher PCL 3-18 is a cordless, battery-operated solution designed for homeowners seeking an efficient way to deep clean wooden decks, WPC, and stone tiles without the hassle of trailing power cords. By utilizing dual rotating brush rollers and an integrated water distribution system, it provides a consistent, high-performance cleaning action that removes moss and surface grime with minimal effort; however, users should note that as a low-pressure device, it is specifically optimized for surface cleaning rather than heavy-duty industrial degreasing.
