Advantages

The device uses an innovative nylon brush with specially aligned bristles to remove superficial moss and weeds without aggressive scraping. A 360° rotatable hemisphere at the cap supports an ergonomic working posture to reduce bending and kneeling. The bristle ring can be replaced quickly without tools thanks to the new locking system, and the tool’s compact, lightweight design improves portability and user comfort.

How to use

Hold the unit at a comfortable angle using the proximity assist hemisphere to maintain an upright posture and guide the rotating nylon brush along the surface to remove dry moss and weeds. Work in overlapping passes and avoid excessive pressure—let the brush do the work. Replace the bristle ring when wear reduces cleaning performance by unlocking the ring with the tool’s quick-release mechanism; no additional tools are required.

Usage recommendations

For best results, use the Kärcher WRE 18-55 on dry moss and weeds; allow recently watered or damp areas to dry first. Wear appropriate eye protection and avoid working on very uneven or loose surfaces. Store the battery separately and follow Kärcher’s battery care instructions to prolong runtime and service life.
