The washable cover is intended for gentle cleaning of cars and motorbikes and is compatible with both the WB 120 and the previous WB 100 model.

Advantages

How to use

Attach the microfibre cover to the rotating brush disc using the hook-and-loop fastener, making sure it sits evenly and securely. Use the WB 100 or WB 120 wash brush according to the washer’s instructions, applying moderate pressure and moving steadily across the surface to avoid concentrated abrasion. After use, remove the cover by detaching the hook-and-loop fastening and rinse or machine wash it at up to 60 °C. Allow the cover to dry completely before reattaching.

Usage recommendations

Use the microfibre attachment only with the specified WB 100 and WB 120 rotating brushes. Do not use on heavily soiled surfaces with sharp grit present; pre-rinse or pre-clean to remove coarse dirt. Wash the cover regularly to prevent dirt buildup and inspect for wear before each use.
