The GARDENA Maintenance and Cleaning Kit for robotic lawnmowers includes a sander that can be used to clean the lawnmower's contacts of dirt, two types of cleaning brushes that can be used to remove dry grass and dirt from the chassis, a plastic protective cleaning spray, and a special screwdriver that, for example, the owner of the lawnmower can use to change the blades himself. The elements of the set are protected from dust and other contamination by a practical plastic box with a lid.
