Question about Gardena Clean system

The brush is equipped with a soft brush head ("soft") and is therefore suitable for gentle cleaning of sensitive surfaces. It is recommended for cleaning greenhouses and patio roofs, among other things, which indicates its suitability for sensitive surfaces. Due to these properties, it is also generally suitable for cleaning PV modules, as these also have sensitive glass surfaces that should be treated gently. The handle is also designed for cleaning vertical surfaces such as greenhouses or garage doors, which is ideal for use on PV modules.

Is the brush suitable for glass surfaces?
