The "Leifheit Dry&Clean" appliance is designed primarily for cleaning windows, but it is not specifically adapted for use upside down on glass balustrades. The handle of the appliance is generally designed for vertical or horizontal use, and using it upside down could make it difficult to hold the appliance in place, especially if the weight of the appliance is not evenly distributed. We recommend that you consult the instruction manual for further details on recommended uses and precautions to be taken when using the appliance.
