Yes, window cleaning robots such as the Ecovacs Winbot W1 Pro can also orientate themselves on frameless window panes. The Winbot W1 Pro has Anti-Flare Edge Detection technology, which allows it to recognise edges and adjust the cleaning path accordingly, which also makes it possible to clean frameless windows. However, it is recommended that there is a minimum distance of one centimetre between the panes so that the edges can be reliably detected.
