It would be more useful if you weren't cleaning a clean window and show window results, not only the pad. For me those robots are nothing more than expensive piece of cloth that moves by itself. As you even said that - it is not for cleaning dirty windows 😕
So the exterior of both windows shown had never been cleaned in the 5+ years the house has been built. So there was dirty/grime etc and it did remove it. Inside wasn't cleaned before filming but has been cleaned previously if that makes sense? This is best designed to maintain clean windows!
Such a good question!! I only have square windows so I honestly didn't know. I'm assuming it might make it all the way around but I could also see the bumper triggering it every few inches and slowly going back and forth but eventually cleaning most of that section?;
