I haven't tried it yet, but it could work. I definitely agree with Stardustone. Since skylights get dirty more quickly, you should remove the worst of the dirt first.

Of course it works there too! But whether the window is cleaner than before is highly doubtful. You must use the robot once a week so that the windows don't get too dirty. Because it totally fails with coarser dirt!

Yes, it works on the roof, but not underneath. If the conservatory has windows with bars, these are of course an obstacle. The robot cleans with a microfibre cloth and not with water. There is a risk that the glass will simply smudge if it is very dirty. The robot works best when the windows are already clean!

Yes, that is not a problem. The robot cleans normal windows by sucking itself in, so to speak. It lifts them up vertically. As long as the power cable is long enough to move the glass all the way down, it should work.
