I've tried all kinds of methods now and no matter what I do, the window stays dirty. This robot doesn't clean, it just pushes the dirt and spreads it evenly across the window. It also leaves very noticeable streaks that make the whole mess even more visible. I've tried every possible combination of dry and wet rags, even wet the window beforehand. Nothing works, always the same result. A complete waste of money. Useless. avoid it
