Dust, at least, is not an issue like you suspect. The researchers who developed this technique took the dust from a vacuum cleaner and dumped it on a treated piece of metal; water picks up the dust and then slides right off, so the surface is actually incredibly easy to clean.

Watching the video I thought the thing with the teflon was a bit silly. After all if you wanted to think of something that won't hold water at an angle, wouldn't you think of ordinary glass rather than teflon?
