They have lots of grass in Norway; it seems to grow everywhere.
We're seen many robotic lawn mowers hard at work
You'd think they would have been adapted to trim the grass on the roof.
One could even imagine a brush cutting attachment.
Wishful thinking, I guess. This one got stuck in a tiny patch of mud, so I guess robotic roof trimming is a ways off.
What's wrong with shaggy roofs?
