I think the whirling brushes are unable to deal with deep snow...like, greater than say 4-6 inches. While most days we get less snow than this, (and with climate change we will rarely get this amount), we get road plows pushing giant piles which they would be unable to manage. They are also less able to deal with ice, which plows don't really deal with anyway.
That being said, they do have a number of the brush vehicles, which they use in DTK. They do work very well, but like most things in our unsustainable wasteful suburbs, we just can't afford nice things.
I assume the brushes only go up to a certain depth as you suggest. I’m not even sure about that depth — 15cm is a lot for a brush. But I’m confident brushes do better at removing the last little bit — a blade can start running on top of an ice layer and leave 2cm behind, or have trouble with any small irregularity in the surface.
I would have thought that they would be the same vehicle, just with a different attachment. Does anybody know if that’s true?
