This thread isn't yet old enough to qualify as a zombie, so...
I keep seeing the word "plastic" in reference to the moving (and/or most visible) parts of these systems. Almost always in a pejorative manner.
Given the extreme expense of these systems: why not a brass or bronze option, especially on high-wear items, such as gears?
I can see the need to stick to plastics for moving cleaners - they do need to be buoyant.
But a system which sits in one place and simply (maybe) pop-up?
Has any thought been given this?
