[Scuderia_Turini]

Every time I see someone showing one of these, I wonder why a manufacturer has not produced one. (I know there was a small manufacturer who did offer one but it vanished quickly)

The IKEA lint-rollers are a global product these days so one based on those would be quite popular.
If I recall correctly, the offered unit could automatically run on batteries or track-power to cover situations where the track is really dusty/dirty.
