The talk of vacuuming up sand was to do with the new track at Bury Metro, where the track was laid with the wrong sort of sand being used. They used a very course grain that doesn't sink well into the very tight weave on this type of astro.
If we removed that sand, we would have replaced it with finer grain sand. The idea was never to use it without sand, just to remove the wrong stuff.....
