Not sure if the current version has the fix, but the web version on this page is still not working unless you hold down the Q key.
EDIT: I take that back a little, it does seem to work on some sand, but not others. Like the sand that is stuck to the wall gets sucked without pressing Q, but little small spots in corners and larger piles do not, you have to press Q for those. I am at 100% and just cleaning up piles I find, so maybe that has something to do with it?
