What do you do to clean sand and debris from your isle ways.

We are getting a lot of sand and dirt down our isles. I have used a portable blower in the past, but stuff by door gets blown into units. Units get enough dust
as it is. Looking for a different option. Any ideas are welcome.

I have thought about street sweeper, but I don't think they get sand at bottom of doors.

UPDATE: WE HAVE TRIED A LARGE SHOP VAC AND MAINTENANCE MAN IS WALKING THE ISLE VACUUMING UP
ALL THE SAND AND DIRT... WHERE WE ARE GETTING SAND ???

Have you used a dust mop? Those are the best at getting fine particles for me. Street sweeper machines I've used are good for bulky and bigger stuff but always leave small fine stuff behind. As far as where you're getting sand from, are you're close to costal area? In Florida we got it pretty regular, even had little crabs in the aisle occasionally.
