It is easier to keep cleaner than gravel. Food and poo kind of fall in between the gravel and get stuck there, but any debris that falls on top of the sand kind of just sits on top which makes it pretty easy to get out of there. I usually hover my airline tubing and inch or two away from the sand and it picks up whatever is laying on top of the sand with minimum sand getting removed.
