Have you tried taking a net and pulling it backwards to swirl the water and get them off the floor and then scoop them up? A lot of people try pushing them with the net to get them in and that rarely works for me. If you have two people one could brush to swirl them up (or get in if you don't have two handles) and the other person can catch them in the net?
