Okay, so now Im shopping for the pool like I shop for the pups. But I dont understand the hairnet dealies? I understand why you would use them, but I dont know how they would work. If you put a hairnet over the top of the basket, isnt it just going to float and not catch stuff? Im probably missing something here (ya think???). Maybe someone can give me a highly technical scientific explanation (not) on how to make these nets work.
