This is the one I use. Like someone else said, it is powerful enough to get the poop but not suck up the fleece. I usually use the crevice tool and it doesn't suck up the hay either. It will grab a piece of hay but then I pull it off and put it in the hay tray. It usually will get all the poos without having to empty it and I just use a little broom to brush the hair and small hay pieces off the filter. I think I paid $20 for it at Wal-Mart.
