Query: Great for only One Cat

I have three cats and purchased this item so the litter box could stay clean while I was at work. Unfortunately, the cats preferred the left side of the box and the "scooper" would jam and not work properly. It became harder to clean than the regular litter box. It is now boxed up in a closet. I don't feel like I can throw it alway because I spent so much one it. There should be a note on the box to let you know this product is not meant for households with more than one cat.
