This product is like automatic starter for your car when it is 10 degrees outside or automatic locks for the car. Once you got it, you can never imagine any other way. I seriously think I could not do the whole scooping litter again. I had a litermaid and cleaning that thing every few weeks was such a chore. This is so easy. I look at it occasionally because when it runs at the same time as washer and dryer and that can be tricky, but other than that "set it and forget about it."
Yes, it does get litter on the floor but I have a small shark that sweeps of granules then I put them back in the box. I have two older cats and transition was easy.
