I've had the Cat genie for a year and a half now and it is great. My cats adore it because it is so clean! It's great for me because I'm out of the house a lot and I don't have to worry that their litter box will be too dirty for them to use, even if I'm gone for a few days (which is also helpful in getting people to watch my cats, since they don't have to clean a litter box). The most I even have to do with it is clean the water sensor and wipe down the rim above the bowl. So awesome!
