This thing pays for itself in a day I swear! You don't have to think about it, it does ALL the work for you. It must be maintained of course cleaned onece and a while. The best part of it is the customer service. They are there for you with ANY and All questions right over the phone. They keep track of all your iissues and know it is you when you call(same#). They are always nice and understanding. It is sooo worht it. You can hook it up in your laundry room or spare bathroom. I am grateful for CatGenie simplifying my life. Yay No More Litter Ever !!!!
