I was super excited about this product as to what more could you want then to have a self cleaning liter box!!! But it doesn’t keep the older control down like it should. The rake gets stuck and I’m afraid it’s gonna break. If it breaks there’s no way of even replacing the rake at all. Gotta check it after a couple days to help clean it because it’s like the box can’t keep up with all the maintenance. The noise level is very minimal. Over all not happy with the product as I thought I would be.
