Game changer. 
This took a bit of time to put together and set up but completely worth the patience and learning you'll need to get it going. It comes with a QR code for instructions. After putting it together you need the App. The litter box only connects to 2.4 wifi NOT 5g Internet - but when it's set up it's fairly automatic. The app is cool. It tells you how often your cat has used it. Personally, I don't see myself using the app after the first couple of days. 
A learning curve I found is you have to push the 'add' button before loading litter because it senses a cat is in there and won't work, if you skip this step. 
I have two cats and they immediately took to it. They're a bit jumpy when it self cleans but it senses when they're in there and waits 3 minutes. 
The self clean is AMAZING. 
I'd recommended the clumping litter to remove urine bits, too.
