Do not buy
Do not buy. It's the worst. It's not auto. It makes a mess. It's so hard to clean and awkwardly big. It does not work. You have to pay to return. This is the worst thing ever created. I hope the creators and sellers get shingles. That's what it feels like to own this box. I had to also wait months for it and was not told I would. Everything i got with the box is broken/doesn't work either. I watched the videos, followed directions, and tried 5 kinds of litter. It takes longer to use this then jusr regular scooping. And trying to clean it well is impossible. This will be the bane of your existence. With this level of cost just biy a nice robot one.. Honestly better to just use a plain old 5 dollar box. At least you can clean those.
