I tried two different ones. First dudn’t function (defective unit). 2nd worked but no so great for my cats. Our large male urinates a lot, so the bag needed replacement after about a day and a half. And it was WAY more difficult to clean inside the thing (big drum shaped inside thing) than just a simple catbox was.
Imagine a President Vance. Compare to a President Waltz. Either would be possible.
