We have this one. My wife bought it or I would have probably tried to go cheap. Does a good job making cleanup much easier and you can preload litter. The cats don't have any problem using it. We have three cats.
I've seen some that actually hook up to your plumbing and wash the litter after every time and this is not it. You still need to empty the litter every few days. This has an app through your phone. I don't know if adding that feature adds any cost but the app doesn't really do anything.
I would recommend, especially if you can get something similar for $200 or $300 with good reviews on Amazon. But if you don't really care about the price, this one will do a pretty good job for you.
