I absolutely recommend this litter box to any thinking about getting an automatic one. It works well, is easy to use with the app, easy to clean and the safety feature of it shutting off when one of my cats goes to enter is great! I have four cats and two of these and my cats absolutely love them. The removable tray feature saves time cleaning and I typically only have to wipe the inside down once a week to once every other week depending on my cats and add litter to it twice a week. It is also very quite, I have one in my bedroom and typically don't even hear it during the night anymore, typically only awaken if all 4 cats happen to use it back to back and it runs longer than normal. It's a great investment and will save you time and money in the long run!
