Having an automatic litter box is a game changer, however there are some kinks with this one that make me unable to give 5 stars. My two cats started using it within days, so no complaints there but I'm not sure if I received a faulty one or not. Small litter clumps leak out the left side into the cover, so I'm constantly having to remove it and clean it. And sometimes clumps don't sift out and get stuck cycle after cycle. There's also been a few instances of the clear sifter tray thing not closing properly after the cycle and I have to manually push it to snap back.

I've taken it apart and rebuilt it and still the same issues.
It gets dirty quite quickly so l've been vacuuming / picking up clumps that leak, and wiping down the walls and outside with clorox wipes. So it takes some of the work out of a normal litter box, but it's still a pretty high maintenance one to upkeep especially since mine isn't seeming to seal / hold in the clumps properly.
