The verdict
Why it scored a 79
The quietest major robot litter box at around 30 dB, with an EPA-registered UV-C cycle, per-cat weight tracking and drums in colors nobody else offers, which is why Quality leads at 86. The 20 lb cat limit is low, the app trails Whisker and PetKit, it needs 1 inch of wall clearance, and Casa Leo (renamed from Smarty Pear in 2024) has a shorter reliability record. At $599.99 list with no subscription, Warranty is the softest at 55 with 1 year included and a 3-year extension sold separately.
