The verdict
Why it scored a 82
The only major open-top robot litter box, which makes it the option for large, senior or globe-averse cats, with per-cat weight tracking, a roughly 14-day waste bin and a free app with no subscription, which is why Features leads at 86. Complaints are the tall 13.9-inch step-in (a step is sold separately), urine leaks at mat seams, false bin-full alerts, and the fact that the open top does not keep out dogs or kids. At $549.99 list (typically $380–430 street), Warranty is the softest at 66 on a 2-year term.
