Best automatic litter boxes, ranked by published specs
Ranking methodology
Ranked by manufacturer-published data only — waste drawer capacity, maximum cat weight, warranty — with models missing those figures ranked last. RobotMatchup has not physically tested these units and no position here reflects hands-on use.
Waste drawer capacity sets how long you can leave it between emptyings, the published cat weight range says whether your cat triggers the cycle at all, and the warranty shows how long the maker stands behind a motorised box.
