Best litter boxes that take standard litter, ranked by published specs
Ranking methodology
Ranked by manufacturer-published data only — waste drawer capacity, warranty — with models missing those figures ranked last. RobotMatchup has not physically tested these units and no position here reflects hands-on use.
A box tied to the maker's own crystal trays or cartridges carries a running cost the sticker price hides. Every model here is one whose maker publishes compatibility with standard clumping litter.
