Best budget automatic litter boxes under $400, ranked by published specs
Ranking methodology
Ranked by manufacturer-published data only — waste drawer capacity, list price — with models missing those figures ranked last. RobotMatchup has not physically tested these units and no position here reflects hands-on use.
Under $400 the spec sheets get shorter: smaller drawers, fewer published sensor details, and shorter warranties. Models with no published list price are left out of this guide rather than guessed at.
