Consumer Reports Tests Cat Litter Boxes: Litter Robot 4 Wins Editor's Choice

other · 2026-08-06

Consumer Reports assessed various cat litter boxes based on their cleanliness, feline acceptance, and overall design. The Whisker Litter Robot 4, priced at $699, earned the Editor's Choice title due to its self-cleaning capability, although its dimensions (22" wide, 27" deep) and inconsistent cat acceptance were noted as limitations. The WoofiGo Stainless Steel Cat Litter Box, available for $55.99, was recognized as the runner-up for its non-stick design but faced issues with seam leakage. For budget-conscious buyers, the Amazon Basics Large Cat Litter Box at $18.99 was deemed the best choice, whereas the Arm & Hammer Sifting Litter Box ($19.99) received criticism for being messy. The PetSafe ScoopFree Pro ($142.49) fell short on automation, and the Van Ness Pets EZ Clean Jumbo ($44.99) was durable but less favored by cats.
