What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Litter-Robot 4
Two whitelisted hands-on testers (Engadget, USA Today's Reviewed) rate the Litter-Robot 4 the best self-cleaning litter box despite its ~$699 price. Both praise near-silent operation and the companion app; both flag cat-sensor quirks and the high price. Engadget flags litter tracking; Reviewed flags the short one-year warranty and ongoing odor-filter replacement cost. All six quotes were verified as literal substrings of the fetched review text. (2 sourced reviews, 2 lab-tested.)
Praised: Near-silent operation; Helpful app with litter/waste alerts and cat activity + weight tracking; Strong odor control, no detectable smell.
Flagged: Very high ~$699 price; Cat-detection sensor faults / reliability quirks; Litter gets tracked onto the floor (open design).
