## What reviewers say

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. (Based on 2 reviews, 2 lab-tested, 2023-03-14–2025-02-25.)

Praised: Near-silent operation; Helpful app with litter/waste alerts and cat activity + weight tracking; Strong odor control, no detectable smell; Roomier, sleeker, smaller design than the LR3.
Flagged: Very high ~$699 price; Cat-detection sensor faults / reliability quirks; Litter gets tracked onto the floor (open design); Short one-year standard warranty; Ongoing cost of frequent odor-filter replacement.
Disagreement: Reliability splits sharply: Engadget (three cats, months of testing) hit three-to-four faults weekly and wouldn't trust it alone for a week, while Reviewed (one cat plus a kitten, ~three weeks) needed to intervene only once. Testing duration, cat count, and cat size likely drive the gap.
