What reviewers found

PETKIT Purobot Max Pro 2

TechnoMeow: Camera helped monitor a senior cat with a vestibular condition; odor control excellent; sensors unreliable on carpet so manual scoop mode was used. Source

Whisker Litter-Robot 5

Cats.com: Described in the October 2026 roundup as nearly the same as the 5 Pro without cameras, saving $100. Source
9to5Toys: Review of the 5 series found it quieter, smoother and less sensitive to placement on carpet than the Litter-Robot 4, with a better carbon filter. Source
