What reviewers found
PetPivot AutoScooper 11
- Cats.com (4.2/5): Two medium cats used it within minutes and odor was well contained; a 17 lb cat could enter but not turn comfortably. Review names the PetPivot AutoScooper without a version number; its 10 L drawer and 3 lb minimum match the AutoScooper 11. Source
- PetsRadar: Called it a good entry level box; manual mode suited an anxious cat, the mat cut tracking, liners lasted 5 to 10 days, but the cord was short. Source
Whisker Litter-Robot 4
- Cats.com: Runner Up in the October 2026 roundup; reliable and well built, but the smaller litter bed may not suit large cats. Source
- The Irish Times: Quiet, no smells and a clean tray in a home test; sensors stopped the drum when a cat entered; app cat ID was less accurate for cats of similar size. Source
