## What reviewers found

### PetPivot AutoScooper 11

- 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](https://www.petsradar.com/pet-tech/petpivot-autoscooper-11-review)
- The Gadgeteer: Easy setup and both modes worked, but the reviewer's cats never adopted it; noted poorly fitting bags and that the unit restarts in auto mode after power loss with a 30 minute delay. [Source](https://the-gadgeteer.com/2025/05/03/petpivot-autoscooper-11-litterbox-review/)
- 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](https://cats.com/?p=114625)

### 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](https://cats.com/reviews/best-self-cleaning-litter-box)
- 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](https://www.irishtimes.com/technology/consumer-tech/review/2026/10/03/litter-robot-4-review-fed-up-with-scooping-cat-litter-try-this/)
- CNN Underscored: Drawer needed emptying about once a week with two cats; quieter than the Litter-Robot 3; cats took about a week to adjust. [Source](https://amp.cnn.com/cnn/cnn-underscored/reviews/litter-robot-4-review)
