## What reviewers found

### Petkit PuroBot Ultra

- Cats.com (3.8/5): Six weeks of testing: scooping and sealing worked well, but larger cats would not use it, face recognition sometimes confused two cats, bags tore easily and litter leaked around the edges. [Source](https://cats.com/petkit-purobot-ultra-automatic-litter-box-review)
- Catster (4.9/5): Six weeks with one cat: no litter smell noticed, and the camera helped the tester spot a period of constipation; filling it with litter was awkward and there is no low litter alert. [Source](https://www.catster.com/lifestyle/petkit-purobot-ultra-litter-box-review)

### Petlibro Luma

- Cats.com (4.5/5): Easy setup, quick cat acceptance, quiet raking and a sealed drawer; AI analysis needs a subscription and some owners report weight sensor false detections. [Source](https://cats.com/petlibro-luma-automatic-litter-box-review)
- Tom's Guide: After several months with two cats, the cats used it more than a Litter-Robot 5 placed beside it, and the app flagged when one cat stopped using the box for a week.
