## 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](https://technomeow.com/petkit-purobot-max-pro-2-review/)

### 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)
