## 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)

### Whisker Litter-Robot 5 Pro

- Cats.com: Named Overall Best in its October 2026 roundup of 38 tested models. [Source](https://cats.com/reviews/best-self-cleaning-litter-box)
- Cats.com (4.6/5): Odor control and sifting matched the Litter-Robot 4; reviewer could not test facial recognition without Whisker+ and questioned whether cameras justify the extra $100. [Source](https://cats.com/?p=112270)
- 9to5Toys: Quieter and sturdier than the Litter-Robot 4 with better odor control; bin full alert sometimes fired at about half capacity and urine was sometimes labeled as solid waste.
