## 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)

### Smarty Pear Leo's Loo Too

- Rover: No noticeable drawer smell after an 11 day absence and the app identified a cat by weight; one cat kept hissing at the cycle and avoided the box. [Source](https://www.rover.com/blog/leos-loo-too-review)
- NBC Select: Used for over six months with one cat in a New York City apartment; the drum stopped when the cat approached, and the drawer filled in about 7 to 9 days. [Source](https://www.nbcnews.com/select/shopping/automatic-litter-box-leo-too-review-rcna189883)
- The Gadgeteer: Odor was much lower than a standard box and the cat adjusted within hours; weight sensing may not work on carpet or soft floors. [Source](https://the-gadgeteer.com/2023/07/15/leos-loo-too-automatic-cat-litter-box-review-dandy-at-dealing-with-the-duty-of-doody)
