## What reviewers found

### Neakasa M1 Lite

- TechnoMEOW: Ran daily for weeks in a multi cat home with no jams or incomplete cycles; odor stayed controlled near a full bin, and it stopped immediately when a cat re entered mid cycle. [Source](https://technomeow.com/neakasa-m1-lite-review-open-top-litter-box/)

### Oneisall Ease S1

- Tom's Guide: Month long test with two cats. Sifted 5 min after each visit with no buildup in corners and came apart in under 20 s. One cat avoided it for most of a week until used litter was mixed in, and the bin sensor was overly sensitive. [Source](https://www.tomsguide.com/home/i-handed-over-litter-duty-to-a-robot-for-a-month-and-my-cats-had-opinions)
- Notebookcheck: About a month of use: very quiet (spec sheet under 45 dB), kept the box clean 99% of the time, but got stuck a few times and needed a power cycle, and the dirty bin sensor sometimes false triggered on the bag. Oneisall supplied the sample. [Source](https://www.notebookcheck.net/Oneisall-Ease-S1-auto-litterbox-review-Looks-as-good-as-it-performs.1261900.0.html)
- Reviewed: Tested for weeks: the reviewer's cat and a friend's cat refused it, but two of three cats in another home used it without issue. Cleans itself well and is easy to wash; the entry is too high for many cats and the footprint is large. [Source](https://www.reviewed.com/pets/content/oneisall-ease-self-cleaning-litter-box-review)
