- 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)

- TechnoMEOW: Used for a couple of months with three or more cats; setup was quick, but a mat edge caused a position fault error and app disconnects were more frequent than on the Litter-Robot 4 until a firmware update. [Source](https://technomeow.com/litter-robot-evo-review/)
