The sensible pick in the Litter-Robot 5 family: same globe, drawer and weight tracking as the Pro without the cameras. It suits larger cats and multi cat homes better than the Litter-Robot 4, but the LitterHopper add on is listed separately and settings live only in the app.

The EVO is the cheapest way into a Litter-Robot and fits smaller rooms than the Litter-Robot 4 or 5. It is rated for only two cats up to 19 lb, so big cats and busy multi cat homes should look at the larger models. It needs a flat, hard floor to avoid position errors.

What reviewers found

Whisker Litter-Robot 5

Cats.com: Described in the October 2026 roundup as nearly the same as the 5 Pro without cameras, saving $100. Source
9to5Toys: Review of the 5 series found it quieter, smoother and less sensitive to placement on carpet than the Litter-Robot 4, with a better carbon filter. Source

Whisker Litter-Robot EVO

Vetstreet: A veterinarian used it for about two weeks in a multi cat home and praised odor control and automation, but said the Litter-Robot 5 Pro would have suited her household better. Source
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
