Leo's Loo Too is a large drum box that testers credit with strong odor control thanks to its UV light and carbon filter. It is pricey and bulky, and one Rover tester's cat hissed at the cycle noise and avoided it. Keep a backup box until a nervous cat adjusts.

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.

What reviewers found

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
  • 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
  • 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

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
