What reviewers found
homerunPET CS106
- TechnoMeow: Tested with five cats, two near 15 lb; cats adapted at once, noise barely noticeable, sensors stopped the cycle when the tester came close; filter swap took about 20 minutes and app pairing needed a manual retry. Source
- CGMagazine (9): Tested a few weeks with two cats; no odor after cycles, cycle inaudible from about 5 ft, reinforced liner held up; one app glitch when too many commands were sent. Source
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
