What reviewers found
homerunPET CS106
- Cats.com (4.2/5): Tested several weeks with two cats; odor was not a problem despite no dedicated odor system, radar sensors were at times oversensitive, and a longhaired cat tracked litter since there is no step or mat. Source
- 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
