What reviewers found
PetSafe ScoopFree Crystal Smart
- Tom's Guide: A cat adopted it within a day or two; no extra odor after a month; the tray filled in about 30 days after 20 rakes, and waste sometimes stuck to the rake. Source
- TTPM (4.5/5): Used at home with cats and a dog; liked the automatic raking and activity alerts, but notes the app cannot tell which pet used it and the tray is thrown out each time. Source
PetSafe ScoopFree SmartSpin
- Cats.com: Best Budget in the October 2026 roundup; does not auto empty litter and the raised entry may deter some cats. Source
- Cats.com (3.6/5): Month long multi cat test: quiet and easy to deep clean; smaller cats used it more than larger ones; frequent customer reports of technical problems. Source
