The Crystal Pro is a cheap entry to self cleaning with standout odor control from sealed crystal trays. The trays are the real cost, about $840 over three years for one cat at Walmart prices. It is a tight fit for big cats and has no app.

$400Check price at Amazon →

The most compact and affordable box here from an established brand, with a useful app and quick support. It suits small to medium cats in tight spaces; larger cats, frail cats who struggle with the 12 inch step, and owners who hate refill costs should look elsewhere.

What reviewers found

PetSafe ScoopFree Crystal Pro

TechnoMEOW: About a month with one 11 lb cat: visitors could not smell it at the 30 day mark, but the cat fit the hood just barely and some crystals tracked out. Source
NBC Select: The writer used two Crystal Pro units; clumps got stuck in the rake and each unit broke or malfunctioned after about six months. 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
TechnoMeow: Most compact automatic box the reviewers tried; strong odor control; drawer fills fast with three or four cats. Source
