What matters
Check that your cat fits comfortably and that the box has reliable safety sensors. Also weigh litter compatibility, odor control, how often you must empty and clean it, and the ongoing cost of bags, trays or litter.
Who this is for
These picks are for cat owners who want less daily scooping but still plan to check the waste bin and clean the machine regularly. Keep a familiar litter box available while your cat adjusts to a new one.
The picks, one by one
Best overall: PETKIT PuraMax 2 Automatic Litter Box
WIRED names it the best option for most people, citing its compact footprint, easy litter refills and triple odor control. It costs about $300 on Amazon, far less than the premium Litter-Robot 4. The unit logs visits and cleaning cycles in its app, and its sealed waste bin, odor-eliminator attachment and deodorizing spray help contain smells. Its opening rotates upward to make refilling easier, and it works with several clumping litter types. Reviewers note that the app can be cluttered or buggy and the box does not alert you when litter is low. Skip it if your cat is large or dislikes enclosed, tighter entrances.
Good to know: The app can be buggy, and there is no low-litter sensor.

It costs considerably more than the PuraMax 2, but Good Housekeeping and Cats.com praise its reliable cleaning, odor control and multi-cat usefulness. It suits shoppers willing to pay extra for a roomy, polished machine and established app features. Good Housekeeping tested it in several homes and found most cats took to it, though its tester's cats needed about two weeks to transition. The app tracks use and alerts you when the waste drawer needs emptying, and it works with clumping clay litter. Cats.com describes setup as straightforward and the build as solid. It is bulky and still expensive, so skip it if floor space or upfront price is a concern.
Good to know: It takes up substantial floor space and costs several times more than the PuraMax 2.

Good Housekeeping recommends it as its best-value pick and lists it at about $130 on Amazon, the lowest price among these three. Its simple rake-and-tray design offers automatic waste removal without an app or a large upfront spend. After a cat leaves, a sensor starts a rake cycle that moves solid waste into a covered compartment; crystal litter absorbs urine. Good Housekeeping liked the low dust and tracking and the easy setup. Expect to replace the disposable tray and crystal litter regularly, which raises ongoing costs. Skip it if you want to use ordinary clumping litter or are especially concerned about urine odor.
Good to know: It requires proprietary crystal litter and replacement trays, which add recurring costs.
See on AmazonHow we chose
Recent reviewers tested boxes in homes with their own cats, looking at setup, whether cats accepted them, cleaning performance, odor, litter scatter, app controls and waste-bin capacity. WIRED tested its picks for at least a week, often longer; Good Housekeeping also drew on longer-term home use and Danilli read the reviews and tests listed below and compared current prices; it does not take money from brands to pick a product.
