The Purobot Max Pro 2 is the better product — WIRED's current #1 pick for good reason — because the 1080p camera and AI cat recognition turn a litter box into an actual health tool. But that advantage collapses the moment your free Care+ trial ends and the cat recognition gets unreliable, which means you're effectively paying $4–$12/month forever to use the feature that justifies the premium. The PuraMax 2 has no such trap: triple odor control, the cleverest litter-refill design tested, and a lower price make it the smarter buy for anyone who doesn't need a camera in their cat's bathroom.

The Purobot Max Pro 2's built-in 1080p wide-angle camera with night vision and audio isn't a gimmick — it's the only way to know if your cat is straining, spending too long in the box, or avoiding it entirely. That's genuinely useful health data. The PuraMax 2 gives you weight and visit duration in the app, which is decent, but it's a spreadsheet compared to a live video feed.
The Purobot Max Pro 2's killer feature — AI multi-cat facial recognition — becomes unreliable once the free Care+ subscription expires. WIRED specifically flagged this: the app started confusing cats after the trial ended. That means you're looking at $4–$12/month indefinitely to use the feature that separates this box from everything else. The PuraMax 2 has zero subscription requirements — every feature works forever out of the box.
The PuraMax 2 runs a three-stage odor system: a sealed waste bin, a dedicated odor-eliminator attachment, and a citrusy deodorizing spray that fires after every single cleaning cycle. The Purobot Max Pro 2 relies on its self-sealing waste bags to contain smell, which works well for waste storage but doesn't address the ambient odor inside the globe between uses. If your litter box is in a living space rather than a utility room, the PuraMax 2 wins this fight.
The Purobot Max Pro 2's opening is 43% larger than its predecessor and rated for cats up to 22 lbs — if you have a Maine Coon or a chunky tabby, this matters immediately. Its self-sealing waste bag also stores up to 17 days of waste for a single cat, meaning you're touching the waste drawer roughly twice a month. The PuraMax 2's smaller interior and standard waste bin mean more frequent interaction for owners of large cats or anyone who hates litter chores.
