Summary
The most practical automatic litter box for most people — triple odor control, a rotating top-fill design, and solid app tracking at a lower price than the competition. WIRED calls it the best basic option for most people.
The only automatic litter box with a built-in 1080p wide-angle camera and AI multi-cat face recognition. WIRED named it their current #1 pick for its compact design and health-monitoring capabilities.
Pros
- Triple odor control: sealed waste bin, odor-eliminator attachment, and citrusy deodorizing spray after every cycle
- Globe rotates so fill hole faces up — easiest litter refill of any model tested
- App logs every use, duration, cleaning cycle start/end, and deodorizing spray events
- Weight displayed on front panel at every cat visit
- More compact footprint than Litter-Robot 4
- Built-in 1080p camera with 210-degree view, night vision, and audio recording
- AI multi-cat facial recognition tracks which cat used the box
- 43% larger opening than previous model, fits cats up to 22 lbs
- Self-sealing waste bag stores up to 17 days of waste for one cat
- Works on both 2.4 GHz and 5.0 GHz Wi-Fi networks
Cons
- App is cluttered with ads for other Petkit products
- No automatic litter-level sensor — must manually check or set reminders
- Smaller interior space than Litter-Robot 4
- No camera or advanced health tracking without upgrade
- App is overcrowded with ads for other Petkit products
- Cat recognition becomes unreliable once free Care+ subscription expires
- Camera is not movable or adjustable
- Ongoing subscription cost for full Care+ features ($4–$12/month)
- More expensive than the Litter-Robot 4
Our take
The PuraMax 2 is the sweet spot: it smells better than almost anything else tested, costs less than the Litter-Robot, and the rotating fill hole is genuinely smarter design than anything Whisker offers.
If you want to actually monitor your cat's health — not just automate scooping — the Purobot Max Pro 2's camera and AI tracking make it the most informative litter box you can buy right now.
