PETKIT Purobot Ultra
Premium AI camera + automatic waste sealing · Reviewed by Drew · amazon.com live, Sept 28 2026
Why it scored a 77
The no-touch flagship: waste is heat-sealed into bags automatically so you never handle a drawer, and a rotating 1080p camera tracks stool shape and clump size per cat, which is why Features leads at 95. Against that, proprietary refill rings cost $10-plus per pack, facial recognition was still beta and inaccurate in Cats.com's 3.8/5 test, there is no low-litter warning, and the 32-inch-deep footprint is huge. At $799.99 list ($749.99–799.99 on sale) with an optional PETKIT Care+ plan for full video history, Value is the softest at 62.

Should you buy the PETKIT Purobot Ultra?
The PETKIT Purobot Ultra is the flagship for owners who want a camera and per-cat health data in the litter box. A 1080p rotating camera with night vision feeds AI facial recognition, so the app logs each cat's visits, stool shape and color, and clump size. It also heat-seals waste into packs automatically. At $799.99 it is the most expensive box we rank, and the proprietary refill rings add an ongoing cost. It is for a data-focused owner, not a first-time buyer.
Where it earns its score
- Features score 95. The highest features mark in the category: camera, AI cat recognition, stool tracking, 20 safety sensors and automatic heat-seal packing.
- Longest bin interval. The 10 L compartment lasts up to about 20 days for one cat, and about 200 days of sealing bags are included.
- Quality scores 88. Second only to the Litter-Robot 4 among boxes here.
- Always-open entry. Cats 3.3 to 22 pounds can walk in without a door, and the cycle is rated at about 36 dB.
What to know first
- Value scores 62. The lowest value mark in our robot litter box rankings. You pay $500 more than the Purobot Max 3 for the camera and sealing.
- Ongoing ring cost. Proprietary refill rings run $10 or more per pack, and there is no low-litter warning.
- Big footprint. About 21 inches wide, 32 inches deep and 24 inches tall, at roughly 32 pounds.
- Warranty is the weakest ViperScore factor. At 55, coverage does not match a $900 price.
Our verdict
The PETKIT Purobot Ultra scores 77, Fair Buy, ranked #7 of 7 robot litter boxes. The ranking is about price, not capability. Buy it if per-cat health tracking through a camera is something you will actually use. Otherwise, the PETKIT Purobot Max 3 at 82 gives you the same brand's core automation for $369.99.
