PETKIT Purobot Max Pro 2 Review (2026): The AI-Camera Litter Box

The verdict: The PETKIT Purobot Max Pro 2 is the self-cleaning litter box to buy when you want a camera watching over feline health, not only a scale under the drum. It keeps everything that makes the PETKIT PuraMax 2 worth owning, a large 76-litre drum, an 8-litre sealed waste bin good for up to seventeen days with one cat, and automatic cleaning after every visit, then adds a 1080p, 210-degree AI camera that recognises each cat by its face and watches for stool, urine, and yowling signals worth showing a vet. The opening is huge, safety runs to twelve sensors, and it is quiet enough for a bedroom. It sits at the premium top of the lineup, a camera over the litter box is not for everyone, and the health cues are pointers rather than a diagnosis, but for a multi-cat home that wants the most intelligent box PETKIT makes, this is it. Best AI-Camera Litter Box.

Beyond weight tracking

The PETKIT PuraMax 2 already does the hard part well: it self-cleans, it seals odor away, and it tells your cats apart by weighing each one as it steps in. That weight-based identification is genuinely useful, but it has a ceiling. Two cats of a similar size are hard to separate on the scale alone, and a number on a chart cannot show you what a session actually looked like.

The Purobot Max Pro 2 is PETKIT's answer to that ceiling. It is the camera flagship of the lineup, built around the same rotating-drum design but with an AI camera and cat facial recognition layered on top. Where the PuraMax 2 infers which cat visited, the Purobot can see it, and that difference is the whole reason to step up.

The AI camera and facial recognition

The centrepiece is a 1080p camera with a 210-degree wide-angle lens set over the drum, rated IPX5 against splashes and moisture and fitted with a microphone for one-way audio. Through the PETKIT app you get a live look at the box and recorded clips of each visit, so a check from work becomes a glance rather than a guess.

Paired with the camera is facial recognition that identifies up to fifteen cats. Instead of leaning on weight alone, the box matches each visitor to a face and attributes the visit to the right animal, then still cross-checks against the built-in weight sensors. For a multi-cat home with two similarly sized cats, that is a real step up in accuracy over any weight-only box, and it is the foundation for the health tracking that follows.

Health monitoring the camera unlocks

Camera plus weight sensing lets the Purobot watch for things a scale cannot. PETKIT builds in stool monitoring, urine-pH indication, and yowling detection, each logged per cat in the app as a signal to raise with a vet. A change in stool, an off reading on urine, or a cat crying at the box can be the earliest hint of a urinary or digestive problem, often days before an owner would notice anything wrong.

It is worth being precise about what this is. These are indicative pointers, not a medical diagnosis, and PETKIT frames them as veterinary reference rather than a verdict. Treated that way, they are a genuine benefit: an automated box that can nudge you toward a vet visit earlier is doing more than sweeping litter. Compared with the Litter-Robot 4, whose excellent app tracks weight and usage frequency, the Purobot's camera adds a layer of visual and chemical signals the Whisker box does not attempt.

A bigger, easier opening

Cats are fussy about entry, and the Purobot Max Pro 2 leans into that. The opening is about 10.5 by 10.7 inches, which PETKIT rates as forty-three percent larger than the previous generation, and the design is aimed squarely at large, senior, and short-legged cats that find a narrow porthole intimidating. A cat that hesitates at a cramped box is a cat that may start going beside it, so a wide, inviting entry is not a luxury.

Inside sits a 76-litre drum and an 8-litre sealed waste bin, which PETKIT rates at up to seventeen days between empties for a single cat. A multi-cat home will empty it sooner, but the practical effect is the same as the class leaders: scooping turns into an occasional bag change.

Safety and the anti-pinch design

Owners of any rotating box worry first about safety, and the Purobot answers with twelve integrated safety sensors and a patented anti-pinch design. Infrared and weight sensing detect a cat in or near the drum and hold the cleaning cycle, and the mechanism is built so a paw or tail cannot be caught as it turns. As on its siblings, the entrance is designed to stay open so a cat is never shut in.

Odor control and daily use

Odor is what decides whether a box can live in a real room, and the Purobot uses a multi-layer approach: the sealed waste bin isolates clumps the moment they drop, an N50 deodorant cartridge neutralises ammonia, and an N60 air-refresh unit runs to keep the surrounding air clean. Reviewers describe the combination as effective for a heavy-use box, with the cartridges and refills being consumables to re-buy over time.

Day to day it is quiet, rated at around 35 dB, which is genuinely bedroom-friendly for a machine of this size. It connects on both 2.4 and 5GHz WiFi, and the 5GHz option matters here in a way it does not on a plain box, because streaming and recording camera video wants the extra bandwidth. It takes clumping clay, tofu, or mixed litter with granules no larger than half an inch, and like every sifting box it will not tolerate crystal or pellet litter.

Where it falls short

The Purobot's compromises follow from what it is: the most feature-heavy box in the lineup.

The first is cost. This is the flagship, and it sits well above the PuraMax 2 and most rivals. If the camera and its health signals do not appeal, the PuraMax 2 delivers the same core self-cleaning experience for much less.

The second is the camera itself, which cuts both ways. A lens over the litter box is exactly what enables the health monitoring, but a camera in that part of the home is a privacy trade not every owner will accept, and it is one more component that can fail on a machine already dense with electronics.

The rest are the familiar litter-box limits. The health cues are indicative pointers for a vet rather than a diagnosis, so do not treat an app alert as a clinical result. It needs clumping or tofu litter, not crystal or pellet. And the deodorizer cartridges, air-refresh refills, and waste bags are running costs on top of the purchase.

Purobot Max Pro 2 vs PuraMax 2

The honest internal comparison is with its own sibling. The PETKIT PuraMax 2 is the value pick: the same rotating self-cleaning drum, weight-based multi-cat identification, and a low entry, for far less than the flagship. For most homes it is the sensible buy.

The Purobot Max Pro 2 justifies its premium in three places: the AI camera and facial recognition, which separate similarly sized cats far better than weight alone; the visual health signals the camera unlocks; and a bigger opening with a slightly larger waste bin and 5GHz WiFi. If per-cat accuracy and health monitoring are the point, the Purobot is worth the step up. If they are not, the PuraMax 2 gets you the same clean box for less.

Purobot vs Litter-Robot 4

The other natural comparison is the premium mainstream benchmark. The Litter-Robot 4 is the more proven machine, with a long track record, a wide, inviting globe, an eighteen-month warranty, and the polished Whisker app that tracks each cat's weight and usage. For a buyer who values a long support history above all, it earns its place.

The Purobot's counter is the camera. Facial recognition plus a live feed and chemical health signals go beyond what the weight-and-usage Whisker app attempts, and its odor system and large opening are competitive. A shopper cross-shopping the two is really choosing between Whisker's proven pedigree and PETKIT's more ambitious sensing. Owners weighing a third option should also read the Petlibro litter box review.

Who should buy it

The Purobot Max Pro 2 is the right pick for the multi-cat home that wants the most intelligent litter box PETKIT makes and will use the camera and health signals it is built around. It suits owners with two or more similarly sized cats who need reliable per-cat identification, anyone who wants a live look and early health cues over the box, and large, senior, or short-legged cats that benefit from the extra-large opening. Buyers stepping up from the PuraMax 2, or cross-shopping the Litter-Robot 4 but wanting a camera, are its core audience.

Who should skip it

Skip it if cost is the priority, since the PuraMax 2 delivers the same self-cleaning core for much less. Pass, too, if you are uneasy about a camera positioned over the litter box, if you insist on crystal or pellet litter, or if you simply want a reliable self-scooper without the extra electronics and app dependence the camera brings.

FAQ

Does the PETKIT Purobot Max Pro 2 need a subscription? No. The box, the camera feed, and the PETKIT app work without a monthly fee. The only recurring costs are consumables: the N50 deodorant cartridges, N60 air-refresh refills, and waste bags.

How is it different from the PuraMax 2? The Purobot adds an AI camera with cat facial recognition and camera-based health monitoring on top of the weight-based tracking the PuraMax 2 already has. It also has a larger opening, a slightly bigger waste bin, and 5GHz WiFi. The PuraMax 2 remains the value choice.

Can it really tell your cats apart? Yes, more reliably than a weight-only box. It matches each cat to its face for up to fifteen cats and cross-checks against the weight sensors, which is why it copes with two similarly sized cats that a scale alone struggles to separate.

Is the health monitoring a substitute for a vet? No. The stool, urine, and yowling signals are indicative pointers meant as veterinary reference, not a diagnosis. Their value is flagging a change early so you can book a vet visit sooner.

What litter does it take? Clumping clay, tofu, or mixed litter with granules no larger than half an inch. Crystal and pellet litters do not sift correctly and will end up in the waste bin.

Bottom line

The PETKIT Purobot Max Pro 2 is the camera flagship of the lineup, and the camera is the point. On top of a proven self-cleaning drum, a large sealed waste bin, and a quiet, safe mechanism, it adds facial recognition that tells similarly sized cats apart and a set of visual health signals that can send you to a vet earlier. Accept that it is the premium option, that a lens over the litter box is a trade, and that the health cues are pointers rather than a diagnosis, and for a multi-cat home that wants the most intelligent box PETKIT makes, it is the one to buy.
