Introduction
Cats are notoriously picky about their litter boxes, and pet owners often struggle with odor, frequent scooping, hygiene, and health monitoring. Smart litter boxes attempt to tackle these challenges — and the PUROBOT MAX PRO 2 is one of the most advanced in the market. With AI camera, health tracking, multi-cat recognition, and a self-cleaning design, it promises to reduce your maintenance burden while giving you more insight into your cat’s well-being. Below, we dig into its features, specs, benefits, and considerations.

What Is the PUROBOT MAX PRO 2?
The PUROBOT MAX PRO 2 is an automatic, self-cleaning litter box developed by PETKIT, designed for indoor cats (over 6 months old and >1.5 kg). It uses a motorized cylinder to sift waste, a drawstring waste packing system, and an on-board AI camera to monitor each litter box visit, detecting metrics like urine pH, stool consistency, and even “yowling” sound events.
The system connects via Wi-Fi (2.4 GHz / 5 GHz) to the PETKIT app, giving remote alerts, usage logs, and health data for each cat (even in multi-cat households).
In short: it’s a premium, feature-rich litter box that goes beyond waste disposal to health monitoring and data tracking.

What’s New Compared to Prior Model (MAX PRO)
- The entry has been enlarged by ~43% to facilitate easier use by large or short-legged cats.
- More robust health tracking: captures more granular data (urine pH, stool logs, detecting “yowling” for signs of discomfort)
- Better multi-cat recognition: combining facial recognition + weight sensor data to avoid mixing data between cats with similar weight.
How It Works: Operation & Workflow
Here’s a simplified step-by-step of how the PUROBOT MAX PRO 2 operates and what the user experience looks like:
- Cat enters through the entrance, uses the litter box as usual. The AI camera records the visit.
- Sensors detect when the cat exits (via weight / proximity sensors). The cylinder then rotates to sift out clumps and waste.
- Drawstring waste packing: the sifting leads waste to a sealed bin. With a pull of a drawstring, it packs the waste hygienically in a bag. Up to ~17 days of use for a single cat without manual scooping.
- Health analysis & app updates: The app receives the captured data (urine pH, stool quality, visit frequency etc.), and presents it in timeline / record format. You also receive push notifications (e.g. abnormal readings).
- Multi-cat handling: Even if multiple cats use the same box, the system differentiates them by facial recognition and weight data, attributing data to the correct cat.
- Privacy / camera control: If you prefer privacy, you can disable the camera entirely or schedule “off hours.” All data is encrypted.
- Maintenance & cleaning: The unit is detachable for easier cleaning. The cylinder is “leak-proof” (360° seamless base) to minimize fecal streaking. The app also has modes (e.g. “Waste Covering Mode”) to further reduce streaks in case of soft stool.
- Continuous updates: Firmware upgrades are delivered OTA via the PETKIT app.
Benefits & Advantages
Here are the key benefits PUROBOT MAX PRO 2 that set this device apart:
- Reduced Scooping Effort: With the drawstring waste bin and automated sifting, you can skip manual scooping for up to ~17 days (for one cat) under normal usage.
- Health Monitoring & Early Alerts: The AI camera monitors urine pH, stool conditions, and even vocalizations (yowling), giving you early clues of issues like urinary tract disease.
- Multi-Cat Friendly: Matching each cat’s visits to the correct profile ensures that health data remains accurate, even for cats with similar weight.
- Quiet Operation & Safety: The system works quietly (≈ 35 dB), includes anti-pinch design, 12 sensors, and keeps the entrance open when rotating to avoid accidents.
- Larger Entry for Accessibility: The expanded entrance makes it more usable for older, larger, or shorter-legged cats.
- Privacy Control: You have full control to disable or schedule camera usage, and data is encrypted.
- OTA Firmware Updates: The unit can receive enhancements over time.
- Minimized Odor / Leakage: The cylinder and bin designs are built to reduce leaks and odor, plus built-in deodorization systems.
Limitations / Considerations
No product is perfect. Here are a few potential drawbacks or points to consider:
- High Cost: The listed price is $699.99 — this is a premium device.
- Size & Weight: It is a relatively large, heavy unit (≈ 11 kg), so placement and movement may be a hassle.
- Requires Flat Hard Surface: For accurate weight measurements, the unit must sit on a hard, level surface (not carpet). Also needs some clearance (5 cm from walls).
- Litter Constraints: It works with ~99% of clumping litters, but particles must be ≤ 12 mm in length. Very fine or very coarse litters might underperform.
- Privacy / Camera Concerns: Even though you can disable the camera, some users may still feel uneasy about a camera in the litter box.
- Transition Period for Cat Adjustment: Some cats are wary of automatic litter boxes. Training / patience may be needed. The manufacturer suggests placing the new box in the same spot, mixing old litter, and gradually allowing the cat to adapt.
- Capacity Limits in Multi-Cat Homes: The 17-day “no scooping” estimate is for one cat; in multi-cat homes, waste accumulation will be faster, reducing that duration.
- No Rotating / Panoramic Camera: The camera is fixed (non-rotating), designed specifically for litter box view (not wider room monitoring).
- Sensor / Technology Failures: As with any smart device, firmware bugs, sensor drift, or connectivity issues may impair functionality (e.g. failure to record or misclassification).
Use Cases & Ideal Users
This product PUROBOT MAX PRO 2 is especially suited for:
- Busy pet owners who want minimal daily maintenance of litter boxes
- Multi-cat households who want individual health data per cat
- Cats with urinary / digestive health concerns (because of the extra monitoring)
- Owners who appreciate smart devices & IoT
- Homes with space for a large litter unit on firm flooring
It might be less ideal for:
- Very small homes or tight bathrooms with little floor space
- Owners who prefer low-tech, low-cost litter solutions
- People uncomfortable with having a camera near cat activities
Pricing & Value
The listed sale price for the PUROBOT MAX PRO 2 is US$699.99. CHeck NOW!
Given the advanced features and health tracking, it positions itself as a premium product. The cost may be justified for multi-cat households or owners who value health insights and automation. Conversely, for single-cat households with simpler needs, a less expensive smart litter box may suffice.
When evaluating value, consider:
- How much time you spend scooping / cleaning now
- Potential health issues (and veterinary costs) avoided by early detection
- Longevity of device (durability, firmware updates)
- Ongoing consumables (waste bags, replacement sifters, cat litter)
Conclusion & Verdict
The PUROBOT MAX PRO 2 is a highly ambitious, feature-rich smart litter box that goes beyond simple self-cleaning. Its AI camera and health tracking features push it into the territory of “wellness device,” offering insights that most litter boxes don’t. For households with multiple cats or owners who want data-driven oversight of their pet’s health, it’s among the top-tier options available today.
However, its high price, size, and technology dependency mean it may not be for everyone. If you decide to get one, allow your cat time to adjust, ensure proper placement, and take advantage of the privacy and safety features in the app.
