Choosing the right automatic litter box is an important decision for any cat owner. Today's automatic litter boxes do far more than just self-clean—they come equipped with advanced features such as AI-powered health monitoring, multi-cat recognition, behavior tracking, odor control, and automated waste management. These innovations not only simplify daily maintenance but also help you keep your cat healthy and happy over time.
With so many options on the market, finding the perfect automatic litter box can feel overwhelming. This article breaks down the key factors to consider and provides a detailed comparison of three top-rated models from PETKIT, helping you choose the best fit for your home and your feline companions.
What to Consider When Choosing an Automatic Litter Box?
Spacious Design for Cats of All Sizes
Cats need ample room to move comfortably. An automatic litter box with a spacious interior helps reduce mess, improves cleaning efficiency, and accommodates cats of different sizes, including larger breeds.
Smart Health Monitoring: Keep Track of Your Cat's Health
Many cat owners turn to automatic litter boxes not just for convenience, but to gain better visibility into their cat's health. Most automatic litter boxes rely on sensor-based monitoring, using weight and usage data to track how often a cat visits the box and how their weight changes over time. This can help flag potential concerns, such as noticeable changes in visit frequency or sudden weight fluctuations. Now, more advanced, next-generation models, including some PETKIT models such as the Purobot Ultra Automatic Litter Box and Purobot Max Pro 2 Automatic Litter Box, take health monitoring a step further by adding AI camera-based analysis. In addition to weight and usage tracking, these systems can capture stool and clumping images, observe behavior patterns, and detect unusual events such as prolonged visits or yowling during use.
Multi-Cat Recognition
In multi-cat households, accurate multi-cat recognition is important for both daily care and long-term health monitoring. A multi-cat recognition system can distinguish each cat individually, even cats with similar weights. This ensures that every litter box visit is recorded under the correct cat profile, keeping health data such as usage frequency, clump size, and behavioral changes clearly separated. Some automatic litter boxes, like the Purobot Ultra Automatic Litter Box and Purobot Max Pro 2 Automatic Litter Box, use advanced AI recognition to prevent data mix-ups between cats. This allows owners to monitor usage patterns in real time and identify unusual behavior, such as changes in urination or stool, which could indicate potential urinary or digestive issues.
Safety Assurance
Safety is a top priority when choosing an automatic litter box. Modern designs combine structural features and sensor systems to protect your cat. Drum-based designs often use spiral tracks or open-access geometry to prevent pinch points, while horizontal rake systems naturally avoid hazards. Sensors—including motion, weight, and auto-stop—pause cleaning if a cat is nearby. This layered approach ensures reliable protection and gives cat owners peace of mind.
Odor Control
Effective odor control is a key feature of any automatic litter box. Advanced models use a sealed waste bin and deodorizing modules to neutralize odors at the source, preventing unpleasant smells from spreading in your home. Strong odor control ensures a cleaner, fresher environment for both cats and owners, regardless of household size or number of cats.
Quiet Operation
A noisy litter box can disrupt your daily routine and disturb both you and your cat, especially during cleaning cycles. Modern automatic litter boxes are designed to operate whisper-quiet, often as low as 35 dB. This ensures the cleaning cycle won’t interrupt your sleep, work, or relaxation, and makes it easy to place the litter box in bedrooms, living rooms, or other shared spaces without worrying about noise.
Large Waste Bin
A larger waste bin reduces the frequency of emptying and simplifies daily maintenance. Many litter boxes feature bins with 7–10L capacity, enough to hold 15–20 days of waste for a single cat. This is especially convenient for busy cat owners or multi-cat households, allowing for a more hands-off experience and less frequent scooping.
App Control
App control adds a new level of convenience compared with traditional litter boxes. Whether you’re at work, traveling, or relaxing at home, you can check the litter box status, review your cat’s usage patterns, and adjust settings such as cleaning schedules, waste alerts, and health data tracking—all from your smartphone.

Here's how PETKIT's top three automatic litter boxes deliver smarter, safer, and cleaner experiences for cats of all sizes. We'll take a detailed look at the AI-powered, health-focused Purobot Ultra Automatic Litter Box, the reliable and feature-rich Purobot Max Pro 2 Automatic Litter Box, and the affordable, entry-level PuraMax 2 Automatic Litter Box, comparing their features, performance, and suitability for different households.
PETKIT Purobot Ultra Automatic Litter Box
Overview
The Purobot Ultra Automatic Litter Box is PETKIT’s flagship automatic litter box and the world’s first AI-powered model with an integrated camera. It combines cutting-edge technology with a fully automated, hands-free design to make cat care smarter and easier.
Equipped with a 180° rotating AI camera, the Purobot Ultra Automatic Litter Box monitors your cat’s litter-box activity, capturing stool and clump images to help detect early signs of potential health issues such as constipation, diarrhea, hematuria, and other urinary or digestive concerns. Real-time alerts through the PETKIT app keep you informed of your cat’s health and behavior at all times.
Designed with multi-cat households in mind, it features facial recognition to identify each cat and yowling detection to alert you if a cat is in discomfort. With a spacious 70L interior, the Purobot Ultra accommodates cats of all sizes—from kittens to large breeds over 6 months old.
Its fully automated waste management system—auto-cleaning, auto-packing, and auto-bagging—uses a 10L extra-large bin that can go up to 20 days without scooping. A 4-stage odor control system, including a sealed trunk lid, N60 odor eliminator, auto-sealed bin door, and leak-proof bag, ensures your home stays fresh even with multiple cats.
Built with a thoughtful structural design to prevent pinch points and accidental trapping, the Purobot Ultra combines mechanical safety with 20 high-precision sensors for added protection. This layered approach ensures your cat stays safe during every cleaning cycle, while WiFi connectivity lets you monitor usage and health remotely via the PETKIT app.

With real-time alerts sent to the PETKIT app, you can proactively care for each cat in your household.
- Multi-Cat Facial Recognition

Disadvantages
No product is without trade-offs, and Purobot Ultra Automatic Litter Box is no exception. That said, its limitations are relatively clear and largely come down to two practical considerations: price and size.
- Price
The initial price of the Purobot Ultra Automatic Litter Box may feel relatively high compared to standard automatic litter boxes. However, when viewed from a long-term perspective, it offers strong value. Features such as AI-powered health monitoring, fully automated waste disposal, and reduced daily maintenance help save time and effort over months and years of use. For cat owners who prioritize convenience, health insights, and a truly hands-free experience, the price reflects a long-term investment rather than a short-term purchase.
- Size
At first glance, the Purobot Ultra Automatic Litter Box may appear substantial due to its enclosed design. In practice, its footprint is comparable to a typical nightstand and similar to many large traditional litter pans. Measuring 20.94 × 32.20 × 24.09 inches, it fits comfortably in most homes while providing the internal space needed for multi-cat use and cats of larger sizes.
Purobot Max Pro 2 Automatic Litter Box

Frequently Asked Questions
1. Do vets recommend automatic litter boxes?
Yes. Many veterinarians appreciate the health-monitoring features of modern automatic litter boxes. Dr. Sarah Wooten, DVM—an internationally recognized veterinary expert and certified veterinary journalist—specifically recommends the PETKIT Purobot automatic litter box with an AI camera. She notes that its ability to track usage and provide visual data helps cat parents detect changes in their cat’s elimination patterns earlier, offering valuable insights for maintaining overall feline health.
2. What type of litter do I need to use?
All three PETKIT litter boxes featured in this article are designed to work with most clumping cat litters. Their replaceable sifters are optimized for common clumping formulas, helping separate waste efficiently while reducing litter waste over time. For best performance, standard clumping clay or plant-based litters are recommended. Non-clumping, crystal, or silicone-based litters should be avoided unless specifically noted as compatible, as they may interfere with the automatic cleaning process.
3. How often do I need to empty the waste bin?
The frequency depends on the model and the number of cats. For one cat, the Purobot Ultra Automatic Litter Box (10L waste bin) lasts up to 20 days, the Purobot Max Pro 2 Automatic Litter Box (8L waste bin) up to 17 days, and the PuraMax 2 Automatic Litter Box (7L waste bin) up to 15 days. The PETKIT app will notify you when the bin is full.
4. Do automatic litter boxes smell?
Odor control is a key consideration in the design of PETKIT automatic litter boxes, not an afterthought. Rather than relying on simple coverage or frequent cleaning, PETKIT builds dedicated odor control systems into its products. Depending on the model, this includes either a triple odor control system or an advanced four-stage odor control system, combining sealed waste containment, deodorizer modules (such as N50 or N60), and, on certain models, air purification. By sealing waste and actively controlling odors within a closed system, PETKIT litter boxes keep unpleasant smells from spreading and maintain a fresher home than traditional open litter boxes.
