How We Compared Automatic Cat Litter Boxes
Rather than ranking products simply by popularity, we looked at several practical factors:
- Cleaning performance: How effectively the system separates waste from clean litter.
- Cat accessibility: Entry design, interior space and suitability for different cat sizes.
- Safety features: Sensors and mechanisms designed to stop cleaning cycles when a cat is detected.
- Odor management: Waste containment and odor-control systems.
- Smart features: Apps, usage tracking, cameras and notifications.
- Maintenance: Waste capacity, litter requirements and how often owners need to intervene.
- Value: Features and usability relative to the product’s current price.
No automatic litter box completely eliminates maintenance. Cats still need a clean environment, litter needs to be replenished, and the machine itself needs periodic cleaning.
PETKIT Purobot Max Pro 2 — Best for Advanced Smart Features
The PETKIT Purobot Max Pro 2 is a strong choice for cat owners who want an automatic litter box with extensive monitoring features.
WIRED currently lists it as its best automatic litter box after testing a dozen models. The publication highlights its built-in 1080p camera, 210-degree viewing angle, multi-cat recognition, usage tracking and health-related monitoring features.
Why Choose It?
The Purobot Max Pro 2 goes beyond automatic cleaning by adding connected monitoring. Its camera and app are designed to give owners more information about individual cats and their litter-box habits.
Best For
- Multi-cat households
- Owners who want detailed monitoring
- Technology-focused pet owners
- People willing to pay for advanced features
Limitation
The additional technology comes with a premium price, and owners who simply want automatic waste removal may not need all of its smart features.
Whisker Litter-Robot 4 — Best for App Experience
The Whisker Litter-Robot 4 remains a strong choice for owners who prioritize a mature connected experience.
WIRED describes its app as intuitive and notes that it can track usage and weight, monitor litter and waste levels, and provide notifications. The publication also notes limitations including a difficult-to-fill opening and sensors that can become problematic over time.
Whisker’s European website currently lists the Litter-Robot 4 from €799 and shows thousands of product reviews on its own store.
Best For
- Owners who want an established connected system
- Multi-cat households
- People who value app-based monitoring
- Buyers looking for a premium product ecosystem
Limitation
The price is substantially higher than many basic automatic litter boxes.
PETKIT PuraMax 2 — Best Basic Automatic Option
The PETKIT PuraMax 2 is aimed at owners who want automatic cleaning without moving all the way into the most expensive smart litter-box category.
WIRED currently describes it as its best basic automatic litter box for most people. The publication highlights its relatively compact design, easy litter refilling and multiple odor-control features.
Best For
- First-time automatic litter-box buyers
- Owners who want a relatively straightforward system
- Smaller homes where footprint matters
- Owners who want odor management
Limitation
Despite being a more basic option, it is still a significant purchase compared with a traditional litter box.
Homerunpet CS106 — Best for Larger Cats
The Homerunpet CS106 stands out when interior space and capacity are priorities.
WIRED lists it as its choice for bigger cats and reports a 106-liter overall capacity, with an 8-liter litter reservoir and a 4.5-liter waste reservoir. The tested model supports cats weighing up to 20 pounds.
Best For
- Large cats
- Multi-cat homes
- Cats that dislike enclosed spaces
- Owners who prioritize capacity
Limitation
Its large footprint can make placement difficult, particularly in smaller homes.
Petlibro Luma — Best Open-Top Smart Option
The Petlibro Luma is an interesting choice for owners who want an open-top design combined with advanced monitoring.
Tom’s Guide reported a three-month test with two cats and highlighted the Luma’s open design, integrated camera, AI features, cat identification, activity tracking and health monitoring.
The open design may also make it more appealing to cats that are uncomfortable with enclosed litter boxes.
Best For
- Cats that prefer open spaces
- Multi-cat households
- Owners interested in cameras and monitoring
- Smart-home enthusiasts
Limitation
Tom’s Guide noted that its smaller waste drawer can fill faster than some competitors.
PetSafe ScoopFree Crystal Pro — Best for a Simpler Setup
The PetSafe ScoopFree Crystal Pro is worth considering for buyers who want automatic cleaning without paying for the most advanced connected systems.
Forbes Vetted included the ScoopFree Crystal Pro among its recommended automatic litter boxes and described it as a budget-friendly choice compared with its premium picks.
Best For
- Budget-conscious buyers
- Owners who prefer simpler technology
- Single-cat households
- People who don’t need extensive app features
Limitation
Crystal-based systems can involve ongoing consumable costs and may not be the best fit for owners who prefer conventional clumping litter.
Neakasa M1 Plus — Best Open-Top Design
The Neakasa M1 Plus is particularly interesting for owners who want an open-top automatic litter box with a spacious design.
Neakasa lists the M1 Plus with a 7.17-liter litter capacity and an 11.23-liter waste-bin capacity. The manufacturer specifies compatibility with cats from approximately 1 to 15 kg and lists six pairs of infrared sensors plus four weight sensors for the current Plus model.
The system also connects to Android and iOS devices through the Neakasa app. Neakasa recommends fast-clumping, scoopable litter for the M1 Plus.
Best For
- Cats that prefer open-top litter boxes
- Larger cats
- Multi-cat households
- Owners who want app-based monitoring
- Owners looking for a spacious automatic design
Limitation
The M1 Plus is designed around compatible clumping litter, so it is not equally suitable for every type of litter.

Are Automatic Cat Litter Boxes Worth It?
For many cat owners, the biggest advantage is not that the litter box becomes completely maintenance-free. Instead, it changes when and how often you need to deal with waste.
Traditional litter boxes require manual scooping. Automatic models use different mechanisms—such as rotating drums or raking systems—to separate waste from clean litter and move it into a waste compartment.
That can reduce daily scooping and make litter-box maintenance more convenient.
However, an automatic litter box should not be treated as a replacement for regular cleaning. PetMD notes that even self-cleaning litter boxes still need to be cleaned and wiped down periodically.
What Should You Check Before Buying?
1. How Large Is Your Cat?
Check the manufacturer’s recommended weight range and entry dimensions.
2. Does Your Cat Prefer Open or Enclosed Spaces?
An open-top model such as the Neakasa M1 Plus or Petlibro Luma may be preferable for cats that dislike enclosed environments.
3. What Litter Does It Require?
Automatic systems do not necessarily work with every type of litter. Always check the manufacturer’s compatibility requirements.
4. How Much Space Do You Have?
Some premium automatic litter boxes are surprisingly large. Measure your intended location before ordering.
5. Do You Actually Need an App?
App monitoring can be useful, particularly in multi-cat households, but it also adds complexity and may not be necessary if your main goal is simply reducing scooping.
6. What Happens When the Power or Internet Goes Out?
Check whether the machine can continue its basic operation without an internet connection and what happens during a power interruption.
Final Verdict
The best automatic cat litter box depends on the owner’s priorities.
For advanced smart monitoring, the PETKIT Purobot Max Pro 2 is one of the strongest current options and is WIRED’s 2026 top pick.
For an established connected ecosystem, the Whisker Litter-Robot 4 remains a strong premium choice. For a simpler automatic solution, the PETKIT PuraMax 2 is worth considering.
For larger cats, the Homerunpet CS106 offers unusually generous space. For open-top smart designs, the Petlibro Luma and Neakasa M1 Plus are two notable alternatives.
The important point is that the most expensive model is not automatically the best model for every cat. The right automatic litter box is the one that matches your cat’s size, preferences, litter type, available space and the amount of automation you actually need.
