An automatic litter box sifts the waste out of the litter after every visit and drops it into a sealed drawer, so you empty a bin about once a week instead of scooping every day. The app-connected models also log each visit, track your cat’s weight and tell you when the drawer is full. For most homes, the best automatic litter box is the Litter-Robot 4: it has a long track record, handles up to four cats and stops the moment a cat steps in.
More cats, a very large cat, a small apartment or a tighter budget change the answer, so the options below cover each of those cases.
Quick Recommendations
- Litter-Robot 4 — Best overall. A proven self-cleaning globe for up to four cats, with litter and waste levels in the app.
- PETLIBRO Luma — Best for multiple cats. A camera recognizes up to 10 cats and logs each visit to the right one.
- PETKIT Purobot Max 3 — Best value. A large drum, a low entrance and up to 15 days between bin changes for one cat.
- Neakasa M1 Plus — Best for large cats. An open-top design for cats up to about 33 lbs.

None of these litter boxes work with Apple Home, Google Home or Matter, and none has an official Alexa skill, so you’ll use each brand’s own app for alerts and settings. The Litter-Robots are the only ones with an official Home Assistant integration, and the PETKIT, Neakasa and PetSafe connect only to 2.4 GHz Wi-Fi.
How Self-Cleaning Litter Boxes Work
The best self cleaning litter box for your home depends partly on its design. There are three main ones, and they decide what litter you can use and how much space you need.
Rotating globes and drums (Litter-Robot, PETKIT, PETLIBRO) turn slowly after your cat leaves. A screen holds back the clean litter while the clumps fall into a sealed drawer. They need clumping litter and take up more floor space than a regular box.
Open-top sifters (Neakasa) rotate a shallow, uncovered tray instead of a closed globe. Cats that won’t walk into a covered box often accept them, and big cats have more room to turn around.
Rake systems (PetSafe ScoopFree) use non-clumping crystal litter in a disposable tray. A rake pushes the waste into a covered trap, and you replace the whole tray when it’s used up.
Safety is the most important thing to check. Every option here waits until your cat has left before it cleans, the rotating models stop when a cat steps back in, and each brand sets a minimum weight (usually around 3 lbs) for automatic mode, so kittens should use manual cleaning until they’re heavy enough. Avoid cheap drum designs whose entrance closes while the drum turns: the PETKIT and Neakasa models keep the opening clear during the whole cycle. If you’re also automating mealtimes, our guide to the best automatic cat feeders covers the other half of the setup.
The Best Automatic Litter Boxes in 2026
Litter-Robot 4 — Best Overall
The Litter-Robot 4 is the best choice for most homes: it cleans reliably after every visit, it works with almost any clumping litter and its app shows exactly how full the drawer and the globe are.
Best for: Homes with one to four cats that want a dependable self-cleaning box with detailed health data.
What stands out in real use
After your cat leaves, the globe waits a few minutes and then turns to sift the clumps into the drawer underneath. A laser curtain sensor and a scale in the base detect when a cat steps in, so the cycle stops and waits. The scale also weighs your cat on every visit, which helps you notice weight loss or more frequent visits early, and the app shows the litter and waste levels in real time. The Whisker app’s standard insights are free, and the optional Whisker+ membership ($7.99 a month or $79.90 a year) adds longer history and more detailed tracking. Whisker released the Litter-Robot 5 ($799) and 5 Pro ($899) in October 2025, which add urine and stool detection and, on the Pro, cameras. They’re sold by Whisker rather than on Amazon, and the Litter-Robot 4 still covers what most owners need for less. If you’re unsure about the price, our guide to whether the Litter-Robot is worth it explains what it costs to run.
Key specs
- Rotating globe with a sealed waste drawer underneath
- Curtain sensor and scale stop the cycle when a cat enters
- Up to 4 cats, each at least 3 lbs
- 27 x 24.25 x 29.5 inches, 24 lbs
- 1-year WhiskerCare warranty, 90-day returns
Pros
- Long track record (the first Litter-Robot came out in 2000)
- Shows litter and waste levels in the app
- Weighs each cat on every visit
- Works with Home Assistant through an official integration
Cons
- Most expensive option on Amazon here
- Takes up more space than a regular box
- Weight readings are less accurate on carpet
- No Alexa, Google Home or Apple Home support
Installation and compatibility notes
Place it on a firm, level floor and keep it away from walls and corners, as Whisker requires. Fill the globe with clumping litter to the fill line and connect it to the Whisker app. If you buy it outside Whisker’s own store, activate the WhiskerCare warranty in the app before you need it. Home Assistant users can add it with the official Whisker integration, and our comparison of Home Assistant and HomeKit explains which platform fits devices like this one.
Price: ~$699
PETLIBRO Luma — Best for Multiple Cats
The Luma is the best automatic litter box for multiple cats because its camera tells your cats apart instead of guessing from their weight.
Best for: Homes with several cats, especially cats of a similar size, where you want to know who used the box and when.
What stands out in real use
Most self-cleaning boxes identify cats by weight, which gets confused when two cats weigh about the same. The Luma’s 1080p camera recognizes up to 10 cats from different angles and logs each visit to the right profile, and the app alerts you when a cat hasn’t used the box for 24 hours. Weight, camera and infrared sensors all have to confirm the box is empty before it cleans. A fan pushes air through a carbon filter to control odors, and the 11-liter drawer holds about a week of waste for two cats. Live view, visit logs and alerts are free. AI waste analysis, recordings and playback need a Video Cloud AI plan, which starts at $95.99 a year.
Key specs
- Camera recognition for up to 10 cats
- Weight, camera and infrared safety sensors
- 11-liter drawer, about 7 days of waste for 2 cats
- Cats from 2.2 to 22 lbs
- Wi-Fi, 2.4 and 5 GHz, 24-month warranty
Pros
- Identifies cats of similar weight correctly
- Free live view and inactivity alerts
- Built-in fan and carbon filter for odor
- Works on 5 GHz Wi-Fi as well as 2.4 GHz
Cons
- Waste analysis and recordings need a subscription
- Hard floors only, not carpet
- Clumping litter only, no crystal or pine
- No Alexa, Google Home or Apple Home support
Installation and compatibility notes
Set it on a hard, level floor with about 4 inches of space around it. Petlibro suggests placing it next to your current box for the first days, with automatic cleaning off and the fan on low, so your cats get used to it. Pet recognition and cleaning keep working when your Wi-Fi drops. If you’d also like to watch your cats in the rest of the room, a dedicated pet camera covers more than the camera on a litter box.
Price: ~$600
PETKIT Purobot Max 3 — Best Value
The Purobot Max 3 gives you a large drum, a sealed side bin and multi-cat tracking for much less than a Litter-Robot.
Best for: Owners who want a capable self-cleaning box for one to several average-size cats without spending $600 or more.
What stands out in real use
PETKIT released the Max 3 in August 2026 as the follow-up to the PuraMax 2, with a wider, lower entrance (about 8 inches off the floor) that older and short-legged cats can step into easily. The drum’s gear is designed with a gap, so the entrance stays open even if the power or sensors fail, and 12 sensors stop the drum when a cat comes close. After a visit, an optional setting covers the waste with litter before it rotates the clump into the 7-liter side bin, which lasts up to 15 days for one cat. The app tracks each cat’s visits and weight separately, and the buttons on top handle cleaning, leveling and maintenance without your phone.
Key specs
- 76-liter drum, entrance about 10.5 x 10.7 inches
- 7-liter sealed waste bin, up to 15 days for 1 cat
- 12 sensors and an entrance that always stays open
- Cats from 3.3 to 22 lbs, 6 months and older
- Wi-Fi, 2.4 GHz only
Pros
- Much lower price than the Litter-Robots
- Low entrance for older cats
- Physical design keeps the entrance open during a cycle
- Works with clay, tofu and mixed clumping litters
Cons
- Tells cats apart by weight only
- Not suitable for carpet
- Smaller bin than the Luma or Neakasa
- No Alexa, Google Home or Apple Home support
Installation and compatibility notes
Place it on a flat, hard floor and keep the entrance clear. Connect it to the PETKIT app on a 2.4 GHz network. PETKIT includes two sifting screens, one for large-grain litter and one for finer litter, so use the one that matches your cat’s litter. PETKIT’s Alexa skill covers its feeders, not this litter box.
Price: ~$430
Neakasa M1 Plus — Best for Large Cats
The M1 Plus is the best choice for large cats, and for cats that refuse covered boxes, because the litter area is fully open on top.
Best for: Maine Coons, Ragdolls and other big cats, or cats that won’t use an enclosed box.
What stands out in real use
Instead of a closed globe, the M1 Plus has a wide, uncovered tray that rotates to sift out the clumps, so a large cat can turn around and dig like it would in a regular box. Neakasa rates it for cats up to about 33 lbs and up to three cats. Six sets of rotating infrared sensors watch the tray from several angles and pause the cycle when a cat comes near, and a Kitten Mode switches to manual cleaning for very small cats. The waste drops into a bag in an 11.2-liter bin, which you pull, tie and throw away every 7 to 14 days.
Key specs
- Open-top rotating tray
- Cats up to about 33 lbs, up to 3 cats
- 6 sets of rotating infrared sensors, Kitten Mode
- 11.2-liter waste bin with pull-and-tie bags
- Wi-Fi, 2.4 GHz only, 2-year protection plan
Pros
- Most room of any option here
- Open design suits cats that dislike covered boxes
- Bags make emptying the bin quick
- Two-year protection plan
Cons
- Open top lets more litter scatter
- Large footprint
- Only identifies up to 3 cats
- No Alexa, Google Home or Apple Home support
Installation and compatibility notes
The M1 Plus needs about 3.4 square feet of floor space, so measure the spot first. Use clumping litter and put a litter mat in front of it, since an open top lets cats kick more litter out. Connect it to the Neakasa app on 2.4 GHz Wi-Fi.
Price: ~$450
Litter-Robot EVO — Best for Small Spaces
The EVO is the smallest Litter-Robot, made for apartments and homes with one or two cats.
Best for: Small apartments, bathrooms and tight corners, or first-time owners of an automatic litter box.
What stands out in real use
Whisker launched the EVO in October 2025 as a more compact Litter-Robot: about 20.6 by 24.3 inches of floor space and 27.6 inches tall. It uses the same sifting globe as the bigger models and weighs each cat to tell up to two of them apart in the app. Unlike the Litter-Robot 4, it can sit on carpet. However, it doesn’t have the Litter-Robot 4’s litter level sensing or support for the LitterHopper refill accessory, and its drawer needs emptying a little more often. You can delay the cleaning cycle up to 30 minutes for nervous cats.
Key specs
- Compact sifting globe, 20.6 x 24.3 x 27.6 inches
- Up to 2 cats, each at least 3 lbs
- Weight-based cat identification in the Whisker app
- Works on any floor, including carpet
- Clumping litter only
Pros
- Smallest footprint of the globe designs here
- Can sit on carpet
- Same app and Home Assistant support as the Litter-Robot 4
- $100 less than the Litter-Robot 4
Cons
- Only for one or two cats
- Doesn’t show the litter level
- Smaller drawer than the Litter-Robot 4
- No Alexa, Google Home or Apple Home support
Installation and compatibility notes
Set it up like the Litter-Robot 4: fill it with clumping litter, connect the Whisker app and set the cycle delay that suits your cat. If you have more than two cats or might add one, choose the Litter-Robot 4 instead.
Price: ~$599
PetSafe ScoopFree Crystal Smart — Best Budget Option
The ScoopFree Crystal Smart is the cheapest way to get a self-cleaning box with an app, as long as you’re fine with buying replacement trays.
Best for: Single-cat homes that want hands-free cleaning and visit alerts for about $227.
What stands out in real use
Instead of a rotating drum, a rake sweeps the waste into a covered compartment after each visit. The crystal litter absorbs urine and dries out stool, and the disposable tray lasts up to 30 days with one cat (multi-cat homes change it more often). The My PetSafe app shows a log of visits and reminds you when it’s time to change or reorder trays. However, the app can’t tell which cat used the box, and the trays are an ongoing cost: a 3-pack costs about $73 on Amazon, so plan for roughly $25 a month with one cat. You can switch to PetSafe’s reusable tray to lower that.
Key specs
- Rake system with disposable crystal litter trays
- Up to 30 days per tray for 1 cat
- Visit log and tray alerts in the My PetSafe app
- Front-entry hood, 1 tray included
- Wi-Fi, 2.4 GHz only
Pros
- Lowest price here
- Crystal litter keeps dust and odor low
- You replace the whole tray without touching the waste
- Sold and shipped by Amazon
Cons
- Trays add a monthly cost
- Can’t tell cats apart
- Less suited to multi-cat homes
- No Alexa, Google Home or Apple Home support
Installation and compatibility notes
Use only crystal litter in this box, since clumping clay jams the rake. Plug it in, connect the My PetSafe app on 2.4 GHz Wi-Fi and set the tray reminder. If your cat is used to clay litter, mix a little of the old litter on top for the first week.
Price: ~$227
How to Choose an Automatic Litter Box
Check your cat’s size and age. Each box has a weight range for automatic cleaning, usually from about 3 lbs up to 22 lbs, with the Litter-Robot 4 (25 lbs) and the Neakasa M1 Plus (about 33 lbs) going higher. Kittens below the minimum should use manual mode until they grow.
Count your cats, then add a box. The Merck Veterinary Manual recommends at least one more litter box than the number of cats, and one self-cleaning box doesn’t change that. In a multi-cat home, an automatic box keeps the busiest box clean, and camera recognition (the Luma) tracks each cat more reliably than weight alone.
Compare running costs. The globe and drum designs use regular clumping litter plus liners, bags or filters. The ScoopFree uses disposable trays, so it costs less upfront and more every month.
Plan the spot. Most of these need a hard, level floor and some space around them for the sensors to work. Measure before you buy, especially for the Litter-Robot 4 and the Neakasa.
Decide on subscriptions before you buy. Cleaning, alerts and basic logs are free on every option here. Whisker and Petlibro charge for longer history, recordings and AI analysis.
Give your cat time. Keep the old box nearby for the first days and turn off automatic cleaning until your cat uses the new one without hesitation. If you’re adding other pet devices, our guide to the best automatic cat doors covers another task you can automate.
Conclusion
The Litter-Robot 4 is the best automatic litter box for most homes: it cleans reliably, handles up to four cats and shows the litter and waste levels in its app. The PETLIBRO Luma is the best choice for several cats of a similar size, and the PETKIT Purobot Max 3 gives you most of the same convenience for much less. Large cats are more comfortable in the open-top Neakasa M1 Plus, the Litter-Robot EVO fits small spaces, and the PetSafe ScoopFree Crystal Smart is the lowest-cost way to stop scooping.
What is the best automatic litter box?
The Litter-Robot 4 is the best automatic litter box for most homes. It sifts the litter after every visit, stops when a cat steps in, handles up to four cats and shows the litter and waste levels in the Whisker app.
What is the best automatic litter box for multiple cats?
The PETLIBRO Luma is the best choice for multiple cats because its camera recognizes up to 10 cats and logs each visit to the right one, even when cats weigh about the same. Vets still recommend one more litter box than the number of cats.
Are self-cleaning litter boxes safe for cats?
The models in this guide pause when their sensors detect a cat, and each sets a minimum weight (usually around 3 lbs) for automatic cleaning. Kittens below that weight should use manual mode, and it’s best to avoid cheap drum designs whose entrance closes during a cycle.
Do self-cleaning litter boxes need a subscription?
No. Cleaning, alerts and basic visit logs work without one on every box in this guide. Whisker+ adds longer history and detailed tracking, and Petlibro’s Video Cloud AI plan adds recordings and AI waste analysis.
What litter do automatic litter boxes use?
The Litter-Robot, PETKIT, PETLIBRO and Neakasa models use clumping litter, since they sift out the clumps. The PetSafe ScoopFree Crystal Smart uses non-clumping crystal litter in disposable or reusable trays.
Do automatic litter boxes work with Alexa or Apple Home?
None of the boxes in this guide work with Apple Home, Google Home or Matter, and none has an official Alexa skill. The Litter-Robots can be added to Home Assistant through its official Whisker integration.
