:max_bytes(150000):strip_icc()/whisker-litter-robot-4-1ffe07b807bf4f49a4d245478790e00e.jpg)
What We Like
- Intuitive interface
- Very easy to clean
- Quiet operation
- Large, inviting opening
- Useful app integration
- Thoughtful features including a night light
What We Don’t Like
- Significant space requirement
The Whisker Litter-Robot 4 isn’t just a minor update to our previous top pick, the Litter-Robot 3 Connect; it’s a complete overhaul, offering a superior automatic cat litter box experience. Through both controlled lab tests and extensive in-home trials with real cats, our testers consistently praised the Litter-Robot 4’s enhanced features, design refinements, and overall user experience.
While the Litter-Robot 4 comes with a higher price tag, Whisker justifies the premium cost with an exceptional user experience. Setup is incredibly simple as the unit arrives fully assembled. Users only need to plug it in and connect to the Whisker app using a QR code located on the device’s back.
The design of the Litter-Robot 4 immediately stands out, featuring a wide-open, circular entry perched atop a more squared base. This inviting entrance was readily accepted by cats, as confirmed by our home tester: “My three cats adapted quickly, overcoming initial hesitation about its autonomous operation!”
Noise reduction is another key improvement in the Litter-Robot 4. Testers noted its significantly quieter operation compared to the previous model. While not silent, its noise level is deemed acceptable, “Nowhere near as loud as household appliances like dishwashers,” according to one tester, “and it doesn’t bother the cats.”
The Litter-Robot 4 utilizes a fabric hammock system to hold litter. Post-bathroom use, the internal sphere rotates slowly, sifting waste through a sieve that separates solids, returning clean litter, and depositing clumps into a contained tray below.
[:max_bytes(150000):strip_icc()/sps-litter-robot-4-taylor-fox-9-665695ab98b64d1980f55abb42eb7053.jpeg)](https://www.thesprucepets.com/thmb/QzFVRm8UCFb6hU97ZAKyptNKKD0=/750×0/filters:no_upscale():max_bytes(150000):strip_icc()/sps-litter-robot-4-taylor-fox-9-665695ab98b64d1980f55abb42eb7053.jpeg)
Sensors at the entrance monitor motion and weight, ensuring cleaning cycles never start with a cat inside. This system also tracks waste amounts and can differentiate between multiple cats by weight, offering custom data. A manual cleaning mode is available for kittens under 3 pounds until they are heavy enough for sensor detection.
The Litter-Robot 4’s control panel, while initially appearing complex due to numerous settings, is ultimately intuitive with large, colorful buttons. One tester initially made a mistake by emptying all litter instead of initiating a clean cycle, highlighting a slight learning curve.
Cleaning the Litter-Robot 4 is remarkably easy. Reservoir bags are tall, simplifying removal and tying off, even when full.
While it may seem unusual to describe a litter box as enjoyable, the Litter-Robot 4’s comprehensive and thoughtful design, including a built-in night light, consistently impressed our testers. It also noticeably freed up time. “Not having to daily clean makes travel easier,” one tester mentioned, adding that their cat sitter appreciated not having to handle litter during a week-long trip, allowing more playtime with the cats.
One minor drawback noted was a potential increase in odor. While the Litter-Robot 4 has odor-reducing features, separating waste into a tray can diminish the odor-absorbing qualities of the litter itself. This is a common issue with automatic litter boxes that isolate waste from the main litter supply.

Pet Zone Pet Zone Smart Scoop
What We Like
- Quiet cleaning cycle
- Odor-absorbing filter included
- Functional, straightforward features
- Easy bag installation
What We Don’t Like
- No storage for the included scoop
- Small waste particles can bypass the rake
- Shallow waste reservoir
The Pet Zone Smart Scoop Automatic Litter Box is designed to detect when your cat uses it and initiates a cleaning cycle 30 minutes later. It employs a rake mechanism to scoop clumps into a waste reservoir. As one tester summarized, “It lacks fancy features but effectively gets the job done.”
[:max_bytes(150000):strip_icc()/PEO-pet-zone-smart-scoop-automatic-litterbox-vicky-wasik-photo-09.jpg-2e50b0c901f94a069f3d0fdc74be149c.jpg)](https://www.thesprucepets.com/thmb/eXebRjtg8jCtWHFdA6hVmwBl0FA=/750×0/filters:no_upscale():max_bytes(150000):strip_icc()/PEO-pet-zone-smart-scoop-automatic-litterbox-vicky-wasik-photo-09.jpg-2e50b0c901f94a069f3d0fdc74be149c.jpg)
The Pet Zone stands out for its quiet operation. The slow-moving rake effectively captures most waste, and its design prevents clogs (a cleaning tool is also provided).
The unit includes six starter plastic bags that are easy to install and remove when full. A carbon zeolite filter is also included, fitting under the waste reservoir lid for odor control.
While initial concerns arose about the plastic construction’s durability, our test unit remained functional after months of use.
“It’s not the most stylish, but it’s practical and affordable,” noted our tester.
A minor downside is the shallow litter box depth, which might not provide enough litter for cats that prefer to dig and bury. A dedicated storage spot for the provided scoop would also be beneficial.
Despite its basic feature set, the Pet Zone Smart Scoop performs well, including its odor filter. Our tester reported no noticeable odors throughout weeks of testing.

Litter-Robot 3 Connect Cat Litter Box
What We Like
- Consistently high performance in automatic litter box testing
- Excellent customer support
What We Don’t Like
- Larger and noisier than the Litter-Robot 4
While the Litter-Robot 4 is a significant upgrade, the Litter-Robot 3 Connect remains a quality automatic cat litter box, especially considering its reduced price. We’ve conducted extensive long-term testing with multiple Litter-Robot 3 Connect units over several years, affirming its reliability.
During our tests, one unit experienced a “bonnet” error, falsely indicating an open top panel. Litter-Robot customer service promptly provided troubleshooting and offered a replacement, showcasing their responsiveness.
In a direct comparison with the Leo’s Loo Too in a multi-cat household, testers slightly preferred the Leo’s Loo Too, and cats also showed a preference for it over the Litter-Robot 3.
Overall, the Litter-Robot 3 is larger, less aesthetically refined, and slightly louder than the Litter-Robot 4. However, its lower price point may make it an attractive option for budget-conscious buyers seeking a reliable automatic cat litter box.

Neakasa M1 Open-Top Self-Cleaning Cat Litter Box
What We Like
- Open-top design with safety guard
- Suitable for cats up to 33 pounds
- App connectivity for data and control
- Quiet operation, similar to a refrigerator
What We Don’t Like
- High entry point
In a market dominated by enclosed automatic litter boxes, the Neakasa M1 offers a refreshing open-top design. Despite appearing bulky, its footprint is average. We tested this automatic cat litter box with three cats, including a Maine Coon, and found it suitable for larger breeds.
Assembly was straightforward, requiring only feet and tray attachment. The app setup, involving Bluetooth and Wi-Fi pairing, took a bit longer but was not complex.
Cat acclimation took some time, likely due to the high 13.77-inch entry. This elevated open-top design, accommodating larger cats up to 33 pounds, is ideal for bigger breeds but might be less accessible for smaller or senior cats. The litter area, however, seemed somewhat small for a large Maine Coon, suggesting it’s best suited for a single large cat household.

Tracking was comparable to standard litter boxes, even with the included mat, likely due to cats jumping out from the high entry.
Cleaning was easy, involving a simple wipe-down. Deeper cleaning of crevices would be challenging as the unit doesn’t fully disassemble. The lined waste receptacle simplified waste disposal. Odor control was better than standard boxes but not entirely sealed due to the open design.

:max_bytes(150000):strip_icc()/CasaLeoLeosLooTooBoxforCats-e2088b50e8b3482889d7d55d9a2b804d.jpg)
What We Like
- Alexa and Google voice control
- Large waste reservoir capacity
- Very quiet cleaning cycle
- Variety of color options
What We Don’t Like
- Slightly more challenging to clean compared to top picks
The Casa Leo Leo’s Loo Too follows a classic automatic litter box design, using a rotating barrel to sift clumps into a lower reservoir. Cats readily adapted to the Leo’s Loo Too, partly due to its quiet cleaning cycle.
While the app is less visually appealing than the Whisker app, the Casa Leo excels in smart home integration, compatible with both Amazon Alexa and Google Home for voice control. App setup is also user-friendly.
Ideal for hygiene-conscious owners, the Casa Leo features UV sterilization in the waste drawer to eliminate bacteria and viruses. While waste is bagged, this feature adds an extra layer of sanitation.
Odor control is excellent, even with the large waste drawer allowing for less frequent emptying (weekly or longer for single cats). However, multi-cat households may require bag changes every 48 hours. Customizable cleaning settings allow for post-use cleaning cycles.
Available in four colors, the Casa Leo Leo’s Loo Too includes a 90-day trial.

Best with Crystal Litter
PetSafe ScoopFree Complete Plus Litterbox
What We Like
- Excellent odor control
- App integration for remote control and usage tracking
- Compact size, similar to standard litter boxes
What We Don’t Like
- Crystal litter not universally accepted by cats
- Tray replacement or reservoir emptying is cumbersome
We previously reviewed an earlier PetSafe ScoopFree model with similar positive findings. The primary consideration is crystal litter acceptance. Crystal litter excels at odor absorption and is dust-free but may require cat acclimation and is generally more expensive.
If your cat uses crystal litter, the PetSafe ScoopFree Complete Plus is a top choice. It automatically rakes waste 20 minutes post-use, moving solids to a compartment, while crystal litter absorbs urine and odors.
Monthly tray replacement (for single-cat homes) is simple: slide out the tray, lid it, and discard. The quiet automatic raking system effectively removes solid waste with minimal visibility or handling.
However, this entails ongoing crystal litter tray purchases, increasing long-term costs despite the ScoopFree’s lower initial price. While reservoir emptying without full tray replacement is possible, it’s awkward, requiring lifting the device’s upper section.
In-home testing confirmed effective self-cleaning and odor control. Unlike larger models like the Litter-Robot 4, the PetSafe ScoopFree is space-efficient, ideal for apartments. A “smart” Wi-Fi-enabled app version with a hood is also available.

Best App Controls
Catlink Self-Cleaning Litter Box- Scooper Luxury Pro-X
What We Like
- Easy app setup with comprehensive health monitoring
- Intuitive litter box and app design
- Integrated safety sensors
- Two-week waste reservoir capacity
- Whisper-quiet operation
- Includes two sifting filters for different litters
What We Don’t Like
- Entry ramp sold separately
- High entry point
Testers praised the Catlink Self-Cleaning Litter Box for its easy setup and app integration, which features extensive data beyond standard usage stats, including waste bin fullness, humidity, temperature, and litter levels. The app also integrates with Alexa and Google Home.
Despite its larger footprint, its odor control, utilizing a carbon filter, UV sterilization, and a purifier, is exceptional, allowing placement in odor-sensitive areas. Operation is whisper-quiet at 30 decibels, suitable for nervous cats.
Standout features include a control panel lock, a large two-week waste bin, and dual safety sensors. Two sifter grates accommodate various litter types. However, an anti-tracking ramp is sold separately, which would be beneficial given the high entry point, especially for smaller or older cats.

Best Tracking Prevention
PetSnowy SNOW+ Self-Cleaning Litter Box
:strip_icc()/petsnowy–snow–self-cleaning-litter-box-455cf7c26d5c415c82d8b4e8514c7aa0.jpg)
What We Like
- Top door for easy litter refills
- Pre-litter area with mat and staggered entry to minimize tracking
- Suitable for multi-cat households
- Self-sealing waste bags
- Triple odor control, no replacements needed
What We Don’t Like
- Larger and heavier than other models
- Unreliable app connection
The PetSnowy SNOW+ Self-Cleaning Litter Box was tested in a four-cat household using clumping clay litter. Cats enter through a side oval window into a pre-litter area with a removable mat. This, combined with the stepped entry, effectively traps litter from paws before cats exit.
[:max_bytes(150000):strip_icc()/sps-litter-boxes-apr-24-test-petsnowy-snow-self-cleaning-megan-wood-15-282ddf593e0047bdb457041fb50ce9ee.jpeg)](https://www.thesprucepets.com/thmb/gycf0IODpCx9PXiDGbVRmUclYjc=/750×0/filters:no_upscale():max_bytes(150000):strip_icc()/sps-litter-boxes-apr-24-test-petsnowy-snow-self-cleaning-megan-wood-15-282ddf593e0047bdb457041fb50ce9ee.jpeg)
Despite four cats sharing one box, odor control remained excellent, even with the lid removed. Cats new to automatic litter boxes adapted after removing the top section, although this triggered an app error without disabling functionality.
Self-sealing waste bags in the waste tray are a game-changer for bag replacement, odor containment, spillage prevention, and hygiene. Disassembly facilitates thorough cleaning.
App connectivity was unreliable, and historical usage data was unavailable, limiting data access to the current day.

Best Litter Box Accessory
Petivity Litter Box Monitor
What We Like
- Tracks litter box use and alerts for changes
- Monitors up to five cats per device
- Data presented in charts and reports
- Battery or AC power options
What We Don’t Like
- Requires a device per litter box
- Litter box size limitations
For those hesitant to switch to an automatic litter box or with picky cats, the Petivity Smart Litter Box Monitoring System is a valuable accessory. Tested in a two-senior-cat household, it provided useful insights into cat health through weight and bathroom habit tracking.
Setup is straightforward, involving app-based cat health information input. Post-setup interaction is primarily app-based.
The device functions like a scale, placed under the litter box, powered by batteries or AC. It tracks weight, frequency, duration of litter box use, and elimination type. Data is presented in charts and reports, printable for records or vet visits.
Each Petivity monitor supports up to five cats. Multiple litter boxes require separate devices for complete data. It accommodates litter boxes up to 21×16 inches and is incompatible with automatic models.

Final Verdict
For a hands-off litter cleaning experience, the Whisker Litter-Robot 4 is our top automatic litter box recommendation. It significantly improves upon earlier Litter-Robot models, offering a user-friendly interface and quiet operation. For a more budget-friendly automatic option, the Pet Zone Smart Scoop effectively manages odors and clumps with its reliable rake system.
How We Tested Automatic Litter Boxes
We’ve evaluated 23 automatic and self-cleaning litter boxes over a year, in our New York Lab and in real homes. Lab tests involved side-by-side comparisons to assess convenience. Home testing included further comparisons and long-term trials, with cats often having access to multiple automatic litter box models to express their preferences.
Each automatic litter box was assessed on:
- Ease of Setup: Time taken to set up and operate, noting clarity of instructions and app usability.
- Ease of Use: Evaluation of interface intuitiveness and manual cleaning cycle processes.
- Performance: Simulated solid waste tests with modeling compound and vinegar-scented water for odor control, followed by real-world pet waste observations.
- Cleaning and Odor Control: Post-multiple cleaning cycles, units were emptied, cleaned, and assessed for odor elimination.
- Value: Testers rated overall impressions and perceived value before and after price disclosure.
Most automatic litter boxes were purchased for testing, with manufacturer-provided review models noted.

The Competition
Several other popular automatic litter boxes were considered in our evaluation.
What to Consider When Shopping for an Automatic Litter Box
Litter Compatibility
Most recommended automatic litter boxes are compatible with various litter types, with exceptions like wood-based pellets. Clumping clay litter is generally ideal for automatic systems that filter hard clumps. Cylindrical designs can increase tracking, potentially favoring pellet or coarser litters. Crystal litter is a dust-free, odor-absorbent silica option, but cat acclimation may be needed.
Size
Automatic litter boxes generally have a larger footprint. Cylinder models are tall and visually imposing, while rake-based models often have a lower profile. Measuring intended space is essential.
[:max_bytes(150000):strip_icc()/sps-automatic-cat-litter-box-test-robot-4-taylor-fox-01-dc6e920b1de145329d89fe4d5d30f778.jpeg)](https://www.thesprucepets.com/thmb/zBvdHIzJJm6G8NVGdHgibL0hbjI=/750×0/filters:no_upscale():max_bytes(150000):strip_icc()/sps-automatic-cat-litter-box-test-robot-4-taylor-fox-01-dc6e920b1de145329d89fe4d5d30f778.jpeg)
Additional Costs
Beyond the initial cost ($150-$650), consider recurring expenses like proprietary bags, filters, or deodorant sprays. While workarounds exist, manufacturer-designed bags often optimize performance.
FAQ
- How do you get cats to use an automatic litter box? Introduce the new litter box gradually. Place it near the existing one, unplugged, filled with litter. Once accepted, run cleaning cycles a few times daily, encouraging cat interaction with praise and treats. Catnip or training litter can aid reluctant cats. Remove the old litter box after a week of consistent use.
- How often should automatic litter boxes be cleaned? Deep clean monthly, or more often for multiple cats, with full litter replacement. Specific brand guidelines may vary.
- Do automatic litter boxes smell? They reduce odor by prompt waste removal, but complete odor elimination is unrealistic. Odor intensity depends on cat diet and health. Regular cleaning and appropriate cat load management minimize smells.
