10 Best Automatic Litter Boxes 2025 in the United States

The Litter-Robot 4 Supply & Accessory Bundle by Whisker is a thoughtfully designed automatic litter box that suits households with up to four cats. Its patented self-cleaning mechanism uses a sifting process to separate waste from clean litter, eliminating the need for manual scooping—just empty the waste drawer when full. This model works with any clumping litter, providing flexibility in choice. The sizable waste drawer combined with included liners means fewer trips to empty, making it convenient for busy pet owners.

Odor control is enhanced with OdorTrap packs and carbon filters included in the bundle, helping to keep unpleasant smells at bay better than traditional litter boxes. The LitterTrap mat and ramp reduce litter tracking by catching stray litter before it spreads around your home. The Litter-Robot 4 is fairly large (about 27" x 24" x 29.5"), so it requires a decent amount of floor space and is best placed on a firm, flat surface for its weight scale to work properly.

Noise level is relatively low during cleaning cycles, which benefits sensitive cats and households. Maintenance is simplified with included cleaner wipes and multiple liners, though initial setup and size may challenge some smaller living areas. The unit pairs with a smartphone app to monitor litter and waste levels, track your cat’s visits, and even weigh your cat, offering insightful features for attentive cat owners. Cats must weigh at least 3 pounds to use it safely, so it is not suitable for very small kittens. While it supports multiple cats, very large households may require additional boxes. This Litter-Robot 4 bundle delivers a high-tech, low-effort approach to litter box maintenance with solid odor control and ease of use that many cat owners will appreciate.

The Fumoi Self Cleaning Litter Box is a great choice for those with multiple cats or larger cats, as it boasts a significant 95L capacity and can accommodate cats weighing between 2.2 and 33 pounds. Its 15L waste bin is designed to handle up to 15 days of waste, making it ideal for pet owners who travel frequently. The advanced safety sensors ensure that the cleaning mechanism pauses when your cat is detected, providing peace of mind regarding your pet's safety.

The litter box supports a wide range of litter types, including mineral, hybrid, and bentonite, which makes it versatile for different preferences. Additionally, it operates quietly, helping to maintain a peaceful environment in your home. The Fumoi box also excels in odor control with its deodorizing design and detachable waterproof liner that simplifies cleaning.

The integration with the Tuya Smart APP allows for remote management, auto-cleaning, waste disposal, and health tracking, although it only supports 2.4G Wi-Fi. On the downside, the unit is rather heavy at 30.64 pounds and has relatively large dimensions of 21.6 x 19.6 x 25.8 inches, which might be cumbersome for some users. Nevertheless, the Fumoi Self Cleaning Litter Box is particularly well-suited for cat owners seeking convenience and efficiency in maintaining their pets' hygiene.

The PetSafe ScoopFree Crystal Pro Self Cleaning Litter Box offers a hands-free solution for cat owners, promising weeks of maintenance-free operation. Its automatic cleaning mechanism is a significant convenience, reducing the need for frequent scooping and refilling. The crystal litter used in this system is effective in odor control, absorbing urine and dehydrating solid waste to keep your home smelling fresh. Additionally, the low-tracking crystals help maintain a cleaner home by not sticking to your cat’s paws, minimizing the spread of litter.

The built-in health monitor and motion sensors are useful features, allowing you to track your cat's litter box usage and potentially identify health issues early on. However, it’s worth noting that this litter box is designed exclusively for use with crystal litter, which may not be preferable for all cats or owners accustomed to more traditional litters. The uncovered design might also deter some cats who prefer more privacy while using the litter box.

Although the product includes a disposable tray lined with plastic for leak protection, disposing and replacing these trays can add up in cost over time. The unit operates with minimal noise, making it suitable for indoor use without causing disturbances. The PetSafe ScoopFree Crystal Pro is a good fit for cat owners looking for a low-maintenance litter box that excels in odor control and cleanliness, though its reliance on specific litter types and the uncovered design are points to consider.
