10 Best Automatic Litter Boxes 2025 in the United States

The Neakasa M1 Open-Top Self Cleaning Cat Litter Box is designed for convenience and comfort, making it a great choice for busy cat owners or those with multiple cats. Its open-top design is particularly appealing, as it allows for easy access and encourages natural behavior, which is important for cat comfort. With a large waste capacity of 11.23 liters and litter capacity of 7.17 liters, this litter box can operate for up to 14 days without needing a refill, perfect for short trips or hectic schedules.

One of the standout features is its self-cleaning mechanism, which alleviates the need for manual scooping and helps keep the litter box hygienic.

The Litter-Robot 4 Supply Bundle by Whisker is a medium-sized automatic litter box designed for up to four cats, each weighing at least 3 pounds. It measures about 27 x 24 x 29.5 inches, making it somewhat large but suitable for multi-cat households. Its standout feature is the patented self-cleaning system that sifts waste from clean litter automatically, so manual scooping isn’t needed. You simply empty the waste drawer when full.

The unit connects to WiFi and pairs with an app, allowing you to monitor litter levels, waste drawer status, and even track your cat’s weight, which is unique for this type of product. It works with any clumping litter, providing flexibility in choice. The included OdorTrap refills and carbon filters help reduce unpleasant smells effectively, and the cleaning wipes make maintenance easier. Noise is generally low, but some cats might need time to adjust to the automatic cycling sound.

The Litter-Robot 4 requires a firm, flat surface for best accuracy in its weight and activity sensors, which might limit placement options. It runs on a power cord, so it needs an outlet nearby. The bundle comes with a one-year warranty and is made in the USA, which may appeal to buyers valuing domestic quality. Considering its size and price, especially for smaller spaces or budgets, the product offers strong features and reliability, making it an efficient, hands-off litter solution with smart monitoring capabilities.

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.
