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 & 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 Litter-Robot 4 Supply & Accessory Bundle is a smart, automatic litter box designed to make cat care easier, especially for owners of multiple cats. Its size is fairly large (27 x 24.25 x 29.5 inches), so it requires a dedicated space and a firm surface for proper functioning. It can handle up to four cats weighing at least 3 pounds each, making it suitable for most households with several pets. The standout feature is its patented self-cleaning mechanism that sifts waste into a drawer you only need to empty when full—this means no daily scooping.

The unit connects to a phone app, letting you monitor litter levels, waste drawer status, and even track your cat’s weight, which is a nice bonus for health-conscious owners. Odor control is addressed with included OdorTrap packs and carbon filters, plus a mat and ramp to reduce litter tracking around the house. It works with any clumping litter, offering flexibility in what you use. Cleaning is simplified further with waste drawer liners and included wipes. Noise level is generally low, though some cats may notice the cleaning cycle. Power comes from a standard electrical source, so it needs to be near an outlet.

Its large footprint and weight (24 pounds) might be challenging for small spaces or frequent moves. Also, while the initial bundle includes many useful accessories, replacement filters and liners will be an ongoing cost. This product is a strong option for cat owners looking to reduce daily litter chores, manage odors better, and keep an eye on their pets’ health with smart features.
