10 Best Automatic Litter Boxes 2026 in the United States

The PETLIBRO Luma Automatic Cat Litter Box combines advanced technology with user-friendly design, making it a strong choice for multi-cat households. Its standout feature is the AI waste analysis, which helps monitor your cat’s health by distinguishing between types of waste—something not common in most litter boxes. The triple safety sensors (weight, visual, and infrared) prioritize your cat’s safety by pausing cleaning cycles if a cat is near and ensuring the box is empty before starting. This is especially important with the open-top design that some cats prefer for comfort and ease of access.

In terms of odor control, the Luma uses a carbon-filtered airflow system that continuously works to keep smells down, and the sealed 2.9-gallon waste drawer can hold waste for about a week for two cats, reducing the frequency of manual emptying. It supports various litter types, including tofu, mixed, and clumping clay litters, adding to its versatility. The size is quite generous, comfortably fitting cats up to 22 pounds, and the included step helps cats enter easily.

Maintenance is relatively straightforward with replaceable filters and liners, and the sensitive weight sensor requires placing the unit on a hard, flat surface and handling it gently. The app integration offers real-time video streaming and notifications, though some features require a subscription. Auto-cleaning should be disabled for kittens or very small cats (under 2.2 lbs) for safety, so this box suits mostly adult cats. The open-top design may not be ideal if you prefer a closed litter box for extra odor containment or privacy. PETLIBRO Luma is a tech-forward, spacious, and safe automatic litter box that fits well in busy households or for cat owners seeking deeper insights into their pets’ health along with convenient cleaning.

The Litter-Robot 4 Supply Bundle by Whisker is a smart, automatic litter box designed to make cat care easier by handling waste cleaning on its own. It’s medium-sized with dimensions around 27 x 24 x 30 inches and weighs 24 pounds, so it requires a good amount of space but can serve up to four cats comfortably. The self-cleaning mechanism uses a patented sifting process that separates clumps from clean litter and stores waste in a drawer you only need to empty when full, which is very convenient and reduces daily scooping. It connects to an app that lets you monitor litter levels, waste drawer status, and even track your cat's weight, adding a modern touch for tech-friendly pet owners.

Odor control is enhanced with OdorTrap refills and carbon filters included in the bundle, which work well to minimize smells and litter tracking around the home. It works with any clumping litter, so you aren’t locked into a specific type. Cleaning the unit itself is made simpler with included liners and cleaner wipes. The noise level during operation is generally low, making it less likely to disturb cats or humans. The Litter-Robot 4 runs on a power source and should be placed on a firm, flat surface for the weight sensors to work accurately. One drawback is its size, which might be bulky for smaller living spaces, and it requires a minimum cat weight of about 3 pounds for safe use.

The product comes with a one-year warranty and is made in the USA. Some users might find the initial investment a bit high compared to manual boxes. This litter box is ideal for cat owners looking for a low-maintenance, tech-savvy solution to litter cleaning, especially those with multiple cats or busy schedules.
