10 Best Cheap Automatic Litter Boxes 2026 in the United States

The Paruuntys Self Cleaning Litter Box offers a spacious open-top design measuring about 21.65" by 20.84", which is larger than many closed litter boxes and helps cats feel comfortable and less confined. It’s well suited for multiple cats thanks to its large 10.5-liter sealed waste bin that traps odors effectively, reducing the need for daily cleaning and making it convenient for busy owners or those away for short trips. The cleaning mechanism is smart and safe, using seven sensors to pause operation instantly if the cat is nearby, preventing accidental starts.

It also supports app control via 2.4G WiFi, allowing you to schedule cleanings and get alerts when the bin is full, which adds a modern touch for remote management. Noise-wise, it’s designed to operate quietly, so it won’t disturb your household or your cat at night. The litter box is easy to clean, featuring a leak-proof, removable waste tray and reusable liners that help reduce mess and ongoing costs. It works well with popular litter types like bentonite and mineral, but it’s not compatible with tofu-based litters, which might limit choice for some.

The unit is powered by an adapter and weighs about 23 pounds, making it stable but not very portable. Although it is somewhat larger and heavier, its features make it a strong option for cat owners seeking a user-friendly, odor-controlling, and quiet automatic litter box at an affordable price.

The Litter-Robot 4 Supply Bundle by Whisker is a medium-sized, automatic, self-cleaning litter box designed to make cat care easier. Its large dimensions (27 x 24.25 x 29.5 inches) provide ample space suitable for up to four cats, which is great for multi-cat households. The core cleaning mechanism uses a patented sifting process to separate waste from clean litter automatically, so you don’t have to scoop manually—just empty the waste drawer when it’s full. It’s compatible with any clumping litter, giving you flexibility in your choice.

The unit is WiFi-enabled and connects to a smartphone app, allowing you to monitor litter and waste levels, track your cat's activity, and even monitor their weight, which is a unique bonus not found in many cheap models. It also comes with odor control features like OdorTrap refills and carbon filters to reduce smells and litter tracking around the house. Despite its automation, it remains fairly quiet during operation, making it less disruptive in your home. The litter box is powered by electricity and needs to be placed on a firm, flat surface for best performance, as its weight sensors are less accurate on soft or uneven floors.

This model is more of an investment compared to basic cheap automatic options, but it includes useful extras like liners, wipes, and filters in the bundle to get started. Cleaning the unit itself is straightforward, though the size means it takes a bit of space. If you want a feature-rich, reliable automatic litter box with smart monitoring and don’t mind spending a bit more, this is a solid choice. For buyers prioritizing budget, simpler models might be easier on the wallet.

The Fumoi Self Cleaning Litter Box offers several notable strengths for its category. Firstly, it boasts a large 95L capacity, suitable for multiple cats or larger breeds, ensuring less frequent emptying. The cleaning mechanism is automated and controlled via a smart app, which is convenient for busy pet owners. It includes features like auto-clean, one-touch waste disposal, and health tracking, which are useful for maintaining your cat's hygiene remotely. The safety sensors are a great addition, pausing the cleaning process when your cat is detected, providing peace of mind.

Additionally, it operates quietly, a significant benefit for maintaining a peaceful home environment. The removable, washable liner simplifies the cleaning process, and the design helps prevent odors, keeping your living space fresh. It's compatible with various types of cat litter, offering flexibility in litter choice. However, there are some drawbacks to consider. The unit is relatively large and heavy, which might be cumbersome for small spaces or to move around. It also requires a 2.4G Wi-Fi connection for its smart features, which could be a limitation for some users.

Despite its strengths, the Fumoi Self Cleaning Litter Box may not be the most budget-friendly option, as there are cheaper alternatives available that still perform well. This product is best suited for cat owners with multiple or larger cats who value convenience, safety features, and smart home integration.
