10 Best Robots For Litter 2025 in the United States

The Neakasa M1 Open-Top Self Cleaning Cat Litter Box offers a spacious and easy-to-access design, which is beneficial for cats of all sizes. Its open-top feature allows for natural behaviors and easy adaptation, making it a comfortable choice for pets.

The large waste and litter capacities mean less frequent maintenance, ideal for busy owners or those who travel often. This model also supports multi-cat households, accommodating cats from 2.2 to 33 lbs, including a special Kitten Mode for smaller cats.

Safety is prioritized with multiple infrared and weight sensors, pausing cleaning operations when a cat is detected inside the box. The accompanying Neakasa app provides remote control and monitoring capabilities, enhancing convenience for pet owners.

The PETKIT PuraMax 2 is a large, automatic self-cleaning cat litter box designed for multi-cat households and cats weighing between 3.3 and 22 pounds. Its generous interior space and low-entry design make it accessible for older or less mobile cats. The self-cleaning mechanism is versatile with several modes—auto, manual, timer, and empty—controllable via a smartphone app, which also tracks your cat’s weight and bathroom habits, offering useful health insights. The unit features a 7-liter waste drawer that can hold about 15 days’ worth of waste, reducing frequent maintenance. Odor control is strong, thanks to a sealed waste bin and a special odor eliminator included in the bundle, helping keep the area fresh.

Safety is well-thought-out with infrared and weight sensors that pause cleaning when your cat is near, and an anti-pinch design to prevent accidents. It supports all clumping litters but isn’t compatible with some smart sprays. The device should be placed on a flat surface, not on carpets, to avoid sensor issues. At 22 pounds, the unit is relatively heavy and sizable, which might be a consideration if you need to move it often. While it offers quiet operation, some users might notice noise during cleaning cycles. The PETKIT PuraMax 2 is a strong choice for busy cat owners looking to simplify litter box maintenance with smart features, good odor control, and safety, especially fit for multiple cats or larger cats, though it does require some setup and app use.

The Litter-Robot 4 Supply & Accessory Bundle by Whisker is a medium-sized, automatic self-cleaning litter box designed for households with up to four cats. Its dimensions (27" x 24.25" x 29.5") and 24-pound weight make it a substantial unit that requires sufficient space. It offers a generous waste drawer capacity, reducing the frequency of emptying. The patented sifting mechanism automatically separates waste from clean litter, eliminating the need for manual scooping. This model is compatible with any clumping litter, allowing users to choose their preferred type.

Odor control is effectively managed through OdorTrap Packs and carbon filters, which reduce smells more efficiently than traditional boxes. The bundle also includes a LitterTrap mat and ramp to minimize litter tracking around the home. Through the Whisker app, users can monitor waste levels, litter amount, and track their cat’s weight, providing a useful tool for pet health. The unit is designed for cats above 3 lbs and performs best on firm surfaces to ensure accurate weighing. Setup and maintenance are straightforward, aided by included liners, wipes, and filters.

While the size may not suit very small spaces and the waste drawer still requires regular emptying despite the self-cleaning feature, the included accessories and warranty contribute to the overall value. Although the initial cost might be high for some, this product is an excellent option for those looking to eliminate daily scooping and effectively control odors and litter tracking, especially in multi-cat households.
