FAQ

Which Litter-Robot® automatic litter box is the best?

Which Litter-Robot is best for you depends on various factors such as number of cats in your household, price point, and desired monitoring capabilities.

With over 13,000 reviews, Litter-Robot 4 is the trusted, time-tested choice—reliable and well-loved by longtime users.

Litter-Robot EVO is the best beginner-friendly option as the most compact self-cleaning litter box model, ideal for smaller spaces and 1-cat households.

Litter-Robot 5 is the latest and greatest design, offering a sleek and modern upgrade with features like WasteID, which identifies urine vs. feces to enable more targeted odor control and advanced routine monitoring.

Finally, Litter-Robot 5 Pro is packed with premium features, namely its integrated dual camera technology, for those who want the ultimate cat-monitoring experience.

No matter which Litter-Robot model you choose, you’re getting a thoughtfully designed, high-quality product that allows you to stop scooping the litter box and provides your cat with a fresh bed of litter for every use.

Litter-Robot® 5 vs Litter-Robot® 5 Pro: What is the difference?

Both of our latest-generation Litter-Robot models are ideal for multi-cat homes, kittens (at least 2 lbs), and large cats (up to 30 lbs). Each model offers best-in-class technology, including WasteID, an industry-first feature that detects whether your cat has gone #1 or #2. When you upgrade to Litter-Robot 5 Pro, you receive advanced cat identification and insights through the integrated dual camera system.

Litter-Robot® 4 vs Litter-Robot® EVO: What is the difference?

Litter-Robot EVO is a more compact version of Litter-Robot 4. Litter-Robot EVO is a beginner-friendly option at a lower price point, with fewer available app insights, and is ideal for households with one or two cats. Litter-Robot 4 is suitable for up to four cats, offers more advanced features such as litter- and waste-level sensing, and can be equipped with premium accessories like Whisker PetCam (coming soon) and LitterHopper.

What if I’m not satisfied with the model I choose?

Each of our robots comes with a 90-day in-home trial, meaning you can shop confidently, try it out, and make sure it’s the right fit for you and your cats.
