Which Litter-Robot is best for you depends on factors such as the number of cats in your household, your budget, and how much monitoring you want.
Litter-Robot 5 is the latest design, offering a sleek and modern upgrade with features like WasteID, which distinguishes urine from faeces to enable more targeted odour control and routine monitoring.
Litter-Robot EVO is the most beginner-friendly option and the most compact model, ideal for smaller spaces and one-cat households.
With over 10,000 5-star reviews, Litter-Robot 4 is the trusted, time-tested choice—reliable and well-loved by longtime users.
Whichever model you choose, you are getting a thoughtfully designed, high-quality product that lets you stop scooping the litter box and gives your cat a fresh bed of litter for every use.
While Litter-Robot 4 is a tried-and-true option with over 10,000 5-star reviews, Litter-Robot 5 improves on the same technology and features that make Litter-Robot 4 a success with:
- WasteID technology for waste type recognition
- Slightly larger interior globe space
- Improved waste drawer distribution and size, for less frequent emptying
- Brilliant LCD display screen
- Expanded cat weight range of 1.4-13.6kg
- Accommodates up to 5 cats
Litter-Robot EVO is a more compact version of Litter-Robot 4. The EVO is a beginner-friendly option at a lower price point, 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 the LitterHopper.
