Editor's note

Open-top design vs an enclosed flagship. The Neakasa M1 has an open top that cats enter easily at a lower price, while the Litter-Robot 4 is the acclaimed king for its enclosed design, cat ID, and quietness. Choose Neakasa for easy entry and price, Litter-Robot 4 for features and reliability.
