The self-cleaning mechanism uses multiple sensors to ensure safe operation, stopping the rotation when a cat is inside, which adds a good layer of safety. You can control and monitor the litter box through a smartphone app, allowing you to track usage and get alerts when maintenance is needed—this is handy if you want remote management and health insights for your cats.
