The Litter Robot 4 uses a simple yet effective mechanism to clean itself after each use. Here’s how it works:
 

Detection: After your cat enters the litter box, it triggers a sensor that detects the presence of the cat. The sensor will wait a few minutes after your cat exits the box to allow for a safe cleaning process.

Rotation: Once the wait time is over, the Litter Robot 4 begins its cleaning cycle. The globe rotates slowly, allowing the litter to sift through a grated mechanism that separates the waste from the clean litter.
