The Illuminated Cat Sensor A Waiting Game

An illuminated red light on the Litter Robot 3 indicates that its Cat Sensor detected your pet entering the globe. This sensor ensures the unit does not activate a cleaning cycle while your cat is inside. Once your cat exits, the system goes into a ‘waiting time,’ defaulting to a 7-minute countdown before initiating the cleaning cycle. 

For users, this is a straightforward process. No immediate action is required, but if you wish to intervene, simply press the reset button. This cancels the wait time, resetting the Cat Sensor, and the unit will revert to standby mode, signified by a blue light.
