Flashing Red Light: Cat Sensor Fault | Litter-Robot 4

Litter-Robot 4 is equipped with OmniSense™ detection that utilizes laser and weight sensor technology to provide real-time litter and waste drawer levels. OmniSense™ also supports the SafeCat system which continuously analyzes 4 safety zones to ensure your cat is always safe.
There are three laser sensors located in the top of the Bezel, as well as a cat sensor weight scale located in the Base of the unit. These sensors detect when a cat has entered or exited the unit.
If your unit has a red flashing light bar or the unit will not cycle, this indicates that the cat sensor has been triggered for more than 30 minutes. You will also receive a notification on your phone if you use the Whisker App.
The weight scale could be detecting additional weight added to the Litter-Robot. If you’ve recently moved or added litter, this could cause the unit to think a cat has entered and not exited.
This video will show you what to do when you experience this light pattern or app notification. For additional information or support, please visit whiskersupport.com.
