FAQs

Cleaning the DFI sensors
Debris, such as dust or cat fur, can interfere with the DFI sensor. This can cause the unit to inaccurately trigger a drawer-full indication.
How often should I clean the litter in Robot 3? ›
However, you'll still want to clean the Litter-Robot's globe every 1-3 months. We also recommend deep cleaning your Litter-Robot 4 or Litter-Robot 3 approximately three times per year, depending on your personal preference and your cat's behavior.

What is the sensor on the Litter-Robot 3? ›
The Litter-Robot 3 is equipped with a cat sensor that detects when a cat enters and exits the globe. If a cycle is interrupted or the bonnet is removed, the unit will stop, and the yellow light will flash slowly, about 1x per second. This will also occur if the cat sensor is activated by a cat entering the globe.
Check for obstructions blocking the drawer full indicator (DFI) sensors. There are two sensors inside the base, above where the waste drawer would sit. Debris, such as dust or cat fur, can interfere with the DFI sensor. This can cause the unit to inaccurately trigger a drawer-full indication.
