Hi
This is a great product, i got mine two weeks ago
But i have a problem, after each use of the robot the blue light starts to flix meaning the drawer full, even after a single use
That and when in this state the robot will not clean the litter

How can i disable the sensor so it will never show as full drawer?

Hi, note that you cannot deactivate the drawer full indicator. It is connected directly to the circuit board and trying to bypassed this security sensor might void your warranty.

Please try the following:
Once resolved, the unit should consistently recognize when your cat visits and cycle accordingly.
To troubleshoot the blue blinking, let’s start by power cycling your unit: 1.) Leave your unit powered ON with the blue blinking light engaged & Unplug your power supply from the base 2.) Wait 10 seconds then plug the unit back in
3.) Allow the unit to complete a start‐up cycle. If the light is solid blue, the code has been successfully cleared. If the light is still blinking, let’s proceed with troubleshooting. Let’s empty the drawer if it has waste and reinstall the bag before proceeding.
Note: If you are using a dark colored bag, always tuck it into the tabs.

Let’s check your DFI Lenses for any obstructions:

  1. Turn off the unit and Unplug the power from the base
  2. Remove the Bonnet and the Globe 3. Inspect the top of the Base where the Globe usually rests. Are there any debris? Small amounts of litter is normal. Clean as needed. 4. Inside the waste opening there are two clear “Lenses” (left and right side). Ensure there are no debris on the Lenses. Sometimes litter can fall/splash onto them. ** To clean the lenses, we recommend wiping them off with a soft damp cloth and/or glass cleaner. Do not directly spray the Base or DFI Lenses. ** 5. Replace the Globe and Bonnet. Reset the black key in the back of the unit into the pocket. 6. Plug the unit back in. If you turned the power off, you will need to power it on and press “cycle”. Once the cleaning cycle is complete, the unit should be at the Home position with a Solid Blue LED on.

Further Troubleshooting:

  1. If the unit continues blinking blue, remove the waste drawer and press cycle. 2. Press reset 2x to abort the cycle and return the unit to home (it will level the litter). 3. If the unit goes to solid blue with the waste drawer removed, ensure there is nothing in the drawer blocking the lenses. 4. If the drawer is clear, your base needs to be repaired ‐ let us know that you tried the full troubleshooting without results.

Hi, mine’s having the same problem and I tried all of the above troubleshooting but the blue light still keeps flashing. It continues to flash even when the waste tray is removed. What can I do?

Hi Weilan,

Have you verify the lenses on each of the DFI sensors?
Make sure they are perfectly clean, dry and transparent.

If the issue persist, I suggest you contact your dealer for warranty or else you can always replace the DFI sensor by yourself using these 2 links:
