Litter Robot 3 slow flashing orange light

Help & Support Domestic Robots

Hi.
I have a litter robot for a number of years and it has been playing up recently.

The light stays flashing orange and it won’t cycle. I have followed the instructions online and typically I need to remove the bonnet and clean the two metal pins in the base whenever I want it to cycle. This is ok for a while and then it goes back to the orange light. I am doing this every day sometimes multiple times a day. I also make sure that the pinch sensors are clean and touching.

I have also cleaned the circuits in base which has also helped.

The night light doesn’t work and hasn’t for some time.

The flap in the bonnet that moved when the litter is cycling is in the wrong place and loose so I need to move this manually when the litter is cycling in order for the waste to dump in the bottom.

What parts would I need to fix these issues or do I need a whole new unit?

Hello,

Thank you for contacting RobotShop. To resolve this issue, please follow the steps in the attached video: https://www.youtube.com/watch?v=u0jVRoijTk0

Other steps to follow:

1-Make sure that the cable linking the night light under the bonnet is properly connected.

​​

2-Please test if the night light is interrupting your cycle. If the night light turns on and the cycle is interrupted, then your bonnet needs to be replaced.

*To activate the night light, turn off and then on the room lights in the evening. During the day, you can create shade by covering the control panel near the power button with your hands.

3-Make sure that the 3 connectors on the circuit board are properly connected.

​

If none of the steps resolves the issue, please send us photos of the 3 sets of contact pins. Two are located on the base, and one is on the side of the cover. (Refer to the photo)

Regarding the night light, here is a video to help you understand how it works, so you can activate or deactivate it as needed. * Litter-Robot 3: Night light feature

Regarding your last question, could you please send us a video or some photos showing the situation so that we can better understand what you are referring to?

Awaiting your response,

Kind regards,

Hi
Thanks for coming back to me.

I checked the 3 pins in the circuit and they were fine.

Attached are photos of the 3 sensors. The robot seemed to work when I cleaned the sensors with vinegar, however within the last two weeks I have been doing this a few times a day.

I tried to take a video of the problem with the flap but during the cycle, the litter robot packed up all together and won’t power on. I think maybe it’s time for a new unit!

Hello,

Thank you for the photos!

Actually, your unit still seems to be in very good and usable condition. It just needs a few parts replaced to make it like new. Indeed, all three pin assemblies need to be replaced (in addition, we noticed that the anti-pinch pins don’t even seem to be connected in their proper position).

Regarding the flap, the manufacturer removed this component several years ago because it was deemed unnecessary and became unhygienic. So you can remove it from your unit. Here is a video that will help you proceed. * Litter-Robot 3: Removing the internal shield

Additionally, we noticed that the PVC liner of your unit should also be replaced, as it appears very worn from cat scratches.

So here is a summary of the analysis of your robot:

After analyzing your robot, we can confirm that the problem is with the 3 sets of pins.

These pins should be replaced every 1-2 years as part of regular maintenance to ensure the robot functions properly. These components can rust or corrode over time due to ammonia exposure.

In order to help you repair your robot as quickly as possible, we recommend that you purchase the necessary replacement parts from the RobotShop website:

-Litter-Robot 3 Open Air Bonnet - Terminal Pins: RB-Ltr-108

-Black PVC Liner for Litter-Robot 3 Open Air Globe Assembly: RB-Ltr-109

Here is the video explaining how to proceed:

Hi there

Thanks for coming back to me.

Why does the Robot 3 Key & Plug Kit need replacing? Also what about the issue now in that the unit will not turn on? I don’t want to replace the parts if the unit will not power on. I suspect it is something to do with checking the circuit board.

Thanks
