Litter-Robot 3 - Cat sensor issue

Hi!
I have the same issue with Litter-Robot 3 as some other people on the forum: red light is often on for long periods of time without any reason, then it starts a cycle, then it stops mid-cycle because it thinks a cat is inside and so on.

We’ve tried basic steps: unplugging it, cleaning it, making sure the surface underneath is okay, readjusting the bonnet… So I guess the next step is to change the Cat Sensor?

I have an active warranty from RobotShop. Who should I contact?
My order Number is #1305149, 9/15/2023

Thank you!

Hello @Mademoiselle_Che ,

Welcome to RobotShop community.

We are sorry to hear that you are having trouble with your Litter-Robot.

Your robot is covered by the warranty so we can certainly send you a new CAT sensor.

We will also need to see the 3 pairs of contact pins shown in the following video:

No need to take them out of the robot, we only need to see them from the outside.

Awaiting your reply.

Sincerely,

Hi Ebram!

According to the pictures, the bonnet and base contact pins are a little damaged so we will send you new ones along with the CAT sensor.

Hi Ebram!

We changed the cat sensor and two sets of pins, but unfortunatelly it changed nothing. We tried to screw the sensor a bit more tight or more loose, also to no effect.

What happens is: we plug it in, it starts cycling, and after 1 sec. it stops with yellow light flashing. Then it moves againg, then it stops again. Takes 3-5 minutes to finish one cycle. And 10 seconds later the red light is on again.

Here are 2 videos of this:

  1. IMG_1940.MOV - Google Drive
  2. IMG_1941.MOV - Google Drive

In the video you can see the unit on a table (clean, flat, steady), but on the floor it acts exactelly the same.

Also the blue light inside the globe is flashing from time to time. Does it give us any additional insight into what’s going on?

Please let me know what we should do next.
Thank you!

Hello @Mademoiselle_Che ,

Thank you for your reply.

We are sorry to hear that you are still having trouble with your Litter-Robot.

According to the error description there is an mix-up in the wiring so please provide us with pictures like the ones attached below to verify the installation of the parts:

Hi Ebram!
Here are the new photos.




Hello @Mademoiselle_Che ,

Thank you for your reply.

Please check the connectors of the base contact pins shown in the picture below and make sure they are not damaged and then fully insert the pins into them for better connection:
Base Contact Pins

Let us know how it goes.

Sincerely,

Hi Ebram!
I think it got worse somehow.

We made 100% sure that the pins are fully inserted and that connectors have no visible damage. Everything seems to be in the right place.

Now we have all of the same issues, plus also while spinning, the globe starts to go backwards multiple times.

I think at this point we should consider changing the whole base or reimbursement of the purchase. The robot worked for less then a year, and now we aŗe stuck for months with it functioning as a 3$ litter-box and spending every weekend reassembling it.

I add photos and videos of the unit. In the last video right after I stopped recording the red light on the button “timing” appeared again.

Hope we find a solution for this situation :frowning:

Hello @Mademoiselle_Che ,

Thank you for your reply.

Unfortunately, the exchange/refund options are only valid during the testing period (first 90 days of the purchase)

After that, we can either send you free replacement parts to replace at home or you can send us the robot for inspection and repair under warranty.

According to the videos, we recommend replacing the circuit board and the nightlight’s circuit board, however, if you don’t want to replace more parts at home, you can send us the robot for repair.

You will need to send us the base, the bonnet, and the power supply of the robot. No need to ship the drawer and the globe.

You can place the globe over the waste drawer and use them as a stationary litter box until the rest of the robot gets back to you.

We suggest a box dimension of 24 “wide x 18” deep x 24 "high. The Bonnet should be put in the box upside down on top of the litter base.

Awaiting your decision.

Sincerely,

Thank you for your reply.
Could you please send us tutorials for replacing the circuit board and the nightlight’s circuit board? I think we’ll be ready to give it another try.

Thank you!
