DFI Installation


NOTE its highly recommended you replace the Pinch Detectors as well as the DFI, as pinch detectors are subject to wear and tear and corrosion due to location.


Litter-Robot III Pinch Detector Terminals (2pk)

Replacement anti-pinch pins, or Pinch Detectors, for Litter-Robot III Open Air


Note it is recommended that pinch detector terminals be purchased if an upgrade kit or replacement DFI is purchased, as pinch detectors are subject to corrosion and debris, due to location in the the waste drawer cavity.

DFI kit includes pinch detectors.

NOTE touch points (heads) can be cleaned by pressing on the cover (DO NOT PULL as fragile by design and not covered by warranty if broken) to open the gap between heads. Wipe with a dry earbud or Qtip. If more cleaning is needed, a very light sand with fine sandpaper, emery board or similar to remove any corrosion or dirt, so there is good contact for power flow can be done, but replacement will be needed if sanded/abraded. Photos for review can be submitted at



Ask a Question
  • What can cause the DFI to fail?

    The DFI (narrow green circuit boards) can fail due to a manufacturing issue, which would not necessarily show any sign of issue. However, a more common visible issue is litter related, not manufacturing. Clumping litter that forms clean easy to scoop clumps is best to keep the appliance clean and low maintenance. 

    For the DFI, if litter is not clumping well, both the electronic board and the metal parts, pinch detectors, can be affected as uric acid in the urine deposits is best captured and contained in good clumping litter. Poor litter will release more uric acid in the waste drawer cavity, resulting in more smell issues and also corrosion. Poor clumping will also mean the globe is not kept scooped clean of soiled litter and odour and cleaning will increase. Poorly clumped soiled litter can also be distributed into unexpected areas, causing damage to components, and again, more odour.

    Review the pinch detectors, with the touch points the part that needs to be clean for good power flow. DO NOT PULL on the cover as delicate by design and easily broken (not warranty).

    Review the DFI left side board near the pinch detectors, for dust or debris both on perspex cover, and on the board itself. In particular, check to see if there is visible darkening on the silver chip pins left side of the black midboard chip square.
    The board has a clear resin coating, and it is worth cleaning any dust or debris off cover and board itself, as it can cause DFI issues.
    Turn off and unplug the Robot by removing the power supply from the back of the base (this also refreshes the software).
    Using a damp earbud or qtip, stoke outwards along the bars to clean off any material. Damp the earbud using clear alcohol or similar non-residue cleaning fluid, and then wipe the same way using the dry end to ensure there is no moisture left.
    Please also add a vertical strip of household sticky tape to just cover over the midboard opening to help with litter clumping and dust issues if you are not using good clumping litter. Apply starting above the board and you can wrap down and back up the rear.

    This may restore function but photos of any damage are able to be reviewed if provided to

Superstar Service!!

After having my litter robot for 2 years, it started to have issues. Speaking to Mary (whom was very prompt at responding), I realised that the catsan litter I'd been using was not clumping as it used to and was catching on the circuit boards causing damage over time. She gave me some helpful steps to ensure that it could be resolved first without needing to replace parts.
Unfortunately it had to be replaced however, Mary went above and beyond to ensure that my litter robot was not out of action for long. As we're both located in WA, I was able to travel to her and have it replaced (and cleaned!) within an hour.
I'm so grateful for all her tips and amazing service that I can't help but highly recommend to everyone!

Easy Installation

A little bit fiddly but easy Installation. Followed the YouTube tutorial which was simple and concise. Very quick arrival and backup and running like a charm in no time at all. Definitely worth going down this route for time and convenience. Customer service was excellent, can't recommend enough.

DIY DFI kit to fix my flashing blue light issue

I just wanted to let you know that I have fitted the DFI sensor and replaced the pinch sensors and now my litter robot 3 is working again. Thank you for your prompt and professional service, you were a great help in this matter.

Customer review

Thanks so much for your help. I was able to fit all the new parts fairly quickly. The machine is now back up and running, and my cats are very happy.

I reckon it was the pinch detectors. They were very corroded, and it was hard to see that without taking them out.
