How to Modify Cliff Sensors so they never signal a cliff

Introduction

I live in the country with Dogs, Cats, Dirt, Mud and no cliffs. We do have dark knotty LVP flooring. We launch our Roomba every night at 1:00am… This is my second one and over the last few months the cliff-sensors (which are not sealed) continue to say “Eek! Cliff!” right in the middle of the floor… Sometimes after traveling 1-2 feet from the last falsely detected cliff.. Since the dust has built up inside the sensor wiping and cleaning the sensors made no difference.

Before throwing out the Roomba I decided to perform one-way surgery on the cliff sensors in order to completely disable the ability of the Roomba to detect a cliff

What you need

Step 1 Follow the disassembly instruction of another fixit

Step 2 Disassemble the sensor Clean or Continue

The sensor is easily disassembled by lifting the two small plastic latches on the side. Once the cover is removed you could clean the sensor and replace it....
Since I'm very tired of Error-6 messages and will not be adding stairs to my dirty house I opted to alter the sensor so that it will never detect a cliff falsely or otherwise.
These sensors work by emitting an IR light from one side and since there are baffles in the sensor it must bounce off a floor to reach the detector in the other side.

Step 3

THIS STEP CANNOT BE UNDONE.
I removed the baffles from the sensor so that the detector and emitter have a direct line of sight to each other
I used a small pair of wire cutters to cut out the baffles as needed
