Anyone have any idea why they have those extra pieces of plastic at the ends of the feet? Looks like there's plastic pieces that align with the three circles, but I can't see any reason they did that. Just one more extra piece to break off...
RstyKnfeThat's exactly what they are.
They snap onto the legs via those holes there.
I don't imagine them breaking, unless your Roomba has a spinning tungsten blade on top of it.
I will admit, they're a pain to remove. You must make your decision beforehand if you want them on or not.
