I have an Aquabot that keeps getting tangled in the cord. It seems that maybe the cord floats into the path when it is scrubbing the wall. I don't know for sure because I have not seen it happen as the robot usually gets run at night.

I have had this robot for five years and have never had this problem before. I am very familiar with its parts and workings. I have replaced all of the replaceable parts (scrubbers, bands and tracks) over the years. Otherwise it is working fine.

Any thoughts?
