I've had this cleaner since November 2020. Until about two months ago, I rarely had any issues with the cord. But now it is tying itself into a knot at least once a week and the cord gets pulled through the front roller pretty often. I can usually pull the cord out and get it untwisted/untangled in less than 5-10 minutes. However, it recently was so bad that I spent an hour trying to undo the knot. It is also not practical b/c it basically sidelines the cleaner until I get it sorted. I work long hours so I'm not outside at the pool every day. The cleaner went from being virtually worry-free (minus cleaning out the debris) to now I'm dealing with the cord 1-2 times per week. Any suggestions?
