Guys I have an MX6 pool cleaner that moves sometimes and when it dies it is very slow. I was on YouTube and it says to check for a blockage but it is not blocked and I have it on the suction side of the pool. (the hole inside the pool. I have heard to look towards the diverter valve to turn to make it faster however ai am not sure which one that is and am hoping someone could identify it for me. Thank you
