So I bought a Polaris 9400 and it's worked pretty well. Went to run this weekend though, and having trouble. Press a cycle button, the cycle lights up, cleaner does nothing. About ten seconds later, the cycle lights flash.
Took cleaner out of pool, and I can hear that it buzzes for about 1 second when you first hit the cycle, but that's it. Prop doesn't seem to move.
I've tried the standard things of unplugging power controller, unplugging power cord to robot and blowing on it and screwing that back in.
