Have a client with a 2021 vintage Matronics Triton robotic cleaner that last summer had the cabe severed by getting caught in the auto pool cover. The maytronics oem blue cable was purchased and repaired. After the repair it wouldn't move so the controller was opened only to find it had been damaged by water intrusion and possibly the cable mishap. Before any more money is spent here such as buying a new controller I'd like to be sure the robot itself is working. My question is, Can any dolphin controller be plugged in or are there different controllers for different models but I'd assume that more then one model shares the same controller. Anyone with knowledge of this will be greatly appreciated. TIA, Allan
