My Dolphin X30 has been in the garage for almost a year and I recently started using it.
I noticed it was just doing small runs and then it would lift off the bottom and half float then go back down and do small runs again it did three cycles and didn’t pick anything up. I started troubleshooting and opened the motor block there was no sign of water leakage and it was completely sealed. I thoroughly silicone-lubed the o-rings and inspected the propeller servo and driving servo motor, couldn't fault any. Unfortunately, the Maytronics cleaner is still acting up and I am not clueless about what might be the root cause!
Video and photos of the issue.

Basically, the steps I have done.
* Inspected the motor block
* Opened and inspected the impeller motor, There was a bit of carbon but the brushes were still good.
* I did a continuity test on the cable, and all were okay.
These topics I found useful if someone in future is reading this thread and facing the same issue.

Maytronics drive motor 5521259-1 disassembly and repair
Hi everyone, I have a Prowler 920, which uses the Maytronics drive motor 5521259-1. It is not working, and I've narrowed it down to the drive motor; it spins freely, gets stuck and becomes very hard to turn. I've seen a helpful video on how to get to the impeller bearings, but how on earth do...

Time for Maintenance of "Robotina" Maytronics S200
A little history, Robotina was bought 3 years ago from a seller on Ebay. He listed it as a Refurbished unit and got about 200 bucks savings from a new one. At first few months Robotina would live 1-3 days underwater. I got lazy and let her live 24/7/365 except for few minutes while wash down and...
