My M600, less than 18 months old dead yet again. Power to the power supply, blue light showing its should be running, no lights or movement. Connecting to the app it says the robot is off and will not turn on. No water intrusion in the cord this time. This will make the 5th trip back to Maytronics for repair and costing about $70 for shipping. For a $1200+ robot this is unacceptable.
