My warrior si randomly stopped working recently and doesnt look like it's getting power at the robot. The control box has power and the lights go blue to start a cleaning cycle but the flashing light on the robot doesnt come on and he seems dead. I've checked the motor and propellers to make sure nothing is clogging it up. The app states "No Mode" when its started. Has anyone come across this and know of a fix? Out of warranty unfortunately and really not wanting to buy a new robot, prices look insane from initial shopping around.
