Current state -
Power works, appears that Pump motor works (propellor works) when in pool, but cleaner doesn't move. Manually try to move wheels, but very hard to move them manually. Removed side panels, drive belts look good.
My feeling is that the drive motor is pooched.
Questions - Can the drive motor be replaced independent of the Pump motor? What is the situation with parts for iRobot.
We inherited this unit from previous owners. Worked only one season, then last year it stopped working.
