  2. I have a dolphin s300i that does not move, but does vacuum debris. Intermittently, it will try to move, but only a few inches. The light on the robot flashes blue/red/green the entire time that it is on. The track seem free and clear of debris. The power center is steady blue. Does this unit need a motor?
