@baldly Roomba 700 and 800: When in Dirt Detect mode, the blue Dirt Detect indicator will flash. You did not tell us which light. The dirt detect is the magnifying light. Make sure that you check the brushes and clean them well. If there is debris stuck on those they may trigger the dirt-detector sensor and you get your blue light flashing.
