Nah, that's a feature, not a bug. A flashing blue light ring means it's in Dirt Detect mode. It found a particularly dirty area and is working harder on it.
WHAT'S HAPPENING
The robot is moving over the same area multiple times until its sensors indicate the area is clean. This is normal. Let it finish.
OTHER BLUE LIGHTS TO KNOW
- Solid Blue Spiral: You pressed the Spot Clean button. It will clean a 3-foot (1-meter) diameter area and return to start.
- Pulsing Blue: You pressed the Home button. It's navigating back to its Home Base.
IF IT'S ACTUALLY STUCK
If it's circling because something is jammed, it will eventually stop and show a solid red error light. Then press CLEAN to hear the audio alert. Common jams are in the brushes or front wheel.
HEADS UP
For the best Dirt Detect results, use the robot frequently to maintain well-conditioned floors. Remove excess clutter before it runs.
