Keeps throwing a code 2 to empty trash

Error 2 on an iRobot Roomba 980 usually means that the rubber brushes are clogged and need to be cleaned. The most likely cause is hair stuck on the brushes, which is preventing them from spinning properly.

To fix the error, you can try these steps:

1. Clear the brushes
2. Pull the extractors out, clean any debris/hair on the ends, and pull the yellow end caps off
3. Press the CLEAN button to restart

If the Side Brush is not spinning after cleaning, you may need a replacement Side Brush Module.
