Most common causes:
The side brush module has entered anti-tassel behavior. The side brush
may spin slowly or briefly spin backwards in order to escape from carpet
tassels or wires. The robot may occasionally enter this behavior on thick

Troubleshooting:
•
If this behavior is observed on hard floor surfaces or when no tassels or
wires are present, try cleaning SIDE BRUSH Module (Appendix C).
