Roborock Error 5 — Main brush jammed
DIRECT ANSWER
COMMON CAUSES · RANKED
Hair wrapped around the roller MOST COMMON
Long hair and pet fur wind around the brush body and pack into tight bands.
Debris in the bearings and end caps
Hair hidden inside the two end bearings stalls the brush even when the roller itself looks clean.
Object jammed in the brush slot
A sock edge, cable or toy piece caught in the brush housing locks the roller solid.
HOW TO FIX IT
Keep fingers away from the blade edge of the cleaning tool while cutting tangled hair off the brush.
Remove the main brush
Flip the robot, press the latches on the brush cover, and lift the brush out.
Cut away tangled hair
Use the cleaning tool's blade to slice hair bands along the roller, then pull them off.
Clean both bearings
Pull off the end caps and bearing, and clear the hair packed inside — this step is the one most people skip.
Check the brush slot
Look inside both installation slots for jammed objects before refitting the brush.
Refit and test
Reinstall brush and cover until they click, then run a short clean. Roborock suggests testing with Carpet mode enabled.
