The roller is an essential part of vacuuming. The robot uses this part to disturb debris embedded in the carpet and vacuum it up. The robot has on-board diagnostics that trigger the Maintenance Screen (a picture of a wrench) when something is wrong with the roller. If the roller has been cleared of debris, these steps are a safe option for fixing other roller issues.

Instructions
Remove the Brush Roller
-
Turn off power to the robot with the switch located under the corner next to the battery compartment.
-
Remove the battery.
-
Turn the robot over so that you can access the roller(located at the front of the robot).
-
Loosen and remove the 4 screws using a Phillips 1 screwdriver. Take out the retainers. Set the screws and the retainers aside.
-
Carefully remove the Full Brush Roller from the Intake.
CAUTION - Make sure you do not drop the Inner Roller Core out of the Outer Brush while removing.
Disassemble and Readjust
- Carefully pull the roller core from within the roller brush.
- Unscrew the motor screw (located on the spider coupler end of the roller core) about half a turn.
-
Optional: If you have Loctite, completely remove the spider coupler screw and apply blue Loctite 242 to 3/4s of the screw and screw it back in. Otherwise continue to the next step.
Re-assemble the Brush Roller
-
Slide the roller core back into the roller brush. You may need to twist the assembly until the spider coupler lines up properly.
-
Check the the roller's fit with the bot. It should have a slight resistance against the side walls as it is being installed. If this is not the case, repeat the steps in Disassemble and Readjust until the proper fit is reached.
-
Re-position the roller retainers and screw with the 4 Phillips screws.
-
Flip the robot back over and you're ready to roll!
