CLEANING HEAD Module inspection and cleaning

Check if main brushes are spinning by running the robot with the vacuum bin removed.
Remove Brushes and clean them if dirty.
Make sure both yellow main brush caps are installed correctly.
If not, send replacement brush caps.
Make sure the main brush and the flapper brush each have a yellow bearing installed correctly.
If not, send replacement bearings.
Check the square ends of both brushes.
If the square end of either brush is rounded, check the corresponding square recess in
the cleaning head module.

If brushes still do not spin after cleaning, or if error alert persists, replace cleaning head
module.

BUMPER Module inspection and cleaning

Gently tap both sides of bumper several times to shake out any debris that might be causing the
bumper to stick. Try cleaning around bumper with compressed air, if available.
If problem persists, replace robot.

CLIFF SENSOR Module inspection and cleaning

First determine that Roomba was not started on an uneven surface, or a dark surface that could
have triggered a false cliff or a continuous false cliff.
Turn the robot over and wipe all four cliff sensor windows with a clean, dry cloth.
Verify that the side brush is spinning properly during runtime.
• If not, troubleshoot the side brush module. The side brush could block the cliff sensors
if it is stalled.
If cliff sensor failures persist on flat surfaces with no cliff sensor obstructions present, replace
robot.
If Roomba is no longer able to avoid stairs, replace robot.
If the either brush is rounded, send replacement brushes.
If the either square recess is rounded, replace cleaning head module.
