Appendix C : Module Inspection and Cleaning
DRIVE WHEEL Module inspection and cleaning
Check the wheels for obstructions.
Push the wheels up and down several times and shake out any loose debris that may be trapped
in the wheel well.
Make sure the wheels turn freely.
If there is uneven resistance between the wheels, hold down Roomba’s SPOT and
DOCK buttons for 10 seconds to reset the robot and try again.
Check tires for wear and tear.
If tire treads are no longer visible, or if large tears are present, replace wheel modules.
If wheel module problems persist on flat surfaces when there are no obstacles present, replace
wheel modules.
FRONT WHEEL Module inspection and cleaning
Flip robot over and hold wheel and pull out the entire front wheel module.
Look in chassis hole and clear away any fuzz or debris that is blocking the two
sensors located
under the front wheel module.
Remove wheel from housing and clear any hair wrapped around axle.
If necessary, slide axle out of wheel and wipe axle clean.
If white half of wheel is dirty, wash wheel and wipe clean.
Reinsert wheel into wheel housing and drop module back into Roomba
Do not forget to reinstall wheel - it is possible for Roomba to run without it! Grasp housing
with both hands and firmly press wheel into housing until both sides of axle snap into place.
