Under normal circumstances when your Roomba complains with the "Please Inspect and Clean Roombas Brushes" the firmware progam that monitors the amount of power consumed by the brush motor has detected an excessive amount of power is being used and shuts the Roomba down and makes that announcement.  In a lot of cases this is due to the brushes being dirty or the end caps (Yellow Plastic) on the large brush are too tight on the brush housing.  Another condition is the buildup of debris inside the very small yellow bushings (one on each brush).  Always remove the brushes and the yellow bushings and clean them after every cleaning cycle.  This will lead to a long life for your Roomba and the Cleaning Head Module.

Now once you have inspected and cleaned the brushes and you are still receiving the message, "Please Inspect and Clean Roombas Brushes" there is one more major reason.  Due to the basic design of the Cleaning Head Module, (CHM) dust and debris can enter into the brush motor gear assembly and cause the motor to expend a lot of energy trying to turn the brushes.  This condition causes the same error condition as dirty brushes but cannot be resolved by cleaning just the brushes.  Now you must dis-assemble your CHM, remove the brush gear assembly access plate and clean out the built up debris.

Warning....These ball bearing sets will not just fit into the brush deck gears.  There are modifications that MUST be accomplished to both the gears and the gear openings so that the ball bearings will fit.  If you do not have the tools or don't want to do the work, then do not order just the 3 bearing sets, they will not fit !

There are a few choices that one can make at this point.  You can order the "Standard" 3 Sealed Ball bearing set and do your own mod.  You can send your CHM in for the ball bearing mod, or you can purchase a CHM with the mod already done.  The first picture set you see is for either the "Standard" 3 ball bearing set that can be ordered for $25 including USPS shipping or the "Flanged" 3 ball bearing set that has a flanged small brush motor gear and can be ordered for $28 including USPS shipping. Benefit of using a flanged ball bearing is that it allows for a fudge factor when enlarging the opening to insert the small bearing that is used on the brush motor.  If you want international shipping add another $3 to the total.  Just paypal to this address:  e_vickery@bellsouth.net
