Question about iRobot Roomba 4210 Bagless Robotic Vacuum
2 items: comtinual shut down for brush cleaning after repeated cleaning and a wheel thump that just started after cleaning brushes
Rchu is exactly right. No need for a complicated disassembly. If you have never pulled off those end bearings/caps, the hair may be very impacted, but removing it should solve the problem. The instructions will tell you by color (yellow for mine) which pieces come off for cleaning. Be sure to remove all such pieces. If the fit seems tight, it's probably because a lot of stuff got stuck in there. Be gentle but firm, and things the should come off will come off. Once you've cleaned all the pieces, the thumping should be gone.

Remove the Yellow connectors on the end of the brushes and clean around the pin well. If there is too much there, the roomba thinks there is something stuck and goes into clear mode (as if there is a chord stuck).

Make sure you take off the little cap at the end (the one that spins -- just grab it and pull it straight off) and clean under it too. The rest of the brush may look perfectly clean but what happens is that hair gets stuck under spinning cap and, like a slowly growing washer, it pushes the whole brush toward the gear box. When it gets pushed over enough, the large yellow ring starts to rub against the side of the brush deck making it harder for the motor to turn the brush and you get that "remove and clean brushes" message.

I decided to take it apart and see if I could fix it because even if something inside went "SPROING" and I couldn't get it back together, it wouldn't be any worse than it was already.
FIrst, remove the dust bin part and the brushes. Then, there are four screws on the bottom gray panel which have to be removed first in order to get to the gears which hold the brushes. I did not remove the little sweeper brush on the front, but I just slide it through the hole in the gray panel.
Then in order to get out the orange section which actually holds the brushes, there are four screws which must be removed. The orange section is attached to a blue section. This entire unit comes out by sliding it toward the area where the dust bin goes, being careful not to tear the light gray rubber gasket which covers the side.
Once that section is removed, there are two screws on each side. These screws hold the orange thing to the blue thing. Once the screws are removed, lift up only the side which has the white squares into which the brushes are inserted. These are actually the back side of little gears. There is a face plate on the outside of the orange part on this end. The other end contains a bunch of wires and I was careful not to disconnect any of them.
The face plate has six screws which must all be removed. Use caution when removing the face plate. Hold it up so that all of the stuff doesn't fall out. It has a bunch of gears, little brass looking fittings and grease. Take care to only remove the gears which have the squares which hold the brushes AND do it one at a time unless you like working jigsaw puzzles. I used tweezers and a pin to clean the "gunk" consisting of hair, fuzz, etc., out of the little gears.
Reverse the process to put it back together. Hazel, my little Roomba, played me a happy little song and immediately went back to work. She seems as good as new.

The dust build up in these Roomba's do create a problem in all operating phases
Keep in mind if taken apart every 6 months and cleaned inside they will operate like they should
