some hardcore maintenance......copied from roombareview.com
As per request, here are some pictures of the tools I use as well as my cleaning area. Canned air can substitute for the compressor.
Table top 4ft on drop down bracket that holds 300lbs. No legs that way.

(NOTE HAIR ACCUMULATION ON RIGHT ROOMBA FLEXI BRUSH)
DAILY: 1. Remove bin and dump out - remove hair from bin teeth - tap dust off of filter. Use air compressor to clean both chambers and filter.
2. Remove both brushes and use air compressor to clean out wheel wells, behind plastic flap, in 4 openings for bumper front sensors and surface of brush deck
3. Pry out front wheel with flat screwdriver and then use needle nose to pull up and out wheel housing. Use air and brush to clean under it if needed. Remove hair from chrome axle ends and slide out axle and remove dirt from indentation in center. Replace all.
4. Remove spinning side brush and remove any debris from under it. Replace
5. Clean bristle brush by removing yellow ends and bearing. Remove hair and dirt from under bearing with tweezer and brush and in it's hole with straightened paper clip if necessary. Use tool to remove hair on brush and then use seam ripper, dog comb or air to finish cleaning bristles
6. Clean flexible brush by removing bearing and removing hair and dirt under it, use seam ripper to cut hair wrapped around middle and ends and rag to dust it off when done. Replace filter and brushes.
BI-WEEKLY:
1. Remove 4 large phillips screws from bottom plate
2. Remove side brush and all cleaning brushes and dirt bin
3. Remove bottom plate
4. Remove 4 smaller screws from around blue brush deck
5. Carefully pull up on blue deck and blue and red will come out (screws come out so be careful not to lose them) NOTE small printed circuit board connector on bottom.
6. Remove red pins from blue plastic on front edge by carefully prying blue apart a little - one at a time.
7. Turn over blue part and use air or tools to clean out fuzz from around brush motor and possibly on the shaft of it.
8. On left side of red plastic, remove all small screws that hold the gears in. Carefully place them aside for reassembly.
9. Remove outer red plate to expose gears being careful not to drop the white gears. This will be greasy.
10. Remove carefully two larger gears that the brushes fit into. Clean with tweezers or brush to remove hair and debris. Re-grease with lithium grease and replace.
11. Reassemble side plate with screws then pop red pins back into blue part carefully.
12. Carefully reassemble blue part onto Roomba by lining up screw holes and making sure the indentation at the bottom fits into the circuit board connector. It will pop in easily if the screw holes are aligned. Replace 4 smaller screws.
13: Replace bottom plate and you are done.
Once you have seen it and done it, the daily routine takes about 5 minutes and the longer one takes about 15 or less.
Hope this helps. It's all modular now so in the future I'm assuming the replacement parts will be sent as needed vs entire Roombas being shipped back.
