There's good advice for maintaining a Rumba, tried some of them myself to little avail. Ultimately opened up gearbox removed the gears cleaned meticulously and reapplied lithium grease. I noted there are two small steel-bushings 2 of the gears fit inside. They're inside the gear compartment and they do pull out. One of them still spun freely, the other seized up. Cleaned out all the crud and soaked in WD-40 and applied lithium grease. For now it seems to be working fine, but instead of just ordering new rollers or brushes, check out those little steel bearings if replacing the brushes and rollers doesn't work
