I will add the companion guide for lazy people.
Step 1. Fire up your air compressor and attach a blower nozzle.
Step 2. Take the Roomba outside. Blow into everything you can. Dust will come out.
Step 3. Clip the wound-up hair out of the brushes, blow 'em clean again.
That's it. If you've got compressed air, maintaining a Roomba is simple. You could also just use that canned-air duster thing you have sitting next to your computer keyboard.
As far as problems go, only two problems ever seem to occur in real life. The battery is obviously one. The other is a failure somewhere in the cleaning head gear train. This is solved by simply replacing the cleaning head, a five-minute repair requiring a part you can buy on eBay for $50. Now you don't have to worry about taking the cleaning head apart and refurbishing it, because you're lazy and have money. Go ahead, do it the easy way. Get a new cleaning head, blow some compressed air through it while you have it apart, and your bot will be good as new.
