iRobot Roomba 2.1 robot vacuum I'm tired of it not picking up all the bits and I'm tired of cleaning all the brushes and wheels. It's time for it to move on and possibly be used as parts to resurrect your old Roomba. I bought a new battery a year ago, so if all you need is a battery, this could solve your problem. Do you need extra parts or extra virtual wall blocks or a new docking station? I've got it all.
