One of the quickest repairs for bObi is replacing the main brush motor. To do this, you'll need a Phillips head screwdriver and a replacement main brush motor.

During all of bObi's repairs, always keep screws and parts aside and organized. Many of the screws are not interchangeable due to size differences.
