I am trying to replace the worn main brush motor gear in my Roomba. The parts available on your sight do not look the same as the gear that was installed in the model I own. Can you guide me to an appropriate replacement for the Model 552 gear?
You are looking to replace the gears inside the motor or inside the brush casing? We currently only sell replacement gears for the 400 series robots and this may be why they are not the same. These gears are unfortunately not interchangeable between models.
For appropriate parts for your robot you must look for Roomba 500 & 600 Series Parts.
