Introduction
This guide explains how to replace the side brush motor on the iRobot Roomba 630. The motor may need to be replaced if it is damaged or defective.
The side brush motor attaches to the side brush to make it spin, which helps sweep dirt and debris from hard-to-reach corners into the vacuum's suction. Before using this guide, you may first check whether debris or hair is caught in the brush or motor, preventing the motor from spinning. You might also check to see if the motor is poorly lubricated, which can prevent it from spinning. If the side brush and motor are clear of debris but the motor is still not working, the motor may be defective.
