Based on the provided reference, replacing the side brush module involves accessing the area by removing the bottom cover and loosening specific screws.
According to the reference detailing steps for replacing the side brush (likely the assembly or module) on a Roomba® 600 series, the initial actions required are:
- Remove the bottom cover. This step grants access to the internal components, including the side brush mechanism.
- Loosen the two screws that retain the side brush. After the bottom cover is off, locate and loosen the two screws specifically holding the side brush or its assembly in place.
These steps are crucial for detaching the old side brush module or assembly from the robot's chassis, preparing it for removal and replacement with a new part.
