2. Installation Instructions
Before beginning installation, ensure your Roomba is powered off and disconnected from its charging base. It is recommended to perform this procedure on a clean, flat surface.
- Prepare the Roomba: Turn your Roomba robot vacuum upside down to access the bottom panel.
- Remove Side Brush: Unscrew and remove the existing side brush. This usually involves one screw in the center of the brush.
- Remove Bottom Cover: Locate and unscrew the four (or more, depending on model) screws securing the Roomba's bottom cover. Carefully remove the cover.
- Locate and Remove Old Module: Identify the old side brush module. It is typically secured by a few screws. Unscrew these fasteners and gently lift out the old module.
- Install New Module: Position the new caSino187 Side Brush Module into the designated slot. Ensure it sits flush. Secure it with the screws removed in the previous step.
- Replace Bottom Cover: Carefully place the bottom cover back onto the Roomba, aligning all tabs and screw holes. Secure it with the screws removed in step 3.
- Reattach Side Brush: Reinstall the side brush onto the new module, securing it with its central screw.

- Clean the Side Brush: Periodically remove the side brush and clear any accumulated hair, dust, or debris from the bristles and the brush post.
- Inspect for Wear: Check the side brush bristles for signs of wear or damage. Replace the brush if bristles are bent, frayed, or missing.
- Check Module Area: Ensure the area around the side brush module on the Roomba's chassis is free of obstructions.
