The brush is intended for routine maintenance and timely replacement when wear reduces effectiveness.

Advantages

The three-arm design improves contact with baseboards and tight corners, directing dirt toward the vacuum’s main cleaning channel. Manufactured to match the fit and function of original side brushes for the listed Roomba Combo models, it offers straightforward installation and stable rotation during operation. Using a compatible replacement side brush helps preserve cleaning coverage along walls and in narrow gaps without requiring tool-assisted adjustments.

How to use

Turn off the robot and follow the manufacturer’s instructions for removing the worn side brush from the designated mounting point. Align the replacement brush’s hub with the mounting post and press it into place until it clicks or seats firmly. After installation, run a short cleaning cycle to confirm proper rotation and edge contact. Inspect the brush periodically and replace it when bristles show significant wear, bending, or fraying that reduces sweeping effectiveness.

Usage recommendations

For optimal results, replace the side brush at the intervals recommended in your robot vacuum’s maintenance guide or sooner if you notice reduced edge pickup. Keep the mounting area free of hair and debris, and inspect the brush hub for obstruction to ensure smooth rotation. Store spare brushes in a dry place away from direct sunlight.
