iRobot Roomba Combo j9+ – Plus.Parts® Dual Rubber Brush Replacement

The iRobot Roomba Combo j9+ is the top-tier model in iRobot’s Combo line, combining the highest suction rating in the series with a retractable mop arm and auto-empty Clean Base. The navigation system builds detailed floor maps for room-by-room scheduling, and the j9+ typically runs on frequent automated schedules, placing regular demands on every consumable in the cleaning path. The dual rubber brush system is the first contact point for all floor material the robot encounters: two counter-rotating rollers draw debris inward and upward toward the suction port. Because the j9+ operates at a higher suction level than earlier Combo models, worn brushes that fail to agitate debris correctly become a more noticeable performance bottleneck than on lower-power platforms.

This dual rubber brush replacement is sourced by Plus.Parts® and contains two brushes sized and profiled for the Combo j9+ brush module. The end-cap fittings, centre gear and roller diameter match the original, and the rubber compound along the contact face of each roller corresponds to the original specification. Replacing both brushes as a matched pair from the outset means the counter-rotation system is balanced from the first session of the new cycle.

The rubber compound is selected to maintain surface flexibility under the higher operating demands of the j9+ platform, supporting consistent floor contact throughout the replacement interval. VacuumReviews.eu reviewed the set for the Combo j9+ and the team is available for any variant-specific question.

• Long-Lasting Components – The rubber compound is selected to maintain surface flexibility under the higher suction and daily-schedule demands of the Combo j9+ platform throughout the replacement cycle.
