iRobot Roomba s9158 – Plus.Parts® Replacement Brush Pack

The iRobot Roomba s9 range was iRobot’s answer to the cleaning gaps that round robots leave behind: the strips of debris along baseboards, the corners that a circular brush can only partially reach. The D-shaped body puts the brush system directly at the wall, and PerfectEdge Technology maintains that positioning as the robot navigates. The iRobot Roomba s9158 also brings 40x Air Power suction to the equation, enough to pull embedded pet hair from carpet pile and fine particulates from grout lines on a single pass. What makes this all work is the dual multi-surface rubber brush pair: two counter-rotating rollers that feed debris into the suction intake in tandem, with a rubber compound that conforms to different floor textures rather than skating over them. Over time, the rubber stiffens slightly, the contact quality softens, and the feeding efficiency drops. None of that is a defect: it is the normal end of the service interval, straightforward to address with a brush replacement.

This replacement pack contains Plus.Parts® dual rubber brushes designed as a direct-fit alternative for the Roomba s9158’s standard specification. Both brushes mount to the original attachment points with no modifications, restoring the counter-rotation system to the performance the s9158 was built to deliver.

The rubber compound in these brushes maintains its flexibility and floor-contact profile across the full service interval, matching the performance standard of the factory parts. The team behind this product answers compatibility and delivery questions personally; any issue with an order gets sorted out quickly.
