The iRobot Roomba s9 broke from every round Roomba before it with a D-shaped body whose flat front drives the brushes into right-angle corners most robots only skim. Its wide Dual Multi-Surface Rubber Brushes move noticeably more debris per pass than the 900-series, but the design that makes the s9 a strong corner cleaner also drives more wall contact and higher airflow, so the Corner Brush and filter both reach their limits faster than on a conventional robot.
This kit handles all of that wear in one go. These are Plus.Parts® consumables built as a direct-fit alternative to the original iRobot parts 4626194 / 4640235 / 4655986 / 4646124 / 4655987 / 4646490 / 4655988 / 4643682 / 4655989 / 4646123: two Dual Multi-Surface Rubber Brushes, two Corner Brushes, four high-efficiency filters, five Clean Base dirt-disposal bags and a cleaning tool – fourteen parts in all. The filter is the part to track on the s9: the wide rollers funnel more air through it, so it darkens to mid-grey within weeks in a pet home, and once it does the motor strains to hold suction, so four filters keep you on iRobot’s two-month schedule.
The rubber rollers resist heat hardening to keep their carpet grip, the Corner Brushes hold their reach into tight angles, and the five Clean Base bags are ready for the auto-empty dock the moment you add one to your s9. If you want your specific s9 region or revision checked, the VacuumReviews.eu team will sort it before you order.
