The iRobot Roomba s9+ was iRobot’s flagship: a D-shaped robot that pushes its 40-per-cent-wider rubber rollers straight into corners and pairs with a Clean Base dock that empties the bin into a sealed bag after every run. You invested in one of the most capable robots iRobot has made, and that performance only holds while the parts doing the actual cleaning are in good condition: the dock automates the bin, not the brushes or the filter.
This set keeps the s9+ working to its specification. It contains Plus.Parts® parts made as a direct-fit alternative to the original iRobot parts 4655986 / 4646124 / 4655987 / 4646490 / 4655988 / 4643682 / 4655989 / 4646123: two Dual Multi-Surface Rubber Brushes, two Corner Brushes, four high-efficiency filters and a cleaning tool – nine parts in all. The Dual Multi-Surface Rubber Brushes lead the set: running at full suction in a busy home they harden and lose grip on carpet over months, and iRobot advises replacing the pair at six months in those conditions, so two fresh rollers reset pickup straight away.
The rollers use a compound that stays flexible far longer than cheap alternatives, the filters hold a tight 10-micron weave that traps allergens instead of recirculating them, and the included tool makes the regular roller clean fast. The Clean Base bag is sold separately; this set covers the brushes and filters, and the VacuumReviews.eu team will confirm any fit question.
At a glance
- Consistent Performance – Fresh rubber rollers, Corner Brushes and filters return the Roomba s9+ to the suction and corner pickup it delivered out of the box.
- Built to Last – Flexible rubber compounds and high-density filter media are chosen to hold up through months of daily cleaning at the s9+ suction level.
- Reliable Quality – Each component is produced to a consistent standard and inspected before dispatch, so it fits the s9+ and performs as described.
