The iRobot Roomba s9550 is an alternate retail SKU for the Roomba s9, built on the same D-shaped platform with the same Dual Multi-Surface Rubber Brushes and high-efficiency filter as the rest of the range. Its strength is reaching debris in corners and along skirting that round robots leave behind, and the wear pattern follows from that: heavy wall contact tires the corner brush, and the wide rollers push more air through the filter than a conventional Roomba.
A single refresh kit resets all of that. These are Plus.Parts® parts built as a direct-fit alternative to the original iRobot parts 4655986 / 4646124 / 4655987 / 4646490 / 4655988 / 4643682 / 4655989 / 4646123, and the kit includes two Dual Multi-Surface Rubber Brushes, two Corner Brushes, four high-efficiency filters and a cleaning tool – nine parts in all. The front caster and rollers collect hair from the s9’s tight reversing pattern, so the included cleaning tool pairs with the two fresh rollers to make the routine one-to-two-week clean fast, while the filters keep the motor breathing freely.
The rubber compound resists hardening to keep carpet grip, the Corner Brushes hold their sweep into tight angles, and the filters trap fines rather than recirculating them. If the s9550 SKU has you unsure which set to choose, the VacuumReviews.eu team will match it to your machine first.
