iRobot Roomba s9 – Plus.Parts® Replacement Filter

The iRobot Roomba s9 is the base model designation in iRobot’s premium s9 series, sharing the same D-shaped body, AeroForce three-stage cleaning system, and high-efficiency filtration as the s9150 and s9158 model number variants. The s9 was designed as iRobot’s highest-performance robot vacuum, combining dual rubber extractors that adapt to surface transitions, a high-efficiency filter rated at 99% particle capture down to 10 microns, and a suction fan delivering substantially more airflow than previous Roomba generations. The D-shaped chassis lets the robot clean flush against straight edges and reach into 90-degree corners, an area where round-bodied robots leave cleaning gaps. Maintaining the high-efficiency filter on schedule is a direct requirement for keeping the s9’s suction output at the level the AeroForce system was rated for; a loaded filter past its service limit reduces airflow and suction before the motor’s output is fully delivered to the floor surface.

This pack of three filters is a Plus.Parts® replacement set for the iRobot Roomba s9. Each filter is a direct-fit alternative to the original iRobot high-efficiency filter, matched to the s9’s filter housing for straightforward installation. Three filters in one order covers multiple maintenance intervals, a practical stock for a robot used in regular sessions across medium to large floor areas.

High-efficiency filter media matched to the Roomba s9’s AeroForce cleaning system specification. Our team is available for questions about compatibility with your specific s9 configuration or anything else in your order.
