iRobot Roomba s9558 – Plus.Parts® Filter Set

The iRobot Roomba s9558 belongs to iRobot’s premium s9 lineup, a series designed at the higher end of the robot vacuum market with a D-shaped body for corner cleaning, dual rubber AeroForce extractors that adapt to different floor surfaces, and a high-efficiency filter rated to capture particles down to 10 microns. The s9558 designation identifies a specific variant in the s9 family distributed in particular markets, running identical hardware to the core s9 platform. At this performance level, the filtration system carries significant load: the suction fan moves a high volume of air through the filter per session, and fine particulate from carpets, pet hair, and hard floor debris accumulates in the filter media at a corresponding rate. Replacing the filter before it restricts airflow is the straightforward maintenance step that keeps the s9558’s cleaning output at the level the machine is designed to deliver.

This three-filter set makes that maintenance straightforward. It contains Plus.Parts® high-efficiency filters designed as a direct-fit alternative to the original iRobot s9 series filter, matching the AeroForce housing dimensions exactly. Three filters in one pack covers the next two to three replacement cycles without additional orders, practical for any household running the s9558 on a regular cleaning schedule.

The filter media in each unit maintains its particle-capture performance across the full service period. We back every order with a team you can actually reach: compatibility questions, delivery concerns, or anything else handled personally.
