The iRobot Roomba i3558 is a retailer-channel configuration of iRobot’s i3+ platform, bringing dual rubber extractors and the Clean Base auto-empty dock together under a specific catalog code. The cleaning system covers the floor in structured rows, adapts suction to carpet and hard-floor surfaces automatically, and resumes after recharging on larger sessions. The Clean Base empties the bin after each run, keeping the robot ready for the next scheduled session without owner involvement. The i3558 represents the i3+ experience in a specific regional or retailer variant: the underlying platform and performance are consistent with the i3+ range.
The filter inside the i3558 handles the fine-particle side of the exhaust air stream, dust, pollen, allergens, and pet dander that collect in the filter media across every session. The Clean Base dock takes care of the debris bin, but the filter must still be replaced manually on a regular schedule. When the filter loads up beyond its effective capacity, airflow restriction through the motor builds and suction output falls. Staying ahead of the replacement interval is simpler than addressing the performance drop after the fact. This replenishment supply contains three Plus.Parts® high-efficiency filters matched to the i3558 housing dimensions for a tool-free direct-fit swap. Three units in a single order provides coverage across multiple consecutive service intervals.
Filter media quality is consistent across all three units so each replacement restores the same clean baseline to the motor airpath. Questions about compatibility with your specific i3558 unit or the order are answered personally by the VacuumReviews.eu team.
