The iRobot Roomba i4558 is a retail-channel variant of iRobot’s Roomba i4, built around the same Imprint Smart Mapping and AeroForce rubber extractor system as the rest of the i4 line. Its cleaning system is designed to handle a broad range of floor types in a single session, and the high-efficiency filter is central to that: it intercepts fine particles at the end of the cleaning chain so that what the robot collects stays collected. Filter media does degrade over time: the fibres compact, airflow drops, and the finest particles start slipping through. None of that is a malfunction. It is a predictable maintenance interval, and the right response is a straightforward filter replacement rather than a service call.
This pack contains three Plus.Parts® spare filters, each built to the dimensions of the Roomba i4558’s filter housing. The media density is matched to the high-efficiency standard the i-series requires, and each filter is designed to perform for the full expected interval before replacement.
Dry-shake the filter between sessions to clear surface dust and extend its working life. Our team answers questions about compatibility personally if you want to confirm your model before ordering.
