iRobot Roomba i1158 – Plus.Parts® Replacement Filter Kit

The iRobot Roomba i1158 is part of iRobot’s mid-range i-series, pairing dual rubber brushes with methodical navigation to cover a home room by room with minimal input. It handles a mix of hard floors and carpet in a single run, pulling dust, pet hair, and fine particles into the bin. That suction passes through the high-efficiency filter before the air is exhausted, and the filter is what keeps that exhaust clean. A fresh filter holds airflow open; a clogged one restricts suction from the motor and allows finer particles to pass through. The filter is the part of the i1158 that earns its replacement interval most quietly, until the day it makes itself known through reduced performance.

This kit contains three Plus.Parts® high-efficiency filters built as a direct-fit alternative to the original iRobot filter. Three in the pack means you can swap on schedule and keep the next one ready without reordering between each replacement. Fitting is straightforward: open the bin, lift the old filter out, press the new one in until it seats.

The filter media is manufactured to a denser specification than the generic alternatives at budget price points, holding filtration efficiency across the full replacement cycle. If you have a question about compatibility with your i1158 variant, our team answers personally.
