The iRobot Roomba i3558 is designed for mixed-floor households, using a dual rubber brush system that performs across hard floors and carpet pile without requiring separate modes or manual adjustments. The rollers counter-rotate to flex against the floor surface, lifting fine dust and larger debris while the rubber compound resists the hair tangling that bristle-brush designs struggle with in homes with pets. App-controlled and Wi-Fi connected, the i3558 is built to run on a schedule, and on that schedule, the brushes accumulate meaningful wear.
Rubber brushes do not fail suddenly. They wear gradually, and the first sign is usually that cleaning passes leave behind what they used to capture cleanly. The rollers lose their precise contact with the floor, and suction alone cannot compensate for debris that is not being mechanically lifted. This set contains Plus.Parts® replacement rollers engineered as a direct-fit alternative for the i3558, two brushes that seat into the cleaning head identically to the originals and restore the full pickup profile. The rubber formulation is selected to maintain its properties across the full replacement interval.
Quality control ensures both rollers meet the same dimensional tolerances as the originals before they leave the packaging. If you have any question about fitment on your specific i3558 or about your order, reach out to the team directly; we answer personally.
What matters
- Built to Last – The rubber compound is selected to maintain its flex properties across repeated use, avoiding the early hardening that shortens the service life of lower-quality alternatives.
- Inspected Before Shipping – Dimensional and material checks are carried out before dispatch to ensure both rollers are ready to install and perform from day one.
- Recommended by Our Team – The i3558 platform is familiar to the VacuumReviews.eu team, and this replacement set reflects what we know works on the AeroForce cleaning head.
