iRobot Roomba i4 – Plus.Parts® Replacement Rubber Brush Pair

The iRobot Roomba i4 moves iRobot’s i-series up a step with improved navigation and a cleaning system that handles multi-surface environments without manual input. The AeroForce cleaning head uses dual counter-rotating rubber brushes that flex dynamically across both hard floors and carpets, capturing fine dust and larger particles while managing pet hair without tangling. The i4 supports iRobot’s Imprint Link technology for coordinated passes with compatible mopping robots and works with the Clean Base for hands-free bin emptying. Running on that kind of schedule, the brushes are in service constantly, and brush wear directly impacts how well the robot cleans.

The cleaning geometry of the AeroForce system depends on the brushes maintaining close contact with the floor across their full rotation. As the rubber softens with use, that contact changes, and the pick-up efficiency the i4 delivers on day one starts to deteriorate. Replacing the brushes at the right interval is the single most effective maintenance step for the platform. This set contains Plus.Parts® dual rubber brushes designed as a direct-fit alternative for the i4, both rollers match the cleaning head geometry and hub seating of the original components, and the rubber compound is formulated to replicate the original flex profile.

Materials are consistent across the production run, so you get the same performance from each replacement set. Our team is reachable for any compatibility question about the i4 range or for anything else about your order.
