iRobot Roomba i3550 – Plus.Parts® Rubber Brush Replacement

The iRobot Roomba i3550 sits in the mid-tier of iRobot’s i-series, combining the AeroForce dual rubber brush system with Wi-Fi connectivity and app-based scheduling in an accessible package. The counter-rotating rubber rollers handle fine dust, larger debris, and pet hair across both hard floors and carpet without the bristle-tangle issues that older brush designs introduced. For a robot covering mixed surfaces daily, the brushes are the mechanical centre of every cleaning pass, and gradual wear on those rollers is something every i3550 owner encounters.

As brushes log hundreds of cleaning hours, their rubber gradually softens and the flex profile that maintains close contact with the floor shifts. The result is debris riding over the roller instead of being captured, and what used to take one pass now takes two or three. This set contains Plus.Parts® dual rubber brushes designed as a direct-fit alternative for the i3550, two rollers that install into the cleaning head and hub exactly like the originals, restoring the contact geometry the AeroForce system depends on.

The rubber compound is engineered to maintain flexibility throughout the full service interval, resisting the hardening that shorter-lived alternatives show within a few months. Our team knows the iRobot range well and is reachable directly for any compatibility question or order issue.

Quick take

• Long-Lasting Components – These brushes use a rubber compound formulated to hold its flex profile across the full replacement cycle, not just the initial weeks of use.
• Direct-Fit Compatibility – Both rollers match the i3550’s cleaning head geometry and hub fittings exactly, so installation is identical to swapping in the original parts.
• Responsive Support – A real team with hands-on iRobot maintenance knowledge is reachable for any compatibility question or anything else about your order.
