The iRobot Roomba Combo i5+ adds an auto-empty dock to the Roomba Combo i5 platform, which changes the maintenance picture in a specific way: the robot empties its bin automatically, reducing the frequency of hands-on contact, but that also means the brushes can run longer between manual inspections. The dual rubber brush system is still the mechanism that determines how much debris makes it to the bin in the first place. Two rubber rollers counter-rotate to pull debris from hard floors and carpet, handling pet hair without the bristle-tangle maintenance overhead, and delivering it efficiently to the suction port. The flexible rubber surface that makes surface contact consistent across floor textures, and ensures the debris transfer to the dock is as complete as the robot’s design allows, is what changes with use. Repeated heat and friction cycles stiffen the compound gradually, and a slightly stiffer brush on a robot that auto-empties without prompting can go longer before the reduced pickup is noticed.
This spare set keeps the replacement schedule on track. It contains Plus.Parts® components designed as a direct-fit alternative to the original iRobot Roomba Combo brushes, matched to the Combo i5+’s roller housing for a straightforward installation. The rubber compound maintains its flexibility profile through a complete replacement interval.
