The iRobot Roomba Combo i8+ adds auto-empty functionality to the Roomba Combo i8 platform, running cleaning cycles and emptying into the dock without prompting. The dual rubber brush system is what determines how much debris reaches the dock on each return: two rubber rollers counter-rotate to pull material from hard floors and carpet, and their flexibility is what keeps surface contact consistent across both. A robot that docks and empties automatically can run for longer between manual brush checks, and that interval is part of why understanding how rubber brushes change over time matters with the i8+. Repeated heat from the higher-suction airflow and daily floor friction gradually stiffen the rubber compound. The rollers maintain their shape, but the subtle loss of flexibility reduces how well they conform to carpet pile and uneven hard floor surfaces, an effect that accumulates across months of daily auto-scheduled cleaning.
This replacement set resets both rollers at once. It contains Plus.Parts® components designed as a direct-fit alternative to the original iRobot Roomba Combo brushes, matched to the Combo i8+’s roller housing so the installation follows the same process as the originals. The rubber formulation is selected for the flexibility profile that keeps surface contact consistent through a full replacement interval.
