iRobot Roomba Combo i8 – Plus.Parts® Rubber Brush Replacement

The iRobot Roomba Combo i8 occupies the higher end of the Roomba Combo range, combining stronger suction with the same dual rubber brush foundation that underpins the entire platform. Two counter-rotating rubber rollers pull debris upward from floor level, staying in contact with both carpet pile and hard floor texture through the flexibility of the rubber compound rather than the stiffness of a bristle core. The i8’s increased suction draws air through the brush housing at a higher rate, and that additional airflow also carries more heat through the roller area over each session. Combined with the friction of daily use across carpet and tile, this means the rubber compound on a well-used Combo i8 can reach the point of reduced flexibility before the brushes show any obvious visual wear. The consequence shows first in carpet pickup, where the brush’s ability to conform to pile depth determines how much debris reaches the suction port.

Replacing both rollers together addresses that directly. This set 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 for an installation that follows the same steps as the originals. The rubber compound is formulated to hold the flexibility needed for consistent multi-surface contact through a complete replacement interval.

Any question about compatibility or your order goes to a real person on the team; we respond directly, not through automated systems.
