The iRobot Roomba i1156’s cleaning relies on contact before suction. The dual rubber brushes, two contra-rotating rollers mounted across the intake, make direct contact with the floor surface and move debris toward the vacuum inlet. When the rubber compound wears, that contact becomes inconsistent: the rollers ride slightly above the floor rather than pressing against it. Suction alone cannot bridge that gap. In households with hard floors, the result appears first as a layer of fine dust that the robot crosses without collecting. On carpet it shows as reduced pickup depth, particularly in denser pile where direct brush pressure is what loosens embedded debris.
Replacing both brushes restores the full intake geometry. This set contains Plus.Parts® rubber brushes matched to the iRobot Roomba i1156 mounting points, installed the same way as the originals. No adapters, no tools, the same snap-in process iRobot designed for the platform.
