iRobot Roomba Combo j7 – Plus.Parts® Rubber Brush Replacement Pair

The iRobot Roomba Combo j7 introduced a defining feature in the Combo range: a retractable mop arm that lifts the pad automatically when the robot detects carpet, allowing it to vacuum and mop within the same session without wetting carpet fibres. PrecisionVision navigation lets the j7 identify and route around common floor-level obstacles such as cables and pet waste, reducing mid-run interruptions. The vacuum performance relies on the dual rubber brush system, two rollers spinning inward that agitate carpet pile and sweep hard floor surfaces in the same pass. The rubber contact face of each roller determines how effectively debris is channelled toward the suction port, and because the two rollers work in opposition, the condition of both matters equally. When the rubber profile begins to flatten or stiffen on one roller, the system loses the inward-pull dynamic and debris is pushed sideways rather than collected.

This replacement pair is sourced by Plus.Parts® and contains two dual multi-surface rubber brushes matched to the Combo j7 brush module. The brushes drop into the same end-cap slots, the gear profile aligns with the drive, and the roller diameter and rubber thickness correspond to the original. Fitting a matched pair from the start means both rollers wear together through the next replacement cycle rather than one degrading ahead of the other.

The rubber in this set is formulated to stay flexible under the daily heat and friction that a regularly running Combo j7 generates. VacuumReviews.eu has reviewed the set for this model and the team is available for any question about a specific regional or retail variant.
