The iRobot Roomba w155240 is a catalog code designation for a specific regional or channel configuration of an AeroForce-generation iRobot Roomba. Model codes with the w-prefix identify particular market-specific variants within the AeroForce platform family; the underlying rubber brush extraction system is consistent across the range. The AeroForce head runs on two counter-rotating rubber rollers that flex against hard floors and carpet pile, drawing debris into the suction path through continuous direct contact. That flexible contact degrades with use: the rubber compound stiffens gradually over repeated cleaning cycles until the rollers produce audible scraping rather than quiet rolling, the sign that a replacement brush pair is needed to restore pick-up performance.
This replacement set is matched to the Roomba w155240’s AeroForce extraction head. It contains two Plus.Parts® rubber brushes in the counter-rotating format for AeroForce-generation models, using rubber compound formulated to hold pliability across the full replacement interval. Fitting them uses the standard AeroForce swap procedure: open the brush module, remove the worn rollers, seat the new pair, and close.
