iRobot Roomba 850 – Plus.Parts® Service Kit

The iRobot Roomba 850 is a core model in iRobot’s 800 generation, running AeroForce dual rubber extractors, the system that replaced the bristle-and-beater combination found in earlier Roomba lines. Two counter-rotating rubber cylinders pull debris up into a sealed channel rather than flinging it sideways, which is why the 850 handles long hair more cleanly than its predecessors and transitions from carpet to hard floor without a manual mode change. iAdapt IR navigation keeps the robot working in a directed sweep pattern, covering the cleaning area methodically.

Regular service on the 850 centres on three parts that wear independently. Rubber extractors are the highest-use components, the compound compresses on every stroke and gradually firms up until the robot starts to skim rather than grip. Side brushes feed edge and corner debris into the extractor path; their filaments shorten from use, and once they no longer reach the floor evenly, edge coverage drops. Filters trap fine particulate that would otherwise circulate back through the motor; a filter at cycle end restricts airflow and costs suction. This service kit contains Plus.Parts® components to address all three: rubber main brushes, 3 side brushes, and 3 filters, 8 direct-fit parts matched to the Roomba 850.

Every part fits the Roomba 850’s mounting points without cutting or adapters. The rubber compound holds its elasticity through the full cycle, and filter media is calibrated to the 800-series airflow requirements. Questions about your specific configuration or order are handled by a real person.
