The iRobot Roomba i3150 is a numeric variant of the Roomba i3, positioned in the mid range of iRobot’s i series. Navigation uses iAdapt 2.0, tracking floor movement optically to map the robot’s cleaning area and improve route coverage across sessions. The cleaning platform is the shared Roomba design: dual multi-surface rubber extractors, a high-efficiency filter, and an edge-sweeping side brush. The extractors flex across hard floors and carpet to channel debris into the bin. Over months of regular use, the rubber compound hardens and this flexibility is lost. The filter fills with fine particulate progressively, restricting the airflow the motor is sized to run at. The side brush loses its outward arc as its bristles flatten with use. Keeping all three on a consistent replacement schedule is how the i3150’s cleaning performance stays matched to its navigation capability.
This replenishment kit contains Plus.Parts® components matched to the iRobot Roomba i3150: a set of main rubber brushes, three side brushes, three filters, and a cleaning tool, nine parts covering every scheduled replacement interval. Each component is sized to the robot’s extractor bay and filter housing, fitting the standard mounting points without modification. The filter media is denser than generic aftermarket alternatives, maintaining the airflow the motor depends on through the full replacement cycle. The rubber brush compound stays flexible through the service period, keeping the extractors channelling effectively rather than hardening ahead of schedule.
