iRobot Roomba 870 – Plus.Parts® Replacement Parts Set

The iRobot Roomba 870 brought AeroForce dual rubber extractors into the mid-consumer tier of iRobot’s lineup. Where the 600-series bristle brush required manual removal to clear tangled hair, sometimes every session in a home with shedding pets, the rubber extractors on the 870 handle the same load with far less intervention. The counter-rotating cylinders pull hair and debris through a sealed channel without bristle tufts for fibers to catch in, so cleaning output stays more consistent between maintenance stops. Hard floors and carpet both feed into the same mechanism, and the 870 transitions between surface types mid-run without adjustment.

Airflow drives the system, and all three consumables affect it differently. Rubber extractors contact the floor directly on every stroke, over months the compound firms up and the robot begins to skim over surface debris rather than pulling it in. Side brushes extend the robot’s effective width to edges and corners; as filaments shorten, that reach shrinks and edge debris stays behind. Filters trap fine particulate carried through the motor path; a filter past its point restricts that path and suction drops noticeably. This care set contains Plus.Parts® components to address all three at once: rubber main brushes, 3 side brushes, and 3 filters, 8 compatible parts for the Roomba 870.

Rubber compound in this set holds its surface flex for the full replacement interval. The filters are matched to the 800-series airflow specification. Compatibility questions about the 870’s variant or order queries are handled directly by a real team member.
