iRobot Roomba i3 – Plus.Parts® Spare Parts Set

The iRobot Roomba i3 is the standard variant of iRobot’s optical-navigation mid-range, the same cleaning hardware as the i3+, without the Clean Base dock. iAdapt 2.0 tracks floor movement to build a working map of the home across cleaning sessions, improving route efficiency without relying on a front camera. The cleaning system is identical to the broader i-series platform: dual rubber extractors that press against carpet pile and hard floor surfaces equally, a high-efficiency filter that captures fine airborne particles, and a side brush for edges and corners. Each component follows a predictable wear cycle. Rubber extractors harden over time and start to slip past debris rather than channelling it; the filter loads progressively and begins restricting airflow; the side brush bristles bend outward and gradually reduce the robot’s corner-cleaning reach. Servicing them on the same schedule keeps the i3 performing at the level it does when parts are fresh.

This spare parts set contains Plus.Parts® components matched to the iRobot Roomba i3: a set of main rubber brushes, three side brushes, three filters, and a cleaning tool. Nine parts, every scheduled maintenance point covered in a single order. The components fit the robot’s extractor mounting system and filter bay exactly, so installation follows the same steps as the originals. The filter uses a tighter media weave than low-grade aftermarket alternatives, holding airflow through the full replacement interval. The rubber compound in the extractors resists the hardening that degrades cheaper alternatives over the first months of use.

There is a team ready to help with compatibility questions or anything about your order. We answer personally rather than routing through a ticketing system.
