iRobot Roomba i7156 – Plus.Parts® Replacement Filter

The iRobot Roomba i7156 is a retail variant of iRobot’s Roomba i7, the model that sits at the top of the original i-series lineup. It combines Imprint Smart Mapping with a Clean Base-ready design, letting the robot learn multi-floor layouts and operate autonomously for weeks when paired with a self-emptying station. At that price tier, every component in the cleaning system is calibrated for performance: the AeroForce rubber extractors, the bin design, and the high-efficiency filter that sits between the bin and the exhaust. That filter handles the particles that are too fine for the extractors to push into the bin directly, the ones that travel in the airstream and end up in the room if the filter does not intercept them. A filter in good condition is an invisible but essential part of the i7’s performance promise; one past its effective life silently degrades that promise.

This pack contains three Plus.Parts® replacement filters, each matched to the Roomba i7156’s filter bay. The filter media is built to the high-efficiency standard the i7 requires, maintaining its particle-capture rate across the full replacement cycle rather than declining after the first month of use.

Each filter extends its life with dry-shake cleaning between replacements. Our team is reachable for any questions about fit or ordering and responds personally.
