iRobot Roomba i3158 – Plus.Parts® Filter Service Supply

The iRobot Roomba i3158 is a retailer-channel catalog variant of iRobot’s i3 platform, running the same dual rubber extractor cleaning system found across the i3 range. The extractors flex to engage carpet fibers and sweep hard floors efficiently in a single pass, and the row-by-row cleaning pattern covers the floor area methodically. The robot auto-adjusts between floor types and handles recharge-and-resume on longer sessions. The i3158 is built for everyday household cleaning with a maintenance routine focused on two manual tasks, emptying the bin and replacing the filter, both straightforward and completed without tools in the same upper compartment.

The high-efficiency filter sits in the airpath between the bin and the motor, capturing fine dust, allergens, and particulate matter that pass through the debris chamber. Each cleaning session adds to the filter’s load, and when capacity is reached, the increased airflow resistance translates into reduced suction across the cleaning surface. Replacing the filter on schedule keeps the robot running at its rated performance. This service supply contains three Plus.Parts® high-efficiency filters designed as direct-fit replacements for the i3158 housing, matching the original iRobot part dimensions so the swap is tool-free. Three units in a single order provide full coverage across consecutive service intervals.

Each filter is built to maintain consistent filtration and airflow performance throughout the full replacement cycle. Questions about fit with your i3158 or anything about the order are answered personally by the VacuumReviews.eu team.
