The iRobot Roomba i1158 is an i1-tier Roomba that navigates using an optical floor-tracking sensor, an approach that produces structured, row-by-row cleaning without requiring the camera-based vSLAM mapping found in the upper i-series. The optical tracker monitors wheel encoder data to maintain position across each room, resulting in methodical passes that cover the floor area with less random-path repetition than bump-and-run models. The robot’s dual multi-surface rubber extractors work across hard floors and low-to-mid carpet simultaneously, pulling debris from surface and pile in each pass. The high-efficiency filter sits downstream in the airflow path, retaining fine dust before it can re-enter the room. Side brushes sweep corners and wall edges into the extraction path.
Regular use loads each of these components progressively: rubber extractors stiffen as the polymer compound ages, side brushes lose sweep coverage as the filaments wear, and filter media loads over time. This 9-part Plus.Parts® service kit, both rubber extractors, three edge-sweeping side brushes, three high-efficiency filters, and a cleaning tool, provides a complete replacement of every consumable category in one order, built as a direct-fit alternative to iRobot’s original i1158 service parts.
All parts are matched to the i1158 platform. Any question about compatibility or delivery is handled personally by our team.
