The iRobot Roomba x0858 operates on iRobot’s Roomba Combo platform, a robot architecture that integrates vacuum and mop functionality into a single device. In operation, the robot deploys its mop pad on hard floors and retracts it before transitioning to carpet, while the vacuum runs throughout each session. The high-efficiency filter in the exhaust path processes the airstream at every run, capturing fine dust and particulate matter that the dustbin alone would return to the room environment. Regular filter replacement is the primary maintenance task that preserves the x0858’s suction output and filtration efficiency at the level it was designed to deliver.
This four-pack of Plus.Parts® high-efficiency replacement filters is a direct-fit option for the iRobot Roomba x0858. Each filter is built to match the filter housing dimensions and installation geometry of the original component, fitting the x0858 without adjustment or modification. Four in one order provides coverage for four full service intervals from a single purchase, practical for a robot in regular daily use where maintaining the filter schedule consistently matters.
Filter media matched to the x0858’s airflow and suction specification. Our team covers the iRobot Combo platform and is available for any compatibility or order question.
