The iRobot Roomba c7156 is part of iRobot’s Roomba Combo c series, a platform that combines a vacuum system and a deployable mop pad in a single robot, cleaning both dry debris and surface grime in the same automated session. The mop pad retracts before the robot transitions onto carpet, and the vacuum runs continuously throughout. The high-efficiency filter sits in the exhaust path, capturing fine dust and particulate matter before the air returns to the room. Maintaining the filter on the recommended interval keeps the c7156’s suction output consistent with its designed performance level; a filter allowed to build up beyond its service interval restricts airflow and reduces the suction the motor can deliver.
This set of four Plus.Parts® high-efficiency replacement filters provides a direct-fit replacement option for the iRobot Roomba c7156. Each filter matches the housing dimensions and clip positions of the original iRobot filter and installs without modification. Four filters in one pack cover four consecutive maintenance intervals, reducing the number of reorder events for households where the robot runs on a regular schedule.
High-efficiency filter media suited to the c7156’s airflow specification. Our team covers the full iRobot Combo range and is available for any compatibility or order question.
