iRobot Roomba Combo R1118 – Plus.Parts® Replacement Filter Set

The iRobot Roomba Combo R1118 is a retail variant of the iRobot Roomba Combo, a combined vacuum-and-mop robot that integrates iRobot’s suction-based cleaning system with a mopping function for automated cleaning across hard floors. The R1118 uses iRobot’s systematic navigation to plan cleaning paths through rooms, drawing air through a high-efficiency filter in the exhaust path while the suction system operates. The filter captures fine dust and airborne particulate before exhaust air is returned to the room. Keeping the filter on a regular replacement schedule maintains the R1118’s airflow path and sustains suction at the designed performance level; an overdue filter restricts airflow and reduces the robot’s effective cleaning output.

This set of three Plus.Parts® high-efficiency replacement filters is a direct-fit option for the iRobot Roomba Combo R1118. Each filter is built to match the original filter’s dimensions and housing geometry, fitting the R1118’s filter slot without modification. Three per set covers three consecutive filter replacement intervals from a single order, providing a practical stock of replacement filters for ongoing maintenance on the Roomba Combo R1118.

High-efficiency filter media matched to the Roomba Combo R1118’s filtration specification. Our team covers the full iRobot Roomba Combo range and is available for any compatibility or order question.
