The iRobot Roomba c9758 is a high-capability Combo model in iRobot’s c-series range, covering both vacuuming and mopping in each cleaning session. Like other c9-series robots, it uses a retractable mop system that prevents the mop pad from contacting carpet, and connects to a Clean Base auto-empty dock that handles the debris removal step automatically. The dock fills its internal bag over a series of cleaning sessions, typically thirty or more auto-emptying cycles, before the indicator signals a bag change is due.
Having a spare bag available at that point keeps the system running without pause. This pack supplies three Plus.Parts® replacement bags matched to the dock loading port on the Clean Base units compatible with the c9758. Each bag seats in the dock and engages the closure in the same way as the original iRobot bags, requiring no additional tools or adjustment.
The bag’s sealing mechanism is built to retain performance across the complete fill cycle. A bag at thirty cycles contains more compacted material than one just installed, and the closure is constructed to handle that load without loosening. The VacuumReviews.eu team can answer questions about which Clean Base dock generation this bag variant fits if you have more than one dock in use.
