The iRobot Roomba i3550 is a regional variant of iRobot’s i3 series, paired with a Clean Base Automatic Dirt Disposal dock that handles bin emptying automatically after each cleaning session. The Clean Base lifts debris from the robot’s onboard bin and seals it inside a bag installed in the dock, so the contents are contained and the robot is ready for its next scheduled run without any manual step from the owner. That auto-empty routine repeats with each session, and the bag fills gradually over time. Keeping spare bags on hand means the dock can continue emptying without interruption when the current bag reaches capacity.
These spare Plus.Parts® dust bags are matched for the iRobot Roomba i3550 Clean Base dock. Each pack contains 15 bags, giving more than a year of monthly replacements in a single order. The bags seal at the point of removal, keeping the bin contents contained throughout the monthly interval and making each disposal step clean.
Our team is available if you have a question about compatibility or need help with your order before it ships.
