The iRobot Roomba i4550 is a regional variant of iRobot’s i4 series, sold with a Clean Base Automatic Dirt Disposal dock. The Clean Base handles the bin-emptying step at the end of each session: it draws the robot’s contents into a sealed bag inside the dock, so the debris stays contained between bag changes and the robot is ready for its next run without any manual intervention. The bag accumulates debris with each auto-empty event until it reaches capacity, at which point it should be swapped for a fresh one. Keeping spare bags on hand ensures the dock is always able to complete the emptying cycle when the robot finishes cleaning.
These spare Plus.Parts® dust bags cover the iRobot Roomba i4550 Clean Base dock with 15 replacement bags per order. That is a practical quantity for more than a year of monthly replacements in one purchase. Each bag seals at removal, keeping the bin contents contained throughout the monthly interval and making each disposal step quick and clean.
