The iRobot Roomba Plus 405 Combo is iRobot’s mid-range entry into the combined vacuum-and-mop category, pairing automatic emptying with a mopping system in a single robot. When a cleaning session ends, the Plus 405 Combo returns to its AutoEmpty Dock, which draws the dustbin contents out of the robot and deposits them into a sealed bag inside the base. That process repeats session after session, hands-free, until the bag is full. For households with pets or high foot traffic, the bag can reach capacity in a few weeks; in quieter homes it lasts longer. Either way, replacing it promptly keeps the dock’s airflow clear and the robot’s next emptying cycle as effective as the first.
These five bags are a direct-fit replacement for the Plus 405 Combo’s dock. Each is made with Plus.Parts® filtration-grade bag media, a tighter construction than most generic aftermarket bags, designed to hold fine particles inside the bag as the dock pulls debris through under suction, rather than allowing them to vent back into the room air. The bags match the dock’s internal dimensions and locking tab geometry, so they seat and seal the same way as the originals.
