iRobot Roomba i3 – Plus.Parts® Spare Dust Bags

The iRobot Roomba i3 is one of iRobot’s mid-entry i-series models, offering three-room mapping and more structured navigation than the base i1. When paired with a Clean Base dock, the i3 fits into an auto-empty routine where the dock lifts bin contents into a sealed bag after each session. The bag’s job is to hold everything that accumulates across those repeated emptying events: fine dust, debris, and anything the robot’s brush system picked up during the session. A bag that reaches capacity before it is replaced starts to affect how cleanly the dock empties, so keeping the replacement schedule is worth maintaining. Monthly changes work for most households running the robot a few times a week.

This pack contains 15 Plus.Parts® spare dust bags for the iRobot Roomba i3 Clean Base dock. The bags are sized to match the dock’s loading slot, and each one locks in place with the same tab mechanism as the original bags. At removal, the bag seals the contents inside, so disposal does not require handling the debris directly. Fifteen bags per pack means over a year of monthly replacements from a single order.

Our team is here for any question about your i3 dock or your order. We give direct, personal responses and work to sort things out without delay.
