iRobot Roomba i4 – Plus.Parts® Replacement Dust Bags

The iRobot Roomba i4 is the standalone upper-mid i-series robot, sold without the Clean Base dock and suited to owners who prefer to add the dock separately. When an i4 is paired with a Clean Base, the dock handles the emptying step automatically at the end of each cleaning run, accumulating the bin’s contents into a sealed internal bag. The bag builds through up to thirty auto-emptying cycles before the dock sensor registers it as full and prompts a replacement, a cycle that on a daily cleaning schedule represents around four to six weeks between bag changes.

This three-bag replacement pack contains Plus.Parts® bags confirmed for the iRobot Clean Base dock used with the i4. Each bag matches the dock’s loading port opening and closure tab dimensions, loading with the same action as the iRobot original without requiring tools or adjustments. Ordering three at once provides the full supply needed to move through several bag changes without a reorder gap between each.

Performance at the disposal step is the key quality point for this bag. A replacement bag that loses seal integrity as it fills defeats the purpose of the sealed-closure design. This bag’s closure is built to engage reliably when the bag is at maximum capacity, not just when it is freshly installed, keeping the disposal step clean regardless of fill level. The VacuumReviews.eu team is available for compatibility questions about your specific i4 Clean Base dock model.

The recap
