The iRobot Roomba y051040 is part of iRobot’s auto-empty robot range: a system where the cleaning work and the waste collection work are split across two components. The robot handles the floors; the base station handles the waste. After each cleaning run, the robot docks, and the station automatically draws the debris load from the robot’s dustbin into a bag in the base. The y051040 runs through this cycle reliably, and the dust bag is what makes hands-free operation practical over time: it is the final storage point for everything the robot collected. Replacing it before it is completely full keeps the dock’s airflow clear and the next emptying cycle as effective as the first.
Each bag in this five-pack is produced to the y051040 dock specification, made with Plus.Parts® filtration-grade bag material: a construction that emphasises media density over thin-wall economics. Generic bags often use a lighter media that lets fine particles pass back out under suction; these carry a tighter weave that holds them. The geometry matches the original iRobot bags, so the locking tab engages cleanly and the bag opens to the correct internal volume without distortion.
Five bags per pack covers most households for several months. If you need to check compatibility with a specific regional code, reach out and we will confirm before you order.
What matters
- Direct-Fit Compatibility – Each bag is shaped to the y051040 AutoEmpty Dock’s internal housing, engaging the locking mechanism the same way as the original iRobot bags.
- Designed for Daily Use – Made to handle the consistent fill cycles of a robot running daily in an active household, without seal degradation between the first and last use.
- Reliable Quality – Filtration-grade media that retains fine particles rather than venting them back through the bag surface under the dock’s suction cycle.
