The iRobot Roomba Plus 504 Vac is iRobot’s vacuum-only model within the Plus line: the robot handles suction and navigation, the AutoEmpty Dock handles waste collection, and together they run without requiring the user to empty the dustbin between sessions. The Plus 504 Vac pairs mid-range suction with the auto-empty convenience of the broader Plus family, and for households that want reliable daily cleaning without mopping, it sits in a practical position in iRobot’s lineup. The bag in the dock takes the full load of what the robot collects; for a vacuum-only model running daily, that means every debris type the robot encounters, fine dust, grit, pet hair, ends up in the bag rather than being distributed across multiple emptying steps.
This refill set of five bags is made for the Plus 504 Vac dock. Each is built from Plus.Parts® filtration-grade materials: a structured outer shell that holds its form under airflow and a media layer that captures fine particles rather than allowing them to pass back out as the dock draws the debris in. The bags fit the dock’s collection housing without modification, with the locking tab engaging the channel the same way as the originals.
Five bags in a single order covers most households for at least a few months. If you need a second pack or have questions about dock compatibility for a regional Plus 504 variant, reach out: we answer directly.
Your checklist
- Premium Materials – Filtration-grade outer shell and media selected for the Plus 504 Vac dock’s auto-empty conditions, where the bag must hold fine debris securely across multiple fill cycles.
- Built to Last – Structural shell and media bonded together to resist the airflow and fill pressure inside the dock’s collection chamber without deforming or losing its seal during use.
- Reliable Quality – All five bags produced to the same material and geometry specification, so the fit and filtration performance stays consistent across the full pack.
