The auto-empty base station on the Dreame X40 Pro Ultra works on a straightforward principle: after each cleaning run, the robot docks and the station pulls collected debris from the onboard bin into a sealed dust bag. That cycle repeats daily, and over weeks the bag fills. When capacity is reached or the filtration layers degrade from accumulated fine particles, the transfer becomes less effective and the robot heads into its next session with a partially full bin.
This twenty-pack of Plus.Parts® dust bags provides a long-term supply for the X40 Pro Ultra base station, replacing the original Dreame bags with a four-layer filtration design. Non-woven and melt-blown layers work together to capture fine particles that simpler bags miss, while heat-sealed double edges and an auto-seal mechanism maintain the same construction quality across all twenty bags.
Every bag in a twenty-pack carries the same construction standard as the first: consistent filtration layers, sealed edges, and a pull tab that holds through weeks of use. If anything about your order or model compatibility needs attention, our team is here and responds personally.
