When the Dreame RTD31TE finishes a cleaning run, it docks and pushes everything it collected into a sealed dust bag. That bag handles the filtration, separating fine particles from the outgoing airflow so the dock’s internal pathway stays clean. Over eight to ten weeks the filtration layers load, and a fresh bag brings the transfer back to full efficiency.
These four Plus.Parts® bags replace the original parts in the Dreame RTD31TE dock. Each bag pairs two layers of melt-blown media with two non-woven layers for thorough particle capture across the full size range. Hot-melted double edges prevent splitting under the dock’s repeated compression, and the auto-seal engages on removal for clean disposal.
Build quality holds steady across all four bags. Our team is here if you need model confirmation or have any concern about your order.
