A robot vacuum with an auto-empty dock is designed to reduce how often you think about cleaning. For the Dreame RLH31CE-BK, that works as long as the consumable at the heart of the system is doing its job. The dust bag inside the base station collects debris from every emptying cycle, and when it is full or its filtration layers have loaded with fine particles, the transfer efficiency drops.
These Plus.Parts® replacement dust bags are built for the RLH31CE-BK base station, fitting as a direct alternative to the original Dreame parts. The four-layer filtration structure uses melt-blown media for fine particle capture, with non-woven layers providing support. Double heat-sealed edges and an auto-seal removal mechanism complete the construction.
Quality does not vary across the four bags in this pack. If you need assistance confirming your model or anything else about your order, our team responds personally.
