The Dreame L40 Ultra Gen2 cleaning system is designed to minimize the effort you put into floor maintenance. The robot handles the cleaning, the base station handles the emptying, and the dust bag inside stores everything until you decide to dispose of it. Replacing that bag when the filtration layers have loaded up is the simplest way to keep the whole system performing at its designed level.
This four-pack of Plus.Parts® dust bags fits the L40 Ultra Gen2 base station as a direct replacement for the original Dreame parts. Each bag uses four filtration layers with non-woven and melt-blown construction, sealed with heat-bonded edges that resist splitting under the suction pressure of the emptying cycle. The auto-seal mechanism keeps disposal clean every time.
Build quality holds across the entire pack. No variation in materials, no inconsistency in the edge seals. Our team is available if you have questions about compatibility or anything else about your order.
