Dreame RLX85CE replacement dust bags

The Dreame RLX85CE is the base model of the RLX85CE family, the platform reference from which the numbered hardware variants are derived for CE-market distribution. As the reference configuration, the RLX85CE establishes the auto-empty station format, bag compartment geometry, transfer fan specification, and maintenance guidelines that all numbered variants in the group share. For owners running the base RLX85CE, the bag replacement format and schedule are the originals on which all variant guidance is based.

The RLX85CE auto-empty station uses a suction fan to transfer debris from the robot’s cup to the installed bag after each docking event. The bag holds the accumulated debris until it is changed. Dreame recommends replacing the bag every 8 to 10 weeks under standard household conditions, with the station’s fill indicator providing the practical scheduling cue. A four-bag pack covers the full replacement cycle for approximately eight months in a normal-use household without requiring a mid-period reorder.

Maintaining the bag on schedule preserves the transfer performance that makes the auto-empty station useful. A bag that is allowed to overfill reduces transfer airflow, which can leave residual debris in the robot’s cup after docking events and cause fine dust to build up in the station’s inlet path over time. Regular changes, timed by the fill indicator rather than a fixed calendar, prevent both of these issues while extending the time between station-level maintenance tasks.

Because the RLX85CE is the base model of the range, parts confirmed for the base are confirmed for all numbered variants. This means that a four-bag pack purchased for the RLX85CE will also serve an RLX85CE-2, -3, -4, -5, or -6 if a household owns more than one variant or if a replacement is needed across variants within the family.

These bags are Plus.Parts® alternatives to the Dreame RDB7 / RDB8, both original OEM references for the RLX85CE bag format, with Dreame also cataloguing this part under number 20010100000840. Each bag is dimensioned to fit the RLX85CE station’s bag compartment and inlet without any modification. Install by opening the station front lid, withdrawing the old bag by its plastic tab (auto-seals on removal), inserting the new bag until the inlet engagement clicks, and closing the lid.

The four-layer construction provides more filtration stages than most standard alternatives available for this station format. Two layers of non-woven fabric form the outer wall of the bag and handle the coarser particle fraction. Two layers of melt-blown non-woven fabric form the inner wall and intercept fine particulate that passes through the outer non-woven layers. Keeping fine dust inside the bag during each transfer cycle reduces the accumulation rate on the station’s secondary filter, extending its effective service life between maintenance interventions.

All four bags in the pack are built with double hot-melted perimeter seams. The heat-bonding process fuses all four fabric layers at the edges, producing a seal that resists the suction force of the transfer fan and the weight load when the bag reaches its 3-litre capacity. The plastic tab is moulded from a hard-wearing grade that does not flex or crack through repeated removal cycles during the life of the pack.

The RLX85CE, as the base model of the range, is the reference point for compatibility confirmation across the full RLX85CE family. Our team is available to confirm compatibility for the base model and all numbered variants, and to assist with any question about your order from enquiry through to delivery and installation.
