Roborock’s R100039 auto-empty dock takes one of the least pleasant parts of robot vacuum ownership, emptying the dustbin, and removes it from the routine entirely. The dock’s suction draws debris from the robot into a sealed bag in its collection chamber, and for most households a single bag will hold several weeks of daily cleaning before it needs changing. Over that period, the bag fills gradually with fine dust, hair, and debris. This is exactly what it is designed to do, and the dust bag is a straightforward consumable: when it is full, replace it with a fresh one and the system is back to full capacity immediately. Keeping a set of spares on hand means the replacement never requires a trip to the shops mid-routine.
This set of four Plus.Parts® dust bags is designed as a direct-fit alternative to the original Roborock collection bags for the R100039. The collar is formed to match the dock’s bag holder, and the body dimensions sit within the chamber without buckling or bunching. Buying four at once covers the typical replacement needs of most households for several months.
Each bag uses a fabric that traps particles on contact and seals at the neck, so removing a spent bag does not release dust back into the room. Questions about which bags fit your specific dock setup are welcome; our team responds to those personally and works to sort any issue quickly.
