The Roborock R100042 is a regional configuration of Roborock’s auto-empty dock platform, the system that eliminates the need to manually empty the robot’s dustbin between sessions. Once the robot docks, the station activates for a few seconds, pulling collected debris into its sealed bag compartment through a pressure differential that clears the dustbin without spilling. For households with daily cleaning schedules and multiple rooms, this makes the difference between a vacuum that runs in the background of the day and one that requires regular interaction.
The dust bag is central to this process. It provides the sealed containment that keeps the auto-empty dock’s benefits intact: debris goes into the bag, stays there, and leaves the house when the bag is changed. This set of 20 Plus.Parts® dust bags is designed as a direct-fit replacement for the R100042 dock, matching the chamber dimensions and seal format of the original bags. The count of 20 means restocking is genuinely infrequent, which keeps the whole system in the background where it belongs.
Bag construction uses materials designed to hold through the suction cycle and through bag removal, with no loose seams or compromised edges that could allow debris to escape during disposal. Questions about compatibility or your order can be directed to our team, who handle them personally.
