Roborock R100042 – Plus.Parts® Dust Bag Value Pack

The Roborock R100042 is part of Roborock’s range of auto-empty docking stations, designed to pair with Q and S series robot vacuums. The dock handles debris collection automatically: when the robot finishes and returns to base, the station’s motor evacuates the robot’s dustbin into a sealed bag in the collection chamber. That automated loop is one of the more practical features in modern robot vacuum ownership: the robot and its dock handle the full cycle from cleaning to waste collection without requiring daily attention. The bag inside the collection chamber is the only part of that loop that needs periodic replacement. A bag that has reached capacity will still accept the robot but cannot collect additional debris efficiently. Checking the bag every few weeks and replacing it before it is completely full keeps the dock’s evacuation suction at consistent levels.

The four bags in this value pack are Plus.Parts® components, designed as a direct-fit alternative to the original Roborock dust bags for the R100042 dock. Each bag is formed to the collar and body dimensions of the dock’s collection chamber, installing without tools: just remove the spent bag and push the new one into the holder until the collar locks. Buying four at once reduces how often you need to reorder and keeps a buffer in stock for when the current bag reaches capacity.

The bag material is chosen to seal fine particles on collection, so the bag holds its contents without releasing dust during removal. Our team is available for compatibility questions or anything else about your order; reach out and we will respond directly.
