The Roborock S9 MaxV Ultra sits at the premium end of Roborock’s S9 lineup, combining high-output suction with front-facing camera-assisted obstacle detection and a fully featured dock that handles dustbin emptying, mop washing, and drying automatically. After each cleaning run the dock draws collected debris into a sealed bag, keeping the dustbin at full capacity for the next session. That level of automation puts most of the cleaning routine on the robot, and the bag is the one consumable that keeps the dock side of that cycle running without interruption.
This bulk pack contains Plus.Parts® dust bags, each cut to the S9 MaxV Ultra dock’s bay dimensions and sealed at removal for clean, contact-free disposal. Six bags are included, providing a supply buffer so you are never caught waiting on a replacement when the dock prompts a swap.
Materials and seal quality are built to handle the volume of fine dust and debris a high-output robot like the S9 MaxV Ultra collects across daily sessions. The VacuumReviews.eu team reviewed these bags against the original dock specification before recommending them. Reach out with any compatibility questions and we will answer directly.
