The Roborock S7 Max Ultra is built around the idea that the robot should manage its own maintenance between sessions. The full dock handles three jobs every time the robot returns: it empties the dustbin into a sealed bag, washes and dries the mop pad, and refills the water tank. The robot leaves the dock ready to work, no manual steps required. The VibraRise mop system lifts the pad clear of carpet automatically, so the robot can transition between wet mopping and dry vacuuming without stopping. The auto-empty function is the dustbin side of that complete automation. The bag inside the dock is the one consumable that requires attention: it fills over weeks of use and needs to be swapped before it reaches capacity, or the dock cannot complete the empty cycle on the robot’s next return.
These 4 dust bags are Plus.Parts® components, recommended by VacuumReviews.eu for the Roborock S7 Max Ultra dock. Each bag fits the dock’s collection chamber and seals on removal to keep dust contained. The construction is matched to the S7 Max Ultra dock’s collection function, maintaining bag integrity across the full fill cycle.
