The Roborock S8 Pro Ultra brings the S8 generation’s key upgrades together in the flagship package: 6,000 Pa suction, a dual-brush system with a rubber main brush and a secondary roller for carpet agitation, and ReactiveAI 2.0 obstacle avoidance that handles cables, socks, and pet toys reliably. The dock matches the robot’s capability: it auto-empties the dustbin into a sealed bag, washes and dries the mop pad, and refills the water tank between sessions. The S8 Pro Ultra’s stronger suction and dual-brush pickup means more debris per session lands in the dock bag, and the bag reaches capacity in fewer runs than it might on a lighter machine. Swapping a full bag before the dock cycle fails is the one regular task the system still leaves to you.
These 4 replacement dust bags are Plus.Parts® components, recommended by VacuumReviews.eu for the Roborock S8 Pro Ultra dock. Each bag fits the dock’s collection chamber directly and seals on removal, keeping the dust contained through disposal. The material is matched to the S8 Pro Ultra dock’s collection volume, maintaining seal integrity and bag shape across a full fill cycle.
