Roborock S8 Pro Ultra – Plus.Parts® Spare Dust Bags

The Roborock S8 Pro Ultra advances the S-series with 6,000 Pa suction, the DuoRoller dual counter-rotating brush system, and the RockDock Ultra dock. The DuoRoller replaces the single all-rubber brush of earlier S-series models with two counter-rotating rubber rollers separated by a central divider, splitting long hair and fibres between the two rolls rather than concentrating them at one point. The RockDock Ultra handles auto-emptying with a sealed dustbag, mop washing with clean water, and mop drying with warm air, removing the need to touch the mop pad between sessions in most household routines. At 6,000 Pa, the S8 Pro Ultra moves more air per session than the S7 MaxV generation, which loads the dock station’s bag at a higher rate than lower-suction predecessors. The auto-empty mechanism pulls debris from the robot’s dustbin into the sealed bag at each dock return; a bag that is full or poorly seated interrupts this transfer and causes debris to accumulate in the robot’s bin rather than the station. Keeping the bag supply current prevents that build-up and keeps the hands-free routine intact.

This pack contains Plus.Parts® dust bags sized and sealed for the S8 Pro Ultra RockDock Ultra station. They fit and lock identically to the original Roborock bags, providing the same sealed containment the station was designed for. Twenty bags covers several months of daily auto-empty cycles in a typical household without a mid-supply reorder.

Each bag seals securely on removal to limit debris exposure during the change. The VacuumReviews.eu team handles any S8 Pro Ultra compatibility question personally and is reachable after purchase.
