The Roborock QX Revo Ultra is a second-generation 18,500 Pa flagship built around a FlexiArm extending mop that pushes pad coverage into corners and along wall edges, a DuoDivide anti-tangle dual-roller brush, and a Dock 3.0 station that washes mop pads at 75°C and handles auto-empty automatically. The dock automation is designed to run after every cleaning session: the station draws debris from the robot bin and seals it inside a replaceable collection bag, so the bin is ready for the next cycle without manual intervention. The collection bag accumulates material at a rate reflecting the volume drawn per session at 18,500 Pa. Under daily use the practical change interval is three to five weeks; at the shorter end in heavier-use households. Keeping to that schedule ensures the station extraction cycle completes fully each time rather than stalling partway through.
This bundle of 18 Plus.Parts® compatible bags is matched to the QX Revo Ultra auto-empty station. The bags are sized to the dock housing for a direct fit, and each one seals at the moment of extraction to keep debris and fine particles contained from the first fill through to disposal. At 18 bags per purchase, monthly changes are covered for well over a year from a single order.
The bags are built to the station housing tolerances for a consistent seat on each install. Our team is available for any question about compatibility or your order, and we respond directly and personally.
