The Roborock P20 Ultra Plus is a second-generation 18,500 Pa flagship, pairing a FlexiArm extending mop that reaches wall edges and furniture borders with a DuoDivide dual-roller brush and a Dock 3.0 station that washes mop pads at 75°C and empties the robot bin automatically at the end of each session. At 18,500 Pa the volume of fine material captured per run is substantially higher than on mid-tier models, and the dock dustbag fills at a corresponding rate. Under daily use the practical change interval sits at three to five weeks; leaving a full bag beyond that point causes the extraction cycle to stall mid-transfer, leaving the robot bin only partially cleared and reducing available bin capacity for the following run. Keeping a fresh bag rotation in place is one of the simpler ways to make sure the full automation loop runs without interruption.
This stock kit of 18 Plus.Parts® compatible bags covers the P20 Ultra Plus auto-empty station with a direct-fit option for the dock housing. The bags seal at extraction, containing debris and allergens through to disposal, and 18 in one order means monthly replacements are handled for well over a year from a single purchase. The bags fit the same housing geometry as the original Roborock consumables.
Materials and construction match the dock housing tolerances for a consistent seat and seal. Reach out to our team with any compatibility question or order query; we respond personally and sort it out.
