Roborock P20 Ultra Plus – Plus.Parts® Maintenance Set

The Roborock P20 Ultra Plus is the P-series branded variant of the second-generation 18,500 Pa Qrevo flagship tier, sharing its architecture with the Qrevo Curv 2 Pro and Qrevo CurvX. It uses the DuoDivide dual-roller anti-tangle brush, a FlexiArm extending mop that pushes the pad outward for wall-edge mopping coverage, a FlexiArm side brush on an arc arm that swings out for skirting-board reach, and Dock 3.0 with 75°C mop washing.

This kit is a Plus.Parts® alternative to the original Roborock part, supplying 2 anti-tangle brush sets, 4 side brushes, 6 filters, 4 dust bags and 4 mop pads – 20 parts. At 18,500 Pa the HEPA filter loads roughly three times faster than on the original Qrevo and needs replacement every two months under daily residential use; tap it out weekly and replace on schedule rather than waiting for the visual grey cue. Clear the DuoDivide central divider channel at every brush service: a packed channel causes hair to wrap both rollers simultaneously rather than being intercepted, and the wrap will recur rapidly until the channel is clear. The FlexiArm side brush rail needs a monthly wipe; grit on the rail prevents full extension and leaves a dust strip along skirting boards even when the rest of the floor is clean. In hard-water areas, wipe the Dock 3.0 spray nozzle every two to three weeks because the 75°C wash temperature precipitates mineral scale faster than on cold-wash docks. Inspect mop pads at six weeks rather than eight on the FlexiArm mop because its extended travel arc concentrates wear at the outer edge of the pad.
