Roborock Qrevo Curv – Plus.Parts® Replacement Parts Set

The Roborock Qrevo Curv is the first-generation flagship of the Qrevo 18,500 Pa tier and the only model in this maintenance set with the AdaptiLift chassis: a mechanism that raises the robot body to cross floor transitions up to 4 cm and lifts the mop pads to 17 mm when approaching the dock, allowing clean dock approach even when the pads carry moisture. The robot combines 18,500 Pa suction with the DuoDivide dual-roller anti-tangle brush, the FlexiArm dual spinning mop system that pushes pads outward for wall-edge coverage, and the FlexiArm side brush on an extending arc arm. Dock 3.0 washes both mop pads at 75 °C after every session and dries them with a warm-air cycle. The elevated suction fills the HEPA filter medium approximately three times faster than the entry Qrevo, reducing the effective replacement interval to around two months under daily use.

This set keeps the Qrevo Curv stocked with Plus.Parts® consumables built as a direct-fit alternative to the original Roborock part (also listed as 8020411 and HCTZ48RR): one DuoDivide brush set, four FlexiArm side brushes, four HEPA filters, four mop pads and four dock dust bags — seventeen parts in all. Remove both DuoDivide rollers every one to two weeks and clear the central divider channel at every service; the divider channel is the anti-tangle mechanism and a loaded channel wraps both rollers simultaneously, which looks like brush failure but resolves completely once the channel is clean. Inspect both end-cap bearing holes and replace the full brush set every five to seven months. Tap the HEPA filter firmly on all four frame edges every one to two weeks and replace it at two months; mid-grey colouration at this suction tier means the medium is close to full saturation and tap-cleaning recovers very little additional airflow. Supplied by Plus.Parts® as a direct-fit alternative to the original parts.
