Roborock QV 35S – Plus.Parts® Maintenance Set

The Roborock QV 35S is a regional SKU variant of the Qrevo L platform, sharing its 10,000 Pa suction motor, single DuoRoller main brush and dual spinning mop pads with every other model in this maintenance set. The dock runs a three-stage mop wash at a temperature below 75°C and finishes with warm-air drying, keeping limescale development slow compared with the hotter Dock 3.0 on higher-tier Qrevo models.

This set supplies Plus.Parts® direct-fit alternatives to the original Roborock parts MAINTENANCE SET: a rubber main roller brush, four anti-tangle side brushes, four washable filters, four dust bags and four mop pads – 17 parts in all. The DuoRoller brush is the part that rewards close attention on this platform. Hair coils into the narrow gap at both end-cap bearing housings, where it is invisible from above and builds compressive friction the motor has to fight. The first sign is a faint mechanical drag noise in the opening minutes of a run, before the bearings warm and the gap expands enough to mask it. Clear both end-cap holes with a toothpick at every weekly service and confirm the roll spins freely in both directions by hand before refitting. Replace the brush every five to seven months – every four to five with shedding pets – because once the bristle tips flatten past a certain point the brush pushes debris ahead rather than lifting it into the suction path.

Tap the HEPA filter edges over a bin every one to two weeks and replace every two months; the 10,000 Pa airflow loads the medium faster than on lower-suction Qrevo models. Never wash the pleated element – rinse only the pre-filter sponge if your model includes one. Clear the side-brush posts weekly and replace the set every three to six months. Inspect the mop pads at eight weeks and replace when the outer rim has lost its nap or discolouration persists after a dock wash. Replace the sealed dust bag every three to five weeks and empty the dirty-water tank every two to three days. Wipe the dock spray nozzle monthly to prevent limescale build-up, and clean the LDS lidar port and cliff sensors weekly with a dry cloth.
