Roborock S91COP – Plus.Parts® Maintenance Set

The Roborock S91COP is a regional SKU variant of the Roborock Saros 10R, sharing every specification and all consumables with the S10R52-00 and the named Saros 10R. It navigates by structured-light sensors, optical cameras and AI obstacle recognition without a traditional lidar turret, operates at 20,000 Pa, and uses the DuoDivide dual-roller anti-tangle brush system alongside a Flexi-Arm extending side brush. The retractable flat mop module and 80°C dock wash-and-dry system are identical across all Saros 10R market SKUs. Every part in this maintenance set is fully interchangeable with those SKUs and fits the S91COP directly.

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. 20,000 Pa pulls far more air through the HEPA filter per session than mid-range robots; tap it out weekly and replace every two to three months before mid-grey discolouration causes the motor to compensate with extra current. The DuoDivide divider channel between the two rollers must be cleared at every service because a packed channel returns hair wrap to both rollers simultaneously – clear it and both end-cap sets before testing that each roller spins freely by hand. The Flexi-Arm rail needs a monthly wipe to maintain full extension travel. Replace dust bags every three to five weeks and inspect mop pads at eight weeks, replacing when texture or stiffness shows the dock wash cycle is no longer restoring cleaning performance.
