The Roborock QX1PEC is part of the Q-series lineup, a family of robots built to run daily combining thorough vacuuming with a mopping pass in a single session. Like the rest of the Q-series, its rubber main brush was a deliberate departure from bristle rollers: the rubber fins create a more predictable floor-contact geometry that picks up fine debris and larger particles in one sweep without relying on bristle flex. That geometry depends on the compound staying pliable: rubber that has hardened or flattened from daily flexing no longer creates the suction seal the motor is tuned around, and pick-up drops across all surface types as a result.
This set covers the next two replacements with Plus.Parts® components built as a direct-fit alternative: 3 washable rubber main brushes matched to the QX1PEC roller housing dimensions. The compound specification is selected for daily-use durability, resisting the early hardening that shows up in cheaper alternatives after the first few months. No tools are needed for swapping: removal and reinstallation follow the same motion as the original factory brush.
