Roborock Saros 20 vs Qrevo: Qrevo wins on carpet cleaning despite same suction spec

Both claim 10,000 Pa, but the Qrevo’s newer brush design and more aggressive suction curve actually pull more from carpet fibers and pet hair. The Saros 20 is no slouch, but the Qrevo feels tuned for messy jobs — that extra aggressiveness matters for embedded dirt, not just surface dust.
