Roborock Saros 20 earns position #2 by matching strong robot-vacuum fundamentals with a clear buyer fit. Ranked second as the strongest Roborock flagship candidate: it has unusually broad threshold, low-furniture, support/manual, and full-dock coverage while staying focused on robot-vacuum fundamentals. In practical terms, that makes it best for premium homes with thresholds, pets, rugs, and low furniture rather than shoppers who simply want the cheapest or simplest robot available.
The upside is straightforward: strong threshold and low-clearance positioning, robust official support/manual coverage, premium dock and mop automation. The tradeoffs are just as important: flagship value tradeoff, owner data remains thin, small onboard bin may matter in heavy-pet homes. That balance is why it lands where it does instead of being treated as a one-size-fits-all winner.
Choose it if your home matches its strengths: premium homes with thresholds, pets, rugs, and low furniture, buyers wanting robust official support/manual availability. Skip it if your priorities look more like homes where value is more important than flagship features, heavy pet homes that may fill a small dustbin quickly.
