Eufy Omni S1 Pro vs Roborock Saros 20
The Roborock Saros 20 is the stronger cleaner on paper: 36,000 Pa suction versus 8,000 Pa, faster mop spin, and much better obstacle detection and threshold climbing. The Eufy Omni S1 Pro counters with a 3L water tank, a 2.5L dust bag and a 68-day self-empty cycle, so you touch it less often. Prices swing wildly on both, so check the current low before buying.
