Our Verdict

eufy Omni S2

Roborock Saros 20

The eufy Omni S2 and Roborock Saros 20 are both premium vacuum-and-mop combos with all-in-one docks, but the Saros 20 is the stronger overall performer. It picks up much more debris on hard floors and carpet, and it lifts far more pet hair. It also fits under much lower furniture, climbs taller thresholds, and requires less laborious upkeep. The Omni S2 makes more sense if you want a robot vacuum you can leave running unattended. It avoids obstacles far more reliably, and it steers around pet waste consistently, while the Saros 20 can't be trusted around accident-prone pets.
