Roborock just introduced an innovative new robot vac mopping system — and it looks seriously good

• Roborock Saros 20 Sonic has a wide, flat mop pad that vibrates and applies downward pressure
• Uniquely, it can kick out to the side for complete coverage
• Pressure and water can be adjusted independently

The Saros 20 Sonic is one of a number of new Roborock robot vacuums I've been able to check out at CES 2026. It's an upgraded version of the popular Saros 10, and while it might not have the immediate wow-factor of the Rover, what has actual legs(!), it still made me do a double-take when I saw it in action.
