Overview

The Saros 20 family is Roborock's 2026 flagship line, shown at CES 2026 and sold in the US from March 23, 2026, with the Flow roller-mop version following in September. All three share 36,000 Pa suction, the AdaptiLift 3.0 chassis that climbs double thresholds up to 88 mm, and a dock that washes mops in boiling water and dries the dust bag. They differ in the mop (spinning pads, vibrating pad or roller) and in obstacle sensing. It replaces the Saros 10 and 10R, and the arm-equipped Saros Z70 sits alongside it.
