Roborock Saros 20

Our Verdict: The most useful robot vacuum of the 2026 wave, precisely because it is not trying to climb stairs. Buy it for thresholds and suction.

The Saros 20 delivered the most practically useful advance of CES 2026. While the legged Saros Rover took the headlines, the Saros 20 is the one you can actually buy, and its chassis lift is the feature that changes daily use.

Roborock quotes a 3.46-inch double-layer lift from the AdaptiLift Chassis 3.0. That will not get it upstairs, but it clears the raised doorway strips, bathroom lips and thick rug edges that generate most stuck-again notifications. Paired with 36,000Pa from the HyperForce digital motor, it is the most capable conventional robot vacuum Roborock has shipped.
