Autonomy Intelligence Profile
Robot Autonomy Index methodology →The Roborock Saros 20 scores 96/100 on the Robot Autonomy Index (RAI), RobotSniper's 0–100 measure of how little human help a robot needs across navigation, obstacle avoidance, automation, and self-maintenance. That puts it in the Frontier-class tier — the most autonomous machines we track. Weeks of genuinely hands-off operation; best-in-class navigation, avoidance, and self-maintenance.

What does the Roborock Saros 20's Robot Autonomy Index (RAI) score of 96 mean?+

At 96/100, the Roborock Saros 20 is fully autonomous — the kind of robot you set up once and barely think about for weeks.

The Roborock Saros 20 pairs 36,000 Pa of suction with a dual-spin extendable mopping system, and carries a provisional obstacle-avoidance score of 96/100. Those published features make it a candidate for pet and mixed-floor homes, but the product evidence label should be checked before treating that as a tested conclusion.
How much maintenance does the Roborock Saros 20 need?+
