Roborock finally brings a roller mop to its flagship robovac.

The company’s Saros 20 Flow goes on sale today for $1,499.99 (down from $1,699.99). At 3.53 inches tall, it’s one of the slimmest roller mop models, and with 36,000 Pa suction, camera-based obstacle recognition, and the ability to climb multi-layer thresholds, this robot should be able to get the job done. I got a first look at IFA last week and plan to test it soon.
