The U.S. launch adds a self-cleaning roller and automated dock, but pricing and independent results are still unclear.
Roborock launched the Saros 20 Flow in the United States on September 14, following its IFA 2026 preview in Berlin, Vacuum Wars reports. It starts selling today, but the reported launch information does not list a U.S. price, warranty terms or ongoing maintenance costs.
The biggest change is the SpiraFlow 2.0 mop. Instead of two rotating pads, the robot uses a roller that Roborock says receives clean water as it moves across the floor. The roller rotates at up to 240 revolutions per minute, supplied by 16 pressurized water outlets, and can extend toward walls and baseboards.
That could reduce residue transfer during longer mopping runs, though the source does not provide independent stain-cleaning results. The RockDock also aims to cut down on routine work: Roborock says it washes the roller with water heated to as much as 212°F, dries it with warm air, dispenses detergent, refills the robot with warm water and empties collected debris.
For homes with awkward layouts, Roborock claims the robot can cross double-layer thresholds totaling up to 3.46 inches. It lists the robot at about 3.54 inches tall and uses retractable LiDAR, which measures distance with light, to help it pass beneath some furniture.
Roborock also claims 36,000 pascals of suction and camera-based obstacle recognition for more than 300 household-object categories, including in lower light.
Vacuum Wars had not independently tested the Saros 20 Flow when it reported the launch. Buyers who want less mop maintenance should watch it, but waiting for independent cleaning, navigation and threshold tests—and a confirmed price—is the safer move.
