- The September 14 development is the US sales launch.
What changed
Roborock's Saros 20 Flow began its US market launch on September 14, according to Vacuum Wars. The company's US product page now offers purchase links. The vacuum-and-mop combination uses a roller that receives fresh water during cleaning, alongside a dock intended to automate routine maintenance.
Why it matters
US sales availability follows the earlier IFA preview. Continuous roller rinsing is designed to limit how much collected residue travels across a floor; results depend on the surface and mess. It is a useful design distinction, rather than a cleaning guarantee.
What remains unproven
Roborock qualifies its suction and threshold-crossing figures as results under specified test conditions. Vacuum Wars says its own evaluation is still pending. Neither the launch report nor this synthesis establishes long-term reliability or maintenance savings.
