Roborock's first roller-mop robot is a strong vacuum with excellent carpet protection — but the mopping falls short of roller-mop pioneers like Narwal and Ecovacs.
Roborock built the best carpet protection on any roller-mop robot and then forgot to make the mop actually clean well. The 15mm lift with a physical water-blocking guard is genuinely clever engineering — your carpet stays bone dry. And as a vacuum, the Curv 2 Flow is excellent: 20,000Pa, 0% hair tangle, 87% carpet deep-clean. But Vacuum Wars scored its mopping at just 25 points on dried stains versus a 112-point average across tested robots. That is not a rounding error; it is a fundamental weakness. At $849, you are competing with spinning-pad robots that mop circles around it, literally. Buy this if you want a premium vacuum with basic roller-mop maintenance cleaning. Do not buy it expecting Narwal Flow-level mopping performance.
