Follow ZDNET: Add us as a preferred source for the past month, which introduces the SpiralFlow mopping feature to the market. This robot vacuum and mop performs like a flagship device, with 20,000Pa of suction, a self-washing roller mop, and even a shield that covers the mop when the robot goes over carpet.

If you’ve used vacuum-and-mop combination robots, you’re familiar with the mop feature’s shortcomings. This is true whether they have a single mop pad, rotating pads, or self-washing features. Aside from the hands-free dock, the roller mop has been the biggest innovation in the robot vacuum market in recent years, making a huge difference in robot performance.
The Roborock Qrevo Curv 2 Flow, however, has a roller mop that continuously sprays clean water from a water tank inside the robot. At the same time, a scraper cleans the roller to remove dirty water, which is then kept in a separate wastewater tank in the robot.

This isn’t the first roller mop on the market — I’ve been testing this type of mop since 2024. But the Qrevo Curv 2 Flow is Roborock’s first dive into the roller mop system, and it’s a good one. As a leader in the robot vacuum market, this is a strong hint that Roborock is keeping up with the times, unlike other brands.
The Roborock Qrevo Curv 2 Flow’s mop roller is one of the best — if not the best– I’ve tested so far. It features 15N of downward pressure, which is over 3lbs to remove spills and stains; the same as the new Eufy Omni S2. The Curv 2’s roller mop is also 1cm longer than the new Ecovacs Deebot X12, which was just announced at CES 2026
