Roborock Qrevo Curv 2 Flow

Its SpiraFlow roller continuously washes the mop with fresh water, rotates at up to 220 rpm and applies up to 15 N of downward pressure. A scraper removes excess water and sends dirty water to a separate tank. The dock washes the roller with water up to 75°C and dries it with warm air up to 55°C.

The roller lifts up to 15 mm and the Roller Shield deploys a physical barrier against moisture and dirt. In the Roborock app, choose deeper carpet cleaning with the mop raised or set the robot to avoid rugs; carpet settings must be enabled and selected.

The vacuum provides up to 20,000 Pa of suction. Its Certified Dual Anti-Tangle System pairs a DuoDivide main brush with dual lifting arc side brushes to reduce tangles from hair and pet fur.

The Curv 2 Flow uses a continuously refreshed roller mop with up to 15 N pressure. The Curv 2 Pro uses dual rotating mop pads, with up to 60°C hot-water mop washing, 20 mm mop lift and up to 100°C dock self-cleaning.

It washes and dries the roller, empties dust and can extend washing or repeat mopping when it detects heavier dirt. The roller, scraper, wastewater tank and other key parts can be removed for cleaning.

Vacuum-and-mop operation is about 62–65 dB, dock operation about 56–57 dB, and dust emptying about 70 dB for less than a minute. It has a 5,200 mAh battery and takes about three hours to charge from 15% to full; runtime depends on cleaning mode and conditions.

It is a robot vacuum and mop, not a wet vacuum designed to collect standing liquid. For a large spill, wipe up more than about 50 ml first; the wastewater tank holds roughly 100 ml.
