The short version
Key points
- The roller mop uses fresh water jets and continuous rinsing while it cleans.
- It lifted coffee, ketchup, mulberry and other sticky marks during testing.
- The robot combines 20,000Pa suction with dual anti-tangle brushes and side brushes.
- A roller shield lifts and protects rugs and carpets from the wet mop.
- The dock washes with hot water, dries with warm air and automatically empties dust and debris.
A roller mop designed for messy homes
The Qrevo Curv 2 Flow is Roborock’s newer roller-mopping robot, following the company’s dual-pad Curv model. Instead of dragging a flat mop pad across the floor, it uses a spinning microfiber roller. The roller rotates at up to 220 revolutions per minute and has eight water nozzles to distribute fresh water across its surface.
A scraper removes excess water so the roller remains damp rather than saturated. Dirty water is collected separately inside the robot as it cleans. This approach is intended to avoid simply spreading a spill across the floor, particularly in homes dealing with children, pets, sand and food marks.
Spill cleaning and dirt detection
The robot handled crushed mulberries, ketchup, coffee and other sticky mess during testing. Dry coffee stains were lifted impressively, while the robot could return to a particularly dirty area for another cleaning pass using its DirtTech dirt detection feature.
The system was not always efficient. On some occasions, it spent too long repeatedly cleaning one patch instead of moving on to the rest of the house. Camera-based features are off by default and require permission. The robot also works with the Roborock app and voice assistants including Alexa, Google and Apple services.
Carpet protection and edge cleaning
When moving from hard flooring to a rug or carpet, the mop roller lifts by approximately 14 millimetres. A shield also moves into place in front of the roller to help prevent moisture and dirt from reaching the carpet. During testing, the roller stayed clear of the rug as intended.
The mop can extend by about 4 centimetres and clean to within roughly 10 millimetres of an edge. Small side brushes help sweep debris towards the roller. However, like other round robot cleaners, it cannot fully reach every chair leg or the sharp corners of a square room.
Dock 4.0 and practical limitations
The Dock 4.0 station washes the roller with water up to 75 degrees Celsius, according to Roborock, and dries it with warm air around 55 degrees. During at least a week of use, the roller did not develop noticeable old-grime or mildew smells. The dock also auto-empties the dust bin. Roborock’s documentation states up to 65 days, although the testing suggested approximately 30 to 35 days in a home with a dog.
The dock still needs occasional maintenance, including cleaning its tray and emptying the relevant tanks. It is also large, occupying close to half a cubic metre, so installation space needs to be considered. The robot is relatively quiet in balanced mode at 60 to 63dB, but maximum suction is much louder. Roborock confirmed a two-year warranty for the Australian product.
TechManPat’s conclusion
I found the Roborock Qrevo Curv 2 Flow to be a benchmark device in this price range for automated mopping and vacuuming. I think it makes the most sense for people who genuinely want top-level convenience and see it discounted, rather than for anyone looking for a low-cost cleaner. At around $2,500, it is a substantial investment, but the roller mop, carpet protection and automated dock make it a compelling option for a particularly messy home.
