Roborock Qrevo Curv 2 Flow

A worthwhile mop change, with a height penalty

Qrevo Curv 2 Flow is the Roborock to consider when mopping the kitchen is the job you care about most. Fresh water feeds its roller while a scraper removes used water into a separate onboard tank. That gives it a practical distinction from spinning pads that carry dirt until the next dock wash: the cleaning surface is rinsed as it travels.

The compromise is easy to miss in the Curv name. Flow stands 119 mm tall, with a fixed navigation tower. The much lower CurvX can reach beneath furniture that stops this model. If your existing vacuum already struggles to get under the bed, buying Flow for a better mop will not solve that problem.

Roborock's German store offered Flow for €699 on September 11, 2026. At that price, the roller needs to be something you will use regularly: cheaper alternatives already cover ordinary vacuuming and automatic pad washing.

The roller is useful, but it is not a spill vacuum

Continuous rinsing makes sense for frequent kitchen and hallway cleaning. The roller extends toward edges, although Roborock's own FAQ allows a remaining gap of roughly 10 mm. Expect to clean the narrow strip beside a skirting board yourself when necessary; this is not a promise of perfect edge coverage.

The roller lifts 15 mm for carpet and a physical shield covers it. That is a thoughtful way to separate a wet cleaning surface from a rug, but it is different from removing the mop at the dock. The shield itself becomes another dirty part to maintain.

Do not buy Flow to collect puddles. Roborock explicitly excludes standing water and limits liquid spills in its guidance. Wipe up a substantial spill first, then let the robot handle routine residue. The advertised 75°C washing and 55°C drying happen at the dock, not on the floor.

For vacuuming, Flow uses the split DuoDivide brush and two side brushes. We have not measured its pickup or stain removal, so the 20,000 Pa specification is not evidence that it beats another robot on your rug. In a published German home test, Deskmodder found its Matter connection worked but also needed ramps for troublesome doorway transitions. That is a useful reminder to assess the floor plan: Flow lacks CurvX's lifting chassis.

Fresh water on the roller still leaves dirty water for you

The station empties dust, washes and dries the roller and refills the robot. There is no automatic detergent dosing. You add the recommended solution yourself and handle the water tanks, as well as cleaning the station's wash tray when needed.

The less obvious chore is on the robot: its used-water tank, channel and carpet shield need attention too. The manual shows these as serviceable parts, with screws involved in removing the shield. That is more ownership detail than a demonstration of a freshly rinsed roller tends to show. Buy it to reduce daily mopping, not to avoid cleaning wet equipment altogether.

Roborock calls for main-brush and filter cleaning every two weeks, side-brush cleaning monthly, and at least 24 hours of drying after washing the filter. Roller replacement is suggested every one to three months, depending on use. Leave space around the 450 mm cube dock to reach its tanks and wash tray without wrestling it out from under furniture.

Camera-based obstacle recognition, pet viewing and detailed maps live in Roborock's system. Released European Matter support has been demonstrated with Apple Home, making shared basic control a useful extra. It does not move the maps, camera or dock settings into one universal home app.

Compare two different reasons to spend less

Qrevo CurvX was €649 plus shipping from €5.99 at a German retailer during the same check. Choose it for its 79.8 mm lowered height and lifting chassis when furniture or doorways matter more than the roller.

Dreame Aqua10 Roller was €599 including German VAT and delivery. It also rinses a roller while cleaning, adds detergent dosing and lifting legs, and is similarly tall at 120 mm. That is a strong value alternative. Flow makes more sense when you prefer Roborock's app and its particular mop design enough to pay the extra €100.

Keep a working pad-based robot if your floors already look good with occasional manual mopping. A roller is a different cleaning mechanism, not an automatic reason to replace a machine that suits the house.
