Introduction
The Roborock Qrevo Edge 2 and Roborock Qrevo Edge 2 Flow are two high-end models in Roborock’s 2026 product range. Both feature a comprehensive multifunctional dock, laser navigation and advanced artificial intelligence systems, although they differ significantly in their approach to mopping and mechanical configuration.
The Qrevo Edge 2 uses a traditional system with two rotating mop pads that can be automatically removed at the dock, while the Qrevo Edge 2 Flow features a 270 mm roller that radically changes how wet cleaning is performed. These technical differences create distinct user profiles that are worth examining in detail.
Suction power and vacuuming
The difference in power is significant. With 35,000 Pa, the Qrevo Edge 2 Flow exceeds the Qrevo Edge 2 by 10,000 Pa, providing a greater ability to extract embedded dirt from carpets or tile joints. This advantage is particularly noticeable in homes with pets or high-pile carpets.
Both models feature Roborock’s DuoDivide anti-tangle brush, which pushes hair towards the central opening to make it easier to collect and reduce tangles. Both can lift this main brush while mopping, preventing it from becoming unnecessarily wet.
The side-brush configuration marks another important difference. The Qrevo Edge 2 has an extendable side brush that improves sweeping in corners, while the Qrevo Edge 2 Flow uses a reversible side brush that can also be lifted while mopping. This lifting action prevents the brush from dragging dirty water across areas that have already been cleaned. Both feature anti-tangle technology on the side brush.
Mopping
This is where we find the most notable difference between the two robot vacuum cleaners. The Qrevo Edge 2 uses two rotating mop pads spinning at 230 RPM and applying 8 N of pressure, a proven and effective system for household mopping. The Qrevo Edge 2 Flow takes a completely different approach with a 270 mm roller that spins at 240 RPM and applies 15 N of pressure, almost twice as much as traditional mop pads.
The roller provides a larger surface area in continuous contact with the floor and more uniform pressure, which in practice may result in better removal of stuck-on dirt. Both models extend their mopping systems to reach edges more effectively.
The lifting height also differs: 12 mm on the Qrevo Edge 2 compared with 15 mm on the Qrevo Edge 2 Flow, which can also cover the roller completely. This additional capability is useful in homes with medium-pile carpets, although neither model is designed for thick carpets.
The warm water used by the Qrevo Edge 2 helps dissolve grease and stuck-on dirt more effectively while mopping the floor, providing an advantage over the cold water used by the Qrevo Edge 2 Flow. However, the latter compensates with greater mopping pressure.
An exclusive Qrevo Edge 2 feature is the automatic removal of its mop pads at the dock, enabling vacuum-only cleaning sessions without the mop pads touching the floor. The Qrevo Edge 2 Flow cannot do this due to its integrated roller configuration.
Both detect dirt on the mop pads or roller and the floor, automatically adjusting repeat cleaning in areas that require it.
Navigation system
Both models share the same navigation technology: retractable 360° LiDAR, an AI-powered RGB camera and a front 3D laser sensor with structured light. They recognise up to 280 different types of obstacles and can identify pets to adapt their behaviour.
Both can clean behind curtains and provide remote camera access, an LED for night vision and Roborock’s SmartPlan 3.0 system. They also use AI to detect stains and automatically adjust cleaning according to the type of dirt identified.
Runtime and battery
Both robots feature a 5,200 mAh battery. The Qrevo Edge 2 specifies a runtime of 188 minutes, while no figure is provided for the Qrevo Edge 2 Flow despite having the same battery capacity. Neither includes fast charging.
With this capacity, both models can cover medium-sized and large homes in a single session, particularly when vacuuming. Mopping reduces runtime because the robots must periodically return to the dock to wash the mop pads or roller.
Smart features
Both models can cross obstacles measuring up to 20 mm in height, which is sufficient for most door thresholds and small changes in floor level. Both include their own built-in voice assistant, compatibility with Alexa and Google Home and support for the Matter protocol.
Multifunctional cleaning dock
Both docks automatically empty the onboard dustbin and wash and dry the mop pads or roller with hot air. The dust bag has a capacity of 2.7 litres in both cases, while the clean-water tanks hold 4 litres.
Mop washing reaches 80°C on the Qrevo Edge 2 and 75°C on the Qrevo Edge 2 Flow, temperatures that are more than sufficient to disinfect and remove grease. Drying temperatures vary: 55°C on the former and 63°C on the latter, although both ensure complete drying and prevent unpleasant odours.
One practical difference concerns the washing tray. The Qrevo Edge 2 includes an automated 2.0 self-cleaning system, while the Qrevo Edge 2 Flow has a removable tray that makes manual cleaning easier but requires user intervention.
The dirty-water tank is slightly larger on the Qrevo Edge 2 at 3.5 litres compared with 3 litres, a minor difference with little impact on daily use.
Dimensions
Height represents a significant difference. At 79.8 mm, the Qrevo Edge 2 can clean underneath low furniture and beds that the 89.8 mm Qrevo Edge 2 Flow cannot reach. This 10 mm difference can be decisive in homes with low-clearance furniture.
The diameter is virtually identical: 352 mm compared with 353 mm. The docks have different configurations: the Qrevo Edge 2 dock is narrower at 340 mm but taller at 521 mm, while the Qrevo Edge 2 Flow dock is wider at 402 mm and shorter at 451 mm. It is advisable to measure the available space before deciding, particularly if the dock will be installed in a recess or underneath a piece of furniture.
Real-world user experience
For homes with limited clearance beneath furniture, the Qrevo Edge 2 offers a clear advantage due to its lower height. It can clean underneath sofas, beds and cabinets that the Qrevo Edge 2 Flow cannot access.
In homes with pets, the Qrevo Edge 2 Flow’s greater power of 35,000 Pa removes embedded hair from carpets and upholstery more effectively. Both feature the DuoDivide anti-tangle brush, but the additional power makes a difference when dealing with large quantities of hair.
For intensive mopping of hard floors, the Qrevo Edge 2 Flow’s roller, with 15 N of pressure and a larger contact surface, may deliver better results on stuck-on dirt. The Qrevo Edge 2’s warm water partially compensates for this difference, particularly when dealing with grease.
The ability to automatically remove the mop pads makes the Qrevo Edge 2 the better option for users who frequently alternate between vacuum-only cleaning and full mopping. The Qrevo Edge 2 Flow requires manual intervention to remove the roller if vacuuming without mopping is desired.
The Qrevo Edge 2 Flow’s liftable side brush prevents dirty water from being dragged across the floor while mopping, a detail that improves the final result in homes with complex room layouts.
Conclusion: which should you choose?
Choose the Roborock Qrevo Edge 2 if: you need the robot to clean underneath low furniture, where its height of 79.8 mm is a key advantage; you value warm-water mopping to dissolve grease more effectively; you want the mop pads to be removed automatically for vacuum-only sessions; or you prefer a narrower dock that occupies less width. It is also suitable if you want a proven and reliable traditional mopping system with rotating mop pads.
Choose the Roborock Qrevo Edge 2 Flow if: you prioritise maximum suction power of 35,000 Pa for carpets and pet hair; you want a roller mopping system that applies greater pressure of 15 N and provides a continuous contact surface; you need the side brush to lift while mopping to prevent it from dragging dirt; or you have space for a wider but shorter dock. The 270 mm roller can make a difference on heavily soiled floors or stuck-on stains.
