Introduction
The Roborock Qrevo Curv 2 Pro and the Roborock Qrevo Edge 2 represent two high-end offerings within the catalogue of the world's leading robot vacuum brand. Both units share the same 25,000 Pa suction power and the DuoDivide anti-tangle brush system, although they present significant differences in battery, navigation and base configuration that are worth analysing before deciding on one or the other.
The Qrevo Curv 2 Pro arrived on the market in 2025, whilst the Qrevo Edge 2 was launched in May 2026. These models are designed for demanding users seeking a complete cleaning solution with minimal manual intervention, especially useful in homes with different types of flooring and requirements for both vacuuming and deep mopping.
Power and Suction
Both models match their suction performance at 25,000 Pa, a figure that places these robots amongst the most powerful on the market. This power proves especially effective for medium-pile carpets and floors with ingrained dirt.
The DuoDivide anti-tangle main brush equips both models. This system pushes hairs towards the central gap for direct suction, considerably reducing tangles that typically occur with pets or long hair. Additionally, both robots can lift this brush during mopping, preventing it from wetting carpets.
As for the side brush, both incorporate an extendable and anti-tangle design, with the ability to reach corners better. Neither model lifts the side brush during mopping, although this doesn't pose a significant problem in daily use.
Mopping
The mopping system is based on two rotating mops in both cases, with side extension to better reach edges and skirting boards. The most relevant difference appears in water temperature: the Qrevo Edge 2 mops with warm water, which helps dissolve grease and stuck-on stains better, whilst the Curv 2 Pro uses cold water.
Mop lifting shows technical differences. The Curv 2 Pro offers a variable range of 7 to 17 mm, adapting better to different carpet heights. The Edge 2 maintains a fixed lift of 12 mm, sufficient for most domestic carpets but less versatile.
Both units automatically remove the mops at the base when you only need to vacuum, a practical function that avoids dragging unnecessary moisture. Dirt detection works on both the mops and the floor, allowing the robot to pass over particularly dirty areas again or wash the mops anew when it detects they're too soiled.
Navigation System
Retractable LiDAR equips both models, allowing the robot to hide under lower furniture by retracting the laser sensor when not needed. The AI camera reinforces navigation, although the Curv 2 Pro incorporates dual cameras compared to the Edge 2's single camera.
Obstacle recognition capability marks a notable difference: the Edge 2 identifies up to 280 different objects, whilst the Curv 2 Pro recognises 200. In homes with many objects on the floor or complex configurations, this greater Edge 2 capability translates into fewer manual interventions.
An exclusive Edge 2 function is curtain detection, preventing the robot from getting tangled in them during cleaning. The Curv 2 Pro doesn't include this feature. Both recognise pets, feature LED for night vision and allow remote camera access from the app.
Runtime and Battery
The Qrevo Curv 2 Pro's 6,400 mAh battery substantially exceeds the Edge 2's 5,200 mAh. This difference is directly reflected in runtime: 290 minutes versus 188 minutes. For large homes or those with multiple floors, the Curv 2 Pro offers greater margin before needing recharging.
In practice, 290 minutes allow cleaning more extensive surfaces in a single session without interruptions. The Edge 2, with its 188 minutes, proves sufficient for most flats and medium-sized houses, but may need intermediate recharges in spaces exceeding 150 square metres with intensive cleaning.
Smart Functions
The Qrevo Curv 2 Pro can overcome simple steps thanks to its terrain adaptation system, although the exact height specification isn't detailed. The Edge 2, however, clearly specifies its ability to overcome obstacles up to 20 mm, useful for transitions between rooms, thick carpets or small level changes.
Both models integrate their own voice assistant, in addition to compatibility with Alexa and Google Home. The SmartPlan 3.0 system manages intelligent cleaning in both cases, optimising routes and adapting power according to the detected floor type.
Multifunction Cleaning Base
The multifunction bases of both robots include auto-emptying of the dust bin, mop washing with hot water and drying with hot air. This configuration ensures the mops are always clean during mopping and dry upon finishing, preventing bad odours.
Wash tray self-cleaning presents different versions: 3.0 in the Curv 2 Pro and 2.0 in the Edge 2. Version 3.0 typically offers a more complete cleaning system of the tray itself where the mops are washed, reducing manual maintenance.
The dust bag reaches 2.5 litres in the Curv 2 Pro and 2.7 litres in the Edge 2, a minimal difference that barely affects replacement frequency. The clean water tank is identical at 4 litres, whilst the dirty water tank varies: 3 litres in the Curv 2 Pro and 3.5 litres in the Edge 2. Neither offers plumbing connection nor integrated detergent tank.
Dimensions
The robots share exact dimensions: 352 mm diameter and 79.8 mm height. This reduced height allows them to slide under most furniture, sofas and beds without problems.
The bases show significant differences. The Curv 2 Pro presents a cubic base of 450 mm in all its dimensions, occupying considerable floor space but with contained height. The Edge 2 opts for a narrower base of 340 mm width, although it reaches 521 mm in height and 487 mm in depth. In kitchens or reduced spaces, the Edge 2's base can better utilise narrow gaps, whilst the Curv 2 Pro's needs a more square area but not as tall.
Real-World Experience
For large homes, the Roborock Qrevo Curv 2 Pro proves more suitable thanks to its extended 290-minute runtime. It can complete full cleans in spacious areas without needing intermediate recharges, something especially useful in multi-storey houses or those exceeding 150 square metres.
The Edge 2 adapts better to flats and medium-sized houses where its 188-minute runtime proves sufficient. Its ability to recognise up to 280 obstacles makes it ideal for homes with many objects on the floor, toys or complex configurations. Curtain detection avoids problems in living rooms with long curtains.
In homes with pets, both work correctly thanks to the DuoDivide anti-tangle brush and 25,000 Pa power. The Edge 2's warm water mopping can make a difference in kitchens with grease or stuck-on stains, whilst the Curv 2 Pro's variable lift system adapts better to homes with different carpet heights.
Maintenance proves more convenient with the Curv 2 Pro due to its 3.0 tray self-cleaning system, reducing the frequency of manual base cleaning. The Edge 2 compensates with a slightly larger dirty water tank and better space management thanks to its narrower base.
Conclusion: Which to Choose?
Choose the Roborock Qrevo Curv 2 Pro if: You have a large home requiring extended runtime, prefer the more advanced tray self-cleaning system (3.0), need variable mop lifting for different carpet heights or have square space to position the base. It's the most complete option for spacious houses where runtime makes the difference.
Choose the Roborock Qrevo Edge 2 if: You live in a flat or medium-sized house, value warm water mopping for better results on grease and stains, need greater obstacle recognition capability (280 versus 200), have long curtains requiring specific detection or seek a narrower base that better utilises reduced spaces. Its ability to overcome 20 mm obstacles is clearly specified, which provides reassurance in homes with level changes.
