Introduction
The Roborock Qrevo Curv 2 Pro and the Roborock Qrevo Edge S5A represent two consecutive generations of Roborock's premium range, with the former launched in 2025 and the latter in 2024. Both units integrate a complete multifunctional base with mop washing and drying, along with the DuoDivide Anti-Tangle brush system that characterises the brand's premium models. The generational difference translates into substantial improvements in power, navigation and intelligent functions that are worth analysing to decide which model best suits each type of home.
These robots are designed for users seeking total automation of maintenance, with particular emphasis on mopping thanks to their bases that wash the mops with hot water and dry them with hot air. The choice between one and the other will depend on factors such as the complexity of the home, the presence of pets and the need for advanced recognition functions.
Power and Suction
The difference in suction power is significant. The Roborock Qrevo Curv 2 Pro reaches 25,000 Pa, whilst the Qrevo Edge S5A remains at 18,500 Pa. This gap of 6,500 Pa translates into greater capacity to extract embedded dirt from carpets and superior performance on surfaces with pet hair.
Both models incorporate the DuoDivide Anti-Tangle brush, a design that pushes hairs towards the central gap for direct suction, minimising tangles. The advantage of the 2025 model lies in the fact that this brush can be lifted during mopping, preventing it from getting unnecessarily wet and allowing more efficient mopping without dragging the brush across the wet floor.
Regarding the side sweeping system, both units feature an extendable and anti-tangle brush, which improves cleaning in corners and edges. This feature is especially useful in homes with skirting boards and hard-to-reach corners.
Mopping
The mopping system is based on two rotating mops in both cases, with extension to better reach edges. The main difference lies in the mop lift: the Qrevo Curv 2 Pro offers a variable range of 7 to 17 mm, whilst the Edge S5A maintains a fixed lift of 10 mm. This flexibility allows the more recent model to better adapt to different carpet heights and obstacles.
A notable function of the Qrevo Curv 2 Pro is the automatic removal of the mops at the base when only vacuuming is desired. This avoids having to manually handle the mops each time you want to alternate between cleaning modes, something the Edge S5A cannot do autonomously.
The bases of both robots wash the mops with hot water and dry them with hot air, guaranteeing hygiene and preventing bad odours. The Qrevo Curv 2 Pro incorporates the 3.0 tray self-cleaning system, an evolution from the 2.0 of the previous model, although in practice both systems effectively fulfil their function. Both units detect dirt on both the mops and the floor, adjusting the washing and scrubbing process as needed.
Navigation System
Here we find one of the most relevant differences. The Roborock Qrevo Curv 2 Pro features a retractable LiDAR system combined with dual AI camera, front 3D laser sensor and night vision LED. This configuration allows it to recognise up to 200 types of obstacles, including pets, and offers remote camera access for home surveillance.
The Qrevo Edge S5A, on the other hand, uses a LiDAR 3.0 turret without integrated camera. Although it has obstacle avoidance, it does not reach the level of detailed recognition of the later model nor can it specifically identify pets. It also lacks remote camera access or LED for night navigation.
In terms of artificial intelligence, the Curv 2 Pro integrates SmartPlan 3.0 with stain recognition, whilst the Edge S5A uses SmartPlan 2.0 without this specific function. The Edge S5A's processor is the RR Mason 11.0, but the most recent model's is not specified.
Runtime and Battery
The Roborock Qrevo Curv 2 Pro's battery has a capacity of 6,400 mAh which translates into 290 minutes of runtime. The Qrevo Edge S5A, with 5,200 mAh, offers 180 minutes. This difference of 110 minutes is decisive in large homes, where the 2025 model can complete cleaning in a single session whilst the previous one might need intermediate recharging.
For surfaces up to 150-200 m², the Edge S5A performs without problems. But in larger homes or with complex layouts that require longer navigation time, the extended runtime of the Qrevo Curv 2 Pro makes the difference between smooth cleaning and interrupted cleaning.
Intelligent Functions
The Roborock Qrevo Curv 2 Pro can overcome simple steps, a capability that the Edge S5A also possesses but limited to 20 mm in height. This function allows it to navigate thresholds, thick carpets and small uneven surfaces without getting blocked.
An exclusive feature of the 2025 model is its own voice assistant, which allows direct interaction with the robot without needing to use the mobile app. Both units are compatible with external assistants such as Alexa or Google Home, but having an integrated one adds convenience in day-to-day use.
Multifunctional Cleaning Base
Both bases feature auto-emptying of the dust bin, mop washing with hot water and drying with hot air. The dust bag capacity is 2.5 litres in the Qrevo Curv 2 Pro and 2.7 litres in the Edge S5A, a minimal difference that does not affect practical maintenance.
The clean water tanks are identical at 4 litres, but the dirty water tank varies: 3 litres in the 2025 model versus 3.5 litres in the 2024 one. This difference is also not critical in real use. Neither includes a detergent tank nor plumbing connection, features that some models from other ranges do incorporate.
The Qrevo Curv 2 Pro's 3.0 tray self-cleaning system represents an incremental improvement over the 2.0, but both guarantee that the washing area remains hygienic without manual intervention.
Dimensions
Height is where the technological evolution is most noticeable. The Roborock Qrevo Curv 2 Pro measures 79.8 mm tall thanks to its retractable LiDAR, whilst the Qrevo Edge S5A reaches 98 mm due to its fixed turret. Those nearly 2 centimetres of difference allow the more recent model to access under furniture, beds and sofas where the previous one cannot enter.
The diameter is identical in both, at 352 mm. As for the bases, the Qrevo Curv 2 Pro has a cubic shape of 450 mm in all directions, occupying more floor space but being more compact in height (450 mm versus 521 mm). The Edge S5A, at 340 mm wide, 487 mm deep and 521 mm tall, is narrower but also taller and deeper. It's advisable to measure the available space before deciding.
Real-World Usage Experience
In homes with pets, the Roborock Qrevo Curv 2 Pro offers clear advantages: greater suction power, specific animal recognition and liftable main brush that facilitates hair cleaning. Its extended runtime is also useful in large homes where pets generate dirt in multiple rooms.
For homes with low furniture, the lower height of the Qrevo Curv 2 Pro significantly expands accessible areas. This can make the difference between having to manually clean under the bed or completely delegating that task to the Roborock robot vacuum.
The remote camera access of the 2025 model adds extra value for those seeking occasional home surveillance or pet supervision during prolonged absences. Night vision via LED allows this function to be useful even in low light.
Regarding mopping, both models offer reliable results thanks to hot water washing and efficient drying of the mops. The Qrevo Curv 2 Pro's ability to automatically remove the mops simplifies alternating between pure vacuuming and mopping, something especially practical in homes with areas of hard flooring and carpets.
Conclusion: Which to Choose?
Choose the Roborock Qrevo Curv 2 Pro if you have a large home that requires greater runtime, you live with pets and need maximum obstacle recognition, you value being able to access under low furniture, you want the maximum available suction power or you're looking for advanced functions such as remote camera and own voice assistant. Its reduced height and ability to lift the main brush make it the most versatile and complete option.
Choose the Roborock Qrevo Edge S5A if your home does not exceed 150-200 m², you don't have height restrictions under furniture, you're looking for a Roborock robot vacuum with excellent value for money, and you don't need camera functions or advanced pet recognition. It remains a very capable unit with complete multifunctional base and reliable performance in vacuuming and mopping.
Ultimately, the generational difference is especially noticeable in intelligent navigation, runtime and robot height. For most homes without special requirements, the Edge S5A performs perfectly. But if you're looking for the best robot vacuum with the most advanced technology and maximum versatility, the Qrevo Curv 2 Pro justifies the investment.
