Introduction
Roborock maintains its leadership in the robot vacuum market with two proposals that, although sharing the Qrevo surname, respond to different needs. The Qrevo Curv 2 Pro arrives in 2025 as one of the brand's most advanced models, whilst the Qrevo Slim was introduced in 2024 with a different approach: maximum efficiency in reduced spaces.
The Curv 2 Pro is designed for large homes where power, autonomy and the ability to overcome complex obstacles make the difference. The Slim, on the other hand, prioritises compactness and access to low areas without sacrificing a complete multifunction base. Both include twin rotating mop technology and advanced navigation systems, but the differences in power, battery and intelligent functions are notable.
Power and Suction
The most evident difference in this robot vacuum comparison is in suction power. The Roborock Qrevo Curv 2 Pro reaches 25,000 Pa, more than double the 11,000 Pa of the Qrevo Slim. This gap is particularly noticeable on thick carpets or when there's pet hair accumulation.
Both models feature the DuoDivide main brush, Roborock's anti-tangle system that pushes hairs towards the central gap to prevent them from wrapping around. This proves very practical in homes with pets. The brush lifts during mopping in both cases, which prevents dragging wet dirt across already clean surfaces.
Where there is a difference is in the side brush. The Curv 2 Pro's incorporates anti-tangle technology, whilst the Slim uses a conventional design. Both feature side extension to improve corner cleaning, but neither lifts this brush during mopping.
Mopping
Both robots mop with two rotating mops that extend towards the edges. This feature allows them to reach skirting boards and corners that many robots fail to clean properly. Mop lifting works differently: the Curv 2 Pro offers an adjustable range between 7 and 17 mm, whilst the Slim maintains a fixed lift of 10 mm. That versatility of the 2025 model helps to better adapt to carpets of different thicknesses.
An exclusive function of the Qrevo Curv 2 Pro is automatic mop removal at the base. When you only need to vacuum, the robot removes the mops without manual intervention. The Slim doesn't have this option, although you can remove them yourself if you prefer.
Both models detect dirt on both the mops and the floor, which triggers additional washing or scrubbing cycles when necessary. The mopping water is cold in both cases. The bases wash the mops with hot water and dry them with hot air, a standard feature in Qrevo models that guarantees hygiene and prevents bad odours.
Navigation System
The Roborock Qrevo Curv 2 Pro incorporates a retractable LiDAR that hides when not in use, reducing the robot's effective height at certain times. The Qrevo Slim features the StarSight 1.0 system, also laser-based but with a different approach. Both include dual AI camera and front 3D laser sensor for obstacle avoidance.
Recognition capacity marks an important difference. The Curv 2 Pro identifies up to 200 types of obstacles, almost three times more than the Slim's 73. This translates into better adaptation to complex environments with many objects on the floor. Both recognise pets and allow remote camera access, as well as featuring LED for night vision.
In artificial intelligence, the Curv 2 Pro features SmartPlan 3.0 with stain recognition, a function that detects particularly dirty areas and cleans them with greater intensity. The Slim remains at SmartPlan 1.0, without this specific stain identification capability.
Autonomy and Battery
The Qrevo Curv 2 Pro's battery has 6,400 mAh and offers up to 290 minutes of continuous operation. The Qrevo Slim features a 5,200 mAh battery with 180 minutes of autonomy. In practice, this means the Curv 2 Pro can clean much larger homes in a single session without returning to the base to recharge.
For homes over 150 square metres, that extra autonomy of the 2025 model proves decisive. The Slim remains sufficient for standard flats or medium-sized homes, but in large areas it will need to pause for recharging.
Intelligent Functions
The Qrevo Curv 2 Pro is designed to overcome simple steps, a capability not specified in exact millimetres but which goes beyond conventional obstacles. The Qrevo Slim, on the other hand, can navigate height differences of up to 20 mm, sufficient for most transitions between rooms or thick carpets.
Both robots integrate their own voice assistant and are compatible with Alexa and Google Home. This dual option facilitates voice control without depending exclusively on external assistants.
Multifunction Cleaning Base
The bases of these two models share many features: they auto-empty the dust bin, wash the mops with hot water and dry them with hot air. However, there are important differences in tray self-cleaning. The Curv 2 Pro features version 3.0, more advanced than the Slim's 1.0. This influences long-term maintenance, reducing the frequency with which you need to manually clean the tray.
The dust bag capacity is 2.5 litres in the Curv 2 Pro and 2.7 litres in the Slim. Both clean water tanks hold 4 litres, but the dirty water tank differs: 3 litres in the Curv 2 Pro versus 3.5 litres in the Slim. These small variations don't greatly affect daily use.
Neither includes a detergent tank nor plumbing connection, nor an optional kit for plumbing installation or UV disinfection.
Dimensions
The diameter is practically identical: 352 mm in the Curv 2 Pro and 353 mm in the Slim. Height is where a minimal but relevant difference appears: 79.8 mm versus 82 mm. The Curv 2 Pro is slightly lower, although in practice both pass under most furniture without problems.
Where it does change considerably is in the base dimensions. The Qrevo Curv 2 Pro's measures 450 x 450 x 450 mm, forming a perfect cube. The Slim's is much more compact in width (340 mm) but taller (521 mm) and deeper (487 mm). If you have limited horizontal space, the Slim proves easier to position. For ample spaces, the Curv 2 Pro's square base may prove more stable and aesthetic.
Real-World User Experience
The Roborock Qrevo Curv 2 Pro is designed for large homes where the autonomy of almost 5 hours allows cleaning the entire house without interruptions. The 25,000 Pa power makes it especially effective in homes with pets, carpets or heavy dirt accumulation. The anti-tangle side brush adds points if you have animals with long hair.
The recognition of 200 obstacles and SmartPlan 3.0 with stain detection make it a highly autonomous robot that takes intelligent decisions during cleaning. Automatic mop removal adds convenience if you alternate vacuum-only days with complete mopping days.
The Qrevo Slim works best in flats or medium-sized houses where the 180 minutes of battery are sufficient. Its more compact base facilitates installation in reduced spaces. Although it has less power, the 11,000 Pa remains adequate for hard floors and thin carpets. The lack of stain recognition and fewer identified obstacles make it somewhat less autonomous, but it remains a very capable robot.
Conclusion: Which to Choose?
Choose the Roborock Qrevo Curv 2 Pro if you live in a large house over 150 square metres, have pets with long hair, thick carpets or need maximum suction power. Also if you value total autonomy with functions such as automatic mop removal or advanced stain recognition. It's the best option for those seeking Roborock's most complete robot vacuum regardless of the space the base occupies.
Choose the Roborock Qrevo Slim if your priority is a compact base that fits in reduced spaces, you live in a medium-sized flat and don't need the extreme autonomy of the Curv 2 Pro. It still offers excellent mopping with extendable mops, dirt detection and intelligent navigation, all in a more discreet format. It's ideal if you're looking for a balance between advanced features and space occupation.
Ultimately, this comparison between the Qrevo Curv 2 Pro and the Qrevo Slim demonstrates that Roborock has managed to create two different robots under the same family. One opts for maximum power and autonomy, the other for efficiency in tight spaces. Which robot to choose depends on the size of your home and whether you need that extra power for carpets or pets.
