Introduction
The Roborock Qrevo Curv 2 Pro and the Xiaomi X20 Max represent two distinct approaches within robot vacuum cleaners with multifunction bases. The Roborock model arrives in 2025 with specifications aimed at the highest end of the market, whilst the Xiaomi X20 Max, launched in 2024, positions itself as a more accessible alternative without sacrificing essential functions. Both devices integrate vacuuming and mopping with bases that wash and dry the mops automatically, ensuring reduced maintenance. The choice between one or the other will depend on the type of home, cleaning needs and the level of automation sought.
Power and Suction
The difference in suction power is very significant. The Roborock Qrevo Curv 2 Pro reaches 25,000 Pa, more than triple the Xiaomi X20 Max's 8,000 Pa. This difference is especially noticeable on medium or long pile carpets, where the ability to extract embedded dirt marks the distance between a superficial clean and a deep one.
The brushing system also shows important differences. The Roborock is equipped with the DuoDivide anti-tangle brush, designed to push hairs towards the central suction gap and prevent tangles. Additionally, this brush can be lifted during mopping, something the Xiaomi with its TriCut 3.0 brush cannot do. The TriCut combines bristles with blades that cut hairs, reducing tangles, but without reaching the level of effectiveness of the Roborock system.
As for the side brush, the Qrevo Curv 2 Pro includes extension to better reach corners and anti-tangle technology, two features absent in the X20 Max. This improves edge sweeping and reduces manual maintenance. For homes with long-haired pets, these differences can be decisive.
Mopping
Both robots use two rotating mops and feature edge extension, allowing more complete mopping on skirting boards and corners. However, the mop lifting system differs: the Roborock offers variable lifting between 7 and 17 mm, adapting better to different types of carpets and obstacles, whilst the Xiaomi maintains a fixed lifting of 10 mm.
A key difference appears in automatic mop removal. The Qrevo Curv 2 Pro can remove the mops at the base when it only needs to vacuum, preventing them from getting unnecessarily wet or dragging moisture through areas where mopping is not desired. The X20 Max lacks this function.
Dirt detection marks another notable difference. The Roborock model detects both dirt on the mops and on the floor, adjusting mopping according to the actual need of each area. This allows it to go over dirtier areas without manual intervention. The Xiaomi does not integrate any of these detection systems, maintaining standard mopping in all areas.
The bases of both models wash the mops with hot water and dry them with hot air, ensuring hygiene and preventing bad odours. The Roborock adds tray self-cleaning 3.0, which further reduces manual maintenance of the base.
Navigation System
The Roborock Qrevo Curv 2 Pro features a retractable LiDAR system combined with dual AI camera capable of recognising up to 200 different obstacles, including pets. This configuration allows more precise and adaptive navigation, especially in homes with young children or animals where objects constantly change position. Additionally, it offers remote camera access, allowing home monitoring from the app.
The Xiaomi X20 Max uses a LiDAR 3.0 turret with front 3D laser sensor, but without AI camera. This limits its object recognition capability and does not allow remote camera access. Both devices include LED for night vision and obstacle avoidance through 3D sensors, but the Roborock's level of intelligence and adaptation is superior.
The Qrevo Curv 2 Pro's SmartPlan 3.0 includes AI stain recognition, automatically adjusting cleaning according to the type of dirt detected. The X20 Max features AI intelligent cleaning but without specifying stain recognition, suggesting a more basic level of automation.
Autonomy and Battery
The Roborock Qrevo Curv 2 Pro's 6,400 mAh battery offers 290 minutes of autonomy, more than double the Xiaomi X20 Max's 120 minutes with its 5,200 mAh. This difference is critical in large homes or complex layouts where the robot needs to complete long cycles without interruptions.
In practice, the Qrevo Curv 2 Pro can clean large homes in a single run, whilst the X20 Max will need to return to the base to recharge on surfaces above a certain size. For small or medium flats, the Xiaomi's autonomy may be sufficient, but in homes over 100 square metres the difference becomes evident.
Smart Functions
The Roborock Qrevo Curv 2 Pro incorporates a simple step system that allows it to overcome obstacles more effectively than the Xiaomi X20 Max, which is limited to 20 mm. Although the exact height of the Roborock's system is not specified, its designation suggests a superior capability for navigating thresholds, cables or level changes common in homes.
An exclusive function of the Qrevo Curv 2 Pro is its own voice assistant, which allows controlling the robot through direct commands without the need for external assistants. Both models are compatible with Alexa and Google Home, but the Roborock's integrated assistant adds an extra layer of convenience for those who prefer not to depend on external ecosystems.
Multifunction Cleaning Base
Both bases include auto-emptying of the dust bin, mop washing with hot water and drying with hot air. The clean water tanks are identical (4 litres), and the dust bags have the same capacity of 2.5 litres. The dirty water tank differs slightly: 3 litres in the Roborock versus 3.8 litres in the Xiaomi.
The Qrevo Curv 2 Pro's tray self-cleaning 3.0 marks an important difference in maintenance. This system automatically cleans the tray where the mops are washed, reducing dirt accumulation and the need for manual intervention. The X20 Max lacks this function, which means periodic manual cleaning to maintain the base's hygiene.
Neither model includes a detergent tank, UV disinfection or plumbing connection, so maintenance of the water tanks must be done manually in both cases.
Dimensions
The diameter of both robots is practically identical: 352 mm for the Roborock and 350 mm for the Xiaomi. The key difference is in height: 79.8 mm for the Qrevo Curv 2 Pro versus 97 mm for the X20 Max. This difference of more than 17 mm allows the Roborock to access under low furniture, beds with little height or spaces where the Xiaomi would not fit.
The dimensions of the bases also differ. The Roborock has a square base of 450 mm on all sides, whilst the Xiaomi has a narrower base (340 mm wide) but taller (563 mm versus 450 mm). This can influence the base's location depending on available space: the Roborock needs more floor surface, but the Xiaomi requires greater clearance height.
Real-World Experience
For large homes, the Roborock Qrevo Curv 2 Pro offers clear advantages: its 290-minute autonomy allows cleaning large surfaces without interruptions, whilst its 25,000 Pa power guarantees deep results on carpets. The dirt detection system and stain recognition optimise cleaning without the need for manual configurations.
In homes with pets, the Roborock's DuoDivide anti-tangle brush significantly reduces maintenance, especially with long-haired animals. The anti-tangle and extendable side brush improves hair collection in corners. The Xiaomi, with its TriCut 3.0 brush, offers a more basic solution that requires more frequent manual cleaning.
The Qrevo Curv 2 Pro's 79.8 mm height is ideal for homes with low furniture or beds with little distance to the floor. The Xiaomi, at 97 mm, will be excluded from these spaces. For small or medium flats without these limitations, the X20 Max's height is not a problem.
The Roborock's automatic mop removal allows scheduling mixed cleaning (vacuuming in bedrooms, mopping in common areas) without manual intervention. The Xiaomi requires manually removing the mops if you only wish to vacuum certain areas.
Conclusion: Which to Choose?
Choose the Roborock Qrevo Curv 2 Pro if: You're looking for the best robot vacuum cleaner on the market without compromises. Ideal for large homes requiring extended autonomy, homes with long-haired pets where reduced maintenance is a priority, or if you need to access under low furniture thanks to its 79.8 mm height. The dual AI camera, recognition of 200 obstacles and pets, dirt detection on mops and floor, and tray self-cleaning 3.0 justify the investment for those seeking total automation and minimal manual intervention.
Choose the Xiaomi X20 Max if: You prioritise good value for money in a robot with a complete multifunction base. Suitable for small or medium flats where the 120-minute autonomy is sufficient, and where the 97 mm height does not limit access under furniture. It offers the essential functions of vacuuming, mopping, washing and drying mops with hot water and air, although without the advanced AI capabilities, dirt detection or automatic mop removal of the Roborock. A solid option for those who don't need the maximum level of automation but value the convenience of a multifunction base.
