Introduction
Choosing between the Dreame L50s Pro Ultra, the Roborock Qrevo Curv 2 Pro and the Roborock Saros 10R involves weighing up three high-end propositions with different philosophies. The Dreame model arrived on the market in 2026 with extremely powerful suction and an innovative dual brush system. The two Roborock units, launched in 2025, represent different approaches: the Qrevo Curv 2 Pro stands out for its high-capacity battery and compact design with retractable LiDAR, whilst the Saros 10R integrates StarSight 2.0 technology and offers warm water for mopping.
All include complete multifunctional bases that wash and dry the mops, but the differences in robot height, tank capacity and navigation systems define distinct usage profiles. We're talking about robots designed for medium or large homes, with users seeking maximum autonomy and minimum maintenance.
Power and Suction
Suction power marks important differences in this robot vacuum comparison. The Dreame L50s Pro Ultra leads with 30,000 Pa, a figure that clearly exceeds the 25,000 Pa of the Roborock Qrevo Curv 2 Pro and the 18,500 Pa of the Roborock Saros 10R. This difference is particularly noticeable on long-pile carpets or when there are pets at home.
The brushing system also varies. The Dreame features a dual main brush, whilst the two Roborock models have the DuoDivide anti-tangle system, designed to push hair towards the centre and reduce tangles. All three can raise the main brush during mopping, preventing it from getting unnecessarily wet.
As for the side brush, all incorporate an extendable design to better reach corners and an anti-tangle version. The difference lies in the lifting: the Dreame L50s Pro Ultra and the Saros 10R can raise the side brush during mopping, something the Qrevo Curv 2 Pro doesn't do. This can be relevant if you mop frequently and want to prevent the brush from splashing dirty water.
Mopping
All three robots use two rotating mops for mopping, a system that offers good results on hard floors. All extend the mops to better reach edges, although the Dreame L50s Pro Ultra adds a specific movement (Roboswing) that helps get the mops under furniture overhangs.
Mop lifting presents different figures: the Dreame reaches 10.5 mm, the Qrevo Curv 2 Pro between 7 and 17 mm, and the Saros 10R between 12 and 22 mm. This last figure allows the Saros 10R to climb thicker carpets without wetting the mops. In practice, this can make the difference if you have medium-pile carpets at home.
A notable difference appears in the mopping water temperature. The Roborock Saros 10R mops with warm water, whilst the Dreame L50s Pro Ultra and the Qrevo Curv 2 Pro use cold water. Warm water helps dissolve grease better and can improve results in kitchens.
All wash the mops with hot water in the base and dry them with hot air, which speeds up drying and prevents bad odours. They also detect dirt both on the mops and on the floor, activating additional washing or scrubbing cycles when necessary. All three can automatically detach the mops at the base if you only want to vacuum.
Navigation System
The Dreame L50s Pro Ultra has a traditional LiDAR turret, which explains its greater height of 103.8 mm. The Roborock Qrevo Curv 2 Pro integrates retractable LiDAR, reducing the height to 79.8 mm and facilitating access under low furniture. The Saros 10R, with the same height, incorporates the StarSight 2.0 system.
All feature dual AI camera, front 3D laser sensor and LED for night vision. Obstacle recognition capability varies: the Dreame identifies 220 different objects, the Qrevo Curv 2 Pro 200 and the Saros 10R 108. More recognised obstacles means greater precision when avoiding cables, slippers or toys.
All three recognise pets and allow remote access to the camera. Only the Dreame L50s Pro Ultra detects curtains, a useful function to prevent the robot from getting trapped in long curtains or tablecloths.
Autonomy and Battery
The Roborock Qrevo Curv 2 Pro battery stands out with 6,400 mAh and 290 minutes of autonomy, sufficient to clean large homes in a single run. The Roborock Saros 10R has the same battery capacity but offers 180 minutes of autonomy, probably because the warm water and other systems consume more energy.
The Dreame L50s Pro Ultra features a 5,200 mAh battery. Although autonomy in minutes is not specified, the lower capacity suggests it's designed for medium-sized homes. The higher suction power also influences energy consumption.
Smart Features
All three robots overcome simple steps, although exact heights are not detailed in the table. All incorporate their own voice assistant and compatibility with Alexa and Google Home, facilitating voice control.
The Dreame L50s Pro Ultra integrates CleanGenius, the Qrevo Curv 2 Pro and the Saros 10R use SmartPlan. These intelligent cleaning systems adjust power and mopping mode according to floor type and detected dirt level. The Saros 10R specifies the RR Mason 11.0 algorithm, an evolution of Roborock's software.
Multifunctional Cleaning Base
All three bases auto-empty the dust bin, wash the mops with hot water and dry them with hot air. The Dreame L50s Pro Ultra and the Qrevo Curv 2 Pro include third-generation (3.0) tray self-cleaning, whilst the Saros 10R has version 2.0. Generation 3.0 is usually more effective at removing residue from the washing tray.
The Dreame L50s Pro Ultra and the Saros 10R incorporate a detergent tank that dispenses during mop washing. The Qrevo Curv 2 Pro doesn't include this function, which means cleaning with water alone or manually adding detergent to the clean water tank.
Tank capacity varies. The Dreame offers 3.2 litres dust bag, 4.5 litres clean water and 4 litres dirty water. The Qrevo Curv 2 Pro and the Saros 10R have 2.5 litres dust bag, 4 litres clean water and 3 litres dirty water. Greater capacity means fewer visits to empty or refill, something to consider in large homes.
Only the Dreame L50s Pro Ultra offers an optional plumbing connection kit, which is purchased separately. It allows the base to be connected directly to the drain and water supply, eliminating tank maintenance. None of the three includes integrated connection as standard.
Dimensions
Robot height is crucial for accessing under furniture. The Dreame L50s Pro Ultra measures 103.8 mm due to its traditional LiDAR turret, which may limit its passage under low sofas or beds. The Roborock Qrevo Curv 2 Pro and the Saros 10R, at 79.8 mm, access tighter spaces thanks to retractable LiDAR and the StarSight system respectively.
Diameter is similar across all three: 350 mm on the Dreame, 352 mm on the Qrevo Curv 2 Pro and 353 mm on the Saros 10R. Minimal differences that don't affect real-world use.
The bases present different designs. The Dreame's measures 340 mm wide, 590 mm high and 457 mm deep. The Qrevo Curv 2 Pro has a cubic base of 450 mm in all dimensions. The Saros 10R occupies 381 mm wide, 488 mm high and 475 mm deep. The Dreame's base is taller but narrower, whilst the Qrevo Curv 2 Pro's is more compact and square.
Real-world usage experience
In large homes, the Roborock Qrevo Curv 2 Pro offers the greatest autonomy with 290 minutes of battery, sufficient to clean over 200 m² without recharging. Its compact base facilitates placement in tight spaces. The Saros 10R, with 180 minutes, covers homes up to 150 m² without problems, and the warm water improves mopping in kitchens with accumulated grease.
If you have pets, the Dreame L50s Pro Ultra stands out for its 30,000 Pa suction and dual brush, capable of picking up more hair in a single pass. The Roborocks' DuoDivide system also works well reducing tangles, but the Dreame's extra power makes a difference on carpets with dog or cat hair.
For accessing under low furniture, the two Roborock models are more suitable with their 79.8 mm height. The Dreame, at 103.8 mm, may get blocked under some sofas or low Nordic beds.
The detergent tank on the Dreame and the Saros 10R facilitates deep mopping without manual intervention. The Qrevo Curv 2 Pro requires adding detergent to the clean water if you want to enhance cleaning, which adds a maintenance step.
The Dreame's larger tanks (3.2 L dust, 4.5 L clean water) reduce maintenance frequency in large homes or with daily cleaning. The Roborocks, with slightly smaller tanks, are still sufficient for most households.
Conclusion: Which to choose?
Choose the Dreame L50s Pro Ultra if you're looking for maximum suction power for carpets and pets, value curtain detection and prefer large tanks that reduce maintenance. The optional plumbing connection kit may interest you if you want to completely forget about emptying and refilling the base. Bear in mind its greater height if you have low furniture.
Choose the Roborock Qrevo Curv 2 Pro if you need maximum autonomy for large homes, want a low robot that accesses under any furniture and prefer a compact base. Its 6,400 mAh battery and 290 minutes of autonomy make it the best robot vacuum for large surfaces. The absence of a detergent tank is its main limitation.
Choose the Roborock Saros 10R if you value mopping with warm water to remove grease, are looking for a compact robot that accesses under furniture and want an included detergent tank. Its mop lifting of up to 22 mm allows climbing thicker carpets without problems. It's a balanced option between power, autonomy and advanced mopping functions.
In the end, the differences between these three models respond to different priorities: extreme power and capacity in the Dreame, record autonomy in the Qrevo Curv 2 Pro, and balance with warm water in the Saros 10R. Each one leads in its speciality within this comparison of
