Introduction
This comparison brings together three 2025 models that represent the most advanced in robotic cleaning: the Dreame L50 Pro Ultra, the Roborock Saros 10R and the Dreame X50 Ultra Blanca. All three units incorporate a complete multifunction base with mop washing and drying, navigation systems with artificial intelligence and mopping capabilities that go beyond the basics. We're talking about robots designed for users seeking total automation and professional results.
Although they share many high-end features, the differences between them can determine the choice depending on the type of home, the presence of pets or the specific needs of each household. The Saros 10R comes with Roborock's seal of quality, whilst the two Dreame models offer competitive proposals with interesting nuances between them.
Power and Suction
Suction power shows clear differences. The Dreame X50 Ultra Blanca leads with 20,000 Pa, followed by the L50 Pro Ultra with 19,500 Pa and the Roborock Saros 10R with 18,500 Pa. In practice, these figures translate into the ability to extract embedded dirt from carpets or vacuum heavier debris without needing repeat passes.
Where we do find a relevant technical difference is in the main brush system. The Saros 10R mounts Roborock's DuoDivide anti-tangle design, which pushes hair towards the central suction gap to minimise tangles. The two Dreame models incorporate the dual HyperStream brush, with two brushes anchored at one end that also effectively reduce tangles. Both solutions work well with pets, albeit with different technical approaches.
All three robots lift the main brush during mopping and feature an extendable, liftable and anti-tangle side brush. This ensures efficient sweeping in corners without interfering with the mops when mopping.
Mopping
All use two rotating mops, but the differences appear in the details. The Dreame L50 Pro Ultra and X50 Ultra Blanca extend the mops with Roboswing movement, a system that makes the robot perform a small wiggle to get the mop under furniture overhangs. The Saros 10R extends the mops to reach edges, but without that additional movement.
Mop lift marks an important difference. The Roborock Saros 10R can lift the mops between 12 and 22 mm, a height that allows it to pass over thick carpets without wetting them. The two Dreame models remain at 10.5 mm, sufficient for thin carpets but more limited on high-pile carpets.
The Saros 10R mops with warm water, which helps to better dissolve grease and certain stains. The two Dreame models use cold water. All wash the mops with hot water in the base, but only the Roborock heats the water that it then applies to the floor during mopping.
All three detect dirt both on the mops and on the floor, adjusting cleaning as necessary. They also automatically remove the mops at the base when they only need to vacuum, avoiding dragging them unnecessarily.
Navigation System
The Dreame L50 Pro Ultra and X50 Ultra Blanca mount retractable LiDAR, whilst the Roborock Saros 10R uses the StarSight 2.0 system. All three incorporate dual cameras with artificial intelligence, front 3D laser sensor and LED for night vision, ensuring precise navigation even in low-light conditions.
Obstacle recognition capability varies notably. The Dreame X50 Ultra Blanca identifies up to 200 different objects, the L50 Pro Ultra recognises 180 and the Saros 10R remains at 108. This can be particularly noticeable in homes with many objects on the floor or complex spaces. All three recognise pets, but only the Dreame models detect curtains, avoiding tangles with this type of fabric.
All offer remote camera access, allowing you to monitor the home from the mobile app. The processor also differs: the Dreame models use AI Sage 13.0 with CleanGenius algorithm, whilst the Roborock mounts RR Mason 11.0 with SmartPlan.
Autonomy and Battery
Battery capacity is identical across all three models: 6,400 mAh. However, the declared autonomy shows differences. The Dreame L50 Pro Ultra reaches 200 minutes of continuous operation, whilst both the Saros 10R and X50 Ultra Blanca remain at 180 minutes.
Those additional 20 minutes of the L50 Pro Ultra can make a difference in very large homes, although in practice all have sufficient autonomy to complete cleaning of over 200 square metres without needing an intermediate recharge.
Smart Functions
All three robots overcome simple steps, allowing them to navigate small level changes such as those between rooms or when moving from wooden flooring to tiles. None incorporates a robotic arm.
All include their own voice assistant and compatibility with external assistants such as Alexa or Google Home, facilitating control through voice commands without needing to open the app.
Multifunction Cleaning Base
All three bases are complete multifunction units: they auto-empty the dust container, wash the mops with hot water and dry them with hot air. All incorporate a detergent tank to dispense product during mop washing.
Washing tray self-cleaning presents technical differences. The Dreame L50 Pro Ultra and X50 Ultra Blanca mount the third-generation system, whilst the Saros 10R uses version 2.0. This implies greater automation in the base's own maintenance on the Dreame models.
Only the Dreame X50 Ultra Blanca includes UV disinfection, an extra that may interest users particularly concerned about sanitisation.
Storage capacity also varies. The Dreame models have a 3.2-litre dust bag, 4.5-litre clean water tank and 4-litre dirty water tank. The Saros 10R reduces these figures to 2.5 litres for the bag, 4 litres of clean water and 3 litres of dirty water. In large homes or those with pets, the Dreame models' larger tanks require less frequent emptying.
The Dreame models offer a plumbing connection kit as an optional accessory, although it must be purchased separately. The Saros 10R does not have this option available.
Dimensions
The Roborock Saros 10R stands out for its reduced height: just 79.8 mm. The two Dreame models measure 89 mm. Those nearly 10 mm of difference allow the Saros 10R to slip under lower furniture, such as some sofas or beds with little clearance from the floor.
The diameter is practically identical: 350 mm on the Dreame models and 353 mm on the Roborock. As for the bases, the Dreame ones measure 340 mm wide, 590.5 mm high and 456.7 mm deep. The Saros 10R's is wider (381 mm) and lower (488 mm), with 475 mm depth. It's advisable to measure the available space before deciding, especially if the base will go in a tight spot.
Real-World User Experience
For large homes, the Dreame L50 Pro Ultra offers greater autonomy, larger tanks and recognition of more obstacles in the case of the X50 Ultra Blanca. The larger dust bag capacity reduces maintenance frequency, something that's appreciated when there's a lot of surface area to clean.
If there are pets, all three models work well thanks to their anti-tangle brushes, although the greater power of the X50 Ultra Blanca can be advantageous with abundant hair. This model's UV disinfection also provides an extra hygiene benefit.
In homes with thick carpets, the Roborock Saros 10R has a clear advantage thanks to its mop lift of up to 22 mm. For low furniture, its lower height allows it to access where the others cannot reach.
The Saros 10R's warm water mopping is more effective against grease and stubborn stains. The Dreame models compensate with Roboswing movement to better reach corners and with curtain detection, avoiding problems with this type of obstacle.
Conclusion: Which to Choose?
Choose the Dreame L50 Pro Ultra if you're looking for the greatest autonomy of the three (200 minutes), need large tanks to reduce maintenance and value the third-generation tray self-cleaning system. It's the balanced option within the Dreame range, with a good relationship between features and price.
Choose the Roborock Saros 10R if you have low furniture that the robot needs to pass under (it's the lowest at 79.8 mm), have thick carpets requiring mop lift of up to 22 mm, or prefer warm water mopping to improve grease cleaning. Roborock's reliability and its app are also compelling arguments.
Choose the Dreame X50 Ultra Blanca if you want maximum suction power (20,000 Pa), the greatest obstacle recognition (200 objects) and value extras such as UV disinfection. It's Dreame's most complete model, ideal for those seeking all available functions and don't mind investing a bit more.
