Introduction
This comparison brings together three high-end proposals launched in 2025 that represent the most advanced in automated cleaning. The Dreame Aqua 10 Ultra Roller stands out for incorporating a roller system instead of traditional mops, whilst the Roborock Saros 10R opts for dual mop technology with warm water capabilities. The Dreame X50 Ultra Blanca completes the trio with a balanced approach and the brand's own characteristics.
We're looking at equipment designed for users seeking total home maintenance automation, with multifunctional bases that manage both dust emptying and mop washing and drying. The main difference between them lies in how they approach mopping and suction power, aspects that will determine the user experience depending on the type of home and specific needs.
Power and Suction
The most notable difference in this section is marked by the Dreame Aqua 10 Ultra Roller with its 30,000 Pa of suction power, a figure that far exceeds the Roborock Saros 10R's 18,500 Pa and the Dreame X50 Ultra Blanca's 20,000 Pa. In practice, this translates into greater capacity to extract embedded dirt from carpets or vacuum heavier particles.
The brushing system also presents important variations. The Aqua 10 Ultra and the X50 Ultra feature Dreame's dual HyperStream brush, specifically designed to prevent hair tangles using two brushes anchored at one end. The Roborock Saros 10R, on the other hand, is equipped with the DuoDivide anti-tangle brush, which pushes hairs towards the central gap to facilitate suction.
All three models lift the main brush during mopping and also feature an extendable and liftable side brush, characteristics that improve corner cleaning and prevent dragging dry dirt whilst mopping. All incorporate anti-tangle technology in the side brush.
Mopping
Here we find the most important conceptual difference in this robot vacuum comparison. The Dreame Aqua 10 Ultra Roller uses a roller system with 12N of pressure, similar to traditional mops, which rotates constantly whilst mopping. The other two models employ two rotating mops that scrub the floor with circular movement.
Water temperature marks another relevant distinction. The Roborock Saros 10R mops with warm water, which helps to better dissolve grease and adhered dirt. Both the Aqua 10 Ultra and the X50 Ultra use cold water, although the latter compensates with UV disinfection at the base.
All three extend the mops to reach edges, but the X50 Ultra adds lateral movement during this extension. Mop lifting varies: the Aqua 10 Ultra lifts up to 14 mm and also automatically removes the roller, the Saros 10R lifts between 12-22 mm, and the X50 Ultra reaches 10.5 mm. Only the Roborock automatically removes the mops at the base when a vacuum-only session is programmed, a practical function for homes without mopping zones.
All incorporate dirt detection both on the mops and on the floor, adjusting the cleaning process according to detected needs.
Navigation System
All three robots are equipped with retractable LIDAR and dual RGB camera with front 3D laser sensor, but object recognition capability differs considerably. The Dreame Aqua 10 Ultra identifies up to 240 different obstacles, the X50 Ultra recognises 200, whilst the Roborock Saros 10R remains at 108.
This difference can be particularly noticeable in homes with many objects on the floor or scattered toys. The Aqua 10 Ultra and the X50 Ultra detect curtains, avoiding getting tangled in them; the Saros 10R doesn't include this specific function. All three recognise pets and offer remote camera access with LED for night vision.
Intelligent processing also varies: the Aqua 10 Ultra features the AI Sage 15.0 chip with CleanGenius, the X50 Ultra carries the AI Sage 13.0, and the Saros 10R uses the RR Mason 11.0 algorithm with SmartPlan. All recognise stains using AI and adjust cleaning accordingly.
Autonomy and Battery
All three models incorporate 6,400 mAh batteries, but actual autonomy differs. The Roborock Saros 10R and the Dreame X50 Ultra achieve 180 minutes of operation, whilst the Aqua 10 Ultra remains at 160 minutes. This 20-minute difference is probably due to the higher energy consumption of the roller system and superior suction power.
For medium or large-sized homes, the 180 minutes of the Saros 10R and the X50 Ultra offer greater margin without the need for intermediate recharges. In practice, any of the three manages large surfaces without problems thanks to automatic recharge and resumption.
Smart Functions
All three units overcome simple steps, a useful capability for transitions between rooms with small level changes or thick carpets. All include their own voice assistant in addition to compatibility with Alexa and Google Home, allowing voice command control both through the integrated system and external assistants.
Multifunctional Cleaning Base
All three bases manage automatic emptying of the dust container, mop washing with hot water and drying. However, there are important differences in the washing tray self-cleaning. The Roborock Saros 10R incorporates version 2.0 of this technology, the Dreame X50 Ultra features the third generation, whilst the Aqua 10 Ultra doesn't specify this function.
The X50 Ultra adds UV disinfection, absent in the other two models. Regarding the detergent tank, the Aqua 10 Ultra stands out with a dual tank, allowing the use of different products depending on floor type or dirt level. The other two have a single tank.
Storage capacity varies. The dust bag reaches 3.2 litres on the Aqua 10 Ultra and the X50 Ultra, compared to 2.5 litres on the Saros 10R. The clean water tank measures 4 litres on the first two and 4.5 litres on the X50 Ultra. Dirty water accumulates in 3.5 litres (Aqua 10 Ultra), 3 litres (Saros 10R) and 4 litres (X50 Ultra).
Both the Aqua 10 Ultra and the X50 Ultra offer an optional kit for plumbing connection, which must be purchased separately. The Saros 10R doesn't have this option.
Dimensions
Robot height is crucial for accessing under furniture. The Roborock Saros 10R measures 79.8 mm, making it the lowest of the three and facilitating cleaning under sofas or low beds. The Dreame X50 Ultra reaches 89 mm, whilst the Aqua 10 Ultra reaches 97.5 mm, probably due to the roller system requiring more internal space.
Diameter is similar across all: 350 mm on the Dreame models and 353 mm on the Roborock, with no practical differences in manoeuvrability. The bases present varied dimensions. The X50 Ultra's is the tallest (590.5 mm) but the narrowest (340 mm wide), whilst the Aqua 10 Ultra's measures 420 mm wide by 500 mm high. The Saros 10R's base occupies 381 mm wide by 488 mm high, being the most compact in surface area but the deepest at 475 mm.
Real-world user experience
For large homes, the Roborock Saros 10R and the Dreame X50 Ultra offer an advantage with their 180 minutes of autonomy. The Saros 10R, moreover, is ideal for homes with low furniture thanks to its 79.8 mm height. The Roborock's warm water mopping system can make a difference in kitchens with grease or floors requiring deeper cleaning.
The Dreame Aqua 10 Ultra Roller provides the greatest suction power, fundamental for long-pile carpets or homes with heavy traffic. Its roller system provides a different type of mopping, closer to that of a traditional mop. The dual detergent tank allows cleaning customisation according to zones.
With pets, all three models work well thanks to their anti-tangle brush systems, but the Aqua 10 Ultra's greater power facilitates the extraction of hair embedded in fabrics. The recognition of 240 objects also helps avoid toys or feeding bowls.
The Dreame X50 Ultra positions itself as a balanced option: good suction power, extensive autonomy, UV disinfection and third-generation tray self-cleaning. Its 89 mm height allows access to more spaces than the Aqua 10 Ultra without reaching the minimum of the Saros 10R.
Conclusion: Which one to choose?
Choose the Dreame Aqua 10 Ultra Roller if you're looking for maximum suction power and prefer the roller mopping system. It's the best option for thick carpets, homes with pets that shed a lot of hair and dwellings where suction power takes priority over other considerations. The dual detergent tank adds versatility for different floor types. Bear in mind that its 97.5 mm height limits access under low furniture.
Choose the Roborock Saros 10R if you need the lowest robot on the market to clean under furniture with little height. Mopping with warm water is advantageous in kitchens or areas with grease, and automatic mop removal at the base optimises vacuum-only sessions. With 180 minutes of autonomy, it manages large homes without problems. The Roborock brand provides proven reliability and an app recognised for its stability.
Choose the Dreame X50 Ultra Blanca if you're looking for balance between power, autonomy and advanced functions. UV disinfection, third-generation tray self-cleaning and recognition of 200 objects make it a very complete option. Its 89 mm height allows access to more spaces than the Aqua 10 Ultra, and the 180 minutes of autonomy covers large surfaces. The 4-litre dirty water tank is the largest of the three, reducing the frequency of manual emptying.
