Introduction
This comparison analyses three models launched in 2025 that represent different approaches within the premium range. The Dreame L50 Pro Ultra and the Mova V50 Ultra share technological DNA, whilst the Roborock Saros 10R opts for established proprietary solutions. All three feature complete multifunction bases with mop washing and drying, advanced navigation with dual cameras and suction capabilities exceeding 18,000 Pa.
These are robots designed for homes seeking total automation of floor maintenance, with sufficient autonomy for large surfaces and mopping systems that go beyond simple wet dragging. Differences in power, tank capacity and some technical details define distinct usage profiles.
Power and Suction
The Mova V50 Ultra leads in raw power with 24,000 Pa, a figure that exceeds the Dreame L50 Pro Ultra by 4,500 Pa and the Roborock Saros 10R by 5,500 Pa. In practice, this difference can be particularly noticeable on medium-pile carpets or when there is significant dirt accumulation in tile joints.
The brushing system shows different philosophies. The Dreame L50 Pro Ultra and the Mova V50 Ultra feature dual HyperStream brush, a design with two rollers anchored at one end that minimises long hair tangles. The Roborock Saros 10R opts for its DuoDivide anti-tangle brush, which pushes hairs towards the central gap to facilitate direct suction. All three systems are effective against hair, although the approach differs.
All include an extendable side brush to improve coverage in corners and lifting of both the main brush and side brush during mopping. This prevents dragging wet dirt when the robot is mopping. All three side brushes incorporate anti-tangle design, an aspect that facilitates maintenance in homes with pets.
Mopping
All three models use a twin rotating mop system, but differences in water temperature mark important distinctions. The Dreame L50 Pro Ultra works with cold water, the Roborock Saros 10R goes up to warm water and the Mova V50 Ultra reaches hot water for mopping the floor. Temperature influences the dissolution of grease and adhered dirt, especially in kitchens.
Both the Dreame and Mova incorporate an additional movement system in the mop extension, which adds extra displacement to better reach edges. The Roborock also extends the mops, although without that complementary movement. The Roborock Saros 10R's mop lift stands out with 12-22 mm adjustable, compared to the fixed 10.5 mm of Dreame and Mova. Those extra millimetres allow crossing short-pile carpets without wetting them.
All three bases wash the mops with hot water during the automatic cleaning process and dry them with hot air. The Dreame and Mova feature third-generation tray self-cleaning, whilst the Roborock has version 2.0. All three detect dirt both on the mops and on the floor to adjust passes and rewashes. Additionally, they can automatically detach the mops at the base when you only need to vacuum.
Navigation System
The Dreame L50 Pro Ultra and the Mova V50 Ultra use retractable LiDAR, which hides when not in use to reduce effective height under furniture. The Roborock Saros 10R opts for its StarSight 2.0 system, a proprietary combination of sensors that doesn't require a visible laser tower. All three integrate dual AI camera, front 3D laser sensor and LED for night vision.
Obstacle recognition capability varies notably: the Mova V50 Ultra identifies up to 200 different types, the Dreame L50 Pro Ultra reaches 180 and the Roborock Saros 10R stops at 108. In homes with many objects on the floor or scattered toys, this difference can translate into greater precision for avoiding without touching.
The Dreame and Mova detect curtains and adjust their behaviour to avoid getting trapped, a function that the Roborock Saros 10R doesn't include. All three recognise pets and allow remote camera access for surveillance or monitoring. The Dreame L50 Pro Ultra's algorithm is AI Sage 13.0 and the Roborock's is RR Mason 11.0; the Mova doesn't specify a specific version.
Autonomy and Battery
All three robots feature a 6,400 mAh battery, but effective autonomy differs. The Mova V50 Ultra reaches 220 minutes, the Dreame L50 Pro Ultra achieves 200 and the Roborock Saros 10R stops at 180. This difference may be due to software optimisations or different consumption levels of the navigation and processing systems.
For homes up to 150-180 m², any of the three completes cleaning in a single session. On surfaces exceeding 200 m², the Mova V50 Ultra offers greater margin without needing intermediate recharging. The 40-minute difference between the Mova and the Roborock can mean an additional recharge in very large homes with multiple floors.
Smart Functions
All three robots overcome simple thresholds up to 2-2.2 cm, sufficient capability to transit between rooms with small level changes or thick carpets. None incorporates a robotic arm, a function that remains exclusive to very specific market models.
All include a proprietary voice assistant integrated into the robot, in addition to compatibility with Alexa and Google Home. This allows voice control both through the usual assistants and using the robot's internal system for queries or quick adjustments without needing the app.
Multifunction Cleaning Base
All three bases perform auto-emptying of the dust bin, hot water washing of the mops and hot air drying. The Dreame L50 Pro Ultra and the Mova V50 Ultra feature third-generation tray self-cleaning, a more advanced system than the Roborock Saros 10R's version 2.0 for keeping the mop washing area clean.
The Mova V50 Ultra is the only one that adds UV disinfection in the base and dual detergent tank, which allows using two different products depending on the type of floor or task. The Dreame and Roborock include a single detergent tank. Only the Dreame L50 Pro Ultra offers an optional plumbing connection kit, an accessory purchased separately that doesn't come integrated in any of the three models.
The dust bag capacity is 3.2 litres in Dreame and Mova, compared to 2.5 litres for the Roborock. Regarding water tanks, the Dreame carries 4.5 litres of clean water and 4 of dirty; the Roborock 4 litres of clean and 3 of dirty; the Mova 4 litres of clean and 3.5 of dirty. These differences affect the frequency of refilling and emptying in large homes or with intensive mopping.
Dimensions
The diameter of the robots is practically identical: 350 mm in Dreame and Mova, 353 mm in the Roborock. Height does vary: the Roborock Saros 10R measures 79.8 mm, the Dreame L50 Pro Ultra 89 mm and the Mova V50 Ultra 89.5 mm. Those almost 10 mm of difference can determine the possibility of accessing under certain furniture or low beds.
The robots' internal tanks also differ. The Dreame carries 395 ml of dust and 80 ml of water; the Roborock 270 ml of dust and 69 ml of water; the Mova 300 ml of dust and 80 ml of water. Greater internal capacity reduces the frequency with which the robot must return to the base during cleaning, although with multifunction bases this factor loses relevance.
The bases present different proportions. The Dreame L50 Pro Ultra's is the tallest at 590.5 mm, whilst the Roborock measures 488 mm and the Mova 470 mm in height. In width, the Mova reaches 420 mm, the Roborock 381 mm and the Dreame 340 mm. It's advisable to measure available space before deciding, especially if the base goes under furniture or in a tight space.
Real-World Usage Experience
For homes with long-haired pets, all three anti-tangle brush systems work well, although the dual HyperStream brush of the Dreame and Mova makes manual maintenance somewhat easier. The Mova V50 Ultra's extra power can be noticeable on medium-pile carpets or in homes where sand or coarse dirt accumulates.
In large homes, the 220-minute autonomy of the Mova V50 Ultra and the 200 of the Dreame L50 Pro Ultra offer greater margin than the 180 of the Roborock Saros 10R. If the surface exceeds 200 m², the Mova minimises intermediate recharges. Water tank capacity also influences: the Dreame with 4.5 litres of clean water allows longer mopping sessions without intervention.
The Roborock Saros 10R stands out for its reduced height of 79.8 mm, a key aspect if you have low furniture or beds with little clearance. Its mop lift up to 22 mm also exceeds the other two, an advantage in homes with short-pile carpets you want to protect from water.
If you're looking for the most intensive mopping, the Mova V50 Ultra with hot water for the floor, UV disinfection and dual detergent tank offers the most complete equipment. For those who value the reliability of an established brand and a refined navigation system, the Roborock Saros 10R represents the most proven option. The Dreame L50 Pro Ultra balances features and offers the possibility of adding the plumbing connection kit later.
Conclusion: Which to Choose?
Choose the Dreame L50 Pro Ultra if you're looking for balance between power, autonomy and tank capacity, especially if you value having 4.5 litres of clean water for long mopping sessions. The possibility of adding the plumbing connection kit may interest you if you prefer not to refill manually. Its base is the tallest, an aspect to consider depending on available space.
Choose the Roborock Saros 10R if you need a low robot that accesses under furniture with less than 8 cm of clearance. Its mop lift up to 22 mm better protects carpets and the StarSight 2.0 system offers the most refined navigation of the three. It's the most compact option in base and robot height, ideal for tight spaces.
Choose the Mova V50 Ultra if you prioritise maximum suction power (24,000 Pa), greater autonomy (220 minutes) and the most complete mopping equipment with hot water for the floor, UV disinfection and dual detergent tank. Its ability to recognise up to 200 obstacles makes it especially suitable for homes with many objects on the floor or young children. The base is the widest but the shortest of the three.
