Introduction
Dreame presents two proposals within its high-end range of robot vacuum cleaners with multifunction base: the L10s Ultra Gen 2, launched in 2024, and the L50s Pro Ultra from 2026. Although they share the same comprehensive cleaning philosophy with rotating mops and self-washing station, the technical differences between them are considerable and mark two distinct generations in terms of artificial intelligence, power and navigation capabilities.
The L10s Ultra Gen 2 is positioned as a solid option for those seeking a complete robot without complications, whilst the L50s Pro Ultra incorporates more advanced technology with dual AI camera, greater suction power and intelligent functions that bring it closer to the most sophisticated models on the market. Both are designed for homes that require frequent mopping, although the second model raises the performance for more demanding users.
Power and Suction
The most striking difference in this section is the suction power. The Dreame L10s Ultra Gen 2 reaches 10,000 Pa, a respectable figure for most domestic situations. However, the Dreame L50s Pro Ultra triples this figure with its 30,000 Pa, which represents an enormous leap in suction capacity, especially useful on thick carpets or when there are pets at home.
The brushing system also evolves notably. The 2024 model features a simple silicone brush, effective at reducing hair tangles but without specific anti-tangle technology. The L50s Pro Ultra incorporates the dual HyperStream brush, specifically designed to prevent hair from tangling thanks to its two brushes anchored at one end. This system makes a real difference in homes with long-haired pets.
Additionally, the L50s Pro Ultra lifts the main brush during mopping, something the L10s Ultra Gen 2 does not do. This prevents the brush from getting unnecessarily wet and improves efficiency in mopping mode.
As for the side brush, only the most recent model makes it extendable and liftable, which improves cleaning in corners and prevents it from dragging dirt when mopping. The side brush of the L50s Pro Ultra also features anti-tangle technology, absent on the L10s Ultra Gen 2.
Mopping
Both robots use the system of two rotating mops at 180 RPM with RoboSwing movement, which allows the mops to extend under overhangs and furniture. Mop lifting is also identical on both: 10.5 mm, sufficient to pass over thin carpets without wetting them.
The big difference is in the washing of the mops. The Dreame L10s Ultra Gen 2 washes the mops with cold water, whilst the Dreame L50s Pro Ultra does so with hot water at 100°C. This not only improves sanitisation, but also removes difficult stains and grease residue better. In practice, hot water makes a difference when mopping kitchen floors or areas with greater accumulated dirt.
The L50s Pro Ultra adds dirt detection on both the mops and the floor, something the previous model does not have. This allows the robot to identify particularly dirty areas and automatically go over them again or rewash the mops. It can also remove the mops at the base to perform pure vacuuming tasks without dragging them, a function absent on the L10s Ultra Gen 2.
Mop drying is identical on both: hot air at 45°C, effective at preventing bad odours and bacterial growth.
Navigation System
Both models integrate 360° LiDAR turret and front 3D laser sensor to detect obstacles. However, the Dreame L50s Pro Ultra incorporates dual AI camera, whilst the L10s Ultra Gen 2 lacks a camera. This represents a radical change in recognition capability.
The 2026 model recognises up to 220 different obstacles, compared to the L10s Ultra Gen 2 for which no exact number is specified. The dual camera allows remote access for surveillance, a function that can be useful if you want to monitor pets or the home from outside. Additionally, the L50s Pro Ultra features night vision LED, which improves recognition in low-light conditions.
Pet recognition is present on both, but only the L50s Pro Ultra detects curtains, avoiding getting tangled in them. Artificial intelligence also takes a leap: CleanGenius 2.0 on the 2024 model versus CleanGenius 3.0 on the 2026 one. The latter includes AI stain recognition, absent on the L10s Ultra Gen 2.
Autonomy and Battery
Battery capacity is identical: 5,200 mAh on both robots. The Dreame L10s Ultra Gen 2 offers 240 minutes of autonomy, a figure more than sufficient for medium-large sized homes. For the L50s Pro Ultra, no specific autonomy data in minutes is available, although with the same battery and greater suction power, it is likely to consume more in maximum mode.
In any case, as these are robots with multifunction base that automatically return to charge, autonomy is not usually a limiting factor except in very extensive homes.
Intelligent Functions
The Dreame L10s Ultra Gen 2 can overcome obstacles up to 20 mm in height. The Dreame L50s Pro Ultra improves this figure: 22 mm on single thresholds and up to 40 mm on double thresholds, which notably expands its ability to move between rooms with uneven levels or pass more pronounced thresholds.
An exclusive function of the L50s Pro Ultra is its own voice assistant, which allows direct interaction with the robot without needing to use the app or external assistants. Both models are compatible with Alexa and Google Home.
Multifunction Cleaning Base
Both bases feature auto-emptying of the dust container, washing and drying of mops, and detergent tank. Tank capacities are identical: 3.2-litre dust bag, 4.5 litres of clean water and 4 litres of dirty water. Both models also offer an optional plumbing connection kit, although it must be purchased separately.
The main difference is in the self-cleaning of the washing tray. The Dreame L50s Pro Ultra integrates third-generation self-cleaning, whilst the L10s Ultra Gen 2 does not have this function. This reduces manual maintenance of the base and improves long-term hygiene.
As already mentioned, mop washing with hot water at 100°C is exclusive to the most recent model, which represents an important bonus in hygiene and cleaning effectiveness.
Dimensions
The diameter is identical on both robots: 350 mm. Height varies slightly: 97 mm on the L10s Ultra Gen 2 versus 103.8 mm on the L50s Pro Ultra. Although the difference is less than a centimetre, it may be relevant if you need the robot to pass under very low furniture.
The bases have practically identical dimensions: 340 mm wide, around 590 mm high and 457 mm deep. They occupy similar space and require the same location in the home.
The robot's dust container is slightly larger on the L10s Ultra Gen 2 (300 ml versus 250 ml), although this has little practical relevance as both have auto-emptying. The water tank is identical: 80 ml.
Real-world usage experience
For medium-sized homes without pets or with short-haired pets, the Dreame L10s Ultra Gen 2 offers complete performance. Its 10,000 Pa power is sufficient for hard floors and thin carpets, and the rotating mop system with RoboSwing covers daily mopping well. The absence of an AI camera is not a problem if the home layout is simple and there are not many small obstacles.
The Dreame L50s Pro Ultra is designed for more demanding users or complex homes. The 30,000 Pa power makes a real difference on thick carpets or when there is accumulated pet hair. The dual HyperStream brush drastically reduces maintenance in homes with long-haired dogs or cats. The dual AI camera and 220 obstacle recognition improve navigation in spaces with many objects on the floor or low furniture.
Mop washing with hot water at 100°C is especially useful in kitchens or areas where grease accumulates. Dirt detection allows the robot to adapt its cleaning without manual intervention, something that saves time and improves results.
The ability to overcome double thresholds up to 40 mm opens up possibilities in homes with more pronounced uneven levels, something the L10s Ultra Gen 2 cannot tackle with the same ease.
Conclusion: Which one to choose?
Choose the Dreame L10s Ultra Gen 2 if you are looking for a complete robot at a more competitive price, your home does not have complicated uneven levels or many small obstacles, you do not have long-haired pets or the amount of hair is not excessive, and you do not need remote camera access or advanced AI functions. It is a solid option for those who want to forget about mopping and vacuuming without complications.
Choose the Dreame L50s Pro Ultra if you have long-haired pets and want to minimise brush maintenance, you need maximum suction power for thick carpets or very dirty floors, you value deep sanitisation with hot water at 100°C, you want remote camera access for surveillance, your home has pronounced uneven levels or double thresholds, and you are looking for maximum artificial intelligence with dirt detection and advanced obstacle recognition. It is the robot for those seeking the most complete on the market without compromises.
