Introduction
Dreame presents three high-end proposals launched in 2025 that compete directly with each other within its own catalogue. The Dreame L10s Ultra Gen 3, launched in November 2025, the Dreame L40 Ultra AE and the Dreame X50 Ultra Blanca represent three levels of equipment and features that can adapt to different needs and budgets.
All three models feature a complete multifunction base, which guarantees efficient mopping with washing and drying of mops. However, differences in suction power, navigation systems and intelligent functions mark significant distances between them. The L10s Ultra Gen 3 stands out for its raw power, whilst the X50 Ultra Blanca incorporates the brand's most advanced technologies. The L40 Ultra AE sits at an intermediate point with interesting features for those seeking balance.
Power and Suction
The Dreame L10s Ultra Gen 3 clearly leads in suction power with 25,000 Pa, a figure that far exceeds the 19,000 Pa of the L40 Ultra AE and the 20,000 Pa of the X50 Ultra Blanca. This difference can be particularly noticeable on thick carpets or when there is significant dirt accumulation.
Regarding the brushing system, the differences are significant. The L10s Ultra Gen 3 is equipped with a SimpliCut brush, whilst the L40 Ultra AE incorporates the TriCut 3.0, designed to reduce hair tangles through integrated blades. The X50 Ultra Blanca opts for a dual brush that improves dirt collection.
Main brush lifting during mopping is present in the L40 Ultra AE and the X50 Ultra Blanca, but not in the L10s Ultra Gen 3. This allows the former to prevent the brush from touching the wet floor and getting unnecessarily dirty. The X50 Ultra Blanca goes further: it also lifts the side brush during mopping and features anti-tangle technology on this side brush, something exclusive to this model.
The extendable side brush of the L10s Ultra Gen 3 and the X50 Ultra Blanca improves corner cleaning, a function that the L40 Ultra AE does not have. For homes with many corners or complicated skirting boards, this is worth considering.
Mopping
All three robots employ a system of two rotating mops with side extension and Roboswing movement, which allows better reach of edges and slightly inserting the mops under furniture overhangs. Mop lifting is identical in all three: 10.5 mm, sufficient to climb onto thin carpets without wetting them.
The floor mopping water is cold in all three models. However, the base washes the mops with hot water in all of them, which facilitates the removal of adhered dirt. Drying is also carried out with hot air, preventing bad odours and bacterial proliferation.
An important difference: the X50 Ultra Blanca can automatically detach the mops at the base when you only want to vacuum. This avoids having to do it manually and allows more versatile cleaning sessions. Neither the L10s Ultra Gen 3 nor the L40 Ultra AE offer this function.
Dirt detection on mops and on the floor is present in the L40 Ultra AE and the X50 Ultra Blanca, allowing the robot to rewash the mops or re-mop particularly dirty areas. The L10s Ultra Gen 3 lacks this capability, which may result in less precise mopping results on difficult stains.
Regarding self-cleaning of the washing tray, the L10s Ultra Gen 3 and the X50 Ultra Blanca feature the third generation of this system, whilst the L40 Ultra AE has the second generation. The difference in practice may be noticeable in the frequency of manual maintenance required.
Navigation System
Here the differences are notable. The Dreame L10s Ultra Gen 3 has a traditional LiDAR turret and front 3D laser sensor, but does not include an AI camera. This limits its object recognition capabilities and does not allow remote camera access or night vision with LED.
The L40 Ultra AE incorporates LiDAR turret, front 3D sensor and AI camera, which allows it to recognise up to 120 types of obstacles. Additionally, it features front LED for night vision and remote camera access, useful for basic home surveillance.
The X50 Ultra Blanca represents the highest level: retractable LiDAR that reduces the robot's height, dual AI camera and capability to recognise up to 200 different obstacles. It also incorporates specific curtain detection, something the other two models do not have. The AI Sage 13.0 processor with 9 TOPS NPU makes the difference in processing speed and mapping precision.
All three models recognise pets and feature the CleanGenius system for intelligent AI-powered cleaning, although the depth of analysis varies according to each unit's capabilities. Only the X50 Ultra Blanca adds AI stain recognition.
Autonomy and Battery
The Dreame X50 Ultra Blanca is equipped with a 6,400 mAh battery that gives it 180 minutes of autonomy. It is a solid figure for large homes, although curiously lower than the 231 minutes of the L10s Ultra Gen 3 with its 5,200 mAh battery. This difference may be due to the higher consumption of the AI systems and dual camera of the X50.
The L40 Ultra AE has the same 5,200 mAh battery as the L10s Ultra Gen 3, but its autonomy in minutes is not specified. In practice, all three models have sufficient capacity to clean homes of over 200 square metres in a single session.
Intelligent Functions
All three robots can overcome obstacles of 20 mm in height, except the X50 Ultra Blanca which climbs simple steps without specifying exact height, which suggests improved capabilities in this aspect.
The Dreame X50 Ultra Blanca incorporates its own voice assistant, in addition to compatibility with Alexa and Google Home. The other two models only work with external assistants. This can make a difference for those who prefer voice control without depending on third-party ecosystems.
Multifunction Cleaning Base
All three models feature a complete multifunction base: auto-emptying, hot water washing and hot air drying of mops. The tank capacities are identical: 3.2-litre dust bag, 4.5-litre clean water tank and 4-litre dirty water tank.
All include a detergent tank and have an optional plumbing connection kit available, although none comes with the connection integrated as standard. This kit is purchased separately and can be convenient for those who prefer not to manually refill the tanks.
The most relevant difference: the X50 Ultra Blanca incorporates UV disinfection of the base, something that neither the L10s Ultra Gen 3 nor the L40 Ultra AE offer. This helps maintain the hygiene of the cleaning station in the long term.
Dimensions
The diameter is identical in all three: 350 mm. The robot's height varies slightly: 97 mm in the L10s Ultra Gen 3 and the L40 Ultra AE, versus 89 mm of the X50 Ultra Blanca. These 8 mm of difference can be decisive for passing under low furniture or beds with little clearance from the floor.
The base dimensions are practically the same, with minimal variations of millimetres that do not affect the space required to install them. All require approximately the same space: 340 mm wide, 590 mm high and 457 mm deep.
The robot's dust bin is 300 ml in the L10s Ultra Gen 3 and 395 ml in the other two models. This difference may be noticeable in very intensive cleaning sessions before auto-emptying, although in practice all three empty automatically at the base.
Real-World Experience
For large homes, the X50 Ultra Blanca offers the largest battery and autonomy combined with more precise navigation thanks to its dual camera and retractable LiDAR. The L10s Ultra Gen 3 compensates with greater declared autonomy and superior suction power, ideal if there are thick carpets or large hard surface areas with frequent dirt.
In homes with pets, all three models recognise animals, but the anti-tangle side brush of the X50 Ultra Blanca makes a difference. The TriCut 3.0 of the L40 Ultra AE also helps reduce hair tangles. The L10s Ultra Gen 3, with its SimpliCut brush, may require somewhat more manual maintenance.
The absence of a camera in the L10s Ultra Gen 3 limits its small object recognition capabilities and does not allow remote surveillance. For those who value these functions, the L40 Ultra AE or the X50 Ultra Blanca are more complete options.
The automatic mop detachment of the X50 Ultra Blanca is particularly convenient if you frequently alternate between vacuum-only sessions and complete mopping. The other two models require manual intervention to remove the mops.
