Introduction
The Dreame L50 family features three models that share a surname but hide important technical differences. The Dreame L50 Pro Ultra and the Dreame X50 Ultra Blanca arrived in 2025, whilst the Dreame L50s Pro Ultra appeared a year later, in 2026. All three units feature a complete multifunction base: automatic dust emptying, hot water mop washing and hot air drying. These are robots designed for those seeking total automation of mopping and vacuuming, with the capacity to adapt to medium and large homes thanks to their 4.5-litre clean water and 4-litre dirty water tanks.
All include dual HyperStream brushes, a system that minimises hair tangles, something especially useful in homes with pets. The rotating mops extend to reach edges and corners, and automatically detach at the base when only vacuuming is needed. Navigation with dual AI cameras and front 3D laser sensor allows them to avoid obstacles with precision.
Power and Suction
Suction power marks the most notable difference between these three models. The Dreame L50s Pro Ultra leads with 30,000 Pa, a figure that far exceeds the 19,500 Pa of the L50 Pro Ultra. The X50 Ultra Blanca sits at an intermediate point with 20,000 Pa. This difference can be particularly noticeable on thick carpets or when there is accumulated dirt embedded in floor joints.
All three feature dual HyperStream brushes, a design that significantly reduces long hair tangles by having each brush anchored at one end. This system is especially practical in homes with pets or people with long hair, where maintenance is considerably simplified. The main brush can be raised during mopping, preventing it from getting unnecessarily wet.
The side brush also raises in mopping mode and features an extendable function to better reach corners. All three models share these characteristics, which guarantees effective sweeping in the most difficult corners. Additionally, the side brush incorporates anti-tangle technology.
Mopping
The mopping system is practically identical across all three robots. All use two rotating mops that extend to reach edges, accompanied by the Roboswing system that allows the robot to make a lateral movement to get the mops under furniture or overhangs. Mop lift reaches 10.5 mm in all three cases, sufficient to overcome thin carpets without wetting them.
The mops are washed at the base with hot water, which improves the removal of grease and adhered dirt. Drying is also carried out with hot air, speeding up the process and preventing the proliferation of bacteria or bad odours. The self-cleaning of the washing tray is third generation in all three models, which reduces manual maintenance.
All detect dirt both on the mops and on the floor, adjusting mopping intensity or repeating passes over dirtier areas. The mops can automatically detach at the base when only vacuuming is needed, avoiding dragging them unnecessarily around the home. The water used for mopping the floor is cold in all three cases.
Navigation System
Here an important structural difference appears. The Dreame L50 Pro Ultra and the X50 Ultra Blanca have retractable LiDAR, which reduces the total height of the robot to 89 mm and makes it easier to pass under low furniture. The L50s Pro Ultra, on the other hand, uses a traditional LiDAR turret that raises its height to 103.8 mm. This may limit its access under some sofas, beds or furniture with little clearance from the floor.
Object recognition capacity varies between the three. The L50s Pro Ultra identifies up to 220 different objects, the X50 Ultra Blanca recognises 200 and the L50 Pro Ultra remains at 180. In practice, this means that the 2026 model can distinguish with greater precision cables, toys, slippers or other elements it must avoid.
All three have dual AI cameras, front 3D laser sensor and LED for night vision. They recognise pets, detect curtains and allow remote access to the camera from the app. The CleanGenius algorithm with AI is present in all, optimising routes and adjusting cleaning according to the type of dirt detected. The L50 Pro Ultra and the X50 Ultra Blanca use the AI Sage 13.0 processor, although the chip of the L50s Pro Ultra is not specified.
Runtime and Battery
The Dreame L50 Pro Ultra and the X50 Ultra Blanca share a 6,400 mAh battery, whilst the L50s Pro Ultra reduces this capacity to 5,200 mAh. However, the 2026 model does not specify minutes of runtime, which makes a direct comparison in this aspect difficult.
The L50 Pro Ultra offers 200 minutes of continuous operation, sufficient to cover large homes in a single session. The X50 Ultra Blanca reaches 180 minutes, a figure also ample for most homes. The 20-minute difference may be noticeable in houses of more than 150 square metres with several programmed cleaning levels.
Despite the lower battery capacity of the L50s Pro Ultra, its superior suction power could imply higher energy consumption, although this cannot be confirmed without specific runtime data.
Smart Features
All three robots can overcome simple steps, which allows them to move between rooms with small level changes or pass from hard floors to carpets with raised edges. None incorporates a robotic arm.
All include their own voice assistant and compatibility with Alexa and Google Home, allowing them to be controlled by voice commands without needing to open the app. This feature is convenient for starting quick cleans or sending the robot to a specific room whilst carrying out other tasks.
Multifunction Cleaning Base
The multifunction base is practically identical across all three models. All feature automatic emptying of the dust bin, hot water mop washing and hot air drying. The dust bag has a capacity of 3.2 litres, sufficient for several weeks without changing it in medium-sized homes.
The clean water tanks reach 4.5 litres and the dirty water tanks 4 litres, allowing large surfaces to be mopped without manual intervention. The self-cleaning of the washing tray is third generation in all, reducing the need to clean it manually frequently.
The Dreame X50 Ultra Blanca differs by incorporating UV disinfection, a function that eliminates bacteria on the mops after washing. The other two models do not include this technology.
All three have a detergent tank and offer an optional plumbing connection kit that is purchased separately, although none comes with this connection integrated from the factory.
Dimensions
The diameter is identical in all three: 350 mm. The height, on the other hand, marks a relevant functional difference. The L50 Pro Ultra and the X50 Ultra Blanca measure 89 mm tall, whilst the L50s Pro Ultra reaches 103.8 mm due to its traditional LiDAR turret. This difference of almost 15 mm can determine whether or not the robot passes under certain furniture.
The dimensions of the base are practically the same: 340 mm wide, around 590 mm tall and approximately 457 mm deep. It's advisable to reserve an accessible space for the base, as the robot returns several times during mopping to wash the mops.
Real-World Experience
For homes with pets, all three models work well thanks to the dual HyperStream brush that prevents tangles. The 30,000 Pa power of the L50s Pro Ultra can make a difference on carpets where embedded hair accumulates. The L50 Pro Ultra and the X50 Ultra Blanca, with 19,500 Pa and 20,000 Pa respectively, also offer solid results on hard floors and short-pile carpets.
In large homes, the 200-minute runtime of the L50 Pro Ultra and the 180 minutes of the X50 Ultra Blanca guarantee that the robot completes cleaning without needing to recharge mid-session. The L50s Pro Ultra, with its 5,200 mAh battery, might require intermediate recharging on very large surfaces, although specific runtime data is not available.
If there is low furniture, the L50 Pro Ultra and the X50 Ultra Blanca have a clear advantage with their 89 mm height. The L50s Pro Ultra, at 103.8 mm, may be left out of some spaces. This is worth considering especially if you have a bed with a low storage base or sofas with little clearance from the floor.
Mopping is effective in all three thanks to hot water washing and hot air drying. Dirt detection makes them repeat passes over more stained areas, something useful in kitchens or high-traffic areas. The X50 Ultra Blanca adds UV disinfection, which can provide additional peace of mind in homes with young children or people with allergies.
Conclusion: Which to Choose?
Choose the Dreame L50 Pro Ultra if you're looking for a balance between power, runtime and reduced height. Its 200 minutes of operation and 89 mm height make it ideal for large homes with low furniture. The power of 19,500 Pa is sufficient for most homes without very thick carpets. Its 395 ml dust bin reduces maintenance frequency.
Choose the Dreame L50s Pro Ultra if suction power is a priority. With 30,000 Pa and capacity to recognise up to 220 objects, it is the most advanced in these aspects. However, its height of 103.8 mm and 5,200 mAh battery may be limitations in homes with low furniture or very large surfaces. The 250 ml dust bin also requires more frequent emptying.
Choose the Dreame X50 Ultra Blanca if you value UV disinfection and want to maintain a balance similar to the L50 Pro Ultra. With 20,000 Pa of power, 180 minutes of runtime and 89 mm height, it offers very comprehensive features. UV disinfection in the base can be a deciding factor if there is particular concern about mop hygiene. Its capacity to recognise 200 objects places it at an intermediate point between the other two models.
