Introduction
The Dreame L40s Pro Ultra, the Dreame L50 Pro Ultra and the Mova P50 Ultra represent Dreame's commitment for 2025 in the premium robot vacuum segment. All three models share a similar architecture with a multifunction base that washes and dries the mops with hot water and air, as well as performing auto-emptying of the dust bin. We're talking about devices designed for users seeking complete autonomous cleaning, both in vacuuming and mopping.
Suction power is around 19,000 Pa in all three cases, figures more than sufficient for homes with pets or carpets. All incorporate advanced navigation systems and extendable side brushes to improve sweeping in corners. However, the differences between them are not insignificant: the L50 Pro Ultra stands out for its retractable LiDAR and greater battery capacity, whilst the Mova P50 Ultra presents itself as a more streamlined alternative in features and price.
Power and Suction
The Dreame L50 Pro Ultra leads in raw power with 19,500 Pa, an advantage of 500 Pa over the L40s Pro Ultra and the Mova P50 Ultra. In practice, this difference can be noticed on high-pile carpets or when there is significant accumulation of ingrained dirt. All three devices feature an extendable and liftable side brush, which allows better sweeping of corners and lifting it when mopping to prevent it getting wet.
Where a structural difference does appear is in the main brush. The L40s Pro Ultra and the L50 Pro Ultra integrate a HyperStream dual brush system, designed specifically to reduce tangles from long hair. The Mova P50 Ultra features a single brush, probably silicone or similar, but without the dual architecture. For homes with pets or people with long hair, this makes a difference in weekly maintenance.
All three models lift the main brush during mopping, preventing it from getting wet and dragging damp dirt around the house. Additionally, all incorporate anti-tangle technology in both the main and side brushes. This considerably simplifies maintenance and reduces the need to cut hair with scissors every few weeks.
Mopping
The mopping system is practically identical in all three robots: two rotating mops with side extension and Roboswing movement, which allows the robot to slightly insert the mops under furniture or overhangs. Mop lifting reaches 10.5 mm in all cases, sufficient to pass over thin carpets without wetting them. All mop with cold water, both on the floor and when washing mops at the base.
This is where an important functional difference appears. The Dreame L40s Pro Ultra and the L50 Pro Ultra automatically detach the mops at the base when you only want to vacuum, preventing you from dragging them around the house unnecessarily. The Mova P50 Ultra does not have this function, which requires manually removing them if you only need to vacuum. Nor does it incorporate dirt detection on the mops or floor, something that the two Dreame models do include to automatically re-mop dirtier areas.
All three bases wash the mops with hot water and dry them with hot air, which speeds up drying and prevents bad odours. Self-cleaning of the washing tray is present in all three models, with third-generation technology. This considerably reduces manual maintenance of the base.
Navigation System
The Dreame L50 Pro Ultra incorporates a retractable LiDAR that hides inside the robot's body, reducing its total height to 89 mm. This allows it to slip under low furniture where the L40s Pro Ultra, with its traditional 103.8 mm turret, cannot enter. The Mova P50 Ultra measures 97 mm, a middle ground but with a fixed turret. For homes with low sofas or beds with little space, the L50 Pro Ultra is clearly superior.
Both Dreame models feature dual AI camera capable of recognising up to 180 different types of obstacles, including pets, cables, slippers or toys. The Mova P50 Ultra has no camera, which limits its ability to recognise small objects. All have a front 3D laser sensor to avoid collisions, but the camera adds an extra layer of intelligence.
Remote camera access is only available on the L40s Pro Ultra and the L50 Pro Ultra, allowing you to monitor the home from the app. Both include a front LED for night vision, useful if the robot cleans at night or in dark areas. The Mova P50 Ultra lacks these functions, focusing on more basic though effective navigation.
All three devices recognise curtains and adjust their behaviour to avoid getting trapped. Intelligent cleaning with CleanGenius technology is present in all, optimising routes and cleaning modes according to the type of floor detected.
Autonomy and Battery
The Dreame L50 Pro Ultra features a 6,400 mAh battery, much superior to the 5,200 mAh of the L40s Pro Ultra and the Mova P50 Ultra. Curiously, its declared autonomy is 200 minutes, slightly lower than the L40s's 220 minutes. This is probably because the L50 Pro Ultra manages more suction power and additional systems such as the retractable LiDAR.
In any case, we're talking about extensive autonomies that allow cleaning homes of over 150 square metres in a single charge. If the battery runs out, all three robots automatically return to the base, recharge as necessary and continue where they left off. For flats of less than 100 square metres, the battery difference will not be decisive.
Smart Functions
The ability to overcome obstacles is similar: single steps of up to 22 mm on the Mova P50 Ultra, and the same height on both Dreame models although with less specific description. This allows navigating thick carpets or small level changes between rooms without getting stuck.
The Dreame L40s Pro Ultra and the L50 Pro Ultra include their own voice assistant, which allows giving them commands directly without needing to use the mobile. All three are compatible with Alexa and Google Home, but having an integrated assistant adds convenience in day-to-day use. The Mova P50 Ultra does not have this function.
Multifunction Cleaning Base
All three bases perform auto-emptying of the dust bin into a 3.2-litre bag, sufficient for several weeks without changing it. Mop washing is done with hot water and drying with hot air in all cases, guaranteeing hygiene and speed. Third-generation self-cleaning of the washing tray is present in all three models, reducing manual maintenance.
The clean water tank is 4.5 litres in both Dreame models and 4 litres in the Mova. The dirty water tank is 4 litres in the Dreame models and 3.5 litres in the Mova. Small differences that in practice don't affect too much, although large homes will appreciate those extra 500 ml.
The detergent tank is integrated in the L40s Pro Ultra and the L50 Pro Ultra, automatically dispensing during mop washing. In the Mova P50 Ultra it is optional, which means it must be purchased separately if you want to use detergent. It's not a critical factor, but it is a convenience detail.
Both the L40s and the L50 Pro Ultra offer an optional plumbing connection kit, which is purchased separately. The Mova P50 Ultra does not have this option. It's an accessory for users who prefer not to refill tanks manually, although it's not something that comes as standard nor should it weigh too heavily in the purchase decision.
Dimensions
The Dreame L50 Pro Ultra is the lowest at 89 mm in height thanks to its retractable LiDAR, a clear advantage for passing under furniture. The Mova P50 Ultra measures 97 mm and the L40s Pro Ultra reaches 103.8 mm. If you have sofas or beds with less than 10 cm of clearance, the L50 Pro Ultra is the only viable option.
The diameter is identical in all three: 350 mm. The differences are in the bases. The Mova P50 Ultra has a wider base (420 mm compared to 340 mm) but less tall (470 mm compared to 590.5 mm). This can facilitate its placement under worktops or in spaces with little height, although it occupies more horizontal space.
Real-World User Experience
For large homes, the Dreame L50 Pro Ultra offers the best combination of extensive battery, larger dust bin and slightly superior power. Its ability to slip under low furniture is a plus if your home's layout requires it. The L40s Pro Ultra is very similar in features, with the advantage of the dual AI camera and remote access, ideal if you value surveillance or have pets and want to see them from the app.
The Mova P50 Ultra positions itself as a more economical alternative, sacrificing advanced AI functions, camera and some conveniences such as automatic mop detachment. It remains a very capable robot, especially in basic vacuuming and mopping, but requires more manual intervention. Its more compact base in height can be advantageous in certain spaces.
If you have pets, the two Dreame models with HyperStream dual brush and AI pet recognition are more advisable. The Mova P50 Ultra, with its single brush and no camera, may require more maintenance and will not avoid obstacles such as toys or feeding bowls as well.
Conclusion: Which to Choose?
Choose the Dreame L40s Pro Ultra if you're looking for a balance between advanced features and moderate height, you value remote camera access for surveillance and don't need to slip under extremely low furniture. Its 220-minute autonomy and dual AI camera make it very versatile for homes with pets and children.
Choose the Dreame L50 Pro Ultra if you have low furniture and need a robot that can pass underneath without problems. Its retractable LiDAR, 6,400 mAh battery and 395 ml dust bin make it the most complete option for large homes. The slight advantage in suction power also counts if you have thick carpets.
Choose the Mova P50 Ultra if you're looking for a more budget-friendly option and don't need advanced AI functions such as pet recognition or remote camera access. Its more compact base in height can be useful if available space requires it. You'll have to manually detach the mops when you only want to vacuum, but it still offers good performance in basic cleaning.
