Introduction
Choosing between these three models can be tricky, especially when two of them share the same manufacturer. The Mova E40 Ultra, the Dreame L10s Ultra Gen 3 and the Dreame L40 Ultra AE are robots launched in 2025 that incorporate a complete multifunctional base: auto-emptying, mop washing with hot water and drying with hot air. All feature LiDAR laser navigation system and rotating mops with side extension to improve edge mopping.
The fundamental difference lies in the artificial intelligence and some equipment details that can make a difference to the user experience. Whilst the Mova E40 Ultra and the Dreame L10s Ultra Gen 3 are positioned as more accessible options, the Dreame L40 Ultra AE incorporates an AI camera and advanced functions that place it a step above. The choice will depend on the level of automation you're looking for and whether you need specific features such as greater suction power or intelligent dirt detection.
Power and Suction
Suction power marks a notable difference. The Dreame L10s Ultra Gen 3 reaches 25,000 Pa, a figure that makes it the most powerful of the three. This can translate into better pickup of ingrained dirt on carpets or in parquet grooves. The Mova E40 Ultra and the Dreame L40 Ultra AE remain at 19,000 Pa, a figure that is still competent for most homes but which may fall short if you have long-pile carpets or pets that shed a lot of hair.
As for brushes, the Dreame L40 Ultra AE incorporates the TriCut 3.0 system, which combines bristles with blades designed to cut tangled hair. This model can also raise the main brush during mopping, preventing wet dirt from adhering to the bristles. The Mova E40 Ultra and the Dreame L10s Ultra Gen 3 mount the SimpliCut brush, more basic and without lifting capability.
The side brush presents interesting variations. The Dreame L10s Ultra Gen 3 features an extendable side brush, useful for better sweeping corners by projecting outwards. The Mova E40 Ultra opts for an anti-tangle side brush, a feature that the Dreame models don't have and which is practical if you live with long-haired pets. None of the three can raise the side brush during mopping.
Mopping
All three models use two rotating mops with side extension and Roboswing movement, a system that allows the robot to make a slight lateral movement to get the mops under furniture and overhangs. Mop lifting is identical on all three: 10.5 mm, sufficient to pass over thin carpets without wetting them.
The base washes the mops with hot water in all three cases and dries them with hot air, essential functions for keeping mops clean and avoiding bad odours. Here a difference appears: the Dreame L10s Ultra Gen 3 incorporates third-generation tray self-cleaning, whilst the Dreame L40 Ultra AE has the second generation. The Mova E40 Ultra doesn't include this function, which means you'll have to manually clean the washing tray more frequently.
The Dreame L40 Ultra AE takes a step forward with dirt detection. This model analyses both the mops and the floor during mopping, identifying dirtier areas for re-scrubbing or rewashing the mops if necessary. In practice, this translates into more efficient mopping without manual intervention. The Mova E40 Ultra and the Dreame L10s Ultra Gen 3 lack this function.
All three mop with cold water from the robot's tank. None automatically removes the mops at the base when you only want to vacuum, you'll have to do it manually if you don't wish to mop.
Navigation System
All mount a LiDAR turret for mapping and a front 3D laser sensor to avoid obstacles. They recognise pets and feature CleanGenius artificial intelligence to optimise cleaning routes.
The big difference is in the Dreame L40 Ultra AE, which adds an AI camera capable of recognising up to 120 types of obstacles. This camera includes a night vision LED to function in low-light conditions and allows remote access, so you can see what the robot is doing from the app or even use it as a surveillance camera when you're not at home. The Mova E40 Ultra and the Dreame L10s Ultra Gen 3 don't have a camera or front LED.
For homes with many objects on the floor, cables or toys, the Dreame L40 Ultra AE's camera makes the difference. The other two models perform well with the 3D laser sensor, but don't reach the same level of precision in recognising small objects.
Autonomy and Battery
Battery capacity is 5,200 mAh on all three models. The Mova E40 Ultra declares 210 minutes of autonomy, whilst the Dreame L10s Ultra Gen 3 reaches 231 minutes. The Dreame L40 Ultra AE doesn't specify autonomy in minutes, although it shares the same battery.
That 21-minute difference between the Mova E40 Ultra and the Dreame L10s Ultra Gen 3 may be due to software optimisations or the consumption of the latter's greater suction power. In any case, both offer sufficient autonomy for large homes, being able to cover more than 200 square metres on a single charge if working in standard mode.
Smart Functions
All three can overcome obstacles up to 20 mm in height, useful for passing thresholds or small level differences between rooms. None incorporates a robotic arm or its own voice assistant, although all are compatible with Alexa and Google Home for external voice control.
CleanGenius intelligence is present in all three, managing cleaning routes and adjusting parameters according to floor type or detected dirt level. The Dreame L40 Ultra AE makes better use of this AI thanks to the camera, which provides additional visual information.
Multifunctional Cleaning Base
All three bases offer auto-emptying of the dust bin with a 3.2-litre bag, mop washing with hot water and drying with hot air. The water tanks are identical: 4.5 litres of clean water and 4 litres of dirty water.
The detergent tank comes included with the Dreame L10s Ultra Gen 3 and the Dreame L40 Ultra AE, whilst on the Mova E40 Ultra it's optional, something to bear in mind if you value the convenience of the base automatically adding detergent during mop washing. Both Dreame models offer a plumbing connection kit as an optional accessory, eliminating the need to manually refill and empty tanks. This kit is purchased separately and doesn't come as standard.
Tray self-cleaning differentiates the Dreame L10s Ultra Gen 3, with third generation, from the Dreame L40 Ultra AE, with second generation. The Mova E40 Ultra doesn't include this function, which means more manual maintenance. None incorporates UV disinfection or automatic mop changing.
Dimensions
All three robots share dimensions: 350 mm in diameter and 97 mm in height. They can slip under low furniture without problems, although it's advisable to measure beforehand if you have sofas or beds very close to the floor.
The bases are also practically identical. The Mova E40 Ultra and the Dreame L40 Ultra AE measure 340 mm wide, 590.5 mm high and 456.7 mm deep. The Dreame L10s Ultra Gen 3 has 590 mm height and 457 mm depth, millimetric differences without practical relevance. All require considerable space, especially in depth.
Robot Tanks
The Dreame L40 Ultra AE incorporates a dust bin in the robot of 395 ml, larger than the 300 ml of the Mova E40 Ultra and the Dreame L10s Ultra Gen 3. This can be useful if you use the robot away from home or in a second home without a base, although in normal use the auto-emptying makes this difference of little relevance.
The robot's water tank is 80 ml on all three models, standard capacity for robots with a multifunctional base that refill water during mopping.
Real-World User Experience
For large homes, the Dreame L10s Ultra Gen 3 stands out for its greater suction power and slightly superior autonomy. If you have thick carpets or pets that shed a lot of hair, those 25,000 Pa make a difference compared to the 19,000 Pa of the other two. The extendable side brush also helps in homes with many corners.
The Mova E40 Ultra is interesting if you live with long-haired pets, thanks to the anti-tangle side brush. The fact that the detergent tank is optional can be seen as an advantage if you prefer to use your own products or as a disadvantage if you're looking for total convenience. The absence of tray self-cleaning requires somewhat more maintenance.
The Dreame L40 Ultra AE emerges as the most complete option. The AI camera and dirt detection provide a superior level of autonomy, especially in homes with small children where there are scattered toys or in homes with pets where the robot must identify cables, feeding bowls or dirtier areas. Remote camera access adds versatility, allowing you to monitor the home or locate lost objects. The liftable TriCut 3.0 brush improves both vacuuming and mopping.
As for maintenance, the Dreame L10s Ultra Gen 3 requires less intervention thanks to third-generation tray self-cleaning. The Dreame L40 Ultra AE also includes it, although second generation. The Mova E40 Ultra needs manual tray cleaning, a task that should be done weekly to avoid dirt accumulation.
Conclusion: Which One to Choose?
Choose the Mova E40 Ultra if you're looking for a robot with a complete multifunctional base at a tight price and you don't mind doing without an AI camera. The anti-tangle side brush is practical if you have long-haired pets. Accept that you'll have to manually clean the washing tray and that the detergent tank is optional.
Choose the Dreame L10s Ultra Gen 3 if you need the greatest possible suction power and value the extendable side brush for corners. Third-generation tray self-cleaning reduces maintenance and the 231-minute autonomy makes it ideal for large homes. It's a balanced option that doesn't incorporate a camera but offers excellent performance in vacuuming and mopping.
Choose the Dreame L40 Ultra AE if you want the maximum level of automation and intelligence. The AI camera, recognition of 120 obstacles, dirt detection and remote access make it the most advanced of the three. The liftable TriCut 3.0 brush and larger dust bin are additional advantages. Ideal for homes with many obstacles, pets or if you value being able to monitor your home through the robot when you're away.
