Introduction
Choosing a high-end robot vacuum can be complicated when the technical differences are subtle yet decisive. The Dreame L40s Pro Ultra and the Mova V50 Ultra, both launched in 2025, represent the latest generation of robots with multifunctional base stations, whilst the Dreame X40 Ultra from 2024 remains a solid benchmark in the market. All three models share the same philosophy: powerful suction, mopping with rotating mops and base stations that manage all maintenance.
These devices are designed for homes seeking total automation of the cleaning process. The multifunctional base station washes and dries the mops automatically, which makes the difference compared to more basic solutions. However, the differences between them lie in details such as suction power, the navigation system or improvements to the cleaning base station.
Power and Suction
Suction power is one of the aspects where the differences become most evident. The Mova V50 Ultra leads with 24,000 Pa, a figure that far exceeds the 19,000 Pa of the Dreame L40s Pro Ultra and practically doubles the 12,000 Pa of the Dreame X40 Ultra. This difference translates into greater capacity to extract ingrained dirt from carpets or vacuum heavier particles.
All three models incorporate dual HyperStream brushes, a system that significantly reduces hair tangles thanks to its design of two brushes anchored at one end. This is especially useful in homes with pets. Additionally, all feature an extendable and liftable side brush, allowing better sweeping of corners and avoiding dragging debris when mopping.
Battery capacity also varies: the Mova V50 Ultra and the Dreame X40 Ultra integrate 6,400 mAh, whilst the L40s Pro Ultra settles at 5,200 mAh. Despite this difference, both the L40s Pro Ultra and the Mova V50 Ultra offer 220 minutes of autonomy, compared to the 194 minutes of the X40 Ultra. This suggests more efficient energy management in the Mova model.
Mopping
The mopping system is similar across all three robots: two rotating mops with lateral extension using Roboswing movement, which allows better reach of edges and insertion of mops under furniture overhangs. All three options lift the mops 10.5 mm when they detect carpets, sufficient to avoid wetting them in most cases.
The major difference lies in the mopping water temperature. The Mova V50 Ultra mops with hot water at 70°C, which facilitates the dissolution of grease and adhered dirt. The Dreame L40s Pro Ultra and the X40 Ultra use cold water, which may be less effective on difficult stains.
All three models detect dirt both on the mops and on the floor, adjusting the washing or scrubbing process as necessary. They also allow automatic removal of the mops at the base station when only vacuuming is desired, avoiding dragging them unnecessarily.
Navigation System
The Dreame L40s Pro Ultra and the X40 Ultra use a traditional LiDAR turret, which increases their overall height. The Mova V50 Ultra, however, integrates retractable LiDAR that reduces the robot's height to 89.5 mm, allowing it to access under lower furniture. This difference of more than 14 mm compared to the L40s Pro Ultra can be decisive in homes with low-height sofas or beds.
All three devices incorporate dual cameras with artificial intelligence and a front 3D laser sensor to avoid obstacles. The Mova V50 Ultra stands out by recognising up to 200 different types of obstacles, surpassing the 180 of the L40s Pro Ultra and the 120 of the X40 Ultra. This broader recognition capability improves navigation in complex environments.
All include LED for night vision and remote camera access, allowing home monitoring from the app. They also recognise pets and detect curtains to avoid tangles. The CleanGenius system is present in all three models, optimising routes and adjusting cleaning parameters according to detected dirt.
Autonomy and Battery
With 220 minutes of autonomy, the Dreame L40s Pro Ultra and the Mova V50 Ultra offer longer duration than the 194 minutes of the X40 Ultra. This is especially relevant in large homes where the robot needs to cover more surface area without interruptions.
The battery capacity of the Mova V50 Ultra (6,400 mAh) is superior to that of the L40s Pro Ultra (5,200 mAh), but both achieve the same autonomy. This indicates more efficient energy management in the Dreame model, which manages to extract more performance from a smaller battery.
Smart Functions
Regarding obstacle-climbing capability, the Dreame X40 Ultra specifies that it can overcome steps up to 22 mm. The other two models indicate capability for simple steps, without detailing the exact height. In practice, this can make a difference when facing thick carpets or small level changes between rooms.
The Dreame L40s Pro Ultra and the Mova V50 Ultra incorporate their own voice assistant, a function absent in the X40 Ultra. All three models are compatible with external assistants such as Alexa or Google Home, but having an integrated assistant allows greater direct control from the robot itself.
Multifunctional Cleaning Base Station
The base stations of all three models manage auto-emptying of the dust bin, washing and drying of mops. All use hot water at 70°C to wash the mops and hot air to dry them, guaranteeing hygiene and preventing bad odours. The dust bag capacity is identical: 3.2 litres in all three cases.
The Mova V50 Ultra differentiates itself by including UV disinfection in the base station, something the Dreame models do not offer. This function adds an extra level of hygiene by eliminating bacteria during the mop cleaning process.
Another significant difference lies in the detergent tank. The Mova V50 Ultra integrates a dual tank, allowing the use of two types of product depending on the floor type or need. The L40s Pro Ultra and the X40 Ultra feature a single tank.
The self-cleaning of the washing tray is third generation in the L40s Pro Ultra and the Mova V50 Ultra, whilst the X40 Ultra uses second generation. This implies a more advanced and efficient process in the more recent models.
The Dreame L40s Pro Ultra and the X40 Ultra offer an optional plumbing connection kit, which must be purchased separately. The Mova V50 Ultra does not have this option. Water tank capacities vary slightly: the L40s Pro Ultra and the X40 Ultra have 4.5 litres of clean water and 4 litres of dirty water, whilst the Mova V50 Ultra reduces to 4 litres of clean water and 3.5 litres of dirty water.
Dimensions
The diameter is identical across all three robots: 350 mm. Height is where important differences appear. The Mova V50 Ultra measures 89.5 mm thanks to its retractable LiDAR, the Dreame X40 Ultra reaches 97 mm and the L40s Pro Ultra reaches 103.8 mm. This difference of 14.3 mm between the Mova and the L40s Pro Ultra can determine whether or not the robot accesses under certain furniture.
The base station dimensions also vary. The Mova V50 Ultra is wider (420 mm compared to 340 mm) but lower (470 mm compared to 590.5 mm). This means it occupies more horizontal space but less vertical space, an aspect to consider depending on the intended location for the base station.
Real-World User Experience
For large homes, the Mova V50 Ultra offers the best combination of power (24,000 Pa) and autonomy (220 minutes), in addition to the most extensive battery capacity. Its hot water mopping is more effective on floors with grease or adhered dirt.
In homes with pets, all three models incorporate the HyperStream brush that reduces tangles, but the greater power of the Mova V50 Ultra facilitates the extraction of hair embedded in carpets. The dual detergent tank also allows the use of specific products to eliminate odours.
If the home has low furniture, the Mova V50 Ultra with its 89.5 mm height accesses spaces where the other two models cannot enter. This difference can be decisive for cleaning under low-height beds or sofas.
The UV disinfection of the Mova V50 Ultra provides an extra level of hygiene that may be valued in homes with young children or allergy sufferers. The third-generation self-cleaning system in this model and in the L40s Pro Ultra reduces manual maintenance of the base station.
