Introduction
The Mova E40 Ultra, the Dreame L40 Ultra and the Dreame L40 Ultra AE form a trio of robot vacuum cleaners with multifunctional base that share more similarities than might appear at first glance. The Dreame model arrived in 2024, whilst the Mova versions and the AE variant were introduced in 2025. All three units are designed for users seeking complete automation of mopping and vacuuming, with bases that wash and dry the mops automatically.
The relationship between these machines goes beyond the casual: Mova is Dreame's second brand, which explains the common architecture in many technical aspects. However, there are important differences in power, brushing systems and intelligent functions that are worth analysing before deciding.
Power and Suction
The most striking difference appears in suction power. The Mova E40 Ultra and the Dreame L40 Ultra AE offer 19,000 Pa, a figure that practically doubles the 11,000 Pa of the Dreame L40 Ultra. In practice, this difference is particularly noticeable on medium or long pile carpets and in tile joints where fine dust accumulates.
The brushing system marks another relevant distinction. The Mova E40 Ultra mounts a SimpleCut main brush, whilst both Dreame models are equipped with the TriCut 3.0 system, which combines bristles with blades designed to cut tangled hair. All three incorporate an anti-tangle side brush, although the Dreame L40 Ultra AE curiously does not include it according to specifications.
Where the Dreame L40 Ultra clearly stands out is in the ability to lift both the main brush and the side brush during mopping. This allows mopping without the brushes touching the wet floor, preventing them from getting dirty and spreading dirt. Additionally, its extendable side brush improves sweeping in corners. Neither the Mova E40 Ultra nor the Dreame L40 Ultra AE offer these lifting features.
Battery life also varies: the Mova E40 Ultra reaches 210 minutes, compared to the 194 of the Dreame L40 Ultra. This data is not specified for the AE model, although it shares the same 5,200 mAh battery as the other two.
Mopping
All three robots use two rotating mops with side extension and Roboswing movement, which allows the mops to slightly reach under furniture and ledges. Mop lifting is identical on all: 10.5 mm, sufficient to pass over thin carpets without wetting them.
The bases of all three models wash the mops with hot water and dry them with hot air, an important detail to prevent bad odours and bacterial growth. However, the Dreame L40 Ultra incorporates second-generation self-cleaning on the washing tray, a function that the Mova E40 Ultra does not have. The Dreame L40 Ultra AE does include this self-cleaning.
An exclusive function of the Dreame L40 Ultra is the automatic detachment of the mops at the base. This means that the robot can remove the mops when you only need to vacuum, without having to do it manually. It is especially convenient if you alternate simple vacuuming days with complete mopping sessions.
Both the Dreame L40 Ultra and the AE detect dirt on the mops and on the floor, adjusting re-mopping or re-washing as necessary. The Mova E40 Ultra does not incorporate these intelligent detections.
As for the detergent tank, the Mova E40 Ultra offers it as optional (it must be purchased separately), whilst on both Dreame models it comes integrated as standard. All three have a plumbing connection kit available, although it is also purchased separately and should not be considered an important differentiating feature.
Navigation System
Substantial differences appear here. The Dreame L40 Ultra mounts dual AI camera with capacity to recognise up to 100 different objects, including specific curtain detection. It incorporates night vision LED and allows remote access to the camera from the app, a useful function for occasional home surveillance.
The Dreame L40 Ultra AE has a single AI camera but recognises up to 120 objects, surpassing the standard model in this aspect. It also includes LED and remote camera access. The Mova E40 Ultra, on the other hand, lacks an AI camera, front LED and remote access. This does not mean it navigates poorly—all three use LiDAR turret and front 3D laser sensor—but it limits its intelligent object recognition capabilities.
All three models recognise pets, although the absence of a camera on the Mova E40 Ultra reduces the precision of this detection compared to units that integrate artificial vision. The Dreame L40 Ultra uses the AI Sage 11.0 processor, data that is not specified for the other two models.
All incorporate intelligent cleaning based on CleanGenius algorithms, but only the Dreame L40 Ultra adds specific stain recognition through AI, allowing focused re-mopping in specific areas.
Autonomy and Battery
Battery capacity is identical on all three: 5,200 mAh. The Mova E40 Ultra offers 210 minutes of autonomy, sufficient for homes of up to 250-280 m² on a single charge. The Dreame L40 Ultra remains at 194 minutes, a difference of barely 16 minutes that in practice is of little relevance for most homes.
No specific autonomy data is provided for the Dreame L40 Ultra AE, although as it shares the battery with the other two, similar figures can be expected. None of the three specify full charging time.
Intelligent Functions
The ability to overcome obstacles varies slightly: the Dreame L40 Ultra reaches 22 mm, whilst the Mova E40 Ultra and the Dreame L40 Ultra AE remain at 20 mm. Two millimetres can make the difference with certain types of thick carpets or door thresholds.
The Dreame L40 Ultra incorporates its own voice assistant, in addition to compatibility with Alexa and Google Home. The other two models only work with external assistants.
Multifunctional Cleaning Base
All three bases share identical dimensions (340 x 590.5 x 456.7 mm) and similar capacities: 3.2 litre dust bag, 4.5 litre clean water tank and 4 litre dirty water tank. These capacities allow several weeks without manual intervention in medium-sized homes.
The main difference is in the self-cleaning of the washing tray. The Dreame L40 Ultra and the AE incorporate second-generation self-cleaning, which reduces manual maintenance. The Mova E40 Ultra requires periodic manual cleaning of this tray.
As already mentioned, the detergent tank is optional on the Mova E40 Ultra and integrated on the Dreame models. The plumbing connection kit is available for all three, but always as an additional purchase.
Dimensions
The diameter is identical on all three robots: 350 mm. The height presents a small variation: the Mova E40 Ultra and the Dreame L40 Ultra AE measure 97 mm, compared to the 103.8 mm of the Dreame L40 Ultra. Those almost 7 mm of difference can be decisive for slipping under certain low furniture or beds with little clearance from the floor.
The Dreame L40 Ultra AE has a dust bin in the robot itself of 395 ml, larger than the 300 ml of the other two. This can slightly reduce the frequency of emptying at the base if you carry out very intensive cleaning or have pets that shed a lot of hair.
Real-World Usage Experience
For large homes, the Mova E40 Ultra offers greater autonomy and high suction power, although it forgoes advanced functions such as the AI camera or automatic mop detachment. It is a straightforward option for those who prioritise vacuuming and mopping performance without technological complications.
The Dreame L40 Ultra stands out in homes where absolute convenience is valued: automatic mop detachment, dual camera with remote access, tray self-cleaning and liftable brushes that optimise each task. The more moderate suction power is still sufficient for most surfaces, especially hard floors and short pile carpets.
The Dreame L40 Ultra AE sits at a middle point: it recovers the 19,000 Pa power of the Mova, adds AI camera and greater dust bin capacity, but forgoes the liftable and extendable side brush, automatic mop detachment and its own voice assistant. For homes with pets, the TriCut 3.0 systems of the Dreame models can facilitate maintenance compared to the SimpleCut of the Mova.
Conclusion: Which One to Choose?
Choose the Mova E40 Ultra if you seek maximum suction power and autonomy without the need for an AI camera or advanced recognition functions. It is ideal for large homes with hard floors and carpets where raw vacuuming performance is paramount. Its lower height can be advantageous under low furniture.
Choose the Dreame L40 Ultra if you value complete automation and intelligent functions: automatic mop detachment, dual camera with remote access, liftable brushes, curtain detection and its own voice assistant. Perfect for users seeking absolute convenience and are willing to accept more moderate suction power in exchange for greater versatility.
Choose the Dreame L40 Ultra AE if you want a balance between high power (19,000 Pa) and intelligent functions such as AI camera, extended object recognition and larger dust bin in the robot. It is a good option for homes with pets thanks to the TriCut 3.0 brush and its recognition capability, although it forgoes some conveniences of the standard model such as automatic mop detachment or the extendable side brush.
