Introduction
Mova, Dreame's second brand, offers a range of robot vacuum cleaners with multifunctional bases that compete on features at more competitive prices. On this occasion, we analyse three models from the family: the Mova E30 Ultra from 2024, the Mova E40 Ultra launched in 2025, and the Dreame L10s Ultra Gen 3, which arrived on the market in November 2025. All three units feature auto-empty bases, mop washing and drying, although they present important technical differences worth knowing before making a decision.
Whilst the E30 Ultra represents the first generation of this family, the E40 Ultra and the Dreame L10s Ultra Gen 3 incorporate substantial improvements in suction power, battery life and mopping functions. These models are designed for homes looking to maximise automation of daily cleaning without sacrificing good results on hard floors and carpets.
Power and Suction
The most notable difference between these three models lies in suction power. The Mova E30 Ultra remains at 7,000 Pa, a modest figure by current standards that may prove insufficient on thick carpets or for picking up heavier debris. The jump to the E40 Ultra means moving to 19,000 Pa, more than double the capacity, which translates into better performance on all types of surfaces.
The Dreame L10s Ultra Gen 3 takes power up to 25,000 Pa, positioning itself as the most powerful of the three. This figure makes a real difference on medium-pile carpets and when picking up sand or denser debris. For homes with pets that shed a lot of hair, this additional power proves especially useful.
All three units mount the HyperStream brush system, a dual-brush design anchored at one end that significantly reduces hair tangles. None of them offers main brush lifting during mopping, an aspect that poses no problem given that the mops do lift 10.5 mm when carpets are detected.
As for the side brush, only the E40 Ultra incorporates anti-tangle technology, a detail that facilitates maintenance in homes with long hair or pets. The Dreame L10s Ultra Gen 3 stands out with its extendable side brush, which improves cleaning in corners and tight spaces by projecting outwards during sweeping. This function makes a difference in spaces with many angles or furniture against walls.
Mopping
All three models use a twin rotating mop system, but differences appear in advanced functions. The Mova E30 Ultra does not feature mop extension for edges, a limitation that affects the final result on room perimeters. Both the E40 Ultra and the Dreame L10s Ultra Gen 3 do incorporate this extension with Roboswing movement, allowing the mop to project towards skirting boards and clean edges better.
Mop lifting reaches 10.5 mm on all three units, sufficient height to pass over thin carpets without wetting them. The system detects textiles and automatically lifts the mops, avoiding problems in homes with carpets scattered across different rooms.
Mop washing is carried out with hot water in all three cases, improving the removal of adhered dirt compared to cold water systems. A key difference appears here: the E30 Ultra dries mops with cold air, whilst the E40 Ultra and the Dreame L10s Ultra Gen 3 employ hot air. This detail speeds up drying and better prevents bad odours, especially in humid or poorly ventilated environments.
None of the three models automatically removes the mops at the base when only vacuuming is desired, nor do they incorporate dirt detection for automatic re-mopping of dirtier areas. These are functions that some higher-end models offer, but which are not present here.
The E30 Ultra also does not include a water tank on the robot itself, which limits its capacity to moisten mops during mopping between washes at the base. The E40 Ultra and the Dreame L10s Ultra Gen 3 do incorporate 80 ml of water on board, allowing more consistent mopping on large surfaces.
Navigation System
All three robots employ a LiDAR turret with front 3D laser sensor to map the home and avoid obstacles. None incorporates a front camera with artificial intelligence, although they do feature pet recognition through their sensors. This allows the robot to identify the presence of animals and adjust its behaviour, avoiding startling or disturbing them during cleaning.
Navigation is complemented by the CleanGenius system, present on all three models, which optimises routes and adjusts cleaning parameters according to the type of floor detected. They do not have a front LED for night vision or remote camera access, functions reserved for higher ranges with integrated camera.
In practice, the LiDAR navigation system with front 3D sensor proves effective at avoiding common obstacles such as cables, slippers or toys. The absence of a camera does not pose a real problem in day-to-day use, although it does limit remote video surveillance possibilities that some users value.
Battery Life and Battery
All three units mount a 5,200 mAh battery, but battery life data varies significantly. The Mova E30 Ultra provides no information on operating minutes, making it difficult to calculate the surface area it can clean on a single charge. The E40 Ultra reaches 210 minutes of battery life, whilst the Dreame L10s Ultra Gen 3 achieves up to 231 minutes.
That 21-minute difference between the E40 Ultra and the Dreame L10s Ultra Gen 3 can translate into approximately 30-40 additional square metres of coverage, a relevant aspect in large homes or those with complex layouts. For houses over 150 square metres, having greater battery life reduces the likelihood of the robot having to return to the base to recharge before completing cleaning.
Smart Functions
The ability to overcome obstacles is identical on all three models: 20 mm in height. This measurement allows them to negotiate small level changes such as joints between rooms, medium-thickness carpets or thick cables. None of the three robots incorporates a robotic arm or its own voice assistant, although they are compatible with Alexa and Google Home for voice control via external assistants.
Multifunctional Cleaning Base
All three models feature a multifunctional base that performs auto-emptying of the dust bin, mop washing with hot water and drying. The dust bag has a capacity of 3.2 litres in all cases, sufficient for several weeks without needing to change it. The clean water tanks hold 4.5 litres and the dirty water tanks 4 litres, generous dimensions that allow cleaning of large homes without manually refilling or emptying.
The most relevant difference appears in the washing tray self-cleaning. The Dreame L10s Ultra Gen 3 incorporates a third-generation system that automatically cleans the tray where the mops are washed, reducing manual maintenance. The E30 Ultra and E40 Ultra lack this function, requiring periodic cleaning of the tray to prevent accumulation of dirt and bad odours.
Regarding the detergent tank, only the Dreame L10s Ultra Gen 3 includes it as standard. The E40 Ultra offers it as an optional accessory that must be purchased separately, whilst the E30 Ultra does not contemplate it at all. The use of detergent improves mopping results, especially on heavily trafficked floors or those with accumulated grease.
The Dreame L10s Ultra Gen 3 also has an optional kit for connection to water pipes, which allows complete automation of clean water filling and dirty water emptying. This kit is purchased separately and requires installation, but proves interesting for those seeking maximum autonomy without manual intervention.
Dimensions
All three robots share identical dimensions: 350 mm in diameter and 97 mm in height. This height allows them to pass under most furniture, sofas and beds with legs of at least 10 cm. The bases also present practically identical measurements, with 340 mm width and around 590 mm height. Depth varies minimally: 456.7 mm on the E30 Ultra and E40 Ultra versus 457 mm on the Dreame L10s Ultra Gen 3, an imperceptible difference in practice.
By sharing dimensions, all three models require the same installation space and can access the same corners under furniture. There is no functional advantage of one over another in this regard.
Real-World User Experience
For small or medium-sized homes without pets, the Mova E30 Ultra can meet basic cleaning expectations, although its lower power and the absence of mop extension limit results in corners and on carpets. The lack of battery life data creates uncertainty about its performance on large surfaces.
The E40 Ultra represents a significant qualitative leap thanks to its 19,000 Pa suction, anti-tangle side brush and mop extension for edges. Hot air drying and 210 minutes of battery life make it a balanced option for homes up to 150 square metres with pets. The 80 ml water tank on the robot improves mopping consistency on large surfaces.
The Dreame L10s Ultra Gen 3 positions itself as the most complete of the three. Its 25,000 Pa power, extendable side brush and third-generation tray self-cleaning reduce maintenance and improve the final result. The 231 minutes of battery life allow coverage of large homes without interruptions, and the detergent tank as standard optimises mopping. For homes with pets that shed a lot of hair or with complex layouts, this model offers the best overall performance.
In all cases, the multifunctional base with hot water mop washing makes the difference compared to more basic robots. Mopping proves effective on hard floors such as stoneware, tiles or laminate flooring, although on very adhered stains it may require a second pass.
Conclusion: Which to Choose?
Choose the Mova E30 Ultra if you're looking for a robot with a multifunctional base at a competitive price for a small home without thick carpets or pets. Bear in mind that its limited power and the absence of mop extension affect results in corners and on textiles. Cold air drying also requires more time.
Choose the Mova E40 Ultra if you need a balance between features and price in a medium-sized house with pets. Its 19,000 Pa suction, anti-tangle side brush and mop extension substantially improve results. Hot air drying and 210 minutes of battery life make it suitable for homes up to 150 square metres. Consider whether you need the optional detergent tank.
