Introduction
Mova presents two distinct proposals in terms of cleaning technology: the E40 Ultra from 2025 and the S70 Roller launched in 2026. Both units feature a complete multifunction base that includes auto-emptying, mop washing and drying, but they differ notably in their mopping approach and in several technical aspects worth analysing before deciding.
The E40 Ultra opts for the traditional system of two rotating mops with extendable movement, whilst the S70 Roller introduces a 270 mm roller that radically changes the way it mops. This difference in the mopping system largely defines the features and the type of user each model is aimed at.
Power and Suction
The power difference between these Mova robot vacuum cleaners is considerable. The E40 Ultra offers 19,000 Pa, a figure that proves sufficient for most domestic situations. The S70 Roller reaches 28,000 Pa, which represents a significant leap especially useful if there are carpets at home or pets that shed a lot of hair.
Both models feature a simple-type main brush, without advanced anti-tangle features. This means that in homes with long hair or pets, attention will need to be paid to maintaining the central brush.
Where important differences do appear is in the side brush. The E40 Ultra has a fixed side brush, whilst the S70 Roller incorporates an extendable and liftable one. This allows the S70 Roller to sweep corners better when it extends the brush, and avoid interference during mopping by lifting it. Both units include anti-tangle technology on the side brush.
Mopping
Here we find the biggest difference in this robot vacuum cleaner comparison. The Mova E40 Ultra uses two rotating mops with extension capability through movement, which allows it to get closer to edges and improve coverage on the sides. The mop system lifts 10.5 mm when it detects carpets.
The Mova S70 Roller completely changes the approach with a 270 mm roller. This type of system tends to offer more uniform and continuous mopping, as the roller maintains constant contact with the floor. It also features edge extension and lifts the roller up to 12 mm, slightly more than its competitor.
The E40 Ultra base washes the mops with cold water, whilst the S70 Roller does so with hot water. This detail can make a difference in washing effectiveness, especially when the mops accumulate greasy or stuck-on dirt. Both dry with hot air, which helps prevent bad odours.
The S70 Roller adds self-cleaning of the washing tray, something the E40 Ultra doesn't include. This reduces manual maintenance of the base. Neither automatically removes the mops at the base to perform vacuuming-only tasks, nor detects dirt on mops or floor to adjust cleaning.
The E40 Ultra allows adding an optional detergent tank that is purchased separately. The S70 Roller doesn't offer this possibility.
Navigation System
The Mova E40 Ultra robot vacuum cleaner features a LiDAR 3D turret, the most common system in mid-to-high-end robots. The S70 Roller uses CovertSense dToF, a technology that dispenses with the traditional turret and is usually integrated more discreetly into the robot's design.
Both units include a front 3D laser sensor to avoid obstacles and have object recognition capability. The E40 Ultra incorporates specific pet recognition, a function the S70 Roller doesn't have. This can prove useful if there are animals at home and you want the robot to adapt its behaviour.
The E40 Ultra includes intelligent cleaning via CleanGenius AI, whilst the S70 Roller doesn't have this function. Neither has a camera with remote access nor LED for night vision.
Autonomy and Battery
Both models share the same battery capacity: 5,200 mAh. The E40 Ultra specifies an autonomy of 210 minutes, data that isn't available for the S70 Roller. In practice, with that battery capacity both should offer sufficient autonomy for medium-to-large-sized homes on a single charge.
The S70 Roller's greater suction power could translate into slightly higher consumption when working at maximum, although this will depend on actual use and the cleaning modes selected.
Smart Functions
The Mova E40 Ultra can overcome obstacles up to 20 mm in height, whilst the S70 Roller reaches 22 mm. This small difference can be particularly noticeable in homes with thick carpets or small level changes between rooms.
Both robots are compatible with external voice assistants such as Alexa or Google Home, which facilitates their integration into home automation ecosystems.
Multifunction Cleaning Base
Both bases perform auto-emptying of the dust container, washing and drying of mops with hot air. The dust bag capacity is identical: 3.2 litres, sufficient for several weeks without needing to change it.
The water tanks present slight differences. The E40 Ultra has 4.5 litres of clean water and 4 litres of dirty water. The S70 Roller slightly reverses the proportions: 5 litres of clean water and 4.5 litres of dirty water. In both cases, the capacity allows multiple mopping sessions without refilling.
As already mentioned, the S70 Roller includes self-cleaning of the washing tray, whilst the E40 Ultra requires manual cleaning. Neither offers UV disinfection nor the possibility of connection to water pipes.
Dimensions
The diameter of both robots is 350 mm, but the height varies. The E40 Ultra measures 97 mm tall, whilst the S70 Roller stays at 90 mm. Those 7 mm of difference can be decisive for passing under certain furniture or low sofas.
The base dimensions mark a notable difference. The E40 Ultra has a base of 340 mm wide, 590.5 mm tall and 456.7 mm deep. The S70 Roller maintains the same width but considerably reduces the height to 503 mm and especially the depth to only 255 mm. This makes the S70 Roller base take up considerably less space, something to consider if the space designated for the base is limited.
Real-World User Experience
The Mova E40 Ultra proves suitable for medium-sized homes where a balance between features and price is sought. Its extendable rotating mop system offers good mopping results, although cold water washing of the mops may be less effective with stuck-on dirt. The 210-minute autonomy allows covering large surfaces without interruptions.
The S70 Roller is designed for those who prioritise suction power and more intensive mopping thanks to the roller. Its greater capacity to overcome obstacles and the extendable side brush improve coverage in corners and edges. The more compact base facilitates its placement in reduced spaces, and hot water mop washing together with tray self-cleaning reduce maintenance.
For homes with pets, the E40 Ultra offers specific recognition that can prove useful. However, the S70 Roller's greater power partly compensates for this absence when it comes to picking up accumulated hair. Both require attention to the main brush, as neither incorporates advanced anti-tangle technology.
The S70 Roller's lower profile allows it to access under furniture where the E40 Ultra might have difficulties. This is worth bearing in mind if there are many low spaces to clean.
Conclusion: Which to Choose?
Choose the Mova E40 Ultra if: you're looking for a complete robot with pet recognition and you don't mind doing a bit more manual maintenance on the base. Its extendable rotating mop system works well in most situations, and the possibility of adding an optional detergent tank may interest you. The specified autonomy of 210 minutes makes it suitable for large homes.
Choose the Mova S70 Roller if: you prioritise suction power and want more effective mopping thanks to the roller and hot water washing. Its more compact base proves ideal when space is limited, and tray self-cleaning reduces maintenance. The extendable and liftable side brush improves edge cleaning, and its lower height allows it to access under low furniture more easily. It's the best option for those seeking advanced features and less manual intervention.
