Introduction
The Mova E40 Ultra, the Dreame L40 Ultra and the Roborock Qrevo S5V represent three distinct propositions within the robot vacuum cleaner segment with multifunction base. The Dreame model arrived on the market in 2024, whilst the Mova and Roborock options were launched in 2025. All three integrate a mopping system with rotating mops and stations that automate washing and drying, albeit with notable differences in power, navigation and intelligent functions.
These differences make them more or less suitable depending on the type of home and the specific needs of each user. Those seeking maximum suction power will find a remarkable figure in the Mova E40 Ultra, whilst the Dreame L40 Ultra opts for a more comprehensive navigation system with artificial intelligence cameras. The Roborock Qrevo S5V positions itself as a balanced alternative with a specific brush design to prevent hair tangles.
Power and Suction
Suction power marks a significant difference between these models. The Mova E40 Ultra reaches 19,000 Pa, a figure that practically doubles the 11,000 Pa of the Dreame L40 Ultra and clearly exceeds the 12,000 Pa of the Roborock Qrevo S5V. This greater capacity can translate into better results when vacuuming carpets or floors with ingrained dirt.
The main brush design varies considerably. The Roborock Qrevo S5V features a DuoDivide Anti-Tangle system that pushes hairs towards the centre to facilitate their suction, reducing tangles. The Dreame L40 Ultra is equipped with the TriCut 3.0 brush, which combines bristles with blades to cut hairs that become wrapped. The Mova E40 Ultra uses a simple silicone brush, less prone to tangles than traditional bristles but without the specific system of the other two.
Only the Dreame L40 Ultra can lift the main brush during mopping, preventing it from touching the wet floor. This function is also present in the side brush, which is additionally extendable to better reach corners. The Mova E40 Ultra and the Roborock Qrevo S5V do not lift any of their brushes. All three models feature an anti-tangle side brush.
Mopping
All three robots mop with two rotating mops. The Roborock Qrevo S5V rotates at 200 RPM, slightly faster than the 180 RPM of the Mova E40 Ultra and the Dreame L40 Ultra. All lift the mops when they detect carpets: 10.5 mm in the Mova and Dreame models, 10 mm in the Roborock.
The Mova E40 Ultra and the Dreame L40 Ultra integrate the RoboSwing system, which extends the mops laterally through an oscillating movement to better clean edges and get the mop under furniture overhangs. The Roborock Qrevo S5V also extends the mops, although without that specific movement.
Regarding mop washing in the base, the Dreame L40 Ultra uses hot water at 65ºC, which improves the removal of grease and adhered dirt. The Mova E40 Ultra and the Roborock Qrevo S5V wash with cold water. All three dry the mops with hot air at 45°C to prevent bad odours.
Only the Dreame L40 Ultra can automatically remove the mops in the base when you want the robot to vacuum without mopping. It is also the only one that detects dirt both on the mops and on the floor, which allows it to repeat the mop washing or re-mop areas it identifies as dirtier. These functions are not present in the Mova or the Roborock.
Navigation System
All three robots use a 360° LiDAR turret to map the home and avoid obstacles. The Mova E40 Ultra and the Dreame L40 Ultra add a front 3D laser sensor to detect objects at floor level. The Roborock Qrevo S5V does not include this additional sensor.
The most notable difference is in the camera system of the Dreame L40 Ultra, which features a dual camera with artificial intelligence capable of recognising up to 100 different obstacles. This configuration includes LED night vision to map even in total darkness and allows remote access to the camera from the app. It recognises pets and detects curtains to adjust cleaning. Neither the Mova E40 Ultra nor the Roborock Qrevo S5V have a camera.
The Mova E40 Ultra does recognise pets despite not having a camera, probably through the 3D laser sensor. The Roborock Qrevo S5V does not specify this function. Regarding intelligent cleaning, the Dreame L40 Ultra employs CleanGenius 2.0, the Mova E40 Ultra uses CleanGenius 1.0 and the Roborock Qrevo S5V incorporates SmartPlan 1.0. The Dreame's processor is a four-core AI Sage 11.0; the other two do not specify CPU.
Autonomy and Battery
All three feature 5,200 mAh batteries, but autonomy varies. The Mova E40 Ultra offers 210 minutes of operation, the Dreame L40 Ultra reaches 194 minutes and the Roborock Qrevo S5V remains at 180 minutes. These differences may be due to energy management and the suction power used during the cleaning cycle.
In large homes, the extra 30 minutes of the Mova E40 Ultra compared to the Roborock can make the difference between completing cleaning in a single pass or needing to return to the base to recharge. The Dreame L40 Ultra sits at an intermediate point.
Intelligent Functions
The ability to overcome obstacles is similar in all three models, although with small variations. The Dreame L40 Ultra can overcome steps of up to 22 mm, whilst the Mova E40 Ultra and the Roborock Qrevo S5V reach 20 mm. This 2 mm difference may seem minimal, but in practice it facilitates passage over thick carpets or small level changes between rooms.
Only the Dreame L40 Ultra incorporates its own voice assistant integrated into the robot. All three are compatible with external assistants such as Alexa or Google Home.
Multifunction Cleaning Base
All three bases automate the emptying of the dust container and the washing and drying of the mops. The main difference is in washing: the Dreame L40 Ultra washes with hot water at 65ºC, whilst Mova and Roborock use cold water. Additionally, the Dreame base includes second-generation self-cleaning of the washing tray, a function the other two do not have.
The Dreame L40 Ultra incorporates an integrated detergent tank. The Mova E40 Ultra can add it as an optional accessory purchased separately. The Roborock Qrevo S5V does not offer this possibility. The detergent tank dispenses product during mop washing to improve cleaning.
The dust bag capacity is 3.2 litres in the Mova E40 Ultra and the Dreame L40 Ultra, versus 2.7 litres of the Roborock Qrevo S5V. The clean water tanks are 4.5 litres in the first two and 4 litres in the Roborock. Dirty water is stored in 4-litre tanks in Mova and Dreame, 3.5 litres in Roborock.
The Dreame L40 Ultra allows the purchase of an optional plumbing connection kit, although it does not come integrated as standard. Neither the Mova nor the Roborock offer this option.
Dimensions
The robot's height is a determining factor for passing under furniture. The Roborock Qrevo S5V measures 96.5 mm, the Mova E40 Ultra reaches 97 mm and the Dreame L40 Ultra reaches 103.8 mm. Those almost 7 mm difference between the Roborock and the Dreame can prevent the latter from passing under certain sofas or low beds.
The diameter is practically identical: 350 mm in Mova and Dreame, 353 mm in Roborock. The bases of the Mova E40 Ultra and the Dreame L40 Ultra share dimensions: 340 mm wide, 590.5 mm high and 456.7 mm deep. The Roborock Qrevo S5V base is lower (521 mm) but somewhat deeper (487 mm), which can facilitate its placement in spaces with limited height.
Real-World User Experience
For homes with pets that shed a lot of hair, the Roborock Qrevo S5V's DuoDivide brush is specifically designed to reduce tangles. The Dreame L40 Ultra's TriCut 3.0 also manages hair well thanks to its blades. The Mova E40 Ultra's silicone brush prevents tangles, although without such an elaborate system.
In large houses, the 210-minute autonomy of the Mova E40 Ultra and its 19,000 Pa power prove advantageous. The Dreame L40 Ultra compensates with better navigation thanks to its cameras and can clean more autonomously by automatically removing the mops when you only need to vacuum.
If you're seeking the best possible mopping, the Dreame L40 Ultra's hot water mop washing makes a difference compared to the cold water of the other two. Dirt detection allows it to insist on dirtier areas, something neither the Mova nor the Roborock can do.
For spaces with low furniture, the Roborock Qrevo S5V has an advantage with its 96.5 mm height. The Dreame L40 Ultra, at 103.8 mm, may be left out of certain corners. The Dreame's brush-lifting capability is useful if you alternate frequently between vacuuming and mopping, as it prevents the brushes from touching the wet floor.
Conclusion: Which to Choose?
Choose the Mova E40 Ultra if you're seeking maximum suction power (19,000 Pa) and the greatest autonomy (210 minutes). It's ideal for large homes where you need to vacuum carpets or difficult dirt. The relationship between power and autonomy makes it especially suitable for spacious houses with various floor types. It has the RoboSwing system for mopping edges, although it washes the mops with cold water.
Choose the Dreame L40 Ultra if you prioritise intelligent navigation with dual AI camera, recognition of 100 obstacles and remote access to the camera. Mop washing with hot water at 65ºC improves mopping, and dirt detection allows the robot to insist on areas that need it. It can automatically remove the mops to vacuum without mopping and lifts both the main and side brush. It's the most comprehensive option in intelligent functions, although its 103.8 mm height may limit access under some furniture.
Choose the Roborock Qrevo S5V if you have pets and are concerned about hair tangles, thanks to its specific DuoDivide brush. At 96.5 mm height, it's the one that best passes under low furniture. Its mopping speed of 200 RPM is slightly higher and the base is more compact in height (521 mm). It's a balanced option without the advanced functions of the Dreame,
