Introduction
This comparison brings together three robot vacuum cleaners with mopping rollers: the Dreame Aqua 10 Ultra Roller, the Roborock Qrevo Curv 2 Flow and the Mova S70 Roller. All three feature roller systems for mopping, a technology that has gained popularity over traditional mops because they apply constant pressure and cover more surface area uniformly.
The Dreame Aqua 10 Ultra Roller stands out for its suction power of 30,000 Pa and a HyperStream dual anti-tangle brush system. The Roborock Qrevo Curv 2 Flow presents a more balanced approach with its DuoDivide system and a battery life of 242 minutes. The Mova S70 Roller, manufactured by Dreame's second brand, positions itself as a more compact alternative with 28,000 Pa of suction and a particularly compact base design.
These models are designed for households seeking complete mopping automation, with multifunctional bases that wash and dry the rollers automatically.
Power and Suction
The most obvious difference in this section is marked by the Dreame Aqua 10 Ultra Roller with its 30,000 Pa of suction, a figure that places it in the highest range on the market. The Mova S70 Roller stays at 28,000 Pa, still very competitive, whilst the Roborock Qrevo Curv 2 Flow offers 20,000 Pa. In practice, these differences are particularly noticeable on thick carpets and in the ability to pick up embedded dirt.
The main brush system varies significantly between the three. The Dreame opts for a HyperStream dual anti-tangle brush, a design with two brushes anchored at one end that prevents hair from tangling around the central axle. The Roborock incorporates the DuoDivide system, which pushes hair towards the central gap to facilitate suction and reduce tangles. The Mova S70 Roller uses a single silicone brush, effective but less advanced than the other two solutions.
Only the Dreame Aqua 10 Ultra Roller and the Roborock Qrevo Curv 2 Flow can lift the main brush during mopping. This allows the mopping roller to work without interference from the brush, improving results on hard floors. The Mova S70 Roller lacks this function.
As for the side brush, all three models lift it when mopping to prevent it from getting unnecessarily wet. The Dreame and Mova feature an extendable side brush to better sweep corners, a function that the Roborock does not include. All three incorporate anti-tangle systems on the side brush, although the Roborock uses a dual side brush that reinforces perimeter sweeping.
Mopping
All three robots use roller systems for mopping, but with differences in pressure and speed. The Dreame Aqua 10 Ultra Roller applies 12N of pressure on the roller, the Mova S70 Roller exerts 17N of pressure and the Roborock Qrevo Curv 2 Flow specifies a 270 mm roller that spins at 200 RPM. These roller systems scrub the floor continuously, which is more effective than traditional static mops.
All three models extend their rollers to better reach edges and can lift them when passing over carpets. The Dreame lifts 14 mm and also covers the roller, the Roborock raises up to 15 mm with cover included, and the Mova reaches 12 mm without specifying whether it covers it. This lift allows the robot to move over carpets without wetting them.
Dirt detection marks an important difference. The Dreame Aqua 10 Ultra Roller and the Roborock Qrevo Curv 2 Flow detect dirt both on the rollers and on the floor, which allows them to go over dirtier areas again or rewash the roller when they detect it is very stained. The Mova S70 Roller does not include any of these sensors, so it mops uniformly without adapting the intensity to the actual dirt.
Navigation System
The Dreame Aqua 10 Ultra Roller uses a retractable 360° LiDAR that hides when not needed, reducing the effective height of the robot. The Roborock Qrevo Curv 2 Flow mounts a traditional 360° LiDAR turret, which explains its greater height. The Mova S70 Roller employs CovertSense dToF, a navigation system without a visible turret that contributes to its lower profile of 90 mm.
In artificial intelligence, the Dreame incorporates a dual RGB camera and recognises up to 240 different types of obstacles, including pets and curtains. The Roborock has one camera and recognises 200 obstacles, also with pet detection but without the ability to identify curtains. The Mova S70 Roller lacks an AI camera and does not specify the number of obstacles it can recognise.
Remote camera access is available on the Dreame and Roborock, allowing you to monitor the home from the app. The Mova does not offer this possibility as it lacks a camera. The night vision LED appears on the first two models, facilitating object recognition in low-light conditions.
Intelligent cleaning systems also differ. The Dreame uses CleanGenius 3.0 with AI Sage 15.0 Octa-core processor, the Roborock implements SmartPlan 3.0, and the Mova does not specify any AI-based intelligent cleaning system. This translates into the first two adapting routes and cleaning strategies according to the type of dirt detected, whilst the Mova follows more conventional patterns.
Battery Life and Battery
The battery capacity of the Dreame Aqua 10 Ultra Roller reaches 6,400 mAh, clearly superior to the 5,200 mAh of the Roborock Qrevo Curv 2 Flow and the Mova S70 Roller. However, actual battery life tells another story: the Roborock achieves 242 minutes of continuous operation, whilst the Dreame stays at 160 minutes. The Mova does not specify battery life.
This difference between capacity and battery life is explained by energy consumption. The Dreame, with its 30,000 Pa of power and dual brush, consumes more energy than the Roborock despite having more battery. For large homes, the Roborock's 242 minutes can make the difference, allowing the entire surface to be completed without intermediate recharges.
Smart Functions
The ability to overcome obstacles varies dramatically. The Dreame Aqua 10 Ultra Roller can climb single steps of up to 42 mm and double steps of up to 80 mm, an exceptional figure that allows it to move between rooms with different floor levels without problems. The Roborock Qrevo Curv 2 Flow climbs 20 mm and the Mova S70 Roller reaches 22 mm, sufficient for thick carpets but limited when facing pronounced level changes.
The built-in voice assistant is present on the Dreame and Roborock, allowing you to give commands directly to the robot without needing to open the app. The Mova S70 Roller does not include this function, although all three are compatible with Alexa and Google Home for external voice control.
Multifunctional Cleaning Base
All three robots have a multifunctional base that empties dust, washes and dries the rollers automatically. The roller washing temperature is where notable differences arise: the Dreame Aqua 10 Ultra Roller washes at 100°C, the Mova S70 Roller at 80°C and the Roborock Qrevo Curv 2 Flow at 75°C. The Dreame's hotter water helps to better eliminate grease and bacteria adhered to the roller.
As for drying, the Roborock dries with hot air at 55°C and the Mova at 70°C. The Dreame does not specify temperature or type of drying. Hot air drying speeds up the process and prevents bad odours better than cold air.
Self-cleaning of the washing tray is present on the Roborock and Mova, but not on the Dreame. This function automatically washes the tray where the rollers are cleaned, reducing manual maintenance. The Dreame compensates with a dual detergent tank that allows different products to be used according to floor type, something that neither the Roborock nor the Mova offer.
The dust bag capacity is 3.2 litres on the Dreame and Mova, compared to 2.7 litres on the Roborock. The clean water tanks are 4 litres on Dreame and Roborock, whilst the Mova goes up to 5 litres. For dirty water, Dreame and Roborock have 3.5 litres and the Mova 4.5 litres. These larger sizes on the Mova reduce maintenance frequency.
The Dreame offers a plumbing connection kit that is purchased separately, eliminating the need to manually refill and empty tanks. Neither the Roborock nor the Mova have this option.
Dimensions
The robot's height is crucial for accessing under furniture. The Mova S70 Roller measures only 90 mm, the Dreame Aqua 10 Ultra Roller 97.5 mm and the Roborock Qrevo Curv 2 Flow 119 mm. This difference of almost 3 cm between the Mova and the Roborock determines which spaces each one can clean. The Mova will access under low beds and sofas where the Roborock will not fit.
The diameter is similar on all three: 350 mm for Dreame and Mova, 353 mm for Roborock. As for the bases, the Mova stands out for its compactness: 340 mm wide, 503 mm high and only 255 mm deep. The Dreame occupies 420x500x440 mm and the Roborock 450x450x450 mm. The Mova's base occupies almost half the space in depth, ideal for tight corners.
Real-world user experience
For large homes, the Roborock Qrevo Curv 2 Flow offers the best battery life with its 242 minutes, sufficient to complete large surfaces without recharging. Its DuoDivide system handles pet hair well, although the Dreame Aqua 10 Ultra Roller goes a step further with its HyperStream dual brush and greater suction power.
In homes with pets, both the Dreame and Roborock detect animals and adjust their behaviour, as well as having effective anti-tangle systems. The Mova S70 Roller, without pet recognition or dirt detection, requires more frequent manual configuration.
For houses with level changes or very thick carpets, the Dreame's ability to overcome 42 mm is decisive. The other two models stay at 20-22 mm, sufficient for normal transitions but limited on pronounced steps.
The Mova S70 Roller's height of 90 mm makes it the best option for homes with low furniture, accessing spaces inaccessible to the Roborock. Its compact base also facilitates installation in reduced spaces.
Maintenance is more convenient on the Roborock and Mova thanks to the self-cleaning washing tray. The Dreame compensates with its dual detergent tank and the
