Introduction
This robot vacuum comparison analyses three 2025 models that represent the most advanced range on the market: the Dreame L40s Pro Ultra, the Roborock Qrevo CurvX and the Mova V50 Ultra. All three incorporate complete multifunctional bases with mop washing and drying, navigation systems with artificial intelligence and active mopping capabilities. These are devices designed for users seeking maximum autonomy in home cleaning, with technologies that go beyond simple vacuuming.
The Dreame L40s Pro Ultra opts for a traditional LiDAR turret and a more compact base design. The Roborock Qrevo CurvX features a retractable LiDAR that notably reduces the robot's height. The Mova V50 Ultra stands out for integrating hot water in floor mopping and UV disinfection, features that make significant differences in the final cleaning result.

Power and Suction
Suction power shows important differences between the three models. The Mova V50 Ultra leads with 24,000 Pa, followed by the Roborock Qrevo CurvX with 22,000 Pa and the Dreame L40s Pro Ultra with 19,000 Pa. In practice, these figures particularly influence performance on long-pile carpets or in homes with pets where embedded dirt requires greater extraction capacity.
Regarding the brushing system, we find relevant technical differences. The Dreame L40s Pro Ultra and the Mova V50 Ultra feature the HyperStream dual brush system, specifically designed to prevent hair tangles. The Roborock Qrevo CurvX incorporates the DuoDivide anti-tangle brush, which pushes hairs towards the central gap to facilitate suction. All three systems are designed to minimise maintenance, albeit with different approaches.
A functional difference appears in the side brush: the Dreame and the Mova can lift it during mopping, whilst the Roborock keeps the side brush fixed. This can be particularly noticeable when mopping areas where you don't want the side brush to disperse water or touch wet surfaces. All three models include an extendable and anti-tangle side brush.
Mopping
All three robots use two rotating mops for active mopping, but the differences in their implementation are notable. The Mova V50 Ultra mops the floor with hot water at 65°C, a feature that improves the dissolution of grease and stuck-on stains. The Dreame and the Roborock use cold water to mop the floor, although both wash the mops in the base with hot water at 70°C.
Mop extension works on all three devices, although the Dreame L40s Pro Ultra and the Mova V50 Ultra add the Roboswing system, which allows the robot to perform a lateral movement to introduce the mop slightly under furniture or protrusions. The Roborock extends the mops without this additional movement.
Regarding mop lifting, the Roborock Qrevo CurvX offers a range of 7 to 17 mm, adaptable according to the surface. The Dreame and the Mova lift the mops up to 10.5 mm. This function is useful when the robot moves from hard floors to carpets, avoiding wetting the fibres.
Automatic mop removal at the base to perform vacuuming-only tasks is available on the Dreame L40s Pro Ultra and the Mova V50 Ultra, but not on the Roborock. All three models detect dirt both on the mops and on the floor, adjusting cleaning intensity as necessary.
Navigation System
The navigation system presents differences in LiDAR design. The Dreame L40s Pro Ultra features a traditional LiDAR turret that protrudes at the top, whilst the Roborock Qrevo CurvX and the Mova V50 Ultra use retractable LiDAR, which reduces the robot's total height and facilitates access under low furniture.
All three devices incorporate dual cameras with artificial intelligence and a front 3D laser sensor for obstacle avoidance. The Mova V50 Ultra recognises up to 200 different objects, the Dreame identifies 180 and the Roborock 108. These figures reflect each system's ability to distinguish household items and adapt the cleaning route.
Curtain recognition works on the Dreame L40s Pro Ultra and the Mova V50 Ultra, allowing the robot to detect hanging fabrics and adjust its behaviour. The Roborock Qrevo CurvX does not include this specific function. All three models recognise pets, have remote camera access and feature LEDs for night vision.
Autonomy and Battery
Battery capacity shows substantial differences. The Roborock Qrevo CurvX and the Mova V50 Ultra integrate 6,400 mAh batteries, whilst the Dreame L40s Pro Ultra features a 5,200 mAh one. Despite this difference in capacity, all three models offer a declared autonomy of 220 minutes.
This autonomy is sufficient for medium-large sized homes in a single cleaning session. In practice, intelligent battery management allows the robots to return to the base if they need to recharge during a complete clean, then resuming from where they left off.
Smart Functions
The ability to overcome simple steps is present on all three models, allowing them to cross small level differences between rooms or the transition to thick carpets. All three devices incorporate their own voice assistant in addition to compatibility with Alexa and Google Home.
The Mova V50 Ultra and the Dreame L40s Pro Ultra include AI stain recognition, a function that identifies particularly dirty areas and increases cleaning intensity in those zones. The Roborock Qrevo CurvX does not have this specific feature, although its SmartPlan system manages cleaning intelligently.
Multifunctional Cleaning Base
All three bases perform auto-emptying of the dust container, mop washing and drying. Washing is carried out with hot water at 70°C in all three cases, guaranteeing deep cleaning of the mops. Drying also uses hot air on all models, preventing bad odours and bacterial proliferation.
Self-cleaning of the washing tray reaches the third generation on all three devices, minimising manual maintenance. UV disinfection is only present on the Mova V50 Ultra, adding an additional layer of hygiene at the base.
The detergent tank marks important differences: the Mova V50 Ultra incorporates a double tank for different types of flooring or products, the Dreame L40s Pro Ultra includes a single tank and the Roborock Qrevo CurvX lacks this function. Automatic detergent dosing during mop washing improves results without user intervention.
Regarding capacities, the dust bag reaches 3.2 litres on the Dreame and the Mova, compared to 2.5 litres on the Roborock. The clean water tank is 4.5 litres on the Dreame, 4 litres on Roborock and Mova. Dirty water is stored in tanks of 4 litres (Dreame), 3 litres (Roborock) and 3.5 litres (Mova). The Dreame offers an optional kit for connection to plumbing, although it is purchased separately.
Dimensions
The robot's height is crucial for accessing under furniture. The Roborock Qrevo CurvX measures just 79.8 mm, the Mova V50 Ultra reaches 89.5 mm and the Dreame L40s Pro Ultra reaches 103.8 mm. This difference of more than 24 mm between the Roborock and the Dreame can be decisive in homes with low furniture, sofas or beds with little clearance.
The diameter is similar on all three: 350 mm on Dreame and Mova, 353 mm on Roborock. These measurements are standard and allow manoeuvring in tight spaces without problems.
The bases present size differences. The Dreame's measures 340 mm wide, 590.5 mm high and 456.7 mm deep. The Roborock has a more compact base of 450 x 450 x 450 mm, practically cubic. The Mova sits at an intermediate point with 420 mm wide, 470 mm high and 458 mm deep. This should be considered if the available space for the base is limited.
Real-World Usage Experience
For large homes, the greater battery capacity of the Roborock and the Mova offers an additional margin, although the 220 minutes of autonomy on all three models is sufficient in most cases. The 3.2-litre dust bag capacity on Dreame and Mova reduces the frequency of changes compared to the Roborock's 2.5 litres.
In homes with pets, the suction power of the Mova V50 Ultra (24,000 Pa) and its HyperStream anti-tangle systems provide an advantage. The Roborock, with its DuoDivide brush and 22,000 Pa, also offers solid performance. The Dreame, with 19,000 Pa, remains competent although it falls short in brute force.
The height of the Roborock Qrevo CurvX makes it the best option for homes with low furniture where the other models cannot access. The Mova V50 Ultra stands out when seeking the maximum level of hygiene, thanks to hot water for floor mopping and UV disinfection at the base.
The automatic detergent tank on the Mova and the Dreame simplifies maintenance compared to the Roborock, where you would need to add product manually if desired. Automatic mop removal on Dreame and Mova allows programming vacuuming-only sessions without manual intervention.
Conclusion: Which One to Choose?
Choose the Dreame L40s Pro Ultra if you're looking for a balanced relationship between features and price, you value having a detergent tank and the largest clean water capacity (4.5 litres), and you don't mind sacrificing some suction power.
