Introduction
Choosing between the Roborock Qrevo Curv 2 Flow, the Mova V50 Ultra and the Dreame X50 Ultra Blanca requires detailed analysis of their technical specifications. These three models represent the high-end range of the current market, each with cutting-edge technology and complete multifunction bases that wash and dry the mops automatically. The Roborock arrives in 2026 with a mopping system different from its competitors, whilst Mova and Dreame opt for more traditional but equally powerful configurations.
The Qrevo Curv 2 Flow stands out for its 270 mm roller for mopping and its visible LiDAR turret, whilst Mova V50 Ultra and Dreame X50 Ultra Blanca share the retractable LiDAR system and dual rotating mop. These robots are designed for demanding homes where maximum automation of the cleaning process is sought, from vacuuming to deep mopping without manual intervention.
Power and Suction
Suction power marks a first significant difference. The Mova V50 Ultra leads with 24,000 Pa, whilst both the Roborock Qrevo Curv 2 Flow and the Dreame X50 Ultra Blanca remain at 20,000 Pa. This advantage of the Mova can be especially noticeable on long-pile carpets or in homes with pets that shed a lot of hair.
Regarding the brushing system, the Roborock mounts the DuoDivide Antienredos brush, designed to push hairs towards the centre and facilitate their suction. Mova and Dreame equip dual HyperStream brush, with two modules anchored at one end that minimise tangles. All three systems are designed to reduce manual maintenance, albeit with different technical approaches.
All models lift the main brush during mopping, preventing it from getting unnecessarily wet. They also lift the side brush when mopping. However, only Mova V50 Ultra and Dreame X50 Ultra Blanca feature an extendable side brush to better reach corners. The Roborock does without this function, which may influence cleaning of corners and edges.
Mopping
Here we find one of the most relevant differences in this robot vacuum comparison. The Roborock Qrevo Curv 2 Flow uses a 270 mm roller for mopping, a system that covers more contact surface with the floor continuously. Mova V50 Ultra and Dreame X50 Ultra Blanca opt for two rotating mops, the most widespread design in the high-end range.
All three models extend the mops to better reach edges. Mova and Dreame also incorporate the Roboswing system, which allows the robot to perform a lateral movement to slightly introduce the mop under furniture or protrusions. The Roborock does not include this function.
Mop lifting also varies. The Roborock Qrevo Curv 2 Flow lifts the mops up to 15 mm and can also retract them completely, ideal for passing over carpets without wetting them. Mova V50 Ultra and Dreame X50 Ultra Blanca reach 10.5 mm of lift, sufficient for medium-thickness carpets but without total retraction.
A notable difference is the temperature of the mopping water. The Mova V50 Ultra mops with hot water at 80°C, which helps to better dissolve grease and disinfect the floor. Both the Roborock and the Dreame use cold water. In practice, this can make a difference in kitchens or areas with stuck-on dirt.
Mova and Dreame automatically remove the mops at the base when only vacuuming is needed, avoiding dragging them unnecessarily. The Roborock does not offer this function. All three detect dirt both on the mops and on the floor to adapt cleaning intensity.
Navigation System
The Roborock Qrevo Curv 2 Flow mounts a visible LiDAR turret, whilst Mova V50 Ultra and Dreame X50 Ultra Blanca employ retractable LiDAR. This difference explains part of the variation in height: the Roborock measures 119 mm, which limits its ability to slip under certain furniture. Mova and Dreame, at 89-89.5 mm, access lower spaces without problems.
All three are equipped with an artificial intelligence camera, although Mova and Dreame incorporate dual cameras compared to the Roborock's single one. All recognise up to 200 types of obstacles, identify pets and allow remote access to the camera for surveillance. They also include LED for night vision.
An exclusive function of Mova V50 Ultra and Dreame X50 Ultra Blanca is curtain detection. This prevents the robot from getting tangled or dragging hanging fabrics. The Roborock lacks this capability.
Regarding intelligent cleaning systems, the Roborock uses SmartPlan whilst Mova and Dreame employ CleanGenius. All recognise stains using AI and adjust cleaning accordingly. The Dreame specifies that it uses the AI Sage 13.0 algorithm, although the other two do not detail the specific processor.
Autonomy and Battery
The Mova V50 Ultra and the Dreame X50 Ultra Blanca mount 6,400 mAh batteries, whilst the Roborock Qrevo Curv 2 Flow remains at 5,200 mAh. However, real autonomy tells another story: the Roborock reaches 242 minutes, exceeding the Mova's 220 and the Dreame's 180.
This difference suggests that the Roborock optimises energy consumption better despite having lower battery capacity. For large homes, those 242 minutes of the Qrevo Curv 2 Flow can be decisive, allowing completion of cleaning of large surfaces without intermediate recharges.
Smart Functions
All three models overcome obstacles, albeit with different capabilities. The Roborock Qrevo Curv 2 Flow crosses steps up to 20 mm, whilst Mova V50 Ultra and Dreame X50 Ultra Blanca are limited to simple steps without specifying exact height. This may matter in homes with level differences between rooms or with shower trays.
All incorporate their own voice assistant and compatibility with Alexa and Google Home. None mounts a robotic arm, a function that has not yet become widespread in this market segment.
Multifunction Cleaning Base
All three bases automatically empty the robot's dust container, wash the mops and dry them. The Roborock washes with hot water at 75°C and dries with hot air at 45°C. The Mova also washes with hot water at 75°C and dries with hot air at 45°C. The Dreame likewise washes with hot water at 75°C and dries with hot air at 45°C.
Mova and Dreame feature third-generation tray self-cleaning, whilst the Roborock simply specifies that it includes self-cleaning without detailing generation. All three systems keep the tray in hygienic conditions without manual intervention.
UV disinfection is only present in Mova V50 Ultra and Dreame X50 Ultra Blanca. The Roborock does not incorporate this technology. Regarding detergent, the Mova stands out with a dual tank, allowing use of different products depending on floor type. The Dreame has a single tank and the Roborock completely lacks this function.
Storage capacities vary slightly. The Roborock has a 2.7-litre dust bag, whilst Mova and Dreame offer 3.2 litres. For clean water, the Roborock and the Mova match with 4 litres, but the Dreame rises to 4.5 litres. For dirty water, Roborock and Mova share 3.5 litres compared to the Dreame's 4 litres.
Only the Dreame X50 Ultra Blanca offers an optional plumbing connection kit, which must be purchased separately. None includes integrated connection from the factory.
Dimensions
The robot's height is probably the most important dimensional difference. The Roborock Qrevo Curv 2 Flow reaches 119 mm due to its visible LiDAR turret. Mova V50 Ultra measures 89.5 mm and Dreame X50 Ultra Blanca barely 89 mm thanks to retractable LiDAR. This means that Mova and Dreame slip under furniture, beds or sofas where the Roborock cannot access.
In diameter, the Roborock has 353 mm whilst Mova and Dreame share 350 mm. Minimal differences that do not significantly affect manoeuvrability.
The bases also present variations. The Roborock forms an almost perfect cube of 450 mm in all three dimensions. The Mova measures 420 mm wide, 470 mm high and 458 mm deep. The Dreame is narrower (340 mm) but considerably taller (590.5 mm), with 456.7 mm depth. It is advisable to measure the available space before deciding, especially with the Dreame which exceeds 59 cm in height.
Real-world experience
For large homes, the Roborock Qrevo Curv 2 Flow offers the greatest autonomy with 242 minutes, sufficient to cover large surfaces without interruptions. Its 5,200 mAh battery is better optimised than that of its competitors despite having lower nominal capacity.
If you live with pets, all three models incorporate anti-tangle brushes and specific animal recognition. The Mova V50 Ultra provides an advantage with its 24,000 Pa of suction, especially useful for hair embedded in carpets. The Mova's dual detergent tank also allows keeping specific products separate for eliminating pet odours.
In homes with low furniture, Mova V50 Ultra and Dreame X50 Ultra Blanca access spaces where the Roborock cannot reach due to its 119 mm height. This may mean leaving important areas under beds or sofas uncleaned.
For those seeking maximum hygiene, the Mova combines hot water at 80°C for mopping the floor, mop washing at 75°C, UV disinfection and dual detergent tank. The Dreame offers UV and hot water in mop washing, but mops with cold water. The Roborock does without UV and detergent, although it maintains hot water in mop washing.
Automatic mop removal in Mova and Dreame facilitates alternating between pure vacuuming and mopping without handling the robot. The Roborock requires manual intervention for this task.
