Introduction
The Mova V50 Ultra and the Roborock Qrevo Slim represent two distinct propositions within the robot vacuum segment with multifunctional base stations. The former arrives in 2025 as a high-end model with powerful specifications, whilst the Qrevo Slim was introduced in 2024, standing out for its compact design. Both units include a mopping system with rotating mops and a base that washes and dries the mops automatically, ensuring minimal maintenance.
The Mova model is designed for homes requiring maximum suction power and extended autonomy, particularly useful in large homes or those with pets. The Roborock unit, with its reduced height, is aimed at users who need a robot capable of sliding under low furniture without sacrificing advanced mopping functions.
Power and Suction
The difference in suction power is notable. The Mova V50 Ultra reaches 24,000 Pa, more than double the 11,000 Pa of the Roborock Qrevo Slim. In practice, this difference translates into better performance on thick carpets and greater capacity to pick up ingrained dirt or heavy debris such as sand or small stones.
Both models integrate dual anti-tangle main brushes: the V50 Ultra features the HyperStream system with dual brush anchored at one end, whilst the Qrevo Slim uses the DuoDivide design that pushes hair towards the centre for direct suction. Both systems significantly reduce hair tangles, something essential for homes with pets.
Where the Mova sets itself apart is in the side brush. This model includes an extendable side brush, liftable during mopping and anti-tangle. The Roborock also has an extendable side brush, but it doesn't lift during mopping nor does it feature anti-tangle technology. This may mean that the Qrevo Slim's side brush gets wetter during mopping sessions and requires slightly more maintenance.
Mopping
Both robots use two rotating mops for mopping, with side extension that allows better reach to edges. The Mova V50 Ultra also adds the Roboswing system, a swaying movement that slightly introduces the mop under overhangs or furniture. Mop lifting is practically identical: 10.5 mm on the V50 Ultra and 10 mm on the Qrevo Slim, sufficient to climb over thin carpets without wetting them.
The main difference lies in water temperature. The Mova mops with hot water at 55°C, which helps to better dissolve grease and difficult stains. The Roborock uses cold water, although both bases wash the mops with hot water and dry them with hot air.
The V50 Ultra can automatically remove the mops at the base when only vacuuming is needed, avoiding having to do it manually. The Qrevo Slim doesn't offer this function. Both units detect dirt on both the mops and the floor to adjust mopping or repeat dirtier areas.
Navigation System
The Mova V50 Ultra uses retractable LiDAR combined with dual AI camera and front 3D laser sensor. The Roborock Qrevo Slim integrates the StarSight 1.0 system, also with dual AI camera and 3D sensor. Both include LED for night vision and allow remote access to the camera from the app.
The major difference lies in object recognition capability: the V50 Ultra identifies up to 200 different types of obstacles, compared to 73 on the Qrevo Slim. Additionally, the Mova detects curtains, a function that doesn't appear on the Roborock model. This can make a difference in homes with long curtains or many objects on the floor.
The Mova V50 Ultra integrates CleanGenius AI for intelligent cleaning and stain recognition using AI. The Qrevo Slim features SmartPlan 1.0 and RR Mason 11.0 algorithm, although it doesn't specify stain recognition by artificial intelligence.
Autonomy and Battery
The Mova V50 Ultra features a 6,400 mAh battery that offers 220 minutes of autonomy. The Roborock Qrevo Slim has 5,200 mAh with 180 minutes of operation. The 40-minute difference can be relevant in large homes where the robot needs to complete the entire cleaning without intermediate recharges.
With greater battery capacity, the V50 Ultra can cover larger surfaces in a single session, especially useful if vacuuming and mopping are combined in the same run.
Smart Functions
The Mova V50 Ultra can overcome simple steps, although the exact height isn't specified. The Roborock Qrevo Slim overcomes obstacles up to 20 mm, sufficient to pass over thick carpets or small level differences between rooms.
Both models integrate their own voice assistant and are compatible with external assistants such as Alexa or Google Home. Neither includes a robotic arm.
Multifunctional Cleaning Base
Both bases perform auto-emptying of the dust container, mop washing with hot water and drying with hot air. The difference lies in the extras.
The Mova V50 Ultra includes third-generation tray self-cleaning, UV disinfection and dual detergent tank. The Roborock Qrevo Slim has version 1.0 tray self-cleaning, but without UV or detergent tank. UV disinfection helps eliminate bacteria in the base, something to consider in homes with young children or pets.
The V50 Ultra's dust bag has a capacity of 3.2 litres, compared to the Qrevo Slim's 2.7 litres. This means fewer bag changes throughout the year. The clean and dirty water tanks are identical in both: 4 litres and 3.5 litres respectively.
Neither offers integrated plumbing connection nor an optional kit for it.
Dimensions
The Roborock Qrevo Slim stands out for its reduced height: only 82 mm compared to the Mova V50 Ultra's 89.5 mm. Those 7.5 mm of difference can be decisive for passing under sofas, beds or low furniture. The diameter is practically the same: 350 mm on the Mova and 353 mm on the Roborock.
As for the bases, the Qrevo Slim is narrower (340 mm vs 420 mm) but also taller (521 mm vs 470 mm). The V50 Ultra has a wider and deeper base: 420 x 458 mm compared to 340 x 487 mm. It's advisable to measure the available space before deciding.
Real-World User Experience
For large homes, the Mova V50 Ultra offers clear advantages: greater autonomy, more suction power and larger dust bag. The ability to automatically remove the mops makes it easier to alternate between vacuum-only sessions and complete mopping without manual intervention.
The dual detergent tank allows using different products depending on the type of floor or level of dirt, useful if combining surfaces such as parquet and tiles.
In homes with pets, both robots work well thanks to their anti-tangle brushes, although the Mova's greater power can make a difference on carpets where hair accumulates. The V50 Ultra's anti-tangle side brush also reduces maintenance.
The Roborock Qrevo Slim is more suitable for flats with low furniture or spaces where every millimetre of height counts. Its lower autonomy isn't a problem in medium-sized homes. The absence of a detergent tank means adding product manually to the water tank if desired.
Conclusion: Which to Choose?
Choose Mova V50 Ultra if... you live in a large house, have pets or need maximum suction power. Also if you value functions such as mopping with hot water at 55°C, UV disinfection in the base, automatic mop removal and dual detergent tank. The greater object recognition (200 types) provides more precise navigation in homes with many obstacles or long curtains.
Choose Roborock Qrevo Slim if... the priority is passing under low furniture thanks to its 82 mm height. It's a solid option for medium-sized flats where the 180-minute autonomy is sufficient. The narrower base makes it easier to position in tight spaces. Roborock is a world-leading brand with reliable app and good technical support, which guarantees a satisfactory user experience.
