Introduction
The Roborock Qrevo Curv 2 Flow arrives in February 2026 as one of the latest additions to Roborock's premium range, whilst the Mova V50 Ultra launched in 2025 representing Mova's high-end offering. Both robots feature multifunctional bases with hot water washing and hot air drying, positioning themselves firmly in the advanced segment of the market. The Qrevo Curv 2 Flow distinguishes itself with a 270mm roller mop system, whilst the V50 Ultra opts for dual rotating mopas and includes hot water floor cleaning at 55°C. These are comprehensive solutions designed for users seeking minimal intervention in their cleaning routines.
The choice between these models will largely depend on specific priorities: the Roborock brings its established reputation and unique roller design, whereas the Mova offers higher suction power, a slimmer profile, and additional features like UV disinfection and dual detergent tanks.
Power and Suction
The Mova V50 Ultra delivers 24,000 Pa of suction power compared to the Roborock Qrevo Curv 2 Flow's 20,000 Pa. That's a noticeable difference on paper, particularly for homes with thick carpets or heavy pet hair. In practice, this extra muscle should translate to more effective debris pickup in demanding conditions.
Both models feature anti-tangle main brushes, though they employ different approaches. The Roborock uses its DuoDivide Antienredos system, which channels hair towards the central suction point to minimise tangles. The Mova V50 Ultra relies on a dual brush anti-tangle design. Both systems elevate the main brush during mopping to prevent contamination.
The side brush configuration reveals an interesting contrast. The Roborock has a dual anti-tangle side brush that lifts during mopping but doesn't extend. The Mova V50 Ultra includes an extendable side brush alongside its lifting capability, allowing it to reach deeper into corners and edges. This makes the Mova potentially more thorough when tackling perimeter dirt.
Mopping
Here's where these robots diverge significantly. The Roborock Qrevo Curv 2 Flow employs a 270mm roller mop with edge extension capability. This roller design provides consistent pressure and continuous cleaning across the entire width. The Mova V50 Ultra uses dual rotating mopas with edge extension and includes a movement system for enhanced border coverage.
Mop elevation differs between the two. The Roborock achieves 15mm of lift plus additional chassis elevation, creating substantial clearance for transitioning onto carpets. The Mova manages 10.5mm of elevation, which is still adequate for most domestic carpets but less generous.
The Mova V50 Ultra heats water to 55°C for floor cleaning, which can help dissolve stubborn stains and improve hygiene. The Roborock uses cold water for floor mopping. Both models wash their mopas with hot water at the base and dry them with hot air to prevent odours and bacterial growth.
A practical advantage for the Mova: it automatically removes its mopas at the base when you want to vacuum only, eliminating manual intervention. The Roborock requires you to handle this yourself. Both robots detect dirt on their mopas and on the floor, adjusting their cleaning intensity accordingly.
Navigation System
The Roborock Qrevo Curv 2 Flow features a 3D LiDAR turret for mapping, whilst the Mova V50 Ultra uses retractable LiDAR. Both include frontal 3D laser sensors, AI cameras, and LED lighting for night vision. The Mova actually incorporates dual AI cameras, potentially offering more comprehensive object recognition.
Both robots recognise up to 200 different obstacles and can identify pets. The Mova V50 Ultra adds curtain detection to its repertoire, which the Roborock doesn't specifically list. Both allow remote camera access, useful for checking on your home or pets whilst you're away.
The Roborock runs SmartPlan 3.0 for intelligent cleaning, whilst the Mova employs CleanGenius AI. Both systems analyse your home and adapt cleaning patterns, recognising stains and adjusting their approach automatically.
Battery and Autonomy
The Mova V50 Ultra packs a larger 6,400 mAh battery compared to the Roborock's 5,200 mAh. Interestingly, despite the bigger battery, the Roborock achieves 242 minutes of runtime against the Mova's 220 minutes. This suggests the Roborock operates more efficiently, likely due to optimised power management or less energy-intensive components.
For most homes, both runtimes are more than sufficient. Even large properties can typically be covered in a single session with either robot, and both will automatically return to their bases to recharge if needed before resuming.
Smart Functions
The Roborock Qrevo Curv 2 Flow can climb obstacles up to 20mm high, whilst the Mova V50 Ultra handles simple steps up to 20mm. Both figures are impressive and mean these robots can transition between rooms with different floor levels or climb over door thresholds without assistance.
Both models include their own voice assistants as well as compatibility with external systems like Alexa and Google Home. This provides flexibility in how you control them, whether through their dedicated apps, built-in voice commands, or your existing smart home ecosystem.
Multifunctional Cleaning Base
Both bases auto-empty the dust bin, wash mopas with hot water, and dry them with hot air. They also feature automatic tray cleaning to maintain hygiene within the base itself. The Mova V50 Ultra specifies its third-generation tray cleaning system.
The Mova distinguishes itself with UV disinfection, which the Roborock doesn't offer. Additionally, the Mova includes dual detergent tanks, allowing you to use different cleaning solutions for various floor types or cleaning scenarios. The Roborock has no detergent dispenser.
The Mova's dust bag capacity is 3.2 litres compared to the Roborock's 2.7 litres. Both have 4-litre clean water tanks and 3.5-litre dirty water tanks, providing ample capacity for extended cleaning sessions without manual refilling.
Neither robot offers integrated pipe connection or an optional kit for plumbing integration, so you'll need to manually refill and empty the tanks periodically.
Dimensions
The height difference is dramatic and functionally significant. The Roborock Qrevo Curv 2 Flow stands 119mm tall, whilst the Mova V50 Ultra measures just 89.5mm. That 29.5mm difference means the Mova can slip under considerably more furniture. If you have low-clearance sofas, beds, or cabinets, the Mova will access spaces the Roborock simply cannot reach.
Diameter is nearly identical: 353mm for the Roborock versus 350mm for the Mova. Both will navigate standard doorways and furniture arrangements without difficulty.
The bases have similar footprints. The Roborock's base measures 450mm in all dimensions (width, height, depth), forming a cube-like shape. The Mova's base is slightly narrower at 420mm wide but taller at 470mm and deeper at 458mm. You'll need to ensure adequate space for either base, preferably in a location with easy access and near a power socket.
Real-World Usage Experience
For homes with pets, both robots offer strong credentials. The Mova's higher suction power gives it a theoretical edge on embedded pet hair, whilst both feature anti-tangle brush systems that reduce maintenance. The Mova's extendable side brush might capture more hair along skirting boards.
If you have furniture with limited clearance underneath, the Mova V50 Ultra's slimmer 89.5mm profile becomes a decisive advantage. It can clean areas the Roborock physically cannot access, reducing the need for manual intervention.
The Roborock's roller mop system provides consistent, even pressure across its width, which some users prefer for thorough mopping. The Mova's dual rotating mopas with hot water floor cleaning at 55°C offer superior stain removal and hygiene, particularly useful in kitchens or homes with young children.
The Mova's automatic mop removal at the base simplifies switching between vacuum-only and mop-and-vacuum modes. The Roborock requires manual mop removal, which isn't onerous but does require a moment of your time.
For larger homes, the Roborock's slightly longer runtime and efficient battery usage might prove beneficial, though both robots comfortably handle substantial floor areas. The Mova's larger dust bag means slightly less frequent bag changes.
Conclusion: Which Should You Choose?
Choose the Roborock Qrevo Curv 2 Flow if: you value the brand's established reputation and prefer a roller mop system. It's ideal if you don't need hot water floor cleaning and your furniture has adequate clearance. The longer runtime and efficient battery management suit larger properties, and the 15mm mop lift with chassis elevation provides excellent carpet protection. This is a solid choice for those who prioritise Roborock's proven reliability and don't require detergent dispensing.
Choose the Mova V50 Ultra if: you want maximum suction power and the ability to clean under low furniture. The 89.5mm height is genuinely transformative for accessing tight spaces. Hot water floor cleaning at 55°C, UV disinfection, and dual detergent tanks deliver superior hygiene and stain removal. The extendable side brush improves edge cleaning, and automatic mop removal at the base adds convenience. This robot suits homes with pets, young children, or anyone prioritising thorough disinfection and minimal manual intervention. The larger battery and dust bag capacity are welcome bonuses, even if runtime is slightly shorter.
