Introduction
The Mova S70 Roller and Mova V50 Ultra represent two distinct approaches to automated floor cleaning within the same manufacturer's range. Whilst the V50 Ultra launched in 2025 as a comprehensive solution with dual rotating mops, the S70 Roller arrives in 2026 introducing a 270mm roller-based mopping system that fundamentally changes how the robot tackles wet cleaning tasks.
These models cater to different user priorities. The S70 Roller focuses on continuous contact mopping through its roller mechanism, paired with enhanced suction power. The V50 Ultra builds around extensive artificial intelligence features, dual cameras, and hot water cleaning capabilities. Understanding which design philosophy suits your home requires examining how these technical differences translate into practical cleaning performance.
Power and Suction
The S70 Roller delivers 28,000 Pa suction, providing a noticeable advantage over the V50 Ultra's 24,000 Pa. This 4,000 Pa difference becomes relevant when dealing with embedded dirt in carpets or stubborn debris in floor crevices. For homes with pets that shed heavily or households with multiple floor types, this extra extraction force helps maintain cleanliness between deep cleaning sessions.
Where the models diverge significantly is brush configuration. The S70 Roller uses a single main brush without elevation capability during mopping. The V50 Ultra employs a dual anti-tangle brush system that lifts when the mops engage, preventing carpet fibres from getting wet during combined cleaning runs. This HyperStream dual brush design actively prevents hair entanglement, which matters considerably in homes with long-haired occupants or pets.
Both models feature extendable and elevating side brushes with anti-tangle properties. This shared capability ensures corner cleaning remains effective across both units, with the extending mechanism reaching into tight spaces that standard side brushes miss.
Mopping
The mopping systems represent the most fundamental distinction between these robots. The S70 Roller's 270mm roller maintains constant contact with floors, rotating continuously to scrub surfaces rather than simply dragging fabric across them. This approach mimics traditional mopping more closely, potentially offering better agitation on stubborn marks.
The V50 Ultra uses dual rotating mops that extend for edge cleaning and incorporate Roboswing movement to reach under furniture edges. These mops lift 10.5mm when encountering carpets, whilst the S70 Roller's system elevates slightly higher at 12mm. In practice, this 1.5mm difference rarely affects performance on standard household rugs.
Temperature makes a substantial difference here. The V50 Ultra heats water to 55°C for floor cleaning, helping dissolve grease and sanitise surfaces more effectively than the S70 Roller's cold water approach. The V50 Ultra also detects dirt on both its mops and the floor itself, triggering additional cleaning passes when needed. The S70 Roller lacks this detection capability, following predetermined cleaning patterns regardless of actual floor condition.
The V50 Ultra can automatically detach its mops at the base when you only need vacuuming, eliminating the need to manually remove them. The S70 Roller requires manual intervention for this task.
Navigation System
The S70 Roller employs CovertSense dToF navigation with a frontal 3D laser sensor for obstacle detection. This provides accurate mapping and reliable navigation, though without visual recognition capabilities. The V50 Ultra combines a retractable LiDAR system with dual AI cameras, LED night vision, and CleanGenius AI processing. This setup recognises up to 200 different objects, identifies pets specifically, detects curtains to avoid entanglement, and allows remote camera access through the app.
For households wanting to check on pets whilst away or verify cleaning progress visually, the V50 Ultra's camera access provides genuine utility. The S70 Roller navigates competently but cannot differentiate between object types or provide visual feedback beyond mapping data.
Battery and Autonomy
The V50 Ultra's 6,400 mAh battery delivers 220 minutes of runtime, covering extensive floor areas before requiring recharge. The S70 Roller's 5,200 mAh capacity represents a smaller power reserve, though specific runtime figures aren't available for direct comparison. The 1,200 mAh difference suggests the V50 Ultra handles larger homes more comfortably in single cleaning sessions, particularly when combining vacuuming and mopping tasks that drain batteries faster than vacuuming alone.
Smart Functions
The S70 Roller climbs obstacles up to 22mm high, managing standard door thresholds and floor transitions without difficulty. The V50 Ultra handles single-step obstacles, though exact height specifications aren't detailed. Both robots integrate with external voice assistants like Alexa and Google Home, but the V50 Ultra additionally includes its own built-in voice assistant for direct interaction without requiring separate smart home infrastructure.
Multifunction Cleaning Base
Both bases automatically empty dust into 3.2-litre bags and wash mops with hot water. They dry mops using heated air to prevent odours and bacterial growth. The S70 Roller's base features a 5-litre clean water tank and 4.5-litre waste water capacity. The V50 Ultra uses a 4-litre clean tank with 3.5-litre waste capacity, requiring slightly more frequent refilling during extended cleaning sessions.
The V50 Ultra's base incorporates third-generation self-cleaning for its washing tray, UV disinfection for sanitising mops, and dual detergent tanks allowing separate cleaning solutions for different floor types or cleaning intensities. The S70 Roller's base lacks UV disinfection and doesn't accommodate detergent dispensing, relying solely on hot water for mop cleaning.
These differences affect maintenance frequency and hygiene levels. The UV disinfection and detergent capability in the V50 Ultra's base provide more thorough mop sanitisation, whilst the S70 Roller's simpler system requires less monitoring of consumables.
Dimensions
The robots measure nearly identically: 350mm diameter with the S70 Roller standing 90mm tall versus the V50 Ultra's 89.5mm height. This half-millimetre difference proves irrelevant for furniture clearance in real-world situations. Both robots fit under standard sofas and bed frames with typical 100mm+ clearances.
Base dimensions differ substantially. The S70 Roller's base measures 340mm wide, 503mm tall, and 255mm deep—a relatively tall, narrow footprint. The V50 Ultra's base spans 420mm wide, 470mm tall, and 458mm deep, occupying considerably more floor space but standing slightly lower. The S70 Roller's compact depth suits placement against walls in tighter spaces, whilst the V50 Ultra's larger footprint accommodates its additional features like UV disinfection and dual detergent tanks.
Real-World Experience
For homes with pets, the V50 Ultra's dual anti-tangle brushes, pet recognition, and dirt detection systems provide tangible advantages. The camera identifies animals to avoid disturbing them, whilst the brush design minimises hair wrap that requires manual cleaning. The S70 Roller's higher suction partially compensates for its single brush design, though you'll likely spend more time removing tangled hair.
The roller mopping system on the S70 Roller suits households prioritising scrubbing action over intelligent adaptation. If you clean relatively predictable floor layouts without many obstacles, the roller's continuous contact delivers consistent results. The V50 Ultra's intelligent features shine in complex environments with varied obstacles, multiple floor types, and unpredictable mess patterns where AI-driven decisions improve outcomes.
Battery capacity matters most in larger properties. The V50 Ultra's extended runtime handles expansive single-level homes or thorough whole-house cleaning cycles without interruption. The S70 Roller may require mid-clean recharging in homes exceeding 150-180 square metres, depending on cleaning intensity and floor types.
Maintenance routines differ noticeably. The V50 Ultra's automatic mop detachment, dual detergent system, and UV disinfection reduce hands-on intervention. You'll refill detergent and occasionally check the self-cleaning system, but daily interaction remains minimal. The S70 Roller requires manual mop removal for vacuum-only sessions and more frequent attention to brush cleaning due to its single-brush design.
Conclusion: Which to Choose?
Choose the Mova S70 Roller if you want maximum suction power and prefer roller-based mopping that provides continuous scrubbing action. This model suits smaller to medium-sized homes with straightforward layouts, where the simpler feature set meets cleaning needs without the complexity of AI systems. The compact base depth fits well in tighter spaces, and the larger water tanks mean less frequent refilling despite the lack of detergent dispensing.
Choose the Mova V50 Ultra if your home benefits from intelligent navigation, particularly with pets, numerous obstacles, or varied floor types. The dual anti-tangle brushes, hot water floor cleaning, dirt detection, and AI recognition justify the investment in larger or more complex living spaces. Remote camera access adds genuine value if you want to monitor cleaning progress or check on pets, whilst the built-in voice assistant simplifies interaction. The extended battery life handles expansive properties comfortably, and the UV disinfection with dual detergent tanks provides superior hygiene for households prioritising sanitisation.
The choice ultimately depends on whether you value raw cleaning power and mechanical simplicity, or prefer intelligent adaptation and comprehensive automation features that reduce ongoing manual intervention.
