Introduction
The Mova S70 Roller and Mova Z50 Ultra represent two distinct approaches to automated floor cleaning from the same manufacturer. The S70 Roller arrives in 2026 with a focus on raw suction power and an innovative roller-based mopping system, whilst the Z50 Ultra from 2025 brings comprehensive AI capabilities and advanced navigation features to the table. Both models feature multifunctional bases that handle the dirty work of cleaning and drying mops, though their approaches to floor care differ significantly.
The S70 Roller suits users seeking maximum suction performance combined with a wider mopping roller, particularly beneficial for larger hard floor areas. The Z50 Ultra targets households wanting intelligent obstacle recognition, remote camera access, and adaptive cleaning powered by artificial intelligence. Understanding which capabilities matter most for your specific home environment makes all the difference when choosing between these two capable machines.
Power and Suction
The S70 Roller delivers 28,000 Pa of suction, substantially more powerful than the Z50 Ultra's 19,000 Pa. This difference becomes noticeable when tackling embedded dirt in carpets or dealing with stubborn debris in floor crevices. For homes with multiple rugs or high-pile carpets, that extra suction capacity can reduce the need for multiple passes.
Where the Z50 Ultra gains ground is with its TriCut 3.0 brush, combining bristles with integrated blades that slice through tangled hair. The S70 Roller uses a simpler roller brush design that may require more frequent maintenance in homes with long-haired residents or shedding pets. The Z50 Ultra also lifts its main brush during mopping, preventing the wet brush from dragging across already-cleaned floors or spreading moisture unnecessarily.
Both machines feature extendable and liftable side brushes with anti-tangle properties, ensuring consistent edge cleaning without the frustration of hair wrapped around brush mechanisms. This shared capability means neither model will disappoint when it comes to reaching skirting boards and corners.
Mopping Performance
The mopping systems reveal fundamentally different philosophies. The S70 Roller employs a 270mm roller with extension capability, offering wider coverage in a single pass. This design excels at consistent moisture distribution across large open floor areas. The Z50 Ultra uses a wide roller paired with a mini side mop for tackling edges, providing targeted cleaning along walls and furniture bases.
Mop lift capability differs significantly: the S70 Roller raises its mop 12mm, whilst the Z50 Ultra manages 7mm. That extra 5mm matters when transitioning onto thicker rugs or crossing room dividers. The higher lift reduces the chance of dragging a damp mop across surfaces you'd prefer to keep dry.
Temperature makes a notable difference here. The Z50 Ultra heats floor-cleaning water to 35°C, helping dissolve greasy residues and sticky spills more effectively than cold water alone. The S70 Roller relies on cold water for floor cleaning, though both models wash their mops with hot water at the base station.
The Z50 Ultra's dirt detection system monitors both mop cleanliness and floor soil levels, automatically adjusting cleaning intensity or triggering additional passes when sensors detect persistent grime. The S70 Roller lacks this adaptive capability, following predetermined cleaning patterns regardless of actual floor condition. For homes with high-traffic areas that accumulate dirt unevenly, the Z50 Ultra's intelligent approach delivers more thorough results without manual intervention.
Navigation System
Navigation technology separates these models considerably. The S70 Roller uses CovertSense dToF with a frontal 3D laser sensor for obstacle detection, providing reliable mapping and collision avoidance. The Z50 Ultra combines a LiDAR turret with dual AI cameras, frontal 3D laser sensors, and LED night vision, creating a comprehensive environmental awareness system that recognises up to 160 different obstacle types.
The dual camera system on the Z50 Ultra identifies specific objects—pets, curtains, shoes, cables—and adjusts cleaning behaviour accordingly. It can recognise your dog or cat and navigate more cautiously around them, reducing stress for anxious animals. The remote camera access lets you check on your home whilst away, adding a security dimension beyond mere floor cleaning.
The S70 Roller's simpler navigation handles structured environments efficiently but lacks the contextual awareness that cameras provide. It won't recognise that the object in its path is your pet's water bowl or distinguish between a sock and a permanent fixture. For households with unpredictable floor clutter or curious pets, the Z50 Ultra's visual intelligence reduces stuck situations and cleaning interruptions.
Battery and Autonomy
Battery capacity favours the Z50 Ultra with 6,400 mAh compared to the S70 Roller's 5,200 mAh. This translates to extended cleaning sessions before returning to base, particularly valuable in larger homes or when deep-cleaning modes consume more power. The additional capacity compensates somewhat for the energy demands of the AI processing and camera systems.
Neither model specifies exact runtime figures, though battery capacity provides a reasonable proxy for comparing endurance. The S70 Roller's higher suction power likely draws more current during intensive vacuuming, potentially offsetting its smaller battery during heavy-duty tasks. In practice, both machines pause to recharge and resume cleaning automatically when tackling areas beyond single-charge capacity.
Intelligent Features
Both robots climb obstacles up to 22mm, handling standard door thresholds and carpet edges without assistance. This shared capability ensures neither model gets stranded moving between rooms with different flooring types.
The Z50 Ultra includes a built-in voice assistant alongside support for external systems like Alexa and Google Home. This native assistant handles cleaning commands and status queries without requiring internet connectivity or third-party services. The S70 Roller supports external voice assistants but lacks its own onboard system, requiring network access for voice control functionality.
The CleanGenius AI system in the Z50 Ultra analyses floor types, dirt levels, and room usage patterns to optimise cleaning schedules and methods automatically. This learning capability means the robot improves its efficiency over time, concentrating effort where it's actually needed rather than following rigid routines. The S70 Roller follows programmed instructions effectively but doesn't adapt based on observed conditions.
Multifunctional Base Station
Both bases handle automatic dust emptying, mop washing with hot water, and mop drying with warm air. These shared capabilities mean neither model demands frequent manual maintenance—the bases manage the unpleasant tasks of emptying dirt and cleaning mop pads.
The S70 Roller's base includes automatic tray cleaning, washing the area where mops rest after cleaning. This self-maintenance feature reduces odour buildup and keeps the base station hygienic without manual scrubbing. The Z50 Ultra requires occasional manual tray cleaning to maintain freshness.
Storage capacity differs notably. The S70 Roller provides a 5-litre clean water tank and 4.5-litre waste water container, paired with a 3.2-litre dust bag. The Z50 Ultra reverses the priority with a 4.5-litre clean water tank, 4-litre waste water container, but a larger 4-litre dust bag. The S70 Roller's larger water tanks suit homes with extensive hard flooring that requires frequent mopping, whilst the Z50 Ultra's bigger dust bag benefits carpet-heavy environments.
The Z50 Ultra includes a detergent dispenser that automatically adds cleaning solution during mop washing, maintaining consistent cleaning chemistry without manual dosing. The S70 Roller lacks this convenience, relying on water alone unless you manually add detergent to the tank.
Dimensions
Height becomes crucial for furniture clearance. The S70 Roller measures just 90mm tall, slipping beneath most sofas, beds, and low-clearance furniture with ease. The Z50 Ultra stands 111mm high—still reasonable, but that extra 21mm prevents access under lower furniture pieces. If your home features low-profile beds or minimalist furniture, the S70 Roller's slimmer profile expands cleanable floor area significantly.
Both robots share a 350mm diameter, navigating standard doorways and furniture arrangements without difficulty. The real dimensional difference appears in the base stations. The S70 Roller's base measures 340mm wide, 503mm tall, and just 255mm deep—a remarkably compact footprint. The Z50 Ultra's base spans 390mm wide, 545mm tall, and 463.3mm deep, requiring substantially more floor space. For flats or homes with limited utility areas, the S70 Roller's space-efficient base proves easier to accommodate discreetly.
Real-World Usage Experience
The S70 Roller excels in homes prioritising powerful suction and compact storage. Its 90mm height accesses cleaning zones that taller robots simply can't reach, reducing the need to manually vacuum under furniture. The wider mopping roller covers floor area efficiently, though the cold water system works best on routine maintenance rather than tackling dried-on spills. The simpler navigation handles predictable floor layouts reliably, making it suitable for tidy homes without excessive clutter.
Homes with pets benefit more from the Z50 Ultra's TriCut brush and pet recognition capabilities. The brush design manages hair better, whilst the camera system navigates around animals without startling them or getting stuck on pet accessories. The hot water mopping at 35°C proves more effective against paw prints, food spills, and the general grime that accompanies animal companionship. Remote camera access lets you check on pets whilst away, adding peace of mind beyond cleaning performance.
For larger homes with mixed flooring, the Z50 Ultra's bigger battery and intelligent dirt detection ensure thorough coverage without repeated manual interventions. The system concentrates effort where sensors detect actual dirt rather than blindly following patterns. Smaller flats with predominantly hard floors suit the S70 Roller's powerful suction and generous water capacity, particularly when storage space for the base station is limited.
