Introduction
The Roborock Qrevo Curv 2 Flow and the Mova S70 Roller represent two high-end propositions within the robot vacuum market of 2025, both launched in the first quarter of 2026. Both units integrate a mopping system with 270 mm roller, multifunctional base with mop washing and drying using hot water and air, and advanced navigation capabilities. However, there are significant technical differences worth analysing before deciding which best suits each home.
The Roborock model is aimed at users seeking maximum artificial intelligence and remote control, whilst the Mova option stands out for its superior suction power and greater storage capacity in the base.
Power and Suction
The most striking difference in this section is marked by suction power. The Mova S70 Roller reaches 28,000 Pa, a figure that exceeds the Roborock Qrevo Curv 2 Flow by 8,000 Pa. This advantage can translate into better performance on thick carpets or in homes with pets that shed a lot of hair.
The main brushing system differs substantially. The Roborock unit integrates the DuoDivide anti-tangle brush, designed to push hair towards the central suction gap and reduce tangles. The Mova uses a simple silicone brush, which also minimises tangles albeit with a different approach. Both systems prove effective, although the DuoDivide tends to show advantages in homes with long hair or pets with abundant fur.
The Qrevo Curv 2 Flow incorporates main brush lifting during mopping, a feature absent on the Mova. This allows the Roborock robot to prevent the brush from touching the wet floor, which in practice improves the hygiene of subsequent brushing.
Regarding the side brush, the Mova S70 Roller features extension to better reach corners, whilst the Roborock lacks this function. Both models lift the side brush during mopping and have anti-tangle design, with double brush in the case of the Roborock.
Mopping
Both robots use a 270 mm roller, a system that offers better floor contact than traditional rotating mops. Both extend the mops to reach edges, an important feature for achieving complete mopping right up to the walls.
Mop lifting marks a technical difference: the Roborock Qrevo Curv 2 Flow lifts up to 15 mm with additional coverage system, versus the 12 mm of the Mova S70 Roller. Those extra 3 mm allow the Roborock model to pass over medium-pile carpets without wetting them, expanding its versatility in homes with different floor types.
The dirt detection system represents an exclusive advantage of the Qrevo Curv 2 Flow. This robot identifies dirt both on the mops themselves and on the floor, adjusting the washing and scrubbing process as necessary. The Mova lacks these functions, which means a more standard mopping process without automatic adaptation to the level of dirt.
The bases of both units wash the mops with hot water and dry them with hot air, guaranteeing hygiene and preventing bad odours. Neither automatically removes the mops at the base to perform vacuum-only tasks.
Navigation System
The Roborock Qrevo Curv 2 Flow integrates 3D LiDAR turret combined with AI camera, front 3D laser sensor and night vision LED. This assembly enables recognition of up to 200 different types of obstacles, including pets specifically. The camera offers remote access, making it possible to monitor the home from the mobile app.
The Mova S70 Roller uses CovertSense dToF navigation with front 3D laser sensor, but without AI camera. It avoids obstacles effectively, although it doesn't specify the number of recognisable objects nor offers specific pet identification. Neither does it allow remote camera access nor feature a front LED.
For homes with pets, the Roborock provides greater peace of mind by recognising and avoiding them specifically. Remote camera access proves useful for those wishing to check the state of the home during cleaning sessions.
The Qrevo Curv 2 Flow also incorporates SmartPlan 3.0, an intelligent cleaning system that plans optimised routes, and stain recognition via AI. The Mova doesn't include these advanced intelligence functions.
Autonomy and Battery
Both robots feature a 5,200 mAh battery. The Roborock Qrevo Curv 2 Flow declares 242 minutes of autonomy, a figure more than sufficient for medium-large sized homes. The Mova S70 Roller doesn't specify battery duration in the available data, although the identical capacity suggests similar performance.
In practice, with 242 minutes the Roborock unit can cover large surfaces in a single cycle, minimising interruptions for recharging.
Smart Functions
The ability to overcome obstacles differs slightly: the Mova S70 Roller reaches 22 mm, versus the 20 mm of the Roborock Qrevo Curv 2 Flow. Those additional 2 mm can make the difference in homes with thick carpets or raised thresholds between rooms.
The Roborock incorporates its own voice assistant, allowing voice control without depending exclusively on Alexa or Google Home. The Mova lacks its own assistant, although it is compatible with the usual external assistants. Both models offer this basic compatibility.
Multifunctional Cleaning Base
Both bases perform auto-emptying of the dust container, washing and drying of mops with hot water and air, and self-cleaning of the washing tray. Neither integrates UV disinfection, detergent tank nor connection to plumbing.
The differences are concentrated in storage capacities. The Mova S70 Roller offers a 3.2-litre dust bag versus the Roborock's 2.7, a 5-litre clean water tank versus 4, and a 4.5-litre dirty water tank versus 3.5. These higher figures translate into greater base autonomy: fewer manual emptyings and refills, especially relevant in large homes or with pets that generate a lot of dirt.
For those who prioritise maintenance convenience, the Mova reduces the frequency of manual intervention.
Dimensions
The Mova S70 Roller measures 90 mm in height, versus the 119 mm of the Roborock Qrevo Curv 2 Flow. This difference of nearly 3 centimetres is significant: the Mova accesses more easily under furniture, sofas or low beds. In homes where furniture leaves little space underneath, this advantage can determine which areas get cleaned and which remain inaccessible.
The diameter barely varies: 350 mm on the Mova versus 353 mm on the Roborock, an irrelevant difference in practice.
The bases present different configurations. The Roborock's forms a cube of 450 x 450 x 450 mm, whilst the Mova's is taller and narrower: 340 mm wide, 503 mm high and 255 mm deep. Depending on available space, one or other geometry may fit better. The Mova's base occupies less floor surface, although it requires more height.
Real-World Usage Experience
In homes with pets, the Roborock Qrevo Curv 2 Flow provides clear advantages: specific animal recognition, DuoDivide anti-tangle brush and dirt detection that intensifies washing when it detects more hair or stains. The Mova counters with greater suction power, useful for vacuuming hair embedded in carpets.
For large homes, the Mova S70 Roller stands out for the larger capacity tanks in the base, reducing maintenance tasks. The Roborock offers greater declared robot autonomy (242 minutes), although both should cover large surfaces without problems.
If the home includes many low pieces of furniture, the reduced height of the Mova (90 mm) facilitates access to areas the Roborock wouldn't reach. This can make the difference between complete or partial cleaning.
Those who value remote control and home monitoring will appreciate the camera with remote access of the Qrevo Curv 2 Flow. The SmartPlan 3.0 system and stain recognition add intelligence that the Mova doesn't match, although the latter compensates with brute power and ability to overcome obstacles up to 22 mm.
Both mop with roller and extend mops to edges, guaranteeing similar results on hard floors. The Roborock's superior lifting (15 mm) better protects carpets during mopping.
Conclusion: Which to Choose?
Choose the Roborock Qrevo Curv 2 Flow if: you're seeking maximum artificial intelligence with recognition of 200 obstacles and pets, you value remote camera access for home monitoring, you prefer the DuoDivide anti-tangle brush and dirt detection that adapts mopping automatically. Also if you need greater mop lifting (15 mm) to protect carpets or appreciate having your own voice assistant. It's the option for those who prioritise advanced technology and total control from the app.
Choose the Mova S70 Roller if: you prioritise high suction power (28,000 Pa) for carpets or difficult pet hair, you need to access under very low furniture thanks to its 90 mm height, you value greater base autonomy with larger tanks (less manual maintenance), or you're looking to overcome obstacles up to 22 mm. The extendable side brush improves sweeping in corners. Ideal for large homes with low furniture and users who prefer power and capacity over advanced AI functions.
