Introduction
The Mova S70 Roller and the Roborock Qrevo Curv represent two different approaches within the robot vacuum segment with multifunction base. The Mova model will arrive in 2026 with a design that incorporates a 270 mm roller for mopping, whilst the Roborock Qrevo Curv, available since 2024, opts for the dual spinning mop system that has established the brand as a reference in the sector.
Although they share advanced functions such as hot water mop washing and hot air drying, the differences in navigation, power and intelligent capabilities mark distinct usage profiles. The Mova stands out in raw power and base capabilities, whilst the Roborock excels in artificial intelligence and autonomy.
Power and Suction
The difference in suction power is significant. The Mova S70 Roller reaches 28,000 Pa, a considerable figure that exceeds the Roborock Qrevo Curv by almost 10,000 Pa. In practice, this translates to greater capacity to extract embedded dirt from carpets or vacuum heavy debris.
The brushing system shows different approaches. The Roborock incorporates the DuoDivide anti-tangle brush, specifically designed to push hair towards the central gap and minimise tangles. The Mova is equipped with a simple brush, although both models include an anti-tangle and extendable side brush to improve cleaning in corners.
A practical difference: the main brush of the Roborock Qrevo Curv lifts during mopping, preventing it from getting wet and facilitating maintenance. The Mova S70 Roller does not have this function, but does lift the side brush, a feature that the Roborock lacks. For households with pets, the Qrevo Curv's DuoDivide system offers clear advantages in hair management.
Mopping
Here we find one of the most notable differences. The Mova S70 Roller integrates a 270 mm roller for mopping, a system that covers more contact surface with the floor and can be effective on adhered dirt. The Roborock Qrevo Curv maintains the dual spinning mop system, proven and efficient in cleaning hard floors.
Both extend the mops to better reach edges and lift the mopping system when they detect carpets: 12 mm in the Mova, between 10 and 20 mm in the Roborock. This variable capability of the Qrevo Curv allows it to adapt to different carpet heights.
The Roborock incorporates dirt detection both on the mops and on the floor, which allows it to reinforce cleaning in dirtier areas or rewash the mops when necessary. The Mova S70 Roller does not have this function. Both wash the mops with hot water and dry them with hot air, guaranteeing hygiene and avoiding bad odours. Tray self-cleaning is present in both, although the Roborock specifies that it features version 2.0 of this system.
Navigation System
Navigation marks a substantial difference between both units. The Roborock Qrevo Curv integrates dual camera with artificial intelligence, recognises up to 62 different obstacles, identifies pets and allows remote camera access. Additionally, it includes LED for night vision and the SmartPlan 2.0 system with RR Mason 11.0 algorithm.
The Mova S70 Roller uses the CovertSense dToF system with front 3D laser sensor, sufficient for mapping and avoiding obstacles, but without cameras or intelligent recognition capabilities. It does not identify pets nor allow remote viewing. For users who value home monitoring or have pets whose behaviour they want to supervise, the Roborock offers functionalities that the Mova simply does not have.
Both detect obstacles, but the user experience differs: the Qrevo Curv learns and optimises routes with greater precision thanks to its AI.
Autonomy and Battery
The Roborock Qrevo Curv is equipped with a 6,400 mAh battery that provides 240 minutes of autonomy. The Mova S70 Roller features 5,200 mAh, although the duration in minutes is not specified. The 1,200 mAh difference clearly favours the Roborock, especially in large homes where autonomy is decisive for completing cleaning without intermediate recharges.
For homes over 150 square metres, this advantage of the Qrevo Curv can make the difference between a complete clean in a single cycle or needing several sessions.
Intelligent Functions
The Mova S70 Roller overcomes obstacles up to 22 mm in height. The Roborock Qrevo Curv goes further with its simple step system that allows it to navigate uneven surfaces with greater versatility, although the exact height is not specified.
The Roborock includes its own voice assistant in addition to compatibility with Alexa and Google Home. The Mova S70 Roller only offers compatibility with external assistants. This may be relevant for those seeking to control the robot through voice commands without depending on additional devices.
Multifunction Cleaning Base
Both robots include a complete multifunction base: they auto-empty the dust bin, wash the mops with hot water, dry them with hot air and perform tray self-cleaning. Neither incorporates a detergent tank nor connection to plumbing.
The differences lie in the capacities. The Mova S70 Roller stands out with a 3.2-litre dust bag, 5-litre clean water tank and 4.5-litre dirty water tank. The Roborock Qrevo Curv offers 2.5 litres for the bag, 4 litres of clean water and 3 litres of dirty water. For large homes or users who prefer to reduce maintenance, the Mova's tanks allow greater autonomy between emptying and refilling.
Dimensions
The Mova S70 Roller measures 90 mm in height, which facilitates access under low furniture, beds or sofas. The Roborock Qrevo Curv reaches 103 mm, a 13 mm difference that may limit its passage in tight spaces. The diameter is practically identical: 350 mm versus 352 mm.
As for the base, the Mova is more compact: 340 mm wide, 503 mm high and 255 mm deep. The Roborock has a cubic base of 450 mm in all dimensions, occupying more floor space. If available space is limited, these measurements are worth considering.
The robot's internal tanks also differ. The Mova carries 240 ml of dust and 150 ml of water. The Roborock is equipped with 325 ml of dust but only 80 ml of water. This does not greatly affect actual use, as both have a multifunction base that manages these aspects automatically.
Real-World Usage Experience
For large homes, the Roborock Qrevo Curv offers clear advantages: greater battery autonomy, intelligent navigation that optimises routes and the ability to complete extensive cleaning without intervention. Its dual spinning mop system is efficient and the DuoDivide brush minimises maintenance in households with pets.
The Mova S70 Roller provides superior raw power, useful on thick carpets or difficult dirt. Its reduced height allows access to spaces where the Roborock cannot enter. The base tanks are more generous, reducing maintenance frequency. However, the absence of cameras and intelligent dirt detection limits its adaptability.
In households with pets, the Roborock wins due to its anti-tangle brush, animal recognition and remote supervision capability. The Mova may require more manual brush cleaning. For exclusively hard floors without carpets, both perform well, although the Mova's roller system may offer more intensive mopping on adhered stains.
Conclusion: Which to Choose?
Choose the Mova S70 Roller if... you seek maximum suction power, you have low furniture that requires a robot with lower height, you value large tanks in the base to minimise maintenance, or you prefer the roller system for mopping. Also if your home is not excessively large and you do not need advanced AI functions.
Choose the Roborock Qrevo Curv if... you have a large house where autonomy is critical, you live with pets and want to minimise hair tangles, you value intelligent navigation with obstacle recognition and remote supervision, or you seek a robot that learns and optimises cleaning routes. Its spinning mop system and dirt detection guarantee consistent results with minimal intervention.
For the relationship between performance and long-term ease of use, the Roborock Qrevo Curv offers a more balanced package and intelligent functions that make a difference in day-to-day use. The Mova S70 Roller stands out in power and base capacity, aspects that may be decisive depending on each household's priorities.
