Introduction
The Roborock Qrevo S Pro and the Roborock S8 MaxV Ultra represent two different generations within the catalogue of the world's leading robot vacuum brand. The S8 MaxV Ultra belongs to the 2024 generation and is positioned as a high-end model with advanced artificial intelligence. The Qrevo S Pro arrives in 2026 with a different philosophy: raw suction power and optimisations in the mopping system, although sacrificing some intelligent functions present in its predecessor.
Both units integrate a complete multifunction base with auto-emptying, mop washing and drying, which guarantees minimal maintenance. The choice between one or the other will depend on whether you prioritise suction power and rotary mopping, or prefer a more intelligent ecosystem with visual recognition and integrated voice assistant.
Power and Suction
The most striking difference between these Roborock models is the suction power. The Qrevo S Pro reaches 18,500 Pa, almost doubling the 10,000 Pa of the S8 MaxV Ultra. This figure marks an important generational leap and translates into better capacity to extract ingrained dirt from carpets and tile joints.
The brushing system adopts opposing philosophies. The S8 MaxV Ultra features the double DuoDivide brush, specifically designed to push hair and strands towards the central suction gap, significantly reducing tangles. The Qrevo S Pro opts for a single, more traditional brush, although it compensates with an anti-tangle side brush that the S8 MaxV Ultra does not incorporate.
Where the S8 MaxV Ultra takes the advantage is in the versatility of its brushes. The main brush can be lifted during mopping, avoiding contaminating mops with collected dust. Additionally, its side brush is extendable, which allows better sweeping of corners and hard-to-reach areas. The Qrevo S Pro does not have either of these two lifting or extension functions.
In homes with pets or people with long hair, the double brush of the S8 MaxV Ultra is more practical for daily maintenance, whilst the superior power of the Qrevo S Pro can make a difference on high-pile carpets.
Mopping
The mopping system presents important technical differences. The Roborock Qrevo S Pro uses two rotating mops, a design that generates constant friction on the floor and is effective for stuck-on stains. The S8 MaxV Ultra opts for a vibratory mop, complemented with an extendable mini side mop that allows better mopping of edges and corners.
Mop lift shows a significant difference: the S8 MaxV Ultra can lift them up to 20 mm, double the 10 mm of the Qrevo S Pro. This greater lift better protects carpets during mopping and prevents wet mops from dragging over textile surfaces.
The S8 MaxV Ultra incorporates dirt detection both on the mops themselves and on the floor, which allows it to automatically go over areas it detects as especially dirty or to rewash the mops when it considers it necessary. The Qrevo S Pro lacks this intelligent function, performing a more standard mopping without automatic adaptation.
Both models feature mop washing with hot water in the base and drying with hot air, guaranteeing hygiene and absence of bad odours. The difference lies in the intelligence applied during the mopping process, where the S8 MaxV Ultra offers greater sophistication.
Navigation System
Here we find the most marked contrast in this robot vacuum comparison. The Roborock S8 MaxV Ultra integrates a complete navigation system with 3D LiDAR turret, dual camera with artificial intelligence and front 3D laser sensor. This combination allows it to recognise up to 73 different types of obstacles, including pets, and adapt its cleaning behaviour according to what it detects.
The Qrevo S Pro is limited to the 3D LiDAR turret with basic obstacle avoidance, dispensing with cameras and front laser sensors. It cannot recognise specific objects or pets, which reduces its capacity for intelligent adaptation to the environment.
Remote camera access, available only on the S8 MaxV Ultra, allows monitoring of the home from the mobile app. The night vision LED facilitates this function even in low light. The Qrevo S Pro does not offer any of these video surveillance possibilities.
Both robots use SmartPlan intelligent cleaning systems, although the S8 MaxV Ultra uses version 1.0 and the Qrevo S Pro updates to SmartPlan 2.0. Stain recognition using AI is present only in the S8 MaxV Ultra, which also specifies using the RR Mason 11.0 algorithm.
Autonomy and Battery
The battery capacity is identical in both: 5,200 mAh providing 180 minutes of autonomy. This figure allows covering large homes in a single cleaning session without the need for intermediate recharges.
Despite the Roborock Qrevo S Pro offering almost double the suction power, it maintains the same autonomy as the S8 MaxV Ultra, which suggests energy optimisations in motor and system management. In practice, either of the two can handle large surfaces without battery problems.
Intelligent Functions
The ability to overcome obstacles is identical: both robots can negotiate steps of up to 20 mm, sufficient to move between rooms with small level changes or climb onto thick carpets.
The big difference lies in the own voice assistant. The S8 MaxV Ultra integrates one that allows direct interaction with the robot through voice commands, in addition to being compatible with external assistants such as Alexa or Google Home. The Qrevo S Pro only supports these external assistants, without its own response capability.
This function can be especially practical for activating spot cleaning or checking the robot's status without needing to open the mobile app.
Multifunction Cleaning Base
Both units share the essential functions of their multifunction bases: auto-emptying of the dust container, mop washing with hot water and drying with hot air. These features guarantee weeks of autonomy without manual intervention.
The main difference is in the detergent tank, present only in the S8 MaxV Ultra. This tank allows adding cleaning product that is automatically dosed during mop washing, improving mopping effectiveness. The Qrevo S Pro works exclusively with water.
In terms of capacities, the Qrevo S Pro offers a slightly larger dust bag: 2.7 litres versus the 2.5 litres of the S8 MaxV Ultra. The clean and dirty water tanks are identical: 4 litres and 3.5 litres respectively.
Neither includes auto-cleaning of the washing tray, UV disinfection or connection to water pipes, functions that remain reserved for higher-end models or future versions.
Dimensions
The diameter of both robots is identical: 353 mm. The difference is in the height, where the Qrevo S Pro measures 96.5 mm versus the 103 mm of the S8 MaxV Ultra. Those 6.5 mm of difference can be decisive for getting under low furniture, sofas or beds with little clearance from the floor.
The base dimensions show different designs. The Qrevo S Pro is more compact in width (340 mm versus 409 mm) but taller (519 mm versus 470 mm) and deeper (487 mm versus 419 mm). It's advisable to measure the available space before deciding, especially if you plan to place the base in a tight space.
Weight is not specified in the table for either model.
Real-World Usage Experience
For large homes, both robots offer sufficient autonomy thanks to their 180 minutes of battery. The superior power of the Qrevo S Pro can make a difference in houses with carpets or lots of textile surface where greater suction capacity is required.
If you live with pets, the S8 MaxV Ultra presents clear advantages: its double DuoDivide brush reduces hair tangles, it recognises animals to avoid unpleasant surprises and its camera allows locating them remotely. The Qrevo S Pro partially compensates with its anti-tangle side brush, but lacks specific recognition.
Regarding mopping, the rotating mop system of the Qrevo S Pro generates greater mechanical friction, useful for dried stains. The S8 MaxV Ultra counters with intelligence: it detects dirt, extends its mini side mop for edges and lifts the mops higher to protect carpets. Additionally, its detergent tank improves results on greasy floors.
For those seeking absolute convenience without intervention, the S8 MaxV Ultra is more complete: it doses detergent automatically, adapts mopping according to detected dirt and allows remote surveillance. The Qrevo S Pro requires greater supervision but offers superior raw power.
The reduced height of the Qrevo S Pro facilitates cleaning under low furniture, a detail that can be decisive depending on your home's configuration.
Conclusion: Which to Choose?
Choose the Roborock Qrevo S Pro if: you prioritise maximum suction power and have high-pile carpets or lots of textile surface. Also if you need a lower robot to access under furniture with little height and prefer a rotating mop mopping system. It's suitable for those seeking an effective robot vacuum without the need for surveillance functions or advanced object recognition.
Choose the Roborock S8 MaxV Ultra if: you value artificial intelligence applied to cleaning and live with pets that the robot must recognise and avoid. Its visual navigation system, recognition of 73 obstacles, remote camera access and own voice assistant make it the best robot vacuum for those seeking total autonomy and intelligent functions. The automatic detergent tank and dirt detection optimise mopping without manual intervention. Its extendable mini mop improves results on edges and corners, although you sacrifice some raw suction power compared to the Qrevo S Pro.
