Introduction
The Roborock Qrevo Master and the Roborock S8 MaxV Ultra represent two high-end propositions launched in 2024 by the world's leading brand in robot vacuum cleaners. Both units share the same suction power of 10,000 Pascals and a 5,200 mAh battery, which places them in the premium segment of the market. However, they present important differences in their mopping system, base dimensions and some specific functions that may tip the balance depending on each household's needs.
The Qrevo Master opts for a rotating mop system, whilst the S8 MaxV Ultra uses a vibrating mop. This difference marks two distinct mopping philosophies that are worth analysing in detail.
Power and Suction
Both models share identical suction power of 10,000 Pascals, a figure that places them amongst the most powerful robots on the current market. This capacity is especially useful in homes with carpets or pets that shed a lot of hair.
The brushing system is practically identical. Both incorporate Roborock's DuoDivide double brush, specifically designed to reduce hair tangles by pushing debris towards the central suction gap. This type of brush makes a difference in homes with long-haired pets.
Both the Qrevo Master and the S8 MaxV Ultra lift the main brush during mopping, which prevents it from getting unnecessarily wet and ensures more efficient mopping. The side brush is extendable in both cases, improving cleaning in corners and edges. Neither model incorporates side brush lift nor a specific anti-tangle system for this component.
Mopping
Here we find the most significant difference between these robot vacuum cleaners. The Roborock Qrevo Master uses rotating mops, a system that applies constant pressure whilst rotating on the floor. The S8 MaxV Ultra, on the other hand, employs a vibrating mop with an additional mini side mop that allows better reach to edges and corners.
Mop lift differs notably: 10 mm on the Qrevo Master compared to 20 mm on the S8 MaxV Ultra. This height difference can be decisive if you have medium or high pile carpets, as the S8 MaxV Ultra will avoid them with greater clearance during mopping.
Both bases wash the mops with hot water, which improves the removal of grease and adhered dirt. Drying is also carried out with hot air on both models, speeding up the process and reducing the possibility of bad odours.
The Qrevo Master incorporates self-cleaning of the washing tray, a function that reduces manual maintenance of the base. The S8 MaxV Ultra does not include this feature, but compensates with a specific detergent tank that automatically dispenses during mop washing. Neither allows automatic removal of mops at the base to perform vacuuming tasks only.
Both detect dirt on both the mops and the floor, activating additional washing or scrubbing cycles when necessary. However, the S8 MaxV Ultra adds AI stain recognition, which allows it to identify especially dirty areas and treat them with greater intensity.
Navigation System
Both units mount LiDAR 3D turret and dual camera with artificial intelligence. The front 3D laser sensor is present on both, allowing precise detection of obstacles in real time.
The difference lies in the number of objects they can recognise: the Qrevo Master identifies up to 62 types of obstacles, whilst the S8 MaxV Ultra extends this figure to 73. In practice, this can translate into more precise avoidance of small or uncommon objects.
Both recognise pets and allow remote access to the camera from the mobile application. The night vision LED facilitates navigation in low light conditions. Neither incorporates specific curtain detection. Both use the RR Mason 11.0 algorithm and the SmartPlan 1.0 function to optimise cleaning routes according to room and floor type.
Autonomy and Battery
With 5,200 mAh capacity, both robots offer 180 minutes of autonomy, sufficient to cover large homes in a single session. This figure allows cleaning approximately between 250 and 300 square metres depending on the selected cleaning mode and the complexity of the environment.
In practice, this autonomy is more than sufficient for most homes, even those with complex layouts or multiple floors. Intelligent battery management allows the robot to calculate whether it needs to recharge before completing the cleaning.
Smart Functions
Both models can overcome obstacles up to 20 mm in height, which allows them to navigate thick carpets, door profiles or small level changes without getting stuck.
Both incorporate their own voice assistant, in addition to compatibility with Alexa and Google Home. This allows controlling the robot through voice commands without needing to open the mobile application.
Multifunction Cleaning Base
The multifunction bases of both robots include auto-emptying of the dust bin, mop washing with hot water and drying with hot air. This configuration guarantees minimal maintenance and effective mopping.
The dust bag capacity differs slightly: 2.7 litres on the Qrevo Master compared to 2.5 litres on the S8 MaxV Ultra. A minor difference that in practice barely affects the frequency of bag changes.
The water tanks are identical: 4 litres for clean water and 3.5 litres for dirty water. These capacities allow several mopping sessions without needing to manually refill or empty.
As already mentioned, the Qrevo Master stands out for its tray self-cleaning, whilst the S8 MaxV Ultra incorporates a detergent tank. Neither includes UV disinfection nor connection to plumbing, although they don't offer an optional kit for this function either.
Dimensions
The robots have exactly the same measurements: 353 mm diameter and 103 mm height. This contained height allows both to slide under low furniture, beds or sofas without problems.
The bases, however, present different configurations. The Qrevo Master measures 340 mm wide, 521 mm high and 487 mm deep. The S8 MaxV Ultra has 409 mm wide, 470 mm high and 419 mm deep. The Qrevo Master is narrower but taller and deeper, whilst the S8 MaxV Ultra is wider but less tall and deep. It's advisable to measure the available space before deciding, especially if you're planning to place the base under furniture or in a specific gap.
Real-world experience
For large homes, both robots offer sufficient autonomy and tank capacity. The difference will be in the type of mopping you prefer: rotary on the Qrevo Master or vibrating with mini side mop on the S8 MaxV Ultra.
If you live with pets, the DuoDivide double brush present on both models significantly reduces hair tangles. The 10,000 Pascals power guarantees deep vacuuming even on carpets where hair accumulates.
The S8 MaxV Ultra may be more convenient if you have medium or high pile carpets, thanks to its 20 mm mop lift. The Qrevo Master, with its 10 mm, works well with thin carpets but may wet them slightly if they are thicker.
Regarding maintenance, the Qrevo Master requires less intervention thanks to tray self-cleaning. The S8 MaxV Ultra compensates with the detergent tank that automatically dispenses, improving mopping results without needing to manually add product at each mop wash.
Conclusion: Which to choose?
Choose the Roborock Qrevo Master if... you prefer a rotating mop system, value tray self-cleaning to reduce maintenance and need a narrower base. It's ideal for homes with thin carpets or hard floors where rotary mopping offers good results. The larger dust bag capacity can also be a point in favour if you have pets that shed a lot of hair.
Choose the Roborock S8 MaxV Ultra if... you're looking for the highest mop lift on the market (20 mm) to coexist better with thick carpets, want automatic detergent dispensing and prefer broader obstacle recognition (73 types). The mini side mop improves edge mopping, and AI stain recognition guarantees superior results in especially dirty areas. If you have width space but height limitation, its base dimensions may fit better.
