Introduction
Choosing between the Dreame L50s Pro Ultra, the Roborock Qrevo S Pro and the Roborock S8 MaxV Ultra requires understanding what type of features each user is looking for. The Dreame model arrives in 2026 with a clear commitment to power and advanced recognition technology. The Qrevo S Pro, also from 2026, is presented as a more balanced alternative within the Roborock range. The S8 MaxV Ultra, launched in 2024, has already proven to be a benchmark in intelligent navigation and mopping versatility.
We're talking about three units with complete multifunction bases, designed for users looking to automate home cleaning to the maximum. The technical differences between them define distinct usage profiles, from homes with pets to spaces where suction power or obstacle recognition are determining factors.
Power and Suction
The difference in suction power is striking. The Dreame L50s Pro Ultra practically triples the force of the S8 MaxV Ultra with its 30,000 Pa, and clearly exceeds the Qrevo S Pro's 18,500 Pa. This translates into real capacity to extract embedded dirt from carpets or drag heavy particles without needing repeated passes.
The main brush system also makes a difference. Dreame and S8 MaxV have dual brushes, a design that reduces hair tangles and improves efficiency in homes with pets. The Qrevo S Pro uses a single brush, sufficient for most situations but less effective when there's a lot of long hair.
Dreame and S8 MaxV lift the main brush during mopping, preventing it from getting wet and reducing the risk of dispersing wet dirt. The Qrevo S Pro doesn't include this function. As for the side brush, the Dreame is the only one that lifts it during mopping, which prevents it from dragging dirty water over already clean areas. Dreame and S8 MaxV have an extendable side brush to improve corner cleaning, a function absent on the Qrevo S Pro.
The anti-tangle side brush appears on Dreame and Qrevo S Pro, but not on the S8 MaxV Ultra. For homes with long-haired pets, it's worth considering this feature alongside the type of main brush.
Mopping
Dreame and Qrevo S Pro use two rotating mops, a system that offers good results on hard floors and allows constant pressure to be applied. The S8 MaxV Ultra uses a vibrating mop, a different technology that is also effective although with different mechanical behaviour.
Mop extension for edges varies. The Dreame incorporates the Roboswing system, which performs a specific movement to get the mop under furniture and ledges. The S8 MaxV has a mini side mop that extends the mopping area. The Qrevo S Pro doesn't have any type of extension.
In mop lift, the S8 MaxV reaches 20 mm, sufficient to pass over medium-thickness carpets without wetting them. The Dreame reaches 10.5 mm and the Qrevo S Pro 10 mm. The difference can be particularly noticeable in homes with thick carpets or high doormats.
The Dreame L50s Pro Ultra automatically removes the mops at the base when it only needs to vacuum, a function that the other two models don't offer. This allows alternating tasks without manual intervention. Dirt detection on mops and floor is present on Dreame and S8 MaxV, which activates automatic re-mopping in dirtier areas. The Qrevo S Pro lacks this capability.
All three models wash the mops with hot water at the base and dry them with hot air, guaranteeing hygiene and preventing bad odours. This aspect is common and makes the difference compared to bases that only use water or cold air.
Navigation System
The Dreame L50s Pro Ultra and the S8 MaxV Ultra integrate dual AI camera, front 3D laser sensor, night vision LED and remote camera access. The Qrevo S Pro doesn't include any of these functions. In practice, this means that Dreame and S8 MaxV can identify objects precisely even in low-light conditions, send live images to the mobile and avoid complex obstacles with greater reliability.
The Dreame recognises 220 types of obstacles, the S8 MaxV 73. The Qrevo S Pro doesn't specify this figure, but lacking an AI camera, its identification capacity is lower. Pet recognition is present on Dreame and S8 MaxV, useful for avoiding getting too close to feeding bowls or animal resting areas. The Dreame adds curtain detection, avoiding tangles.
All three use a LiDAR turret to map the home and avoid basic obstacles, but the differences in AI and additional sensors affect performance in complex or changing environments.
Autonomy and Battery
All three units have a 5,200 mAh battery. The Qrevo S Pro and the S8 MaxV Ultra offer 180 minutes of autonomy. The Dreame doesn't provide a specific duration figure, although with the same battery capacity similar figures can be expected. Real autonomy will depend on the mode of use, the power selected and the type of floor.
Smart Functions
The Dreame L50s Pro Ultra overcomes simple steps without specifying exact height. The Qrevo S Pro and the S8 MaxV reach 20 mm, sufficient to negotiate most transitions between rooms or small level changes. This capability is useful in homes with irregular floor distribution.
The built-in voice assistant appears on Dreame and S8 MaxV Ultra, allowing direct control without going through Alexa or Google Home. All three models are compatible with external assistants.
Multifunction Cleaning Base
All three bases automatically empty the dust container, wash the mops with hot water and dry them with hot air. The Dreame incorporates third-generation tray self-cleaning, a system that keeps the area where the mops are washed clean without manual intervention. Neither Qrevo S Pro nor S8 MaxV include this function.
The detergent tank is present on Dreame and S8 MaxV, but not on the Qrevo S Pro. This allows product to be dispensed during mop washing, improving mopping hygiene. The Dreame also offers an optional plumbing connection kit, which is purchased separately and facilitates automatic water filling and emptying.
In terms of capacities, the Dreame's dust bag reaches 3.2 litres, compared to 2.7 litres for the Qrevo S Pro and 2.5 litres for the S8 MaxV. The clean water tank is 4.5 litres on the Dreame, 4 litres on Qrevo S Pro and S8 MaxV. Dirty water is stored in 4 litres on the Dreame and 3.5 litres on the other two. These differences influence maintenance frequency, especially in large homes.
Dimensions
The Qrevo S Pro is the lowest at 96.5 mm in height, making access under furniture easier. The Dreame measures 103.8 mm and the S8 MaxV 103 mm. Those few millimetres can make the difference with low sofas or beds. The diameter varies slightly: 350 mm on the Dreame, 353 mm on the two Roborocks.
The bases also differ. The Dreame measures 340 mm wide, 590 mm high and 457 mm deep. The Qrevo S Pro is 340 mm wide, 519 mm high and 487 mm deep. The S8 MaxV reaches 409 mm wide, 470 mm high and 419 mm deep. These measurements determine where the base can be located without taking up too much visible space.
Real-world experience
The Dreame L50s Pro Ultra stands out in large homes with pets, thanks to its 30,000 Pa power, dual main brush, anti-tangle and liftable side brush, and advanced detection of 220 obstacles. Automatic mop removal and tray self-cleaning reduce maintenance. The 3.2-litre bag and large water tanks allow long cycles without intervention.
The Qrevo S Pro is better suited to medium-sized homes without pets, where the 18,500 Pa power is sufficient and AI camera or mop extension aren't needed. Its reduced height makes cleaning under low furniture easier. The absence of a detergent tank and tray self-cleaning means slightly more manual maintenance.
The S8 MaxV Ultra suits users who value the 20 mm mop lift for thick carpets, dirt detection and remote camera access. Its dual main brush and mini side mop offer versatility, although the 10,000 Pa power may fall short on very dense carpets or embedded dirt.
Conclusion: Which to choose?
Choose the Dreame L50s Pro Ultra if you're looking for maximum suction power, more complete obstacle recognition, tray self-cleaning, automatic mop removal and larger capacity tanks. Ideal for large homes with pets, demanding carpets and users who prioritise total autonomy with minimum maintenance.
Choose the Roborock Qrevo S Pro if you need a balanced unit without AI camera, with reduced height to pass under low furniture, and don't require advanced functions such as mop extension or dirt detection. Suitable for medium-sized homes without pets, where the relationship between features and maintenance is more straightforward.
Choose the Roborock S8 MaxV Ultra if you value the 20 mm mop lift for thick carpets, remote camera access, dirt detection on floor and mops, and prefer already established technology from 2024. Recommended for users looking for mopping versatility and intelligent navigation without needing the Dreame's extreme power.
