Introduction
We're looking at three high-end robots launched in 2025 that represent the best from each manufacturer: the Dreame L40s Pro Ultra, the Roborock Qrevo S5V and the Xiaomi Robot Vacuum 5. All three feature a complete multifunction base, capable of auto-emptying the dust bin, washing the mops with hot water and drying them with hot air to prevent bad odours. These are devices designed for those seeking almost total autonomy and real mopping, not just passing a damp cloth over the floor.
The Dreame L40s Pro Ultra stands out for its technological approach with dual artificial intelligence camera and multiple sensors. The Roborock Qrevo S5V focuses on the reliability and simplicity characteristic of the world's leading brand. The Xiaomi Robot Vacuum 5 surprises with the highest suction power of the trio and a compact design with retractable LiDAR.
Power and Suction
The Xiaomi Robot Vacuum 5 leads in raw power with 20,000 Pa, followed very closely by the Dreame L40s Pro Ultra with 19,000 Pa. The Roborock Qrevo S5V stays at 12,000 Pa, a figure that may seem lower but in practice proves sufficient for most homes. The real difference is noticeable on thick carpets or when there's a lot of accumulated dirt.
Regarding brushes, each manufacturer opts for its own anti-tangle technology. The Dreame features its HyperStream dual brush system, specifically designed to prevent hair from wrapping around. The Roborock incorporates the DuoDivide, which pushes hair towards the centre to facilitate suction. The Xiaomi equips the TriCut 3.0, which combines bristles with blades to cut through tangles.
Here the Dreame makes a clear difference: it's the only one that lifts the main brush during mopping, which prevents dirtying the brush with dirty water and improves the robot's overall hygiene. It also lifts the side brush, something neither the Roborock nor the Xiaomi offer. All three models have an extendable side brush to better reach corners, except the Roborock which lacks this function.
Mopping
All three robots mop with two rotating mops, currently the most effective system on the market. All extend the mops to better reach edges, although the Dreame adds the Roboswing system: a lateral movement that allows the mop to get under furniture and overhangs.
Mop lifting varies slightly. The Xiaomi raises the mops up to 15 mm, the Dreame up to 10.5 mm and the Roborock up to 10 mm. This function is crucial for climbing onto thin carpets without wetting them or for moving around the house without dragging wet mops.
The Dreame L40s Pro Ultra incorporates functions that the other two don't have. It automatically removes the mops at the base when you only want to vacuum, preventing them from getting unnecessarily dirty. Additionally, it detects dirt both on the mops themselves and on the floor, adjusting mopping intensity or going back over areas that remain dirty. This represents a superior level of autonomy.
All three bases wash the mops with hot water and dry them with hot air, guaranteeing a hygienic result without bad odours. The Dreame adds third-generation self-cleaning to the washing tray, whilst the Xiaomi also cleans its tray but the Roborock doesn't include this function.
Navigation System
In basic navigation all three perform excellently. The Dreame and the Roborock feature traditional LiDAR turret, whilst the Xiaomi opts for retractable LiDAR that reduces the robot's total height to just 88 mm, allowing it to slip under furniture where the others can't fit.
The big difference lies in artificial intelligence. The Dreame L40s Pro Ultra features dual AI camera and recognises up to 180 different types of obstacles, including pets and curtains. It can remotely access the camera to monitor the home, has LED for night vision and detects stains on the floor to intensify mopping. The Xiaomi has front 3D laser sensor but no AI camera. The Roborock dispenses with camera and focuses on its SmartPlan system to plan efficient routes.
For homes with pets, the Dreame offers clear advantages: it recognises animals, avoids problematic areas and allows you to monitor what they're doing via the camera. The other two models avoid obstacles correctly but without that level of detail.
Autonomy and Battery
All three robots feature 5,200 mAh battery, but actual autonomy varies considerably. The Dreame reaches 220 minutes, the Roborock 180 and the Xiaomi stays at 140 minutes. These differences are explained by energy management and the suction power employed.
In large homes, the Dreame offers greater margin to complete cleaning in a single run. The Roborock performs well in flats up to 150-180 m². The Xiaomi, despite its lower autonomy, compensates with higher suction power, which can be interesting in small houses with carpets or lots of concentrated dirt.
Smart Functions
All three robots overcome obstacles up to 20 mm in height, although the Dreame specifies that it handles simple steps thanks to its brush and mop lifting system. In practice, this means passing without problems from wooden flooring to tiles or climbing medium-thickness carpets.
The Dreame L40s Pro Ultra incorporates its own voice assistant in addition to compatibility with Alexa and Google Home. The other two only work with external assistants. This function allows you to control the robot using more natural and specific voice commands, although its real usefulness depends on each user.
Multifunction Cleaning Base
All three bases fulfil the essential functions: they auto-empty dust, wash the mops with hot water and dry them with hot air. However, there are important differences in capacities and additional functions.
The Dreame has the largest dust bag at 3.2 litres, followed by the Roborock with 2.7 litres and the Xiaomi with 2.5 litres. In water tanks, the Dreame also leads with 4.5 litres of clean water and 4 of dirty. The Roborock features 4 and 3.5 litres respectively, whilst the Xiaomi equips 4 and 3.8 litres. These differences may seem small but affect how frequently you need to refill or empty the tanks.
Only the Dreame includes integrated detergent tank, which automatically dispenses product during mop washing. It's also the only one offering an optional kit for connection to water pipes, although you have to buy it separately and it doesn't come as standard.
Washing tray self-cleaning is present in the Dreame and the Xiaomi, but not in the Roborock. This means that with the Roborock you'll have to manually clean that area from time to time to prevent accumulation of dirt and bad odours.
Dimensions
The Xiaomi Robot Vacuum 5 is the lowest at 88 mm height thanks to its retractable LiDAR. This allows it to slip under sofas, beds and low furniture where the other two can't reach. The Roborock measures 96.5 mm and the Dreame reaches 103.8 mm. If you have lots of low furniture, this difference can be decisive.
In diameter they're practically equal: 350 mm for the Dreame and the Xiaomi, 353 mm for the Roborock. These are standard dimensions that allow good manoeuvrability in tight spaces.
The bases also vary in size. The Dreame's is the tallest at 590.5 mm, followed by the Xiaomi at 572 mm and the Roborock at 521 mm. In width, the Xiaomi needs 360 mm whilst Dreame and Roborock make do with 340 mm. It's worth measuring the space where you're going to place the base before deciding.
Real-World Experience
For large houses over 150 m², the Dreame L40s Pro Ultra offers the best combination: greater autonomy, larger tanks and smart functions that reduce supervision. Its ability to detect dirt and adjust mopping automatically proves especially useful when you can't keep an eye on the robot.
If you have pets, the Dreame stands out again for its specific animal recognition and dual anti-tangle brush system. The possibility of accessing the camera to see what your dog or cat is doing whilst cleaning adds an interesting bonus.
The Xiaomi Robot Vacuum 5 shines in flats with lots of low furniture thanks to its 88 mm height. Its 20,000 Pa power makes it the best option for thick carpets or houses where lots of dirt accumulates. The more limited autonomy isn't a problem in homes up to 100 m².
The Roborock Qrevo S5V focuses on reliability and simplicity. It's the robot for those seeking a device that works well without technical complications. Roborock's app is a benchmark in the sector and the brand has established after-sales service. Although it lacks some of the Dreame's advanced functions, it performs perfectly in the essentials.
Conclusion: Which to Choose?
