Introduction
The Dreame L10s Ultra Gen 2 and the Roborock Qrevo S Pro represent two distinct approaches within the high-end range of robot vacuum cleaners with multifunctional base stations. The Dreame model arrived on the market in 2024, whilst the Qrevo S Pro was launched in April 2026. We're looking at two complete units that vacuum, mop, wash their own mops and dry them with hot air, designed for users seeking to maximise home maintenance automation.
Both options are designed for medium to large-sized homes, with the ability to overcome obstacles up to 20 mm and advanced laser navigation systems. The differences in suction power, battery life and some details of the mopping system mark the distance between one and the other.
Power and Suction
The most striking difference in this section is marked by suction power. The Roborock Qrevo S Pro reaches 18,500 Pa, almost double the 10,000 Pa of the Dreame L10s Ultra Gen 2. This advantage translates into greater capacity to lift ingrained dirt, especially on carpets or tile joints.
As for the brushing system, both models feature a conventional bristle main brush, without elevation during mopping. Neither incorporates anti-tangle technology in the central brush, something to bear in mind if you live with long-haired pets.
The side brush marks an important difference: the Roborock Qrevo S Pro includes anti-tangle technology in its side brush, whilst the Dreame L10s Ultra Gen 2 does not. This can facilitate maintenance and reduce the frequency with which you need to untangle hair. Neither has an extendable or liftable side brush.
Mopping
Both robots mop with a dual rotating mop system, but here they begin to differ in details that affect the final result. The Dreame L10s Ultra Gen 2 incorporates mop extension with the Roboswing system, a movement that allows the robot to get the mops under overhangs and furniture, improving edge coverage. The Roborock Qrevo S Pro does not extend its mops.
Mop lifting is practically identical: 10.5 mm on the Dreame compared to 10 mm on the Roborock. Sufficient to avoid wetting low-pile rugs during mopping. Neither automatically removes the mops at the base when you only want to vacuum, nor detects dirt on the floor for automatic re-mopping.
Where there is a notable difference is in mop washing. The Roborock Qrevo S Pro washes the mops with hot water, which helps to better eliminate grease and adhered residue. The Dreame L10s Ultra Gen 2 washes them with cold water. Both dry the mops with hot air, preventing bad odours and bacterial growth.
The Dreame adds a detergent tank in the base, something the Roborock does not include. This allows the robot to dispense cleaning product during mop washing, improving system hygiene without the need to manually add detergent.
Navigation System
Both robots use a 3D LiDAR turret to map and navigate with precision, guaranteeing orderly and efficient routes. Both include obstacle avoidance, although neither features a front camera with artificial intelligence.
The advantage of the Dreame L10s Ultra Gen 2 lies in its front 3D laser sensor, which improves detection of small or low objects. Additionally, it incorporates specific pet recognition, useful for identifying and avoiding areas where animals or their accessories are located. The Roborock Qrevo S Pro does not have either of these two functions.
Neither offers remote camera access nor night vision LED. Regarding intelligent cleaning, the Dreame uses its CleanGenius system and the Roborock opts for SmartPlan 2.0, although neither detects stains with AI for automatic re-cleaning.
Battery Life and Battery
Both models feature a 5,200 mAh battery, but performance differs considerably. The Dreame L10s Ultra Gen 2 achieves 240 minutes of battery life, compared to the 180 minutes of the Roborock Qrevo S Pro. This one-hour difference can be decisive in large homes or when performing complete cleans with simultaneous vacuuming and mopping.
The Roborock's greater suction power consumes more energy, which partly explains this lower battery life. In practice, the Dreame can complete larger surfaces without needing to recharge, whilst the Roborock will need to interrupt cleaning in very large spaces.
Smart Functions
Both robots can overcome obstacles up to 20 mm, sufficient to pass over thick cables, mats or small uneven surfaces. Neither incorporates a robotic arm nor its own voice assistant, although both are compatible with Alexa and Google Home for external voice control.
Multifunctional Cleaning Base
Both bases are complete multifunctional units: they auto-empty the robot's dust container, wash the mops and dry them with hot air. Neither includes self-cleaning of the washing tray, UV disinfection nor automatic mop changing.
The dust bag capacity is larger in the Dreame L10s Ultra Gen 2, with 3.2 litres compared to the Roborock Qrevo S Pro's 2.7 litres. This translates into less frequent bag changes. The water tanks also favour the Dreame: 4.5 litres of clean water and 4 litres of dirty water, compared to 4 and 3.5 litres respectively in the Roborock.
The Dreame also offers an optional kit to connect the base to water pipes, avoiding manually refilling and emptying tanks. The Roborock does not contemplate this possibility even as an accessory.
Dimensions
The Roborock Qrevo S Pro robot is slightly more compact in height: 96.5 mm compared to the 97 mm of the Dreame L10s Ultra Gen 2. A minimal difference that does not significantly affect its ability to slip under furniture. The diameter is practically identical: 350 mm on the Dreame and 353 mm on the Roborock.
The bases have the same width (340 mm), but differ in height and depth. The Dreame base measures 590.5 mm in height and 456.7 mm in depth, whilst the Roborock is lower (519 mm) but deeper (487 mm). It's advisable to measure the space where you plan to position the base before deciding.
The robot's internal tanks are similar: 300 ml of dust in the Dreame compared to 330 ml in the Roborock, and 80 ml of water in both cases.
Real-World User Experience
For large homes, the Dreame L10s Ultra Gen 2 offers clear advantages thanks to its 240 minutes of battery life and larger water tanks in the base. You'll be able to complete extensive cleans without interruptions and space out base maintenance more. The mop extension with Roboswing also helps to better cover edges and corners.
If you have pets, the Roborock Qrevo S Pro stands out for its 18,500 Pa suction power and its anti-tangle side brush, reducing the time spent untangling hair. The Dreame compensates with specific pet recognition and front 3D laser sensor, useful for avoiding toys or feeding bowls.
The Roborock's hot water mop washing is a real advantage for eliminating grease and adhered residue, although the Dreame counters with its integrated detergent tank. Both dry the mops with hot air, guaranteeing hygiene.
The possibility of connecting the Dreame base to plumbing via an optional kit is interesting if you're seeking total automation, although it requires an additional investment and some installation.
Conclusion: Which to Choose?
Choose the Dreame L10s Ultra Gen 2 if... you live in a large house and value the extended battery life of 240 minutes. Also if you prefer larger tanks in the base to space out maintenance, or if the mop extension with Roboswing is useful for improving edge cleaning. The integrated detergent tank and the option of a plumbing connection kit are points in favour if you're seeking maximum convenience. Pet recognition and front 3D laser sensor add precision in navigation.
Choose the Roborock Qrevo S Pro if... suction power is a priority for you. Its 18,500 Pa makes a difference on carpets and ingrained dirt. The anti-tangle side brush facilitates maintenance if you live with pets, and hot water mop washing improves mopping hygiene. If your home doesn't exceed 150-180 m², the lower battery life won't be a problem. The lower base can be an advantage if available space is limited in height.
