Introduction
This comparison analyses three mid-to-high-end robots launched between 2024 and 2025: the Dreame L10s Ultra Gen 2 and two Roborock models, the Qrevo S5V and the QV 35A. All three integrate a multifunction base that handles auto-emptying, mop washing and drying, placing them amongst the most comprehensive options on the market for those seeking genuine home maintenance automation.
The Dreame L10s Ultra Gen 2 represents Dreame's commitment to competing in advanced features at a more competitive price than premium rivals. The two Roborock models arrive in 2025 with the backing of the world's leading robot vacuum brand, albeit with slightly different specifications between them. These units are designed for homes requiring both powerful vacuuming and effective mopping without constant user intervention.
Power and Suction
The Roborock Qrevo S5V dominates this category with 12,000 Pa of suction power, substantially exceeding the Dreame L10s Ultra Gen 2's 10,000 Pa and leaving the QV 35A's 8,000 Pa behind. This difference can be particularly noticeable on medium or long-pile carpets, where the ability to extract embedded dirt creates real distinctions between models.
The brushing system shows different approaches. The Qrevo S5V features Roborock's DuoDivide anti-tangle brush, which pushes hair towards the central suction gap, significantly reducing tangles. Both the Dreame and QV 35A use a simple brush, more prone to accumulating long hair requiring periodic manual cleaning.
Regarding the side brush, both Roborock models incorporate an anti-tangle design, whilst the Dreame doesn't. None of the three models offers an extendable or liftable side brush during mopping. For homes with long-haired pets, the Qrevo S5V presents clear advantages in both the main and side brushes.
Mopping
All three robots employ a dual rotating mop system, but differences in edge extension are notable. The Dreame L10s Ultra Gen 2 combines mop extension with Roboswing movement, allowing the robot to make a swaying motion to push the mop under overhangs and low furniture. The Roborock Qrevo S5V extends the mops towards edges but without this additional movement. The QV 35A, however, doesn't extend the mops at all, leaving the final millimetres along skirting boards unmopped.
Mop lift reaches 10.5 mm on the Dreame and 10 mm on both Roborock models. Minimal differences that in practice function similarly to avoid wetting thin rugs as the robot passes.
Where the Dreame creates real distance is in mop drying. It uses hot air at 60°C, accelerating the process and reducing risks of bad odours or bacterial growth. The Roborock models dry with cold air, a slower method that can leave mops damp for longer. For homes with high ambient humidity, the Dreame's hot air drying proves more effective.
The Dreame also includes a detergent tank in the base, which dispenses product during mop washing. Neither the Qrevo S5V nor the QV 35A offer this option, limiting themselves to clean water use. None of the three allows automatic mop removal at the base for vacuum-only sessions, nor detects dirt on mops or floors to adjust cleaning.
Navigation System
All three models use a LiDAR turret to map the home and plan efficient routes. All feature obstacle avoidance, but none integrates an AI camera or LED for night vision.
The Dreame L10s Ultra Gen 2 distinguishes itself by incorporating a front 3D laser sensor and pet recognition. This allows it to identify animals in real time and adapt its behaviour, avoiding disturbing them or vacuuming potential accidents. The Roborock Qrevo S5V and QV 35A lack these functions.
Regarding artificial intelligence, the Dreame uses CleanGenius whilst the Roborock models employ SmartPlan. Proprietary systems from each brand to optimise routes and manage cleaning autonomously. None of the three detects specific stains via AI nor offers remote camera access, as they don't feature this component.
Battery Life and Battery
Battery capacity is identical across all three: 5,200 mAh. However, declared battery life varies significantly. The Dreame L10s Ultra Gen 2 achieves 240 minutes of continuous use, whilst the Roborock Qrevo S5V and QV 35A remain at 180 minutes.
This one-hour difference can prove decisive in large homes. The Dreame covers more area without needing to return to the base for mid-session recharging. In flats up to 120-150 m², any of the three completes cleaning without issues. For larger areas, the Dreame offers greater safety margin.
Smart Functions
All three robots overcome obstacles up to 20 mm in height, sufficient to navigate thick cables, short-pile rugs or small transitions between rooms. None features a robotic arm or built-in voice assistant, though all are compatible with Alexa and Google Home for control via external voice commands.
Multifunction Cleaning Base
All three bases perform dust bin auto-emptying, mop washing with cold water and drying. The main difference lies in drying temperature: hot air at 60°C in the Dreame, cold air in the Roborock models.
The Dreame L10s Ultra Gen 2 integrates a detergent tank, absent in both Roborock models. This allows mop washing with cleaning product, improving mopping hygiene. Additionally, the Dreame offers an optional plumbing connection kit, though it must be purchased separately and doesn't come factory-integrated.
Dust bag capacity reaches 3.2 litres in the Dreame versus 2.7 litres in the Roborock models. Greater capacity means fewer bag changes, especially useful in homes with pets or high dirt traffic. Clean and dirty water tanks also favour the Dreame: 4.5 and 4 litres respectively, compared to 4 and 3.5 litres in the Roborock models. Differences that in practice translate to greater autonomy between water refills.
None of the three bases includes self-cleaning of the washing tray, UV disinfection or direct plumbing connection. Neither do they allow automatic mop changing.
Dimensions
The Dreame's diameter is 350 mm, slightly smaller than the Roborock Qrevo S5V and QV 35A's 353 mm. A minimal difference that doesn't affect access under furniture. Height does vary: 97 mm on the Dreame versus 96.5 mm on the Roborock models. Half a millimetre that in practice makes no real difference when passing under beds or low sofas.
The bases present different dimensions. The Dreame measures 340 mm wide, 590.5 mm high and 456.7 mm deep. The Roborock models share measurements: 340 mm wide, 521 mm high and 487 mm deep. The Dreame's base is taller but less deep, occupying vertical space. The Roborock bases are lower but extend further forward. It's advisable to measure available space before deciding.
Real-world usage experience
For homes with pets, the Roborock Qrevo S5V offers the best balance: superior suction power, DuoDivide anti-tangle main brush and anti-tangle side brush too. It drastically reduces manual maintenance. The Dreame counters with pet recognition and greater battery life, useful in large houses where the robot must cover more area without interruptions.
In homes with young children or tendency for frequent spills, the Dreame's detergent tank adds real value by washing mops with cleaning product. Hot air drying also accelerates the process, leaving mops ready sooner for the next session.
The Dreame's mop extension system with Roboswing cleans better under furniture overhangs and radiators. The Qrevo S5V extends the mops but without this additional movement. The QV 35A, by not extending, leaves edges unmopped, an important limitation if seeking complete mopping to the last corner.
For small or medium flats (up to 100 m²), the Roborock QV 35A performs without issues despite its lower power and absence of mop extension. Its price is usually more competitive than the Qrevo S5V, making it interesting if budget is limited and advanced features aren't needed.
Conclusion: Which to choose?
Choose the Dreame L10s Ultra Gen 2 if you're seeking the longest possible battery life (240 minutes), need an integrated detergent tank, value hot air mop drying and want mop extension with Roboswing movement to clean under furniture. Also if you have pets and are interested in specific animal recognition. The larger dust bag capacity and water tanks reduce maintenance frequency. Ideal for large homes with pets and users who prioritise total autonomy.
Choose the Roborock Qrevo S5V if you need maximum suction power (12,000 Pa) and the best anti-tangle system on the market with DuoDivide brush and anti-tangle side brush. Perfect for homes with long-haired pets where hair accumulation is the main problem. Mop extension covers edges better than the QV 35A, though without the Dreame's additional movement. A balanced option for those who trust Roborock's reliability and need superior vacuuming power.
Choose the Roborock QV 35A if your home is medium-sized (up to 100 m²), you don't have long-haired pets and are seeking a more economical option within the Roborock range. The 8,000 Pa of suction is sufficient for hard floors and thin carpets. The absence of mop extension limits edge mopping, but if you prioritise vacuuming over mopping and value Roborock's reliability without needing all the Qrevo S5V's features, this model delivers without complications.
