Introduction
This comparison brings together three high-end robots with different approaches: the Dreame Aqua 10 Ultra Roller, the Roborock Qrevo Edge 2 and the Roborock Saros 10R. All three models integrate a complete multifunction base, AI navigation and advanced mopping systems, although each one excels in different aspects.
The Dreame Aqua 10 Ultra Roller opts for a roller mopping system that exerts 12N of pressure, whilst the two Roborock models maintain the rotating mop system. The difference in height is significant: the Dreame measures 97.5 mm compared to the 79.8 mm of the Roborock models, which directly influences their ability to slip under furniture. In terms of raw power, the Dreame reaches 30,000 Pa, far exceeding its competitors.
Power and Suction
The Dreame robot vacuum dominates in suction power with 30,000 Pa, a figure that exceeds the Roborock Qrevo Edge 2 by 5,000 Pa and practically doubles the 18,500 Pa of the Saros 10R. This difference translates into greater capacity to extract ingrained dirt from carpets or vacuum heavy particles.
As for the main brush, the Dreame Aqua 10 Ultra Roller features the Doble Cepillo HyperStream Antienredos system, whilst the two Roborock models use the DuoDivide Antienredos. Both systems are designed to minimise hair tangles, although with different mechanics. All three robots raise the main brush during mopping, preventing it from getting unnecessarily wet.
The side brush is extendable on all three models to better reach corners. However, only the Dreame Aqua 10 Ultra Roller and the Roborock Saros 10R raise the side brush during mopping, whilst the Qrevo Edge 2 keeps the brush fixed. This can influence how the robot behaves when mopping near walls.
Mopping
Here we find the most notable difference between these three robots. The Dreame Aqua 10 Ultra Roller uses a roller that exerts 12N of constant pressure on the floor, a system that allows mopping with greater force and which is especially effective on stuck-on stains. The Roborock Qrevo Edge 2 features two rotating mops at 230 RPM with 8N of pressure, whilst the Saros 10R rotates at 200 RPM without specifying exact pressure.
All three models extend their mopping systems to reach the edges. Mop lift varies: the Dreame lifts up to 14 mm and also covers the roller to protect it, the Qrevo Edge 2 reaches 12 mm and the Saros 10R offers a range of 12 to 22 mm, the highest lift in the group.
The Dreame mops with cold water, whilst both Roborock models use warm water, which improves the dissolution of grease. A clear advantage of the Qrevo Edge 2 and the Saros 10R is that they automatically remove the mops at the base when you only need to vacuum, avoiding dragging them dry across the floor. The Dreame doesn't offer this function.
All three robots detect dirt both on the mops and on the floor, adjusting the mopping intensity as needed.
Navigation System
The Dreame Aqua 10 Ultra Roller and the Roborock Qrevo Edge 2 share 360° retractable LiDAR technology, whilst the Saros 10R uses the StarSight 2.0 system. All three integrate an AI camera: dual RGB on the Dreame, single camera on the Qrevo Edge 2 and dual on the Saros 10R. All include a front 3D laser sensor to avoid obstacles at ground level.
The Qrevo Edge 2 recognises up to 280 types of obstacles, followed by the Dreame with 240 and the Saros 10R with 108. In practice, this means that the Qrevo Edge 2 has greater capacity to identify specific objects and adapt its behaviour. All three recognise pets and allow remote access to the camera.
The Dreame Aqua 10 Ultra Roller and the Qrevo Edge 2 detect curtains, a useful function to prevent the robot from getting tangled. The Saros 10R doesn't include this capability. All have LED for night vision.
The Dreame's processor is the AI Sage 15.0 Octa-core, whilst the Saros 10R features the RR Mason 11.0. The Qrevo Edge 2 doesn't specify a processor. As for intelligent cleaning systems, the Dreame uses CleanGenius 3.0, the Qrevo Edge 2 SmartPlan 3.0 and the Saros 10R SmartPlan 2.0.
Autonomy and Battery
The Dreame Aqua 10 Ultra Roller and the Roborock Saros 10R share a 6,400 mAh battery, compared to the 5,200 mAh of the Qrevo Edge 2. However, the declared autonomy is 188 minutes for the Qrevo Edge 2, 180 minutes for the Saros 10R and 160 minutes for the Dreame. This indicates that the Qrevo Edge 2 optimises energy consumption better despite having lower battery capacity.
Smart Functions
The ability to overcome obstacles marks important differences. The Dreame Aqua 10 Ultra Roller can navigate single steps of up to 42 mm and double steps of 80 mm, figures far superior to the 20 mm of the Qrevo Edge 2 and the 30 mm single/40 mm double of the Saros 10R. This makes the Dreame the best option for homes with pronounced uneven surfaces or thick carpets.
All three robots include their own voice assistant and compatibility with external assistants such as Alexa or Google Home.
Multifunction Cleaning Base
All three models integrate auto-emptying of the dust bin, mop washing and drying. The Dreame washes the mops with hot water at 100°C, a higher temperature than the 80°C of the Roborock models. This difference can be useful for eliminating bacteria more effectively.
The Qrevo Edge 2 dries the mops with hot air at 55°C, the Saros 10R at 45°C, whilst the Dreame doesn't specify drying temperature. The Qrevo Edge 2 and the Saros 10R include tray self-cleaning 2.0, a function that doesn't appear on the Dreame.
The Dreame Aqua 10 Ultra Roller stands out with a dual detergent tank, allowing the use of different products depending on the type of floor. The Saros 10R has a single tank and the Qrevo Edge 2 doesn't integrate a detergent tank.
The dust bag capacity is greater on the Dreame with 3.2 litres, compared to 2.7 litres of the Qrevo Edge 2 and 2.5 litres of the Saros 10R. All three share a 4-litre clean water tank. The dirty water tank is 3.5 litres on the Dreame and the Qrevo Edge 2, and 3 litres on the Saros 10R.
Only the Dreame offers a plumbing connection kit, although it's purchased separately.
Dimensions
Height is where these robots differ most. The Dreame Aqua 10 Ultra Roller measures 97.5 mm, whilst the Roborock Qrevo Edge 2 and the Saros 10R remain at 79.8 mm. This difference of almost 18 mm can be decisive if you need the robot to pass under low furniture, sofas or beds with little clearance from the floor.
In diameter there's barely any variation: 350 mm on the Dreame, 352 mm on the Qrevo Edge 2 and 353 mm on the Saros 10R.
The bases also differ in size. The Dreame's measures 420 mm wide, 500 mm high and 440 mm deep. The Qrevo Edge 2 measures 340 mm wide, 521 mm high and 487 mm deep. The Saros 10R has 381 mm wide, 488 mm high and 475 mm deep. The Dreame's base is the widest but the least deep.
Real-world user experience
For large homes, the Roborock Qrevo Edge 2 offers the best autonomy with 188 minutes, although the Saros 10R and the Dreame also cover large surfaces without problems. The robot's dust bin is slightly larger on the Saros 10R with 270 ml, followed by the Qrevo Edge 2 with 240 ml and the Dreame with 220 ml.
If you have pets, all three models feature anti-tangle brushes and specific animal recognition. The 30,000 Pa power of the Dreame can make a difference on carpets with a lot of accumulated hair.
The Dreame's roller system is more effective on difficult stains thanks to the constant pressure of 12N and washing at 100°C. However, the Roborock's rotating mops offer greater versatility as they can be automatically removed when you only want to vacuum.
The Dreame's ability to overcome steps of up to 80 mm makes it the most capable option for homes with uneven surfaces, thick carpets or complicated transitions between rooms. The Qrevo Edge 2, with only 20 mm, may have difficulties in these scenarios.
If you're looking for a robot that passes under low furniture, the Roborock models with 79.8 mm height have a clear advantage over the 97.5 mm of the Dreame.
Conclusion: Which one to choose?
Choose the Dreame Aqua 10 Ultra Roller if: You need maximum suction power (30,000 Pa), you have thick carpets or significant uneven surfaces at home (overcomes up to 80 mm), you prefer a mopping system with roller and constant pressure, and you value having a dual detergent tank. Also if you're looking for the largest dust bag capacity (3.2 L) and you don't mind sacrificing some height to pass under furniture.
Choose the Roborock Qrevo Edge 2 if: You're looking for the greatest autonomy (188 minutes), you need the robot to recognise the maximum number of obstacles (280 types), you value the mops being automatically removed to vacuum without dragging them, and your home has low furniture under which you need a robot of only 79.8 mm height to pass. Ideal if you don't need an integrated detergent tank and prefer a compact model.
Choose the Roborock Saros 10R if: You want balance between power and autonomy (6,400 mAh, 180 minutes), you need good obstacle climbing capability (up to 40 mm on double steps), you value having a single detergent tank and tray self-cleaning 2.0, and you're looking for a low robot (79.8 mm) that also automatically removes the mops. Good intermediate option between the other two models in price and features.
