Introduction
Dreame presents two proposals within its Aqua 10 Ultra series for 2025: the Roller and the Track Complete. Both belong to the high-end range of robot vacuum cleaners with multifunction base, but incorporate completely different mopping systems. Whilst the Roller opts for a roller with 12N of pressure, the Track Complete integrates a wide roller with hot water technology. The Roborock Saros 20, launched in February 2026, arrives with the DuoDivide system and a different approach to navigation and design, competing directly in this premium segment.
These devices are designed for homes seeking total automation in vacuuming and mopping, especially useful in households with pets or mixed surfaces. The difference in mopping systems and the robot's height define distinct usage profiles worth analysing.
Power and Suction
Suction power varies considerably in this robot vacuum cleaner comparison. The Roborock Saros 20 leads with 36,000 Pa, followed by the Dreame Aqua 10 Ultra Roller with 30,000 Pa. The Track Complete remains at 25,000 Pa, a figure that is still competitive but noticeably lower. This difference may prove relevant on thick carpets or when there is significant dirt accumulation.
Regarding the main brush, both Dreame models feature a dual brush with anti-tangle technology, whilst the Saros 20 is equipped with the DuoDivide system, specifically designed to push hair towards the centre and prevent tangles. All three raise the main brush during mopping, a fundamental feature to avoid dirtying freshly mopped floors.
The side brush is extendable on all three models and also raises during mopping. All incorporate anti-tangle technology in this component, which facilitates maintenance and reduces manual intervention. In practice, this means less time spent untangling hair and more actual robot autonomy.
Mopping
Here we find the most marked differences. The Dreame Aqua 10 Ultra Roller uses a roller with 12N of pressure that mops with cold water. The Track Complete also employs a wide roller but adds hot water at 60°C for floor mopping, which improves the dissolution of grease and adhered dirt. The Roborock Saros 20 opts for two rotating mops with warm water, an intermediate approach.
Mop lifting also presents variations. The Roller reaches 14 mm with RoboSwing mode, the Track Complete between 7-17 mm, and the Saros 20 offers a range of 12-22 mm, the widest of the three. This capability proves critical for crossing carpets without wetting them or for overcoming small obstacles without dragging dirty mops.
Only the Roborock Saros 20 automatically removes the mops at the base when you only need to vacuum. Both Dreame models keep the mops installed, albeit raised. Dirt detection on both mops and floor is present on all three devices, allowing automatic re-mopping in dirtier areas.
Mop extension for edges is available on all, improving mopping in corners and skirting boards.
Navigation System
All three robot vacuum cleaners integrate retractable LiDAR, dual RGB cameras and front 3D laser sensor. The Dreame Aqua 10 Ultra Roller recognises 240 different obstacles, the Track Complete extends to 280, and the Roborock Saros 20 reaches 300. This recognition capability directly influences navigation precision and avoidance of small objects such as cables, toys or socks.
The Saros 20 uses Roborock's StarSight 2.0 system, whilst the Dreame models are equipped with AI Sage 15.0 CPU with CleanGenius. All three include LED for night vision, pet recognition, curtain detection and remote camera access from the mobile. In practice, this allows home surveillance when you're away.
Autonomy and Battery
Battery capacity is identical across all three models: 6,400 mAh. The Dreame Aqua 10 Ultra Roller specifies 160 minutes of autonomy, although the other two do not detail this figure. With this capacity, any of these robots can cover large homes without requiring intermediate recharges.
The maximum recommended surface area is not specified for any of them, but considering the Roller's autonomy and the shared battery capacity, all are prepared for large spaces.
Smart Functions
All three robots can overcome simple steps, facilitating transit between rooms with small level differences. All incorporate their own voice assistant in addition to compatibility with Alexa and Google Home, allowing voice control without depending exclusively on the app.
The robot's internal tanks show small differences. The Roborock Saros 20 has a 270 ml dust tank compared to the 220 ml of both Dreame models. However, the water tank is larger in the Dreame models: 160 ml against only 69 ml in the Saros 20. This may be particularly noticeable in long mopping sessions, where the Saros 20 will depend more on returns to base to refill water.
Multifunction Cleaning Base
All three bases include auto-emptying, mop washing and drying. The Dreame Aqua10 Ultra Track Complete dries the mops at 50°C and adds UV disinfection, features that the Roller does not specify clearly. The Roborock Saros 20 dries with hot air but does not include UV.
An important difference: only the Saros 20 incorporates self-cleaning of the washing tray with hot water at 60°C. Both Dreame models do not have this function, which implies periodic manual cleaning of the tray to prevent dirt accumulation.
The Dreame models offer dual detergent tank, useful for differentiating products according to floor type or dirt level. The Saros 20 includes a single tank. Dust bag capacity is greater in the Dreame models: 3.2 litres compared to 2.5 litres in the Roborock. Clean water tanks are identical (4 litres), but the dirty water tank is slightly larger in the Dreame models: 3.5 litres against 3 litres.
Both Dreame models offer an optional kit for plumbing connection, although it must be purchased separately. The Saros 20 does not contemplate this option.
Dimensions
The Roborock Saros 20 stands out for its reduced height: 79.8 mm. Both Dreame models measure 97.5 mm, almost 2 centimetres more. This difference proves decisive for passing under low furniture, sofas or beds with little clearance from the floor. The diameter is practically identical: 350 mm in the Dreame models and 353 mm in the Roborock.
The bases also present variations. The Dreame models measure 420 mm wide, 500 mm high and 440 mm deep. The Saros 20 is somewhat more compact in width (381 mm) and height (488 mm), but deeper (475 mm). It's advisable to measure the available space before deciding, especially if the base goes in a corner or cupboard.
Real-world usage experience
For large homes, all three devices are well dimensioned thanks to their 6,400 mAh battery. The Roborock Saros 20 provides an advantage with its greater suction power (36,000 Pa) and capacity to recognise more obstacles, which translates into faster and more efficient cleaning in large spaces.
If you live with pets, the anti-tangle systems of all three robots work well. The Saros 20's DuoDivide and the Dreame models' dual brush are specifically designed to minimise hair tangles. The greater dust bag capacity in the Dreame models (3.2 L) reduces replacement frequency.
The Track Complete's hot water mopping makes a difference in kitchens or areas with grease. The Roller with cold water maintains good performance in daily maintenance, whilst the Saros 20 with warm water positions itself in the middle ground. The Saros 20's tray self-cleaning reduces the manual maintenance that the Dreame models do require.
For homes with low furniture, the Saros 20 accesses spaces inaccessible to the other two thanks to its 79.8 mm height. If you have sofas or beds with little clearance from the floor, this may be decisive.
Conclusion: Which to choose?
Choose the Dreame Aqua 10 Ultra Roller if you're looking for a balance between power (30,000 Pa) and price within the high-end range. Its roller system with 12N of pressure works well in daily maintenance, and the specified 160 minutes of autonomy guarantee wide coverage. The dual RGB camera and 240 recognised obstacles offer reliable navigation. Ideal if you don't need hot water for mopping and prefer to invest less than in the Track Complete.
Choose the Dreame Aqua10 Ultra Track Complete if you prioritise intensive mopping with hot water at 60°C and mop drying at 50°C with UV disinfection. Although suction power is lower (25,000 Pa), it remains sufficient for most homes. It recognises 280 obstacles, more than the Roller, and the hot water system proves especially useful in kitchens or homes with young children where hygiene is a priority.
Choose the Roborock Saros 20 if you need the highest available suction power (36,000 Pa) and a robot that passes under very low furniture thanks to its 79.8 mm height. Automatic mop removal for vacuuming without dragging them and tray self-cleaning with hot water reduce maintenance. It recognises up to 300 obstacles, the highest figure, and its 270 ml dust tank surpasses the Dreame models. Perfect for those who value the Roborock brand and seek a low and powerful robot, although the internal water tank is more limited.
