Introduction
The Dreame Aqua10 Ultra Track Complete and the Roborock Saros 20 Sonic represent two high-end propositions launched just a few months apart. The former arrived on the market in 2025, whilst the Roborock model was introduced in 2026. We're looking at equipment designed for users seeking total automation in home cleaning, with complete multifunction bases and advanced navigation technology.
Dreame opts for a mopping system with a 180 mm wide roller that promises deep cleaning, whilst Roborock maintains its philosophy of sonic vibrating mops that have demonstrated good results in previous generations. The difference in height between models may prove decisive for those who need the robot to access beneath low furniture.
Power and Suction
The most evident difference in this section is suction power. The Roborock Saros 20 Sonic reaches 36,000 Pa, a figure notably higher than the 25,000 Pa of the Dreame Aqua10 Ultra Track Complete. This translates into greater capacity to extract ingrained dirt from carpets or vacuum heavier particles.
Regarding the brushing system, each manufacturer opts for its distinctive technology. The Dreame unit integrates the Doble Cepillo HyperStream, specifically designed to reduce hair tangles thanks to its configuration of two brushes anchored at one end. The Roborock model incorporates the DuoDivide Antienredos system, which pushes hairs towards the central gap to facilitate suction and minimise tangles.
Both robots lift the main brush during mopping and feature an extendable side brush to improve cleaning in corners. Both can also lift the side brush when mopping, preventing it from interfering with the mops. This function proves especially useful for maintaining mopping effectiveness without compromising suction capability at the edges.
Mopping
Here we find completely different philosophies. The Dreame Aqua10 Ultra Track Complete uses a 180 mm wide roller that rotates whilst mopping, covering more surface area with each pass. The Roborock Saros 20 Sonic maintains the sonic vibrating mop system, which generates high-frequency movements to remove adhered stains.
Both models extend their mopping systems to better reach edges. Mop lift differs slightly: the Dreame can lift them between 7 and 17 mm, whilst the Roborock reaches between 8 and 18 mm. That extra millimetre can make the difference when traversing medium-pile carpets.
The Dreame mops the floor with hot water at 45°C, a temperature that helps dissolve grease and stains better. The Roborock uses warm water without specifying exact degrees. An important difference: the Roborock Saros 20 Sonic can automatically remove the mops at the base when you only need to vacuum, whilst the Dreame requires doing this manually.
Both detect dirt on both the mops and the floor, adapting cleaning as necessary. This function allows particularly dirty areas to be gone over without manual intervention.
Navigation System
Both robots integrate retractable LiDAR to map the home with precision. They complement this technology with dual RGB camera in the case of the Dreame and dual camera without additional specification in the Roborock. Both include a front 3D laser sensor to detect obstacles at floor level.
The Roborock Saros 20 Sonic recognises up to 300 different objects, 20 more than the Dreame. In practice, this difference may be noticeable in homes with many items on the floor or scattered toys. Both identify pets and curtains, adjusting their behaviour to avoid tangles or disturbing animals.
Remote camera access is available on both units, allowing you to monitor the home from the app. Both incorporate LEDs for night vision, facilitating navigation in dark spaces without relying solely on LiDAR.
The Dreame uses the CleanGenius system with AI Sage 15.0 Octa-core processor, whilst the Roborock opts for SmartPlan 3.0 without detailing the specific processor. Both recognise stains using artificial intelligence and adapt cleaning according to detected needs.
Autonomy and Battery
Battery capacity is identical: 6,400 mAh in both models. This figure guarantees sufficient autonomy for large homes, although neither manufacturer specifies exact minutes of operation nor complete charging time.
With this capacity, they can typically cover large surfaces in a single session, returning to the base only to wash the mops during mopping or upon completing cleaning.
Smart Functions
The Dreame Aqua10 Ultra Track Complete overcomes single steps of up to 35 mm, whilst the Roborock Saros 20 Sonic reaches 40 mm. Those additional 5 mm can prove decisive in homes with high thresholds between rooms or small changes in floor level.
Both robots integrate their own voice assistant, allowing commands to be given directly without needing to use the mobile. They're also compatible with external assistants such as Alexa or Google Home to integrate them into existing home automation ecosystems.
Multifunction Cleaning Base
Both bases auto-empty the robot's dust container, wash the mops with hot water and dry them. The Dreame specifies that it dries at 50°C, whilst the Roborock indicates hot air without specifying temperature. Drying with hot air speeds up the process and reduces the risk of bad odours.
An important difference: the Roborock Saros 20 Sonic includes self-cleaning of the washing tray with hot water, keeping the base itself hygienic without manual intervention. The Dreame doesn't offer this function. In exchange, the Dreame model integrates UV disinfection to eliminate bacteria, something the Roborock doesn't incorporate.
The Dreame has a dual detergent tank, allowing different products to be used according to floor type or dirt. The Roborock has a single tank. This versatility can be utilised in homes with different types of flooring that require specific treatments.
The Dreame's dust bag has 3.2 litres capacity versus the Roborock's 2.5 litres. Those additional 700 ml mean fewer bag changes, especially relevant in houses with pets or heavy traffic. The clean water tank is the same in both: 4 litres. The dirty water tank reaches 3.5 litres in the Dreame and 3 litres in the Roborock.
The Dreame offers a plumbing connection kit that's purchased separately, allowing automation of water filling and emptying. The Roborock doesn't have this option. It's worth bearing in mind that this kit is an additional accessory, not included as standard.
Dimensions
Height marks a notable difference. The Roborock Saros 20 Sonic measures 79.8 mm, which allows it to access beneath furniture and low beds more easily. The Dreame Aqua10 Ultra Track Complete reaches 97.5 mm, almost 18 mm more. For homes with low sofas or furniture with little separation from the floor, this difference can determine which areas remain accessible.
Diameter is practically identical: 350 mm in the Dreame versus 353 mm in the Roborock. Those 3 mm don't represent a practical difference in manoeuvrability.
The bases also present similar dimensions. The Dreame measures 420 mm wide by 500 mm high and 440 mm deep. The Roborock has 409 mm width, 470 mm height and the same 440 mm depth. The Dreame's base is slightly taller, but both require considerable space.
Real-World Usage Experience
For large homes, the 6,400 mAh battery in both models guarantees sufficient autonomy. The Dreame's greater dust bag capacity reduces maintenance frequency, something to consider in houses with large surface areas or several occupants.
In homes with pets, the 36,000 Pa power of the Roborock Saros 20 Sonic offers an advantage for vacuuming hair embedded in carpets. Its DuoDivide system also helps minimise tangles. The Dreame, with its 25,000 Pa and Doble Cepillo HyperStream, remains effective although with less brute force.
The Roborock's height proves decisive if you have low furniture. At 79.8 mm it can access spaces that the Dreame, at 97.5 mm, cannot reach. This can mean the difference between cleaning completely under the bed or leaving areas uncovered.
The Roborock's automatic mop removal simplifies use when you only want to vacuum without mopping. With the Dreame you need to remove them manually, an additional step that can prove annoying if you frequently alternate between cleaning modes.
The Dreame's dual detergent tank provides flexibility to use specific products according to room or floor type. If you have parquet in some areas and tiles in others, you can optimise mopping without manually changing the product.
