Introduction
The Dreame Matrix10 Ultra, the Roborock Saros 20 Sonic and the Dreame X50 Ultra Blanca represent three high-end proposals with complete multifunction base stations. The two Dreame models arrived in 2025, whilst the Roborock Saros 20 Sonic was launched in March 2026. All three units integrate advanced navigation systems with retractable LiDAR, dual cameras and front 3D laser sensors, as well as base stations that wash and dry the mops automatically.
Although they share many smart functions, there are important differences in suction power, tank capacity, brush design and specific base station features. The Matrix10 Ultra stands out for its automatic mop changing system with three pairs included, whilst the Saros 20 Sonic achieves the highest suction power in the group. The X50 Ultra Blanca incorporates UV disinfection in the base station, something the other two do not have.
Power and Suction
The most evident difference in this section is marked by the Roborock Saros 20 Sonic with its 36,000 Pa of suction power, widely surpassing the 30,000 Pa of the Dreame Matrix10 Ultra and leaving behind the 20,000 Pa of the X50 Ultra Blanca. This advantage is especially useful on thick carpets or homes with pets that shed a lot of hair.
The main brush design also varies. The Saros 20 Sonic features Roborock's DuoDivide anti-tangle system, which pushes hairs towards the central gap to facilitate direct suction without them wrapping around the bristles. Both Dreame models incorporate the dual HyperStream brush, with two brushes anchored at one end that minimise tangles thanks to their floating configuration.
All three robots lift the main brush during mopping to prevent it from getting wet and have an extendable side brush that improves cleaning in corners. This side brush also lifts automatically when mopping and features anti-tangle technology in all three cases, which reduces manual maintenance.
Mopping
The mopping system clearly distinguishes two philosophies. The Matrix10 Ultra and the X50 Ultra Blanca use two rotating mops that spin on the floor, whilst the Roborock Saros 20 Sonic employs a sonic vibrating mop that scrubs through high-frequency vibration. Rotating mops usually cover more surface area in one pass, but sonic vibration can be more effective on stubborn stains.
All three models extend the mops to better reach edges. The Dreame models add the Roboswing system, which performs a lateral movement of the chassis to introduce the mop under furniture or overhangs. Mop lifting reaches 10.5 mm in both Dreame models, whilst the Saros 20 Sonic offers a variable range of 8 to 18 mm that allows better adaptation to carpets of different thicknesses.
The water temperature for mopping the floor marks another important difference. The Matrix10 Ultra mops with hot water, the Saros 20 Sonic with warm water and the X50 Ultra Blanca with cold water. Hot water helps to better dissolve grease and difficult stains, something worth considering in kitchens or high-traffic areas.
All three robots detect dirt on the mops and on the floor to adjust mopping intensity, and all can automatically remove the mops at the base station when only vacuuming is needed. The Matrix10 Ultra also incorporates an exclusive automatic mop changing system with three pairs included, which allows longer mopping sessions without manual intervention.
Navigation System
Navigation is based on retractable LiDAR in all three units, complemented with dual RGB cameras and front 3D laser sensor. This combination allows precise mapping and real-time obstacle detection.
The number of recognised objects varies notably. The Roborock Saros 20 Sonic identifies up to 300 different obstacles, the Dreame Matrix10 Ultra recognises 240 and the X50 Ultra Blanca reaches 200. In practice, this translates into greater capacity to distinguish small or unusual objects and avoid them without getting stuck.
All three models recognise pets, detect curtains to avoid tangling, incorporate LED for night vision and allow remote access to the camera from the mobile. The Matrix10 Ultra operates with the 64-core AI Sage 15.0 algorithm, whilst the X50 Ultra Blanca features the 16-core version 13.0. The Saros 20 Sonic processor is not specified in the available data.
Autonomy and Battery
All three robots are equipped with 6,400 mAh batteries, but the declared autonomy differs. The Dreame Matrix10 Ultra reaches 260 minutes, the X50 Ultra Blanca achieves 180 minutes and this data is not available for the Roborock Saros 20 Sonic. The greater autonomy of the Matrix10 Ultra is advantageous in large homes where the entire surface needs to be completed without intermediate recharges.
Energy consumption also depends on the suction power used and the activated mopping mode, which partly explains the differences between models despite featuring the same battery capacity.
Smart Functions
All three units overcome simple steps without problem, although none incorporates a robotic arm to manipulate objects. All integrate their own voice assistant and are compatible with Alexa and Google Home, which facilitates control by voice commands without needing to open the mobile application.
AI-powered smart cleaning is present in all three cases. The Matrix10 Ultra and the X50 Ultra Blanca use Dreame's CleanGenius, whilst the Saros 20 Sonic implements Roborock's SmartPlan. Both systems automatically adjust suction power and mopping intensity according to floor type and detected dirt level.
Multifunction Cleaning Base Station
All three base stations perform auto-emptying of the dust container, washing and drying of mops. Washing is carried out with hot water in the Matrix10 Ultra and the Saros 20 Sonic, whilst the X50 Ultra Blanca washes with cold water. Drying uses hot air in all three models to speed up the process and prevent bad odours.
Self-cleaning of the washing tray operates with 3.5th generation hot water in the Matrix10 Ultra, with 3rd generation hot water in the X50 Ultra Blanca and with hot water in the Saros 20 Sonic without specifying generation. This function keeps the area where the mops are washed clean, preventing dirt accumulation.
The detergent tank is present in all three, but only the Matrix10 Ultra offers a triple system that allows using three different products according to floor type or task. The X50 Ultra Blanca incorporates UV disinfection in the base station, something the other two models do not have and which may be interesting for eliminating bacteria on the mops.
The dust bag capacity reaches 3.2 litres in both Dreame models, versus 2.5 litres in the Roborock. The clean water tanks measure 5.5 litres in the Matrix10 Ultra, 4.5 litres in the X50 Ultra Blanca and 4 litres in the Saros 20 Sonic. Dirty water is stored in 4 litres in the Dreame models and 3 litres in the Roborock. Larger tanks mean fewer manual refills, especially useful in large homes with lots of floor to mop.
The Matrix10 Ultra and the X50 Ultra Blanca offer a plumbing connection kit that is purchased separately, allowing automation of water filling and emptying. The Saros 20 Sonic does not have this option.
Dimensions
The Roborock Saros 20 Sonic measures 79.8 mm in height, which allows it to slip under low furniture more easily than the two Dreame models, which reach 89 mm. This difference of almost one centimetre can make the difference with sofas, beds or furniture with little clearance.
The diameter barely varies: 353 mm in the Saros 20 Sonic versus 350 mm in both Dreame models. As for the base station, the X50 Ultra Blanca is more compact in width (340 mm) compared to the 416 mm of the Matrix10 Ultra and the 409 mm of the Saros 20 Sonic. The base station height also differs: 470 mm in the Roborock, 590 mm in the Matrix10 Ultra and 590.5 mm in the X50 Ultra Blanca.
For small spaces where the base station must fit in a specific gap, it is advisable to measure carefully before deciding.
Real-world usage experience
The Roborock Saros 20 Sonic fits well in homes with thick carpets or pets that shed a lot of hair, thanks to its 36,000 Pa power and its DuoDivide brush. Its lower height allows it to access under more furniture, something practical in flats with low sofas or beds without tall legs. The ability to recognise up to 300 objects reduces jams in homes with many small obstacles.
The Dreame Matrix10 Ultra stands out in large homes where mopping is frequent. Its 260-minute autonomy, the automatic mop changing system with three pairs and the larger water tanks (5.5 litres of clean water) allow cleaning large surfaces without intervention. The triple detergent tank is useful if you combine different types of flooring that require specific products. Hot water for mopping improves results in kitchens or areas with grease.
The Dreame X50 Ultra Blanca sits at an intermediate point. Its 20,000 Pa power is sufficient for hard floors and thin carpets, although it may fall short on very thick carpets. UV disinfection in the base station adds a hygiene bonus for those seeking to eliminate bacteria from the mops. Its more compact base station width facilitates installation in tight spaces.
All three models automatically remove the mops at the base station when only vacuuming is needed, which simplifies daily use. Dirt detection adjusts cleaning intensity without needing to manually configure each zone, and remote access to the camera allows monitoring pets or checking cleaning status from anywhere.
