Introduction
The Dreame Matrix10 Ultra, the Roborock Saros 10R and the Dreame X50 Ultra Blanca represent three high-end proposals launched in 2025 that aim to offer complete autonomous cleaning solutions. All three models integrate a multifunctional base with mop washing and drying, advanced navigation with artificial intelligence and mopping systems with rotating mops. However, each one presents technical particularities that orient them towards different user profiles.
The Matrix10 Ultra positions itself as the most powerful and complete model in this robot vacuum comparison, whilst the Saros 10R stands out for its compact design and Roborock's established reputation. The X50 Ultra Blanca offers an intermediate alternative within the Dreame ecosystem, with distinctive features that deserve attention.
Power and Suction
Suction power marks notable differences in this robot vacuum comparison. The Dreame Matrix10 Ultra leads with 30,000 Pa, a figure that places it in the sector's elite and which is especially useful for long-pile carpets or homes with pets. The Roborock Saros 10R remains at 18,500 Pa, sufficient for most domestic situations but notably lower. The X50 Ultra Blanca reaches 20,000 Pa, positioning itself at a reasonable middle ground.
Regarding the brushing system, we find different philosophies. Both Dreame models equip dual HyperStream anti-tangle brush, a design with two brushes anchored at one end that minimises hair tangles. The Roborock robot vacuum opts for its DuoDivide anti-tangle brush, which pushes hairs towards the central gap to facilitate direct suction. Both approaches work well, although Dreame's system tends to require less maintenance when living with long-haired pets.
All three robots lift the main brush during mopping and also incorporate an extendable and liftable side brush, features that improve both corner sweeping and mopping efficiency without dragging dry dirt.
Mopping
The mopping system is where significant differences appear that affect the final result. All three models use two rotating mops, but the Matrix10 Ultra and the X50 Ultra Blanca add the Roboswing system, that characteristic swinging movement that allows the mop to get under furniture and ledges more effectively. The Saros 10R doesn't include this function, although it compensates with superior mop lifting: between 12 and 22 mm versus 10.5 mm of the Dreame models.
The water temperature for mopping the floor marks another important distinction. The Matrix10 Ultra mops with hot water, which improves the removal of grease and stuck-on stains. The Saros 10R uses warm water, whilst the X50 Ultra Blanca is limited to cold water. In practice, this is especially noticeable in kitchens or areas with more persistent dirt.
All three models automatically remove the mops at the base when you only want to vacuum, and all detect dirt both on the mops and on the floor to adjust cleaning. The bases wash the mops with hot water and dry them with hot air, guaranteeing hygiene and preventing bad odours.
An exclusive feature of the Matrix10 Ultra is automatic mop changing: it incorporates 3 pairs of mops that the robot changes automatically when it detects they are too dirty. This is especially useful in large homes or when accumulated dirt is considerable.
Navigation System
Navigation integrates retractable LIDAR technology in both Dreame models, whilst the Saros 10R uses Roborock's StarSight 2.0 system. All three equip dual RGB camera with artificial intelligence and front 3D laser sensor, plus LED for night vision and remote camera access.
The number of recognised obstacles varies considerably. The Matrix10 Ultra identifies up to 240 different objects, the X50 Ultra Blanca reaches 200, and the Saros 10R remains at 108. This doesn't necessarily mean the Roborock navigates worse, but the Dreame models do have broader databases to recognise specific household items.
All three recognise pets and allow remote camera access. However, only the Dreame models detect curtains, which prevents the robot from getting tangled in hanging fabrics. The processor also differs: AI Sage 15.0 in the Matrix10 Ultra, AI Sage 13.0 in the X50 Ultra and RR Mason 11.0 in the Saros 10R. Each manufacturer implements its own artificial intelligence for route planning and adaptive cleaning.
Autonomy and Battery
All three robots mount 6,400 mAh batteries, but performance differs notably. The Dreame Matrix10 Ultra reaches 260 minutes of autonomy, whilst both the Saros 10R and the X50 Ultra Blanca remain at 180 minutes. This 80-minute difference is decisive in large homes or with multiple floors.
For homes over 200 square metres, the extended autonomy of the Matrix10 Ultra allows complete cleaning cycles without intermediate recharges. The other two models may need to return to the base mid-cycle on large surfaces, although this isn't a real problem thanks to automatic recharge and resumption.
Smart Functions
All three robots overcome simple steps, a useful capability for transitions between rooms or small level changes. None incorporates a robotic arm, but all include their own voice assistant in addition to compatibility with Alexa and Google Home. This allows voice control both through the manufacturer's assistants and through the most popular home ecosystems.
Multifunctional Cleaning Base
All three bases offer auto-emptying, mop washing and drying with hot water and air. Self-cleaning of the washing tray reaches 3.5 generations in the Matrix10 Ultra, 3 generations in the X50 Ultra and 2.0 in the Saros 10R. This translates into increasingly automated systems that require less manual intervention.
The detergent tank marks a notable difference: the Matrix10 Ultra incorporates a triple system that allows using different products according to floor type or dirt level. The other two models have a simple tank, sufficient but less versatile.
Only the X50 Ultra Blanca includes UV disinfection, a function that adds an additional sanitisation step although it isn't essential for most homes.
Regarding capacities, the Matrix10 Ultra and the X50 Ultra mount a 3.2-litre dust bag versus 2.5 litres of the Saros 10R. The clean water tank reaches 5.5 litres in the Matrix10 Ultra, 4.5 litres in the X50 Ultra and 4 litres in the Saros 10R. Dirty water is stored in 4 litres in the Dreame models and 3 litres in the Roborock. These differences are especially noticeable in large homes where greater capacity means fewer emptyings and refills.
Both the Matrix10 Ultra and the X50 Ultra offer an optional plumbing connection kit, which is purchased separately. The Saros 10R doesn't contemplate this option.
Dimensions
The Roborock Saros 10R stands out for its height of barely 79.8 mm, which allows it to slip under furniture where the other two cannot reach. The Matrix10 Ultra and the X50 Ultra Blanca measure 89 mm in height, a difference of almost a centimetre that can be decisive if you have very low sofas or beds.
The diameter is practically identical: 350 mm in the Dreame models and 353 mm in the Roborock. As for the bases, the X50 Ultra Blanca is the most compact in width at 340 mm, followed by the Saros 10R at 381 mm and the Matrix10 Ultra at 416 mm. The height of the bases varies between 488 mm of the Saros 10R and 590 mm of the Matrix10 Ultra, whilst the depth ranges between 456.7 mm and 475 mm.
Real-world experience
For large homes over 200 square metres, the Matrix10 Ultra offers the most complete combination: maximum power, greater autonomy, larger tanks and automatic mop changing system. Hot water mopping and the triple detergent system add versatility for different floor types.
If you live with pets, any of the three works well thanks to the anti-tangle brushes, although the greater power of the Matrix10 Ultra is advantageous for hair embedded in carpets. Dreame's HyperStream system tends to require slightly less maintenance than Roborock's DuoDivide when the amount of hair is high.
For homes with low furniture, the Saros 10R clearly wins with its 79.8 mm height. This difference of almost a centimetre compared to the Dreame models allows it to access spaces the others cannot reach, reducing uncleaned areas.
The X50 Ultra Blanca positions itself as an intermediate option: it offers good power, broad obstacle recognition, UV disinfection and the Roboswing system for edges, but without the automatic mop changing or hot water mopping of the Matrix10 Ultra. It's a balanced alternative for those seeking a complete Dreame robot vacuum without reaching the most premium model.
