Introduction
The Dreame X50 Ultra Blanca and the Roborock Qrevo Edge S5A represent two high-end propositions launched in consecutive years. The former arrived on the market in 2025 with the intention of pushing technological boundaries, whilst the Roborock model, introduced in 2024, had already established a high standard in performance. Both units feature a multifunction base that washes and dries the mops, as well as automatic dust emptying, making them options designed for users seeking complete automation and minimal manual maintenance.
We are looking at robots designed for medium and large homes, with the capacity to manage different types of flooring and obstacles. The main difference lies in the level of artificial intelligence, detection systems and some specific functions that may influence the choice depending on each household's needs.
Power and Suction
Suction power marks a notable difference. The Dreame X50 Ultra Blanca develops 20000 Pa in Turbo mode, whilst the Roborock Qrevo Edge S5A remains at 18500 Pa. This advantage can prove decisive on medium or long pile carpets, where each additional Pascal contributes to extracting more embedded dirt.
Regarding the brushing system, the Dreame mounts a dual anti-tangle brush and the Roborock uses its DuoDivide technology, also anti-tangle. Both systems are designed to minimise hair accumulation, something fundamental in homes with pets. Both models include an extendable and anti-tangle side brush, which improves cleaning in corners and edges.
Where an important functional difference appears is in brush elevation. The Dreame X50 Ultra Blanca can raise both the main brush and the side brush during mopping, preventing the brushes from touching the wet floor and guaranteeing cleaner mopping without dragging dirt. The Roborock Qrevo Edge S5A does not raise the main brush, although it does raise the side brush. In practice, this can be particularly noticeable when alternating between vacuuming and mopping zones in the same pass.
Mopping
Both robots employ a two rotating mop system, which offers more effective mopping than traditional drag mops. Both models feature mop extension to better reach edges: the Dreame incorporates its 3.0 system with Roboswing, which adds a lateral movement to get the mop under overhangs and furniture; the Roborock uses FlexiArm, its own lateral extension technology.
Mop elevation is slightly superior in the Dreame, with 10.5 mm compared to the Roborock's 10 mm. It may seem a minimal difference, but it helps to better protect short pile carpets. More relevant is the mop washing temperature: the Dreame washes at 80°C, whilst the Roborock does so at 75°C. Those extra five degrees contribute to better eliminating grease and bacteria adhered to the mops. Both dry the mops at 45°C, guaranteeing efficient drying that prevents bad odours.
The Dreame X50 Ultra Blanca allows leaving the mops at the base when only vacuuming is desired, a function the Roborock does not offer. This proves practical if you want to do a quick dust clean without dampening the floor. Both units detect dirt on the mops and on the floor to adjust mopping, rewashing or rescrubbing dirtier zones automatically.
Navigation System
Here we find substantial differences. The Dreame X50 Ultra Blanca mounts a retractable LIDAR system combined with dual AI camera and front 3D laser sensor. This configuration allows it to recognise up to 200 different types of obstacles, including pets and curtains, something the Roborock does not do. Additionally, the Dreame incorporates night vision LED and remote camera access, useful functions for surveillance or simply to see what the robot is doing in real time.
The Roborock Qrevo Edge S5A uses LIDAR 3.0 turret with obstacle avoidance, but without AI camera. This does not mean it navigates worse, but it does lack the capacity to identify specific objects with the Dreame's precision. For homes with pets that leave toys on the floor, or with small children, the Dreame's dual camera provides a real advantage.
Both robots integrate intelligent cleaning systems based on AI: the Dreame employs CleanGenius with AI Sage 13.0 Octa-core processor, whilst the Roborock uses SmartPlan 2.0 with RR Mason 11.0 algorithm. The Dreame adds stain recognition through AI, allowing automatic identification and retracing of zones with visible dirt.
Autonomy and Battery
The Dreame X50 Ultra Blanca's battery has 6400 mAh, clearly superior to the Roborock Qrevo Edge S5A's 5200 mAh. However, both offer the same declared autonomy: 180 minutes. This suggests that the Dreame, with greater suction power and more active systems (cameras, sensors), consumes more energy and balances its greater battery capacity.
For homes of up to 200-250 square metres, either of the two can complete cleaning in a single charge. On larger surfaces, the Dreame's greater battery capacity can translate into fewer interruptions for recharging, especially if high suction modes are used.
Intelligent Functions
The capacity to overcome obstacles varies considerably. The Dreame X50 Ultra Blanca can overcome obstacles of 42 to 60 mm thanks to an extra system, whilst the Roborock Qrevo Edge S5A is limited to 20 mm. This difference proves crucial if there are thick carpets, high thresholds or cables on the floor. The Dreame will be able to pass over them without problems, whilst the Roborock may become blocked in some cases.
The Dreame incorporates its own voice assistant, although simple. The Roborock does not include this function. Neither of the two mounts a robotic arm, technology that has not yet become widespread in these models.
Multifunction Cleaning Base
The bases of both robots include self-cleaning of the washing tray, but the Dreame boasts having its third generation of this system, compared to the Roborock's version 2.0. In practice, this translates into less manual maintenance of the tray where the mops are washed.
The Dreame X50 Ultra Blanca adds UV disinfection and detergent tank, two features absent in the Roborock. UV disinfection helps eliminate bacteria in the tray and the mops, something interesting for homes with small children or allergy sufferers. The detergent tank allows the base to add cleaning product automatically during mop washing, without the need to do so manually.
Storage capacity also favours the Dreame: dust bag of 3.2 litres compared to 2.7 litres, clean water tank of 4.5 litres compared to 4 litres, and dirty water of 4 litres compared to 3.5 litres. These differences mean greater autonomy between maintenance. Additionally, the Dreame offers an optional kit for plumbing connection, which the Roborock does not have available.
Dimensions
The Dreame X50 Ultra Blanca measures 89 mm in height, whilst the Roborock Qrevo Edge S5A reaches 98 mm. Those 9 millimetres of difference can prove decisive for passing under some furniture, sofas or beds. If you have low furniture, the Dreame will access zones where the Roborock will not enter.
The diameter is practically identical: 350 mm in the Dreame, 352 mm in the Roborock. Regarding the bases, the Dreame's is taller (590.5 mm compared to 521 mm) but less deep (456.7 mm compared to 487 mm). It is advisable to measure the available space before deciding, although both bases have similar dimensions in width (340 mm).
The robot's dust bin also varies: 395 ml in the Dreame, 325 ml in the Roborock. Although both self-empty into the base, a larger bin in the robot can be useful if cleaning a very dirty zone all at once.
Real-World Usage Experience
For large homes, the Dreame X50 Ultra Blanca offers clear advantages: greater battery capacity, larger tanks in the base and better capacity to overcome obstacles. If you have a multi-storey house with carpets of different heights, the Dreame's elevation system and its capacity to overcome obstacles of up to 60 mm makes the difference.
In homes with pets, both robots work well thanks to their anti-tangle brushes. However, the Dreame adds specific pet recognition through its cameras, which can help avoid accidents with water bowls or toys. The superior suction power also helps collect more hair embedded in carpets.
If you seek total automation with minimum maintenance, the Dreame stands out for its automatic detergent tank, UV disinfection, greater tank capacity and the plumbing connection option. The Roborock requires a bit more manual attention, although it remains a very autonomous unit.
For those who value passing under furniture, the Dreame wins with its 89 mm height. If you have low beds or sofas, this difference can mean cleaning zones that would otherwise remain inaccessible.
Conclusion: Which to Choose?
Choose the Dreame X50 Ultra Blanca if: You seek the maximum technology available in 2025, with dual AI camera, pet recognition, night LED and remote camera access. Also if you need to overcome high obstacles (up to 60 mm), pass under low furniture (89 mm height), or prefer total automation with detergent tank and UV disinfection. It is ideal for large houses with pets, thick carpets and users who want to completely forget about maintenance.
Choose the Roborock Qrevo Edge S5A if: You prefer a brand with established track record and do not need advanced functions such as cameras or specific object recognition.
