Introduction
The Dreame L50s Pro Ultra and the Roborock Qrevo S Pro represent two high-end propositions within the robot vacuum cleaner market with multifunction base. The Dreame model, launched in 2026, opts for the most advanced technology with a suction power of 30,000 Pa, whilst the Qrevo S Pro from Roborock, presented in April 2026, offers 18,500 Pa with the brand's characteristic quality seal.
We are looking at two units designed for users seeking to fully automate home cleaning. The Dreame incorporates a double HyperStream brush, whilst the Roborock maintains a single DuoDivide brush. The differences go beyond power: navigation systems, tank capacity, intelligent functions and mopping features mark notable distances between these models.
Power and Suction
The power difference between these robots is significant. The Dreame L50s Pro Ultra reaches 30,000 Pa, a figure that widely exceeds the 18,500 Pa of the Roborock Qrevo S Pro. This advantage translates into better performance on thick carpets and in the ability to vacuum more embedded particles.
The brushing system marks another important distinction. The Dreame equips a double HyperStream brush, designed with two brushes anchored at one end that minimise hair tangles. The Roborock uses a single DuoDivide brush, which pushes hairs towards the central suction gap. Both systems are anti-tangle, but the technical approach differs.
A notable advantage of the L50s Pro Ultra is the automatic lifting of the main brush during mopping, a function that the Qrevo S Pro does not offer. This prevents the brush from getting unnecessarily wet and allows more efficient mopping. The Dreame's side brush also lifts and features extension to better reach corners, characteristics absent in the Roborock model. In practice, these functions make a difference when cleaning skirting boards and corners.
Mopping
Both robots mount two rotating mops, but the mopping system of the Dreame L50s Pro Ultra incorporates more technology. The mop extension with Roboswing movement allows the robot to slightly insert the mop under furniture and overhangs through a lateral movement. The Roborock does not have this function.
Mop lifting reaches 10.5 mm on the Dreame and 10 mm on the Qrevo S Pro, a minimal difference that is not decisive. Both wash the mops with hot water at the base and dry them with hot air, guaranteeing hygiene and preventing bad odours.
The Dreame stands out for its ability to automatically remove the mops at the base when only vacuuming is desired, avoiding having to remove them manually. The Roborock requires manual intervention for this task. Dirt detection on mops and on the floor is exclusive to the L50s Pro Ultra, allowing the robot to identify dirtier areas and act accordingly by scrubbing or rewashing the mops when necessary.
Navigation System
Both robots integrate 3D LiDAR turret and obstacle avoidance, but the Dreame L50s Pro Ultra incorporates a more complete arsenal of sensors. It equips dual AI camera, front 3D laser sensor and night vision LED, elements that the Roborock Qrevo S Pro does not include.
This difference is especially noticeable in object recognition. The Dreame identifies up to 220 different obstacles, including pets and curtains, something that the Qrevo S Pro cannot do with the same precision. Remote access to the L50s Pro Ultra's camera allows monitoring the home from the mobile application, a function absent in the Roborock model.
The Dreame's front LED improves navigation in low-light conditions, whilst the Roborock depends exclusively on the laser. Both models feature AI-based intelligent cleaning systems: CleanGenius on the Dreame and SmartPlan 2.0 on the Roborock. AI stain recognition is exclusive to the L50s Pro Ultra.
Autonomy and Battery
The battery capacity is identical in both: 5,200 mAh. The Roborock Qrevo S Pro specifies an autonomy of 180 minutes, data that the Dreame does not detail in its technical specifications. In practice, with batteries of equal capacity, real autonomy will depend on the cleaning mode and power used.
The Dreame's greater power could imply higher consumption when used at maximum, although this need not affect everyday use if the robot automatically adjusts power according to surface type.
Intelligent Functions
The Dreame L50s Pro Ultra overcomes single steps up to a certain height, whilst the Roborock Qrevo S Pro specifies capacity for 20 mm obstacles. This difference may be relevant in homes with small level changes between rooms or thick carpets.
The Dreame's own voice assistant allows direct interaction with the robot without the need for intermediaries. The Roborock does not include its own assistant, although both are compatible with Alexa and Google Home. For users who value privacy or prefer not to depend on external ecosystems, the Dreame's integrated assistant represents an advantage.
Multifunction Cleaning Base
Both bases are complete multifunction: they auto-empty the dust container, wash the mops with hot water and dry them with hot air. The Dreame L50s Pro Ultra incorporates third-generation washing tray self-cleaning, a function that the Qrevo S Pro does not offer. This significantly reduces manual maintenance of the base.
The detergent tank is present only on the Dreame, allowing cleaning product to be added which is dispensed during mop washing. The Roborock lacks this option. The dust bag capacity reaches 3.2 litres on the L50s Pro Ultra versus 2.7 litres on the Qrevo S Pro.
The clean and dirty water tanks are also larger on the Dreame: 4.5 and 4 litres respectively, versus 4 and 3.5 litres on the Roborock. For large homes, these differences can translate into fewer refills and emptying. The Dreame's optional plumbing connection kit allows complete automation of water filling and emptying, although it is purchased separately.
Dimensions
The Roborock Qrevo S Pro measures 96.5 mm in height, versus the 103.8 mm of the Dreame L50s Pro Ultra. This difference of more than 7 mm can be decisive for passing under low furniture. The diameter is practically identical: 350 mm on the Dreame and 353 mm on the Roborock.
The Dreame's base is taller (590 mm versus 519 mm) but less deep (457 mm versus 487 mm). It is advisable to measure the available space before deciding, especially if planning to locate the base under furniture or in a specific gap.
Real-World User Experience
The Dreame L50s Pro Ultra is designed for users seeking maximum automation and technology. The combination of high power, double anti-tangle brush, dirt detection and tray self-cleaning makes it an ideal option for large homes with pets. Specific animal recognition and the remote camera add value for those wanting to monitor their pets.
The Roborock Qrevo S Pro is more suitable for those prioritising passing under low furniture thanks to its lower height. Its power of 18,500 Pa remains high for most homes, and Roborock's reliability as a world-leading brand provides peace of mind. The lower technological complexity can translate into fewer elements susceptible to long-term failures.
For homes with thick carpets or heavy dirt accumulation, the Dreame's extra power makes a difference. If the home has mainly hard floors and dimensional discretion is valued more, the Roborock gains points. The Dreame's automatic mop removal simplifies use when only vacuuming is desired, avoiding constant manipulation.
Conclusion: Which to Choose?
Choose the Dreame L50s Pro Ultra if: you seek maximum suction power and the most complete technological equipment. It is the option for large homes with pets, where dirt detection, recognition of more than 200 obstacles and tray self-cleaning minimise maintenance. The detergent tank, larger water tanks and possibility of plumbing connection make it the most autonomous robot. If you value the remote camera and own voice assistant, this model offers features that the Roborock does not match.
Choose the Roborock Qrevo S Pro if: you need to pass under low-height furniture and prefer the reliability of the world-leading brand in robot vacuum cleaners. Its lower height of 96.5 mm and Roborock's reputation for build quality and mobile application are solid arguments. For homes where 18,500 Pa of power is sufficient and advanced AI functions such as pet recognition or curtain detection are not required, this model offers excellent performance with lower technical complexity. The relationship between essential features and compact dimensions makes it ideal for medium-sized flats without special monitoring needs.
