Introduction
The Dreame L50s Pro Ultra and the Roborock Qrevo Edge S5A represent two high-end propositions within the robot vacuum market with multifunction base. The Dreame model arrives in 2026 with specifications that aim to be the most technically advanced, whilst the Qrevo Edge S5A from Roborock, launched in 2024, has already established itself as a reliable and comprehensive option. Both units are designed for users seeking comprehensive autonomous cleaning, combining vacuuming and mopping with minimal manual intervention. The difference in power, navigation systems and base features marks significant distances between them.
These robots are particularly useful in medium and large homes where autonomy and base capacity are determining factors for keeping the house clean without constant emptying. The presence of multifunction bases with hot air mop washing and drying guarantees effective mopping without unpleasant odours.
Power and Suction
The most notable difference in this robot vacuum comparison lies in suction power. The Dreame L50s Pro Ultra offers 30,000 Pa, a figure that far exceeds the 18,500 Pa of the Roborock Qrevo Edge S5A. This advantage translates into greater capacity to remove ingrained dirt, pet hair and fine particles in carpets or tile joints.
Regarding the brushing system, the Dreame mounts a dual HyperStream brush, specifically designed to prevent hair tangles. The Roborock uses the DuoDivide anti-tangle brush, which pushes hairs towards the central suction gap. Both systems are effective, albeit with different approaches. What makes a difference is that the Dreame can raise the main brush during mopping, preventing it from getting unnecessarily wet. The Roborock doesn't have this function.
Both units feature extendable and anti-tangle side brush, but the Dreame adds the ability to also raise the side brush during mopping. This is useful to prevent the brush from dragging dirty water towards already clean areas or wetting skirting boards.
Mopping
Both robots use two rotating mops for mopping, a system that guarantees better results than dragging mops. The Dreame incorporates mop extension with Roboswing movement, which allows the robot to make an oscillating movement to get the mop under furniture or ledges. The Roborock also has mop extension, although without the additional movement.
Mop lifting is practically identical: 10.5 mm on the Dreame and 10 mm on the Roborock. Both mop with cold water and feature dirt detection both on the mops and on the floor, which allows automatic re-mopping in dirtier areas.
An important practical difference: the Dreame can automatically remove the mops at the base when only vacuuming is desired. The Roborock doesn't have this function, which requires removing them manually if you don't want to mop. For homes where pure vacuuming alternates with mopping, this can be a decisive factor.
Navigation System
This is where the Dreame L50s Pro Ultra deploys its most advanced technological arsenal. It incorporates dual AI camera, front 3D laser sensor and night vision LED, elements that the Roborock Qrevo Edge S5A doesn't have. This allows the Dreame to recognise up to 220 different obstacles, identify pets, detect curtains and offer remote camera access for home surveillance.
The Roborock relies on its 3D LiDAR turret and the RR Mason 11.0 algorithm, together with the SmartPlan 2.0 system for intelligent route planning. It's a proven and reliable system, although less ambitious in object recognition. It doesn't have a front camera or additional 3D sensors.
In practice, the Dreame is more suitable for homes with pets or young children, where the ability to recognise specific objects and avoid accidents is more valuable. The Roborock offers efficient but more traditional navigation.
Autonomy and Battery
Both robots mount a 5,200 mAh battery. The Roborock specifies an autonomy of 180 minutes, whilst the Dreame doesn't provide this data. With the same battery capacity, it's reasonable to expect similar autonomies, although the Dreame's greater suction power could slightly reduce its operating time in maximum mode.
The absence of autonomy data on the Dreame doesn't allow for a precise assessment, but with 5,200 mAh both units are prepared for sizeable homes without the need for intermediate recharges.
Smart Features
The Dreame L50s Pro Ultra can overcome simple steps, although the exact height isn't specified. The Roborock Qrevo Edge S5A overcomes obstacles up to 20 mm, a concrete figure that makes it easier to know if it will be able to navigate thick carpets or level differences between rooms.
The Dreame integrates its own voice assistant, in addition to compatibility with Alexa and Google Home. The Roborock only offers compatibility with external assistants. This may be interesting for those who prefer to control the robot without depending on third-party ecosystems, although in practice most users use Alexa or Google.
Multifunction Cleaning Base
Both bases are complete multifunction: they auto-empty dust, wash mops with hot water and dry them with hot air. The Dreame incorporates 3rd generation tray self-cleaning, whilst the Roborock uses version 2.0. This means that the Dreame base stays cleaner autonomously, reducing manual maintenance.
The Dreame includes a detergent tank in the base, something the Roborock doesn't offer. This allows the base to automatically dispense product during mop washing, improving mopping hygiene without user intervention.
The dust bag capacity is 3.2 litres in the Dreame compared to 2.7 litres in the Roborock. The clean water tanks are 4.5 litres and 4 litres respectively, whilst the dirty water ones reach 4 litres in the Dreame and 3.5 litres in the Roborock. These differences are moderate, but the Dreame offers somewhat more autonomy between emptying and refilling.
The Dreame allows the purchase of an optional plumbing connection kit, although it doesn't come integrated as standard. The Roborock doesn't have this option. For those seeking maximum automation, this possibility may be interesting in the long term.
Dimensions
The Roborock Qrevo Edge S5A measures 98 mm in height, which allows it to slip under furniture more easily than the Dreame L50s Pro Ultra, which reaches 103.8 mm. This difference of almost 6 mm can be determining in homes with low sofas or beds with little separation from the floor.
The diameter is practically identical: 350 mm on the Dreame and 352 mm on the Roborock. As for the bases, the Dreame is taller (590 mm compared to 521 mm) but less deep (457 mm compared to 487 mm). Both have the same width of 340 mm. It's advisable to measure the available space before deciding, especially if it's going to be placed under furniture or in a tight gap.
Real-World Experience
The Dreame L50s Pro Ultra is more suitable for large homes with pets, thanks to its greater suction power, dual anti-tangle brush and ability to recognise animals. The possibility of raising the main and side brush during mopping, together with automatic mop removal, makes it a very versatile option for those who alternate vacuuming and mopping according to needs.
The Roborock Qrevo Edge S5A stands out for its lower height, which facilitates cleaning under furniture. Its dust bin in the robot is larger (325 ml compared to 250 ml), which can be useful in homes with a lot of daily dirt. Navigation is reliable and proven, although without the advanced recognition features of the Dreame.
For homes where total automation is a priority, the Dreame's detergent tank and its 3rd generation tray self-cleaning reduce maintenance. The Roborock requires adding detergent manually if you wish to use it during mop washing.
Conclusion: Which One to Choose?
Choose the Dreame L50s Pro Ultra if: You're looking for the best robot vacuum 2025 with maximum suction power, advanced object and pet recognition, and a base with detergent tank and latest generation self-cleaning. It's ideal for large homes with pets, where total automation and minimal manual intervention are priorities. Also if you value remote camera access or automatic mop removal.
Choose the Roborock Qrevo Edge S5A if: You prefer a Roborock robot vacuum with reduced height to clean under low furniture, larger dust bin in the robot and a proven and reliable navigation system. It's an excellent option for those seeking a balance between advanced features and ease of use, without the need for pet recognition functions or camera access. Its value for money is very competitive within the high-end range.
Ultimately, the differences between both models focus on the level of automation and intelligent recognition. The Dreame opts for the most advanced technology, whilst the Roborock offers a solid and effective proposition with more compact dimensions.
