Introduction
The Dreame L50 Pro Ultra arrives on the market in 2025 as an ambitious proposition from the Chinese manufacturer, whilst the Roborock Qrevo Curv and Qrevo Curv S5X were introduced in 2024 as part of the high-end range from the leading robot vacuum brand. All three units incorporate multifunctional bases that wash and dry the mops with hot water and air, albeit with notable differences in capabilities and advanced functions.
The Dreame model targets users seeking maximum autonomy and cutting-edge technology, especially in homes with pets and demanding cleaning needs. The two Roborock models differ from each other primarily in equipment: the Qrevo Curv includes an AI camera and advanced sensors, whilst the S5X offers a more accessible version without sacrificing the laser navigation system and professional mopping.
Power and Suction
The Dreame L50 Pro Ultra leads in raw power with 19,500 Pa, exceeding the two Roborock Qrevo Curv models by 1,000 Pa. This difference can be particularly noticeable on medium-pile carpets or when vacuuming heavier debris embedded in complex textures.
Regarding brushes, the Dreame incorporates a HyperStream dual brush system designed to minimise tangling of long hair, whilst both Roborock models mount the DuoDivide anti-tangle brush that pushes hair towards the central suction gap. Both solutions prove effective with pets, albeit with different technical approaches.
All three models lift the main brush during mopping, except the Qrevo Curv S5X which keeps the brush fixed. This means the S5X cannot prevent the brush from touching the wet floor, something that both the Dreame and standard Qrevo Curv do achieve.
The extendable side brush is present on all three robots, improving corner cleaning. However, only the Dreame L50 Pro Ultra can lift this side brush during mopping, preventing it from interfering with the wet mops or projecting dirty water droplets. This function adds precision to edge mopping work.
Mopping
All three units use two rotating mops that extend towards the edges to reach skirting boards and corners. The Dreame adds the Roboswing system, which performs a lateral movement of the robot to slightly introduce the mop under furniture or overhangs, something the Roborock models don't implement.
Mop lifting varies: the Qrevo Curv reaches between 10 and 20 mm depending on the surface, the Dreame reaches 10.5 mm and the S5X stays at 10 mm. These differences matter when transitioning from hard floor to carpets or mats: the higher the mops lift, the lower the risk of wetting them.
An exclusive advantage of the Dreame is automatic mop removal at the base. When you only want to vacuum without mopping, the robot leaves the mops at the station and goes out to work without them. The Roborock models keep the mops raised during vacuuming, but they remain mounted on the robot.
All three models wash the mops at the base with hot water and dry them with hot air, ensuring hygiene and preventing bad odours. Self-cleaning of the washing tray is also present in all: the Dreame boasts third generation of this technology, whilst the Roborock models incorporate version 2.0. All detect dirt both on the mops and on the floor to reinforce mopping when necessary.
Navigation System
The Dreame L50 Pro Ultra mounts a retractable LiDAR that hides inside the chassis, reducing the robot's total height to 89 mm. The two Roborock models maintain the traditional LiDAR turret, raising the height to 103 mm on the Qrevo Curv and 98 mm on the S5X. For homes with low furniture or sofas with little clearance, those millimetres make the difference between accessing or staying out.
The Dreame and Qrevo Curv integrate dual AI camera and front 3D laser sensor for advanced obstacle recognition. The Qrevo Curv S5X does without these cameras, limiting its ability to identify specific objects. In practice, this means the S5X avoids obstacles using basic sensors, but cannot recognise whether it's a shoe, a cable or a toy.
The Dreame stands out with the ability to recognise 180 different types of obstacles thanks to its AI Sage 13.0 processor, compared to 62 for the Qrevo Curv with RR Mason 11.0. This difference translates into greater precision when identifying objects and adapting cleaning. The Dreame also detects curtains, something the Roborock models don't do, avoiding tangles with hanging fabrics.
Both the Dreame and Qrevo Curv offer remote camera access and LED for night vision, allowing you to monitor the home from your mobile. The S5X doesn't have these functions as it lacks a camera. Pet recognition is present on the Dreame and Qrevo Curv, facilitating monitoring of domestic animals during cleaning.
Autonomy and Battery
The Qrevo Curv leads in autonomy with 240 minutes of continuous operation, followed by the Dreame with 200 minutes and the Qrevo Curv S5X with 180 minutes. Both Qrevo Curv and Dreame mount 6,400 mAh batteries, but the Curv optimises energy consumption better. The S5X reduces capacity to 5,200 mAh, which explains its lower autonomy.
For homes over 200 square metres, the Qrevo Curv offers greater safety margin. The Dreame covers surfaces of up to 180-190 square metres without problems, whilst the S5X is better suited to medium-sized homes, between 120 and 150 square metres.
Smart Functions
The ability to overcome steps varies considerably. The Qrevo Curv jumps obstacles of up to 40 mm thanks to its adaptive wheel system, overcoming thick carpets and raised thresholds without getting stuck. The Dreame reaches 30 mm, sufficient for most transitions between rooms. The S5X is limited to 20 mm, being more exposed to blockages on high-pile carpets or pronounced level changes.
The Dreame L50 Pro Ultra and Qrevo Curv incorporate their own voice assistant integrated into the robot, in addition to compatibility with Alexa and Google Home. The S5X only works with external assistants, without its own voice. This allows the first two to respond to commands directly without the need for additional devices.
Multifunctional Cleaning Base
All three bases perform auto-emptying of the dust bin, mop washing with hot water and drying with hot air. The main difference lies in the detergent tank: only the Dreame includes it, dispensing cleaning product during mop washing. The Roborock models wash only with hot water, without adding detergent automatically.
Storage capacity favours the Dreame: 3.2-litre dust bag compared to 2.5 litres on the Roborock models, 4.5-litre clean water tank compared to 4 litres, and 4-litre dirty water tank compared to 3 litres. This translates into greater autonomy between manual emptying and refilling, especially useful in large homes or with pets that create more mess.
The Dreame offers an optional kit for connection to water pipes, although it must be purchased separately. The Roborock models don't have this option. In any case, none of the three integrate direct connection to pipes as standard.
Dimensions
The Dreame L50 Pro Ultra measures 89 mm in height, making it the lowest of the three and facilitating access under sofas, beds and furniture with little separation from the floor. The Qrevo Curv S5X reaches 98 mm and the Qrevo Curv reaches 103 mm due to its more prominent LiDAR turret. All three have similar diameters: 350 mm for the Dreame and 352 mm for both Roborock models.
The bases also differ in size. The Dreame's measures 340 mm wide, 456.7 mm deep and 590.5 mm high, with a more vertical shape. The Roborock bases are square: 450 mm in all three dimensions, occupying more floor surface but less height. This should be considered depending on the available space to install the cleaning station.
Real-World User Experience
In homes with pets, the Dreame L50 Pro Ultra offers clear advantages: greater suction power, advanced recognition of 180 obstacles including animals, detergent tank to sanitise the mops and greater storage capacity at the base. The Qrevo Curv also manages environments with animals well thanks to its DuoDivide brush and pet recognition, albeit without automatic detergent.
For large homes, the Qrevo Curv stands out for its 240 minutes of autonomy and ability to overcome 40 mm steps, ideal if there are multiple thick carpets or level changes. The Dreame compensates with larger tanks at the base, reducing manual interventions.
If the home has many low pieces of furniture, the Dreame accesses better thanks to its 89 mm height. This difference of up to 14 mm compared to the Qrevo Curv can mean cleaning or not under certain furniture.
The Qrevo Curv S5X positions itself as a more straightforward option: without AI camera or its own voice assistant, but maintaining the professional mopping system with extendable mops, washing and drying with hot air. It's suitable for those who prioritise effective cleaning without needing camera surveillance or advanced object recognition.
