Introduction
The Dreame L50 Ultra AE and the Roborock Qrevo Curv 2 Pro represent two distinct propositions within the high-end robot vacuum cleaners with multifunction base. The Dreame model, launched in 2026, positions itself as a competitive alternative to the Roborock Qrevo Curv 2 Pro, which arrived on the market in 2025. Both units include advanced vacuuming and mopping functions, although each manufacturer has opted for different approaches in terms of artificial intelligence, navigation and storage capacity.
The Dreame L50 Ultra AE stands out for its high suction power and a TriCut 3.0 brushing system, whilst the Roborock Qrevo Curv 2 Pro relies heavily on artificial intelligence with dual camera and advanced object recognition. This robot vacuum cleaner comparison will help to understand which model is better suited to the needs of each home.
Power and Suction
Suction power is one of the aspects where the Dreame robot vacuum cleaner takes the lead. With 28,000 Pa, it exceeds the Roborock Qrevo Curv 2 Pro by 3,000 Pa. This difference can be particularly noticeable on carpets or when there is ingrained dirt.
As for the main brush, the Dreame L50 Ultra AE features the TriCut 3.0 system, which combines bristles with blades designed to cut tangled hair. The Roborock Qrevo Curv 2 Pro uses the DuoDivide Antienredos brush, which pushes hair towards the central gap to facilitate suction. Both systems are designed to reduce tangles, albeit with different philosophies.
Both models raise the main brush during mopping to prevent it from getting wet. They also share an extendable and anti-tangle side brush, which improves cleaning in corners and reduces maintenance. Neither raises the side brush during mopping nor includes a specific brush for skirting boards.
Mopping
Both robot vacuum cleaners use two rotating mops for mopping. The Dreame L50 Ultra AE incorporates mop extension with the Roboswing system, which allows the robot to perform a lateral movement to get the mop under furniture or overhangs. The Roborock Qrevo Curv 2 Pro also extends its mops to better reach edges.
Mop lifting differs between the two. The Dreame reaches 10.5 mm, whilst the Roborock offers a range of 7 to 17 mm, giving it greater flexibility depending on the type of surface. This capability is useful when the robot moves from hard floor to carpet.
An important difference appears in dirt detection. The Roborock Qrevo Curv 2 Pro detects dirt on both the mops and the floor, allowing it to automatically re-mop particularly dirty areas. The Dreame L50 Ultra AE does not include this function.
Both bases wash the mops with hot water and dry them with hot air, which helps to keep them hygienic and odour-free. They also allow the mops to be automatically removed at the base when only vacuuming is desired. The self-cleaning system for the washing tray is present in both models, with third-generation technology.
Navigation System
Here we find notable differences between the Roborock robot vacuum cleaner and the Dreame. The Dreame L50 Ultra AE uses a traditional 3D LiDAR turret to map the home, complemented with a front 3D laser sensor to avoid obstacles. It does not incorporate an artificial intelligence camera.
The Roborock Qrevo Curv 2 Pro opts for a retractable LiDAR and adds a dual AI camera capable of recognising up to 200 different types of obstacles. It includes specific pet recognition, LED for night vision and remote camera access. Additionally, it integrates the SmartPlan 3.0 system for intelligent cleaning and stain recognition using artificial intelligence.
For homes with pets or many objects on the floor, the Roborock navigation system offers clear advantages. The Dreame, without a camera, relies exclusively on its 3D laser sensors, which work well but without the level of visual detail that a camera provides.
Autonomy and Battery
The Roborock Qrevo Curv 2 Pro features a 6,400 mAh battery that provides up to 290 minutes of autonomy. This capacity is particularly useful in large homes where the robot needs to complete the entire cleaning without recharging.
The Dreame L50 Ultra AE is equipped with a 5,200 mAh battery, lower in capacity. The autonomy data in minutes is not available for this model, although the difference of 1,200 mAh suggests it will be less than the Roborock.
In practice, both robots automatically return to the base if they need to recharge during cleaning and resume work where they left off.
Smart Functions
The ability to overcome obstacles is another differentiating point. The Dreame L50 Ultra AE can overcome steps up to 20 mm in height. The Roborock Qrevo Curv 2 Pro goes further with its simple step system, although the exact height it can overcome is not specified.
The Roborock includes its own voice assistant, which allows commands to be given directly to the robot without needing to use a mobile phone. The Dreame L50 Ultra AE does not incorporate this function, although both models are compatible with external assistants such as Alexa or Google Home.
Multifunction Cleaning Base
Both bases are complete multifunction: they auto-empty the dust container, wash and dry the mops with hot water and air, and feature third-generation self-cleaning of the washing tray.
The Dreame L50 Ultra AE incorporates a detergent tank in the base, something the Roborock Qrevo Curv 2 Pro does not offer. This allows the Dreame to automatically dispense cleaning product during mop washing, improving hygiene without manual intervention.
In terms of storage capacities, the Dreame dust bag has 3.2 litres compared to the Roborock's 2.5 litres. The clean water tanks also favour the Dreame: 4.5 litres against 4 litres. The Dreame dirty water tank reaches 4 litres, whilst the Roborock's remains at 3 litres.
The Dreame offers an optional plumbing connection kit that is purchased separately, allowing the base to be connected directly to the home's water system. The Roborock does not have this option.
Dimensions
The diameter of both robots is practically identical: 350 mm for the Dreame and 352 mm for the Roborock. The important difference is in height. The Roborock Qrevo Curv 2 Pro measures only 79.8 mm, which allows it to slip under low furniture more easily. The Dreame L50 Ultra AE reaches 97 mm in height, almost 2 centimetres more.
This height difference can be decisive in homes with sofas, beds or furniture with little clearance from the floor. The Roborock will access spaces where the Dreame will not reach.
The internal tanks of the robot are similar: 250 ml of dust in the Dreame compared to 245 ml in the Roborock, and 80 ml of water in the Dreame against 67 ml in the Roborock.
The bases also differ in size. The Dreame measures 340 mm wide, 590 mm high and 457 mm deep. The Roborock is more compact in height but wider: 450 mm in all three dimensions, forming practically a cube. It is advisable to measure the available space before deciding.
Real-world usage experience
For large homes, the Roborock Qrevo Curv 2 Pro offers greater autonomy thanks to its 6,400 mAh battery and 290 minutes of operation. Its slightly smaller water tanks may require refilling more frequently, although the difference is not drastic.
In homes with pets, the Roborock navigation system makes the difference with its specific animal recognition and ability to identify up to 200 obstacles. The Dreame offers greater suction power, which helps with ingrained hair, but lacks advanced visual recognition.
If the home has many low furniture pieces, the Roborock's 79.8 mm height allows it to access spaces forbidden to the Dreame. This advantage is particularly noticeable in day-to-day use.
The Dreame detergent tank provides convenience by fully automating the mopping process without the need to add product manually. For those seeking maximum autonomy in mopping, this detail adds value.
The Roborock dirt detection, on both mops and floor, allows the robot to automatically re-clean areas that need it. This improves the final mopping result without user intervention.
Conclusion: Which to choose?
Choose the Dreame L50 Ultra AE if: You seek maximum suction power with 28,000 Pa, you value having an automatic detergent tank in the base, you need larger water tanks (4.5 litres of clean water) and you prefer a higher capacity dust bag (3.2 litres). Also if you are interested in the future option of connecting the base to plumbing via an optional kit.
Choose the Roborock Qrevo Curv 2 Pro if: You need to access under low furniture thanks to its 79.8 mm height, you value artificial intelligence with dual camera and recognition of up to 200 obstacles, you have pets and want specific animal recognition, you seek greater autonomy with 290 minutes of battery, you want remote camera access with night LED, or you prefer a system that automatically detects dirt to re-mop problematic areas. The built-in voice assistant also adds convenience to daily use.
Ultimately, the choice depends on whether you prioritise raw power and storage capacity (Dreame) or advanced artificial intelligence, autonomy and access under furniture (Roborock). Both are high-end robot vacuum cleaners with complete multifunction bases, but each excels in different aspects depending on the user profile.
