Introduction
Choosing a robot vacuum with mopping can be complicated when comparing models from different ranges. The Dreame D20 Pro Plus arrives in 2025 as an option that seeks to balance features and price, whilst the Roborock Qrevo Curv, launched in 2024, positions itself as a high-end device with advanced technology. We're talking about two different philosophies: the Dreame model focuses on extended autonomy and storage capacity, whilst the Roborock integrates artificial intelligence and a more comprehensive mopping system.
The Dreame D20 Pro Plus is interesting for those seeking a robot that covers large surfaces without the need for frequent recharging. The Roborock Qrevo Curv, on the other hand, is designed for users who prioritise deep mopping and the ability to navigate obstacles with greater precision. The differences between both models are notable and directly affect the daily cleaning experience.
Power and Suction
The power difference is significant. The Roborock Qrevo Curv reaches 18,500 Pa, exceeding the Dreame D20 Pro Plus by 5,500 Pa. This greater suction capacity translates into better performance on carpets and in picking up ingrained dirt. For homes with carpets or long-pile rugs, this advantage is decisive.
The main brush system also marks important differences. The Dreame D20 Pro Plus features a dual HyperStream brush, specifically designed to prevent hair tangles. The Roborock Qrevo Curv uses the DuoDivide anti-tangle system, which pushes hairs towards the central gap to facilitate suction. Both approaches work well with pets, albeit with different philosophies.
A clear advantage of the Roborock is the lifting of the main brush during mopping. This allows the mops to work without the brush interfering, improving the final result. The Dreame D20 Pro Plus does not incorporate this function, which can affect mopping quality in combined passes.
Regarding side brushes, both include extendable and anti-tangle design. Neither lifts the side brush, a feature only found in very specific models on the market.
Mopping
Here we find one of the most important differences in this comparison. The Dreame D20 Pro Plus uses a static mop without extension or lifting capability. Its water tank reaches 350 ml, a generous figure that allows covering large surfaces, but the mopping system is basic.
The Roborock Qrevo Curv integrates two rotating mops that extend to reach edges and corners. Additionally, it lifts the mops between 10 and 20 mm when it detects carpets or when it only needs to vacuum. This capability prevents wetting unwanted surfaces and notably improves the device's versatility. Its water tank is 80 ml, smaller than the Dreame's, but compensates for this limitation with the automatic mop washing system in the base.
Dirt detection is another exclusive function of the Roborock Qrevo Curv. The robot identifies particularly dirty areas both on the mops and on the floor, automatically scrubbing until achieving an optimal result. The Dreame D20 Pro Plus lacks this technology.
The fundamental difference lies in the base. The Roborock washes the mops with hot water during cleaning and dries them with hot air upon completion, keeping the mops clean and preventing bad odours. The Dreame D20 Pro Plus incorporates neither washing nor drying of mops, which requires frequent manual maintenance.
Navigation System
Both robots use 3D LiDAR turret to map the environment, but the difference in artificial intelligence is notable. The Roborock Qrevo Curv integrates dual camera with AI capable of recognising up to 62 different types of obstacles, including pets. The SmartPlan 2.0 system automatically adjusts routes and cleaning strategies according to room type and detected dirt.
The Dreame D20 Pro Plus does not incorporate a camera. Its navigation is based on LiDAR and front 3D laser sensors, sufficient to avoid basic obstacles but without specific recognition capability. This may translate into a greater number of manual interventions when there are small objects on the floor.
The Roborock's remote camera access allows supervising cleaning in real time and using the robot as a surveillance camera. The night vision LED facilitates navigation in low-light conditions. The Dreame lacks these functions.
Autonomy and Battery
The Dreame D20 Pro Plus stands out with a 5,200 mAh battery that provides up to 285 minutes of autonomy. This figure makes it a solid option for homes over 200 square metres, where it can complete cleaning without the need for intermediate recharging.
The Roborock Qrevo Curv features a 6,400 mAh battery, superior in capacity, but its declared autonomy is 240 minutes. The difference is explained by the higher energy consumption derived from the higher suction power and active mopping system with rotating mops.
In practice, both robots offer sufficient autonomy for most homes. The Dreame offers more minutes of continuous operation, whilst the Roborock compensates with greater power and cleaning efficiency per pass.
Smart Functions
The ability to overcome obstacles differs between both models. The Dreame D20 Pro Plus can overcome steps up to 20 mm, a standard figure that allows navigating thick carpets and small level changes. The Roborock Qrevo Curv incorporates a specific system for simple steps, although the table does not specify the exact height.
The Roborock Qrevo Curv includes its own voice assistant, in addition to compatibility with Alexa and Google Home. This allows controlling the robot through voice commands without needing to open the app. The Dreame D20 Pro Plus only offers compatibility with external assistants, without integrated voice of its own.
Multifunction Cleaning Base
This section marks the most evident difference between both devices. The Dreame D20 Pro Plus incorporates an auto-empty base with 5-litre bag capacity, which reduces the frequency of bag changes. However, it does not include mop washing or drying functions.
The Roborock Qrevo Curv integrates a complete multifunction base: auto-empty, mop washing with hot water and drying with hot air. The dust bag has a capacity of 2.5 litres, smaller than the Dreame's, but sufficient for several weeks in most homes. The clean and dirty water tanks reach 4 and 3 litres respectively.
The Roborock's 2.0 wash tray self-cleaning keeps the base hygienic without manual intervention. The Dreame, not incorporating a washing system, does not require this function. For those seeking minimal maintenance, the Roborock's base is clearly superior.
Dimensions
The Dreame D20 Pro Plus measures 96.8 mm in height versus the 103 mm of the Roborock Qrevo Curv. This 6.2 mm difference can be decisive for passing under low furniture, sofas or beds with little space. The diameter is practically identical: 350 mm on the Dreame and 352 mm on the Roborock.
The bases present more pronounced differences. The Dreame D20 Pro Plus measures 298 mm wide, 452 mm high and 440 mm deep. The Roborock Qrevo Curv forms an almost perfect cube of 450 mm in all three dimensions. The Dreame's base is more compact in width, facilitating its placement in narrow spaces.
Real-World Experience
For large homes, the Dreame D20 Pro Plus offers clear advantages: greater autonomy, larger dust bag and generous water tank. It can complete extensive cleaning without intervention, although mopping is basic. It is suitable for users who prioritise vacuuming over mopping and prefer simple mop maintenance.
The Roborock Qrevo Curv excels in homes with pets thanks to its superior power, specific animal recognition and anti-tangle brush system. The lifting of the main brush and mops makes it especially versatile in homes with a combination of hard floors and carpets. Mopping with rotating mops, edge extension and automatic washing offers notably superior results.
The Roborock's artificial intelligence reduces manual interventions. It recognises objects, adjusts routes and optimises cleaning without constant supervision. The Dreame requires greater prior attention to remove small obstacles that could block the robot.
In terms of convenience, the Roborock's multifunction base makes the difference. Washing and drying mops automatically eliminates a repetitive manual task. The Dreame requires manually cleaning the mops after each use, which can be inconvenient for those who mop daily.
Conclusion: Which to Choose?
Choose the Dreame D20 Pro Plus if you're looking for a robot with great autonomy for large surfaces, you prioritise vacuuming over mopping and prefer a more moderate investment. Its 5-litre bag and long-lasting battery make it ideal for large homes where manual mop maintenance is not a problem. The lower height facilitates access under low furniture.
Choose the Roborock Qrevo Curv if you need professional-quality mopping with automatic mop washing and drying, you have pets or carpets that require greater suction power, and you value artificial intelligence to minimise interventions. The lifting of brush and mops, together with edge extension, make it the most complete and versatile option. Remote camera access adds extra functionality for home supervision.
