Introduction
The Roborock Qrevo Curv 2 Pro and the Dreame X50 Ultra Blanca represent two flagship models launched in 2025, both positioned at the premium end of the market. These aren't entry-level devices but rather comprehensive cleaning solutions designed for users who want minimal intervention in their daily floor maintenance. Each comes with a multifunctional base that handles mop washing with hot water and drying with heated air, which makes a real difference to the quality of mopping results.
The Roborock model carries the reputation of a brand widely regarded as the global leader in robotic vacuum cleaners, whilst Dreame continues to challenge established players with competitive specifications at attractive price points. Both robots feature dual rotating mops, advanced AI navigation with dual cameras, and the ability to recognise up to 200 different obstacles. They're built for homes where thorough cleaning matters, particularly those with a mix of hard floors and carpets, and where pets might leave fur scattered about.

Power and Suction
Suction power sits at 25,000 Pa for the Roborock Qrevo Curv 2 Pro, which puts it ahead of the Dreame X50 Ultra Blanca's 20,000 Pa. That 5,000 Pa difference isn't just a number on paper—it translates into better performance on carpets and when dealing with embedded dirt or pet hair. For households with rugs or high-pile flooring, this extra grunt can make weekly deep cleans more effective.
The approach to brush design diverges here. Roborock uses its DuoDivide anti-tangle system, which channels hair towards the centre suction point to reduce tangling. Dreame counters with a dual HyperStream brush setup, also engineered to minimise hair wrapping. Both systems aim to solve the same problem, just through different mechanical solutions. In practice, either should handle homes with long hair or shedding pets without constant manual intervention.
Both robots lift their main brush when mopping, preventing the transfer of dirt from the brush onto freshly cleaned floors. The side brush can extend on both models to reach into corners more effectively, and both feature anti-tangle technology on the side brush as well. However, the Dreame X50 Ultra Blanca goes a step further by lifting its side brush during mopping, which prevents it from flicking water or interfering with the mop pads. The Roborock doesn't include this feature.
Mopping
Both models use dual rotating mops, which spin to scrub floors rather than just dragging a damp cloth across the surface. The Roborock Qrevo Curv 2 Pro extends its mops to reach edges and skirting boards, whilst the Dreame X50 Ultra Blanca does the same but adds RoboSwing—a movement that allows the robot to angle slightly and push the mop further under furniture edges and overhangs.
Mop lift height varies between the two. The Roborock offers a range of 7-17 mm, which gives it flexibility depending on carpet thickness. The Dreame lifts to 10.5 mm, which is still sufficient for most short-pile rugs but doesn't match the maximum clearance of the Roborock. For homes with thick carpets or rugs, that extra lift can prevent damp mops from touching fabric when the robot transitions between floor types.
Both bases wash the mops with hot water and dry them using heated air, which helps eliminate odours and bacteria. The bases also support automatic mop removal, meaning the robot can detach its mops at the base and operate in vacuum-only mode. Dirt detection works on both models, triggering additional cleaning passes when the sensors identify particularly soiled areas or dirty mop pads.
Navigation System
Navigation relies on retractable LiDAR in both cases, combined with dual AI cameras and 3D laser sensors at the front. This setup allows both robots to map spaces accurately, avoid obstacles dynamically, and recognise specific objects—200 different types, to be precise. Pet recognition is included, so the robots can identify and navigate around animals or their belongings.
The Dreame X50 Ultra Blanca adds curtain detection, which helps the robot avoid getting tangled in drapes or fabric that hangs low. The Roborock Qrevo Curv 2 Pro doesn't list this feature. Both models include LED lighting for night vision, which improves navigation in dim conditions, and both offer remote camera access through their respective apps.
AI-driven cleaning strategies differ slightly in branding. Roborock uses SmartPlan 3.0, whilst Dreame employs CleanGenius with its AI Sage 13.0 octa-core processor. Both systems analyse room layouts, adjust suction and water flow, and prioritise high-traffic areas. The practical outcome is similar: smarter cleaning with less manual scheduling required.
Battery and Autonomy
Battery capacity is identical at 6,400 mAh, but runtime tells a different story. The Roborock Qrevo Curv 2 Pro runs for 290 minutes, whilst the Dreame X50 Ultra Blanca manages 180 minutes. That's over an hour and a half of extra cleaning time, which matters in larger homes or when covering multiple floors without returning to the base.
For homes exceeding 150 square metres, the extended runtime of the Roborock becomes a genuine advantage. The Dreame's 180 minutes is still respectable and sufficient for most standard-sized properties, but the Roborock's stamina means fewer interruptions and faster completion of full-home cleans.
Smart Functions
Both robots can climb obstacles up to 4 cm, which allows them to transition between rooms with different floor levels or navigate over door thresholds without getting stuck. This is particularly useful in homes with uneven flooring or where carpets sit on raised platforms.
Each model includes its own voice assistant, allowing basic voice commands without relying on external smart home ecosystems. Both also integrate with Alexa and Google Home for those who prefer using established platforms.
Multifunctional Cleaning Base
The bases handle auto-emptying, mop washing, and mop drying, but there are notable differences. The Dreame X50 Ultra Blanca includes UV disinfection, which sanitises the water and internal components to reduce bacterial growth. The Roborock doesn't offer this. The Dreame also features a detergent dispenser, automatically adding cleaning solution during mop washes. The Roborock lacks this feature, relying on plain hot water instead.
Self-cleaning of the washing tray is present on both—third-generation systems that rinse and scrub the tray after each mop wash. The Dreame includes an optional kit for plumbing connection, which can be purchased separately to automate water refilling and drainage. The Roborock doesn't offer this option.
Dust bag capacity is 2.5 litres on the Roborock versus 3.2 litres on the Dreame. Clean water tanks measure 4 litres and 4.5 litres respectively, whilst dirty water tanks are 3 litres and 4 litres. The Dreame's larger capacities mean less frequent maintenance, which can be helpful in busy households or for those who prefer longer intervals between servicing.
Dimensions
The Roborock Qrevo Curv 2 Pro measures 79.8 mm in height, making it noticeably lower than the Dreame X50 Ultra Blanca at 89 mm. That 9 mm difference can determine whether the robot fits under sofas, beds, or kitchen cabinets. If your furniture sits low to the ground, the Roborock has a clear advantage.
Diameter is virtually identical—352 mm versus 350 mm—so neither has an edge in navigating tight spaces. Base dimensions differ considerably. The Roborock's base forms a 450 mm cube, whilst the Dreame's base is narrower at 340 mm wide but taller at 590.5 mm and slightly deeper at 456.7 mm. The Roborock's base occupies more floor space but sits lower, whilst the Dreame's base has a smaller footprint but stands taller. Your available floor space and storage preferences will dictate which configuration suits better.
Real-World Use Experience
For larger homes, the Roborock Qrevo Curv 2 Pro's extended battery life and higher suction make it the more capable option. The 290-minute runtime allows it to cover expansive areas without needing to recharge mid-clean, and the 25,000 Pa suction ensures carpets and rugs receive thorough treatment. The lower profile also means it can access more areas under furniture, reducing the number of spots you'll need to clean manually.
The Dreame X50 Ultra Blanca suits those who value convenience features like UV disinfection and automatic detergent dispensing. The larger dust bag and water tanks reduce maintenance frequency, and the optional plumbing kit can eliminate manual refilling altogether if you're willing to invest in the add-on. The RoboSwing function helps with edge cleaning in homes with complex furniture arrangements or lots of skirting detail.
Pet owners will find both models capable, thanks to anti-tangle brushes and strong suction. The Roborock's extra power gives it a slight edge with embedded fur, whilst the Dreame's larger dust capacity means fewer trips to empty the bag during heavy shedding seasons.
Maintenance demands are similar, though the Dreame's detergent dispenser and UV disinfection add steps to the cleaning process if you choose to use them. The Roborock's simpler base design might appeal to those who prefer straightforward operation without extra features to manage.
Conclusion: Which One to Choose?
Choose the Roborock Qrevo Curv 2 Pro if: you have a large home requiring extended runtime, need maximum suction for deep carpet cleaning, want a robot that fits under low furniture, or prefer a brand with a strong reputation for reliability and app performance. It's the better choice for pet owners dealing with heavy shedding and for those who prioritise cleaning power over convenience features.
Choose the Dreame X50 Ultra Blanca if: you want UV disinfection and automatic detergent dispensing, prefer larger dust and water capacities for less frequent maintenance, value the optional plumbing connection for fully automated water management, or need curtain detection in your navigation setup.
