Introduction
Choosing between the Dreame L40s Pro Ultra, the Roborock Qrevo Curv S5X and the Mova V50 Ultra requires analysing three high-end proposals with different approaches. The Dreame L40s Pro Ultra arrives in 2025 with a balance between power and advanced features, whilst the Roborock Qrevo Curv S5X from 2024 relies on the proven reliability of the world's leading brand. The Mova V50 Ultra, also from 2025, surprises with superior technical specifications in several key areas.
All three models integrate a complete multifunction base, laser navigation and mopping systems with rotating mops. However, differences in suction power, battery, intelligent navigation and robot height define clearly differentiated usage profiles.
Power and Suction
Suction power shows notable differences. The Mova V50 Ultra leads with 24,000 Pa, a figure that widely exceeds the 19,000 Pa of the Dreame L40s Pro Ultra and the 18,500 Pa of the Roborock Qrevo Curv S5X. This advantage translates into better capability for thick carpets and ingrained dirt.
Regarding brushes, the Dreame L40s Pro Ultra and the Mova V50 Ultra mount the HyperStream anti-tangle dual brush system, specifically designed to prevent long hair from wrapping around. The Roborock uses the DuoDivide anti-tangle brush, with a design that pushes hair towards the central suction gap. All three systems are effective against tangles, albeit with different mechanics.
The extendable side brush appears on all three models, improving corner cleaning. However, both the Dreame and the Mova can lift the main brush and side brush during mopping, preventing them from getting unnecessarily wet. The Roborock Qrevo Curv S5X does not have this function, which may affect long-term maintenance of the main brush when mopping frequently.
Mopping
All three robots employ two rotating mops with edge extension. The Dreame L40s Pro Ultra and the Mova V50 Ultra additionally incorporate the Roboswing system, which allows the robot to perform lateral movements to introduce the mop under furniture and overhangs. The Roborock offers mop extension but without that additional movement.
Mop lift reaches 10.5 mm on the Dreame and the Mova, compared to 10 mm on the Roborock. Minimal differences that are not decisive in daily practice.
Where the Mova V50 Ultra sets itself apart is in mopping with hot water on the floor. Both the Dreame and the Roborock mop with cold water. Hot water improves the dissolution of grease and adhered dirt, especially in kitchens.
Mop washing in the base is carried out with hot water on all three models, and drying also uses hot air. The Dreame L40s Pro Ultra and the Mova V50 Ultra integrate third-generation tray self-cleaning, whilst the Roborock mounts version 2.0. Both Dreame and Mova models can automatically remove the mops at the base to perform vacuuming only; the Roborock does not offer this option.
All three detect dirt both on the mops and on the floor to adjust mopping, scrubbing areas that need it.
Navigation System
The Roborock Qrevo Curv S5X mounts a traditional LiDAR turret with obstacle avoidance, but without AI camera or front 3D laser sensor. It operates with the RR Mason 11.0 algorithm, which offers precise mapping and efficient planning.
The Dreame L40s Pro Ultra incorporates a LiDAR turret combined with dual AI camera and front 3D laser sensor. It recognises up to 180 different types of obstacles, including pets and curtains, adjusting cleaning according to the environment. It features LED for night vision and allows remote access to the camera from the app.
The Mova V50 Ultra uses retractable LiDAR with dual AI camera and 3D laser sensor. It surpasses the Dreame in object recognition, identifying up to 200 types of obstacles. It also includes pet detection, curtains, night LED and remote camera access.
This difference is relevant for homes with pets, young children or multiple obstacles on the floor. The Roborock focuses on efficient navigation via laser, whilst Dreame and Mova add layers of visual intelligence.
Autonomy and Battery
The Mova V50 Ultra stands out with a 6,400 mAh battery that provides 220 minutes of autonomy. The Dreame L40s Pro Ultra mounts 5,200 mAh with identical 220 minutes of operation, optimising energy consumption better. The Roborock Qrevo Curv S5X also equips 5,200 mAh but offers 180 minutes of autonomy.
In large homes, those additional 40 minutes from the Dreame and the Mova can make the difference between completing cleaning in a single run or requiring intermediate recharging.
Smart Features
The ability to overcome obstacles varies significantly. The Roborock Qrevo Curv S5X can negotiate steps of up to 20 mm. The Dreame L40s Pro Ultra and the Mova V50 Ultra use a simple step system that allows them to overcome obstacles, although the table does not specify the exact height.
The Dreame L40s Pro Ultra and the Mova V50 Ultra integrate their own voice assistant, allowing commands to be given directly to the robot without intermediaries. All three models are compatible with Alexa and Google Home.
Multifunction Cleaning Base
All three bases perform auto-emptying, washing with hot water and drying with hot air of the mops. The Dreame L40s Pro Ultra and the Mova V50 Ultra feature a 3.2-litre dust bag, larger than the Roborock's 2.5 litres. This means less frequent bag changes.
In clean water tanks, the Dreame leads with 4.5 litres, followed by the Roborock with 4 litres and the Mova with 4 litres as well. For dirty water, the Dreame offers 4 litres, the Mova 3.5 litres and the Roborock 3 litres.
The Dreame L40s Pro Ultra includes a single detergent tank, whilst the Mova V50 Ultra mounts a dual detergent tank for different types of flooring or uses. The Roborock Qrevo Curv S5X does not incorporate a detergent tank in the base. Additionally, only the Mova integrates UV disinfection in the base.
The Dreame offers an optional plumbing connection kit that is purchased separately, automating water filling and emptying. Neither the Roborock nor the Mova offer this possibility.
Dimensions
Robot height is critical for accessing under furniture. The Mova V50 Ultra measures only 89.5 mm, making it the lowest of the three. The Roborock Qrevo Curv S5X reaches 98 mm, whilst the Dreame L40s Pro Ultra extends to 103.8 mm. Those nearly 15 mm difference between the Mova and the Dreame can determine whether the robot accesses or not under sofas, beds or low cabinets.
Diameter barely varies: 350 mm on Dreame and Mova, 352 mm on the Roborock. Imperceptible differences in practice.
The bases present different designs. The Roborock's measures 450 x 450 x 450 mm, an almost cubic format. The Dreame's occupies 340 mm width, 590.5 mm height and 456.7 mm depth, narrower but also taller. The Mova sits in the middle ground with 420 x 470 x 458 mm. It's advisable to measure available space before deciding.
Real-World Usage Experience
For large homes, the Mova V50 Ultra combines the largest battery with excellent autonomy and superior suction power. Its reduced height allows it to access where others cannot reach, and hot water for mopping the floor provides an extra cleaning boost.
In homes with pets, both the Dreame L40s Pro Ultra and the Mova V50 Ultra offer specific animal recognition and effective anti-tangle brushes. The Roborock, although without pet recognition, also mounts an anti-tangle brush and offers proven reliability.
If seeking total autonomy with minimal maintenance, the Mova stands out with dual detergent tank, UV disinfection and the largest battery capacity. The Dreame provides flexibility with the optional plumbing connection kit.
For those prioritising advanced visual navigation and remote camera access, the Mova leads with 200 recognised obstacles, followed by the Dreame with 180. The Roborock dispenses with camera but compensates with the proven effectiveness of the RR Mason 11.0 algorithm.
