Introduction
The Dreame L50 Ultra AE and the Roborock QV 35A represent two very different propositions within the robot vacuum segment with multifunctional base stations. The Dreame model, launched in 2026, opts for high-end features with exceptional suction power of 28,000 Pa, whilst the Roborock QV 35A from 2025 positions itself as a more accessible alternative with 8,000 Pa. Both units integrate a complete multifunctional base with auto-empty, mop washing and drying, although with significant differences in their cleaning capabilities and technologies.
The Dreame unit is designed for users seeking maximum performance in vacuuming and mopping, especially in homes with carpets or pets. The Roborock, on the other hand, is more balanced for dwellings where autonomy and intelligent management take priority over raw power.
Power and Suction
The most striking difference between these robots lies in their suction capacity. The Dreame L50 Ultra AE reaches 28,000 Pa, a figure that more than triples the 8,000 Pa of the Roborock QV 35A. This gap translates into significantly superior performance on carpets and in picking up ingrained dirt or heavy debris such as sand or gravel.
The main brush also marks clear differences. The L50 Ultra AE features the TriCut 3.0 system, which combines bristles with blades to cut long hair and reduce tangles, whilst the QV 35A uses a conventional simple brush. Additionally, the Dreame model can lift its main brush during mopping, preventing it from getting wet or soiling the mops. The Roborock lacks this function.
Regarding the side brush, the Dreame incorporates an extendable design that improves cleaning in corners and edges, something the Roborock doesn't offer. Both models include anti-tangle technology in the side brush, but neither allows it to be lifted during mopping. For homes with pets or long hair, the Dreame system is clearly more practical.
Mopping
Both units use a two rotating mop system, but the Dreame L50 Ultra AE adds advanced functions that notably improve results. Its mop extension with Roboswing movement allows better reach to edges and slightly extends the mops under furniture or overhangs, something the Roborock cannot do.
Mop lifting is similar in both: 10.5 mm in the Dreame and 10 mm in the Roborock. Sufficient to overcome thin carpets without wetting them. However, the L50 Ultra AE can automatically remove the mops at the base when you only want to vacuum, a convenience the QV 35A doesn't offer. With the latter, they must be removed manually if you don't wish to mop.
Neither model includes dirt detection in mops or floor to adjust mopping, nor do they have hot water inside the robot for mopping. Both use cold water during floor mopping.
Navigation System
Both robots employ LiDAR 3.0 turret to map the home with precision. Laser navigation guarantees orderly and efficient paths in both cases. They also feature obstacle avoidance systems, although with different approaches.
The Dreame L50 Ultra AE incorporates a front 3D laser sensor that improves detection of small or low objects. The Roborock QV 35A doesn't have this additional sensor. Neither features a front camera with artificial intelligence, nor specific recognition of pets or curtains, nor remote camera access, nor LED for night vision.
Where the Roborock gains an advantage is in its SmartPlan 1.0 system, an intelligent cleaning function that adapts routes and modes according to home use and needs. The Dreame doesn't include this automatic planning technology. For users who prefer to delegate decisions to the robot, this QV 35A feature is interesting.
Autonomy and Battery
Both robots feature 5,200 mAh batteries, but we only know the autonomy of the Roborock QV 35A: 180 minutes of operation. This figure allows coverage of large homes in a single run, although actual autonomy will depend on cleaning mode and floor type.
The Dreame L50 Ultra AE doesn't specify its autonomy in minutes, but with the same battery capacity and significantly higher suction power, it's foreseeable that its duration will be shorter in intensive modes. In any case, both have a charging base and automatically resume cleaning if they need to recharge mid-task.
Smart Functions
Both robots can overcome obstacles up to 20 mm in height, sufficient to navigate thick cables, door thresholds or small level changes between rooms. Neither includes a robotic arm nor its own voice assistant, but both are compatible with Alexa and Google Home for external voice control.
Multifunctional Cleaning Base
Here the Dreame L50 Ultra AE marks clear differences. Its base washes the mops with hot water, which better eliminates grease and ingrained dirt. The Roborock QV 35A washes with cold water, less effective for difficult stains. Drying also differs: hot air in the Dreame versus cold air in the Roborock. Hot air drying speeds up the process and reduces the risk of bad odours or bacterial growth.
Self-cleaning of the washing tray is another exclusive advantage of the L50 Ultra AE, which incorporates a third-generation system to keep the base hygienic without manual intervention. The Roborock doesn't have this function, which means cleaning the tray periodically by hand.
The Dreame model also integrates a detergent tank in the base, dispensing product during mop washing to improve cleaning. The QV 35A lacks this tank. Additionally, the L50 Ultra AE offers an optional plumbing connection kit that's purchased separately, although neither comes with integrated connection from the factory.
In terms of capacities, the Dreame also comes out ahead. Its dust bag reaches 3.2 litres versus the Roborock's 2.7. The clean water tank is 4.5 litres in the L50 Ultra AE and 4 litres in the QV 35A. The dirty water tank, 4 litres in the Dreame and 3.5 in the Roborock. These differences are noticeable in large homes or with intensive use, reducing maintenance frequency.
Dimensions
The robots are practically identical in size. The Dreame measures 350 mm in diameter and 97 mm in height, whilst the Roborock has 353 mm in diameter and 96.5 mm in height. Half a millimetre less height in the Roborock may slightly facilitate access under certain furniture, although in practice the difference is imperceptible.
The bases, however, do present variations. Both share 340 mm in width, but the Dreame's is taller (590 mm versus 521 mm) and less deep (457 mm versus 487 mm). The L50 Ultra AE base occupies more vertical space due to its larger capacity tanks, whilst the Roborock's is more compact in height but protrudes more forwards. It's advisable to measure the available space before deciding.
Real-World User Experience
The Dreame L50 Ultra AE is designed for demanding homes. Its 28,000 Pa power makes it ideal for thick carpets, homes with pets or dwellings where much dirt accumulates. The TriCut 3.0 brush and extendable side brush reinforce this deep cleaning vocation. The base with hot water and air washing and drying, tray self-cleaning and detergent tank minimise maintenance and guarantee more hygienic mopping.
The Roborock QV 35A is better suited to users who value the 180-minute autonomy and intelligent SmartPlan 1.0 management. Its 8,000 Pa power is sufficient for hard floors and thin carpets, although it will fall short on long-pile carpets or situations of intense dirt. The more compact base in height may be advantageous in confined spaces, but requires more manual attention as it lacks tray self-cleaning and hot water washing.
In large homes, the Dreame offers greater base tank capacities, reducing emptying and refilling. For homes with many corners or furniture against walls, the mop extension and extendable side brush of the L50 Ultra AE make a real difference. The Roborock, with its SmartPlan system, is more convenient for those who prefer the robot to decide routes and modes without manual configuration.
Conclusion: Which to Choose?
Choose the Dreame L50 Ultra AE if you're seeking maximum performance in vacuuming and mopping, have demanding carpets or pets, value minimal maintenance with a latest-generation base and don't mind investing more in high-end features. Its 28,000 Pa power, liftable TriCut 3.0 brush, Roboswing mop extension, hot water and air washing and drying, tray self-cleaning and detergent tank make it a very complete option for large homes or with intensive cleaning needs.
Choose the Roborock QV 35A if you prioritise the 180-minute autonomy, prefer an intelligent cleaning system that plans automatically with SmartPlan 1.0, are looking for a more compact base in height or your budget is tighter. Its 8,000 Pa power is adequate for hard floors and thin carpets, and Roborock's reliability as a world-leading brand guarantees a solid experience, although without the advanced mopping and maintenance functions of the Dreame.
For homes with pets or long hair, the Dreame is more practical. If you live in a small or medium-sized flat without thick carpets and value autonomous management, the Roborock perfectly covers your needs. The price difference usually reflects these features: the L50 Ultra AE is an investment in latest-generation technology, whilst the QV 35A offers a reasonable balance between functions and cost.
