Introduction
The Dreame L50 Ultra AE and the Roborock Qrevo S5V represent two advanced propositions within the robot vacuum segment with multifunctional base stations. The Dreame model, launched in March 2026, opts for superior suction power and more comprehensive cleaning functions in its base. The Qrevo S5V from Roborock, from 2025, positions itself as a more balanced alternative that incorporates artificial intelligence in its cleaning planning.
Both units are designed for users seeking to fully automate home maintenance, with the ability to vacuum and mop with minimal manual intervention. The choice between one or the other will depend on specific priorities: maximum power and base autonomy versus intelligent navigation and compactness.
Power and Suction
The most evident difference between these robot vacuums lies in suction power. The Dreame L50 Ultra AE reaches 28,000 Pa, more than double the 12,000 Pa of the Roborock Qrevo S5V. This difference translates into greater capacity to extract embedded dirt from carpets and to pick up fine particles in a single pass.
Regarding the brushing system, the L50 Ultra AE features a TriCut 3.0 brush, which combines bristles with blades to cut tangled hair. The Qrevo S5V uses the DuoDivide Antienredos system, which pushes hair towards the central gap to facilitate suction. Both technologies are designed to reduce manual maintenance, albeit with different approaches.
The Dreame's main brush can lift during mopping, something the Roborock model doesn't incorporate. This function prevents the brush from wetting carpets or getting unnecessarily dirty when the robot is only mopping. The side brush also shows differences: the L50 Ultra AE's is extendable to better reach corners, whilst the S5V's maintains a fixed configuration. Both feature anti-tangle technology on the side brush.
Mopping
Both models employ dual rotating mop systems for mopping, a configuration that guarantees superior results to static mops. The Dreame L50 Ultra AE adds the Roboswing system, which allows the robot to perform a swinging movement to introduce the mop under furniture and overhangs. The Qrevo S5V also features mop extension for edges, though without that additional movement.
Mop lifting is practically identical: 10.5 mm on the Dreame versus 10 mm on the Roborock. Sufficient to pass over medium-thickness carpets without wetting them. Where a relevant difference does appear is in automatic removal: the L50 Ultra AE can remove the mops at the base when it only needs to vacuum, whilst the S5V requires doing this manually.
Neither robot includes dirt detection for automatic rewashing or rescrubbing, nor do they use hot water to mop the floor. Both work with cold water in the robot's tank.
Navigation System
Both the Dreame L50 Ultra AE and the Roborock Qrevo S5V use 3D LiDAR turrets to map the home and navigate with precision. Both feature obstacle avoidance, but the Dreame adds a front 3D laser sensor that improves detection of small objects at floor level.
The Qrevo S5V incorporates SmartPlan 1.0, an intelligent AI-powered cleaning system that adapts routes and modes according to floor type and home layout. The L50 Ultra AE doesn't include this function. Neither model has a front camera, pet recognition, curtain detection, LED for night vision, or remote camera access.
In practice, the Dreame's 3D laser sensor can make a difference in homes with many small objects on the floor, whilst the Roborock's artificial intelligence proves useful for optimising cleaning without having to manually configure each zone.
Autonomy and Battery
Both robots feature 5,200 mAh batteries. The Roborock Qrevo S5V specifies an autonomy of 180 minutes, data that isn't available for the Dreame L50 Ultra AE. This autonomy is sufficient to cover medium-to-large homes in a single cleaning session.
Full charging time isn't specified for either model, nor is the maximum recommended surface area. Typically, robots with this battery capacity cover between 200 and 250 square metres without problems.
Smart Functions
The ability to overcome thresholds is identical in both: 20 mm. This allows navigating transitions between rooms, door frames, and small level changes without getting stuck. Neither model incorporates a robotic arm or its own voice assistant, though they are compatible with external assistants such as Alexa or Google Home.
Multifunctional Cleaning Base
Significant differences appear here. Both bases feature auto-emptying of the dust bin, washing and drying of mops with hot air. However, the Dreame L50 Ultra AE washes the mops with hot water, whilst the Roborock Qrevo S5V uses cold water. Hot water improves the removal of grease and adhered dirt on the mops.
The L50 Ultra AE incorporates third-generation self-cleaning in the washing tray, a function absent on the S5V. This considerably reduces manual maintenance of the base. It also includes a detergent tank, which dispenses product during mop washing to improve hygiene. The Roborock model lacks this option.
In terms of capacities, the Dreame offers a 3.2-litre dust bag versus 2.7 litres on the Roborock. The clean water tanks are 4.5 litres and 4 litres respectively; the dirty water tanks, 4 litres and 3.5 litres. These differences allow the L50 Ultra AE to operate longer without intervention.
The Dreame has an optional kit for connection to plumbing, which is purchased separately. Neither includes this connection integrated from the factory nor UV disinfection.
Dimensions
The Roborock Qrevo S5V is slightly more compact in height: 96.5 mm versus 97 mm for the Dreame L50 Ultra AE. A minimal difference that in practice barely influences the ability to pass under furniture. The diameter is also very similar: 353 mm on the Roborock and 350 mm on the Dreame.
The bases show more notable differences. The L50 Ultra AE's measures 590 mm in height versus 521 mm for the S5V, though it's less deep: 457 mm versus 487 mm. Both have the same width of 340 mm. These measurements are worth considering if available space for the base is limited.
The robot's internal tanks also vary: the Dreame carries 250 ml of dust and 80 ml of water; the Roborock, 330 ml of dust and 80 ml of water. The S5V's larger dust tank can be advantageous in homes with lots of dry dirt, though as both feature auto-emptying, the difference loses relevance.
Real-World Usage Experience
For large homes, the Dreame L50 Ultra AE offers clear advantages: greater capacity in the base's tanks, hot water for washing mops, and tray self-cleaning reduce maintenance tasks to a minimum. The 28,000 Pa power proves especially useful if there are thick carpets or pets that shed lots of hair.
The Roborock Qrevo S5V excels in homes where artificial intelligence is valued for optimising routes and cleaning modes without manual configuration. Its more compact base in height facilitates installation in reduced spaces. Navigation is equally precise, though it lacks the additional front 3D laser sensor.
The mopping system works well in both cases on hard floors and parquet. The Dreame adds advantages such as automatic mop removal and the Roboswing movement to better reach under furniture. In homes with pets, the L50 Ultra AE's main brush lifting during mopping prevents it from getting unnecessarily dirty.
Compatibility with external voice assistants facilitates voice command control on both models. Neither requires constant supervision thanks to the multifunctional bases, which manage emptying, washing, and drying autonomously.
Conclusion: Which to Choose?
Choose the Dreame L50 Ultra AE if: you're seeking maximum suction power and want to forget about maintenance. Its base with hot water for washing mops, third-generation tray self-cleaning, detergent tank, and greater capacities make it the most autonomous option. Ideal for large homes, with thick carpets or pets. The extendable side brush and main brush lifting during mopping are details that make a difference in corner cleaning and care of the brushing system.
Choose the Roborock Qrevo S5V if: you prefer a robot with artificial intelligence that automatically optimises cleaning through SmartPlan 1.0. Its more compact base in height facilitates installation in reduced spaces. The larger dust tank in the robot can prove useful if you prefer to empty manually less frequently between sessions. It's a balanced option for those who value Roborock's reliability and don't need maximum suction power or the advanced functions of the Dreame's base.
