Introduction
In this comparison, we analyse two high-end robot vacuum cleaners recently launched on the market: the Dreame L40s Pro Ultra (2025) and the Roborock Qrevo Edge S5A (2024). Both models represent the latest in intelligent home cleaning technology, offering powerful suction systems, advanced mopping and artificial intelligence navigation. If you're looking for a premium robot vacuum cleaner that combines vacuuming and mopping with minimal manual intervention, this comparison between the Dreame robot vacuum cleaner and the Roborock robot vacuum cleaner will help you decide which one best suits your needs.
The Dreame L40s Pro Ultra arrives in 2025 with significant technological improvements, whilst the Roborock Qrevo Edge S5A, launched in 2024, has already proven to be a solid competitor in the premium segment. Both include multifunctional cleaning bases and advanced features that minimise maintenance, but present important differences in power, autonomy and navigation capabilities that may tip the balance depending on your home and priorities.
Power and Suction
In terms of suction power, the Dreame L40s Pro Ultra leads this robot vacuum cleaner comparison with 19000 Pa thanks to its Turbo Force 6 technology, surpassing the 18500 Pa of the Roborock Qrevo Edge S5A. This difference of 500 Pa may seem marginal, but it's relevant on high-pile carpets or when there's ingrained dirt, where each additional pascal improves the final result.
Both models incorporate anti-tangle main brush systems, an essential feature for homes with pets or people with long hair. The Dreame L40s Pro Ultra is equipped with a Doble Cepillo Antienredo de Pelos, whilst the Roborock Qrevo Edge S5A uses the DuoDivide Antienredos de Pelos system. These technologies significantly reduce manual maintenance by preventing hair from wrapping around the main roller, a common problem in more basic models.
Mopping
Although specific data on extended mopping systems, mop lifting or RoboSwing technology are not available for these particular models, both robots integrate mopping functions as a complement to vacuuming. The water tank capacity is identical in both cases: 80 ml, sufficient for mopping sessions in medium-sized homes without the need for constant refilling.
It's important to note that both have cleaning bases that automate mop maintenance, reducing manual intervention. The Dreame L40s Pro Ultra incorporates 3rd generation washing tray self-cleaning, whilst the Roborock Qrevo Edge S5A uses the 2.0 watertight system, both designed to maintain the hygiene of mopping components between sessions.
Navigation System
Intelligent navigation is an aspect where the Dreame L40s Pro Ultra shows clear advantages. This Dreame robot vacuum cleaner incorporates AI intelligent cleaning through its CleanGenius 2.0 system, which also includes stain recognition with artificial intelligence. This function allows the robot to identify particularly dirty areas and automatically apply greater cleaning intensity, optimising the result without user intervention.
For its part, the Roborock Qrevo Edge S5A also features intelligent cleaning through SmartPlan 2.0, but lacks AI stain recognition. This means that, although it plans efficient routes and correctly maps the home, it doesn't automatically adjust intensity according to the level of dirt visually detected. For users who prioritise total automation, this difference may be decisive when choosing which robot vacuum cleaner to buy.
Autonomy and Battery
Both robots are equipped with 5200 mAh batteries, but performance differs notably. The Dreame L40s Pro Ultra offers an autonomy of 220 minutes, exceeding the 180 minutes of the Roborock Qrevo Edge S5A. This difference of 40 additional minutes represents approximately 22% more continuous operating time.
In practice, this greater autonomy of the Dreame robot vacuum cleaner translates into the ability to clean larger homes in a single session without returning to the base to recharge. For flats over 150 square metres or multi-storey houses, these extra minutes can make the difference between completing the cleaning in one go or needing multiple cycles.
Smart Functions
In obstacle-crossing capability, the Dreame L40s Pro Ultra stands out with its extra wheels 1.0 system that allows it to overcome height differences between 22 and 40 mm. This range is especially useful in homes with thick carpets, raised door thresholds or small steps between rooms.
The Roborock Qrevo Edge S5A can overcome obstacles up to 20 mm, a respectable capability that covers most typical domestic situations such as medium-thickness carpets and standard transitions between floors. However, in homes with more pronounced architectural barriers, the Dreame offers greater versatility.
Neither model incorporates a robotic arm, a technology that some ultra-premium range competitors are beginning to integrate for additional tasks such as moving small objects.
Multifunctional Cleaning Base
Both robots include multifunctional cleaning bases that automate much of the maintenance. In terms of dust storage capacity, the Roborock Qrevo Edge S5A has a slight advantage with 325 ml compared to the 300 ml of the Dreame L40s Pro Ultra. This difference of 25 ml is minimal in daily use and both require similar periodic emptying.
An important differentiating feature is the self-cleaning of the washing tray. The Dreame L40s Pro Ultra incorporates the third generation of this system, representing the most recent evolution in automated maintenance of mopping components. The Roborock Qrevo Edge S5A uses the 2.0 watertight system, also effective but from a previous generation. These technologies prevent the accumulation of dirt and bad odours in the base itself, a common problem in models without this function.
Dimensions
The dimensions are practically identical between both models. The Dreame L40s Pro Ultra measures 350 mm in diameter and 103.8 mm in height, whilst the Roborock Qrevo Edge S5A has 352 mm in diameter and 98 mm in height. The difference of 2 mm in diameter is insignificant, but the 5.8 mm less in height of the Roborock may be relevant for accessing under very low furniture such as some sofas or beds with little separation from the floor.
If your home has furniture with reduced spaces underneath, those additional millimetres of the Roborock robot vacuum cleaner may allow it to clean areas inaccessible to the Dreame. Conversely, if height is not a limiting factor in your home, both will navigate without problems under most standard furniture.
Conclusion: Which One to Choose?
After analysing the differences between the Dreame L40s Pro Ultra and the Roborock Qrevo Edge S5A, both position themselves as excellent options in the best robot vacuum cleaner 2025, but with differentiated profiles.
Choose the Dreame L40s Pro Ultra if you're looking for:
- The highest available suction power (19000 Pa) for demanding carpets or pets
- Maximum autonomy (220 minutes) for large homes or complete cleaning without interruptions
- Intelligent stain recognition with AI for total automation
- Greater obstacle-crossing capability (up to 40 mm) in homes with pronounced height differences
- The latest technology in tray self-cleaning (3rd generation)
The Roborock Qrevo Edge S5A is ideal for:
- Users who prioritise a lower profile (98 mm) to access under low furniture
- Those looking for an established 2024 model with excellent performance-price ratio
- Homes with standard obstacles (up to 20 mm) without extreme height differences
- Users satisfied with intelligent planning without the need for AI stain recognition
In this comparison between robot vacuum cleaners, the Dreame L40s Pro Ultra positions itself as the most technologically advanced option, especially for its AI stain recognition, greater autonomy and obstacle-crossing capability. The Roborock Qrevo Edge S5A, on the other hand, offers excellent performance with a lower profile and very competitive features at a possibly more competitive price as it's from the previous year. The final decision will depend on whether you prioritise the latest technology and maximum autonomy (Dreame) or a solid balance with better access under low furniture (Roborock).
