Introduction
We're looking at three high-end robot vacuum cleaners that represent the latest in autonomous cleaning technology. The Dreame L10s Ultra Gen 3 arrives on the market in November 2025 as a balanced proposition, whilst the Roborock Qrevo Edge S5A, launched in 2024, maintains the brand's characteristic reliability philosophy. The Dreame X50 Ultra Blanca, also from 2025, presents itself as the most advanced model in this comparison, incorporating features that place it at the technological pinnacle of the sector.
All three units feature a complete multifunction base, which means they not only empty dust automatically, but also wash and dry the mops after each mopping session. This marks a substantial difference compared to more basic models.
Power and Suction
The Dreame L10s Ultra Gen 3 leads in raw power with its 25,000 Pa of suction, a figure that far exceeds the 18,500 Pa of the Roborock Qrevo Edge S5A and the 20,000 Pa of the X50 Ultra. This difference can be particularly noticeable on long-pile carpets or in homes with pets that shed a lot of hair.
Regarding brushing systems, we find different philosophies. The L10s Ultra Gen 3 mounts a Simple brush, whilst the Qrevo Edge S5A incorporates Roborock's DuoDivide Antienredos system, specifically designed to push hairs towards the centre and prevent tangles. The X50 Ultra opts for a dual HyperStream brush, with two elements anchored at one end that minimise tangles.
All three models integrate an extendable side brush to better reach corners. However, the Roborock includes anti-tangle technology in this side brush, something the X50 Ultra also offers but not the L10s Ultra Gen 3. Dreame's most advanced model goes one step further: it raises both the main brush and the side brush during mopping, preventing them from getting wet and allowing more efficient cleaning in wet mode.
Mopping
All three units use a dual rotating mop system, but with important nuances. Both the L10s Ultra Gen 3 and the X50 Ultra incorporate Roboswing movement, which allows the robot to make a slight swaying motion to get the mops under furniture overhangs or skirting boards. The Qrevo Edge S5A extends its mops without this additional movement.
Mop lift reaches 10.5 mm on both Dreame models, compared to 10 mm on the Roborock. It may seem like a minimal difference, but that extra half millimetre helps to better protect carpets during mixed cleaning mode.
Here appears a decisive advantage of the X50 Ultra: it can automatically remove the mops at the base when you only need to vacuum, without having to do it manually. The other two models require manual intervention for this task.
The Qrevo Edge S5A and the X50 Ultra detect the level of dirt both on the mops and on the floor, automatically adjusting the mopping intensity and mop washing frequency. The L10s Ultra Gen 3 doesn't have this function. All three bases wash the mops with hot water and dry them with hot air, guaranteeing hygiene and absence of bad odours.
Navigation System
The navigation section marks notable differences. The Dreame L10s Ultra Gen 3 mounts a traditional LiDAR turret complemented with a front 3D laser sensor, which allows it to detect low obstacles with precision. The Roborock Qrevo Edge S5A also uses a LiDAR turret, but does without the front 3D sensor, relying on its RR Mason 11.0 algorithm for route planning.
The X50 Ultra represents a qualitative leap: it integrates retractable LiDAR that hides when not needed, reducing the robot's total height. Additionally, it incorporates dual AI camera capable of recognising up to 200 different types of obstacles, compared to the more limited systems of its competitors. It includes a front LED for night vision and allows remote access to the camera from your mobile, a function that can be useful for basic home surveillance.
In specific recognition, the L10s Ultra Gen 3 and the X50 Ultra identify pets, whilst the Qrevo Edge S5A doesn't have this capability. Only the X50 Ultra detects curtains, avoiding getting tangled with them during cleaning.
Autonomy and Battery
Battery capacity clearly differentiates the X50 Ultra, which mounts 6,400 mAh compared to its competitors' 5,200 mAh. However, the actual autonomy of the L10s Ultra Gen 3 reaches 231 minutes, exceeding the 180 minutes of both the Qrevo Edge S5A and the X50 Ultra. This suggests more efficient energy management in Dreame's intermediate model.
For medium or large-sized homes, those extra 51 minutes of the L10s Ultra Gen 3 can make the difference between completing cleaning in a single session or needing an intermediate recharge.
Smart Features
All three models overcome obstacles of 20 mm in height, sufficient to navigate most transitions between floors and small level changes. The X50 Ultra, however, incorporates an advanced wheel system that allows it to overcome single steps of up to 40 mm, doubling the capacity of its competitors. This is especially useful in homes with different levels or isolated steps.
The X50 Ultra includes its own voice assistant, allowing you to give commands directly to the robot without going through your mobile. All three are compatible with Alexa and Google Home for integration into home automation ecosystems.
Multifunction Cleaning Base
The bases of both Dreame models incorporate a detergent tank, dispensing it during mop washing. The Roborock Qrevo Edge S5A doesn't include this option, limiting itself to washing with hot water. Both Dreame models use the third generation of tray self-cleaning, whilst the Roborock mounts version 2.0.
UV disinfection is only present in the X50 Ultra, adding an extra hygienisation step after mop washing. Both Dreame models offer an optional plumbing connection kit, although it's purchased separately and neither comes with it integrated as standard.
In capacities, the L10s Ultra Gen 3 and the X50 Ultra share figures: 3.2-litre dust bag, 4.5-litre clean water tank and 4-litre dirty water tank. The Qrevo Edge S5A falls slightly behind with a 2.7-litre bag, 4 litres of clean water and 3.5 litres of dirty water. These differences mean fewer emptyings and fillings in the Dreame models.
Dimensions
The diameter is practically identical in all three: 350 mm in the Dreame models and 352 mm in the Roborock. Height marks the main difference: the X50 Ultra measures only 89 mm thanks to its retractable LiDAR, allowing it to access under furniture where the other two cannot enter. The L10s Ultra Gen 3 reaches 97 mm and the Qrevo Edge S5A 98 mm.
The bases have similar widths (340 mm), but vary in height and depth. The Qrevo Edge S5A's is lower (521 mm) and deeper (487 mm), whilst the Dreame bases are taller (590 mm) and less deep (approximately 457 mm). It's advisable to measure the available space before deciding.
Real-World Usage Experience
For large homes, the Dreame L10s Ultra Gen 3 offers the greatest actual autonomy with its 231 minutes, sufficient to cover large surfaces without interruptions. Its 25,000 Pa power makes it especially effective on carpets and with pet hair, although its simple brush may require somewhat more maintenance than its competitors' anti-tangle systems.
The Roborock Qrevo Edge S5A stands out for its DuoDivide system, ideal for homes with long-haired pets. The brand's reliability and its RR Mason 11.0 algorithm guarantee precise mapping and efficient routes. The absence of a detergent tank may be a drawback for those seeking the maximum level of hygiene in mopping.
The X50 Ultra represents the most complete and technological option. Its reduced height allows it to clean under practically any furniture, the dual AI camera with remote access adds versatility, and features such as automatic mop removal or UV disinfection elevate the user experience. The ability to overcome steps of up to 40 mm expands its range of action in homes with level changes.
