Introduction
This comparison brings together three high-end proposals with multifunction base: the Dreame L10s Ultra Gen 3, launched in November 2025, the Dreame L40 Ultra from 2024 and the Roborock Qrevo Edge S5A, also from 2024. All three share the design of two rotating mops and LiDAR turret, but differ in key aspects such as power, artificial intelligence and advanced cleaning systems.
The L10s Ultra Gen 3 represents the latest generation from Dreame, whilst the L40 Ultra opts for dual cameras and object recognition. The Qrevo Edge S5A from Roborock offers a balanced approach with its DuoDivide system and intelligent planning. Depending on the type of home, presence of pets or need for remote supervision, each model has its own merits.
Power and Suction
The Dreame L10s Ultra Gen 3 stands out for its power of 25,000 Pa, more than double that of the L40 Ultra and notably superior to the 18,500 Pa of the Roborock Qrevo Edge S5A. This difference is especially relevant on long-pile carpets or in homes with pets that shed a lot of hair.
The brushing system varies between the three models. The L10s Gen 3 features a Simpl brush, designed to reduce tangles. The L40 Ultra is equipped with the TriCut 3.0, which combines bristles with blades to cut hair. The Qrevo Edge S5A opts for the DuoDivide Anti-tangle, which pushes hair towards the central gap to facilitate suction.
Regarding side brushes, all three models include corner extension. However, only the L40 Ultra can lift both the main brush and the side brush during mopping, preventing them from getting wet. The L40 Ultra and the Qrevo Edge S5A feature anti-tangle side brushes, a characteristic absent in the L10s Gen 3.
Mopping
All three robots use two rotating mops with edge extension capability. The L10s Ultra Gen 3 and the L40 Ultra also incorporate the Roboswing system, which performs a lateral movement to introduce the mop under furniture or overhangs. Mop lift reaches 10.5 mm on both Dreame models and 10 mm on the Qrevo Edge S5A, sufficient to avoid thin carpets during mopping.
An important difference appears in automatic mop removal. The L40 Ultra can remove them at the base when only vacuuming is needed, whilst the L10s Gen 3 and the Qrevo Edge S5A require manual intervention. This function is practical in homes with a combination of hard floors and carpets.
Dirt detection marks another dividing line. The L40 Ultra and the Qrevo Edge S5A identify stains on the floor and accumulated dirt on the mops, adjusting mopping accordingly. The L10s Gen 3 lacks these sensors, which limits its adaptation capacity during mopping.
At the base, all three models wash the mops with hot water and dry them with hot air. The L10s Gen 3 boasts third-generation tray self-cleaning, whilst the L40 Ultra and the Qrevo Edge S5A feature second-generation systems. All mop the floor with cold water.
Navigation System
All three units incorporate LiDAR turret for mapping and navigation, along with obstacle avoidance systems. The major difference lies in artificial intelligence and complementary sensors.
The Dreame L40 Ultra integrates dual AI camera with recognition of up to 100 different objects, LED for night vision and remote camera access from the mobile. It can identify pets and detect curtains, adjusting its behaviour accordingly. Its AI Sage 11.0 processor and the CleanGenius system manage cleaning autonomously.
The L10s Ultra Gen 3 features front 3D laser sensor and pet recognition, but does without cameras. It uses CleanGenius for intelligent planning, although without the visual recognition capability of the L40 Ultra.
The Roborock Qrevo Edge S5A lacks camera and 3D laser sensor, relying on its RR Mason 11.0 algorithm and the SmartPlan system to optimise routes. It does not specifically recognise pets or curtains.
Battery Life and Battery
All three robots feature 5,200 mAh batteries, but actual battery life differs. The Dreame L10s Ultra Gen 3 achieves 231 minutes of continuous operation, the L40 Ultra reaches 194 minutes and the Roborock Qrevo Edge S5A stops at 180 minutes.
This difference of more than 50 minutes between Dreame's most recent model and the Roborock can be decisive in large homes. In practice, the L10s Gen 3 has margin to cover larger surfaces without needing intermediate recharging.
Smart Functions
The ability to overcome obstacles varies slightly: 22 mm on the L40 Ultra versus 20 mm on the L10s Gen 3 and the Qrevo Edge S5A. Those additional two millimetres can make the difference on thresholds or thick carpets.
The Dreame L40 Ultra incorporates built-in voice assistant, in addition to compatibility with Alexa and Google Home. The other two models only work with external assistants. This feature allows the L40 Ultra to respond to commands directly without depending on additional smart speakers.
Multifunction Cleaning Base
All three bases perform auto-emptying of the dust container, mop washing with hot water and drying with hot air. The dust bag capacity reaches 3.2 litres in both Dreame models, superior to the 2.7 litres of the Roborock. This translates into fewer bag changes over time.
The water tanks also favour the Dreame models: 4.5 litres of clean water and 4 litres of dirty water, versus 4 and 3.5 litres respectively on the Qrevo Edge S5A. For large homes requiring extensive mopping, this difference can avoid frequent refills.
Only the two Dreame models include detergent tank in the base, dispensing product during mop washing. The Roborock lacks this function. Both Dreame models offer optional plumbing connection kit, which must be purchased separately and allows complete automation of water filling and emptying.
The self-cleaning of the washing tray reaches its third generation in the L10s Gen 3, whilst the L40 Ultra and the Qrevo Edge S5A feature 2.0 versions. This implies greater efficiency in cleaning the base itself, reducing manual maintenance.
Dimensions
All three robots have very similar dimensions. The diameter is around 350 mm on the Dreame models and 352 mm on the Roborock. Height is where differences appear: 97 mm on the L10s Gen 3, 98 mm on the Qrevo Edge S5A and 103.8 mm on the L40 Ultra. Those almost 7 mm extra on the L40 Ultra may limit its access under some low furniture.
The bases maintain similar dimensions in width (340 mm), but vary in height and depth. The Qrevo Edge S5A has the lowest base (521 mm) and the deepest (487 mm). The Dreame models exceed 590 mm in height but are less deep (approximately 457 mm). It's advisable to measure the available space before deciding.
Real-world experience
For large homes, the Dreame L10s Ultra Gen 3 offers the best combination of battery life and power. Its 231 minutes of operation and 25,000 Pa of suction guarantee complete cleaning without interruptions, even in spaces over 200 m². The expanded capacity of the tanks and the 3.2-litre bag reduce maintenance.
In homes with pets, the L40 Ultra provides specific advantages thanks to its dual camera and advanced recognition. It can identify animals and adjust its behaviour, as well as allowing remote supervision. Its TriCut 3.0 brush cuts tangled hair, although the power of 11,000 Pa is barely adequate for abundant hair.
The Roborock Qrevo Edge S5A balances features without excelling in any specific aspect. Its DuoDivide brush works well with hair, the power of 18,500 Pa covers most situations and dirt detection optimises mopping. The absence of detergent tank and smaller bag capacity may require more manual intervention.
For those who prioritise remote supervision or have young children, the L40 Ultra is the only option with real-time camera access and night vision. The built-in voice assistant adds convenience in day-to-day use.
Conclusion: Which to choose?
Choose the Dreame L10s Ultra Gen 3 if you're looking for maximum suction power and leading battery life. It's ideal for large homes, demanding carpets or pets that shed a lot of hair. Its third-generation tray self-cleaning and minimal height facilitate maintenance and access under furniture. The relationship between features and price makes it a very competitive option for 2025.
Choose the Dreame L40 Ultra if you value advanced artificial intelligence, remote camera access and visual object recognition. Its liftable brushes during mopping and the ability to automatically remove mops make it versatile in mixed homes with hard floors and carpets. The built-in voice assistant adds convenience, although suction power falls below its competitors.
Choose the Roborock Qrevo Edge S5A if you prefer an established brand with proven algorithms and are looking for balance without superfluous functions. Its DuoDivide brush, intermediate power and dirt detection cover most scenarios well. The more compact base in height can be advantageous in reduced spaces, although you'll have to do without the detergent tank and accept lower storage capacities.
