Introduction
Dreame presents three interesting proposals within its 2025 catalogue that deserve detailed analysis. The Dreame Aqua 10 Ultra Roller opts for a mopping system with a rotating roller, a technology different from what's usual in the market. The Dreame L10s Ultra Gen 3, launched in November 2025, represents the evolution of the third generation of the L10s series with improvements in autonomy and base washing system. Finally, the Dreame L40s Pro Ultra positions itself as a complete device with dual camera and advanced detection functions.
Each of these models is designed for different profiles. The Aqua 10 Ultra Roller stands out for its raw power and differential mopping system. The L10s Ultra Gen 3 seeks to offer greater autonomy with a more balanced configuration. The L40s Pro Ultra adds intelligent capabilities that can be decisive for those seeking total automation.
Power and Suction
Suction power marks notable differences between these three devices. The Dreame Aqua 10 Ultra Roller leads with 30,000 Pa, a figure that widely exceeds the 25,000 Pa of the L10s Ultra Gen 3 and the 19,000 Pa of the L40s Pro Ultra. This difference is especially noticeable on carpets and when there's accumulation of persistent dirt.
Regarding the brushing system, the Aqua 10 and the L40s Pro share a dual main brush, a design that improves the collection of hair and large particles. The L10s Ultra Gen 3 has a single brush, which may result in somewhat less efficient cleaning on complicated surfaces.
The extendable side brush is present in all three models, facilitating cleaning in corners. However, only the Aqua 10 and the L40s Pro raise both the main brush and the side brush during mopping, preventing them from getting unnecessarily wet. The L10s Ultra Gen 3 lacks these elevations, which may affect the mopping result in some situations. Additionally, the side brush of the L10s doesn't incorporate an anti-tangle system, something that the other two models do offer.
Mopping
Here we find the most significant difference between these robots. The Dreame Aqua 10 Ultra Roller uses a rotating roller with 12N of pressure, a system that more closely resembles a traditional mop and that proves effective for stuck-on stains. The other two models use rotating mops, a more widespread solution in the market.
All three devices have mop extension to better reach edges. The L10s Ultra Gen 3 and the L40s Pro Ultra also incorporate Roboswing movement, which allows the robot to make a slight turn to get the mop under furniture or protrusions. The Aqua 10, with its roller system, doesn't need this movement.
Mop elevation varies: the Aqua 10 Ultra Roller reaches 14 mm plus the roller itself which retracts, whilst the other two remain at 10.5 mm. This difference may be relevant for medium-pile carpets.
Mop washing is carried out with hot water in the Aqua 10 and in the L40s Pro, whilst the L10s Ultra Gen 3 also washes with hot water. Hot air drying is confirmed in the L10s Ultra Gen 3 and the L40s Pro Ultra; in the Aqua 10 the drying temperature is not specified in the available data.
Only the L40s Pro Ultra allows automatic removal of mops at the base, a practical function when you only want to vacuum without mopping. Dirt detection both on the mops and on the floor is present in the Aqua 10 and in the L40s Pro, but not in the L10s Ultra Gen 3.
Navigation System
The navigation system shows important differences. The Aqua 10 Ultra Roller incorporates a retractable LiDAR, a design that reduces the total height of the robot. The L10s Ultra Gen 3 and the L40s Pro Ultra have a traditional LiDAR turret.
The biggest difference lies in the cameras. The Aqua 10 Ultra Roller and the L40s Pro Ultra are equipped with dual RGB camera, allowing them to recognise up to 240 and 180 obstacles respectively. The L10s Ultra Gen 3 lacks a camera, which limits its object recognition capabilities.
All three models incorporate a front 3D laser sensor and pet recognition. However, curtain detection is only present in the Aqua 10 and the L40s Pro. Remote camera access and the night vision LED are also exclusive to these two models with camera.
The Aqua 10 stands out with the AI Sage 15.0 processor, whilst in the other two the specific chip is not specified. AI stain recognition works in the Aqua 10 and the L40s Pro, but not in the L10s Ultra Gen 3.
Autonomy and Battery
The Dreame Aqua 10 Ultra Roller has a 6,400 mAh battery, superior to the 5,200 mAh of the other two models. However, the greater suction power consumes more energy, resulting in 160 minutes of autonomy.
The L10s Ultra Gen 3 reaches 231 minutes, the highest figure of the three. This makes it the best option for large homes where prolonged cleaning sessions are needed. The L40s Pro Ultra sits at 220 minutes, also a very competent figure.
In practice, the L10s Ultra Gen 3 can cover larger surfaces without needing to recharge mid-clean, something that can make a difference in homes of over 150 square metres.
Intelligent Functions
The ability to overcome obstacles differs between models. The Aqua 10 Ultra Roller and the L40s Pro Ultra can overcome simple steps, whilst the L10s Ultra Gen 3 reaches 20 mm in height.
The built-in voice assistant is available in the Aqua 10 and the L40s Pro, but not in the L10s Ultra Gen 3. All three models are compatible with external assistants such as Alexa or Google Home.
Multifunction Cleaning Base
All three devices include a multifunction base with auto-emptying, mop washing and drying. Self-cleaning of the washing tray is present in the L10s Ultra Gen 3 and the L40s Pro Ultra, both third generation. The Aqua 10 doesn't incorporate this function.
All include a detergent tank, with the Aqua 10 being the only one with a dual tank for different cleaning products. The dust bag capacity is identical in all three: 3.2 litres.
The clean water tank reaches 4 litres in the Aqua 10 compared to 4.5 litres in the other two. Dirty water is collected in 3.5 litres in the Aqua 10 and 4 litres in the L10s and L40s Pro. Minor differences that don't greatly affect daily use.
All three models offer an optional kit for connection to plumbing, although it must be purchased separately.
Dimensions
The diameter is identical in all three: 350 mm. The height varies slightly: 97.5 mm in the Aqua 10, 97 mm in the L10s Ultra Gen 3 and 103.8 mm in the L40s Pro Ultra. The Aqua 10 and the L10s can pass under lower furniture thanks to their reduced height.
The base dimensions differ notably. The Aqua 10 Ultra Roller has a wider base (420 mm) but less tall (500 mm). The L10s Ultra Gen 3 and the L40s Pro Ultra share similar dimensions: 340 mm wide and around 590 mm tall. The Aqua 10 base takes up more space horizontally, whilst the other two grow vertically.
Real-world experience
For large homes, the L10s Ultra Gen 3 offers the best autonomy with 231 minutes, sufficient to cover large spaces without interruptions. The L40s Pro Ultra also performs well in this aspect with 220 minutes.
If you live with pets, the Aqua 10 Ultra Roller and the L40s Pro Ultra are more advisable due to their dual main brush and anti-tangle side brush. The greater power of the Aqua 10 helps to collect hair embedded in carpets.
The Aqua 10's roller system proves especially effective in kitchens or areas with sticky stains. The rotating mops of the L10s and L40s Pro work well for daily maintenance.
The dirt detection of the Aqua 10 and L40s Pro allows automatic re-mopping of dirtier areas, reducing manual intervention. The L10s Ultra Gen 3, without this function, requires more initial supervision.
The possibility of automatically removing the mops from the L40s Pro proves convenient if you alternate days of vacuuming only with days of complete mopping.
Conclusion: Which one to choose?
Choose the Dreame Aqua 10 Ultra Roller if you're looking for maximum suction power and a roller mopping system that tackles difficult stains. Its 6,400 mAh battery, dual camera and dual detergent tank make it a very complete device. Ideal for homes with pets, carpets and demanding dirt. The wider base requires horizontal space.
Choose the Dreame L10s Ultra Gen 3 if you prioritise autonomy above all else. With 231 minutes of continuous operation, it's perfect for large houses. Its 97 mm height allows it to pass under low furniture. Although it lacks a camera and some advanced functions, it offers a solid balance between price and features. The third-generation tray self-cleaning reduces maintenance.
Choose the Dreame L40s Pro Ultra if you want a complete robot with dual camera, advanced dirt detection and the possibility of automatically removing the mops. Its 220 minutes of autonomy are more than sufficient for most homes. It recognises up to 180 obstacles and has remote camera access. It's the most versatile option for those seeking total automation without sacrificing intelligent functions.
