Introduction
The Dreame D10 Plus Gen 2 and the Dreame L40s Pro Ultra represent two distinct philosophies within the brand's catalogue. The former, launched in 2024, positions itself as a vacuuming solution with auto-emptying, ideal for those seeking basic automation without complications. The latter, from 2025, belongs to the high-end range with a complete multifunction base and advanced artificial intelligence technology.
We're looking at a robot vacuum comparison that clearly reflects the differences between a functional model and one designed to offer total autonomous cleaning. The D10 Plus Gen 2 vacuums effectively and empties itself, whilst the L40s Pro Ultra adds professional mopping, hot water mop washing and an arsenal of sensors that completely transform the user experience.
Power and Suction
The difference in suction power is considerable. The Dreame D10 Plus Gen 2 reaches 6,000 Pa, sufficient for hard floors and short-pile carpets. The Dreame L40s Pro Ultra triples this figure with 19,000 Pa, an impressive amount that makes a difference on dense carpets or when there are pets at home.
The brushing system also evolves radically. The D10 Plus Gen 2 features a simple silicone brush, effective but without great technical flourishes. The L40s Pro Ultra incorporates the dual HyperStream brush, specifically designed to prevent hair tangles thanks to its design anchored at one end. This detail is particularly noticeable in homes with long-haired pets.
Only the high-end model lifts the main brush during mopping, preventing it from getting unnecessarily wet. It also includes an extendable side brush that reaches corners better, and can be raised when not needed. The L40s Pro Ultra's side brush also features an anti-tangle system, something the D10 Plus Gen 2 doesn't offer.
Mopping
Here we find the most pronounced gap between these two Dreame robot vacuums. The D10 Plus Gen 2 features a static mop that drags moisture across the floor, without lifting or extension capability. It's token mopping, useful for light maintenance but little more.
The Dreame L40s Pro Ultra changes the game with two rotating mops that spin at 180 RPM. It includes side extension that reaches edges and the RoboSwing system, which allows the robot to make a characteristic movement to get the mop under furniture and overhangs. The mops lift 10.5 mm when it detects carpets or when returning to the base.
The L40s Pro Ultra's multifunction base washes the mops with hot water at 75°C during the cleaning session, ensuring it always mops with clean mops. Afterwards it dries them with hot air at 45°C to prevent bad odours. It includes dirt detection both on the mops and on the floor, automatically adjusting mopping intensity. It can even remove the mops at the base when you only need to vacuum.
The D10 Plus Gen 2 lacks all of this: no washing, no drying, no dirt detection. For homes where mopping is a priority, the choice is clear.
Navigation System
Both feature 360° LiDAR turret for mapping the home, but that's where the similarities end. The D10 Plus Gen 2 is limited to this basic system, without cameras or additional sensors for object recognition.
The L40s Pro Ultra adds dual camera with artificial intelligence, front 3D laser sensor and capability to recognise up to 180 different types of obstacles. It identifies pets, detects curtains to treat them carefully and allows remote access to the camera from the app. The night vision LED ensures it works properly even in low light.
The premium model's CleanGenius 2.0 system automatically adjusts cleaning according to the type of dirt detected. It recognises stains and adapts the mopping strategy accordingly. In practice, this means the robot vacuum makes intelligent decisions without user intervention.
Battery Life and Battery
Both feature 5,200 mAh batteries, but performance differs. The Dreame D10 Plus Gen 2 achieves 285 minutes of battery life, taking advantage of its lower energy consumption. The L40s Pro Ultra, with all its technology and greater power, manages 220 minutes.
For medium or small-sized homes, either completes cleaning without problems. In large houses, the D10 Plus Gen 2 may have an advantage if you need to cover a lot of surface area in one go, although the L40s Pro Ultra compensates with greater efficiency thanks to its intelligent navigation.
Smart Features
The Dreame D10 Plus Gen 2 overcomes obstacles up to 20 mm in height, sufficient for most transitions between rooms. The L40s Pro Ultra goes further: 22 mm on simple steps and up to 40 mm on double steps, allowing it to navigate obstacles that would stop the basic model.
Only the L40s Pro Ultra includes its own voice assistant integrated into the robot, in addition to Alexa and Google Home compatibility that the D10 Plus Gen 2 also offers. This feature allows you to control the robot using voice commands without needing to take out your mobile.
Multifunction Cleaning Base
The D10 Plus Gen 2's base focuses on auto-emptying the dust bin, with a 4-litre bag that allows you to forget about maintenance for weeks. It doesn't wash mops because the mopping system doesn't require it, nor does it include a detergent tank.
The Dreame L40s Pro Ultra features a third-generation multifunction base that does everything. It auto-empties dust into a 3.2-litre bag, washes mops with hot water at 75°C, dries them with hot air at 45°C and self-cleans the washing tray to prevent dirt accumulation. It includes a detergent tank that automatically dispenses during mop washing.
The water tanks are generous: 4.5 litres of clean water and 4 litres of dirty water. There's an optional plumbing connection kit available for separate purchase, although the connection doesn't come integrated as standard. With these tanks, the robot can mop large homes without needing to refill manually.
Dimensions
Both robots share a diameter of 350 mm, but height varies. The D10 Plus Gen 2 measures 96.3 mm, allowing it to slip under low furniture more easily. The L40s Pro Ultra reaches 103.8 mm, barely 7.5 mm more that can make a difference under very tight beds or sofas.
The bases also differ considerably. The D10 Plus Gen 2's occupies 298 mm width, 427 mm height and 406 mm depth. The L40s Pro Ultra's, with all its technology, requires more space: 340 mm width, 590.5 mm height and 456.7 mm depth. It's worth measuring the available space carefully before deciding on the premium model.
Real-World Experience
The Dreame D10 Plus Gen 2 works well in small or medium-sized homes where mopping isn't a priority. Its greater battery life and lower height allow it to clean single-storey houses without complications, slipping under furniture without problems. The silicone brush reduces tangles, although not to the level of the HyperStream system.
For homes with pets, the L40s Pro Ultra offers clear advantages: greater suction power, dual design anti-tangle brush and specific animal recognition that prevents accidents. Dirt detection automatically adjusts cleaning in areas where pets spend more time.
On hard floors and parquet, both work correctly in vacuum mode. For real mopping, only the L40s Pro Ultra offers professional results thanks to continuous mop washing with hot water. The D10 Plus Gen 2 simply passes a damp mop, useful for maintenance but insufficient for stuck-on dirt.
The premium model's ease of use is superior: automatic mop removal when you only need to vacuum, intelligent detection that adapts cleaning, remote camera access for surveillance. The D10 Plus Gen 2 requires more manual intervention and planning from the user.
Conclusion: Which to Choose?
Choose the Dreame D10 Plus Gen 2 if you're looking for a functional robot vacuum without great pretensions, your home is small or medium-sized, you don't have thick carpets or long-haired pets, and mopping is secondary. Its greater battery life and lower height are advantages in single-storey flats with low furniture. The value for money is interesting if you don't need professional mopping.
Choose the Dreame L40s Pro Ultra if you want to completely forget about cleaning, you have pets, you need real mopping with always-clean mops, your house has carpets or fitted carpets, and you value artificial intelligence for obstacle recognition. It's the best robot vacuum in this comparison for large homes where total autonomy and professional mopping justify the investment. The multifunction base with washing at 75°C and hot air drying makes the difference between really mopping or simply dampening the floor.
