Introduction
We're looking at two robots from the same brand but with completely different cleaning philosophies. The Dreame Aqua 10 Ultra Roller arrived in 2025 as a model focused on intensive mopping thanks to its rotating roller, whilst the Dreame L40 Ultra appeared in 2024 with a more balanced approach between vacuuming and mopping using rotating mops. Both units incorporate a complete multifunctional base, which guarantees automated mopping maintenance.
The choice between one or the other will depend mainly on the type of flooring in your home and whether you prioritise suction power or a more aggressive mopping system. The roller model is designed for those looking to remove ingrained dirt on hard floors, whilst the mop version offers greater versatility and autonomy.
Power and Suction
The most striking difference between these models is raw power. The Aqua 10 Ultra Roller reaches 30,000 Pa, a figure that almost triples the L40 Ultra's 11,000 Pa. This superior power is particularly noticeable on long-pile carpets or in homes with heavy dirt accumulation. However, in daily use on hard floors, both models offer more than sufficient results.
The brushing system also shows important differences. The Aqua 10 features a dual HyperStream brush, designed to prevent hair tangles using two brushes anchored at one end. The L40 Ultra incorporates the TriCut 3.0 system, which combines bristles with blades that cut tangled hair. Both systems are effective, although the HyperStream is more suitable for homes with pets due to its lower tendency to tangle.
Both units feature an extendable side brush that lifts during mopping, plus anti-tangle technology. This facilitates corner cleaning and prevents the side brush from interfering when the robot is mopping. For homes with animals, either option works correctly.
Mopping
This is where the differences become most evident. The Dreame Aqua 10 Ultra Roller opts for a rotating roller with 12N of pressure, a system that allows more intensive mopping and removes ingrained stains. This roller is especially effective in kitchens or high-traffic areas where dirt adheres to the floor.
The L40 Ultra uses two rotating mops with side extension and RoboSwing movement, which allows it to slightly insert the mop under furniture and edges. This system is more versatile and covers edges better, although it doesn't exert as much pressure on the floor as the roller.
Mop lift also varies. The roller model can raise its mopping system up to 14 mm and includes an additional protective cover, which ensures carpets don't get wet. The L40 Ultra lifts its mops up to 10.5 mm, sufficient for medium-thickness carpets.
A clear advantage of the L40 Ultra is its ability to automatically remove the mops at the base when you only want to vacuum. The Aqua 10 doesn't offer this function, although its protective cover minimises the problem. Both models detect dirt on the mops and floor, adjusting mopping intensity as needed.
Navigation System
Both robots incorporate LiDAR technology, although with differences in implementation. The Aqua 10 Ultra Roller features retractable LiDAR, whilst the L40 Ultra uses a 3D LiDAR turret. Both systems allow precise home mapping and efficient navigation.
Regarding artificial intelligence, the Aqua 10 stands out with its AI Sage 15.0 Octa-core processor, capable of recognising up to 240 different obstacles. The L40 Ultra features the AI Sage 11.0 Quad-core and recognises 100 objects. This difference translates into more refined obstacle avoidance in the more recent model, especially useful in homes with many objects on the floor or with young children.
Both units incorporate dual RGB cameras, front 3D laser sensor, night vision LED and remote camera access. They also recognise pets and curtains, adjusting their behaviour according to the environment. The CleanGenius AI system is present in both models, enabling intelligent cleaning based on the type of dirt detected.
Autonomy and Battery
The Dreame Aqua 10 Ultra Roller features a 6,400 mAh battery that allows it to run for 160 minutes. The L40 Ultra, with its 5,200 mAh, achieves 194 minutes of autonomy. It may seem contradictory that a smaller battery offers more autonomy, but the explanation lies in suction power: the Aqua 10's 30,000 Pa consumes more energy.
In homes up to 150 square metres, either model completes cleaning without needing to recharge. For larger surfaces, the L40 Ultra has an advantage by offering more continuous running time, although the Aqua 10 compensates with greater speed thanks to its superior power.
Smart Features
The ability to overcome obstacles differs notably. The Aqua 10 Ultra Roller incorporates a simple step system that allows it to navigate uneven surfaces, whilst the L40 Ultra can overcome obstacles up to 22 mm in height. The latter is more practical in homes with transitions between different floor types or small steps.
Both robots feature their own voice assistant and are compatible with Alexa and Google Home. Integration with the home ecosystem is complete in both cases, allowing voice control and advanced scheduling from the app.
Multifunctional Cleaning Base
Both bases offer auto-emptying of the dust bin, hot water mop washing and detergent tank. The Aqua 10 Ultra Roller incorporates a dual detergent tank, which allows using different products depending on floor type or desired cleaning intensity. The L40 Ultra has a single tank.
The L40 Ultra's mop drying uses hot air, a fact confirmed in the table. The Aqua 10 doesn't specify drying temperature in the available information. Auto-cleaning of the washing tray is only present in the L40 Ultra, which incorporates a second-generation system that reduces manual maintenance.
Dust bag capacity is identical: 3.2 litres in both cases. Water tanks vary slightly: the Aqua 10 has 4 litres of clean water and 3.5 of dirty water, whilst the L40 Ultra features 4.5 litres of clean water and 4 of dirty water. These differences are minimal in daily use.
Both models offer an optional kit for plumbing connection, which must be purchased separately. This function automates water filling and emptying, although it doesn't come integrated as standard in either unit.
Dimensions
The Dreame Aqua 10 Ultra Roller measures 97.5 mm in height, which allows it to slip under furniture more easily than the L40 Ultra, which reaches 103.8 mm. This 6.3 mm difference can make a difference in homes with low furniture or beds with little clearance from the floor.
The diameter is identical in both: 350 mm. The bases, however, have very different dimensions. The Aqua 10's measures 420 mm wide, 500 mm high and 440 mm deep. The L40 Ultra's is narrower (340 mm) but taller (590.5 mm) and slightly deeper (456.7 mm). It's advisable to measure available space before deciding, especially if the base will go in a tight space.
Real-World Experience
For large homes with predominantly hard floors and a need for intensive mopping, the Aqua 10 Ultra Roller offers better results. Its pressure roller removes stains that conventional mops can't drag away, and its dual detergent tank allows customising cleaning according to the area.
The L40 Ultra is more balanced for homes with a mix of hard floors and carpets. Its ability to automatically remove mops at the base facilitates vacuum-only sessions, and its greater autonomy is an advantage on large surfaces. Auto-cleaning of the washing tray reduces manual maintenance, something appreciated in the long term.
In homes with pets, the Aqua 10's dual HyperStream brush minimises hair tangles, although the L40's TriCut 3.0 also works correctly. The Aqua 10's greater suction power facilitates picking up hair embedded in carpets.
If furniture height is limited, the Aqua 10 has a clear advantage with its 97.5 mm. For homes with small steps or transitions between floors, the L40 Ultra overcomes these obstacles better thanks to its ability to cross up to 22 mm.
Conclusion: Which to Choose?
Choose the Dreame Aqua 10 Ultra Roller if: you prioritise suction power and need intensive mopping with a roller. It's ideal for homes with hard floors, kitchens with lots of grease or high-traffic areas where stains become ingrained. Also if you have low furniture and need a robot with lower height. The dual detergent tank adds versatility for different types of cleaning.
Choose the Dreame L40 Ultra if: you're looking for a balance between vacuuming and mopping with rotating mops. Its ability to automatically remove mops at the base makes it more convenient for vacuum-only sessions. Greater autonomy benefits large homes, and its system for overcoming obstacles up to 22 mm is practical in homes with transitions between floors. Auto-cleaning of the washing tray reduces manual maintenance, an advantage if you prefer to intervene as little as possible.
