Dreame L40 Ultra AE

Introduction

The Dreame L40 Ultra AE arrives on the market in 2025 as a comprehensive proposition within the high-end range of robot vacuum cleaners with multifunctional base. It stands out particularly for its suction power of 19000 Pa with Turbo Force 6 technology and a mopping system with extendable mops RoboSwing 3.0, features that position it as an advanced solution for those seeking to fully automate home cleaning.

Power and Cleaning System

The power of 19000 Pa places this model in a high suction range, sufficient for medium-pile carpets and floors with ingrained dirt. The main brush TriCut 3.0 comes with an anti-tangle system already installed, which is especially useful in homes with pets or people with long hair. This type of brush combines bristles with blades that cut hairs before they become tangled, notably reducing manual maintenance. Additionally, the main brush is liftable, a function that allows the robot to better adapt to different surfaces and avoid dragging dirt from carpets to mopping areas. The 5200 mAh battery provides good energy capacity, although the manufacturer does not specify the exact autonomy in minutes.

Mopping System

The mopping system incorporates two rotating mops that spin at 180 RPM, a speed that allows scrubbing of dirt adhered to the floor. Most interesting is the mop extension RoboSwing 3.0, which allows the robot to perform a lateral movement to better reach edges and corners, areas typically problematic in conventional mopping robots. The mops lift up to 10.5 mm when the robot detects carpets or rugs, avoiding wetting them during the cleaning process. The base washes the mops with hot water at 75°C and dries them with hot air at 45°C, a complete process that guarantees hygiene and eliminates bad odours. During mopping, the unit automatically returns to the base to wash the mops when it detects they are dirty, both through sensors in the mops themselves and by detecting dirt on the floor. This continuous washing cycle ensures that mopping is always done with clean mops.

Navigation and Intelligence

The Dreame L40 Ultra AE features a 360° LIDAR turret to map the home with precision, complemented with an artificial intelligence camera and a front 3D laser sensor. This combination allows it to recognise up to 120 different types of obstacles, including pets, cables, slippers and other everyday objects. The CleanGenius 2.0 system automatically adjusts cleaning parameters according to the type of dirt and surface detected, optimising suction power, water flow and mopping passes. The camera incorporates night vision LED and allows remote access, a useful function for monitoring the home or locating pets when you are not present. With a height of 97 mm and capacity to overcome obstacles up to 20 mm, the robot can access under low furniture and navigate cables or small level changes without getting stuck.

Autonomy and Practical Use

The robot's internal dust container has a capacity of 395 ml, whilst the water tank reaches 80 ml. These figures are standard in robots with self-emptying base, as the unit automatically empties the dust into the 3.2 L bag in the base after each clean. In practice, this means you can forget about maintenance for several weeks. Its diameter of 350 mm is typical for this type of device, allowing a good balance between manoeuvrability and cleaning capacity.

Base and Maintenance

The second-generation multifunctional base includes a self-cleaning system for the washing tray itself, an improvement that prevents dirt accumulation in the internal ducts. The tanks are generous: 4.5 L for clean water and 4 L for dirty water, sufficient capacity for multiple mopping cycles without manual intervention. It includes a detergent tank that is automatically dispensed during mop washing. For those who prefer to completely forget about refilling and emptying tanks, the model accepts a plumbing connection kit, although it does not come integrated as standard. The base dimensions are 340 mm wide, 590.5 mm high and 456.7 mm deep, measurements to consider when locating it in the available space.

Conclusion

The Dreame L40 Ultra AE is especially suitable for medium and large homes with a combination of hard floors and carpets, where its suction power, advanced mopping system and intelligent obstacle management make the difference. It is a solid option for homes with pets thanks to the anti-tangle brush and for those seeking to minimise manual maintenance of the robot vacuum cleaner.
