Dreame L40s Pro Ultra

Introduction

The Dreame L40s Pro Ultra arrives on the market in 2025 as a high-end robot vacuum that integrates advanced technology in every aspect. With 19000 Pa of suction power and a dual anti-tangle brush system, this model aims to offer complete cleaning in both vacuuming and mopping, especially designed for those looking to maximise home maintenance automation.

Power and Cleaning System

The Turbo Force 6 power of 19000 Pa places this robot mop amongst the most powerful on the current market. This suction capacity proves decisive when dealing with medium-pile carpets or floors with sand and embedded debris. The HyperStream dual main brush anti-tangle system comes fitted as standard, which makes a notable difference in homes with pets or people with long hair. This design with two brushes anchored at one end prevents hair from wrapping around the central shaft, a common problem in models with conventional brushes.

The side brush also incorporates anti-tangle technology and is additionally extendable and liftable. In practice, this means that the robot can better reach corners when sweeping and lift the brush when mopping to avoid it getting unnecessarily wet. The main brush elevation reaches a sufficient height to travel over carpets without dragging wet dirt when mopping.

Mopping System

Mopping is carried out using two rotating mops that spin at 180 RPM with 10.5 mm lifting capacity. This elevation allows the unit to climb onto carpets without wetting them, something especially useful in homes with different types of flooring. The mop extension 3.0 with RoboSwing technology enables the mops to move sideways to better reach skirting boards and edges, even getting slightly under low furniture or overhangs.

The base washes the mops with hot water at 75°C and dries them with hot air at 45°C. This third-generation self-cleaning system detects the dirt level on both the mops and the floor, adjusting the washing intensity. At the end of each cycle, the mops are left dry in the base, which prevents bad odours and bacterial growth. The integrated detergent tank allows cleaning product to be added which is automatically dispensed during mop washing.

Navigation and Intelligence

The intelligent vacuum features a 360° LIDAR turret combined with dual artificial intelligence camera and front 3D laser sensor. This triple layer of sensors enables the CleanGenius 2.0 system to recognise up to 180 different types of obstacles, from cables to toys or slippers. The dual camera with night vision LED allows the robot to work effectively even in dark rooms, and also enables remote access to view the home from the app.

Pet recognition and curtain detection are functions that demonstrate the sophistication level of the system. In practice, the robot avoids getting tangled in long curtains and can identify if there is a pet in its path to adjust its behaviour. AI stain detection makes the unit automatically persist in areas it detects as dirtier.

Battery Life and Practical Use

The 5200 mAh battery offers 220 minutes of battery life, sufficient to clean homes of up to 200-250 m² in a single cycle. This capacity proves ample for most flats and detached houses. The extra wheels 1.0 wheel system allows obstacles between 22 and 40 mm in height to be overcome, which facilitates transit between rooms with small level differences or passage over sliding door tracks.

Base and Maintenance

The multifunction station integrates a 3.2-litre dust bag, 4.5-litre clean water tank and 4-litre dirty water tank. These capacities allow several weeks of use without manual intervention, depending on the size of the home and cleaning frequency. The pipe connection kit is included, although the connection is not factory-integrated, which means it requires additional installation if you wish to fully automate water filling and emptying.

The robot has a 300 ml dust container and an 80 ml water tank, standard dimensions that are emptied and refilled automatically upon returning to the base. The station dimensions are 340 mm wide, 590.5 mm high and 456.7 mm deep, so it's advisable to ensure you have sufficient space before positioning it.

Conclusion

The Dreame L40s Pro Ultra is designed for users seeking a complete cleaning solution with minimal manual intervention. Especially suitable for large homes with pets, thanks to its anti-tangle system, high suction power and hot water mopping. A robot mop that combines high-end features with advanced navigation technology.
