Dreame L40 Ultra A

Introduction

The Dreame L40 Ultra A arrives on the market in April 2026 as a high-end proposition that combines vacuuming and mopping with a complete multifunctional base. This robot vacuum stands out especially for its suction power of 24,000 Pa and its mopping system with extendable mops RoboSwing, designed for those seeking minimal maintenance and consistent results on all types of surfaces.

Power and Cleaning System

With 24,000 Pa of suction power, this model sits in the high range of the current market. The suction force is especially useful for homes with pets or carpets, where embedded dirt poses a greater challenge. The main brush TriCut 3.0 combines bristles with blades designed to cut hairs before they become tangled, something that in practice considerably reduces manual maintenance of the brush. The side brush incorporates anti-tangle technology, which helps minimise hair accumulation in this area so prone to tangles. The robot's dust container has a 300 ml capacity, sufficient for several cleaning sessions before automatic emptying at the base.

Mopping System

The mopping system employs two rotating mops that spin at 180 RPM. The most interesting feature here is the mop extension with RoboSwing movement, which allows the unit to make a slight swing to bring the mops closer to edges and tuck the pad under furniture overhangs or skirting boards. The mops lift up to 10.5 mm when the robot detects carpets or when returning to the base, avoiding wetting unwanted surfaces. The robot's water tank has 80 ml, just enough for one mopping session before returning to the base to refill and wash the mops. Mopping is carried out with cold water, both in the robot and when washing mops at the base station.

Navigation and Intelligence

The Dreame L40 Ultra A uses a 360° LiDAR turret to map the environment with precision. This is complemented by a front 3D laser sensor that improves detection of low obstacles and navigation in complex spaces. The obstacle avoidance system works in real time to dodge cables, shoes or toys it encounters on its route. The CleanGenius 3.0 technology automatically adjusts cleaning parameters according to the detected dirt level and surface type, optimising both power and battery consumption. Additionally, the robot is compatible with external voice assistants such as Alexa or Google Home, facilitating control by voice commands.

Autonomy and Practical Use

The 5,200 mAh battery provides up to 230 minutes of autonomy in standard mode, which in practice translates to capacity to clean homes of up to 200-250 m² on a single charge. This figure varies depending on the selected power mode and floor type. The robot overcomes obstacles up to 20 mm in height, allowing it to navigate without problems transitions between rooms, medium-thickness carpets or small level changes. At 97 mm in height and 350 mm in diameter, the unit glides under most furniture without difficulty.

Base and Maintenance

The multifunctional base of the Dreame L40 Ultra A manages three main tasks: it automatically empties the robot's dust container into a 3.2 litre bag, washes the mops during and after each mopping session, and dries them with hot air at 45°C to prevent bad odours. The third-generation self-cleaning of the washing tray keeps the base itself in hygienic conditions without frequent manual intervention. The water tanks are generous: 4.5 litres for clean water and 4 litres for dirty water, sufficient for several complete sessions before requiring maintenance. There is the option to purchase separately a detergent tank and a plumbing connection kit to further automate water filling and emptying. The base dimensions are 340 mm wide, 590 mm high and 457 mm deep; it's advisable to measure the available space before installation.

Conclusion

The Dreame L40 Ultra A is especially suitable for medium and large homes seeking a robot mop with minimal user intervention. The combination of high suction power, mopping system with extendable mops and complete multifunctional base makes it a solid option for those who value autonomy and reduced maintenance. Especially recommended for homes with pets thanks to its TriCut 3.0 brush and its anti-tangle system.
