Introduction
The Dreame L40 Ultra AE and the Mova E40 Ultra are two high-end robot vacuum cleaners launched in 2025 that share more than might appear at first glance. Mova is Dreame's second brand, which explains the numerous technical similarities between both models. Both units offer 19000 Pa suction power in Turbo mode, a multifunctional base with mop washing and drying, and advanced laser navigation. However, the differences lie in the details: the Dreame L40 Ultra AE incorporates premium features that position it a step above in terms of artificial intelligence and automation.
These are robots designed for those seeking a complete and autonomous cleaning system, especially useful in medium or large homes where regular mopping is important. The presence of a multifunctional base in both cases makes the difference compared to more basic models, guaranteeing always-clean mops during mopping.
Power and Suction
Both robots reach 19000 Pa in Turbo mode, a figure that places them amongst the most powerful on the current market. This power is sufficient for medium-pile carpets and floors with adhered dirt.
The main difference lies in the main brush. The Dreame L40 Ultra AE features the TriCut 3.0, a system that combines bristles with blades to cut tangled hair, considerably reducing maintenance. This brush lifts during mopping, preventing moisture from wetting it unnecessarily. The Mova E40 Ultra is equipped with a simple brush that can be fitted with anti-tangle function, but it doesn't come installed as standard and doesn't have automatic lifting.
As for side brushes, neither model offers corner extension nor lifting during mopping. The Mova E40 Ultra does incorporate an anti-tangle side brush, something the Dreame L40 Ultra AE doesn't feature. For homes with long-haired pets, this can make a difference in side brush maintenance, although the main brush remains more decisive in overall vacuuming effectiveness.
Mopping
Both robots use a dual rotating mop system with 3.0 extension and Roboswing technology, which allows the robot to make a movement to slightly insert the mop under furniture or ledges. Mop lifting reaches 10.5 mm in both cases, sufficient to pass over thin carpets without wetting them.
This is where the Dreame L40 Ultra AE pulls ahead. It washes mops with hot water at 75°C, which significantly improves the removal of grease and bacteria. The Mova E40 Ultra washes with cold water, less effective for difficult stains. Both dry mops at 45°C, a temperature that helps prevent bad odours.
The Dreame L40 Ultra AE incorporates dirt detection both on the mops and on the floor. This means the robot identifies when the mops are dirty and automatically washes them again, and also detects dirtier floor areas for intensive scrubbing. The Mova E40 Ultra lacks these functions, performing more standard mopping without automatic adjustments according to dirt level.
Neither allows leaving the mops at the base to perform vacuuming only, something that some high-end competitors do offer.
Navigation System
Both units feature LIDAR 3.0 turret and front 3D laser sensor for obstacle avoidance. Laser navigation guarantees precise mapping and orderly movement throughout the home.
The fundamental difference lies in the AI camera. The Dreame L40 Ultra AE integrates a front camera with recognition of up to 120 different obstacles, remote access for surveillance from your mobile, and LED for night vision. This allows using the robot as a security camera when it's not cleaning. The Mova E40 Ultra doesn't have an AI camera, so its object recognition capability is more limited and doesn't offer remote access.
Both robots recognise pets and adjust their behaviour to avoid disturbing them. The Dreame L40 Ultra AE also detects curtains, avoiding getting tangled in them during cleaning. Both include the CleanGenius AI system to optimise routes and cleaning modes according to the type of dirt and surface.
Battery Life and Battery
Battery capacity is identical: 5200 mAh in both cases. The Mova E40 Ultra specifies a battery life of 210 minutes, more than three hours of continuous operation that allows covering large homes without the need for intermediate recharging. The Dreame L40 Ultra AE doesn't provide this data, although as they share the same battery, the battery life should be similar.
In practice, with 5200 mAh and 19000 Pa power, these robots can clean surfaces of more than 200 square metres in a single cycle, provided maximum power mode isn't used constantly.
Smart Features
Both robots overcome obstacles up to 20 mm in height, which allows them to pass over medium-thickness carpets, thick cables or small level differences between rooms without getting blocked.
Both models use CleanGenius AI to automatically adapt suction power and water flow according to the type of surface and detected dirt level. This function reduces battery consumption in lightly soiled areas and increases intensity where it's really needed.
Multifunctional Cleaning Base
Both bases have similar capacities: 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 the need for constant maintenance.
The Dreame L40 Ultra AE incorporates second-generation tray self-cleaning already installed as standard, a system that cleans the tray itself where the mops are washed to prevent dirt accumulation. The Mova E40 Ultra has a second-generation system, but requires additional installation or doesn't come factory-fitted.
Only the Dreame L40 Ultra AE includes a detergent tank, which allows adding cleaning product that is automatically dispensed during mop washing. The Mova E40 Ultra doesn't offer this option, limiting itself to water use.
The Dreame L40 Ultra AE also has a plumbing connection kit, which is purchased separately and allows connecting the base directly to the drain and water supply for total automation. The Mova E40 Ultra doesn't offer this possibility. Although it's not an essential function, for those seeking maximum autonomy it's interesting.
Neither model includes UV disinfection in the base.
Dimensions
The measurements are identical on both robots and bases. The robot measures 350 mm in diameter and 97 mm in height, standard dimensions that allow it to pass under most furniture with legs of at least 10 cm in height. The base is 340 mm wide, 590.5 mm high and 456.7 mm deep, occupying considerable space that should be taken into account before purchase.
Real-World Experience
For homes with pets, the Dreame L40 Ultra AE offers a clear advantage thanks to the TriCut 3.0 anti-tangle brush and floor dirt detection, which allows intensive scrubbing in areas where animals spend more time. The Mova E40 Ultra partially compensates with its anti-tangle side brush, but the main brush remains more decisive.
In large homes, both robots work well thanks to the 5200 mAh battery. The Mova E40 Ultra specifies 210 minutes of battery life, sufficient for more than 200 square metres. The LIDAR navigation system ensures they don't repeat areas or leave zones uncleaned.
For those who value deep mopping, the 75°C mop washing of the Dreame L40 Ultra AE makes a real difference in kitchens and bathrooms where grease accumulates. The Mova E40 Ultra with cold water performs adequately, but doesn't achieve the same level of hygiene.
The AI camera on the Dreame L40 Ultra AE adds extra peace of mind: it allows remote home monitoring and ensures better avoidance of small objects such as toys or cables. The Mova E40 Ultra, without a camera, may have more difficulties with obstacles not detected by the 3D laser.
The robot's dust bin is larger on the Dreame L40 Ultra AE (395 ml versus 300 ml), which slightly reduces the frequency with which the robot must return to the base during cleaning in very dirty homes.
Conclusion: Which to Choose?
Choose the Dreame L40 Ultra AE if you're looking for the maximum level of automation and features. The mop washing with hot water at 75°C, the AI camera with remote access, dirt detection on mops and floor, the detergent tank and the TriCut 3.0 brush with automatic lifting justify the price difference. It's the option for those who have long-haired pets, value deep mopping and want a robot that intelligently adapts to each situation. It's also ideal if you're interested in the remote surveillance function through the camera.
Choose the Mova E40 Ultra if you're looking for a complete robot with multifunctional base at a more competitive price. It shares the same suction power, mopping system with extendable and liftable mops, and precise laser navigation. The anti-tangle side brush can be advantageous in some cases. You lose premium features such as the AI camera, hot water washing and intelligent dirt detection, but you get a capable unit for daily cleaning in homes without special requirements. Perfect for those who prioritise value for money without giving up a multifunctional base.
