Introduction
The Dreame L40s Pro Ultra and the Dreame Matrix10 Ultra represent two advanced propositions within the brand's 2025 catalogue. We're talking about robot vacuum cleaners with complete multifunction bases, designed for users seeking to maximise home cleaning automation without sacrificing high-end features.
Both units integrate mopping systems with extendable rotating mops, laser navigation, cameras with artificial intelligence and bases that wash and dry the mops with hot water and air. However, there are notable differences in suction power, battery capacity, object recognition and additional functions that may tip the balance depending on the type of home and the specific needs of each user.
Power and Suction
The most evident difference in this Dreame robot vacuum cleaner comparison lies in the suction power. The Matrix10 Ultra reaches 30000 Pa, a figure that clearly exceeds the 19000 Pa Turbo of the L40s Pro Ultra. In homes with medium or long pile carpets, or in households with pets that shed a lot of hair, this difference can translate into deeper and more effective cleaning results.
The brushing system also presents important variations. The L40s Pro Ultra features a double anti-tangle brush, whilst the Matrix10 Ultra incorporates the double HyperStream brush, a specific Dreame design that minimises hair tangles thanks to its single-end anchoring. Both models raise the main brush during mopping to avoid dragging wet dirt, and feature an extendable, liftable and anti-tangle side brush, which guarantees effective sweeping in corners without interfering with mopping.
Mopping
Here we find notable similarities, but also details that make the difference. Both robots are equipped with double rotating mops with 3.0 extension and Roboswing system, which allows the robot to perform lateral movements to slightly introduce the mops under furniture and skirting boards. Mop lifting reaches 10.5 mm in both cases, sufficient to pass over thin carpets without wetting them.
Mop washing is carried out with hot water in both models: 75°C in the L40s Pro Ultra and hot water in the Matrix10 Ultra. Drying also uses hot air, 45°C in the former and hot air in the latter, which speeds up the process and reduces the appearance of bad odours. Both can leave the mops at the base to perform vacuum-only tasks, and detect dirt both on the mops and on the floor to adjust mopping intensity.
The major difference lies in automatic mop changing. The Matrix10 Ultra integrates a system that allows storing up to 3 pairs of interchangeable mops, a function that is not available in the L40s Pro Ultra. This can prove useful in very large homes or in situations where one prefers to keep separate mops for different areas.
The detergent tank also varies: the L40s Pro Ultra includes one, whilst the Matrix10 Ultra offers a triple system, ideal for users who wish to use different products depending on the type of floor or level of dirt.
Navigation System
The L40s Pro Ultra uses a traditional Lidar 3D turret, visible on the top of the robot. The Matrix10 Ultra, on the other hand, opts for a retractable Lidar that reduces the total height of the unit when not in use, facilitating access under low furniture. Both models incorporate dual cameras with artificial intelligence: dual camera in the L40s Pro Ultra and dual RGB camera in the Matrix10 Ultra.
Object recognition capacity is superior in the Matrix10 Ultra, with 240 identifiable obstacles compared to the 180 of the L40s Pro Ultra. This translates into more precise navigation and lower risk of collisions or blockages when faced with small or complex objects. Both recognise pets, detect curtains to avoid tangles, and allow remote camera access for home surveillance. The night vision LED is present in both, which guarantees effective navigation even in low light.
The Matrix10 Ultra specifies the use of the AI Sage 15.0 Octa-core algorithm, whilst the L40s Pro Ultra does not detail its CPU. Both feature intelligent AI cleaning and stain recognition, although the Matrix10 Ultra appears to offer a more advanced level of processing.
Autonomy and Battery
The Matrix10 Ultra has the advantage with a 6400 mAh battery that offers up to 260 minutes of autonomy. The L40s Pro Ultra, with 5200 mAh, reaches 220 minutes. The 40-minute difference can be relevant in homes of more than 150 square metres, especially if complete cleans with intensive mopping are carried out.
In practice, the robot with greater autonomy will need fewer intermediate recharges during the cleaning of large spaces, which speeds up the total process and reduces the number of trips to and from the base.
Smart Functions
Neither model includes a robotic arm, a function still uncommon in the market. However, the Matrix10 Ultra stands out for its capacity to overcome obstacles of up to 8 cm, such as steps or pronounced level changes. The L40s Pro Ultra features extendable legs that allow it to overcome between 22 and 40 mm extra, but its obstacle-crossing capacity is lower.
The voice assistant also presents differences: the L40s Pro Ultra offers a simple version, whilst the Matrix10 Ultra incorporates a complete assistant, which facilitates voice control and interaction with the robot without needing to open the app.
Multifunction Cleaning Base
Both bases fulfil auto-emptying, washing and drying functions for mops with hot water and air. The dust bag has a capacity of 3.2 litres in both cases, and the dirty water tank is 4 litres. The difference lies in the clean water tank: 4.5 litres in the L40s Pro Ultra and 5.5 litres in the Matrix10 Ultra, which allows the latter to perform more mop washing cycles without needing to refill.
Washing tray self-cleaning has evolved to the third generation in the L40s Pro Ultra and to the 3.5th generation in the Matrix10 Ultra, improving hygiene and reducing manual maintenance. Neither includes UV disinfection, but both offer a plumbing connection kit as an optional accessory, although it does not come integrated as standard.
Dimensions
The diameter is identical in both: 350 mm. The height of the L40s Pro Ultra is 103.8 mm, whilst the Matrix10 Ultra, thanks to its retractable turret, can reduce its profile to slip under lower furniture. This can make the difference in homes with low-height beds or sofas.
The bases present similar measurements: 340 mm width and 456.7 mm depth in the L40s Pro Ultra, compared to 416 mm width and 457 mm depth in the Matrix10 Ultra. The base height is practically the same: 590.5 mm in the former and 590 mm in the latter. It's advisable to measure the available space before installation, although neither base is particularly bulky for what they offer.
Real-world user experience
The Matrix10 Ultra emerges as the most complete option for large homes, especially if there are steps or level changes, thanks to its capacity to overcome up to 8 cm obstacles and its greater autonomy. The automatic mop changing system and the triple detergent tank add convenience for users seeking maximum automation and mopping customisation.
The L40s Pro Ultra, with its extendable legs and its navigation system with Lidar 3D turret, proves a solid alternative for medium-sized homes without pronounced level changes. Its 19000 Pa power is sufficient for most everyday situations, although on thick carpets or with long-haired pets the difference compared to the 30000 Pa of the Matrix10 Ultra may be noticeable.
In both cases, mopping is of a high standard thanks to washing and drying with hot water and air, and the extendable mops with Roboswing guarantee good results on edges and corners. Dirt detection automatically adjusts intensity, which optimises water and detergent consumption.
Conclusion: Which to choose?
Choose the Dreame L40s Pro Ultra if you're looking for a complete Dreame robot vacuum cleaner at a presumably more competitive price, for homes of up to 150 square metres without major level changes, and you don't need functions such as automatic mop changing or advanced voice assistant. It's a balanced option for users who value quality-price ratio without sacrificing high-end features such as hot water mopping and extendable mops.
Choose the Dreame Matrix10 Ultra if you prioritise maximum suction power, extended autonomy and capacity to overcome obstacles of up to 8 cm. The automatic mop changing, triple detergent tank and complete voice assistant make it the best 2025 robot vacuum cleaner within this comparison for large homes, with pets or with demanding cleaning needs. Its retractable turret facilitates access under low furniture, and its AI Sage 15.0 Octa-core algorithm improves precision in navigation and object recognition.
