Dreame L40s Pro Ultra vs Dreame Matrix10 Ultra vs Roborock Saros 10R

Introduction

This comparison pits three high-end robots launched in 2025 against each other: the Dreame L40s Pro Ultra and the Dreame Matrix10 Ultra, both from the Chinese firm Dreame, alongside the Roborock Saros 10R, belonging to the world's leading brand in cleaning robotics. All three units integrate a multifunctional base with mop washing and drying, advanced AI navigation systems with dual cameras, as well as simultaneous vacuuming and mopping capabilities. These are models designed for demanding users seeking maximum automation in medium or large homes, with the ability to manage different types of flooring, pets and complex obstacles without manual intervention.

The Dreame Matrix10 Ultra positions itself as the most powerful of the three, whilst the Roborock Saros 10R opts for a compact design and proven proprietary technology. The L40s Pro Ultra remains as an intermediate option within the Dreame catalogue.

Power and Suction

The most striking difference lies in suction power. The Dreame Matrix10 Ultra leads with 30,000 Pa, a figure that far exceeds the 19,000 Pa of the L40s Pro Ultra and the 18,500 Pa of the Roborock Saros 10R. In practice, this translates to greater capacity to extract ingrained dirt from carpets or tile joints, especially useful in homes with pets that shed abundant hair.

All three models feature anti-tangle main brushes with proprietary technologies. The L40s Pro Ultra and Matrix10 Ultra utilise Dreame's Doble Cepillo HyperStream system, designed with two brushes anchored at one end that minimise hair tangles. The Saros 10R incorporates Roborock's DuoDivide brush, which pushes hairs towards the central gap to facilitate direct suction. Both systems work well, although the approach differs slightly.

All three robots lift the main brush during mopping and feature an extendable and liftable side brush, also anti-tangle. This allows better sweeping of corners when vacuuming and prevents the side brush from dragging wet dirt during mopping. There are no notable differences in this area.

Mopping

All employ two rotating mops, but differences appear in the details. The L40s Pro Ultra and the Matrix10 Ultra integrate the Roboswing system, which makes the robot perform a lateral movement to slightly introduce the mop under furniture or protrusions. The Saros 10R does not specify this movement, although it also extends the mops to mop edges.

Mop lifting marks a distance: the Roborock Saros 10R lifts the mops between 12 and 22 mm, which ensures they don't touch thick carpets. The two Dreame models stay at 10.5 mm, sufficient for thin carpets but less versatile on high-pile carpets.

Hot water mopping is exclusive to the Dreame Matrix10 Ultra, which mops the floor at 80°C. The Saros 10R uses warm water and the L40s Pro Ultra cold water. Mopping with hot water helps dissolve grease and stuck-on stains, especially in kitchens. The Matrix10 Ultra also stands out for its triple detergent tank, compared to the simple tank of the other two models, allowing different products to be used depending on the type of flooring or level of dirt.

Mop washing in the base is carried out with hot water in all three cases. The L40s Pro Ultra washes at 65°C, the Matrix10 Ultra at 75°C and the Saros 10R at 60°C. Drying also uses hot air in all: 55°C in the Dreame models and 60°C in the Roborock. Self-cleaning of the washing tray is present in all three, with the Matrix10 Ultra boasting third generation 3.5, the L40s Pro Ultra third generation and the Saros 10R second generation 2.0.

A differential feature of the Matrix10 Ultra is automatic mop changing. The base stores 3 pairs of mops that the robot can swap autonomously, extending cleaning without human intervention. Neither of the other two models offers this feature.

All three detect dirt both on the mops and on the floor, adjusting mopping as necessary. Additionally, they allow the mops to be automatically removed at the base to perform vacuum-only tasks without dragging moisture.

Navigation System

The L40s Pro Ultra features a traditional LiDAR turret, whilst the Matrix10 Ultra integrates retractable LiDAR, which hides when not in use, reducing the robot's overall height. The Saros 10R uses Roborock's StarSight 2.0 system, which combines LiDAR with additional sensors to improve precision.

All three feature dual RGB cameras with AI and front 3D laser sensor to avoid obstacles. The difference lies in recognition capacity: the Matrix10 Ultra identifies up to 240 different objects, the L40s Pro Ultra recognises 180 and the Saros 10R stays at 108. More recognition means better adaptation to complex environments with toys, cables, slippers or clothes on the floor.

Both Dreame models detect curtains and adjust their behaviour to avoid tangling, something the Saros 10R does not specify. All three recognise pets, offer remote camera access from the mobile and feature LEDs for night vision.

In terms of artificial intelligence, the Matrix10 Ultra uses the AI Sage 15.0 processor with Neuro Vision algorithm, whilst the Saros 10R employs the RR Mason 11.0. The L40s Pro Ultra does not specify a particular processor, although it also integrates CleanGenius AI for intelligent cleaning. All three recognise stains and adjust cleaning accordingly.

Runtime and Battery

The Dreame Matrix10 Ultra and the Roborock Saros 10R share a 6,400 mAh battery, superior to the 5,200 mAh of the L40s Pro Ultra. However, effective runtime varies: the Matrix10 Ultra reaches 260 minutes, the L40s Pro Ultra 220 minutes and the Saros 10R 180 minutes. This is due to the energy consumption of each model, influenced by suction power and system efficiency.

For large homes, the Matrix10 Ultra offers the best combination of battery and runtime. The Saros 10R, despite having the same battery capacity, consumes more quickly, probably due to its more complex navigation system.

Smart Features

All three robots overcome simple thresholds of up to 2 cm, facilitating passage between rooms with small level changes or thick carpets. None incorporates a robotic arm.

All integrate their own voice assistant and are compatible with external assistants such as Alexa or Google Home, allowing voice control without needing to open the app.

Multifunctional Cleaning Base

All three bases offer auto-emptying of the dust bin, washing and drying of mops with hot water and air. The dust bag capacity is 3.2 litres in the Dreame models compared to 2.5 litres in the Roborock, which means fewer bag changes in the former.

The clean water tank reaches 5.5 litres in the Matrix10 Ultra, 4.5 litres in the L40s Pro Ultra and 4 litres in the Saros 10R. The dirty water tank measures 4 litres in the Dreame models and 3 litres in the Roborock. Greater capacity means more mopping autonomy without manually refilling or emptying tanks.

Both Dreame models offer an optional plumbing connection kit, which is purchased separately and allows automation of water filling and emptying. The Roborock Saros 10R does not have this option. None of the three comes with integrated connection from the factory.

UV disinfection is not present in any of the three models.

Dimensions

The Roborock Saros 10R is the lowest at 79.8 mm in height, followed by the Dreame Matrix10 Ultra at 89 mm and the L40s Pro Ultra at 103.8 mm. This difference is important if you need the robot to pass under low furniture, sofas or beds with little space. The Saros 10R slips more easily under almost any standard furniture.

The diameter is similar in all three: 350 mm in the Dreame models and 353 mm in the Roborock. There is no practical advantage between them in this aspect.

The bases also differ. The Matrix10 Ultra's measures 416 mm wide, 590 mm high and 457 mm deep. The L40s Pro Ultra's measures 340 mm wide, 590.5 mm high and 456.7 mm deep. The Saros 10R's is more compact in height (488 mm) but somewhat wider (381 mm) and deeper (475 mm). It's advisable to measure the available space before choosing.

Real-World Experience

For large homes over 150 m², the Dreame Matrix10 Ultra offers the best combination: maximum power, extended runtime, large tanks and automatic mop changing. Its ability to recognise 240 obstacles and mop with hot water make it the most complete option.

In homes with pets that shed a lot of hair, the 30,000 Pa power of the Matrix10 Ultra makes a difference compared to the other two. All three anti-tangle brushes work well, but greater suction facilitates extraction of hair embedded in carpets.

If you need the robot to pass under low furniture, the Roborock Saros 10R is the best option with its 79.8 mm height. It also stands out for lifting the mops up to 22 mm, ideal for thick carpets you want to protect from water.

For users who value total automation without frequent maintenance, the Matrix10 Ultra leads again thanks to automatic mop changing, larger tanks and triple detergent system.

The Dreame L40s Pro Ultra remains as a balanced option: it offers good features at an intermediate level, although its greater height (103.8 mm) limits access under certain furniture.
