Introduction
The Dreame D20 Pro Plus, the Dreame L10s Ultra Gen 3 and the Roborock Saros 10R represent three distinct propositions within the 2025 robot vacuum market. Whilst the first two share the same manufacturer, their features differ notably in terms of mopping capabilities and autonomy. The third, from the world's leading brand in this sector, focuses on advanced navigation technology and intelligent functions.
The D20 Pro Plus stands out for its auto-empty base without mop washing, which positions it as an option centred on vacuuming with basic mopping. The L10s Ultra Gen 3 incorporates a complete multifunction base with mop washing and drying. The Saros 10R takes technology a step further with dual AI camera, advanced dirt detection and an especially compact design in height.
Power and Suction
The difference in suction power marks significant distances between these models. The L10s Ultra Gen 3 reaches 25,000 Pa, almost double the D20 Pro Plus with its 13,000 Pa. The Saros 10R sits in the middle ground with 18,500 Pa, sufficient for most domestic situations.
Regarding the brushing system, the D20 Pro Plus features a dual HyperStream brush, specifically designed to prevent hair tangles. The L10s Ultra Gen 3 is equipped with a traditional single brush, whilst the Saros 10R incorporates Roborock's DuoDivide anti-tangle system, which pushes hair towards the central gap to facilitate suction.
All three include an extendable side brush to improve corner cleaning. However, only the Saros 10R offers lifting of both the main brush and the side brush during mopping, which prevents dragging dry dirt onto wet surfaces. The D20 Pro Plus and the Saros 10R incorporate an anti-tangle side brush, a feature absent on the L10s Ultra Gen 3.
Mopping
Here we find substantial differences that define the profile of each Dreame robot vacuum and the Roborock model. The D20 Pro Plus uses a static mop without extension or lifting capability, which limits its effectiveness on edges and prevents it from adapting to carpets. Its base does not include mop washing, so these must be cleaned manually.
The L10s Ultra Gen 3 makes a qualitative leap with two rotating mops that extend using the Roboswing system to better reach edges. These mops lift 10.5 mm when the robot detects carpets. The multifunction base washes the mops with hot water and dries them with hot air, ensuring they are always clean during the mopping process.
The Saros 10R also features two rotating mops with edge extension, but its lifting reaches between 12 and 22 mm, surpassing the Dreame model. Additionally, it mops with warm water directly onto the floor, not only when washing mops. It incorporates dirt detection on both the mops and the floor, enabling automatic re-mopping in particularly dirty areas. The base washes with hot water and dries with hot air. An additional advantage: it can automatically detach the mops at the base to perform vacuum-only sessions without dragging the mops.
Navigation System
All three robots use a LiDAR turret to map the home, but the differences in artificial intelligence are notable. The D20 Pro Plus has a front 3D laser sensor to avoid obstacles, but lacks an AI camera and does not specifically recognise pets.
The L10s Ultra Gen 3 maintains the 3D laser sensor and adds pet recognition through its CleanGenius system, although without a visible AI camera. This function is useful in homes with animals, as the robot can adjust its behaviour when it detects their presence.
The Saros 10R is equipped with the StarSight 2.0 system with dual AI camera capable of recognising up to 108 different types of obstacles, including pets. It incorporates night vision LEDs to navigate correctly even in low light. An exclusive feature is remote camera access, which allows viewing the home from the app. Its RR Mason 11.0 algorithm and the SmartPlan function optimise cleaning routes based on environmental analysis. Furthermore, it recognises specific stains using AI to focus on those areas.
Autonomy and Battery
Battery capacity varies considerably. The Saros 10R features 6,400 mAh, compared to the 5,200 mAh of the two Dreame models. However, actual autonomy depends on each system's consumption.
In practice, the D20 Pro Plus offers 285 minutes of operation, the highest figure in this robot vacuum comparison. The L10s Ultra Gen 3 reaches 231 minutes, whilst the Saros 10R remains at 180 minutes despite its larger battery. This is explained by the higher consumption of its AI systems, cameras and advanced functions.
For medium or large-sized homes, the D20 Pro Plus has an advantage in pure autonomy. The Saros 10R compensates with greater cleaning efficiency thanks to its intelligent navigation, completing tasks in less time although with lower total autonomy.
Intelligent Functions
All three robots can overcome obstacles of 20 mm in height, sufficient for most transitions between rooms and small level changes. The Saros 10R specifies capability for simple steps, although the maximum height remains within that range.
An important difference: only the Saros 10R incorporates its own voice assistant, in addition to Alexa and Google Home compatibility that it shares with the other two models. This allows direct interaction with the robot without the need for other intermediary devices.
Multifunction Cleaning Base
The D20 Pro Plus base is limited to auto-emptying the dust bin into a 5-litre bag, the largest of the three. It does not wash or dry mops, nor does it include a detergent tank. It also lacks tray self-cleaning, as it has no washing system.
The L10s Ultra Gen 3 offers a third-generation multifunction base with tray self-cleaning, mop washing with hot water and drying with hot air. It includes a detergent tank to add product during mop washing. The dust bag has a capacity of 3.2 litres, whilst the clean and dirty water tanks reach 4.5 and 4 litres respectively. Dreame offers an optional plumbing connection kit that must be purchased separately.
The Saros 10R is equipped with a 2.0 multifunction base with tray self-cleaning, washing with hot water and drying with hot air. Its detergent tank allows automatic product dosing. The dust bag is the smallest at 2.5 litres, and the clean and dirty water tanks have 4 and 3 litres. This smaller capacity may require more frequent emptying in large homes.
Dimensions
The diameter barely varies: 350 mm on the Dreame models and 353 mm on the Saros 10R. The key difference lies in height. The Saros 10R measures only 79.8 mm, allowing it to access under low furniture, sofas and beds where the other two cannot enter. The D20 Pro Plus reaches 96.8 mm and the L10s Ultra Gen 3 reaches 97 mm.
Regarding the bases, the D20 Pro Plus is the most compact: 298 mm wide, 452 mm high and 440 mm deep. The L10s Ultra Gen 3 measures 340 x 590 x 457 mm, whilst the Saros 10R is the most voluminous at 381 x 488 x 475 mm. It is advisable to measure the available space before deciding, especially if planning to locate the base in confined areas.
Real-World Usage Experience
For large houses, the D20 Pro Plus offers the greatest autonomy with 285 minutes and a 5-litre dust bag that requires fewer changes. However, its basic mopping with static mop and without automatic washing involves more manual maintenance.
In homes with pets, the L10s Ultra Gen 3 and the Saros 10R recognise animals and adjust their behaviour. The D20 Pro Plus and the Saros 10R incorporate anti-tangle brush systems especially useful with long hair. The greater power of the L10s Ultra Gen 3 is advantageous for vacuuming hair embedded in carpets.
For those who prioritise mopping, the Saros 10R stands out with warm water on the floor, dirt detection for automatic re-mopping and the ability to detach mops. The L10s Ultra Gen 3 offers an excellent balance with rotating mops, side extension and complete multifunction base.
If the home has lots of low furniture, the Saros 10R with its 79.8 mm height accesses spaces inaccessible to the other two. Its dual AI camera and recognition of 108 obstacles minimise manual interventions in complex environments.
