Introduction
Choosing between the Dreame L10s Ultra Gen 2 and the Roborock Q7 L5 or BF means deciding between two completely different philosophies of automated cleaning. The Dreame model, launched in 2024, represents a commitment to a complete multifunctional base that manages practically all robot maintenance. In contrast, the Roborock Q7 L5 or BF from 2025 opts for a more compact and minimalist design, without a self-emptying base or automatic mop washing system.
We're talking about devices designed for users with radically different needs. The Dreame seeks maximum autonomy in homes where not having to intervene in the cleaning process for weeks is valued. The Roborock, more traditional in its concept, is aimed at those who prefer more direct maintenance or have small spaces where a large base would be intrusive.
Power and Suction
The Dreame L10s Ultra Gen 2 delivers 10,000 Pa of suction, a figure that exceeds the Roborock Q7 L5 or BF by 2,000 Pa. This difference can be particularly noticeable on carpets or when there's pet hair embedded in textiles. Both devices overcome obstacles up to 20 mm in height, sufficient capacity for transitions between rooms or small level changes.
Regarding brushing, the Dreame mounts a simple brush whilst the Roborock uses a bristle brush. Neither offers advanced anti-tangle technologies in the main brush, something to consider if you live with long-haired pets. They also don't incorporate extendable or liftable side brushes, maintaining more conventional designs in this area.
The real difference in suction is determined by the combination of raw power and battery. With 5,200 mAh, the Dreame can maintain cleaning cycles of up to 240 minutes, whilst the Roborock is equipped with a 3,200 mAh battery without specific declared autonomy data.
Mopping
Here we find the most significant gap between both models. The Dreame L10s Ultra Gen 2 integrates two rotating mops with lateral extension through the Roboswing system, which allows better reach to edges and gets the mop under furniture overhangs. Additionally, it lifts the mops up to 10.5 mm when it detects carpets or when returning over already mopped areas.
The Roborock Q7 L5 or BF mounts a static mop without lifting or extension capability. In practice, this means that the Roborock robot cannot avoid wetting carpets or optimise mopping in corners. Its 270 ml water tank exceeds the Dreame's, which has 80 ml, but this advantage is relativised because the Dreame constantly returns to its base to refill water during the mopping process.
The Dreame's base washes the mops with cold water and dries them with hot air after each session, eliminating the need to touch them manually. It incorporates 4.5-litre tanks for clean water and 4 litres for dirty water, plus a compartment for detergent. The Roborock lacks all this system, requiring the user to wash the mop by hand after each use and manually refill the robot's small tank.
Navigation System
Both robots employ a 3D LiDAR turret to map the environment and plan efficient routes. However, the Dreame adds a front 3D laser sensor that allows it to detect and avoid obstacles in real time. This system recognises pets and adjusts its behaviour to avoid disturbing them during cleaning.
The Roborock Q7 L5 or BF does not have obstacle avoidance, which means it relies exclusively on the upper LiDAR and basic contact sensors. In homes with many objects on the floor or with pets, this can translate into more frequent interruptions or the need to better prepare the space before each clean.
Neither incorporates a front camera with remote access or LED for night vision. The Dreame includes its CleanGenius AI-powered intelligent cleaning system, functionality absent in the Roborock.
Autonomy and Battery
The 5,200 mAh battery of the Dreame L10s Ultra Gen 2 offers 240 minutes of continuous operation, sufficient to cover large homes in a single session. The Roborock Q7 L5 or BF is equipped with 3,200 mAh, a notably lower capacity that limits its autonomy, although the exact operating time is not specified.
This difference is decisive in large homes. The Dreame can complete extensive cleans without needing to recharge mid-cycle, whilst the Roborock will probably need intermediate pauses in surfaces exceeding 80-100 square metres, depending on the type of cleaning and the power mode selected.
Smart Features
The Dreame L10s Ultra Gen 2 integrates its CleanGenius system, which automatically adjusts cleaning parameters according to the type of dirt and surface detected. Pet recognition allows the robot to modulate its behaviour to avoid frightening animals during work.
The Roborock Q7 L5 or BF dispenses with these artificial intelligence-based functionalities, maintaining a more direct approach where the user manually configures cleaning parameters. Both robots are compatible with external voice assistants such as Alexa or Google Home, facilitating control by voice commands.
Multifunctional Cleaning Base
The most evident difference between these devices lies in their bases. The Dreame L10s Ultra Gen 2 incorporates a complete station that manages self-emptying of the dust container into a 3.2-litre bag, washes the mops with cold water during and after each session, and dries them with hot air to prevent bad odours. The 4.5 and 4-litre tanks for clean and dirty water allow several weeks of operation without intervention.
Additionally, it has a detergent compartment that is automatically dosed during mop washing. There is an optional plumbing connection kit that must be purchased separately, although it doesn't come integrated as standard. This base measures 340 mm wide, 590.5 mm high and 456.7 mm deep, occupying considerable space.
The Roborock Q7 L5 or BF only includes a charging base of 160 x 101 x 70 mm, practically imperceptible in any corner. It doesn't perform self-emptying, washing or drying, requiring complete manual maintenance: emptying the robot's 400 ml dust container, washing the mop by hand and refilling the 270 ml water tank before each mopping.
Dimensions
The Dreame L10s Ultra Gen 2 has a 350 mm diameter and 97 mm height. The Roborock Q7 L5 or BF measures 325 mm in diameter and 99 mm high. The 2 mm difference in height is practically irrelevant, both fit under most standard furniture. The Dreame's somewhat larger diameter doesn't pose a real problem either in navigating typical domestic spaces.
Where there is an abysmal difference is in the bases. The Dreame's occupies significant volume with its 340 x 590.5 x 456.7 mm, needing dedicated space, ideally in a utility room, storage room or service area. The Roborock's, at barely 160 x 101 x 70 mm, fits in any corner without drawing attention.
Real-world user experience
The Dreame L10s Ultra Gen 2 is designed for users seeking to completely forget about maintenance for weeks. Its base manages dust, mops and water without human intervention. In large homes, the combination of 5,200 mAh battery and 10,000 Pa of suction guarantees complete cleans even on surfaces exceeding 150 square metres. The rotating mops with extension substantially improve mopping on edges and corners.
For homes with pets, the 3D laser sensor and specific animal recognition avoid unnecessary frights. The 10.5 mm mop lift protects carpets during mopping. The robot's 300 ml dust container is less relevant because the base empties it automatically.
The Roborock Q7 L5 or BF is better suited to small or medium flats where space is limited and more traditional maintenance is preferred. Its compact base disappears in any corner. The robot's 400 ml dust container and 270 ml water tank require manual emptying and filling, but in homes up to 70-80 square metres this doesn't represent an excessive burden. The static mop performs well on hard floors without complications, although without the Dreame's advanced features.
The absence of obstacle avoidance in the Roborock requires keeping the floor clearer before each clean. Its 3,200 mAh battery may fall short in large homes, needing intermediate recharges.
Conclusion: Which to choose?
Choose the Dreame L10s Ultra Gen 2 if you're looking for total autonomy and have space for a multifunctional base. Ideal for large homes, households with pets, users who value not touching mops or containers for weeks, and those who prioritise advanced mopping with always-clean mops. Its 10,000 Pa power and 5,200 mAh battery guarantee deep cleans on large surfaces. The investment is justified if time saved on maintenance and mopping quality are priorities.
Choose the Roborock Q7 L5 or BF if you live in a small or medium flat, have little space for bulky bases, prefer direct and simple maintenance, or your budget is tighter. Its compact base and traditional operation are sufficient when the home doesn't exceed 80 square metres and mopping doesn't require advanced features. It works well in homes without pets or with mostly clear floors, where the absence of obstacle avoidance doesn't pose a real problem.
