Introduction
We're looking at three high-end robot vacuum cleaners launched in 2025 that represent the best from each manufacturer: the Dreame L40s Pro Ultra, the Roborock Qrevo S5V and the Xiaomi Robot Vacuum 5 Pro. All three units feature a complete multifunctional base station, capable of washing and drying the mops automatically, which guarantees effective mopping without manual intervention.
These models are designed for users seeking total automation in home cleaning. They share advanced features such as laser navigation, dual rotating mop mopping systems and high-capacity batteries (5,200 mAh in all three cases). However, differences in suction power, artificial intelligence navigation systems and specific functions mark important distinctions between them.
Power and Suction
Suction power marks significant differences. The Xiaomi Robot Vacuum 5 Pro reaches 20,000 Pa, the highest figure of the three, whilst the Dreame L40s Pro Ultra offers 19,000 Pa. The Roborock Qrevo S5V remains at 12,000 Pa, a more modest power that Roborock compensates for with its DuoDivide brushing system, specifically designed to push hair and dirt towards the central suction gap avoiding tangles.
The Dreame opts for a dual main brush, technology that improves pick-up in a single pass. The Xiaomi features the TriCut 3.0 system, which combines bristles with blades to cut tangled hair. All three models include an anti-tangle side brush.
Regarding brush lifting, the Dreame stands out by raising both the main brush and the side brush during mopping, preventing them from interfering with the mops. The Xiaomi raises the main brush but not the side one, and the Roborock doesn't raise either. This function is practical when mopping, as it prevents the brushes from dragging wet dirt.
Both the Dreame and the Xiaomi feature an extendable side brush to improve corner cleaning. The Roborock does without this feature.
Mopping
All three robots use a dual rotating mop system, currently the most effective for domestic mopping. All extend the mops to better reach edges, although the Dreame adds the Roboswing system, which performs a lateral movement to introduce the mop under furniture and overhangs.
Mop lifting varies slightly: the Xiaomi reaches 15 mm, the Dreame 10.5 mm and the Roborock 10 mm. These differences allow the robot to pass over thin carpets without wetting them during mopping mode.
An exclusive function of the Dreame L40s Pro Ultra is automatic mop detachment at the base station. This means that when you only need to vacuum, the robot leaves the mops at the station and works without dragging them, something the other two models cannot do.
In dirt detection, both the Dreame and the Xiaomi incorporate sensors to identify dirtier areas on the floor and on the mops themselves, adjusting mopping intensity or going over the area again. The Roborock doesn't have this technology.
All three base stations wash the mops with hot water, which improves the removal of grease and adhered dirt. Drying is also carried out with hot air in all three cases, reducing times and preventing bad odours. However, only the Dreame and the Xiaomi include self-cleaning of the washing tray, with the Dreame's being third generation. The Roborock requires manual cleaning of this area.
Navigation System
Here we find notable differences. The Dreame L40s Pro Ultra features a dual camera with artificial intelligence, front 3D laser sensor and recognises up to 180 different types of obstacles. Additionally, it specifically identifies pets and curtains, adjusting its behaviour accordingly. It includes LED for night vision and allows remote access to the camera from your mobile.
The Xiaomi Robot Vacuum 5 Pro also integrates an AI camera, 3D laser sensor, night LED and remote camera access, with the ability to recognise up to 200 obstacles. However, it doesn't specify pet or curtain recognition.
The Roborock Qrevo S5V does without an AI camera, 3D laser sensor, LED and remote access. Its navigation is based on the traditional LiDAR system with basic obstacle avoidance. For many homes this navigation is sufficient, but it lacks the intelligent recognition advantages offered by the other two.
All three use a LiDAR turret to map the home, although the Xiaomi incorporates retractable LiDAR, which contributes to its lower overall height.
Battery Life and Battery
Battery capacity is identical in all three models: 5,200 mAh. However, actual battery life differs considerably. The Dreame L40s Pro Ultra achieves 220 minutes of continuous use, sufficient for large homes. The Roborock Qrevo S5V reaches 180 minutes, whilst the Xiaomi remains at 140 minutes.
This difference can be explained by the consumption generated by the Xiaomi's higher suction power and the Dreame's optimised energy management. In practice, 140 minutes is still sufficient for most homes, but in large properties or complete cleans with intensive mopping, the Dreame's battery life makes a difference.
Smart Functions
All three robots can overcome obstacles of 20 mm in height, except the Dreame which specifies capacity for simple steps without detailing the exact measurement. This function allows them to navigate door thresholds and small level changes without getting stuck.
The Dreame L40s Pro Ultra incorporates its own voice assistant, in addition to compatibility with Alexa and Google Home. The other two models only work with external assistants.
Multifunctional Cleaning Base Station
All three base stations perform auto-emptying of the dust bin, mop washing with hot water and drying with hot air. The differences lie in the details.
The Dreame has the largest dust bag: 3.2 litres, compared to 2.7 for the Roborock and 2.5 for the Xiaomi. It also leads in water tanks: 4.5 litres of clean water and 4 litres of dirty water. The Roborock has 4 litres of clean water and 3.5 of dirty, whilst the Xiaomi sits at 4 and 3.8 litres respectively.
An exclusive feature of the Dreame is the detergent tank integrated into the base station, which dispenses product during mop washing. The other two models lack this option.
The Dreame also offers an optional kit for connection to water pipes, which must be purchased separately. Although it doesn't come integrated as standard, it can be convenient for those seeking to completely forget about manual filling of tanks.
Dimensions
The diameter is practically identical: 350 mm on the Dreame and Xiaomi, 353 mm on the Roborock. The important difference is in height. The Xiaomi Robot Vacuum 5 Pro measures only 88 mm tall, which allows it to slip under low furniture more easily. The Roborock reaches 96.5 mm and the Dreame 103.8 mm.
For homes with low sofas, beds with little clearance from the floor or tight kitchen units, those millimetres can make the difference between the robot accessing those areas to clean or not.
The base stations also vary in size. The Xiaomi's is the widest (360 mm) but the Dreame's is the tallest (590.5 mm). The Roborock has the most compact base station in height (521 mm) but the deepest (487 mm). It's advisable to measure the available space before deciding.
Real-world user experience
For large homes, the Dreame L40s Pro Ultra offers the best combination of extended battery life, large tank capacity and advanced functions such as automatic mop detachment. Its power of 19,000 Pa is more than sufficient for any type of flooring.
If you live with pets, the Dreame stands out again thanks to its specific animal recognition and dual AI camera, which avoids accidents with small objects or waste. The Roborock's brush system, the DuoDivide, also works exceptionally well with animal hair.
The Xiaomi Robot Vacuum 5 Pro is ideal for those with low furniture who need the robot to access difficult areas. Its height of 88 mm and maximum power of 20,000 Pa make it a powerful and compact option, although its more limited battery life may require recharging in large homes.
The Roborock Qrevo S5V opts for the brand's proven reliability, an exclusive brushing system and a compact base station. Although it lacks an AI camera and some advanced functions, its traditional LiDAR navigation works perfectly in most homes. It's the simplest option of the three, without sacrificing essential features.
Conclusion: Which one to choose?
