Introduction
The Dreame L40 Ultra, the Roborock Qrevo Edge S5A and the Roborock Qrevo S5V represent three advanced solutions in robot vacuum cleaners with multifunctional base. All three models belong to the high-end range of their respective manufacturers, launched between 2024 and 2025, and are designed to offer autonomous cleaning in both vacuuming and mopping.
Dreame opts with the L40 Ultra for particularly comprehensive equipment in sensors and artificial intelligence functions. Roborock presents two options: the Qrevo Edge S5A stands out for its suction power, whilst the Qrevo S5V arrives as a more recent version with some differences in equipment. These proposals are designed for homes seeking total automation of floor maintenance, with bases that wash and dry the mops without manual intervention.
Power and Suction
The most striking difference in this robot vacuum cleaner comparison lies in suction power. The Roborock Qrevo Edge S5A leads with 18,500 Pa, a figure that widely exceeds the 11,000 Pa of the Dreame L40 Ultra and the 12,000 Pa of the Roborock Qrevo S5V. This superiority can make notable differences on medium-pile carpets or in picking up embedded particles.
Regarding the brushing system, the Dreame robot vacuum cleaner mounts a TriCut 3.0 brush that combines bristles with blades to reduce hair tangles. The two Roborock models equip the DuoDivide Antienredos system, designed to push hairs towards the centre and facilitate their suction. All three include anti-tangle side brush.
The Dreame L40 Ultra differs by raising both the main brush and the side brush during mopping, preventing them from touching the wet floor. The Roborock models do not raise these brushes. Additionally, the Roborock Qrevo Edge S5A robot vacuum cleaner features extendable side brush to improve corner cleaning, a function that the Qrevo S5V does not incorporate. The Dreame L40 Ultra also has an extendable side brush.
For homes with pets or people with long hair, it is worth considering that the Dreame overcomes obstacles up to 22 mm, compared to 20 mm of the Roborock models, which facilitates moving between rooms with small level differences.
Mopping
All three robots employ a two rotating mops system. The Dreame L40 Ultra and the Roborock Qrevo Edge S5A extend the mops to better reach edges; the Qrevo S5V also incorporates mop extension. The Dreame additionally adds the Roboswing system, which performs a lateral movement to introduce the mop under furniture overhangs.
Mop lifting reaches 10.5 mm on the Dreame L40 Ultra, whilst the two Roborock models lift 10 mm. This function allows the robot to move over carpets without wetting them during mopping. All three models mop with cold water.
An exclusive advantage of the Dreame L40 Ultra is the automatic removal of the mops at the base, allowing vacuum-only sessions to be performed without the need to remove them manually. Neither of the Roborock models offers this possibility.
Both the Dreame L40 Ultra and the Roborock Qrevo Edge S5A detect dirt on the mops and on the floor, adjusting cleaning as necessary. The Roborock Qrevo S5V does not include these detection functions, which limits its ability to adapt mopping to dirtier areas.
Navigation System
Here appears one of the most marked differences between the Dreame robot vacuum cleaner and the Roborock options. The Dreame L40 Ultra integrates dual AI camera, front 3D laser sensor and LED for night vision. It recognises up to 100 types of obstacles, identifies pets and detects curtains to avoid tangles. Additionally, it allows remote access to the camera from the mobile application.
The Roborock Qrevo Edge S5A and Qrevo S5V use LiDAR turret with obstacle avoidance, but do not incorporate AI camera or 3D laser sensor. Neither do they offer remote camera access or front LED. This simpler configuration may prove sufficient for tidy homes, although the Dreame provides greater precision in complex environments with small objects or pets.
The Dreame L40 Ultra employs the AI Sage 11.0 algorithm with CleanGenius, whilst the Roborock Qrevo Edge S5A uses RR Mason 11.0 with SmartPlan. The Qrevo S5V also includes SmartPlan, although its algorithm is not specified. In practice, all offer precise mapping and intelligent route planning.
Autonomy and Battery
All three robots mount 5,200 mAh batteries. The Dreame L40 Ultra declares 194 minutes of autonomy, exceeding the 180 minutes of both Roborock models. This difference can be explained by the lower suction power of the Dreame, which consumes less energy.
For medium or large-sized homes, any of the three offers sufficient autonomy to complete cleaning in a single session. If the battery runs out, the robots automatically return to the base, recharge as necessary and resume cleaning where they left off.
Smart Functions
The Dreame L40 Ultra includes its own voice assistant, in addition to compatibility with Alexa and Google Home. The Roborock models are only compatible with external assistants. This function allows the Dreame to respond with its own voice to commands or report on cleaning status.
The pet recognition of the Dreame L40 Ultra proves useful in homes with animals, allowing automatic exclusion zones to be created around feeders or beds. Curtain detection prevents the robot from tangling in long fabrics. These functions are not present in the Roborock models.
Multifunctional Cleaning Base
All three bases perform auto-emptying of the dust bin, mop washing with hot water and drying with hot air. This configuration ensures that the mops are cleaned during mopping and dried upon finishing, avoiding bad odours.
The Dreame L40 Ultra and the Roborock Qrevo Edge S5A incorporate second-generation washing tray self-cleaning, a function that the Qrevo S5V does not include. This reduces manual maintenance of the base.
Only the Dreame L40 Ultra has a detergent tank in the base, dispensing product during mop washing. The Roborock models do not offer this possibility. Additionally, the Dreame features an optional pipe connection kit, which must be purchased separately and is not included as standard.
In tank capacities, the Dreame L40 Ultra has the advantage: 3.2-litre dust bag compared to 2.7 litres in the Roborock models; 4.5-litre clean water tank compared to 4 litres; and 4-litre dirty water tank compared to 3.5 litres. These differences translate into greater autonomy between emptying and refilling.
Dimensions
The Dreame L40 Ultra measures 350 mm in diameter and 103.8 mm in height. The Roborock Qrevo Edge S5A has 352 mm in diameter and 98 mm in height. The Roborock Qrevo S5V reaches 353 mm in diameter and 96.5 mm in height. This height difference can prove relevant: the Qrevo S5V fits under furniture with 96.5 mm of clearance, whilst the Dreame requires at least 103.8 mm.
The robot's tanks vary slightly: the Dreame carries 300 ml of dust, whilst the Roborock models carry 325 ml and 330 ml respectively. All include an 80 ml water tank in the robot.
Regarding the bases, the Dreame L40 Ultra is the tallest at 590.5 mm, compared to 521 mm of both Roborock models. However, the Dreame is less deep: 456.7 mm compared to 487 mm. It is advisable to measure the available space before deciding, especially if the base will be located under furniture or in a tight space.
Real-world experience
For homes with pets, the Dreame L40 Ultra offers clear advantages: specific animal recognition, dual AI camera, greater tank capacity and automatic mop removal for vacuum-only sessions when mopping is not desired. The TriCut 3.0 brush reduces hair tangles, although the Roborock DuoDivide systems also work well in this aspect.
In homes with thick carpets or very dirty floors, the 18,500 Pa power of the Roborock Qrevo Edge S5A makes a difference. This figure widely exceeds the rest and guarantees better pickup of embedded particles. The Dreame L40 Ultra compensates with greater intelligence in navigation and obstacle adaptation.
For those seeking maximum automation and minimum maintenance, the Dreame L40 Ultra stands out for its detergent tank, greater water and dust capacity, and tray self-cleaning 2.0. The Roborock Qrevo Edge S5A also includes tray self-cleaning, but the Qrevo S5V does not, which implies more manual intervention.
If the home has low furniture or tight spaces, the Roborock Qrevo S5V with 96.5 mm in height accesses better than the Dreame L40 Ultra with 103.8 mm. This difference can determine whether or not the robot cleans under beds, sofas or wardrobes.
The dirt detection on mops and floor of the Dreame L40 Ultra and the Roborock Qrevo Edge S5A improves mopping results, rewashing dirtier areas. The Qrevo S5V lacks this function, which can be particularly noticeable in kitchens or entrances with greater dirt accumulation.
