Introduction
The Dreame D20 and the Roborock Qrevo S5V represent two different philosophies within the 2025 launches in robot vacuum cleaners. Whilst the Dreame model opts for simplicity and autonomy with a conventional charging base, the Roborock unit integrates a complete multifunction base that completely transforms the mopping experience. Both share the same launch year, but their features place them in clearly differentiated segments.
The Dreame D20 stands out for incorporating a generous 700 ml dustbin in the robot itself and a 350 ml water tank, dimensions that grant it great autonomy between manual emptying. The Roborock Qrevo S5V, on the other hand, reduces these internal bins (330 ml dust and barely 80 ml water) because its base takes care of automatic waste management and mop washing.
Power and Suction
The suction power of the Dreame D20 stands at 13000 Pa, slightly exceeding the 12000 Pa of the Roborock Qrevo S5V. This 1000 Pa difference can be particularly noticeable on medium-pile carpets or when picking up embedded particles, although in daily practice both offer more than sufficient performance for most homes.
As for the main brush, the Dreame D20 features a dual anti-tangle brush system, whilst the Roborock Qrevo S5V mounts the DuoDivide design, also anti-tangle. Both systems come fitted as standard and seek to minimise the accumulation of long pet hair and human hair, something fundamental in homes with pets or people with long hair.
The side brush presents a relevant difference: the Roborock Qrevo S5V's incorporates anti-tangle technology, which the Dreame D20 does not include. This facilitates maintenance on the Roborock model, as the side brush is usually the point where hair and fibres accumulate most. Neither model features a liftable or extendable side brush.
Mopping
Here we find the most substantial difference in this robot vacuum cleaner comparison. The Dreame D20 uses a static mop without lift, which means that during vacuuming the mop remains in contact with the floor. This system is basic and requires manually removing the mop if we want to vacuum without dragging it across carpets or rugs.
The Roborock Qrevo S5V radically changes the scenario with its two rotating mops that can lift 10 mm when the robot detects carpets or when we want to vacuum without mopping. Additionally, it integrates the FlexiArm system that extends one of the mops to better reach skirting boards and corners, a function that makes real differences in the mopping finish.
The Roborock Qrevo S5V's base washes the mops with cold water during cleaning and subsequently dries them with hot air at 45°C. This means the robot periodically returns to the base to wash the dirty mops and continue mopping with clean mops, something that completely transforms the quality of mopping compared to a static mop that progressively gets dirty. The Dreame D20 lacks these functions: it neither washes nor dries mops, because its base is only for charging.
Navigation System
Both robots mount LIDAR 3.0 turret to map the home and plan efficient routes. Both include obstacle avoidance, but with different nuances in implementation. The Dreame D20 incorporates a front 3D laser sensor that complements the LIDAR to detect low or short objects, something the Roborock Qrevo S5V does not have.
Neither integrates a camera with artificial intelligence, nor specific pet recognition, nor curtain detection, nor remote camera access. They also do not include front LED for night vision. Navigation is based mainly on LIDAR and avoidance sensors.
The Roborock Qrevo S5V adds SmartPlan intelligent cleaning, a system that automatically optimises routes and adjusts parameters according to floor type and detected dirt level. The Dreame D20 does not have this artificial intelligence function.
Autonomy and Battery
Both robots mount 5200 mAh batteries, a generous capacity that guarantees sufficient autonomy for medium-large sized homes. The Roborock Qrevo S5V specifies 180 minutes of autonomy, data that the Dreame D20 does not detail in its technical specifications.
In practice, autonomy management differs quite a bit between both models. The Dreame D20, having large internal bins (700 ml dust and 350 ml water), can complete extensive cleaning without needing to return to the base, although afterwards it will be necessary to empty and refill manually. The Roborock Qrevo S5V, with smaller bins (330 ml and 80 ml), depends on its multifunction base to manage waste and water, but does so automatically.
Smart Functions
Both robots can overcome obstacles up to 20 mm in height, which allows them to navigate without problems over medium-thickness carpets, thick cables or small level differences between rooms. Neither incorporates a robotic arm nor its own voice assistant.
Multifunction Cleaning Base
The Dreame D20's base is a simple charging base without additional functions. There is no dust auto-emptying, nor mop washing, nor water tanks. Maintenance is completely manual: the robot's 700 ml dustbin must be emptied and the 350 ml water tank refilled when necessary.
The Roborock Qrevo S5V integrates a complete multifunction base with a 2.7 litre dust bag that automatically collects waste from the robot. The water tanks are 4 litres for clean water and 3.5 litres for dirty water, dimensions that allow several mopping sessions without manual intervention. The base washes the mops with cold water and dries them with hot air at 45°C, preventing bad odours and bacterial proliferation.
Neither base includes auto-cleaning of the washing tray, UV disinfection, detergent tank, nor connection to plumbing (nor optional kit). They also do not have automatic mop changing.
Dimensions
The Dreame D20 measures 350 mm in diameter and 96.8 mm in height, whilst the Roborock Qrevo S5V has 353 mm in diameter and 96.5 mm in height. The differences are minimal: barely 3 mm in diameter and 0.3 mm in height. Both robots can slip under furniture with similar clearance.
The bases present much more marked differences. The Dreame D20's base is compact: 126 mm wide, 92.6 mm high and 130 mm deep. The Roborock Qrevo S5V's base, being multifunction, occupies considerably more: 340 mm wide, 521 mm high and 487 mm deep. This should be considered if available space is limited.
Real-World User Experience
The Dreame D20 is ideal for those who prefer a simple robot, without complications, and do not mind taking care of manual maintenance. Its large internal bins (700 ml dust and 350 ml water) grant it autonomy to clean medium-sized homes without interruptions. The 13000 Pa power guarantees good vacuuming results, and the dual anti-tangle brush facilitates maintenance in homes with pets. The front 3D laser sensor adds a bonus in detecting low obstacles.
The Dreame D20's mopping, however, is limited by its static mop without lift. It works for light maintenance of hard floors, but does not reach the level of a rotating mop system with automatic washing. The mop must be manually removed if we want to vacuum carpets without dragging it.
The Roborock Qrevo S5V offers a much more automated experience. The multifunction base manages dust emptying and mop washing and drying, drastically reducing maintenance. The rotating mops with FlexiArm extension and 10 mm lift provide deep mopping and allow vacuuming carpets without problems. The SmartPlan system automatically optimises cleaning according to floor type.
For homes with pets, the Roborock Qrevo S5V's anti-tangle side brush represents an additional advantage in maintenance. The declared 180 minutes of autonomy covers flats of over 150 m² without problems. The base, mind you, requires space: its 340x521x487 mm dimensions do not go unnoticed.
Conclusion: Which to Choose?
Choose the Dreame D20 if... you are looking for a simple and economical robot vacuum cleaner, you do not mind manual maintenance, you value having large bins in the robot itself for greater autonomy between emptying, you prioritise suction power (13000 Pa) and you have little space for the base. It is a good option for small or medium-sized homes without thick carpets, where basic mopping with a static mop is sufficient for daily maintenance of hard floors.
Choose the Roborock Qrevo S5V if... you want to forget about maintenance thanks to the multifunction base with auto-emptying, mop washing and drying, you need quality mopping with rotating mops that extend to reach edges and lift to vacuum carpets, you value SmartPlan intelligent cleaning that automatically optimises routes, you have medium or large homes (up to 150-180 m²), you live with pets and appreciate the anti-tangle side brush, and you have space for a base of considerable dimensions. It is the most complete option in this 2025 robot vacuum cleaner comparison.
