Introduction
The Dreame D20 Pro Plus, the Mova E40 Ultra and the Roborock Qrevo S5V are three 2025 offerings that present different strategies within the robot vacuum market. Dreame opts for a model with dual main brush and self-emptying base, whilst Mova and Roborock offer systems with multifunction base that includes mop washing and drying. The Roborock unit maintains its reputation as a global benchmark in reliability, whilst Dreame and its second brand Mova seek to compete with powerful features at more competitive prices.
These models are designed for users seeking automation in daily cleaning. The Dreame D20 Pro Plus is interesting for those who prioritise vacuuming and have less need for intensive mopping. The Mova E40 Ultra stands out for its 19,000 Pa suction power and advanced mopping functions. The Roborock Qrevo S5V maintains the brand's characteristic balance, with a complete and well-integrated system.
Power and Suction
The most striking difference in this section is marked by the Mova E40 Ultra with its 19,000 Pa of suction power. This figure significantly exceeds the 13,000 Pa of the Dreame D20 Pro Plus and the 12,000 Pa of the Roborock Qrevo S5V. In practice, this greater power translates into better capability for thick carpets and floors with ingrained dirt.
The brushing system also varies. The Dreame D20 Pro Plus features a dual HyperStream brush, designed to reduce hair tangles thanks to its single-end anchoring. The Mova E40 Ultra uses a single brush, whilst the Roborock Qrevo S5V is equipped with the DuoDivide system, which pushes hairs towards the central gap to improve suction and minimise tangles.
Regarding the side brush, the Dreame D20 Pro Plus is the only one that incorporates extension to better reach corners. All three models include anti-tangle side brush, but none offers side brush lifting during mopping. Neither can any of the three lift the main brush when mopping, which may be relevant if you're looking to prevent the brush from getting wet during mopping.
Mopping
Here the differences are substantial. The Dreame D20 Pro Plus uses a static mop without edge extension or lifting capability. This limits its mopping effectiveness, especially on skirting boards and corners. As it doesn't have a multifunction base, the mops are neither washed nor dried automatically, which requires more frequent manual maintenance.
The Mova E40 Ultra and the Roborock Qrevo S5V, on the other hand, are equipped with two rotating mops that extend to reach edges. The Mova lifts them up to 10.5 mm when detecting carpets, whilst the Roborock reaches 10 mm. Both systems allow the robot to mop more effectively and avoid wetting unwanted surfaces.
The multifunction base of the Mova E40 Ultra and the Roborock Qrevo S5V washes the mops with hot water and dries them with hot air. This process is fundamental for keeping the mops clean during the mopping session and preventing bad odours when finished. The Mova optionally includes a detergent tank that is purchased separately, something that may be useful for users seeking extra cleaning, although it's not a determining factor in the comparison.
None of the three models allows automatic mop removal at the base to perform vacuuming only, nor does it detect dirt on mops or floor to adjust cleaning.
Navigation System
All three robots use LiDAR turret to map the home and plan efficient routes. All incorporate obstacle avoidance and are compatible with external voice assistants such as Alexa or Google Home.
The Dreame D20 Pro Plus and the Mova E40 Ultra feature a front 3D laser sensor, which improves detection of low objects and helps avoid collisions. The Roborock Qrevo S5V does without this sensor, although its navigation system remains precise thanks to the brand's accumulated experience in mapping algorithms.
The Mova E40 Ultra adds pet recognition, a function that may be useful in homes with animals, as it allows the robot to identify them and adjust its behaviour. Neither the Dreame nor the Roborock offer this capability. None of the three models incorporates AI camera, night vision LED or remote camera access.
The Mova E40 Ultra integrates CleanGenius, an AI-based intelligent cleaning system. The Roborock Qrevo S5V includes SmartPlan, its own intelligent planning solution. The Dreame D20 Pro Plus does not specify functions of this type.
Battery Life and Battery
The battery capacity is identical in all three models: 5,200 mAh. However, battery life varies considerably. The Dreame D20 Pro Plus reaches 285 minutes of continuous operation, a figure that allows it to cover large homes without the need for intermediate recharging. The Mova E40 Ultra offers 210 minutes, and the Roborock Qrevo S5V remains at 180 minutes.
This difference can be explained by the type of brush and suction power. The Mova, with its 19,000 Pa, consumes more energy. The Dreame, with dual brush and lower power, optimises battery life better. The Roborock balances power and duration, although its battery life is the tightest of the three.
For homes over 150 square metres, the Dreame D20 Pro Plus offers greater margin of safety. In smaller flats, the battery life of the Mova and the Roborock is sufficient.
Smart Functions
All three robots can overcome obstacles up to 20 mm in height, which allows them to navigate cables, small rugs and level differences between rooms without problems. None of the models includes robotic arm or own voice assistant, although all are compatible with Alexa and Google Home.
Multifunction Cleaning Base
The Dreame D20 Pro Plus is limited to self-emptying the dust bin. Its bag has a 5-litre capacity, the most generous of the three, which reduces replacement frequency. It does not have water tanks in the base, as it neither washes nor dries mops.
The Mova E40 Ultra is equipped with a complete multifunction base. It washes the mops with hot water and dries them with hot air. Its clean water tanks reach 4.5 litres, and the dirty water one 4 litres. The dust bag has a 3.2-litre capacity. Optionally, a detergent tank can be added, although this accessory is sold separately and shouldn't be a decisive factor in the choice.
The Roborock Qrevo S5V also includes a multifunction base with mop washing and drying using hot water and air. Its clean water tanks are 4 litres and the dirty water one 3.5 litres. The dust bag has 2.7 litres, the smallest of the three, which means more frequent changes.
None of the three models offers self-cleaning of the washing tray, UV disinfection, automatic mop changing or connection to plumbing.
Dimensions
The diameter of the robots is practically identical: 350 mm on the Dreame and the Mova, 353 mm on the Roborock. The height is also similar, with 96.8 mm on the Dreame, 97 mm on the Mova and 96.5 mm on the Roborock. These measurements allow all three models to slide under most low furniture.
The bases present more variations. The Dreame D20 Pro Plus measures 298 mm wide, 452 mm high and 440 mm deep, being the most compact. The Mova E40 Ultra reaches 340 mm wide, 590.5 mm high and 456.7 mm deep. The Roborock Qrevo S5V measures 340 mm wide, 521 mm high and 487 mm deep. The Mova's greater height is due to its mop washing and drying system, which requires more internal space.
Real-World User Experience
The Dreame D20 Pro Plus works well in large homes where battery life is key. Its 350 ml water tank on the robot allows longer mopping sessions without refills, although the absence of a multifunction base requires manual mop washing. The extendable side brush improves corner cleaning, something the other two don't offer. Its 5-litre dust bag reduces maintenance.
The Mova E40 Ultra stands out in homes with pets and intense dirt thanks to its 19,000 Pa of power. The multifunction base with mop washing and drying guarantees more effective mopping. The extendable mops reach edges better, and the 10.5 mm lift protects carpets. Its 210-minute battery life is sufficient for medium-sized flats.
The Roborock Qrevo S5V offers a balance between power, mopping and reliability. Its DuoDivide system reduces hair tangles, and the multifunction base keeps the mops clean. Although its battery life is tighter, it's suitable for homes up to 120-130 square metres. The brand provides confidence in terms of durability and app support.
Conclusion: Which One to Choose?
Choose the Dreame D20 Pro Plus if you're looking for maximum battery life for large homes, don't need intensive mopping and prefer more spaced-out maintenance thanks to its 5-litre bag.
