Introduction
The Dreame L50 Pro Ultra, the Mova P50s Ultra and the Roborock Qrevo Slim represent three distinct propositions within the robot vacuum cleaner segment with multifunction base. The first two arrive in 2025 as offerings from Dreame and its sister brand Mova, whilst the Roborock model dates from 2024. All include advanced navigation systems, mopping with rotating mops and bases that automatically wash and dry the mops, which places them in the high-end market segment.
The Dreame L50 Pro Ultra stands out for its suction power of 19,500 Pa and a height of 89 mm. The Mova P50s Ultra raises the power to 24,000 Pa and reduces the height to 82.5 mm. The Roborock Qrevo Slim, with its 82 mm height and 11,000 Pa, presents itself as the most compact option although less powerful. The choice will depend on the type of home, the presence of pets and specific cleaning needs.
Power and Suction
The most notable difference in this robot vacuum cleaner comparison lies in the suction power. The Mova P50s Ultra reaches 24,000 Pa, a figure that positions it as the most powerful of the trio. The Dreame L50 Pro Ultra remains at 19,500 Pa, still a very competitive figure. The Roborock Qrevo Slim, with 11,000 Pa, offers less raw power but maintains sufficient performance for most homes.
All three robots feature a dual HyperStream anti-tangle main brush, a design that minimises hair tangles and facilitates maintenance. This system is especially useful in homes with pets. Additionally, all three models lift the main brush during mopping to prevent it from getting wet.
Regarding the side brush, the Dreame L50 Pro Ultra and the Mova P50s Ultra incorporate extendable, liftable and anti-tangle versions. The Roborock Qrevo Slim also features an extendable side brush, but it cannot be lifted nor does it include anti-tangle technology. This may result in greater accumulation of wrapped hair on the Roborock model's side brush, especially if you live with long-haired animals.
Mopping
The mopping system is similar across all three units: two rotating mops that extend to reach the edges. The Dreame L50 Pro Ultra and the Mova P50s Ultra also include the Roboswing system, which allows the robot to make lateral movements to get the mop under furniture or protrusions. The Roborock Qrevo Slim does not have this function.
Mop lifting is practically identical: 10.5 mm on the Dreame and Mova models, 10 mm on the Roborock. Sufficient to pass over thin carpets without wetting them. All three wash the mops with hot water in the base and dry them with hot air, which helps eliminate bacteria and prevent bad odours.
An important difference: the Dreame L50 Pro Ultra and the Mova P50s Ultra can automatically remove the mops at the base when you only want to vacuum, without mopping. The Roborock Qrevo Slim does not offer this functionality, which requires manually removing the mops if you prefer a vacuum-only session. All detect dirt both on the mops and on the floor to adjust cleaning.
Navigation System
Each robot uses its own navigation system. The Dreame L50 Pro Ultra features retractable LiDAR, the Mova P50s Ultra employs FlashPulse and the Roborock Qrevo Slim relies on StarSight 1.0. All three integrate dual camera with artificial intelligence, front 3D laser sensor and LED for night vision.
The number of recognised obstacles varies significantly. The Mova P50s Ultra leads with 200 identifiable objects, followed by the Dreame L50 Pro Ultra with 180 and the Roborock Qrevo Slim with 73. In practice, this means that the Dreame and Mova models can avoid elements such as toys, cables or slippers with greater precision.
The Dreame L50 Pro Ultra and the Mova P50s Ultra detect curtains and adjust their behaviour to avoid getting tangled in them. The Roborock Qrevo Slim lacks this specific function. All three recognise pets and allow remote access to the camera to monitor the home from your mobile.
The Dreame L50 Pro Ultra's processor is the AI Sage 13.0, whilst the Roborock Qrevo Slim uses the RR Mason 11.0. The Mova P50s Ultra's chip is not specified. Dreame and Mova include AI stain recognition, a function that Roborock does not offer, which can make a difference in homes with young children or pets prone to accidents.
Autonomy and Battery
The Dreame L50 Pro Ultra and the Mova P50s Ultra share a 6,400 mAh battery. Dreame declares 200 minutes of autonomy, data that Mova does not specify. The Roborock Qrevo Slim features a 5,200 mAh battery with 180 minutes of autonomy.
For large homes, the greater battery capacity of the Dreame and Mova models represents a clear advantage. They can complete longer cleaning sessions without needing to recharge, which is especially useful in houses of more than 150 square metres or with complex layouts.
Smart Functions
All three robots include their own voice assistant and compatibility with Alexa and Google Home. The ability to overcome steps is superior in the Dreame L50 Pro Ultra and the Mova P50s Ultra, which can overcome simple steps without specifying exact height. The Roborock Qrevo Slim overcomes obstacles up to 20 mm.
None of the three units incorporates a robotic arm, a function that is beginning to appear in very high-end models to pick up small objects from the floor.
Multifunction Cleaning Base
All three bases automatically empty the dust bin, wash the mops with hot water and dry them with hot air. The difference lies in the details. The Dreame L50 Pro Ultra and the Mova P50s Ultra feature third-generation tray self-cleaning, whilst the Roborock Qrevo Slim uses version 1.0. This may result in less manual maintenance on the Dreame and Mova models.
The Mova P50s Ultra is the only one that includes UV disinfection in the base, adding an extra layer of hygiene to mop washing. The Dreame L50 Pro Ultra and the Mova P50s Ultra have a detergent tank that is automatically dispensed during mop washing. The Roborock Qrevo Slim does not include this function, which means cleaning only with water.
The dust bag capacity is greater in the Dreame and Mova models: 3.2 litres compared to the Roborock's 2.7 litres. Regarding water tanks, the Dreame L50 Pro Ultra offers 4.5 litres of clean water and 4 litres of dirty water. The Mova P50s Ultra has 4 litres of clean water and 3.5 of dirty water. The Roborock Qrevo Slim remains at 4 litres of clean water and 3.5 of dirty water.
The Dreame L50 Pro Ultra is the only one that offers an optional plumbing connection kit, an accessory that is purchased separately and allows automating water filling and emptying. Useful for those seeking maximum autonomy, although it is not a determining feature given that it requires installation and additional purchase.
Dimensions
The robot's height marks an important functional difference. The Roborock Qrevo Slim measures 82 mm, the Mova P50s Ultra 82.5 mm and the Dreame L50 Pro Ultra 89 mm. Those 7 mm of difference between the Roborock and the Dreame can determine whether or not the robot passes under certain low furniture, sofas or beds.
The diameter is practically identical: 350 mm in Dreame and Mova, 353 mm in Roborock. The robot's internal tanks also vary: the Dreame L50 Pro Ultra carries 395 ml of dust and 80 ml of water, the Mova P50s Ultra 300 ml of dust and 80 ml of water, and the Roborock Qrevo Slim 220 ml of dust and 72 ml of water. Greater capacity means fewer interruptions in very large homes.
The bases present notable differences. The Mova P50s Ultra's is the widest (420 mm) but also the least tall (470 mm). The bases of the Dreame L50 Pro Ultra and the Roborock Qrevo Slim measure 340 mm wide, although the former reaches 590.5 mm in height compared to the Roborock's 521 mm. It is advisable to measure the available space before deciding.
Real-world user experience
For large homes, the Dreame L50 Pro Ultra and the Mova P50s Ultra start with an advantage thanks to their larger 6,400 mAh battery and more generous tanks. The Dreame's 200-minute autonomy allows covering large surfaces without intermediate recharges.
If you live with pets, all three models include an anti-tangle main brush, but the Dreame L50 Pro Ultra and the Mova P50s Ultra add an anti-tangle side brush, which reduces maintenance. The Mova P50s Ultra's greater power (24,000 Pa) can make a difference on carpets where hair accumulates.
For those seeking to pass under low furniture, the Roborock Qrevo Slim and the Mova P50s Ultra are the most compact options at 82 mm and 82.5 mm respectively. The Dreame L50 Pro Ultra, at 89 mm, may have limitations with very low sofas or beds with little height.
The automatic mop removal of the Dreame L50 Pro Ultra and the Mova P50s Ultra facilitates alternating between vacuuming and mopping sessions without manual intervention. The detergent tank in both also improves mopping quality compared to the Roborock Qrevo Slim, which only mops with water.
Conclusion: Which to choose?
Choose the Dreame L50 Pro Ultra if you seek a balance between power, autonomy and advanced functions. Its 6,400 mAh battery and 200-minute autonomy make it ideal for large homes. The detergent tank and automatic mop removal provide convenience. The optional plumbing connection kit may interest those wanting total automation, although it is not essential. The greater height (89 mm) may limit its access under certain furniture.
Choose the Mova P50s Ultra if you prioritise maximum suction power (24,000 Pa) and want the lowest height without sacrificing a 6,400 mAh battery. UV disinfection in the base adds a hygiene bonus. Recognition of 200 obstacles and curtain detection improve navigation. It is the most complete option for homes with pets and the need to pass under low furniture. Its base is the widest (420 mm), an aspect to consider if space is limited.
Choose the Roborock Qrevo Slim if you value the reference brand in the sector and need the lowest robot (82 mm) to access under furniture. With 11,000 Pa it offers sufficient power for most homes, although inferior to the others
