Introduction
The Mova P50 Ultra, the Roborock QV 35A and the Xiaomi X20 Max represent three well-differentiated propositions within the robot vacuum cleaner market with multifunction base. The first arrives in 2025 as a high-end model with advanced features, whilst the Roborock QV 35A also debuts this year with a more balanced approach. The Xiaomi X20 Max, launched in 2024, completes this robot vacuum cleaner comparison with a proposition that maintains solid characteristics at a more competitive price.
We are looking at three units that not only vacuum, but also mop with rotating mops and feature bases that automate the washing and drying of the mops. The difference lies in the details: suction power, navigation systems, base capacity and specific functions that can make the difference depending on the type of home and the needs of each user.
Power and Suction
Suction power marks the first major difference. The Mova robot vacuum cleaner deploys 19,000 Pa, a figure that places it in the highest range of the market and which more than doubles the 8,000 Pa of the Roborock QV 35A and the Xiaomi X20 Max. In practice, this difference is particularly noticeable on medium or long pile carpets, where the capacity to extract embedded dirt is crucial.
All three models mount main brushes designed to reduce hair tangles. The Mova and the Roborock use SimpliCut-type brushes, whilst the Xiaomi opts for the TriCut 3.0. Both systems combine elements that cut hairs before they become excessively tangled.
Where the Mova P50 Ultra takes clear advantage is in brush lifting. This model can raise the main brush during mopping, preventing it from getting wet and guaranteeing more efficient mopping without dragging dry dirt. Neither the Roborock nor the Xiaomi offer this function. The Mova's side brush also lifts, as well as being extendable to better reach corners. Only the Roborock shares with the Mova the anti-tangle system on the side brush.
Mopping
All three robots mop with two rotating mops, the system that currently offers the best results. The bases wash these mops with hot water and also dry them with hot air, which helps to keep them hygienic and odour-free.
The Mova P50 Ultra incorporates mop extension with Roboswing movement, a system that allows the robot to make a small lateral movement to get the mop under furniture and ledges. The Xiaomi X20 Max has mop extension, but without that specific movement. The Roborock robot vacuum cleaner does not feature extendable mops, which limits its cleaning capacity at the edges.
Regarding mop lifting, the Mova sits slightly above with 10.5 mm compared to the 10 mm of the Roborock QV 35A and the Xiaomi. It may seem a minimal difference, but that extra half millimetre can make the difference when passing over thin carpets without wetting them.
None of the three models automatically removes the mops at the base when you only want to vacuum, nor does it detect dirt on the mops or on the floor to adjust mopping. All mop with cold water in the robot's tank.
Navigation System
All three units use LiDAR turret to map the home and navigate with precision. The Mova P50 Ultra and the Xiaomi X20 Max add a front 3D laser sensor that improves detection of obstacles at ground level. The Roborock QV 35A does not include this additional sensor.
The Mova detects curtains, a useful function to avoid tangles or dragging of light fabrics. This capability is not present in the Roborock or the Xiaomi. None of the three incorporates a camera with artificial intelligence or allows remote access for surveillance.
The Xiaomi X20 Max is the only one that mounts night vision LED, which allows it to navigate better in low light conditions. All three feature intelligent cleaning systems based on AI: CleanGenius on the Mova, SmartPlan on the Roborock, and a proprietary system on the Xiaomi. They do not recognise pets or specific stains using AI.
Autonomy and Battery
All three robots mount 5,200 mAh batteries, a generous capacity that guarantees sufficient autonomy for large homes. The Roborock QV 35A specifies 180 minutes of continuous operation, whilst the Xiaomi X20 Max reaches 120 minutes. The Mova P50 Ultra does not detail this data in the table.
The 60-minute difference between the Roborock and the Xiaomi can be explained by energy management and the suction power employed. In any case, both offer sufficient autonomy to clean large surfaces in a single session, returning to the base only when it is necessary to wash the mops or recharge the battery.
Smart Functions
The Mova P50 Ultra can overcome obstacles up to 22 mm in height, two millimetres more than the Roborock QV 35A and the Xiaomi X20 Max, both limited to 20 mm. This can make the difference with certain thresholds or thick carpets.
All three models are compatible with external voice assistants such as Alexa or Google Home, allowing voice control of basic functions. None incorporates a robotic arm or its own voice assistant.
Multifunction Cleaning Base
All three bases automate the emptying of the dust container, the washing of mops with hot water and drying with hot air. The main difference lies in the self-cleaning of the tray where the mops are washed.
The Mova P50 Ultra incorporates third-generation tray self-cleaning, a system that keeps the washing area clean without manual intervention. Neither the Roborock robot vacuum cleaner nor the Xiaomi offer this function, which implies greater manual maintenance in the long term.
The Mova optionally includes a detergent tank that is purchased separately. Neither the Roborock QV 35A nor the Xiaomi X20 Max contemplate this possibility. None of the three has UV disinfection or integrated connection to water pipes.
The Mova's dust bag reaches 3.2 litres, compared to the Roborock's 2.7 and the Xiaomi's 2.5. This translates into fewer bag changes throughout the year. The clean water tanks are identical at 4 litres, whilst the dirty water varies slightly: 3.5 litres in Mova and Roborock, 3.8 in the Xiaomi.
Dimensions
The Roborock robot vacuum cleaner measures 353 mm in diameter, three millimetres more than the Mova P50 Ultra and the Xiaomi X20 Max, both at 350 mm. The height is practically identical: 97 mm in Mova and Xiaomi, 96.5 mm in the Roborock. These millimetric differences do not significantly affect the ability to pass under furniture.
The bases present different configurations. The Mova's is the widest at 420 mm, but also the most compact in depth at 458 mm. The Roborock measures 340 mm wide, 487 mm deep and 521 mm high. The Xiaomi has 340 mm wide, 420 mm deep and is the tallest at 563 mm. It is advisable to measure the available space before deciding, especially if you want to place the base in a specific gap.
Real-world experience
For large homes, the Roborock QV 35A offers the clearest autonomy with 180 minutes specified. The Xiaomi X20 Max, with 120 minutes, may require intermediate recharges on surfaces exceeding 100 square metres. The Mova does not detail autonomy, although its 5,200 mAh battery suggests similar performance to the Roborock.
If you live with pets, the Mova's 19,000 Pa power makes a difference on carpets where hair accumulates. All three have anti-tangle brushes, but the superior suction capacity facilitates the extraction of embedded hair. The Mova's 3.2-litre bag also reduces the frequency of changes when there is a lot of hair.
For those seeking minimum maintenance, the Mova P50 Ultra's tray self-cleaning reduces manual tasks. The Roborock and the Xiaomi require periodic cleaning of the mop washing tray. The possibility of adding detergent in the Mova may also be interesting, although it is an optional accessory.
In homes with many low furniture pieces and complicated corners, the Mova's extendable side brush system and mops with Roboswing optimise cleaning coverage. The Xiaomi offers extendable mops without that lateral movement, whilst the Roborock remains without mop extension.
Conclusion: Which to choose?
Choose the Mova P50 Ultra if you are looking for the best robot vacuum cleaner 2025 in overall performance, with maximum suction power, brush lifting systems, extendable mops with Roboswing, tray self-cleaning and the largest dust bag. It is the most complete option for those who want total automation and minimum maintenance, especially in homes with pets and carpets.
Choose the Roborock QV 35A if you value the confirmed autonomy of 180 minutes and trust a brand with an established reputation in the sector. It offers a solid balance between performance and reliability, with complete multifunction base and more compact base dimensions in width. A good option for large homes where autonomy is a priority.
Choose the Xiaomi X20 Max if you are looking for a more economical alternative without giving up essential functions such as extendable mops, 3D sensor and night LED. Although it has lower autonomy and lacks some of the Mova's advanced functions, it maintains a complete multifunction base and is suitable for medium-sized homes where maximum suction power is not required.
