Introduction
The Mova P50 Pro Ultra and the Xiaomi X20 Max represent two recent offerings in the robot vacuum segment with multifunction base stations. The former arrives in 2025 as a high-end model seeking to stand out in power and advanced features, whilst the latter landed in 2024 as a solid alternative with balanced characteristics.
Both units are designed for homes seeking complete cleaning automation, with simultaneous vacuuming and mopping capability. However, the technical differences between them are notable and may influence the user experience depending on the type of home and the specific needs of each user.
Power and Suction
The most evident difference in this robot vacuum comparison appears in suction power. The Mova P50 Pro Ultra develops 19000 Pa in Turbo mode, a figure that more than doubles the 8000 Pa of the Xiaomi X20 Max. In practice, this translates to greater capacity to extract embedded dirt from carpets and to pick up heavier particles or food debris.
Both models mount the same TriCut 3.0 main brush with anti-tangle technology already installed. This system combines bristles with blades that cut long hairs, reducing the tangles common in homes with pets or people with long hair.
Where we do find important differences is in lifting capabilities. The Mova robot vacuum can lift both the main and side brushes during mopping, preventing them from getting wet and dragging dirt over damp surfaces. The Xiaomi X20 Max does not have these functions, which may affect efficiency when alternating between vacuuming and mopping.
The side brush on the P50 Pro Ultra also incorporates extension to better reach corners and anti-tangle technology. The Xiaomi model maintains a conventional side brush without these improvements. For homes with many corners or hard-to-reach areas, this feature makes a difference.
Mopping
Both units use a dual rotating mop system, but the Mova P50 Pro Ultra adds Roboswing 3.0 technology, which allows the robot to perform lateral movements to introduce the mop under furniture or overhangs. The Xiaomi X20 Max includes mop extension for edges, although without specifying version or additional characteristics.
Mop lift reaches 10.5 mm on the Mova model and 10 mm on the Xiaomi, practically equivalent figures that allow transit over medium-thickness carpets without wetting them.
Mop washing presents significant differences. The P50 Pro Ultra washes with water at 75°C, a temperature that helps disinfect and remove adhered grease. The X20 Max also washes with hot water, although it does not specify exact temperature. Drying follows the same line: 45°C with hot air on the Mova, hot air without specified temperature on the Xiaomi.
An exclusive function of the Mova robot vacuum is the ability to leave the mops at the base automatically when only vacuuming is needed. This avoids having to remove them manually. It also incorporates dirt detection on both the mops themselves and the floor, adjusting washing and scrubbing according to need. The Xiaomi X20 Max lacks both functions, which implies greater manual intervention.
Navigation System
Both robots mount LiDAR 3.0 turret for laser mapping and front 3D sensor for obstacle avoidance. They also have LED for night vision. However, the Mova P50 Pro Ultra incorporates dual camera with artificial intelligence, whilst the Xiaomi X20 Max does not have any camera.
This difference proves decisive in object recognition. The Mova model identifies up to 160 different types of obstacles, including pets and curtains, adapting its behaviour according to what is detected. The X20 Max does not specify how many objects it recognises and lacks specific detection of pets or curtains.
The remote camera access on the P50 Pro Ultra allows home monitoring from the mobile application, a function that is not available on the Xiaomi X20 Max as it lacks a camera. For homes with pets or monitoring needs, this may prove an important added value.
Both units boast intelligent cleaning via AI, although the Mova adds specific stain recognition to intensify cleaning in specific areas.
Autonomy and Battery
Although both models integrate 5200 mAh batteries, the declared autonomy differs notably. The Mova P50 Pro Ultra reaches 210 minutes of continuous operation, whilst the Xiaomi X20 Max remains at 120 minutes. This hour-and-a-half difference may be explained by optimisations in energy management or by differences in measurement modes.
In homes of more than 150 square metres, the greater autonomy of the Mova model reduces interruptions for recharging and allows complete cleaning sessions to be completed in one go. The X20 Max may need intermediate recharges on large surfaces or when high-power modes are activated.
Smart Features
The ability to overcome obstacles reaches 22 mm on the Mova P50 Pro Ultra compared to 20 mm on the Xiaomi X20 Max. Those additional 2 millimetres may seem irrelevant, but in practice they facilitate passage over thresholds, thick carpets or cables without getting stuck.
The Mova robot vacuum incorporates its own voice assistant described as "simple", which suggests basic voice control functions. The Xiaomi model does not include an integrated voice assistant, although it is probably compatible with external assistants such as Google or Alexa through the application.
Multifunction Cleaning Base
The base of the Mova P50 Pro Ultra stands out for its third-generation tray self-cleaning system, already installed from the factory. This means that the base itself cleans automatically after washing the mops, preventing accumulation of dirt and bad odours. The Xiaomi X20 Max does not have tray self-cleaning, requiring periodic manual cleaning.
The integrated detergent reservoir on the P50 Pro Ultra allows cleaning product to be added which is automatically dispensed during mop washing. The X20 Max lacks this reservoir, limiting itself to using only water.
The dust bag capacity reaches 3.2 litres on the Mova model and 2.5 litres on the Xiaomi. This translates to fewer manual emptyings, especially relevant in homes with pets or high dust generation.
The clean water tanks are identical (4 litres), but the Mova specifies 3.5 litres for dirty water, a detail that Xiaomi does not provide. As for the robot's own tanks, the P50 Pro Ultra includes 300 ml for dust and 80 ml for water, whilst the X20 Max only specifies that it has a water tank without stating capacities.
Neither offers connection to water pipes, either integrated or via optional kit.
Dimensions
The diameter is identical on both: 350 mm. Height marks the main difference. The Xiaomi X20 Max measures 97 mm, whilst the Mova P50 Pro Ultra reaches 103.8 mm. Those almost 7 additional millimetres may determine whether or not the robot accesses under certain low furniture, sofas or beds with little clearance from the floor.
The bases present different configurations. The Mova's is wider (420 mm vs 340 mm) and deeper (458 mm vs 420 mm), but less tall (470 mm compared to 563 mm). The Xiaomi X20 Max base grows vertically, which may facilitate its placement in narrow spaces but requires more overhead clearance.
Real-World User Experience
The Mova P50 Pro Ultra positions itself as the most complete option for large homes seeking minimal manual intervention. Its 210-minute autonomy and 19000 Pa power make it especially suitable for large surfaces with carpets or much accumulated dirt. The dirt detection on mops and floor, together with the tray self-cleaning system, drastically reduce maintenance.
For homes with pets, the specific animal recognition and greater suction power of the Mova model represent clear advantages. The anti-tangle side brush and the ability to leave the mops at the base automatically simplify daily use.
The Xiaomi X20 Max proves more suitable for medium-sized homes where height under furniture is limited. Its 97 mm height allows it to access spaces where the P50 Pro Ultra would be blocked. The 120-minute autonomy covers flats of up to 100-120 square metres without problems.
The absence of camera and advanced AI functions on the X20 Max positions it as a more straightforward alternative, without additional technological complications. Base maintenance requires more attention as it lacks tray self-cleaning and detergent reservoir.
Conclusion: Which to Choose?
Choose the Mova P50 Pro Ultra if you are looking for the best robot vacuum 2025 in complete features, you live in a large house with carpets, you have pets and you prefer minimal manual intervention. The 19000 Pa power, extended autonomy, dual AI camera, advanced dirt detection and base with self-cleaning justify its premium positioning. Also if you value being able to monitor the home via remote camera access.
Choose the Xiaomi X20 Max if your priority is being able to clean under low furniture thanks to its reduced height of 97 mm, you live in a medium-sized flat and you prefer an effective solution without the need for advanced artificial intelligence features. Its relationship between basic features and price proves more balanced for users who do not require maximum power or autonomy.
In short, this comparison between the Mova robot vacuum and the Xiaomi robot vacuum shows two philosophies: maximum automation and features on the P50 Pro Ultra versus direct efficiency and access under furniture on the X20 Max. The choice will depend on the size of your home, the height of your furniture and the level of automation you seek in your daily cleaning.
