Introduction
Xiaomi has launched two new robot vacuum models in 2025 that compete directly with its 2024 predecessor. The Xiaomi Robot Vacuum 5 and the Xiaomi Robot Vacuum 5 Pro represent the brand's latest generation, whilst the Xiaomi X20 Max remains available as an alternative from the previous year. All three units feature a multifunction base that washes and dries the mops, which guarantees effective mopping instead of the mediocre results offered by robots without this technology.
The main difference between these models lies in suction power and artificial intelligence capabilities. The two 2025 releases multiply the power of the X20 Max by 2.5, reaching 20,000 Pa compared to the previous model's 8,000 Pa. This translates into much deeper cleaning, especially on carpets and in homes with pets.
The Xiaomi Robot Vacuum 5 Pro stands out as the most advanced model of the three, incorporating an artificial intelligence camera that recognises up to 200 different obstacles. This feature marks a clear difference from its siblings, which are limited to 3D laser sensors for navigation.
Power and Suction
The power difference between generations is spectacular. With 20,000 Pa, the Xiaomi Robot Vacuum 5 and the Robot Vacuum 5 Pro offer significantly superior suction capacity to the X20 Max. In practice, this means that the 2025 models can extract much more embedded dirt from carpets and vacuum pet hair more effectively.
All three units feature the TriCut 3.0 brush, which combines bristles with blades to cut tangled hair. However, the Robot Vacuum 5 Pro adds the ability to lift this main brush during mopping, preventing it from getting wet and improving the efficiency of the wet cleaning process.
The side brush also presents notable differences. Both 2025 models incorporate an extendable and anti-tangle side brush, features we don't find on the X20 Max. The extendable brush allows better sweeping of corners, whilst the anti-tangle design reduces necessary maintenance. These details make a difference in homes with pets or people with long hair.
Mopping
All three robots use two rotating mops with an extension system to better reach edges. Mop lift varies by model: 15 mm on the Robot Vacuum 5 and the Robot Vacuum 5 Pro, compared to 10 mm on the X20 Max. Those additional 5 mm facilitate passage over medium-pile carpets without wetting them.
The Robot Vacuum 5 Pro incorporates dirt detection on both the mops and the floor. This allows the robot to identify dirtier areas and scrub them automatically, as well as detecting when the mops need additional washing at the base. This intelligent function is not available on the other two models.
All three multifunction bases wash the mops with hot water and dry them with hot air. This process ensures that the mops are always clean during mopping and eliminates bad odours that appear when mops remain damp. The 2025 models add self-cleaning of the washing tray, reducing the manual maintenance that the X20 Max does require.
None of the three units automatically removes the mops at the base when we only want to vacuum, so it will be necessary to remove them manually if we're planning a vacuum-only session.
Navigation System
The navigation system represents one of the most significant differences between these robots. The Xiaomi Robot Vacuum 5 Pro features an artificial intelligence camera capable of recognising up to 200 different obstacles, a capability that neither the Robot Vacuum 5 nor the X20 Max possess. This camera allows the robot to identify objects more precisely and adapt its cleaning behaviour.
All three models feature a front 3D laser sensor to detect obstacles, but the Robot Vacuum 5 Pro and the X20 Max add a night vision LED that improves detection in low-light conditions. The Robot Vacuum 5 lacks this front LED.
Remote camera access is exclusive to the Robot Vacuum 5 Pro. This function allows you to see in real time what the robot is doing or even monitor the home when we're away, turning the unit into a mobile security camera.
The 2025 models use retractable LiDAR, whilst the X20 Max features a traditional LiDAR turret. The retractable system contributes to reducing the robot's height to 88 mm, facilitating access under low furniture.
Autonomy and Battery
All three robots feature the same 5,200 mAh battery, but autonomy varies slightly. The Xiaomi Robot Vacuum 5 and the Robot Vacuum 5 Pro achieve 140 minutes of continuous operation, whilst the X20 Max remains at 120 minutes. This 20-minute difference can be relevant in large homes or when we want to complete all the cleaning in a single session.
The higher suction power of the 2025 models doesn't penalise autonomy, which suggests better energy management. In practice, 140 minutes allow cleaning of large surfaces without the need for intermediate recharges.
Smart Functions
All three units can overcome thresholds up to 20 mm in height, a useful capability for moving between rooms with small level changes or climbing onto thick carpets without getting stuck.
All models are compatible with external voice assistants such as Alexa or Google Home, allowing control via voice commands. Integration with these systems facilitates home automation and scheduling of cleaning routines.
Multifunction Cleaning Base
All three bases share fundamental features: auto-emptying of the dust container, mop washing with hot water and drying with hot air. The tanks are also identical: 2.5 litres for the dust bag, 4 litres for clean water and 3.8 litres for dirty water. These capacities are generous and allow several days of cleaning without maintenance.
Self-cleaning of the washing tray appears on the Robot Vacuum 5 and the Robot Vacuum 5 Pro, but not on the X20 Max. This function automatically cleans the area where the mops are washed, preventing accumulation of dirt and bad odours. On the X20 Max it will be necessary to clean this tray manually on a regular basis.
None of the bases include a detergent tank, UV disinfection or connection to water pipes. There is also no optional kit to connect the bases to pipes, so it will be necessary to refill and empty the tanks manually.
Dimensions
The diameter of all three robots is identical: 350 mm. Height marks the main difference. The Xiaomi Robot Vacuum 5 and the Robot Vacuum 5 Pro measure 88 mm in height, whilst the X20 Max reaches 97 mm. Those additional 9 mm may prevent the X20 Max from accessing under some furniture where the more recent models would fit.
The bases of the 2025 models are slightly larger: 360 mm wide, 572 mm high and 470 mm deep. The X20 Max has a somewhat more compact base at 340 mm wide, 563 mm high and 420 mm deep. It's advisable to measure the available space before deciding, although the differences aren't dramatic.
Real-World Experience
For large homes, the 2025 models offer clear advantages: greater autonomy, more power and better cleaning management. The ability to vacuum for 140 minutes allows completion of large surfaces without interruptions. The X20 Max may require recharges in very large houses.
If you live with pets, the anti-tangle side brush of the new models notably reduces maintenance. The 20,000 Pa power also makes a difference when extracting embedded hair from carpets. The X20 Max may fall short in this scenario.
The reduced height of 88 mm on the 2025 units allows access under more furniture. If you have sofas or beds with little clearance, this feature is decisive. The X20 Max, at 97 mm, will encounter more limitations.
The Robot Vacuum 5 Pro stands out in homes where we value advanced artificial intelligence. Dirt detection optimises mopping automatically, and remote camera access adds surveillance functionality. For those seeking the maximum level of automation, this model justifies its investment.
Conclusion: Which to Choose?
Choose the Xiaomi Robot Vacuum 5 if you're looking for the latest in power and performance without needing advanced AI functions. This model offers 20,000 Pa of suction, extendable and anti-tangle side brush, 140 minutes of autonomy and reduced height of 88 mm. It's ideal for medium and large homes with pets, where power and low maintenance are priorities. The base with self-cleaning tray reduces manual tasks.
Choose the Xiaomi Robot Vacuum 5 Pro if you want the most advanced robot in this comparison. The AI camera with 200-obstacle recognition, intelligent dirt detection on mops and floor, remote camera access and liftable main brush during mopping justify the price difference. Perfect for those who value maximum automation and want a robot that makes intelligent decisions without intervention. Also for those who want to use the camera as an additional surveillance system.
Choose the Xiaomi X20 Max if your budget is tighter and you don't need maximum power. With 8,000 Pa it remains capable of cleaning most homes correctly, although it will fall short with thick carpets or abundant pet hair. The more compact base may be advantageous in reduced spaces. Bear in mind that it doesn't include self-cleaning of the washing tray, which increases manual maintenance. It's a valid option for small flats without pets and with a limited budget, but the advances of the 2025 models justify the investment difference in most cases.
