Introduction
This comparison pits three models representing different approaches within the robot vacuum segment with multifunction base stations. The Mova E30 Ultra arrives in 2024 as an offering from a brand belonging to the Dreame ecosystem, whilst Xiaomi presents two options: the Robot Vacuum 5 from 2025, its most recent proposition, and the X20 Max from 2024, which has already been on the market for a year.
All three units share the philosophy of offering complete cleaning with minimal user intervention, thanks to bases that wash and dry the mops automatically. However, differences in suction power, brushing systems and lifting capabilities mark out quite distinct usage profiles.
Power and Suction
Suction power marks considerable distances in this robot vacuum comparison. The Xiaomi Robot Vacuum 5 dominates with its 20000 Pa, a figure that positions it as the best robot vacuum 2025 in terms of brute force. This capability proves decisive for dense carpets or floors with ingrained dirt.
The Xiaomi X20 Max remains at 8000 Pa, whilst the robot vacuum Mova offers 7000 Pa in Turbo mode. Although these figures may seem modest compared to the 2025 model, in practice they remain sufficient for most homes with hard floors and short-pile carpets.
Regarding brushing, both Xiaomi models mount the TriCut 3.0 system already factory-installed, which combines bristles with blades to cut hair and reduce tangles. The Mova E30 Ultra comes with a simple brush, although an anti-tangle system can be fitted as an additional accessory. This difference is worth considering if you live with long-haired pets.
The Xiaomi Robot Vacuum 5's side brush includes two significant advantages: extension to better reach corners and anti-tangle technology. Neither the Mova nor the X20 Max feature these characteristics in their side brush, which can translate into less effective corner cleaning and greater manual maintenance.
Mopping
All three robots employ dual rotating mop systems, but differences appear in the details. Mop lifting varies: the Xiaomi Robot Vacuum 5 reaches 15 mm, the Mova E30 Ultra achieves 10.5 mm and the X20 Max remains at 10 mm. Those extra millimetres on the 2025 model can make the difference when traversing thick carpets or small obstacles.
Mop extension for edge mopping is present on both Xiaomi models, but not on the robot vacuum Mova. This means the E30 Ultra leaves a larger strip uncleaned next to skirting boards and corners during mopping.
The Xiaomi Robot Vacuum 5's mop washing with hot water at 80°C represents a qualitative leap compared to the cold water used by both the Mova E30 Ultra and the X20 Max. Hot water dissolves grease better and eliminates more bacteria, keeping the mops in better hygienic condition. All three models dry the mops with hot air, which helps prevent bad odours.
None of the three allows automatic mop removal at the base to perform vacuum-only sessions without accidental wetting. Nor do they incorporate dirt detection systems in mops or floor that adjust mopping intensity.
Navigation System
The Xiaomi Robot Vacuum 5 mounts a retractable Lidar system, whilst the Mova E30 Ultra and the X20 Max employ traditional Lidar turrets. The 2025 model's retractable design contributes to its lower height of 88 mm, facilitating access under low furniture.
All three units integrate a front 3D laser sensor for obstacle avoidance, but only the robot vacuum Mova includes specific pet recognition. This function can prove useful if you have cats or dogs at home, as the robot adjusts its behaviour to avoid startling them.
The Xiaomi X20 Max incorporates night vision LED, absent in the other two models. This feature improves navigation in low-light conditions, although its real day-to-day impact is limited given that Lidar systems function independently of ambient lighting.
All feature AI-powered intelligent cleaning, although none offers remote camera access nor specific stain or curtain recognition.
Autonomy and Battery
Battery capacity is identical across all three models: 5200 mAh. However, autonomy data is only available for the Xiaomi robots. The Robot Vacuum 5 offers 140 minutes of continuous operation, whilst the X20 Max reaches 120 minutes.
That 20-minute difference can be explained by software optimisations or by the higher consumption involved in moving 20000 Pa of power in the most recent model. In any case, both figures prove sufficient for medium-sized homes, and all three robots automatically resume cleaning after recharging if they haven't finished.
Smart Functions
All three models share the ability to overcome obstacles up to 20 mm in height, sufficient to transit between rooms with small level changes or pass over thick cables. This function proves especially useful in homes with different floor types or transitions between rooms.
None incorporates a robotic arm nor its own voice assistant, functions that are beginning to appear in higher-end models but haven't yet reached these units.
Multifunction Cleaning Base
The Xiaomi Robot Vacuum 5's base includes self-cleaning of the washing tray, a feature that significantly reduces manual maintenance. Neither the Mova E30 Ultra nor the X20 Max offer this function, which means manually cleaning the tray with some regularity to avoid dirt accumulation and bad odours.
The robot vacuum Mova stands out with a 3.2-litre dust bag, compared to the 2.5 litres of both Xiaomi models. This greater capacity translates into less frequent emptying, especially relevant for large homes or those with pets that generate lots of hair.
Water tanks also favour the Mova E30 Ultra: 4.5 litres of clean water and 4 litres of dirty water, compared to the Robot Vacuum 5's 4 and 3.8 litres respectively. The X20 Max has 4 litres of clean water, but the dirty water tank capacity isn't specified.
None of the three offers a detergent tank, UV disinfection nor connection to water pipes, functions that are beginning to appear in higher-priced models.
Dimensions
The diameter is identical across all three: 350 mm. Height marks the main difference. The Xiaomi Robot Vacuum 5 measures 88 mm, allowing it to slip under furniture where the other two will have problems. Both the Mova E30 Ultra and the X20 Max reach 97 mm in height, almost a centimetre more that can limit access under sofas or low beds.
The bases also present variations. The Mova's measures 340 mm wide, 590.5 mm high and 456.7 mm deep. The Robot Vacuum 5 has a base of 360 x 572 x 470 mm, whilst the X20 Max is the most compact in height at 340 x 563 x 420 mm.
These differences can prove decisive if available space for the base is limited. The X20 Max offers the least deep base, which facilitates its placement in corridors or tight corners.
Real-World Usage Experience
For large homes, the Mova E30 Ultra presents clear advantages thanks to its greater bag capacity and more generous water tanks. This reduces maintenance frequency, although its lower suction power may be noticeable on demanding carpets.
If you live with pets, the Xiaomi Robot Vacuum 5 proves the most complete option. Its factory-installed TriCut 3.0 system, anti-tangle side brush and 20000 Pa power handle abundant hair better. The Mova's pet recognition is an interesting detail, but the Xiaomi model's brushes offer more tangible day-to-day advantages.
For those seeking maximum convenience with minimum maintenance, the Robot Vacuum 5's mop washing at 80°C and tray self-cleaning make a difference. These functions keep the mopping system more hygienic without frequent manual intervention.
Access under furniture clearly favours Xiaomi's 2025 model. Those 9 mm less in height compared to the Mova and X20 Max can mean cleaning or not cleaning under a good portion of your home's furniture.
Conclusion: Which to Choose?
Choose the Mova E30 Ultra if you have a large home and prefer to empty the dust bag and refill the water tanks less frequently. Its 3.2-litre capacity and superior water tanks reduce maintenance, although you'll have to settle for lower suction power and no mop extension for edges. Pet recognition can be a plus if you have animals at home.
Choose the Xiaomi Robot Vacuum 5 if you're looking for the best robot vacuum 2025 in terms of overall performance. Its 20000 Pa power, mop washing at 80°C, extendable and anti-tangle side brush, tray self-cleaning and reduced height of 88 mm make it the most advanced option. Ideal for homes with pets, demanding carpets and users who value minimal manual intervention.
Choose the Xiaomi X20 Max if you want a balance between features and more compact base dimensions. Its night vision LED can prove useful, and although it doesn't reach the 2025 model's power, its 8000 Pa remains sufficient for most homes. The less deep base facilitates its placement in reduced spaces, although you'll miss the tray self-cleaning and hot water washing.
