Introduction
The Dreame X50s Ultra and the Xiaomi Robot Vacuum 5 Pro represent two high-end propositions within the robot vacuum market with multifunction base. The Dreame model arrived in May 2026, whilst the Xiaomi unit was launched in 2025. Both are designed for users seeking a complete cleaning solution with minimal manual intervention, with capability for both vacuuming and advanced mopping.
The main difference between these models lies in raw power and the technologies applied to mopping and navigation. The Dreame X50s Ultra opts for superior suction power and more refined functions, whilst the Xiaomi Robot Vacuum 5 Pro offers more generous mop lifting and a declared autonomy of 140 minutes. Both are intended for medium or large homes with frequent mopping requirements.
Power and Suction
The difference in suction power is notable. The Dreame X50s Ultra reaches 35,000 Pa, a figure that far exceeds the 20,000 Pa of the Xiaomi Robot Vacuum 5 Pro. In practice, this translates to greater capacity for extracting embedded dust from carpets and tile joints.
The brushing system also differs. The Dreame features a Doble Cepillo HyperStream, specifically designed to prevent hair tangles thanks to its dual roller configuration anchored at one end. The Xiaomi uses the TriCut 3.0 system, which combines bristles with blades to cut tangled hair. Both approaches work well with pets, although the HyperStream tends to require less maintenance.
Both models feature a liftable main brush during mopping and an extendable side brush to better reach corners. However, only the Dreame X50s Ultra incorporates a liftable side brush, which prevents this element from dragging wet dirt during mopping. Both side brushes are anti-tangle.
Mopping
Both robot vacuums use two rotating mops for mopping, with extension to reach edges. The Dreame X50s Ultra adds the Roboswing system, which allows the robot to perform a swaying movement to slightly insert the mop under furniture or overhangs.
Mop lifting is more generous on the Xiaomi Robot Vacuum 5 Pro: 15 mm versus the 10.5 mm of the Dreame. This can be useful in homes with medium-pile carpets, although in most cases 10.5 mm is sufficient to avoid wetting carpets.
The Dreame mops with hot water at 45 °C, whilst the Xiaomi uses cold water. Hot water dissolves grease and stuck-on stains better, which makes a difference in kitchens or high-traffic areas. Additionally, the Dreame X50s Ultra can automatically remove the mops at the base when only vacuuming is desired, a function the Xiaomi does not offer.
Both units detect dirt on both the mops and the floor, activating rewashing or rescrubbing cycles when necessary. This intelligence applied to mopping significantly improves final results.
Navigation System
Both models feature retractable LIDAR and front 3D laser sensor, which guarantees precise navigation and real-time obstacle detection. The difference lies in the AI camera: the Dreame X50s Ultra incorporates a dual camera, whilst the Xiaomi has a single one.
The Dreame recognises up to 280 different obstacles, surpassing the 200 of the Xiaomi. Additionally, it includes specific recognition of pets and curtains, something the Xiaomi Robot Vacuum 5 Pro does not offer. This can be relevant in homes with animals, where the robot can identify and avoid toys, feeding bowls or resting areas.
Both allow remote access to the camera and feature front LED for night vision. Both integrate intelligent AI-based cleaning and stain recognition, automatically adjusting power and cleaning pattern according to detected dirt.
Autonomy and Battery
The Dreame X50s Ultra features a 6,400 mAh battery, superior to the 5,200 mAh of the Xiaomi. However, the Xiaomi declares an autonomy of 140 minutes, whilst the Dreame does not specify this data in the table. The Dreame's greater battery capacity suggests extended autonomy, especially considering it can modulate power according to surface.
For large homes, the Dreame's battery capacity offers an additional margin that can reduce the need for intermediate recharges during complete cleaning sessions.
Smart Functions
The Dreame X50s Ultra can overcome simple steps, whilst the Xiaomi Robot Vacuum 5 Pro reaches 20 mm in height. This capability is useful in homes with transitions between rooms or small level differences between floors.
The Dreame incorporates its own voice assistant, in addition to compatibility with Alexa and Google Home. The Xiaomi only offers compatibility with external assistants. This built-in function allows more direct interactions without depending on other devices.
Multifunction Cleaning Base
Both bases are complete multifunction: they auto-empty the dust container, wash the mops with hot water and dry them with hot air. The Dreame X50s Ultra uses a third-generation tray self-cleaning system, which implies greater efficiency in eliminating residue accumulated in the base itself.
The Dreame includes an integrated detergent tank, dispensing product during mop washing. The Xiaomi does not have this function, which requires adding detergent manually if desired. The dust bag capacity is 3.2 litres in the Dreame versus 2.5 litres in the Xiaomi, reducing replacement frequency.
The clean water tanks are similar: 4.2 litres in the Dreame and 4 litres in the Xiaomi. Dirty water is stored in 3 litres in the Dreame and 3.8 litres in the Xiaomi. The Dreame offers an optional plumbing connection kit, purchased separately, for those wishing to completely automate water filling and emptying.
Dimensions
The Dreame X50s Ultra measures 79.5 mm in height, versus the 88 mm of the Xiaomi Robot Vacuum 5 Pro. This difference of almost one centimetre can be decisive for passing under low furniture, sofas or beds with little clearance from the floor. The diameter is practically identical: 352 mm in the Dreame and 350 mm in the Xiaomi.
The Dreame's base has dimensions of 390 mm width, 499 mm height and 423 mm depth. The Xiaomi's measures 360 mm width, 572 mm height and 470 mm depth. The Xiaomi's base is taller and deeper, whilst the Dreame's is wider but more compact in height. It's advisable to measure available space before deciding.
Real-World Experience
The Dreame X50s Ultra is intended for users seeking maximum automation and power. Its hot water mopping capability, automatic mop removal and detergent tank make it an ideal option for large homes with hard floors requiring frequent mopping. The dual camera and pet recognition add a bonus in homes with animals.
The Xiaomi Robot Vacuum 5 Pro offers a more balanced solution, with superior mop lifting and a declared autonomy of 140 minutes. Its lower height allows access to more spaces under furniture, something that can make a difference depending on layout. The absence of a detergent tank and automatic mop removal implies somewhat more manual intervention.
Both models handle pet hair well thanks to their anti-tangle brushing systems. The Dreame's superior power is more effective on thick carpets or in homes with heavy dust accumulation. The Xiaomi, with its 15 mm mop lifting, can traverse medium-pile carpets without problems.
Conclusion: Which to Choose?
Choose the Dreame X50s Ultra if: you seek maximum suction power and hot water mopping, you have pets and value advanced obstacle recognition, you prefer a base with integrated detergent tank and third-generation self-cleaning, you need to automatically remove mops when only vacuuming, or you have tall furniture and prioritise extended battery capacity.
Choose the Xiaomi Robot Vacuum 5 Pro if: you have low furniture and need a shorter robot to access more spaces, you value 15 mm mop lifting for medium-pile carpets, you seek an option with declared autonomy of 140 minutes, you prefer a more compact base in width although somewhat taller, or you don't need functions like detergent tank or automatic mop removal and prefer an adjusted price-to-quality ratio.
In large homes with pets and intensive mopping requirements, the Dreame X50s Ultra makes a difference. For spaces with low furniture and users who prioritise accessibility under furniture, the Xiaomi Robot Vacuum 5 Pro is more practical.
