Introduction
The Dreame L50s Pro Ultra arrives in 2026 with a very ambitious technical proposition, going head-to-head with the Xiaomi Robot Vacuum 5 Pro from 2025 and the veteran Xiaomi X20 Max from 2024. All three models belong to the high-end range of robot vacuum cleaners with multifunction base, but the technical differences between them mark significant distances in terms of real performance.
Whilst the Dreame opts for maximum power and advanced features, the two Xiaomi models represent more established options on the market, with the Robot Vacuum 5 Pro positioned as a recent alternative and the X20 Max as a more economical reference within this robot vacuum cleaner comparison.
Power and Suction
The most obvious difference in this robot vacuum cleaner comparison is suction power. The Dreame L50s Pro Ultra reaches 30,000 Pa, a figure that far exceeds the Xiaomi Robot Vacuum 5 Pro's 20,000 Pa and almost quadruples the X20 Max's 8,000 Pa. In practice, this translates to greater capacity for picking up ingrained dirt from carpets and tile joints.
The brushing system also shows notable differences. The Dreame incorporates a dual HyperStream brush, specifically designed to reduce hair tangles thanks to its two brushes anchored at one end. The two Xiaomi models feature the TriCut 3.0 brush, which combines bristles with blades to cut tangled hair, albeit with a different technical approach.
In terms of versatility, the Dreame and the Xiaomi Robot Vacuum 5 Pro lift the main brush during mopping, a function the X20 Max doesn't offer. This allows more efficient mopping by avoiding dragging wet dirt with the brush. The side brush also presents differences: the Dreame is the only one that can lift it during mopping, as well as extending it to better reach corners. The Xiaomi Robot Vacuum 5 Pro extends its side brush, but doesn't lift it. The X20 Max lacks both functions.
All side brushes on the Dreame and the Robot Vacuum 5 Pro incorporate anti-tangle design, a feature absent on the X20 Max. For homes with pets or people with long hair, these differences can determine the frequency of maintenance required.
Mopping
All three robot vacuum cleaners use a dual rotating mop system, but the differences appear in the technical details. The Dreame L50s Pro Ultra integrates mop extension with Roboswing movement, which allows the robot to make a specific movement to get the mops under furniture and overhangs. The Xiaomi Robot Vacuum 5 Pro and the X20 Max also extend their mops, but without that additional movement.
Mop lift varies between models: the Xiaomi Robot Vacuum 5 Pro reaches 15 mm, the Dreame reaches 10.5 mm and the X20 Max stays at 10 mm. This difference is relevant when passing over carpets or mats during mopping mode, although in practice all three overcome typical household obstacles.
An exclusive function of the Dreame is automatic mop removal at the base. When you only need to vacuum without mopping, the robot leaves the mops at the station and goes out to work without them, avoiding dragging them unnecessarily across the floor. The Xiaomi models keep the mops installed at all times.
Dirt detection marks another clear difference. The Dreame L50s Pro Ultra and the Xiaomi Robot Vacuum 5 Pro detect dirt both on the mops and on the floor, adjusting mopping as needed. The X20 Max lacks this technology, which limits its ability to adapt cleaning to dirtier areas.
Navigation System
All models use LiDAR navigation and front 3D laser sensor to avoid obstacles, but the Dreame incorporates a dual AI camera whilst the Xiaomi Robot Vacuum 5 Pro features one camera and the X20 Max does without it. This difference directly impacts object recognition capability.
The Dreame robot vacuum cleaner recognises up to 220 different types of obstacles, including pets and curtains, two elements that the Xiaomi models don't specifically identify. The Xiaomi Robot Vacuum 5 Pro reaches 200 recognised objects, a considerable figure but without the Dreame's advanced categories. The X20 Max doesn't specify number of objects, and lacking an AI camera its recognition is more basic.
Remote camera access is available on the Dreame and on the Xiaomi Robot Vacuum 5 Pro, allowing you to see in real time what the robot is doing from the mobile app. The X20 Max doesn't offer this possibility. All three are equipped with LEDs for night vision, useful when working in poorly lit areas.
Autonomy and Battery
Battery capacity is identical across all three models: 5,200 mAh. However, real autonomy varies according to efficiency and power used. The Xiaomi Robot Vacuum 5 Pro declares 140 minutes of operation, whilst the X20 Max reaches 120 minutes. The Dreame L50s Pro Ultra doesn't specify concrete autonomy, probably because its greater suction power can generate significant variations depending on the cleaning mode used.
For medium or large-sized homes, any of the three models completes cleaning without problems thanks to their high-capacity batteries. In practice, autonomy rarely represents a limiting factor in robots of this range.
Smart Functions
The ability to overcome obstacles shows technical differences. The Dreame L50s Pro Ultra can tackle simple steps, whilst the Xiaomi Robot Vacuum 5 Pro and the X20 Max overcome obstacles up to 20 mm. This specific figure makes it easier to calculate whether the robot will be able to pass over thresholds or level changes at home.
The Dreame incorporates its own voice assistant, a function that allows direct interaction with the robot without going through external applications. The two Xiaomi models don't include their own assistant, although all three are compatible with Alexa and Google Home for voice control via external ecosystems.
Multifunction Cleaning Base
All three bases perform auto-emptying of the dust container, mop washing with hot water and drying with hot air, essential functions in a high-end multifunction base. The differences appear in capacities and additional functions.
The Dreame's dust bag reaches 3.2 litres, compared to 2.5 litres on the Xiaomi models. Greater capacity means fewer bag changes, especially relevant in homes with pets or high traffic. The clean water tank is also larger on the Dreame: 4.5 litres versus 4 litres on the Xiaomi models. Dirty water is stored in 4 litres on the Dreame and 3.8 litres on the other two.
The Dreame is the only one that includes a detergent tank in the base, dispensing product during mop washing to improve cleaning. It also incorporates third-generation tray self-cleaning, technology that improves maintenance of the base itself. The Xiaomi Robot Vacuum 5 Pro cleans its tray, but without specifying technological generation. The X20 Max doesn't include this function.
An additional detail: the Dreame offers an optional kit for plumbing connection, which must be purchased separately. Although it's not an integrated function, it may be interesting for those seeking to completely automate water filling and emptying. Neither of the Xiaomi models offers this possibility.
Dimensions
The diameter is identical across all three robots: 350 mm. The height, however, varies significantly. The Xiaomi Robot Vacuum 5 Pro measures 88 mm, the lowest in this robot vacuum cleaner comparison, which facilitates its passage under low furniture. The X20 Max reaches 97 mm and the Dreame L50s Pro Ultra reaches 103.8 mm, being the tallest of the group.
For homes with sofas, beds or furniture with little separation from the floor, the Xiaomi Robot Vacuum 5 Pro's height represents a clear advantage. The Dreame, with more than an additional centimetre, may have limitations in very tight spaces.
The bases also present dimensional differences. The Dreame measures 340 mm wide, 590 mm high and 457 mm deep. The Xiaomi Robot Vacuum 5 Pro is wider (360 mm) and deeper (470 mm), but less tall (572 mm). The X20 Max is the most compact base: 340 mm wide, 563 mm high and 420 mm deep. It's advisable to measure available space before deciding, especially if the base will go in areas with limited space.
Real-World Usage Experience
In large homes, the Dreame L50s Pro Ultra's greater bag and tank capacity reduces maintenance frequency. Its 30,000 Pa power is especially useful on thick carpets or floors with deep joints where dirt accumulates. Automatic mop removal adds convenience when you only need to vacuum specific rooms.
For homes with pets, the Dreame's dual HyperStream brush system and its specific animal recognition make a difference. The Xiaomi Robot Vacuum 5 Pro, with its anti-tangle TriCut 3.0 brush and reduced height, offers good performance although without specifically identifying pets. The X20 Max may require more manual maintenance on the main brush as it lacks advanced anti-tangle functions.
The Xiaomi Robot Vacuum 5 Pro stands out in homes with lots of low furniture thanks to its 88 mm height. Its 15 mm mop lift is also an advantage when moving over carpets during mopping. The absence of a detergent tank and lower bag capacity are acceptable limitations in medium-sized flats without pets.
The X20 Max is positioned as a functional option for those seeking a multifunction base without needing the latest technologies. Its lower suction power may be noticeable on carpets, and the absence of dirt detection limits automatic mopping adaptation. For hard floors in small or medium-sized homes it performs perfectly.
Conclusion: Which One to Choose?
