Introduction
The Dreame X50 Ultra Blanca and the Dreame X50s Ultra represent two consecutive generations within the brand's most advanced range. The former arrived on the market in 2025, whilst the latter was launched in May 2026. We are looking at robot vacuum cleaners with a multifunction base that combine powerful suction, mopping with rotating mops and navigation systems with artificial intelligence. Both models are designed for users seeking maximum autonomy in home cleaning, with particular attention to automated mopping and intelligent obstacle recognition.
The time difference between both launches translates into significant technical improvements that are worth analysing to understand what each model offers.
Power and Suction
The most evident evolution between these models is found in suction power. The X50 Ultra Blanca offers 20,000 Pa, already a notable figure for most domestic surfaces. However, the X50s Ultra raises this capacity to 35,000 Pa, which represents a 75% increase. In practice, this difference is particularly noticeable on long-pile carpets and in picking up fine particles embedded in irregular textures.
Both units feature Dreame's HyperStream dual brush system, designed to minimise hair tangles. This type of brush is especially useful in homes with pets, as hair becomes less trapped than with conventional bristle brushes. Both models include main brush lifting during mopping, which prevents contaminating the mops with dry dirt.
The side brush presents the same characteristics in both: it is extendable to better reach corners, lifts during mopping and features anti-tangle technology. This combination proves effective for sweeping edges without dragging tangled hair throughout the house.
Mopping
Both robots use a system of two rotating mops with extension capability and Roboswing movement, which allows the robot to make a slight wiggle to get the mops under overhangs and low furniture. Mop lifting reaches 10.5 mm in both cases, sufficient to transit over thin carpets without wetting them.
The major difference appears in floor mopping. The X50 Ultra Blanca works with cold water, whilst the X50s Ultra incorporates hot water at 45°C that is distributed directly onto the floor. This improves the dissolution of grease and stuck-on stains, especially in kitchens or high-traffic areas. For those seeking deeper mopping results, this function makes a difference.
Regarding the base, both wash the mops with hot water and dry them with hot air, which ensures the mops return clean and odour-free after each session. Both models automatically detach the mops at the base when only vacuuming is desired, and feature dirt detection both on the mops and on the floor, which activates additional scrubbing when necessary.
Navigation System
Navigation is based on retractable LiDAR in both models, which allows precise mapping and efficient route planning. Both incorporate a dual camera with artificial intelligence for object recognition, although the X50s Ultra specifies that it uses RGB cameras with improved lighting for obstacle avoidance, which suggests better detection in low-light conditions.
The leap in recognition capacity is notable: the X50 Ultra Blanca identifies up to 200 different objects, whilst the X50s Ultra extends this register to 280. This translates into fewer manual interventions and greater capacity to dodge toys, cables, slippers or pet excrement.
Both robots recognise pets, detect curtains to avoid tangling and feature LEDs for night vision. They also allow remote access to the camera from the app, which facilitates home surveillance or pet location. Both use Dreame's CleanGenius system to automatically adjust power and cleaning type according to the detected surface.
Autonomy and Battery
Both models feature a 6,400 mAh battery. The X50 Ultra Blanca declares an autonomy of 180 minutes, although this data is not specified for the X50s Ultra. Considering that the latter's suction power is higher, its maximum autonomy is likely to be somewhat lower when working at maximum power, although in standard mode the difference should not be significant.
In any case, both robots are designed for medium-to-large sized homes, and their automatic recharging capability with cleaning resumption allows them to cover large surfaces without user intervention.
Smart Features
Both the X50 Ultra Blanca and the X50s Ultra can overcome simple steps of up to 4 cm, which facilitates passage between rooms with small level differences or access to thick carpets. Neither incorporates a robotic arm.
Both models include their own voice assistant and compatibility with external assistants such as Alexa or Google Home, which allows them to be controlled through voice commands integrated into the home ecosystem.
Multifunction Cleaning Base
The bases of both robots perform auto-emptying of the dust container into a 3.2-litre bag, wash the mops with hot water and dry them with hot air. Both feature third-generation self-cleaning in the washing tray and have a detergent tank.
An important difference is UV disinfection, present in the X50 Ultra Blanca but absent in the X50s Ultra. This function adds an extra hygienisation step at the base, although its absence in the more recent model does not compromise the effective cleaning of the mops.
The water tanks present slight variations: the X50 Ultra Blanca has 4.5 litres of clean water and 4 litres of dirty water, whilst the X50s Ultra slightly reduces these capacities to 4.2 and 3 litres respectively. In practice, these differences barely affect daily use, except in very large homes where mopping is done in a single session.
Both models offer an optional plumbing connection kit that is purchased separately, allowing automation of water filling and emptying if one wishes to dispense with manual maintenance of the tanks.
Dimensions
The X50s Ultra has managed to reduce the robot's height to 79.5 mm, compared to 89 mm for the X50 Ultra Blanca. This difference of almost a centimetre can prove decisive for passing under low furniture, sofas or beds with little clearance from the floor. The diameter is practically identical: 350 mm compared to 352 mm.
The bases also present changes. The X50 Ultra Blanca's measures 340 mm wide, 590.5 mm high and 456.7 mm deep. The X50s Ultra's is lower (499 mm) and less deep (423 mm), but wider (390 mm). This may influence base placement depending on available space.
Real-World User Experience
The X50 Ultra Blanca is suitable for medium-sized homes with complete cleaning needs. Its 20,000 Pa power is sufficient for hard floors, parquet and short or medium-pile carpets. The HyperStream dual brush system and anti-tangle side brush work well in homes with pets, minimising manual maintenance.
The X50s Ultra, with its 35,000 Pa and hot water for floor mopping, is designed for those seeking maximum performance in mopping and vacuuming. The greater power is noticeable on thick carpets and in removing stuck-on dirt. Its lower height facilitates access under furniture, something that can make a difference in living rooms with low sofas or bedrooms with contemporary design beds.
The X50s Ultra's expanded recognition capacity (280 objects compared to 200) reduces the chances of blockage in homes with young children or pets that leave toys scattered about. In both cases, the multifunction base minimises maintenance: you only need to refill water and empty tanks every several weeks, depending on home size and frequency of use.
Conclusion: Which to Choose?
Choose the Dreame X50 Ultra Blanca if you're looking for a complete robot with a multifunction base and UV disinfection, and don't need maximum suction power or hot water for floor mopping. It's a solid option for medium-sized homes with hard floors and moderate-thickness carpets, especially if you value the additional hygienisation provided by the UV system in the base.
Choose the Dreame X50s Ultra if you prioritise maximum suction power (35,000 Pa), mopping with hot water at 45°C and the ability to pass under lower furniture thanks to its 79.5 mm height. Its expanded object recognition makes it especially recommendable for homes with pets, children or high obstacle density. The absence of UV in the base is compensated by washing and drying with hot water and air, which already guarantee clean, odour-free mops.
