Introduction
Dreame presents two high-end proposals launched in 2026 that compete directly with each other: the L50s Pro Ultra and the X50s Ultra. Both units belong to the manufacturer's most advanced category, with a complete multifunction base that includes washing and drying of mops with hot water, as well as auto-emptying of the dust bin. The fundamental difference lies in the design approach: whilst the L50s Pro Ultra maintains a more traditional configuration with a visible laser turret, the X50s Ultra opts for a retractable LiDAR system that significantly reduces the robot's height.
These models are designed for users seeking total autonomy in cleaning and who don't want to worry about daily maintenance. The object recognition capability, automatic mop washing and hot air drying make them ideal options for medium or large-sized homes, especially those with pets or requiring frequent mopping.
Power and Suction
The 5,000 Pa difference between both models may seem significant on paper. The X50s Ultra delivers 35,000 Pa of suction power, which represents a 16% increase compared to the L50s Pro Ultra's 30,000 Pa. In practice, this translates into greater capacity to extract ingrained dirt from carpets or tile joints.
Both units feature the same HyperStream dual brush system, specifically designed to prevent hair tangles. This type of brush is especially useful in homes with pets, as long hairs tend to slide towards the central gap without wrapping around the bristles. Additionally, both can raise the main brush during mopping to avoid wetting carpets.
The side brush also shares characteristics in both models: extendable to better reach corners, raisable during mopping and with an anti-tangle design. This configuration allows effective perimeter cleaning without dragging hairs or threads towards the robot's side.
Mopping
Here appears one of the most relevant differences for those who prioritise mopping. The X50s Ultra incorporates hot water at 45°C for mopping the floor, whilst the L50s Pro Ultra works with cold water. Hot water dissolves grease stains better and improves results in kitchens or high-traffic areas.
Both robots use two rotating mops that can extend to reach edges, complemented with the Roboswing system that allows the robot to make a slight lateral movement to get the mop under furniture or protrusions. Mop lifting reaches 10.5 mm in both cases, sufficient to pass over medium-thickness carpets without wetting them.
Mop washing is carried out with hot water in both bases, which guarantees deep cleaning after each session. Drying also employs hot air in both models, accelerating the process and reducing the proliferation of bacteria or bad odours. The third generation of self-cleaning of the washing tray keeps the base itself in hygienic conditions without manual intervention.
Both units detect the level of dirt on both the mops and the floor, automatically adjusting the washing frequency or mopping intensity. Additionally, they can remove the mops at the base when only vacuuming is needed, avoiding dragging them unnecessarily around the home.
Navigation System
The main technical distinction between these models lies in the LiDAR system. The L50s Pro Ultra maintains a traditional 3D laser turret, whilst the X50s Ultra incorporates a retractable LiDAR that hides inside the robot's body when not mapping. This difference explains the notable height reduction of the X50s Ultra.
The X50s Ultra can recognise up to 280 different obstacles thanks to its artificial intelligence system, surpassing the L50s Pro Ultra's 220. Both feature dual AI camera and front 3D laser sensor to avoid small objects such as cables, toys or pet excrement. Specific recognition of pets and curtains is present in both, as is the night vision LED for working in low light.
The remote camera access function allows monitoring the house from your mobile, turning the robot into an additional security device. The CleanGenius AI system manages cleaning intelligently in both models, recognising stains and adjusting cleaning patterns according to floor type or detected dirt level.
Autonomy and Battery
The X50s Ultra is equipped with a 6,400 mAh battery, clearly superior to the L50s Pro Ultra's 5,200 mAh. This 1,200 mAh difference represents approximately 23% more capacity, which should translate into longer cleaning sessions before returning to the base to recharge.
For large homes or floors with many rooms, this greater autonomy can make the difference between completing cleaning in a single run or needing several intermediate recharges. The combination of larger battery and greater suction power in the X50s Ultra suggests that Dreame has optimised the energy efficiency of the more recent model.
Smart Functions
Both robots can overcome simple steps, facilitating passage between rooms with small level differences or entry to showers with raised trays. This capability is useful in homes with floors at different heights or transitions between rooms.
Both models integrate their own voice assistant, as well as compatibility with Alexa and Google Home. This allows controlling the robot through voice commands without needing to take out your mobile, a convenience appreciated when your hands are occupied.
Multifunction Cleaning Base
Both bases share most functions: auto-emptying of the dust bin into a 3.2-litre bag, mop washing with hot water, hot air drying and third-generation self-cleaning of the washing tray. Both include a detergent tank, which improves mopping results.
The difference lies in the water tank capacity. The L50s Pro Ultra offers 4.5 litres of clean water and 4 litres of dirty water, whilst the X50s Ultra reduces these figures to 4.2 and 3 litres respectively. For large homes, these additional 300-1000 ml can mean an extra mopping session without manually refilling the tanks.
Both models allow purchasing an optional kit to connect the base directly to water pipes, completely eliminating the need to refill or empty tanks. This option is especially suitable for those seeking maximum autonomy or who have difficulty manipulating the tanks frequently.
Dimensions
The X50s Ultra measures 79.5 mm in height, which allows it to slip under low furniture, beds or sofas where the L50s Pro Ultra cannot access with its 103.8 mm. This difference of more than 24 mm is decisive in homes with Scandinavian furniture with low legs or beds with reduced-height storage bases.
The diameter is practically identical: 350 mm in the L50s Pro Ultra compared to 352 mm in the X50s Ultra. Neither presents a significant advantage for manoeuvring in tight spaces or corridors.
The bases have different configurations. The L50s Pro Ultra's is narrower (340 mm compared to 390 mm) but also taller (590 mm compared to 499 mm) and deeper (457 mm compared to 423 mm). It's advisable to measure the available space before deciding, especially if you plan to place the base in a cupboard or under furniture.
Real-World Usage Experience
The X50s Ultra adapts better to homes with low furniture thanks to its reduced height. If you have trundle beds, modern sofas with short legs or low shelving units, this model can clean areas inaccessible to the L50s Pro Ultra. The greater suction power also benefits homes with thick carpets or pets that shed a lot of hair.
The X50s Ultra's hot water for mopping makes a difference in kitchens with grease splashes or areas where sticky dirt accumulates. For those who mop daily or have young children, this function notably improves the final result.
The L50s Pro Ultra compensates with larger water tanks, which reduces maintenance frequency in spacious homes. If your house exceeds 120-150 square metres and you mop the entire surface at once, these extra litres can save you interruptions.
Both models manage pet hair well thanks to the HyperStream dual brush and anti-tangle side brush. Excrement detection and specific animal recognition add security for those living with dogs or cats.
Conclusion: Which to Choose?
Choose the Dreame L50s Pro Ultra if: you have a large home where you value water tank capacity more than the robot's height. If your furniture allows a 10.4 cm robot to pass without problems and you prefer to minimise manual base maintenance, the 4.5 litres of clean water and 4 litres of dirty water will allow you to mop more surface area without intervention. It's also suitable if you're looking for a balance between advanced features and a proven design with traditional laser turret.
Choose the Dreame X50s Ultra if: height is a critical factor in your home. At only 7.95 cm it can access under low beds, modern sofas or Scandinavian furniture where other robots cannot reach. The greater suction power (35,000 Pa) benefits those with thick carpets or pets that shed a lot of hair. Hot water for mopping the floor improves results in kitchens or areas with difficult stains. The 6,400 mAh battery and recognition of up to 280 obstacles make it the most technologically advanced option, ideal for those seeking Dreame's latest innovations and who don't want compromises in features.
