Introduction
Dreame presents two generations of robot vacuum cleaners with multifunctional base stations that demonstrate the brand's technological evolution in barely two years. The Dreame L10s Ultra Gen 2, launched in 2024, represents a consolidated model with high-end features, whilst the Dreame X50s Ultra, scheduled for May 2026, incorporates significant improvements in almost all technical aspects.
We're looking at two devices designed for users seeking complete automation in home cleaning. Both feature a multifunctional base station that washes and dries the mops, automatic dust emptying and a mopping system with rotating mops. The main difference lies in the technological leap offered by the X50s Ultra, with improvements in power, intelligent navigation and advanced functions that position it in the highest market segment.
Power and Suction
The most striking difference between these Dreame robot vacuum cleaners lies in suction power. The L10s Ultra Gen 2 offers 10,000 Pa, a solid figure for most surfaces and types of dirt. The X50s Ultra multiplies this capacity up to 35,000 Pa, an exceptional power that sets it apart from the previous generation and proves especially useful on medium or long-pile carpets.
The brushing system also evolves notably. Whilst the 2024 model incorporates a single brush, the X50s Ultra features the double HyperStream brush, a specific Dreame design that significantly reduces hair tangles. For households with pets, this difference can define the daily user experience.
The X50s Ultra's side brush includes three improvements absent in its predecessor: it's extendable to better reach corners, liftable during mopping to avoid spreading wet dirt, and features anti-tangle technology. The L10s Ultra Gen 2 maintains a conventional side brush without these features.
Neither model incorporates a specific brush for skirting boards, although the mop extension system with Roboswing movement present in both helps to better clean edges.
Mopping
Both devices use a system of two rotating mops with edge extension and Roboswing movement, which allows the robot to make a slight turn to introduce the mop under furniture and overhangs. Mop lifting reaches 10.5 mm in both cases, sufficient to travel over thin carpets without wetting them.
The major difference comes with water temperature. The Dreame L10s Ultra Gen 2 mops with cold water, whilst the X50s Ultra incorporates hot water at 45°C for floor mopping. This detail improves the dissolution of stubborn stains and the cleaning of grease, especially in kitchens.
The 2026 model adds two functions absent in the previous one: automatic mop removal at the base station when only vacuuming is desired, avoiding having to do it manually, and dirt detection on both the mops and the floor. This latter function allows the robot to identify dirtier areas and reinforce cleaning autonomously, going over them until achieving an optimal result.
Regarding mop washing at the base station, the L10s Ultra Gen 2 performs it with cold water, whilst the X50s Ultra uses hot water, improving the removal of residue adhered to the mops. Both dry the mops with hot air, which helps prevent bad odours and bacterial proliferation.
Navigation System
The Dreame L10s Ultra Gen 2 features a conventional 3D LiDAR turret, a reliable laser navigation system that maps the home with precision. The X50s Ultra makes a significant leap with its retractable LiDAR, which conceals itself when not in use, contributing to reducing the robot's overall height.
Where they truly differ is in artificial intelligence. The 2024 model incorporates obstacle avoidance and pet recognition, but lacks a camera. The X50s Ultra integrates a dual RGB camera with LED illumination for night vision, enabling it to recognise up to 280 different types of obstacles, detect curtains to treat them carefully, and offer remote camera access from the mobile application.
Both feature a front 3D laser sensor and CleanGenius AI technology to optimise cleaning routes. However, only the X50s Ultra incorporates stain recognition through artificial intelligence, being able to identify specific dirt and adapt the cleaning mode.
Autonomy and Battery
Battery capacity increases from 5,200 mAh in the L10s Ultra Gen 2 to 6,400 mAh in the X50s Ultra. The 2024 model offers a declared autonomy of 240 minutes, sufficient for medium-large sized homes on a single charge. The X50s Ultra doesn't specify autonomy in minutes, although its greater battery capacity should translate into longer cleaning sessions, something important considering its higher suction power.
Smart Functions
The ability to overcome obstacles improves substantially. The Dreame L10s Ultra Gen 2 can overcome steps up to 20 mm, whilst the X50s Ultra overcomes single steps of 40 mm, doubling this capacity. In practice, this facilitates transit between rooms with small level differences or passage over sliding door tracks.
An exclusive feature of the X50s Ultra is its own built-in voice assistant integrated in the robot, which allows direct interaction without needing to use the mobile phone. Both models are compatible with external assistants such as Alexa or Google Home.
Multifunctional Cleaning Base Station
Both base stations perform automatic emptying of the dust container, washing and drying of mops with hot air, and include a detergent tank. The dust bag capacity is identical: 3.2 litres in both cases.
The X50s Ultra incorporates third-generation self-cleaning in the washing tray, a function that the L10s Ultra Gen 2 doesn't have. This reduces manual maintenance of the base station, preventing residue accumulation in the area where the mops are washed.
The water tanks present slight differences. The 2024 model has 4.5 litres of clean water and 4 litres of dirty water, whilst the X50s Ultra reduces the clean tank to 4.2 litres and the dirty one to 3 litres. In large homes, the first model may require fewer refills.
Both allow the purchase of an optional plumbing connection kit, although it doesn't come integrated as standard. Neither includes UV disinfection nor an automatic mop changing system.
Dimensions
The diameter is practically identical: 350 mm for the L10s Ultra Gen 2 and 352 mm for the X50s Ultra. The important difference is in height. The 2024 model measures 97 mm, whilst the X50s Ultra reduces to 79.5 mm thanks to its retractable LiDAR. This difference of almost 18 mm can prove decisive for passing under low furniture, beds or sofas.
The base stations also differ in size. The L10s Ultra Gen 2's measures 340 mm wide, 590.5 mm high and 456.7 mm deep. The X50s Ultra's is wider (390 mm) but less tall (499 mm) and somewhat less deep (423 mm). It's advisable to measure the available space before deciding, especially if planning to place it in a tight space.
Real-World User Experience
For medium-sized homes without special height requirements, the Dreame L10s Ultra Gen 2 offers a complete automated cleaning experience. Its 240-minute autonomy covers large surfaces, and the multifunctional base station minimises maintenance. It's a solid option for those seeking a reliable Dreame robot vacuum cleaner without needing the latest innovations.
The X50s Ultra is designed for demanding users who value maximum power and the most advanced functions. Its ability to pass under low furniture makes it ideal for homes with low-height furniture. Intelligent dirt detection and hot water mopping make a difference in kitchens or high-traffic areas.
In homes with pets, the X50s Ultra's double HyperStream brush significantly reduces maintenance of the main brush. The 35,000 Pa power also facilitates the vacuuming of hair embedded in carpets. Advanced obstacle recognition with dual camera improves navigation in spaces with toys or objects scattered on the floor.
The 2026 model's washing tray self-cleaning reduces the frequency with which manual intervention is needed at the base station, something worth considering if seeking maximum system autonomy.
