Introduction
The Cecotec Conga X70 and the Dreame X50 Ultra Blanca represent two high-end proposals launched in 2025, each with features that mark important differences in day-to-day use. Whilst the Cecotec model opts for a compact design with essential mopping functions, the Dreame X50 Ultra Blanca integrates advanced artificial intelligence technology and a more complete cleaning system. This robot vacuum comparison analyses the technical specifications to identify which model best suits each type of home and cleaning needs.
Both robots include a multifunction base with auto-emptying and mop washing, but the differences in power, navigation and smart functions are notable.
Power and Suction
The difference in suction power is significant. The Dreame X50 Ultra Blanca reaches 20,000 Pa, exceeding the Cecotec Conga X70 by 5,000 Pa. This greater suction capacity is especially useful on carpets or when there are pets at home, where more hair and ingrained dirt accumulates.
The brushing system marks another important difference. The Conga X70 uses a traditional bristle brush, whilst the Dreame is equipped with the Doble Cepillo HyperStream, specifically designed to prevent hair tangles. For homes with pets, this detail can mean the difference between cleaning the brush every two days or practically forgetting about maintenance.
The Dreame's main brush lifts during mopping, preventing it from getting unnecessarily wet. The Conga X70 does not include this function. As for the side brush, the Dreame incorporates extension to better reach corners, lifting during mopping and anti-tangle design. The Cecotec robot vacuum lacks these three features, which can affect effectiveness on edges and corners.
Mopping
Both models feature dual rotating mop systems with edge extension. The Dreame X50 Ultra adds the Roboswing system, which performs a specific movement to introduce the mop under furniture and overhangs, something the Conga X70 does not offer.
Mop lifting reaches 8 mm in the Cecotec and 10.5 mm in the Dreame. Those additional 2.5 mm can make the difference when passing over medium-pile carpets or preventing wet mops from touching unwanted surfaces.
Where they really differ is in mop washing. The Conga X70 washes with cold water and dries with hot air. The Dreame X50 Ultra Blanca washes with hot water and also dries with hot air. Hot water removes grease and adhered dirt better, improving mopping hygiene. Additionally, the Dreame incorporates dirt detection both on the mops and on the floor, automatically adjusting cleaning intensity. The Cecotec does not have this function.
Another relevant aspect: the Dreame can automatically remove the mops at the base to perform vacuuming only without dragging the mops through areas where mopping is not desired. The Conga X70 does not have this capability.
Navigation System
Both robot vacuums integrate LiDAR navigation and camera with artificial intelligence. The Cecotec Conga X70 features a 3D LiDAR turret with an AI camera, whilst the Dreame X50 Ultra Blanca is equipped with retractable LiDAR and dual AI camera. This dual configuration allows the Dreame to recognise up to 200 different types of obstacles.
The Dreame robot vacuum includes specific recognition of pets and curtains, functions absent in the Conga X70. It also incorporates night vision LED and remote camera access, allowing you to monitor the home from your mobile. The Cecotec does not offer any of these features.
The Dreame's processor uses the AI Sage 13.0 Octa-Core algorithm with the CleanGenius function, which learns from cleaning habits and optimises routes. The Conga X70 does not specify this level of detail in its processing system.
Autonomy and Battery
The Dreame X50 Ultra Blanca's battery has 6,400 mAh and offers 180 minutes of autonomy. The Cecotec Conga X70 is equipped with a 5,200 mAh battery, but does not specify operating minutes. In practice, this 1,200 mAh difference can translate into approximately 30-40 additional minutes of continuous work for the Dreame, sufficient to cover larger homes without the need for intermediate recharging.
Smart Functions
The Cecotec Conga X70 can overcome steps of up to 30 mm. The Dreame X50 Ultra Blanca climbs single steps of 4 cm, surpassing the Conga in obstacle-crossing capability. This is useful in houses with different floor levels or complicated transitions between rooms.
The Dreame integrates its own voice assistant in addition to compatibility with Alexa and Google Home. The Cecotec does not include any of these voice control functions, which limits handling options without using the mobile app.
Multifunction Cleaning Base
Both bases perform auto-emptying, mop washing and drying. However, the Dreame X50 Ultra Blanca incorporates third-generation tray self-cleaning, UV disinfection and detergent tank. The Conga X70 does not have any of these three features.
The dust bag capacity is 2.5 litres in the Cecotec and 3.2 litres in the Dreame. The clean water tanks measure 4 litres and 4.5 litres respectively, whilst dirty water is stored in 3.5 litres versus 4 litres. Moderate differences that may mean less frequent emptying or filling in the Dreame model.
The Dreame offers an optional plumbing connection kit that is purchased separately, allowing complete automation of water filling and emptying. The Conga X70 does not have this option.
Dimensions
The diameter is similar: 340 mm in the Conga X70 and 350 mm in the Dreame X50 Ultra. The big difference is in height. The Cecotec measures 110 mm, whilst the Dreame only reaches 89 mm. Those 21 mm of difference allow the Dreame robot vacuum to access under furniture, beds and sofas where the Conga X70 cannot enter.
The bases have an identical width of 340 mm. The height varies considerably: 450 mm in the Cecotec versus 590.5 mm in the Dreame. The depth is 425 mm and 456.7 mm respectively. The Dreame's base occupies more vertical space due to the additional functions it integrates.
Real-World Usage Experience
For homes with pets, the Dreame X50 Ultra Blanca offers clear advantages: greater suction power, HyperStream anti-tangle brush, specific pet recognition and anti-tangle side brush. The Conga X70, with its traditional bristle brush, requires more manual maintenance in these environments.
In large houses, the Dreame's larger battery and its 180-minute autonomy guarantee completing cleaning without intermediate recharges. The larger dust tank also reduces maintenance frequency.
The Dreame's reduced height is decisive in homes where cleaning under low furniture is desired. At 89 mm, it accesses spaces forbidden to the Conga X70 and its 110 mm height.
The Dreame's hot water mop washing notably improves mopping hygiene, especially in kitchens or areas with grease. Dirt detection and automatic re-mopping add a level of cleanliness that the Conga X70 does not achieve.
For those seeking total automation, the Dreame allows automatic mop removal, remote camera access, voice assistant and optional plumbing connection kit. The Cecotec offers a more basic experience that requires greater manual intervention.
Conclusion: Which to Choose?
Choose the Cecotec Conga X70 if you're looking for a robot vacuum with mopping functions and multifunction base at a more competitive price, in a small or medium-sized home without pets, where the robot's height is not a limiting factor and you don't need advanced artificial intelligence functions. It's a functional option for keeping the house clean without technical complications.
Choose the Dreame X50 Ultra Blanca if you want the best robot vacuum in terms of power, technology and automation. Ideal for large houses, homes with pets, users who value passing under low furniture, seek maximum mopping hygiene with hot water and UV disinfection, want voice control and remote camera access, or plan to connect the system to plumbing to completely forget about water maintenance. The differences between both models justify choosing the Dreame for those who prioritise advanced features and superior cleaning results.
