Introduction
The Cecotec Conga X70 and the Xiaomi X20 Max represent two different propositions within the robot vacuum cleaner segment with multifunction base. The Cecotec model arrives in 2025 focusing on superior suction power, whilst the Xiaomi X20 Max, launched in 2024, centres on a more complete navigation system with advanced artificial intelligence functions.
These devices are designed for users looking to fully automate home cleaning. Both include a multifunction base that handles self-emptying, mop washing and drying, which significantly reduces manual maintenance. The choice between one or the other will depend on priorities: raw power versus navigation intelligence.
Power and Suction
The most notable difference between these robots lies in suction power. The Cecotec Conga X70 practically doubles the capacity of the Xiaomi X20 Max with its 15,000 Pascals compared to 8,000. This advantage translates into better performance on carpets and in picking up ingrained dirt.
Regarding the brushing system, we find different philosophies. The Conga X70 mounts a traditional bristle brush, whilst the Xiaomi X20 Max equips the TriCut 3.0 system, which combines bristles with blades designed to cut hair and reduce tangles. For homes with pets, this feature of the Xiaomi model is especially practical.
Neither model incorporates an extendable or liftable side brush during mopping. Nor do they have anti-tangle systems on the side brush. Battery capacity is identical in both cases: 5,200 mAh.
Mopping
Both robots use the same system of two rotating mops with edge extension, which allows more complete mopping reaching right up to the skirting boards. Mop lifting presents a slight difference: the Conga X70 lifts them 8 mm, whilst the Xiaomi X20 Max reaches 10 mm. Those additional 2 mm can make a difference when passing over short-pile carpets.
The major distinction appears in the washing of mops inside the base. The Xiaomi X20 Max washes with hot water, which improves the removal of grease and adhered dirt on the mops. The Cecotec Conga X70 carries out this process with cold water, less effective for difficult stains. Both dry the mops with hot air, which helps prevent bad odours and bacterial growth.
Neither model automatically removes the mops at the base to perform vacuum-only passes. Nor do they include dirt detection on mops or on the floor for automatic re-mopping of dirtier areas.
Navigation System
Here the Xiaomi X20 Max takes a clear advantage. Although both equip 3D LiDAR turret and front 3D laser sensor to avoid obstacles, the Xiaomi model adds functions that the Conga X70 does not have. It integrates intelligent cleaning via AI that optimises routes and cleaning patterns according to room type and detected dirt level.
The Cecotec Conga X70 does incorporate an AI camera, but without the advanced functions of the Xiaomi. The latter adds night vision LED, useful for navigating in low-light conditions without bumping into objects. Neither offers specific pet recognition, curtain detection nor remote camera access for video surveillance.
In practice, the Xiaomi X20 Max should offer more refined and adaptive navigation, whilst the Conga X70 focuses on precise mapping but less intelligent in terms of autonomous decision-making.
Autonomy and Battery
With 5,200 mAh capacity, both robots share the same battery. The Xiaomi X20 Max declares 120 minutes of autonomy, a figure that the Cecotec Conga X70 does not specify. This autonomy is sufficient for medium-large sized homes, allowing cleaning to be completed in a single pass in most cases.
It is usual that with the maximum suction power of the Conga X70 (15,000 Pa), autonomy is considerably reduced compared to use in standard modes. Energy consumption increases proportionally to the power employed.
Intelligent Functions
The Cecotec Conga X70 stands out for its ability to overcome obstacles up to 30 mm in height, 10 mm more than the Xiaomi X20 Max, which remains at 20 mm. This difference can be determining in homes with thick carpets, small level differences between rooms or sliding door guides.
The Xiaomi X20 Max incorporates compatibility with external voice assistants such as Alexa or Google Home, facilitating voice control. The Conga X70 does not offer this integration. Neither device has its own voice assistant nor articulated robotic arm.
Multifunction Cleaning Base
The bases of both models share many characteristics: self-emptying of the dust container, washing and drying of mops with hot air, and similar capacities in the containers. The dust bag has 2.5 litres in both cases, and the clean water tank reaches 4 litres.
The dirty water tank presents a small difference: 3.5 litres in the Conga X70 compared to 3.8 litres in the Xiaomi X20 Max. The 300 ml difference has barely any practical relevance. The major distinction, as already mentioned, is in the water temperature for washing mops: hot in the Xiaomi, cold in the Cecotec.
Neither includes self-cleaning of the washing tray, UV disinfection, detergent tank nor connection to water pipes. Nor do they offer an optional kit for this connection.
Dimensions
The Xiaomi X20 Max is lower with its 97 mm height, which allows it to slip under furniture where the Conga X70, at 110 mm, would not reach. Those 13 mm difference can be decisive under sofas, beds or low furniture. The diameter is practically equal: 340 mm for the Conga compared to 350 mm for the Xiaomi.
The bases present similar dimensions in width (340 mm both) and depth (425 mm for the Conga, 420 mm for the Xiaomi). The base height varies more: 450 mm for the Cecotec compared to 563 mm for the Xiaomi, a difference of more than 11 centimetres that should be considered depending on available space.
Real-World User Experience
For homes with pets, the Xiaomi X20 Max offers advantages with its TriCut 3.0 brush that reduces hair tangles, although the greater power of the Conga X70 also helps to better suction hair embedded in carpets. The hot water mop washing of the Xiaomi represents a plus in effective cleaning, especially in kitchens where grease accumulates.
In homes with many obstacles or thick carpets, the Conga X70's ability to overcome 30 mm makes a difference. If the house has low furniture, the more reduced profile of the Xiaomi X20 Max (97 mm) is determining for accessing areas that the Conga would not reach.
The intelligent navigation of the Xiaomi provides convenience to the user who prefers to delegate completely to the robot without complex configurations. Voice control via Alexa or Google Home adds an extra point of convenience. The Conga X70 compensates with raw power, ideal for those who prioritise vacuuming results over advanced automation.
Conclusion: Which to Choose?
Choose the Cecotec Conga X70 if... you need maximum suction power for thick carpets or very dirty floors, you have obstacles over 20 mm at home (carpets, door guides), and you don't mind doing without advanced AI functions. Also if you're looking for a robot that can slip under intermediate-height furniture and prefer a more compact base in height.
Choose the Xiaomi X20 Max if... you value intelligent navigation with AI, want mops to be washed with hot water for better hygiene, need a robot that passes under very low furniture (less than 10 cm), have pets and prefer an anti-tangle brush, or wish to control the robot via Alexa or Google Home. Its more automated and intelligent cleaning system compensates for the lower suction power in most homes without long-pile carpets.
