Introduction
The Cecotec Conga X70 and the Roborock S8 MaxV Ultra represent two different visions within the high-end range of robot vacuum cleaners. The Cecotec model arrives in 2025 with a suction power that reaches 15,000 Pa, whilst the Roborock S8 MaxV Ultra, launched in 2024, offers 10,000 Pa of power combined with a more developed artificial intelligence system. We're talking about two devices with complete multifunction bases, designed for users seeking to maximise home cleaning automation without sacrificing advanced features.
The difference in approach is clear: Cecotec opts for raw power and rotating mops, whilst Roborock integrates advanced recognition technology and intelligent functions that enhance the user experience. Both options are designed for medium to large-sized homes, although we'll see that the differences in navigation and mopping define distinct user profiles.
Power and Suction
The Cecotec Conga X70 stands out with a power of 15,000 Pa, a figure that exceeds the Roborock S8 MaxV Ultra by 5,000 Pa. This difference can be particularly noticeable on thick carpets or when there's an accumulation of persistent dirt. However, power isn't everything when we talk about cleaning efficiency.
The brushing system reveals different philosophies. The Conga X70 features a traditional bristle brush, effective but with a tendency to tangle hair. The S8 MaxV Ultra opts for the dual DuoDivide brush, specifically designed to push hair towards the central gap and minimise tangles. For homes with pets, this difference can be decisive in daily maintenance.
The side brush also marks a distance between both models. Only the Roborock includes an extendable side brush, which improves cleaning in corners and edges. Neither of them raises the side brush during mopping, but the Roborock model compensates for this with better perimeter navigation capability.
It's worth noting that the S8 MaxV Ultra's main brush is liftable during mopping, a function absent in the Conga X70. This allows the Roborock to mop without dragging dirt with the brush, keeping vacuuming and mopping tasks separate more efficiently.
Mopping
Here we find substantial differences that define the final result on the floor. The Cecotec Conga X70 uses two rotating mops with full edge extension, a system that offers good lateral coverage. The Roborock S8 MaxV Ultra features a vibrating mop with mini side mop, a more compact solution but equally effective on edges thanks to that additional element.
Mop lift shows very different figures: 8 mm in the Conga X70 and 20 mm in the S8 MaxV Ultra. When the robot passes over carpets, those additional 12 mm of the Roborock make the difference between grazing the surface or keeping the mops completely separated from the fabric. For homes with medium or long pile carpets, this feature is especially relevant.
Mop washing in the base also presents important variations. The Conga X70 washes with cold water, whilst the S8 MaxV Ultra uses hot water. The temperature helps to better eliminate grease residue and adhered dirt on the mops, improving the overall hygiene of the system. Both bases dry the mops with hot air, matching features in this section.
The Roborock incorporates dirt detection both on the mops and on the floor, automatically adjusting mopping when it detects dirtier areas. The Conga X70 doesn't include this function, performing standard mopping without intelligent adaptation. Additionally, only the S8 MaxV Ultra has a detergent tank in the base, dispensing product during mop washing to improve cleaning.
Navigation System
Both robots feature 3D LiDAR turret and front laser sensor for obstacle avoidance. The difference lies in the implementation of artificial intelligence. The Cecotec Conga X70 includes an AI camera, but the Roborock S8 MaxV Ultra goes further with dual camera and the ability to recognise up to 73 different types of obstacles.
The Roborock model identifies pets and allows remote camera access, functions absent in the Conga X70. This makes the S8 MaxV Ultra an interesting option for those who want to monitor their home whilst the robot cleans or have pets that require supervision. The Roborock's night vision LED completes a navigation system that's clearly superior in intelligent features.
The RR Mason 11.0 algorithm and SmartPlan 1.0 intelligent cleaning of the S8 MaxV Ultra allow adaptive planning according to the use of each room. AI-powered stain recognition activates automatic re-mopping in specific areas. The Conga X70 lacks these advanced functions, offering efficient navigation but without the additional layer of intelligence.
Autonomy and Battery
Both models are equipped with 5,200 mAh batteries, matching energy capacity. The Roborock declares 180 minutes of autonomy, a figure that the Conga X70 doesn't specify. In practice, with identical batteries, consumption will depend on the power used and the functions active during cleaning.
The Conga X70's higher suction power may translate into greater consumption when working at maximum performance, although this is speculative without specific autonomy data. For large homes, it's worth considering that both robots will automatically return to the base to recharge and continue cleaning if necessary.
Intelligent Functions
The Cecotec Conga X70 overcomes obstacles up to 30 mm in height, compared to the 20 mm of the Roborock S8 MaxV Ultra. Those additional 10 mm can be useful in homes with pronounced transitions between rooms or small steps. For spaces with floors at the same level, the difference lacks practical relevance.
The S8 MaxV Ultra integrates its own voice assistant and compatibility with external assistants such as Alexa or Google Home. The Conga X70 doesn't include any of these options, limiting voice control. For users accustomed to home automation ecosystems, this absence may be limiting.
Multifunction Cleaning Base
Both bases offer auto-emptying of the dust bin, washing and drying of mops with hot air. The capacities are identical: 2.5-litre dust bag, 4-litre clean water tank and 3.5-litre dirty water tank. Neither integrates tray self-cleaning, UV disinfection nor connection to plumbing.
The key difference is in the detergent tank, present only in the Roborock S8 MaxV Ultra. This allows the base to automatically dispense product during mop washing, improving hygiene without manual intervention. The Conga X70 requires adding product manually if you wish to use detergent.
The S8 MaxV Ultra's hot water washing also adds points in maintenance and hygiene, better eliminating greasy residue than the Conga X70's cold water. For those seeking to minimise maintenance tasks, these differences tip the balance towards the Roborock model.
Dimensions
The Cecotec Conga X70 measures 340 mm in diameter and 110 mm in height. The Roborock S8 MaxV Ultra reaches 353 mm in diameter but only 103 mm in height. Those 7 mm less of the Roborock facilitate access under low furniture, sofas or beds with little clearance from the floor. The Conga X70's smaller diameter can help in tight spaces, although 13 mm of difference is rarely decisive.
The Conga X70's base measures 340 mm wide, 450 mm high and 425 mm deep. The S8 MaxV Ultra's reaches 409 mm wide, 470 mm high and 419 mm deep. The Cecotec model is more compact in width and depth, occupying less floor space. The 20 mm difference in height barely influences the final location of the base.
Real-world experience
For homes with pets, the Roborock S8 MaxV Ultra's dual DuoDivide brush significantly reduces maintenance related to tangled hair. The Conga X70's bristle brush requires more frequent cleaning in this scenario. The S8 MaxV Ultra's pet detection adds an extra level of control for those who want to supervise their animals during cleaning.
In homes with a combination of hard floors and carpets, the Roborock's 20 mm lift better protects the mops and prevents dampening fabrics. The Conga X70, with only 8 mm of lift, may graze medium pile carpets during mopping. If the home has mainly hard floors, this difference loses importance.
The Conga X70's 15,000 Pa power is advantageous on thick carpets or when there's significant dirt accumulation. For daily cleaning on hard floors, the Roborock's 10,000 Pa is more than sufficient, especially considering its more efficient brushing system against hair.
The S8 MaxV Ultra's remote camera access and AI functions enhance the experience for tech-savvy users who value supervision and advanced control. The Conga X70 offers a more straightforward experience, without the additional layer of intelligence but with effective results in basic cleaning.
