Introduction
We're looking at three high-end robots with complete multifunction bases, but with very different technical profiles. The Cecotec Conga X70 arrives in 2025 with a mid-range features proposition, whilst the Dreame L50s Pro Ultra lands in 2026 loaded with advanced technology and raw power. The Roborock Qrevo S5V, also from 2025, focuses on reliability and a compact design that could make the difference in homes with low furniture.
Each one meets different needs: from those seeking a complete robot without complications, to those who need maximum suction power or prioritise the unit fitting under sofas and beds without problems.
Power and Suction
The difference in suction power is enormous. The Dreame L50s Pro Ultra reaches 30,000 Pa, a figure that places it at the top of the market and doubles the 15,000 Pa of the Cecotec Conga X70. The Roborock Qrevo S5V stays at 12,000 Pa, which doesn't mean it vacuums poorly, but clearly focuses on other values over raw power.
Regarding brushes, the Cecotec mounts a traditional bristle brush, which tends to accumulate hair more easily. The Dreame equips its Doble Cepillo HyperStream system, designed specifically to minimise tangles. The Roborock incorporates its DuoDivide Antienredos, which pushes hair towards the central suction gap preventing it from wrapping around.
The side brush also marks important differences. The Dreame extends it to sweep corners better, raises it during mopping to avoid interference and features anti-tangle design. The Roborock has an anti-tangle side brush but without extension or raising. The Cecotec doesn't offer any of these advanced functions in its side brush.
Something only the Dreame does: raise the main brush when mopping. This prevents it from getting unnecessarily wet and improves mopping efficiency by not dragging wet dirt back to the brush.
Mopping
All three feature two rotating mops, but the Dreame raises them up to 10.5 mm, compared to the Roborock's 10 mm and the Cecotec's 8 mm. It may seem little, but those extra millimetres help to pass better over thick carpets without wetting them.
All extend the mops to mop edges better, although the Dreame adds the Roboswing system: a lateral movement that allows the mop to reach slightly under furniture or protrusions, improving coverage in difficult areas.
All three bases wash the mops with hot water and dry them with hot air, which guarantees good maintenance and prevents bad odours. However, only the Dreame can automatically remove the mops at the base when you only want to vacuum, without having to do it manually.
Dirt detection is exclusive to the Dreame. This model detects both dirt on the mops and on the floor, automatically adjusting the washing and scrubbing process as needed. Neither the Cecotec nor the Roborock have this function.
Navigation System
All three mount LiDAR turret and obstacle avoidance systems, but the difference lies in the sophistication of the artificial intelligence system.
The Dreame equips dual AI camera and recognises up to 220 different types of obstacles, including pets and curtains. Additionally, it allows remote camera access and has LED for night vision. This makes it the most complete for home surveillance or to see what your pet is doing when you're not there.
The Cecotec has a simple AI camera and front 3D laser sensor, but doesn't specify how many obstacles it recognises nor allows remote access. It also doesn't specifically detect pets or curtains.
The Roborock dispenses with AI camera and front 3D laser sensor, relying on its LiDAR and its SmartPlan system for intelligent cleaning. It's a more traditional approach but equally effective for most homes.
Autonomy and Battery
All three robots share the same battery capacity: 5,200 mAh. Only the Roborock specifies autonomy: 180 minutes of continuous operation, sufficient for large homes without needing intermediate recharges.
Neither the Cecotec nor the Dreame provide specific autonomy data, although with that battery capacity it's usual for them to exceed two hours of work. In practice, the Dreame's suction power could consume more battery at maximum power than the other two models.
Smart Functions
The ability to overcome obstacles varies considerably. The Cecotec reaches 30 mm, the Roborock stays at 20 mm and the Dreame overcomes simple steps, although it doesn't specify the exact height. For homes with thick carpets or small level differences between rooms, this can make the difference.
Only the Dreame incorporates its own voice assistant, in addition to compatibility with Alexa and Google Home. The Roborock is also compatible with these external assistants, but the Cecotec doesn't offer any voice integration.
Multifunction Cleaning Base
All three bases perform auto-emptying, washing with hot water and drying with hot air. But the Dreame adds third-generation tray self-cleaning, which keeps the base itself more hygienic without manual intervention.
The detergent tank is only included with the Dreame, which allows adding cleaning product that is automatically dosed during mop washing. Neither the Cecotec nor the Roborock offer this option.
In capacities, the Dreame also wins: 3.2-litre dust bag versus 2.7 for the Roborock and 2.5 for the Cecotec. In clean water it carries 4.5 litres versus 4 for the Cecotec and Roborock. In dirty water the Cecotec and Roborock tie with 3.5 litres, whilst the Dreame reaches 4 litres.
The Dreame offers an optional plumbing connection kit that is purchased separately, allowing the base to self-supply with clean water and dispose of dirty water without intervention. It's an extra that the other two don't contemplate.
Dimensions
The robot's height is critical for passing under furniture. The Roborock Qrevo S5V measures only 96.5 mm, which allows it to slip under most sofas and beds. The Dreame reaches 103.8 mm and the Cecotec reaches 110 mm, the highest figure of the three.
In diameter there's little difference: 340 mm for the Cecotec, 350 mm for the Dreame and 353 mm for the Roborock. All are similar sizes and manoeuvre well in tight spaces.
The bases have identical widths of 340 mm, but vary in height and depth. The Dreame's is the tallest at 590 mm, followed by the Roborock at 521 mm and the Cecotec at 450 mm. In depth, the Roborock needs 487 mm, the Dreame 457 mm and the Cecotec 425 mm. It's advisable to measure the space where the base will go carefully before deciding.
Real-World Experience
For homes with pets, the Dreame comes out on top for several reasons: its Doble Cepillo HyperStream minimises tangles, it has 30,000 Pa of power to suction hair embedded in carpets, it specifically recognises pets and allows you to monitor them by camera. The Roborock also handles hair well thanks to its DuoDivide, but without the power or AI functions of the Dreame. The Cecotec, with traditional bristle brush, requires more manual maintenance.
In large homes, the Roborock's declared autonomy (180 minutes) and the Dreame's more generous tanks (3.2 litres of dust, 4.5 of clean water) make the difference. The Cecotec, with the smallest bag and no autonomy data, may fall short in large surfaces.
If the home has low furniture, the Roborock wins hands down with its 96.5 mm height. It will access areas that the other two won't reach. The Cecotec, at 110 mm, is the one that will have the most limitations in this aspect.
For those seeking maximum automation and to forget about the robot, the Dreame offers automatic mop removal, dirt detection, tray self-cleaning, detergent tank and plumbing connection option. It's the most complete in this regard.
Conclusion: Which to Choose?
Choose the Cecotec Conga X70 if you're looking for a robot with complete multifunction base at a more competitive price and don't need the most advanced AI functions. It's suitable for medium-sized homes without pets and where furniture has sufficient height (more than 11 cm). Its ability to overcome 30 mm obstacles is useful with thick carpets.
Choose the Dreame L50s Pro Ultra if you want the maximum suction power on the market, have pets, need advanced obstacle recognition or value functions such as camera with remote access, automatic mop removal or detergent tank. Its 30,000 Pa and dirt detection make it the most complete and technological option, ideal for large homes and users seeking total automation.
Choose the Roborock Qrevo S5V if the robot's height is a priority because you have lots of low furniture. At only 96.5 mm it accesses where the others can't reach. Its DuoDivide system works well with pets, offers 180 minutes of confirmed autonomy and represents the most balanced option for those who trust an established brand without needing the most advanced AI functions. Perfect for homes with low furniture and users who prefer proven reliability over technological novelties.
