Introduction
The Cecotec Conga X70 and the Roborock Q7 L5+ or BF+ Plus are two proposals launched in 2025 that represent very different philosophies within the segment of robot vacuum cleaners with auto-empty base. Whilst the Cecotec model opts for more complete equipment with an advanced mopping system and multifunction base, the Roborock focuses on offering a robot vacuum cleaner with dust auto-empty in a more compact and straightforward proposal.
The main difference lies in the mopping system and the base's features. The Conga X70 includes mop washing and drying, something that the Roborock Q7 L5+ or BF+ Plus does not incorporate. This marks two clearly differentiated user profiles: those seeking an integral automated vacuuming and mopping solution, versus those who prioritise powerful vacuuming with automatic emptying without additional complications.
Power and Suction
The difference in suction power is considerable. The Cecotec Conga X70 reaches 15,000 Pa, almost double the 8,000 Pa of the Roborock Q7 L5+ or BF+ Plus. This figure translates into greater capacity to extract ingrained dirt, especially on carpets or in tile joints.
Regarding the brushing system, both units mount a bristle brush as the main element. Neither includes specific anti-tangle systems nor main brush lift during mopping. They also do not incorporate an extendable or liftable side brush, features that have begun to gain popularity in higher ranges.
The Conga X70's ability to overcome obstacles up to 30 mm represents a practical advantage over the Roborock's 20 mm. Those additional 10 millimetres can make the difference when tackling thick carpets or small level changes between rooms.
Mopping
Here we find the most significant difference between both models. The Cecotec Conga X70 integrates two rotating mops that extend to better reach edges, as well as lifting up to 8 mm when it detects carpets or areas where it should only vacuum. The Roborock Q7 L5+ or BF+ Plus mounts a static mop without extension or lift.
In practice, this means that the Conga X70 can alternate between vacuuming and mopping much more efficiently, protecting carpets and offering deeper mopping thanks to the rotary movement of the mops. The Roborock's system is more basic: it drags the mop across the floor without active movement or ability to lift it.
The water temperature for mopping the floor is cold in both cases. Neither of the two models includes dirt detection on mops or on the floor, nor automatic mop removal at the base to perform vacuum-only tasks.
Navigation System
Both robots use 3D LiDAR turret to map the home and plan efficient routes. However, the Cecotec Conga X70 adds AI camera and front 3D laser sensor for obstacle avoidance, something that the Roborock Q7 L5+ or BF+ Plus does not incorporate.
This difference is relevant in homes with objects scattered on the floor, cables or toys. The Conga X70's avoidance system allows it to identify and dodge these elements more precisely. The Roborock relies exclusively on its laser navigation and basic contact sensors.
Neither of the two models offers specific pet recognition, curtain detection, remote camera access or night vision LED. They also do not integrate AI-based intelligent cleaning functions or advanced stain recognition.
Autonomy and Battery
The Cecotec Conga X70's battery reaches 5,200 mAh, a figure notably higher than the 3,200 mAh of the Roborock Q7 L5+ or BF+ Plus. This difference should translate into greater autonomy, although specific operating time data is not available in the comparison.
With a higher capacity battery, the Conga X70 is better prepared for large homes or to complete mopping cycles that require greater energy consumption. The Roborock, with a more modest battery, may need intermediate recharges on extensive surfaces, although its auto-empty function allows it to resume cleaning after recharging without losing efficiency.
Smart Functions
The Roborock Q7 L5+ or BF+ Plus offers compatibility with external voice assistants such as Alexa or Google Home, allowing voice control of the robot's functions. The Cecotec Conga X70 does not include this integration.
For users accustomed to managing their home through voice commands, this Roborock feature can be very practical. It allows starting cleaning sessions, pausing the robot or sending it to the base without needing to open the mobile application.
Multifunction Cleaning Base
The Cecotec Conga X70's base is fully multifunction: it performs dust bin auto-empty, washes the mops with cold water and dries them with hot air. The clean and dirty water tanks have capacities of 4 and 3.5 litres respectively. The dust bag reaches 2.5 litres.
The Roborock Q7 L5+ or BF+ Plus only has dust auto-empty with a 2.7-litre bag. It does not wash or dry mops because its mopping system is passive and does not require automated maintenance. It also does not have water tanks in the base.
The Conga X70's hot air drying is especially useful for preventing bad odours and bacteria proliferation on the mops. Neither of the two bases includes tray self-cleaning, UV disinfection, detergent tank or plumbing connection options.
Dimensions
The Roborock Q7 L5+ or BF+ Plus is more compact: 325 mm in diameter and 99 mm in height, compared to the 340 mm diameter and 110 mm height of the Cecotec Conga X70. Those 11 millimetres difference in height can be decisive for slipping under low furniture, sofas or beds with little clearance.
The Roborock's base is also notably smaller: 212 mm wide, 259 mm high and 178 mm deep. The Conga X70's base measures 340 mm wide, 450 mm high and 425 mm deep. This difference reflects the complexity of each system: the Roborock only needs space for auto-empty, whilst the Conga X70 houses water tanks and washing and drying systems.
For homes with limited space or users who prefer a discreet base, the Roborock is more suitable. The Conga X70 requires more space, but in return offers complete autonomy in mopping.
Real-World Experience
The Cecotec Conga X70 is designed for those seeking to maximise automation of both vacuuming and mopping. Its 15,000 Pa power, high-capacity battery and rotating mop system with automatic washing and drying make it a complete option for medium or large homes where one wants to completely delegate floor maintenance.
The Roborock Q7 L5+ or BF+ Plus is aimed at users who prioritise vacuuming with auto-empty and value compactness. Its mopping is more basic, suitable for light maintenance but without the depth of the rotating mop system. Its lower height allows it to access tighter spaces.
In homes with pets, the Conga X70's greater power can make a difference, although neither incorporates specific anti-tangle brushes. The Roborock's compatibility with voice assistants facilitates control in homes already integrated into home automation ecosystems.
Conclusion: Which to Choose?
Choose the Cecotec Conga X70 if: you're looking for a robot vacuum cleaner with advanced mopping and multifunction base that washes and dries the mops automatically. It's ideal for large homes where complete autonomy is valued and sacrificing some space for the base doesn't matter. Its greater suction power and ability to overcome 30 mm obstacles make it versatile on different floor types.
Choose the Roborock Q7 L5+ or BF+ Plus if: you prefer a compact robot vacuum cleaner with dust auto-empty, without the need to manage water tanks or mop maintenance. Perfect for small spaces, low furniture or users who value integration with voice assistants. Its basic mopping fulfils light maintenance without additional complications.
