Introduction
In this robot vacuum comparison, we analyse two Roborock models that represent different approaches within the brand's high-end range: the Roborock Qrevo CurvX, launched in 2025, and the Roborock Qrevo Slim, introduced in 2024. Both Roborock robot vacuums share the brand's design philosophy and quality, but differ significantly in power, navigation capabilities and advanced features.
The Roborock Qrevo CurvX positions itself as the most advanced model, with superior technical specifications and cutting-edge technologies. For its part, the Roborock Qrevo Slim, true to its name, stands out for its compact design and a balance between performance and accessibility. If you're looking for which is better for your home, this comparison between the Qrevo CurvX and the Qrevo Slim will help you make the right decision.
Power and Suction
One of the most notable differences between the Roborock Qrevo CurvX and the Qrevo Slim is found in suction power. The Qrevo CurvX reaches 22000 Pa, practically doubling the 11000 Pa of the Qrevo Slim. This difference translates into superior capability for vacuuming ingrained dirt, pet hair and fine particles on high-pile carpets.
Regarding the brushing system, both models adopt different philosophies. The Roborock Qrevo CurvX incorporates the innovative DuoDivide Antienredos de Pelos main brush, specifically designed to prevent long hair and fur from tangling in the roller, facilitating maintenance. The Qrevo Slim, on the other hand, features a dual silicone brush system, an equally effective solution that reduces tangles and is especially useful in homes with pets.
Mopping
Although specific data about the mopping system is not completely detailed in the technical specifications of these models, both Roborock robot vacuums incorporate mopping functions as part of their comprehensive cleaning proposition. The water tank capacity is slightly different: 69 ml in the Qrevo CurvX versus 72 ml in the Qrevo Slim, a minimal difference that will not significantly affect mopping autonomy in most homes.
Navigation System
Both models feature intelligent navigation systems, although with important differences. The Roborock Qrevo CurvX integrates SmartPlan 2.0, the most advanced version of Roborock's intelligent planning software, which optimises cleaning routes and adapts the robot's behaviour according to the type of dirt and surface detected.
The Qrevo Slim incorporates SmartPlan 1.0, an earlier version but equally effective for most homes. Both systems allow precise mapping, creation of no-go zones and personalised scheduling. It's important to note that neither model includes stain recognition using artificial intelligence, a feature that some users might miss in the premium segment.
Autonomy and Battery
Autonomy is another differentiating factor in this robot vacuum comparison. The Roborock Qrevo CurvX features a 6400 mAh battery that provides up to 220 minutes of continuous operation, sufficient to clean large homes without the need for intermediate recharging.
The Qrevo Slim has a 5200 mAh battery that offers 180 minutes of autonomy. Although lower in capacity, it remains a more than respectable figure for medium-sized homes, covering approximately between 150 and 200 square metres depending on the selected cleaning mode. The 40-minute difference can be decisive if you live in a large house or one with multiple floors.
Smart Features
Regarding obstacle-climbing capability, the Roborock Qrevo CurvX demonstrates its technical superiority by being able to overcome height differences of between 30 and 40 mm, a particularly useful feature for thick carpets and door thresholds. The Qrevo Slim, with a 20 mm capability, remains competent for most domestic situations, although it may have difficulties with very high-pile carpets or more pronounced transitions.
Neither model incorporates a robotic arm nor its own voice assistant, features that are reserved for the brand's ultra-premium range models.
Multifunctional Cleaning Base
Both robot vacuums include a multifunctional cleaning base, although with important technological differences. The Roborock Qrevo CurvX integrates the 3.0 watertight tray self-cleaning system, the most advanced version that guarantees a hermetic seal and deeper cleaning of the station.
The Qrevo Slim incorporates the 1.0 watertight system, an earlier but functional version that fulfils basic automatic maintenance tasks. Regarding storage capacities, the Qrevo CurvX has a 258 ml dust bin compared to the Qrevo Slim's 220 ml, which means fewer manual emptyings in the more advanced model.
Dimensions
Interestingly, both models share the same diameter of 353 mm, which means they will occupy the same floor space and have similar capabilities for accessing tight spaces. The difference lies in height: the Roborock Qrevo CurvX measures 79.8 mm tall, whilst the Qrevo Slim reaches 82 mm.
This difference of barely 2.2 mm may seem insignificant, but in practice it can determine whether or not the robot fits under certain low furniture, sofas or beds. If you have furniture with little clearance, the Qrevo CurvX offers a slight advantage in this respect, although both are relatively compact for robots with their features.
Conclusion: Which to Choose?
After analysing the differences between these two models, choosing the best robot vacuum 2025 for you will depend on your specific needs and budget.
Choose the Roborock Qrevo CurvX if you're looking for:
- Maximum suction power (22000 Pa) for thick carpets or pets with heavy shedding
- Greater autonomy (220 minutes) for large homes or intensive cleaning
- The most advanced self-cleaning system (3.0 watertight)
- Better capability to overcome obstacles up to 40 mm
- The latest generation DuoDivide anti-tangle brush
- SmartPlan 2.0 technology with advanced route optimisation
The Roborock Qrevo Slim is ideal for:
- Medium-sized homes where 180 minutes of autonomy is sufficient
- Users seeking a balance between performance and price
- Homes without very thick carpets or obstacles exceeding 20 mm
- Those who prioritise a reliable Roborock robot vacuum without needing the latest innovations
- Tighter budgets without sacrificing brand quality
In short, the Roborock Qrevo CurvX represents the brand's most recent technological evolution, with substantial improvements in power, autonomy and self-cleaning systems. The Qrevo Slim, for its part, remains a very competent option that will meet the expectations of most users. The price difference between both models should be the deciding factor if the Qrevo Slim's features cover your needs, as it offers excellent value for money within the Roborock range.
