Introduction
The DJI Romo S (White) and the Roborock Qrevo Curv 2 Pro represent two high-end propositions within the 2025 robot vacuum market. DJI, known primarily for its drones, has made the leap into the home cleaning sector with a model that integrates its experience in navigation and artificial vision. Roborock, a global reference in this segment, presents an evolution of its Qrevo line with proven and refined technology.
Both units incorporate a multifunctional base with mop washing and drying, 25,000 Pa suction power and advanced AI navigation systems. They are designed for homes seeking complete cleaning automation, although they present important differences in battery life, height and some functional details that may influence the choice depending on the specific needs of each household.
Power and Suction
The 25,000 Pa of suction places these two robots in the highest power segment of the market. This figure is more than sufficient for medium-pile carpets and floors with ingrained dirt.
Regarding the brushing system, the DJI Romo S features a Dividid main brush with anti-tangle technology, whilst the Roborock Qrevo Curv 2 Pro is equipped with its DuoDivide Antienredos system. The latter pushes hairs towards the central gap to facilitate direct suction and minimise tangles. Both designs are intended for homes with pets, although the technical approach differs slightly.
Both models raise the main brush during mopping to prevent wet dirt from adhering to the bristles. They also incorporate an extendable side brush to improve cleaning in corners, and both feature a dual anti-tangle side brush. Neither raises the side brush during mopping nor includes a specific brush for skirting boards.
Mopping
Both robots use two rotating mops that extend to reach the edges, a fundamental feature for achieving complete mopping right up to the corners. The mops are raised during dry vacuuming, although the Roborock specifies a lift of between 7 and 17 mm depending on the surface type.
The most relevant difference in this section lies in the mop washing. The Roborock Qrevo Curv 2 Pro washes the mops with hot water, which improves the removal of grease and adhered dirt. The DJI Romo S performs washing with cold water. In both cases, drying is carried out with hot air to speed up the process and prevent bad odours.
The self-cleaning system for the washing tray also presents differences: the DJI incorporates an automatic nozzle, whilst the Roborock uses its 3.0 system. The Roborock can automatically remove the mops at the base when only vacuuming is desired, a function that the DJI does not specify.
Both units integrate dirt detection on both the mops and the floor, allowing automatic re-mopping in areas that require it. Neither model mops the floor with hot water, only using cold water during the cleaning process.
Navigation System
The DJI Romo S uses a solid-state LiDAR, whilst the Roborock Qrevo Curv 2 Pro features a retractable LiDAR. Both technologies guarantee precise mapping and efficient navigation, although the Roborock's retractable system allows for a reduction in the robot's overall height.
In artificial vision, the DJI integrates an AI camera and the Roborock is equipped with dual AI cameras, which potentially improves object recognition from different angles. The Roborock specifies that it recognises up to 200 different types of obstacles and confirms specific pet detection. The DJI does not detail this data.
Both robots feature a front 3D laser sensor for real-time obstacle avoidance, night vision LED and remote camera access. The Roborock incorporates its SmartPlan 3.0 system for intelligent AI cleaning, whilst the DJI also offers intelligent cleaning without specifying the algorithm version. Both recognise stains using AI for localised mopping. Neither detects curtains to avoid tangles.
Battery Life and Battery
Battery life marks one of the most significant differences in this robot vacuum comparison. The Roborock Qrevo Curv 2 Pro reaches 290 minutes of continuous operation thanks to its 6,400 mAh battery. The DJI Romo S, with 5,000 mAh, offers 180 minutes of battery life.
In practice, this 110-minute difference can prove decisive in large homes or those with complex layouts. The Roborock model covers large surfaces without the need for intermediate recharges, whilst the DJI may require a pause in homes of more than 150 square metres if a complete clean with mopping is programmed.
Smart Functions
The DJI Romo S overcomes thresholds of up to 20 mm, whilst the Roborock Qrevo Curv 2 Pro can cross simple thresholds, although it does not specify the exact height. This capability is useful for moving between rooms with different floor levels or overcoming sliding door guides.
The Roborock confirms the presence of its own voice assistant in addition to compatibility with Alexa and Google Home. The DJI is compatible with external voice assistants, although it does not detail whether it incorporates its own assistant. Neither model includes a robotic arm.
Multifunctional Cleaning Base
The bases of these robot vacuums integrate the complete functions of auto-emptying, washing and drying. The DJI's dust bag has a capacity of 2.4 litres, whilst the Roborock's reaches 2.5 litres. Minimal differences that are barely noticeable in daily use, as both allow several weeks without changing the bag.
The clean water tanks are identical: 4 litres in both cases. The dirty water tank differs slightly: 3.2 litres in the DJI compared to 3 litres in the Roborock. These capacities guarantee complete cleaning of medium-sized homes without the need to refill or empty during the process.
The DJI Romo S incorporates a detergent tank in the base, which allows cleaning product to be added and dispensed during mop washing. The Roborock Qrevo Curv 2 Pro does not include this function. Neither offers integrated plumbing connection nor an optional kit for it, so they require manual filling and emptying of the tanks.
Dimensions
The robot's height marks an important functional difference. The Roborock Qrevo Curv 2 Pro measures 79.8 mm, whilst the DJI Romo S reaches 98 mm. Those additional 18 mm may prevent the DJI from accessing under certain furniture, sofas or beds with little clearance from the floor.
The diameter is practically identical: 351 mm on the DJI and 352 mm on the Roborock. Both navigate without problems through standard spaces and corridors.
The bases present similar dimensions. The DJI measures 453 mm wide, 440 mm tall and 425 mm deep. The Roborock has 450 mm in all three dimensions, resulting in an almost perfect cube. It is advisable to reserve a space of at least 50 cm in each direction to facilitate the robot's access to the base.
Real-World User Experience
For large homes, the Roborock Qrevo Curv 2 Pro offers clear advantages thanks to its 290 minutes of battery life. Homes of more than 150 square metres or layouts with many rooms benefit from this greater battery capacity, which allows deep cleaning to be completed without interruptions.
If the home has low furniture, the Roborock accesses better underneath them thanks to its 79.8 mm height. The DJI, at 98 mm, may be left out of tighter spaces.
In homes with pets, both robots offer effective anti-tangle brush systems. The 25,000 Pa power is more than sufficient for dog or cat hair on any type of floor. The Roborock specifies pet recognition, which may translate into automatic cleaning adjustments in areas where the animals usually are.
The Roborock's hot water mop washing improves results in kitchens or areas with grease. The DJI compensates for this difference with its detergent tank, which adds product during mop washing. These are two different approaches to achieving cleaner mops.
The Roborock's automatic mop removal facilitates alternating between vacuuming and mopping without manual intervention. The user programmes dry vacuuming and the robot removes the mops at the base before starting the task.
Conclusion: Which to Choose?
Choose the DJI Romo S (White) if: you are looking for a high-end robot vacuum with an integrated detergent tank in the base, you value DJI's technological proposition in its entry to the sector and your home does not exceed 120-140 square metres.
