Introduction
We are looking at two Roborock offerings launched in 2025 that represent very different philosophies within the brand's catalogue. The Roborock Qrevo CurvX is positioned as a premium model with advanced technology and solutions aimed at the most demanding cleaning. The Roborock QV 35A, on the other hand, adopts a more accessible approach whilst maintaining the brand's essential features.
The Qrevo CurvX is designed for users seeking total automation and who don't want to worry about difficult corners or constant base maintenance. The QV 35A is more suitable for those who prioritise a balanced quality-price ratio without sacrificing basic mopping and self-emptying functions.
Power and Suction
The most obvious difference in this robot vacuum comparison is suction power. The Roborock Qrevo CurvX reaches 22000 Pa, a figure that triples the 8000 Pa of the Roborock QV 35A. This difference translates into greater capacity to extract ingrained dirt from carpets and to vacuum heavier particles or stuck-on debris.
The brushing system also sets them apart. The CurvX integrates the DuoDivide anti-tangle brush, designed to push hair towards the central suction gap and reduce tangles. This model also includes an extendable side brush that allows better reach into corners. The QV 35A, meanwhile, features a conventional simple brush without anti-tangle technology on the main roller, although it does have an anti-tangle side brush.
Both maintain the side brush without elevation during mopping. The Qrevo CurvX does lift its main brush when mopping, preventing it from getting wet and improving mopping efficiency. The QV 35A does not have this function.
Mopping
Both models employ a two rotating mop system, but the similarities end there. The Roborock Qrevo CurvX incorporates FlexiArm mop extension, which allows it to mop edges and corners with greater precision. The QV 35A does not extend its mops.
Mop lifting works on both, although with different ranges: the CurvX can lift them between 7 and 17 mm, whilst the QV 35A raises them up to 10 mm. This allows both to pass over carpets without wetting them, although the CurvX offers greater adaptation range.
Mop washing marks a considerable difference. The Qrevo CurvX washes the mops with hot water at 80°C and dries them with hot air at 45°C, which speeds up drying and reduces bacterial proliferation. The QV 35A washes with cold water and dries with cold air, a slower and less effective process for eliminating organic residue.
The CurvX adds dirt detection on both the mops and the floor, automatically adjusting the cleaning process according to what it detects. The QV 35A lacks this function. Neither allows automatic mop removal at the base to perform vacuum-only tasks.
Navigation System
The Roborock Qrevo CurvX features a retractable LIDAR combined with dual AI camera, front 3D laser sensor and LED for night vision. This setup allows it to recognise up to 108 types of obstacles, including pets, and offers remote camera access from the app. The SmartPlan 2.0 artificial intelligence and RR Mason 11.0 processor manage cleaning adaptively.
The Roborock QV 35A uses a LIDAR 3.0 turret without AI camera or 3D laser sensor. It has obstacle avoidance, but without the level of detail of the CurvX. It does not recognise pets nor allows remote camera access. It integrates SmartPlan 1.0, a less advanced version of Roborock's artificial intelligence.
In practice, the CurvX is more precise at identifying small objects and adapting to complex environments. The QV 35A performs well in tidy spaces, but may have more difficulty with unexpected obstacles.
Autonomy and Battery
The Qrevo CurvX is equipped with a 6400 mAh battery that provides up to 220 minutes of autonomy. The QV 35A features 5200 mAh and reaches 180 minutes. The 40-minute difference may be relevant in large homes or when performing complete cleans with various mopping modes.
The CurvX's greater suction power could consume more energy in maximum mode, but its larger battery compensates for this consumption. The QV 35A, with lower power, maintains sufficient autonomy for most medium-sized homes.
Smart Functions
The Roborock Qrevo CurvX can overcome obstacles up to 30-40 mm in height, which allows it to navigate thick carpets, high thresholds or cables without getting stuck. The Roborock QV 35A stops at 20 mm, sufficient for most everyday situations but more limited when facing pronounced level changes.
The CurvX incorporates a simple voice assistant that allows basic commands without going through the app. The QV 35A does not include this function. Neither has a robotic arm.
Multifunction Cleaning Base
Both robots include a multifunction base with self-emptying, mop washing and drying. Tank capacities are similar: 4 litres of clean water in both cases, and 3 litres of dirty water in the CurvX versus 3.5 litres in the QV 35A. The dust bag has 2.5 litres in the CurvX and 2.7 litres in the QV 35A.
The fundamental difference is in tray self-cleaning. The Qrevo CurvX features the 3.0 system already installed from the factory, which automatically cleans the tray where the mops are washed, preventing dirt accumulation and bad odours. The QV 35A does not have this function, which requires manual tray cleaning more frequently.
Neither includes a detergent tank, UV disinfection nor connection to water pipes.
Dimensions
The diameter is identical on both: 353 mm. Height marks an important difference. The Roborock Qrevo CurvX measures 79.8 mm, which allows it to slip under low furniture, beds or sofas more easily. The Roborock QV 35A reaches 96.5 mm, a height that may limit its access to certain spaces.
Base dimensions also vary. The CurvX's is more compact and square: 450 mm width, height and depth. The QV 35A's has 340 mm width, 521 mm height and 487 mm depth, occupying a somewhat different space depending on where it is placed.
Real-World Experience
The Roborock Qrevo CurvX is designed for large homes where autonomy, power and deep cleaning without constant intervention are needed. Its ability to overcome high obstacles, mop edges with precision and wash mops with hot water makes it a solid option for homes with pets, children or heavy traffic. The reduced height allows it to access under more furniture, something appreciated in spaces with low furniture.
The Roborock QV 35A is more suitable for medium-sized flats without very thick carpets or complicated obstacles. The lower suction power may be noticeable on long-pile carpets, but on hard floors and parquet it offers satisfactory results. Mopping with cold water performs adequately, although it requires more attention to base maintenance.
The CurvX's tray self-cleaning notably reduces manual maintenance. On the QV 35A it's advisable to check the tray more frequently to avoid residue accumulation.
Conclusion: Which to Choose?
Choose the Roborock Qrevo CurvX if you're looking for the best robot vacuum 2025 within Roborock's catalogue, need maximum suction power, have pets or thick carpets, value automatic base cleaning and want remote camera access. Also if your home has low furniture and you need a robot that can slip under them without problems. It's the option for those who prioritise total automation and minimum maintenance.
Choose the Roborock QV 35A if you're looking for a Roborock robot vacuum with essential functions well executed at a more competitive price. It's suitable for medium-sized flats, hard floors or parquet, and users who don't need advanced object recognition or mop extension. The lower height may be an inconvenience under low furniture, but in other situations it performs without problems. Ideal for those who value Roborock's reliability without needing all the premium features.
