Introduction
The Roborock Qrevo Master and the Roborock QV 35S represent two consecutive generations of high-end robot vacuum cleaners within Roborock's catalogue. The former arrived on the market in 2024, whilst the latter was launched in 2025. Although they share suction power, battery capacity and many fundamental features, the technical differences between them are significant and mark different paths in terms of performance and price.
The Qrevo Master is positioned as a premium model with advanced artificial intelligence capabilities and a more comprehensive mopping system. The QV 35S, more recent, opts to simplify some functions whilst maintaining solid performance. Both are designed for households seeking complete cleaning automation, although the user profile they target presents important nuances.
Power and Suction
Both units achieve 10,000 Pa of suction power, a figure that places them in the high-end market segment. The 5,200 mAh battery is also identical, providing 180 minutes of autonomy under optimal conditions.
The differences appear in the brushing system. The Qrevo Master mounts a dual DuoDivide brush, a design that favours hair capture by pushing it towards the centre for suction. This system notably reduces tangles. The QV 35S uses a single brush, a more traditional configuration but equally effective for most situations.
The Qrevo Master's main brush can be raised during mopping, preventing it from getting wet and allowing more hygienic cleaning. The QV 35S lacks this function. As for the side brush, the Qrevo Master integrates an extendable arm that reaches corners better, whilst the QV 35S compensates with an anti-tangle design on its side brush. Neither raises the side brush during mopping.
For households with long-haired pets, the Qrevo Master's dual brush makes a difference. In homes without this specific need, the QV 35S's anti-tangle side brush may prove more practical for daily maintenance.
Mopping
The mopping system presents substantial differences. The Qrevo Master uses rotating mops with extension capability to reach edges and skirting boards, a function the QV 35S does not incorporate. This extension allows more thorough mopping of room perimeters.
Both models raise the mops up to 10 mm when they detect carpets, protecting textile surfaces. However, the Qrevo Master goes further by integrating dirt detection both on the mops themselves and on the floor. This allows it to reinforce cleaning in particularly dirty areas or pass again if it detects that the mops need a fresh wash. The QV 35S lacks these sensors.
Water temperature marks another relevant difference. The Qrevo Master's base washes mops with hot water, which improves the removal of grease and stubborn stains. The QV 35S performs this washing with cold water, less effective against complex dirt but sufficient for routine maintenance.
Drying also differs: hot air in the Qrevo Master versus cold air in the QV 35S. Hot air drying accelerates the process and reduces the risk of bad odours or bacterial growth. Additionally, the Qrevo Master includes self-cleaning of the washing tray, a function absent in the QV 35S which requires periodic manual cleaning.
Neither automatically removes the mops at the base when only vacuuming is desired, something that some competitors in a similar range do offer.
Navigation System
Both robots employ LiDAR 3.0 turret to map the home and plan efficient routes. Both feature obstacle avoidance and SmartPlan 1.0, Roborock's intelligent cleaning system.
The Qrevo Master stands out for its additional equipment: dual AI camera, front 3D laser sensor and night vision LED. These cameras allow remote access, a useful function for home surveillance when you're not present. It recognises up to 62 different types of obstacles, including pets specifically. The 3D sensor improves precision in detecting small or low-height objects.
The QV 35S dispenses with AI camera, front 3D laser sensor and night LED. It does not offer remote access or specific pet recognition. Nor is the number of obstacles it can identify specified. This simplification reduces capabilities but also eliminates privacy-related concerns that some people have regarding cameras in the home.
The Qrevo Master's processor is the RR Mason 11.0, whilst the QV 35S's chip is not detailed. In practice, the Qrevo Master offers more sophisticated and adaptive navigation, especially in homes with pets or many obstacles.
Autonomy and Battery
With 5,200 mAh and 180 minutes of autonomy, both robots can cover large surfaces in a single charge. This capacity is sufficient for homes of up to 200 square metres without the need for intermediate recharging.
No data is specified regarding charging time or maximum recommended surface area for either model. Battery management will depend on the selected cleaning mode: maximum power reduces autonomy whilst eco modes extend it.
Smart Functions
Both the Qrevo Master and the QV 35S overcome obstacles up to 20 mm in height, a useful capability for navigating cables, small unevenness or thick carpet edges.
The Qrevo Master incorporates its own voice assistant, allowing direct interaction with the robot without depending on external applications. The QV 35S does not have this function. Both are compatible with external assistants such as Alexa or Google Home.
Multifunction Cleaning Base
The bases of both models share dimensions (340 x 521 x 487 mm) and tank capacities: 2.7-litre dust bag, 4-litre clean water tank and 3.5-litre dirty water tank. These capacities guarantee several weeks of autonomy without manual intervention.
Both bases perform auto-emptying of the dust bin and mop washing, but with the temperature differences already mentioned. The Qrevo Master's hot air drying versus the QV 35S's cold air is a clear advantage in terms of hygiene and speed.
The Qrevo Master's self-cleaning of the washing tray significantly reduces maintenance. The QV 35S requires periodic manual cleaning of this area, a simple task but one that adds a responsibility for the user.
Neither includes UV disinfection, detergent tank nor integrated connection to plumbing. Nor do they offer an optional kit for this connection. Automatic mop changing is also not present in either.
Dimensions
The diameter is identical in both: 353 mm. The height presents an important difference: the QV 35S measures 96.5 mm versus the Qrevo Master's 103 mm. These 6.5 mm can make the difference in homes with low furniture. The QV 35S will access more easily under sofas, beds or wardrobes with little separation from the floor.
The robot's dust bin also varies: 220 ml in the Qrevo Master and 330 ml in the QV 35S. This means the QV 35S can vacuum for longer before needing emptying, although in practice both return regularly to the base for auto-emptying. The robot's water tank is 80 ml in both cases.
The bases have identical measurements, occupying the same space in the home.
Real-World User Experience
In large homes with pets, the Qrevo Master offers clear advantages: its dual brush handles hair better, specific pet detection avoids accidents and the cameras allow remote surveillance. Mopping with mop extension, hot water washing and dirt detection provides superior results in deep cleaning.
For homes with low furniture, the QV 35S proves more practical thanks to its lower height. Its larger dust bin also benefits those with homes with heavy traffic or accumulated dust. The anti-tangle side brush simplifies maintenance if there are no long-haired pets.
The absence of cameras in the QV 35S can be an advantage for users concerned about privacy. Although Roborock is a reliable brand, some people prefer to avoid devices with cameras in the home.
Hot air drying and the Qrevo Master's tray self-cleaning considerably reduce maintenance tasks. In the QV 35S it's advisable to check and clean the tray every week to avoid dirt accumulation.
Both models handle hard floors and parquet well. The 10 mm mop lift protects medium-thickness carpets, although for very thick carpets it may prove insufficient.
Conclusion: Which to Choose?
Choose the Roborock Qrevo Master if: you're seeking the maximum level of automation and features. Ideal for homes with long-haired pets, thanks to its dual brush and specific recognition. Mopping with mop extension, hot water and dirt detection provides professional results. Tray self-cleaning and hot air drying minimise maintenance. Cameras with remote access add surveillance functionality. It's the option for those seeking the best robot vacuum cleaner 2025 without compromises.
Choose the Roborock QV 35S if: you prioritise accessing under low furniture thanks to its 96.5 mm height. Its larger dust bin (330 ml) proves practical in homes with lots of dust. The anti-tangle side brush facilitates maintenance if you don't live with long-haired pets. It's a solid option for those who prefer to do without cameras for privacy reasons. It offers a balance between features and simplicity, maintaining Roborock quality at a presumably more competitive price than the Qrevo Master.
This Roborock robot vacuum cleaner comparison shows two different philosophies: maximum technology versus practical efficiency. The differences between both models are sufficiently significant for the choice to depend on specific needs rather than generic preferences.
