Introduction
The Roborock Qrevo Master and Roborock QV 35A represent two distinct approaches within Roborock's robot vacuum lineup. The Qrevo Master launched in 2024 as a premium model packed with advanced features, whilst the QV 35A arrived in 2025 as a more streamlined option. Both models share the same robust 5,200 mAh battery delivering 180 minutes of runtime, making them suitable for medium to large homes. The Qrevo Master pushes boundaries with 10,000 Pa suction power and dual rotating mops, targeting users who want comprehensive automation. The QV 35A offers a more accessible entry point with 8,000 Pa suction and simplified navigation, appealing to those seeking reliable performance without every premium feature.
Power and Suction
The Qrevo Master delivers 10,000 Pa of suction force compared to the QV 35A's 8,000 Pa. That 2,000 Pa difference becomes noticeable when dealing with embedded dirt in carpets or fine dust on hard floors. The Qrevo Master employs a dual brush system that works in tandem to agitate and lift debris more effectively, whilst the QV 35A relies on a single brush configuration. This dual setup proves particularly useful on medium-pile carpets where a single brush might struggle.
What sets the Qrevo Master apart is its ability to lift the main brush during mopping sessions. This prevents a wet brush from dragging across already-cleaned floors and avoids cross-contamination between vacuuming and mopping zones. The QV 35A lacks this feature, meaning the brush remains in contact with the floor throughout mopping.
The Qrevo Master includes an extensible side brush that reaches further into corners and along skirting boards. In practice, this means better edge coverage without requiring multiple passes. The QV 35A compensates with anti-tangle technology on its side brush, reducing the frequency of hair wrap-around that requires manual intervention. Neither model offers side brush elevation during mopping, so both keep their side brushes active throughout the cleaning cycle.
Mopping Performance
Both models use rotating mop systems with 10 mm lift capability, allowing them to clear low-pile rugs and transition between hard floors and carpets. The Qrevo Master's mops can extend outwards to reach closer to walls and furniture legs, improving edge coverage during mopping runs. The QV 35A's mops maintain a fixed position, leaving a small gap along perimeters.
The Qrevo Master incorporates dirt detection sensors that monitor both mop cleanliness and floor soiling levels. When the system detects stubborn marks, it automatically increases scrubbing intensity or makes additional passes. This adaptive approach means less manual intervention for problem areas. The QV 35A operates with preset mopping patterns without real-time adjustment based on floor conditions.
Neither model offers automatic mop removal at the base station, so both require manual detachment if you want a vacuum-only session. Both use cold water for floor mopping, keeping things simple without heated water tanks in the robot itself.
Base Station Capabilities
The base stations share identical water tank capacities: 4 litres for clean water and 3.5 litres for dirty water, with 2.7-litre dust bags. The fundamental difference lies in mop maintenance. The Qrevo Master washes mops with hot water at approximately 60°C, loosening oils and sticky residues more effectively than cold water alone. It then dries the mops using heated air, significantly reducing drying time and minimising bacterial growth. The QV 35A washes with cold water and relies on ambient air drying, which takes longer and may leave mops slightly damp between cleaning sessions.
The Qrevo Master adds automatic base tray cleaning, periodically flushing the washing area to prevent buildup and odours. The QV 35A requires manual tray maintenance. Neither model includes a detergent dispenser, UV sterilisation, or plumbing connection options, though neither offers the optional plumbing kit as an add-on.
Navigation System
Both robots feature 3.0 LiDAR turrets for room mapping and obstacle avoidance, creating accurate floor plans that improve with each cleaning cycle. The Qrevo Master layers on a dual AI camera system combined with a front-mounted 3D laser sensor, creating a comprehensive obstacle detection network. This setup recognises 62 different object types, from shoes and cables to furniture legs and pet toys. The QV 35A lacks cameras and 3D sensors, relying primarily on LiDAR and basic proximity detection. The number of obstacles it can identify isn't specified.
Pet owners will appreciate the Qrevo Master's specific pet recognition capability, allowing it to identify and carefully navigate around animals. The remote camera access lets you check on pets whilst away from home. The built-in LED provides night vision functionality, useful for late-evening cleaning sessions or monitoring dark corners. The QV 35A offers none of these vision-based features.
Both models run SmartPlan 1.0 for intelligent cleaning routines, learning room layouts and suggesting optimal schedules. The Qrevo Master operates on the RR Mason 11.0 processor, whilst the QV 35A's specific chipset isn't detailed. Neither model includes AI-powered stain recognition that would trigger spot-cleaning modes automatically.
Battery and Autonomy
Identical 5,200 mAh batteries power both robots, providing 180 minutes of continuous operation. This runtime suits homes up to approximately 200-250 square metres on a single charge. Charging times aren't specified for either model. The matched battery specifications mean both handle large floor plans equally well, returning to base for recharging mid-clean if necessary before resuming where they left off.
Smart Features
Both robots manage 20 mm obstacle climbing, clearing typical door thresholds, thick rugs, and minor floor transitions without assistance. The Qrevo Master includes a built-in voice assistant for direct robot interaction without requiring a smartphone. The QV 35A lacks this onboard assistant but both models integrate with external voice platforms like Amazon Alexa and Google Home for basic commands.
Dimensions
The QV 35A measures 96.5 mm tall compared to the Qrevo Master's 103 mm height. That 6.5 mm difference allows the QV 35A to squeeze under slightly lower furniture, potentially accessing spaces the Qrevo Master cannot reach. Both share a 353 mm diameter, typical for robot vacuums and narrow enough for most room layouts. The base stations measure identically at 340 mm wide, 521 mm tall, and 487 mm deep, requiring similar floor space in laundry rooms or utility areas.
The Qrevo Master carries a 220 ml dust bin whilst the QV 35A offers 330 ml capacity. In practice, this means the QV 35A can handle longer vacuuming sessions before triggering a return to base for emptying, useful in particularly dusty environments. Both include 80 ml water tanks for mopping operations.
Real-World Usage
For homes with pets, the Qrevo Master's higher suction power, dual brush system, and pet recognition capabilities make it better equipped to handle fur and track animal movements safely. The anti-tangle side brush on the QV 35A does help with hair management, but the overall package favours the Qrevo Master for pet households.
In larger properties exceeding 150 square metres, both robots manage well thanks to identical battery capacity. The Qrevo Master's dirt detection ensures thorough cleaning without multiple manual passes, whilst the QV 35A requires more user oversight to achieve similar results in heavily soiled areas.
The Qrevo Master's hot water mop washing and heated drying make it more suitable for homes where mopping happens frequently, maintaining hygiene standards without daily manual mop maintenance. The QV 35A works adequately for light mopping needs but may develop odours if used intensively without regular manual mop cleaning.
For those with low-clearance furniture, the QV 35A's reduced height grants access to more spaces. The Qrevo Master's extra sensors and cameras help it navigate complex room layouts with less risk of getting stuck, compensating somewhat for its additional height.
