Introduction
The Roborock Qrevo Edge S5A, Roborock Qrevo Master, and Roborock S8 MaxV Ultra represent three distinct approaches within Roborock's 2024 lineup. Whilst all three share the brand's reputation for reliability and advanced multifunctional bases, they differ significantly in suction power, navigation capabilities, and overall sophistication. The Qrevo Edge S5A stands out with its exceptional suction strength, whilst the Qrevo Master and S8 MaxV Ultra focus on enhanced artificial intelligence and object recognition. Each model caters to different household needs, from those prioritising raw cleaning power to users seeking comprehensive smart home integration and advanced navigation.
Power and Suction
The most striking difference lies in suction capability. The Qrevo Edge S5A delivers 18,500 Pa, making it nearly twice as powerful as the Qrevo Master and S8 MaxV Ultra, both rated at 10,000 Pa. This substantial difference translates to superior performance on carpets and when dealing with embedded dirt or pet hair.
Regarding brush systems, the S5A employs Roborock's DuoDivide Anti-tangle design, which pushes hair towards the central suction area to minimise tangling. The Qrevo Master and S8 MaxV Ultra use standard dual brush configurations. Interestingly, the S5A also features an anti-tangle side brush, a detail absent from its competitors.
Where the S5A falls behind is brush elevation. Whilst the Qrevo Master and S8 MaxV Ultra can lift their main brushes during mopping to avoid cross-contamination, the S5A cannot. This becomes relevant when transitioning between hard floors and carpets during a combined clean. All three models feature extendable side brushes for improved edge cleaning, but none can elevate their side brushes.
Mopping
The mopping approach varies between models. The Qrevo Edge S5A and Qrevo Master both use dual rotating mops, whilst the S8 MaxV Ultra relies on a vibratory mopping system. The S5A and Qrevo Master extend their mops to reach edges more effectively, whereas the S8 MaxV Ultra uses a mini lateral mop for border cleaning—a different design philosophy achieving similar results.
Mop elevation differs notably. The S5A and Qrevo Master can raise their mops 10 mm when encountering carpets, but the S8 MaxV Ultra goes further with 20 mm of lift. This extra clearance provides better protection for medium-pile rugs.
All three models wash their mops with hot water at the base and dry them using warm air, preventing odours and bacterial growth. They also detect dirt on both the mops and the floor, adjusting cleaning intensity accordingly. However, none of the models can automatically remove their mops at the base for vacuum-only sessions—manual intervention remains necessary.
Navigation System
Navigation capabilities reveal a clear hierarchy. The Qrevo Edge S5A uses LiDAR mapping and obstacle avoidance but lacks AI cameras or 3D laser sensors. This makes it competent for structured environments but less adaptable to complex obstacle scenarios.
The Qrevo Master introduces dual AI cameras, a frontal 3D laser sensor, and LED night vision. It recognises 62 different objects and can identify pets specifically. Remote camera access allows users to check on their home through the robot, adding a security dimension beyond cleaning.
The S8 MaxV Ultra builds upon this with recognition of 73 objects and exclusive AI-powered stain detection, enabling it to identify and focus on specific dirty areas autonomously. Like the Qrevo Master, it offers remote camera access and LED illumination for low-light conditions.
For households with pets or numerous floor-level objects, the enhanced perception of the Qrevo Master and S8 MaxV Ultra provides tangible benefits. The S5A remains effective but requires a tidier environment for optimal performance.
Battery and Autonomy
All three robots share identical 5,200 mAh batteries and 180-minute runtime. This consistency means they can handle similar-sized homes—approximately 200-250 square metres—on a single charge. Battery capacity doesn't differentiate these models; the real-world cleaning coverage will depend more on suction settings and mopping frequency.
Smart Functions
Each model can climb obstacles up to 20 mm, handling typical door thresholds and minor floor transitions without difficulty. None features a robotic arm or similar advanced manipulation technology.
The Qrevo Master and S8 MaxV Ultra include Roborock's proprietary voice assistant, allowing direct voice commands to the robot itself. The Qrevo Edge S5A lacks this feature but still integrates with external assistants like Alexa and Google Home, as do the other two models. In practice, this means the S5A requires a smart speaker for voice control, whilst the others respond independently.
All three run Roborock's Mason 11.0 processor and SmartPlan AI for intelligent cleaning routines, ensuring efficient room sequencing and coverage patterns.
Multifunctional Base
Every model includes a multifunctional base with auto-emptying, mop washing with hot water, and warm air drying. The key differences emerge in maintenance and capacity.
The Qrevo Edge S5A features the latest 2.0 self-cleaning system for the washing tray, reducing manual maintenance. The Qrevo Master uses version 1.0 of this system, whilst the S8 MaxV Ultra lacks automatic tray cleaning entirely—requiring periodic manual attention.
Only the S8 MaxV Ultra includes a detergent dispenser, automatically adding cleaning solution during mop washing. The Qrevo models rely on water alone, though this often suffices for routine maintenance.
Dust bag capacity favours the Qrevo models at 2.7 litres versus 2.5 litres for the S8 MaxV Ultra. Water tanks are identical across all three: 4 litres clean and 3.5 litres dirty. None offers integrated plumbing connections, and no optional kit exists for any model.
Dimensions
The robots themselves measure very similarly. The Qrevo Edge S5A is 352 mm in diameter and 98 mm tall, making it the lowest profile of the three. The Qrevo Master and S8 MaxV Ultra both measure 353 mm across and 103 mm high. That 5 mm height difference can matter when navigating under low furniture—the S5A may access spaces the others cannot.
Base dimensions diverge more substantially. The Qrevo models share identical footprints: 340 mm wide, 521 mm tall, and 487 mm deep. The S8 MaxV Ultra takes a different form at 409 mm wide, 470 mm tall, and 419 mm deep—wider but shorter and less deep. Consider your available floor space when choosing, as the Qrevo bases extend further from the wall.
Real-World Usage
For homes with thick carpets or heavy pet shedding, the Qrevo Edge S5A's superior suction and anti-tangle brush design deliver noticeable advantages. Its lower profile also benefits households with furniture clearances around 10 cm. However, the absence of AI cameras means you'll need to maintain relatively clutter-free floors.
The Qrevo Master suits users wanting comprehensive smart features without the premium of the S8 MaxV Ultra. Its dual cameras and 62-object recognition handle complex environments well, whilst the proprietary voice assistant adds convenience. The upgraded base self-cleaning reduces maintenance frequency.
The S8 MaxV Ultra targets those seeking maximum intelligence. With 73-object recognition and AI stain detection, it adapts to changing conditions more effectively. The detergent dispenser enhances mopping results, whilst the higher mop lift protects thicker rugs. The trade-off comes in base maintenance, as the washing tray requires manual cleaning.
All three handle hard floors, parquet, and low-pile carpets competently. The 180-minute battery makes them suitable for larger homes, though the S5A's larger onboard dust bin (325 ml versus 220-270 ml) means fewer interruptions during extended cleaning sessions.
Conclusion: Which to Choose?
Choose the Roborock Qrevo Edge S5A if: you prioritise raw suction power above all else, have significant carpeting or multiple pets, need to clean under low furniture regularly, or prefer a simpler system without cameras. The enhanced base self-cleaning 2.0 system also reduces your maintenance workload. Best for homes where cleaning performance matters more than navigation sophistication.
Choose the Roborock Qrevo Master if: you want balanced performance with strong AI capabilities at a middle-ground price point. The dual cameras and 62-object recognition handle busy households with children or pets, whilst the voice assistant and remote camera access add practical convenience.
