Introduction
The Roborock Qrevo Curv and Roborock Qrevo Edge S5A represent two premium offerings from the world's leading robot vacuum manufacturer, both launched in 2024. These aren't entry-level models—they're positioned at the high end of Roborock's range, sharing the same impressive 18,500 Pa suction power and featuring multifunctional bases with hot water mop washing and hot air drying. Both incorporate the DuoDivide anti-tangle brush system, dual rotating mops with edge extension, and the SmartPlan 2.0 intelligent cleaning algorithm powered by the RR Mason 11.0 processor.
The distinction between these two models lies primarily in their navigation intelligence, obstacle avoidance capabilities, battery capacity, and physical dimensions. The Qrevo Curv positions itself as the more technologically advanced option with dual AI cameras and enhanced obstacle recognition, whilst the Qrevo Edge S5A offers a more compact base footprint. For households seeking a comprehensive cleaning solution with minimal intervention, both models deliver automatic dust emptying, mop washing with hot water, and hot air drying—the hallmarks of a proper multifunctional base that genuinely improves mopping performance.

Suction Power and Brushing System
Both models deliver 18,500 Pa of suction—a figure that places them amongst the most powerful robot vacuums available in 2025. This level of suction proves particularly effective on carpets and for extracting embedded dirt from hard floor grouting.
The DuoDivide anti-tangle brush system features on both robots. This design channels hair towards the central suction opening rather than wrapping it around the brush roller—a practical advantage for homes with long hair or pets. The side brushes on both models extend to reach into corners and along edges, and both include anti-tangle technology to minimise hair wrap.
Where the Qrevo Curv distinguishes itself is in its ability to lift the main brush during mopping. This prevents the brush from interfering with the mopping process and avoids spreading dry debris whilst the mops are working. The Edge S5A lacks this feature, meaning the brush remains in contact with the floor during mopping operations. In practice, this makes the Curv slightly more refined when switching between vacuuming and mopping modes.
Mopping Performance
Both robots employ dual rotating mops that extend to reach edges and skirting boards—a design that improves coverage compared to fixed-width mop plates. The mops wash automatically in the base using hot water, which helps dissolve grease and dried-on marks more effectively than cold water alone. After cleaning, hot air drying prevents odours and bacterial growth.
The Qrevo Curv offers greater mop lift capability, raising the pads between 10-20 mm when moving over carpets or returning to the base. The Edge S5A lifts its mops 10 mm. For homes with thick rugs or higher carpet pile, the Curv's additional lift clearance reduces the risk of damp mops touching carpet fibres.
Both models detect dirt on the mops themselves and on the floor surface, triggering additional cleaning passes or mop washes as needed. Neither robot automatically removes its mops at the base for vacuum-only sessions—you'll need to detach them manually if you want pure vacuuming without mopping. Neither includes a detergent dispenser, so both rely on hot water alone for mop cleaning.
Navigation and Intelligence
This is where the most substantial differences emerge. The Qrevo Curv incorporates dual AI cameras alongside 3D laser sensors and LiDAR navigation. This combination allows it to recognise 62 different types of obstacles—from cables and slippers to pet waste and small toys. Pet recognition is specifically mentioned, meaning the robot can identify and avoid animals resting on the floor.
The Edge S5A uses LiDAR navigation with obstacle avoidance but lacks the camera-based AI system. Whilst it will still navigate methodically and avoid collisions, it cannot visually identify what objects are, nor can it distinguish between a shoe and a pet bowl. For households with cluttered floors or curious pets, the Curv's visual intelligence offers tangible benefits.
Remote camera access is available on the Qrevo Curv, allowing you to view live footage through the app—a feature some users appreciate for checking on pets or simply seeing what the robot encounters. The LED night vision light ensures the camera functions in low-light conditions. The Edge S5A offers none of these camera-related features.
Both models run SmartPlan 2.0 on the RR Mason 11.0 processor, so the fundamental navigation logic and route planning remains consistent. The difference lies in environmental awareness and adaptability.
Battery and Autonomy
The Qrevo Curv houses a 6,400 mAh battery providing up to 240 minutes of runtime. The Edge S5A's 5,200 mAh battery delivers 180 minutes. For most homes under 150 square metres, the Edge S5A's autonomy proves sufficient. Larger properties, or homes where the robot needs to complete multiple rooms in a single session, benefit from the Curv's extended runtime.
In practical terms, the Curv can cover more ground before returning to recharge, reducing the total time needed to clean an entire home. This becomes especially relevant when mopping, as the robot makes multiple trips to the base to rinse its mops—each trip consumes battery.
Advanced Features
The Qrevo Curv's adaptive chassis system allows it to climb obstacles up to 30 mm high—useful for navigating raised door thresholds, thick carpet edges, or uneven floor transitions. The Edge S5A manages 20 mm, which still handles most standard thresholds but may struggle with particularly high obstacles.
A built-in voice assistant features on the Qrevo Curv, enabling direct voice commands without relying on external systems. The Edge S5A lacks this onboard assistant but still integrates with Alexa and Google Home for voice control through those platforms. For users who prefer speaking directly to the robot rather than through a smart speaker, the Curv offers that convenience.
Multifunctional Base
Both bases provide the same core functions: automatic dust emptying into a 2.5-litre bag (Curv) or 2.7-litre bag (Edge S5A), hot water mop washing, and hot air mop drying. The self-cleaning base tray feature—version 2.0 on both models—rinses the washing area to prevent residue build-up.
Water tank capacities are nearly identical: 4 litres of clean water on both, with 3 litres of dirty water capacity on the Curv and 3.5 litres on the Edge S5A. These volumes suit homes up to around 200 square metres without needing frequent refills.
Neither base includes UV disinfection, detergent dispensers, or automatic mop changing systems. Neither offers integrated plumbing connections or optional kits for permanent water supply—both require manual filling and emptying.
Physical Dimensions
The robots themselves measure 352 mm in diameter, but the Qrevo Curv stands 103 mm tall whilst the Edge S5A measures 98 mm. That 5 mm difference could determine whether the robot fits beneath certain furniture. For low-clearance sofas or bed frames, the Edge S5A's lower profile may prove decisive.
Base dimensions differ more dramatically. The Qrevo Curv's base forms a 450 mm cube—compact for a multifunctional station but requiring nearly half a metre of floor space in each direction. The Edge S5A's base is narrower at 340 mm wide but taller at 521 mm and deeper at 487 mm. This vertical design suits narrower spaces but needs more vertical clearance—important if you're placing it under shelving or in a cupboard.
Real-World Usage Considerations
For larger homes exceeding 150 square metres, the Qrevo Curv's extended battery life and superior obstacle recognition make daily cleaning more reliable. The ability to identify pets means less risk of unfortunate encounters, whilst the enhanced mop lift and brush lifting create a more refined cleaning process.
Households with pets will appreciate the Curv's visual recognition and 62-obstacle database. The remote camera access also allows checking on animals whilst away. The Edge S5A performs the core cleaning tasks equally well but lacks these monitoring and recognition features.
If your home features very low furniture—perhaps a modern platform bed or minimalist sofa—the Edge S5A's 98 mm height grants access where the Curv's 103 mm frame might not fit. This seemingly small difference matters when furniture clearance sits right at that threshold.
For homes with challenging floor transitions, thick carpet borders, or raised doorways, the Curv's 30 mm obstacle climbing capability versus the Edge S5A's 20 mm could mean the difference between seamless room-to-room movement and getting stuck.
Both robots handle hard floors, tiles, and carpets effectively thanks to their 18,500 Pa suction and dual rotating mops. The hot water mop washing and hot air drying on both bases ensure genuinely clean mopping rather than just pushing dirty water around—a critical feature that separates these from mid-range models.
Conclusion: Which to Choose?
Choose the Roborock Qrevo Curv if: you want the most advanced navigation intelligence with dual AI cameras and 62-obstacle recognition; you have pets and value visual identification and remote camera monitoring; your home is large (over 150 m²) and benefits from the 240-minute battery life; you need to climb obstacles up to 30 mm; you prefer the refinement of automatic brush lifting during mopping; or you want the built-in voice assistant for direct commands.
Choose the Roborock Qrevo Edge S5A if: you have furniture with very low clearance (under 100 mm) where the 98 mm height proves essential; your home is under 150 m² where the 180-minute battery suffices; you prefer a narrower base footprint (340 mm versus 450 mm) to fit tighter spaces; you don't require camera-based obstacle identification or pet recognition; or you want to save money without sacrificing core cleaning performance—both models share the same suction power, brush system, and multifunctional base capabilities.
In this comparison between two premium Roborock models from 2024, the choice ultimately depends on whether you value advanced AI features and extended autonomy (Qrevo Curv) or prioritise a lower robot profile and narrower base (Qrevo Edge S5A). Both deliver excellent cleaning results with proper multifunctional bases—the decision rests on which specific features align with your home layout and preferences.
