Introduction
The Roborock Qrevo Curv 2 Flow and Roborock Qrevo Edge S5A represent two distinct approaches within Roborock's premium robot vacuum range. The Qrevo Curv 2 Flow arrives in February 2026 with a focus on advanced AI capabilities and a unique roller mopping system, whilst the Qrevo Edge S5A from 2024 offers proven performance with dual rotating mops and an extendable side brush for edge cleaning. Both models feature multifunctional bases that handle automatic emptying, mop washing with hot water, and hot air drying—essential components for maintaining genuinely clean floors without constant manual intervention.
These are high-end solutions designed for users who want comprehensive automation. The differences between them reveal two philosophies: one prioritising cutting-edge intelligence and camera-based navigation, the other delivering solid performance through mechanical precision and proven navigation algorithms.
Suction and Brushing Performance
The Qrevo Curv 2 Flow delivers 20,000 Pa of suction power, providing a noticeable advantage over the Edge S5A's 18,500 Pa. In practice, this translates to better extraction of embedded dirt from carpets and more effective pickup of fine dust from hard floors. Both models use Roborock's DuoDivide anti-tangle main brush, which channels hair towards the central suction inlet rather than wrapping it around the roller—a genuine benefit for homes with long-haired occupants or pets.
What sets the Curv 2 Flow apart is its ability to lift the main brush during mopping. This prevents damp debris from being spread across floors and keeps the brush cleaner. The side brush also lifts on this model, reducing interference with the mopping process. The Edge S5A lacks both these lifting mechanisms, though it compensates with an extendable side brush that reaches into corners more effectively. Both models feature anti-tangle side brushes, with the Curv 2 Flow using a dual-brush configuration.
Mopping Systems
Here lies one of the most fundamental distinctions. The Qrevo Curv 2 Flow employs a 270 mm roller mop that spins continuously as the robot moves, scrubbing floors with consistent pressure. The Qrevo Edge S5A uses dual rotating mops that press downward and spin independently. Roller systems tend to maintain more even contact with uneven surfaces, whilst dual mops can apply concentrated pressure to stubborn marks.
Both models extend their mops to reach edges and corners. The Curv 2 Flow lifts its mop 15 mm and includes a dedicated carpet mode for deeper pile, whereas the Edge S5A offers 10 mm elevation. For homes with varied flooring—perhaps rugs in living areas and tiles in kitchens—the extra lift height matters. Both robots detect dirty mops and re-clean them at the base, and both identify soiled areas on floors to trigger additional passes.
Mop washing happens with hot water in both bases, improving the breakdown of grease and grime. Hot air drying follows, preventing odours and bacterial growth. The Curv 2 Flow's base features standard self-cleaning of the wash tray, whilst the Edge S5A uses version 2.0 of this system, suggesting refinements in drainage or brush design. Neither model can automatically detach mops when switching to vacuum-only mode, nor do they include detergent dispensers.
Navigation and Intelligence
Both robots navigate using 3D LiDAR housed in a turret, mapping rooms accurately and planning efficient cleaning routes. The Qrevo Edge S5A runs RR Mason 11.0 algorithms with SmartPlan 2.0 intelligence, providing reliable obstacle avoidance and systematic coverage.
The Qrevo Curv 2 Flow takes navigation several steps further. It incorporates an AI camera, a front-facing 3D laser sensor, and LED lighting for visibility in dark spaces. This combination allows it to recognise 200 different obstacle types, including pets, and adjust behaviour accordingly. Remote camera access lets you check on your home through the robot's lens—useful for monitoring pets or simply verifying cleaning progress. SmartPlan 3.0 brings enhanced route optimisation and AI-based stain recognition, directing the robot to focus on visibly dirty patches.
For households with multiple obstacles—toys scattered about, charging cables, pet bowls—the Curv 2 Flow's advanced sensing reduces the need for pre-cleaning tidying. The Edge S5A handles obstacles competently but relies solely on LiDAR and basic sensors, making it less adaptable to cluttered environments.
Battery and Runtime
Both models carry 5,200 mAh batteries, yet the Qrevo Curv 2 Flow achieves 242 minutes of runtime compared to the Edge S5A's 180 minutes. This 62-minute difference likely stems from more efficient power management or optimised motor control in the newer model. For larger properties—perhaps over 150 square metres—the extended autonomy reduces the likelihood of mid-clean recharging interruptions.
Smart Features
Both robots climb obstacles up to 20 mm high, managing thresholds and low transitions between rooms without assistance. Neither includes a robotic arm for manipulating objects.
The Qrevo Curv 2 Flow integrates its own voice assistant, enabling direct interaction without relying on external smart home ecosystems. The Edge S5A supports Alexa and Google Home but lacks onboard voice control. Both models connect to these external assistants, so the difference matters mainly if you prefer standalone operation or have privacy concerns about cloud-based voice services.
Multifunctional Base
Both bases handle auto-emptying into 2.7-litre dust bags, mop washing with hot water, and hot air drying. Water tanks hold 4 litres of clean water and 3.5 litres of dirty water—sufficient for multiple cleaning sessions in medium-sized homes before refilling becomes necessary. Neither base offers UV disinfection, detergent dispensing, or plumbed water connections, though no optional plumbing kit exists for either model.
The self-cleaning wash tray on both bases reduces maintenance, though the Edge S5A's 2.0 version may offer improved reliability or easier access for manual cleaning when needed.
Dimensions
The Qrevo Edge S5A measures 98 mm tall, allowing it to slip beneath low furniture like sofas, beds, and cabinets with minimal clearance. The Qrevo Curv 2 Flow stands 119 mm high—21 mm taller—which may prevent access under particularly low pieces. Both have similar diameters (353 mm versus 352 mm), so turning radius and manoeuvrability remain comparable.
Base dimensions differ considerably. The Curv 2 Flow's base forms a 450 mm cube, occupying more floor space but presenting a symmetrical footprint. The Edge S5A's base measures 340 mm wide, 521 mm tall, and 487 mm deep—a more vertical profile that may fit better against walls or in narrower alcoves. Consider your available floor space when choosing between these configurations.
Real-World Use
For larger homes, the Qrevo Curv 2 Flow's extended runtime and higher suction make it better suited to covering extensive floor areas without recharging. The roller mop excels on hard floors with moderate soiling, maintaining consistent scrubbing pressure across uneven tiles or worn wooden boards.
Pet owners benefit from the anti-tangle brushes on both models, but the Curv 2 Flow's AI recognition of pets means it can navigate around resting animals without bumping them or getting tangled in bedding. The camera and remote access also let you check on pets whilst away.
Homes with low furniture favour the Edge S5A's slimmer profile. If your sofa sits 100-110 mm off the floor, the Edge S5A cleans beneath it; the Curv 2 Flow cannot. The extendable side brush on the Edge S5A also improves corner coverage, which matters in rooms with many recesses or furniture legs.
For mixed flooring—hard surfaces interspersed with rugs—the Curv 2 Flow's 15 mm mop lift and carpet mode handle transitions more gracefully. The Edge S5A's 10 mm lift suffices for low-pile rugs but may struggle with thicker mats.
Cluttered environments benefit from the Curv 2 Flow's advanced obstacle detection. If you have children who leave toys scattered, or multiple rooms with varied furniture layouts, the AI camera and 3D sensor reduce the need to tidy before each cleaning session.
Conclusion: Which to Choose?
