Roborock Qrevo Curv S5X vs Roborock Qrevo Edge 2 Flow

Introduction

The Roborock Qrevo Curv S5X and the Roborock Qrevo Edge 2 Flow represent two different generations within Roborock’s premium range. The former arrived in 2024 as a robust model with a complete multifunctional dock, while the Edge 2 Flow, launched in August 2026, introduces significant improvements in artificial intelligence and cleaning capability. Both are designed for homes seeking fully automated vacuuming and mopping, with anti-tangle systems and docks that wash the mops with hot water.

The generational difference is particularly noticeable in suction power and navigation. The Roborock Qrevo Edge 2 Flow offers almost twice the power and adds advanced visual recognition, which may make a significant difference in homes with pets or numerous obstacles.

Suction power and vacuuming

Suction power is one of the clearest differences between these two Roborock robot vacuums. The Qrevo Curv S5X delivers 18,500 Pa, a respectable figure for most homes. However, the Qrevo Edge 2 Flow almost doubles this with 35,000 Pa, providing more effective removal of embedded dirt from carpets and better cleaning of gaps in hard floors.

Both models use the DuoDivide anti-tangle brush, specifically designed to direct hair and pet fur towards the central suction inlet. This system significantly reduces tangles, which is particularly helpful in homes with long hair or pets. Both robots also feature an anti-tangle side brush.

The Edge 2 Flow stands out by lifting both its main and side brushes while mopping. This prevents the brushes from becoming unnecessarily wet and allows cleaner mopping without dragging dust across the floor. The Curv S5X does not lift either brush, although it compensates with an extendable side brush that improves corner cleaning. The Edge 2 Flow uses a reversible side brush as a different approach to reaching corners.

Mopping

The mopping system is another area in which these two Roborock robot vacuums differ significantly. The Qrevo Curv S5X uses two rotating mop pads spinning at 200 RPM, a proven and effective design for moderate stains. The Qrevo Edge 2 Flow changes approach with a 270 mm roller spinning at 240 RPM, covering more surface area with each pass and providing more even mopping.

Mop lifting is also improved on the Roborock Qrevo Edge 2 Flow. The Curv S5X can lift its mop pads by up to 10 mm, which is sufficient to cross thin carpets without wetting them. The Edge 2 Flow reaches 15 mm and also covers the roller, helping ensure that carpets remain completely dry. This is particularly useful in homes with rugs and carpets spread across several rooms.

Both robots extend their mopping components to reach edges and skirting boards more effectively. They also detect dirt on both the mops and the floor, adjusting the cleaning accordingly. In practice, this means they can automatically mop particularly dirty areas again without manual intervention.

Navigation system

The Roborock Qrevo Curv S5X navigates using a 360-degree LiDAR turret that maps the home accurately. It is a reliable system that works well even in low-light conditions. The Qrevo Edge 2 Flow uses retractable LiDAR that lowers when it is not needed, reducing the robot’s total height to 89.8 mm and making it easier to clean beneath low furniture.

The major difference lies in artificial intelligence. The Edge 2 Flow incorporates an RGB camera, a front-facing 3D laser sensor with structured light and an LED for night vision. It recognises up to 280 types of obstacles, identifies pets and can clean behind curtains without becoming tangled. The Curv S5X has no camera, so its recognition capabilities are more limited.

Remote access to the Edge 2 Flow’s camera makes it possible to monitor the home through the app, an additional security feature not offered by the Curv S5X. SmartPlan 3.0 on the Edge 2 Flow includes AI stain recognition and automatically adjusts cleaning according to the type of dirt detected. The Curv S5X uses SmartPlan 2.0, which is also intelligent but lacks this specific ability to identify stains visually.

Runtime and battery

Both robots use 5,200 mAh batteries. The Qrevo Curv S5X has a stated runtime of 180 minutes, which is more than sufficient for medium-to-large homes on a single charge. The Edge 2 Flow does not specify its runtime in minutes, although its identical battery capacity suggests potentially similar performance.

One advantage of the Curv S5X is fast charging, which reduces waiting times between cleaning sessions. The Edge 2 Flow does not include this feature, potentially resulting in longer charging times if its battery runs out during an intensive cleaning cycle.

Smart features

Both robots can cross obstacles up to 20 mm high, allowing them to negotiate thick cables, deep-pile carpets and small changes in floor level without becoming stuck. This capability is identical on both models.

The Roborock Qrevo Edge 2 Flow adds its own integrated voice assistant, allowing users to issue commands directly without using the app or external assistants. The Curv S5X does not have this feature, although both models are compatible with Alexa, Google Home and Matter.

Multifunctional cleaning dock

Both multifunctional docks share the essential features: automatic dustbin emptying, mop washing with hot water at 75°C and warm-air drying. Their water tank capacities are virtually identical, with 4 litres for clean water and 3 litres for dirty water.

Mop drying is more intensive on the Edge 2 Flow, using hot air at 63°C compared with 45°C on the Curv S5X. Higher temperatures speed up drying and reduce the risk of unpleasant odours. The Edge 2 Flow’s dust bag is slightly larger at 2.7 litres compared with 2.5 litres, although both should provide several weeks of use before replacement.

The Curv S5X includes the 2.0 self-cleaning wash tray, while the Edge 2 Flow uses a removable tray for manual cleaning. This is largely a matter of preference: self-cleaning is more convenient, while a removable tray allows for more thorough cleaning when required.

Dimensions

The diameter is virtually identical: 352 mm for the Curv S5X and 353 mm for the Edge 2 Flow. The key difference is height. The Edge 2 Flow measures 89.8 mm, allowing it to fit beneath furniture, beds and sofas with around 9 cm of clearance. The Curv S5X, at 98 mm, requires slightly more room.

The docks also differ slightly. The Curv S5X dock has a squarer shape and measures 450 × 450 × 450 mm, while the Edge 2 Flow dock is narrower but deeper at 402 × 451 × 470 mm. Neither occupies excessive space, but it is worth measuring the available area if space is limited.

Real-world use

In large homes, the Qrevo Edge 2 Flow’s greater power may make a noticeable difference. Its 35,000 Pa enables deeper cleaning with fewer passes, particularly on carpets or where dirt has accumulated. The 270 mm mopping roller also covers more surface area, reducing the total cleaning time.

For homes with pets, the Edge 2 Flow offers clear advantages: it recognises animals, avoids disturbing them and allows owners to monitor them through the camera when away from home. The DuoDivide brush works well on both models, but the Edge 2 Flow’s additional power helps extract more deeply embedded pet hair.

If the home has plenty of low furniture, the Edge 2 Flow’s reduced 89.8 mm profile is a decisive advantage. It can clean beneath beds and sofas that the Curv S5X cannot access. The improved lifting of its mopping system and brushes also makes transitions between hard floors and carpets easier without manual intervention.

The Curv S5X retains the advantage of fast charging and offers a solid navigation system, albeit without a camera. For homes without pets and with few complex obstacles, SmartPlan 2.0 and its 18,500 Pa may be more than sufficient.

Conclusion: which should you choose?

Choose the Roborock Qrevo Curv S5X if you want a reliable 2024 Roborock robot vacuum with a complete multifunctional dock, fast charging and a potentially more affordable price.
