Introduction
Roborock presents three models within its successful Qrevo line that represent different approaches within the high-end range of robot vacuum cleaners. The Qrevo Curv 2 Flow arrived in 2026 as a proposal that prioritises autonomy and a mopping system with a rotating roller. The Qrevo Edge 2, also from 2026, opts for maximum suction power and an ultra-slim design with retractable laser navigation. The Qrevo Edge S5A, launched in 2024, positions itself as the most accessible alternative within this family, maintaining reliable performance whilst forgoing some advanced features.
All three units integrate a multifunctional base with mop washing and drying, which guarantees effective mopping in any case. However, the differences in power, navigation, design and intelligent capabilities mark quite distinct usage profiles.
Power and Suction
Suction power marks a notable difference between these three Roborock robot vacuum cleaners. The Qrevo Edge 2 leads with 25,000 Pa, a figure that places it amongst the most powerful on the market. The Curv 2 Flow reaches 20,000 Pa, whilst the Edge S5A remains at 18,500 Pa. In practice, these differences are particularly noticeable on medium or long pile carpets, where the capacity to extract embedded dirt improves with each power level.
All three models mount the DuoDivide Antienredos brush from Roborock, a design that pushes hair and strands towards the central gap to prevent tangles. This system proves especially useful in homes with pets or people with long hair. All incorporate a dual anti-tangle side brush, which reinforces cleaning on edges and corners without maintenance problems.
An interesting difference appears in brush elevation. The Curv 2 Flow and the Edge 2 raise the main brush during mopping, preventing it from getting wet and guaranteeing better hygiene. The Edge S5A lacks this function. Regarding the side brush, the Curv 2 Flow also raises it when mopping, whilst the Edge 2 and the Edge S5A opt to extend it to improve cleaning in corners. These are two different philosophies: one prioritises not dragging wet dirt, the other maximises coverage in difficult areas.
Mopping
The mopping system represents one of the most evident differences. The Qrevo Curv 2 Flow uses a 270 mm roller that rotates and mops continuously, similar to the operation of an electric mop. The Qrevo Edge 2 and Edge S5A employ two circular rotating mops that spin at high speed. Both systems work well, although the roller usually offers greater contact surface with each pass.
All three models extend the mops to better reach edges and detect dirt both on the mops and on the floor to insist where necessary. Mop elevation varies: the Curv 2 Flow reaches 15 mm and adds the AdaptLift system to overcome obstacles, the Edge 2 reaches 12 mm and the Edge S5A remains at 10 mm. These differences matter when passing over carpets or thresholds: the greater the elevation, the less risk of wetting textiles.
The Edge 2 incorporates warm water for mopping the floor, whilst the Curv 2 Flow and the Edge S5A use cold water. Warm water improves the dissolution of grease and adhered stains, especially in kitchens. Additionally, only the Edge 2 can automatically remove the mops at the base when you only want to vacuum, avoiding having to do it manually.
All three bases wash the mops with hot water at 60°C and dry them with hot air, which guarantees hygiene and absence of bad odours. Self-cleaning of the washing tray is present in all, although the Edge 2 and the Edge S5A incorporate version 2.0 of this system.
Navigation System
The Qrevo Edge 2 stands out for its retractable laser navigation, which allows reducing the total height of the robot to only 79.8 mm. This enables it to slip under furniture where the other two cannot enter. The Curv 2 Flow and the Edge S5A use conventional LiDAR turret, which explains their heights of 119 mm and 98 mm respectively.
Both the Curv 2 Flow and the Edge 2 integrate an AI camera, front 3D laser sensor, night vision LED and remote camera access. This allows monitoring the home from the app, identifying objects with precision and navigating even in low light. The Edge S5A forgoes all this visual technology, limiting itself to LiDAR for mapping and navigation.
Object recognition reaches 280 different types in the Edge 2, 200 in the Curv 2 Flow and is not specified in the Edge S5A. The Edge 2 adds specific curtain detection to avoid tangles, something the other two do not offer. All three recognise pets, except the Edge S5A which lacks this function as it does not have an AI camera.
All three models use SmartPlan to plan intelligent routes according to the type of floor and detected dirt. AI stain recognition is present in the Curv 2 Flow and the Edge 2, but not in the Edge S5A.
Autonomy and Battery
Battery capacity is identical in all three: 5,200 mAh. However, actual autonomy varies significantly. The Qrevo Curv 2 Flow reaches 242 minutes of continuous operation, the Edge 2 reaches 188 minutes and the Edge S5A remains at 180 minutes. These differences are due to the energy efficiency of each system: the mopping roller of the Curv 2 Flow appears to consume less than the dual rotating mops, and the greater power of the Edge 2 also influences energy consumption.
For large homes, that extra hour of autonomy from the Curv 2 Flow can make the difference between completing cleaning in a single pass or needing intermediate recharges.
Intelligent Features
All three Roborock robot vacuum cleaners overcome obstacles up to 20 mm in height, sufficient to pass standard thresholds and small rugs without problems. None incorporates a robotic arm.
The Curv 2 Flow and the Edge 2 include their own voice assistant integrated into the robot, in addition to compatibility with Alexa and Google Home. The Edge S5A only offers compatibility with external assistants, without its own voice. In practice, this means that the first two can respond directly to commands without the need for additional smart speakers.
Multifunctional Cleaning Base
All three bases share a similar structure: auto-emptying of the dust container with a 2.7-litre bag, mop washing with hot water at 60°C, drying with hot air and self-cleaning of the tray. The clean water (4 litres) and dirty water (3.5 litres) tanks are identical, sufficient for several mopping sessions without intervention.
None includes a detergent tank, UV disinfection or plumbing connection, features that do appear in other ultra-high-end models. Neither do they offer an optional plumbing connection kit. The difference lies in the tray self-cleaning version: the Curv 2 Flow mounts the first generation, whilst the Edge 2 and the Edge S5A incorporate version 2.0, presumably more efficient.
Dimensions
The diameter is practically identical: 353 mm in the Curv 2 Flow, 352 mm in the other two. Height marks important differences. The Edge 2, with only 79.8 mm, slips under sofas, beds and low furniture where the others cannot reach. The Edge S5A reaches 98 mm, a contained height but less versatile. The Curv 2 Flow, at 119 mm, is the tallest due to its conventional LiDAR turret and possibly the roller mopping system.
The bases of the Edge 2 and Edge S5A measure 340 mm wide, 521 mm high and 487 mm deep. The Curv 2 Flow base is more compact in height (450 mm) but more square (450 x 450 mm), occupying somewhat more floor space but less vertically. It is advisable to measure the available space before deciding, especially if you plan to place the base under furniture or in a tight corner.
Real-World Experience
The Qrevo Edge 2 stands out in homes with low furniture thanks to its reduced height. Its power of 25,000 Pa makes it the best option if you have thick carpets or pets that shed a lot of hair. Warm water for mopping and the ability to automatically remove mops add convenience in day-to-day use. Recognition of 280 objects and curtain detection make it especially reliable in homes with many obstacles or complex decoration.
The Curv 2 Flow shines in large homes where the autonomy of 242 minutes allows covering the entire surface without recharges. The roller mopping system offers a different experience, with greater contact surface with each pass. The elevation of side brushes during mopping avoids dragging wet dirt, something that is appreciated in kitchens or areas with frequent spills. Its greater height limits access under low furniture.
The Edge S5A represents the most balanced option for those seeking a Roborock robot vacuum cleaner with a multifunctional base without needing the latest technologies. It works well in medium-sized flats, with hard floors or thin carpets. The absence of an AI camera and advanced recognition functions does not affect basic cleaning, although it does limit the robot's ability to avoid small obstacles or cables. Its lower price makes it attractive if you do not need maximum power or extreme autonomy.
