Introduction
Two high-end models from Roborock that represent the technological evolution of the leading brand in the sector. The Qrevo CurvX arrived in 2025 as one of the most advanced units in its catalogue, whilst the Qrevo Edge 2 was introduced in May 2026 incorporating improvements in several key areas. Both are designed for homes seeking completely autonomous cleaning, with advanced navigation systems, multifunctional bases and rotary mopping capabilities.
We're talking about robots designed for large homes where total autonomy and minimal maintenance are valued. The generational difference between them translates into technical refinements that are worth analysing to understand which model best suits each need.
Power and Suction
Suction power is one of the first aspects where the evolution between generations is evident. The Qrevo Edge 2 develops 25,000 Pa, a figure that exceeds the CurvX by 3,000 Pa. In practice, this translates into greater capacity to extract ingrained dirt from carpets or tile joints, especially useful in homes with pets where hair tends to adhere strongly.
Both feature Roborock's DuoDivide Anti-Tangle system, which pushes hairs towards the central gap for direct suction. This design drastically reduces tangles that require manual brush cleaning every few days. Both models raise the main brush during mopping to prevent it getting wet and losing effectiveness.
The extendable side brush is present on both, allowing better corner sweeping by projecting outwards. They also share anti-tangle technology on this element and extension capability, although neither raises the side brush during mopping. For homes with long-haired animals, this brush configuration makes a notable difference in weekly maintenance.
Mopping
Both robots use dual rotating mops that extend to reach edges. Mop lifting presents differences: the CurvX can raise them between 7 and 17 mm depending on the surface, whilst the Edge 2 offers a fixed 12 mm lift. This capability allows both models to traverse carpets without wetting them during mopping sessions.
Water temperature marks an important distinction. The Qrevo CurvX mops with cold water, whilst the Edge 2 incorporates warm water. Mopping with warm water better dissolves grease and adhered stains, especially in kitchens or high-traffic areas. This improvement is noticeable in the effectiveness of washing the mops themselves at the base.
Only the Qrevo Edge 2 can automatically detach the mops at the base. This means that if you schedule a vacuum-only cleaning session, the robot leaves the mops at the station and works without dragging them across the floor. The CurvX keeps the mops raised but attached, which may result in minimal contact in some cases.
Both detect dirt on both the mops and the floor. When the system identifies that the mops are very dirty or detects a stain on the floor, it activates additional washing or scrubbing cycles. This adaptive intelligence reduces the need for manual touch-ups.
Navigation System
Retractable LIDAR equips both models, allowing them to map precisely and pass under low furniture when the sensor retracts. The AI camera is present on both, although the CurvX features a dual configuration compared to the Edge 2's single camera. However, the Edge 2 compensates with a qualitative leap in recognition: it identifies up to 280 different types of obstacles, compared to the CurvX's 108.
This expanded recognition capability includes curtain detection, a function the CurvX doesn't incorporate. For homes with long curtains that touch the floor, this prevents the robot from attempting to pass underneath or getting tangled. The Edge 2 also adds AI stain recognition, allowing automatic adjustment of mopping intensity in specific areas.
Both recognise pets, feature a front 3D laser sensor to avoid floor-level obstacles and offer night vision LED along with remote camera access. The SmartPlan system evolves from version 2.0 on the CurvX to 3.0 on the Edge 2, optimising routes and adapting cleaning according to the detected room type.
Autonomy and Battery
Here the Qrevo CurvX takes the advantage with its 6,400 mAh battery providing 220 minutes of autonomy. The Qrevo Edge 2 features 5,200 mAh for 188 minutes of continuous operation. The difference of more than half an hour can be decisive in large homes where the robot needs to complete the entire surface without returning to charge mid-session.
In practice, 220 minutes allow cleaning approximately 300-350 square metres in mixed vacuum and mop mode, whilst the Edge 2's 188 minutes comfortably cover between 250 and 300 square metres. For flats under 200 square metres, both complete cleaning without problems. The CurvX's larger battery adds a safety margin in multi-storey houses or complex layouts.
Smart Features
The ability to overcome obstacles differs between models. The CurvX can cross simple steps without specifying exact height, whilst the Edge 2 overcomes up to 20 mm. This allows the Edge 2 to transit between rooms with small level changes, flooring transitions with aluminium profiles or thick carpets without getting stuck.
Both incorporate their own voice assistant in addition to compatibility with Alexa and Google Home. This makes it easy to give direct commands without needing to open the app, particularly practical for initiating spot cleaning or sending the robot to a specific room using voice commands.
Multifunctional Cleaning Base
Both bases auto-empty the dust bin, wash the mops with hot water and dry them with hot air. Hot water washing at the base improves mop hygiene between sessions, better eliminating organic residue and grease. Hot air drying accelerates the process and prevents bad odours.
The wash tray self-cleaning presents different versions: 3.0 on the CurvX versus 2.0 on the Edge 2. Although both systems keep the tray where the mops are washed clean, the CurvX's 3.0 version incorporates improvements in the rinse and drainage cycle that reduce residue accumulation in the long term.
The dust bag reaches 2.5 litres on the CurvX and 2.7 litres on the Edge 2. The clean water tank is identical on both at 4 litres, whilst the dirty water tank varies: 3 litres on the CurvX and 3.5 litres on the Edge 2. These capacities allow several weeks of use before emptying the bag or refilling tanks, depending on surface area and cleaning frequency.
Neither includes a detergent tank, UV disinfection nor integrated plumbing connection or optional kit. Mop cleaning is performed exclusively with hot water.
Dimensions
The robots present practically identical measurements: 353 mm diameter on the CurvX versus 352 mm on the Edge 2, with a common height of 79.8 mm. This reduced height allows passage under most sofas and low furniture, also taking advantage of the retractable LIDAR which further decreases the profile when necessary.
The bases differ notably in configuration. The CurvX occupies a 450x450x450 mm cube, a compact and symmetrical format that facilitates placement in corners. The Edge 2 measures 340 mm wide, 521 mm high and 487 mm deep, being narrower but also taller. It's advisable to measure available space before deciding, especially if the base will go under furniture or in a cleaning cupboard.
Real-World Usage Experience
For large homes, the CurvX's greater autonomy offers peace of mind by completing large surfaces without interruptions. The Edge 2 compensates with greater suction power and ability to overcome obstacles up to 20 mm, an advantage in houses with level changes or thick carpets.
In homes with pets, both feature the DuoDivide brush that minimises tangles, but the Edge 2 adds an extra 3,000 Pa of suction that better extracts embedded hair. The Edge 2's expanded obstacle detection also avoids problems with pet toys or feeding bowls.
The Edge 2's warm water mopping makes a difference in kitchens or areas with grease stains. The ability to automatically detach the mops allows vacuum sessions without dragging the pads, useful when you only need to sweep without mopping. The CurvX maintains a more advanced tray self-cleaning system, reducing manual maintenance in the long term.
The CurvX's base is more compact in footprint but cubic, whilst the Edge 2's is narrower although it protrudes in height. Depending on available space, one configuration may fit better than the other.
Conclusion: Which to Choose?
Choose the Roborock Qrevo CurvX if you live in a large house where the 220-minute autonomy is necessary to complete the entire surface in a single session. Also if you value the 3.0 tray self-cleaning system that reduces long-term maintenance, or if you have space for a cubic-format base. The dual AI camera and consolidated design make it a reliable option for those seeking a proven and effective robot.
Choose the Roborock Qrevo Edge 2 if you need the maximum available suction power with its 25,000 Pa, especially useful in homes with pets or carpets. Warm water mopping improves effectiveness against adhered stains, and the ability to automatically detach mops adds versatility. Its expanded recognition of 280 obstacles, AI curtain and stain detection, together with the ability to overcome 20 mm in height, position it as the most technologically advanced model. Ideal for homes with complex layouts, level changes or long curtains where intelligent navigation makes the difference. The narrower base facilitates integration in reduced spaces.
