Introduction
The three models we're going to analyse belong to Roborock's Qrevo family, one of the most comprehensive ranges from the Chinese manufacturer. The Roborock Qrevo Curv S5X and the Roborock Qrevo Edge S5A arrived on the market during 2024, whilst the Roborock Qrevo S5V is the most recent model, introduced in 2025. All of them integrate a multifunction base with auto-empty, mop washing and drying, which places them in the premium segment.
Although they share a general architecture and many technical specifications, there are important differences in suction power, base tank capacity and smart functions that are worth knowing before making a decision. These units are designed for users seeking total autonomy and effective mopping with hardly any manual intervention.
Power and Suction
Suction power marks a notable difference in this robot vacuum comparison. The Roborock Qrevo Curv S5X and the Roborock Qrevo Edge S5A deliver 18,500 Pa, an excellent figure that guarantees reliable results on carpets and floors with ingrained dirt. The Roborock Qrevo S5V, despite being the most recent model, offers 12,000 Pa. It's still a respectable power for regular domestic use, but the difference may be noticeable in homes with pets or medium-pile carpets.
All three units feature the DuoDivide Antienredos system, Roborock's exclusive design that pushes hair and strands towards the central gap to facilitate suction. This brush considerably reduces tangles and simplifies maintenance.
Regarding the side brush, the Roborock Qrevo Curv S5X and the Roborock Qrevo Edge S5A incorporate side extension to improve cleaning in corners and edges. The Roborock Qrevo S5V does without this function. All three models have an anti-tangle side brush, but none lifts the brush during mopping nor the main brush when the mop is activated.
Mopping
The mopping system is identical in architecture: two rotating mops with extension capability to better reach edges and skirting boards. All three models lift the mops up to 10 mm when they detect carpets or rugs, a sufficient height to avoid wetting them in most situations. All use cold water both for mopping the floor and for washing the mops at the base.
The most relevant difference appears in dirt detection. The Roborock Qrevo Curv S5X and the Roborock Qrevo Edge S5A analyse the level of dirt on the mops and on the floor, adjusting the scrubbing when necessary. This smart function improves mopping effectiveness without user intervention. The Roborock Qrevo S5V lacks this capability, so it performs more uniform mopping without adapting to particularly dirty areas.
None of the three models automatically removes the mops at the base to perform vacuum-only sessions, something that some premium competitors do offer.
Navigation System
All three Roborock robot vacuums use LiDAR turret with obstacle avoidance. All integrate the SmartPlan AI-powered intelligent cleaning system, which optimises routes and manages cleaning autonomously. The Roborock Qrevo Curv S5X and the Roborock Qrevo Edge S5A run on the RR Mason 11.0 processor, whilst the S5V does not specify this information in the available technical data.
None of the three models incorporates an AI front camera, front 3D laser sensor, specific pet or curtain recognition, nor remote camera access. They also don't feature night vision LED. Navigation is based exclusively on LiDAR and integrated obstacle avoidance sensors.
Autonomy and Battery
In this section there are no differences. All three units feature a 5,200 mAh battery that provides up to 180 minutes of autonomy. This capacity is more than sufficient for medium and large-sized homes, allowing cleaning sessions to be completed without the need for intermediate recharges on surfaces of up to approximately 200-250 m².
Smart Functions
The ability to overcome obstacles is identical: 20 mm in height. This allows crossing small level changes, transitions between rooms with metal profiles or thick carpets without getting stuck. It's a standard height in the current premium segment.
All three models are compatible with external voice assistants such as Alexa and Google Home, facilitating voice control. None integrates a robotic arm or its own voice assistant.
Multifunction Cleaning Base
Here we find some of the most important differences in this Roborock robot vacuum comparison. All three models feature a multifunction base that auto-empties the dust bin, washes the mops with hot water and dries them with hot air. This system ensures that the robot returns periodically during mopping to clean the mops, always maintaining an optimal level of hygiene.
The Roborock Qrevo Curv S5X and the Roborock Qrevo Edge S5A incorporate 2.0 self-cleaning of the washing tray, which notably reduces manual maintenance. The Roborock Qrevo S5V does not have this function, so the tray requires periodic cleaning by the user.
Regarding capacities, the Roborock Qrevo Curv S5X has a 2.5-litre dust bag and a 3-litre dirty water tank. The Roborock Qrevo Edge S5A and the Roborock Qrevo S5V offer a 2.7-litre dust bag and 3.5 litres of dirty water. All three share a 4-litre clean water tank. These differences can translate into a few more days of autonomy before emptying or refilling tanks in the Edge S5A and S5V models.
None includes UV disinfection, detergent tank, automatic mop changing or connection to water pipes.
Dimensions
The robot itself has practically identical dimensions. The Roborock Qrevo Curv S5X and the Roborock Qrevo Edge S5A measure 352 mm in diameter and 98 mm in height. The Roborock Qrevo S5V has 353 mm in diameter and 96.5 mm in height. Those 1.5 mm less can slightly facilitate access under low furniture or beds with little clearance.
The base presents more significant differences. The Roborock Qrevo Curv S5X has a square design of 450 mm in width, height and depth, which gives it a more compact and symmetrical appearance. The Roborock Qrevo Edge S5A and the Roborock Qrevo S5V share dimensions: 340 mm wide, 521 mm high and 487 mm deep. The Curv S5X base occupies more floor space but is less tall, whilst the Edge S5A and S5V bases are narrower but considerably taller.
Real-World Experience
For homes with pets, the greater suction power of the Roborock Qrevo Curv S5X and the Roborock Qrevo Edge S5A makes a difference. The 18,500 Pa guarantees better pickup of hair embedded in carpets and rugs. The extendable side brush on these two models also helps to better sweep corners where hair tends to accumulate.
The dirt detection on mops and floor of the Curv S5X and the Edge S5A is especially useful in kitchens or high-traffic areas, where the robot automatically insists on the dirtiest areas. The Roborock Qrevo S5V performs more uniform mopping, sufficient for regular maintenance but without that adaptive capability.
In large homes, all three offer similar autonomy, but the slightly larger tanks of the Edge S5A and the S5V reduce maintenance frequency. The 2.0 self-cleaning of the tray on the Curv S5X and the Edge S5A minimises manual interventions, something that's appreciated in day-to-day use.
The height difference of the S5V may be relevant if you have very low furniture or beds. Those 1.5 mm can make the difference between accessing certain areas or not.
Conclusion: Which One to Choose?
Choose the Roborock Qrevo Curv S5X if you're looking for maximum suction power, you have pets or demanding carpets, you value intelligent dirt detection and prefer a base with a more compact floor design. The square format of the base may fit better in certain spaces. The 2.0 self-cleaning of the tray reduces maintenance.
Choose the Roborock Qrevo Edge S5A if you want the best balance between power, smart functions and tank capacity. It offers the same 18,500 Pa and dirt detection as the Curv S5X, but with somewhat larger dirty water and dust bag tanks. The base is narrower, which facilitates its placement in confined spaces.
Choose the Roborock Qrevo S5V if you prioritise a tighter price and don't need maximum suction power or advanced dirt detection functions. It's the most recent model but with simplified features. The 12,000 Pa is sufficient for most homes without pets or thick carpets. The lower height can be an advantage for passing under very low furniture, although it lacks tray self-cleaning and extendable side brush.
In short, this Roborock robot vacuum comparison shows three solid options within the same family. The best robot vacuum 2025 of these three will depend on your priorities: maximum power and cleaning autonomy (Curv S5X or Edge S5A) or a more economical solution with adjusted features (S5V).
