Introduction
The Roborock Qrevo Curv and Roborock Qrevo Curv S5X represent two premium offerings from the world's leading robot vacuum manufacturer, both launched in 2024. These aren't entry-level devices—they're high-performance models equipped with multifunctional cleaning stations, rotating mops, and advanced navigation systems designed for households seeking comprehensive automation in both vacuuming and mopping tasks.
At first glance, these two models appear remarkably similar. They share the same powerful 18,500 Pa suction, identical DuoDivide anti-tangle brush systems, and comparable physical dimensions. The real question is whether the additional features found in the Qrevo Curv justify any potential price difference, particularly when it comes to navigation intelligence, battery capacity, and mechanical versatility.
For homeowners with pets, multi-floor properties, or those who value complete hands-off operation, understanding these distinctions becomes essential before making a purchasing decision.

Power and Suction
Both models deliver an impressive 18,500 Pa of suction power, placing them firmly in the premium category for 2025. This level of performance handles everything from fine dust on hard floors to embedded debris in medium-pile carpets without difficulty.
The DuoDivide anti-tangle brush system features on both robots. This design channels hair and fibres towards the central suction point rather than allowing them to wrap around the roller—a practical advantage for homes with long-haired occupants or shedding pets. The brush design works effectively with the side brush anti-tangle system, which also appears on both models.
Where they diverge is in brush management during mopping. The Qrevo Curv can elevate its main brush when mopping mode activates, preventing the roller from interfering with the wet cleaning process or picking up moisture. The S5X lacks this feature, meaning the main brush remains in contact with the floor throughout mopping operations.
Both units feature an extendable side brush that reaches into corners more effectively than fixed designs. This mechanism works identically across the two models, ensuring edge cleaning performance remains consistent regardless of which version you choose.
Mopping
The mopping systems are largely identical: dual rotating mops that extend to reach skirting boards and edges, hot water washing at the base station, and hot air drying to prevent odours and bacterial growth. The 2.0 self-cleaning tray system ensures the washing mechanism itself stays hygienic between cleaning cycles.
The critical difference lies in mop elevation. When the Qrevo Curv encounters carpets or rugs, it can lift its mops between 10-20 mm, providing greater clearance to avoid wetting textile floor coverings. The S5X manages 10 mm of lift, which suffices for most low-pile rugs but may prove insufficient for thicker carpets or raised door thresholds.
Both models detect dirt on the mops themselves and on the floor surface, triggering additional cleaning passes when necessary. This intelligent rewashing capability means stubborn marks receive extra attention without manual intervention. The mop extension function operates identically on both units, pushing one mop outward to clean right up to walls and furniture legs.
Neither robot automatically removes its mops at the base station for vacuum-only sessions, so you'll need to detach them manually if you want pure vacuuming without any mopping component. The base stations hold 4 litres of clean water and 3 litres of dirty water, with a 2.5-litre dust bag capacity—specifications that match across both models.
Navigation System
This is where the most substantial differences emerge. The Qrevo Curv employs a dual AI camera system combined with a 3D laser sensor at the front, enabling it to recognise 62 different obstacle types including pets, shoes, cables, and furniture. The S5X relies on its LiDAR turret for mapping and navigation but lacks the AI camera and 3D laser sensor entirely.
In practical terms, the Qrevo Curv can identify your cat sleeping in the hallway and navigate around it without contact, whilst the S5X would detect an obstacle but not understand what it is. The dual camera setup on the Qrevo Curv also enables remote viewing through the app, effectively turning the robot into a mobile security camera when you're away from home.
LED night vision on the Qrevo Curv allows the cameras to function effectively in low-light conditions, maintaining obstacle recognition accuracy even during evening cleaning sessions or in darker rooms. The S5X has no equivalent lighting system because it doesn't have cameras to illuminate.
Both models run the RR Mason 11.0 algorithm and SmartPlan 2.0 intelligent cleaning system, which optimises cleaning routes and adjusts settings based on room type and dirt levels. The underlying mapping and path planning intelligence remains consistent; it's the visual recognition capabilities that differ significantly.
Battery and Autonomy
The Qrevo Curv houses a 6,400 mAh battery delivering up to 240 minutes of runtime, whilst the S5X contains a 5,200 mAh cell providing 180 minutes. That's a full hour's difference in continuous operation—potentially decisive for larger properties or whole-home cleaning sessions.
In practice, this means the Qrevo Curv can cover more ground before returning to recharge, reducing interruptions during cleaning cycles. For homes exceeding 150 square metres, the extended autonomy translates to fewer mid-clean charging breaks and faster completion times.
Both robots return automatically to their base stations when battery levels drop, recharge as needed, and resume cleaning where they left off. The difference is simply how often this occurs during a full-home clean.
Intelligent Features
The Qrevo Curv can climb simple steps and obstacles, whilst the S5X handles obstacles up to 20 mm high. This adaptive climbing ability on the Qrevo Curv allows it to mount door thresholds, transition between rooms with level changes, and navigate uneven flooring more confidently.
Only the Qrevo Curv includes a built-in voice assistant, allowing direct interaction with the robot without needing to open the app or use a third-party smart speaker. Both models support external voice assistants like Alexa and Google Home, but the integrated assistant on the Qrevo Curv adds convenience for quick commands or status checks whilst you're nearby.
Multifunctional Cleaning Base
The base stations are functionally identical: automatic dust emptying into a 2.5-litre bag, hot water mop washing, hot air mop drying, and version 2.0 self-cleaning of the washing tray. Neither includes UV disinfection, detergent dispensers, or automatic mop changing systems.
The water tank capacities match at 4 litres clean and 3 litres dirty, providing sufficient reserves for multiple mopping sessions before manual refilling becomes necessary. Neither base offers plumbing connection capability, either integrated or via optional kit, so you'll be filling and emptying tanks manually regardless of which model you choose.
This maintenance requirement remains minimal—typically once every week or two depending on usage intensity and home size—but it's worth noting that neither model achieves true zero-intervention operation over extended periods.
Dimensions
The robots measure 352 mm in diameter, but height differs: 103 mm for the Qrevo Curv versus 98 mm for the S5X. That 5 mm difference might seem trivial, yet it determines whether the robot fits beneath certain furniture pieces. The S5X gains access under sofas, beds, and cabinets with 100 mm clearance, whilst the Qrevo Curv requires at least 105 mm.
For homes with low-profile furniture, this becomes a practical consideration. The S5X reaches areas the Qrevo Curv cannot, potentially reducing the amount of manual vacuuming required under beds and sofas.
The base stations share identical dimensions at 450 mm across all three measurements, forming a perfect cube. Both require the same floor space and fit in the same locations, so base station placement considerations remain constant between models.
Real-World Usage Experience
For larger homes exceeding 150 square metres, the Qrevo Curv's extended battery life and superior obstacle recognition deliver tangible benefits. The extra autonomy means fewer charging interruptions, whilst the AI cameras prevent the robot from getting stuck on cables, shoes, or pet toys that might halt a camera-less model.
Pet owners gain specific advantages from the Qrevo Curv's ability to recognise and avoid animals, reducing the risk of disturbing sleeping pets or encountering unexpected mess. The remote camera access also lets you check on pets whilst away, adding a secondary function beyond floor cleaning.
The S5X suits smaller properties or those with minimal floor clutter where obstacle recognition becomes less critical. Its lower profile provides better access under furniture, and the 180-minute battery capacity remains sufficient for homes up to 120-150 square metres. The absence of cameras means one less privacy consideration for households uncomfortable with camera-equipped devices.
Both models handle hard floors, tiles, and sealed wood effectively thanks to their rotating mops and hot water washing systems. The anti-tangle brush design benefits any household with hair concerns, whether from humans or pets. Carpet handling relies on that powerful 18,500 Pa suction, though the Qrevo Curv's greater mop lift provides better protection for thicker rugs.
Conclusion: Which Should You Choose?
Choose the Roborock Qrevo Curv if: You have a home exceeding 150 square metres and need extended battery life for uninterrupted whole-home cleaning. Pet owners benefit significantly from the animal recognition and remote camera monitoring. The superior obstacle avoidance suits homes with children where toys and clutter appear frequently on floors. If you have thicker carpets or multiple floor transitions, the enhanced mop lift and step-climbing ability prove worthwhile. The built-in voice assistant adds convenience if you prefer direct robot interaction without reaching for your phone.
Choose the Roborock Qrevo Curv S5X if: Your home measures under 120-150 square metres and the shorter battery life poses no practical limitation. The 5 mm height advantage matters if you have low-profile furniture requiring access underneath. Privacy-conscious households may prefer avoiding camera-equipped robots. If your floors remain relatively clear of obstacles and you don't have pets, the advanced AI recognition becomes less essential. The S5X delivers the same core cleaning performance—powerful suction, effective mopping, and hot water mop maintenance—at potentially lower cost.
Both represent excellent choices within the premium robot vacuum category for 2025. The decision ultimately depends on home size, furniture clearance requirements, pet ownership, and whether the advanced AI features justify any price premium for your specific circumstances.
