Introduction
The Roborock Qrevo range represents some of the most sophisticated robot vacuum cleaners available in 2025, with three models that share the same DNA but target different user needs. The Qrevo CurvX stands as the flagship model launched in 2025, whilst the Qrevo Edge S5A arrived in 2024 as a premium mid-range option. The Qrevo S5V completes the lineup as the 2025 entry point into this advanced series.
All three incorporate Roborock's distinctive DuoDivide anti-tangle brush system and dual rotating mopas with edge extension capabilities. They're equipped with multifunctional bases that handle automatic emptying, mop washing with hot water, and hot air drying. What separates them are the navigation technologies, suction power levels, and intelligent features that determine which homes and cleaning challenges they're best suited for.
Suction and Cleaning Performance
The power hierarchy becomes immediately apparent when examining suction capabilities. The Qrevo CurvX delivers 22,000 Pa, making it exceptionally capable for deep carpet cleaning and extracting embedded debris. The Edge S5A sits at 18,500 Pa, still robust enough for most household challenges. The S5V operates at 12,000 Pa, which remains adequate for hard floors and low-pile carpets but won't match the others when tackling demanding tasks.
All three models employ Roborock's DuoDivide anti-tangle main brush, which channels hair towards the central suction opening rather than wrapping it around the roller. This design proves particularly valuable in homes with long-haired residents or pets. The CurvX goes further with an elevating main brush that lifts during mopping, preventing wet carpets and ensuring the brush doesn't interfere with the mopping action on hard floors.
For edge cleaning, the CurvX and Edge S5A feature extensible side brushes that reach deeper into corners. The S5V lacks this refinement, using a standard side brush configuration. All three incorporate anti-tangle technology in their side brushes, reducing maintenance frequency.
Mopping System
The mopping architecture remains consistent across all three: dual rotating mopas that extend to reach skirting boards and edges. Each model lifts its mopas when encountering carpets—10 mm on the Edge S5A and S5V, whilst the CurvX offers variable lift between 7 and 17 mm depending on carpet pile height. This adaptive approach means the CurvX can handle a wider range of floor transitions without manual intervention.
Dirt detection technology separates the premium models from the entry option. The CurvX and Edge S5A monitor both mop cleanliness and floor soiling, automatically returning to problematic areas for additional passes or washing their mopas when contamination reaches certain thresholds. The S5V cleans methodically but without this intelligent reassessment capability, which can mean the difference between acceptable and exceptional floor cleanliness in kitchens or high-traffic areas.
All three wash their mopas with hot water and dry them using heated air, preventing odour development and bacterial growth. None offers automatic mop removal for vacuum-only sessions, so you'll need to detach them manually if you're only tackling carpeted areas.
Navigation Technology
This is where the models diverge most dramatically. The Qrevo CurvX employs a retractable LiDAR system that lowers when not needed, contributing to its remarkably low 79.8 mm profile. It combines this with dual AI cameras and a 3D laser sensor that creates extraordinarily detailed environmental maps. The system recognises 108 different obstacle types, including specific pet detection that can identify animals and adjust cleaning patterns accordingly.
The Edge S5A and S5V use conventional LiDAR turrets, which explains their taller profiles. They navigate accurately but lack the advanced visual intelligence of the CurvX. The Edge S5A runs RR Mason 11.0 processing, matching the CurvX's computational platform, whilst the S5V's processor remains unspecified in available data.
Only the CurvX provides remote camera access, allowing you to check on your home through the robot's cameras when you're away. It also incorporates LED illumination for night vision, useful for evening cleaning sessions or monitoring dark spaces. These features simply don't exist on the Edge S5A or S5V.
Battery and Range
The CurvX carries a 6,400 mAh battery delivering 220 minutes of runtime—enough for extensive properties without mid-clean recharging. The Edge S5A and S5V share 5,200 mAh cells providing 180 minutes each. In practical terms, the CurvX can cover larger floor areas in a single session, whilst the other models may need to dock and resume when tackling sprawling homes.
The additional capacity becomes particularly valuable when combining vacuuming with mopping, as the latter consumes more power due to mop rotation and frequent base returns for washing. For properties exceeding 150 square metres, the CurvX's extended autonomy translates to faster completion times.
Intelligent Features
All three models manage 20 mm obstacles, though the CurvX specifies this as single-step capability, suggesting more sophisticated climbing algorithms. This height allows them to mount standard door thresholds and cross between rooms with different flooring levels.
The CurvX includes an onboard voice assistant, enabling direct communication without relying on external smart speakers. All three integrate with Alexa and Google Home for those preferring established ecosystems. The SmartPlan AI feature appears on both the CurvX and Edge S5A, optimising cleaning schedules based on room usage patterns and historical dirt accumulation data.
Multifunctional Base Station
Each model empties its dust container automatically and handles mop washing with hot water followed by hot air drying. The distinction lies in base self-maintenance. The CurvX features version 3.0 of Roborock's self-cleaning tray system, the Edge S5A uses version 2.0, and the S5V requires manual tray cleaning. Over weeks of operation, this difference becomes noticeable in terms of maintenance demands.
Dust bag capacity varies slightly: 2.5 litres in the CurvX versus 2.7 litres in the Edge S5A and S5V. Clean water tanks hold 4 litres across all models, whilst dirty water capacity differs—3 litres for the CurvX, 3.5 litres for the others. These variations likely reflect internal base design differences rather than functional compromises.
None of the models includes detergent dispensers or UV sterilisation. Plumbing connection kits aren't available either, so you'll be refilling and emptying tanks manually regardless of which model you choose.
Physical Dimensions
The CurvX's retractable LiDAR enables its exceptionally low 79.8 mm height, allowing it to clean beneath furniture that would trap the Edge S5A (98 mm) or S5V (96.5 mm). For homes with low-clearance sofas, beds, or cabinets, this 18-20 mm difference expands the cleanable area considerably.
Diameter remains essentially identical across all three at approximately 353 mm. The robots themselves occupy similar floor space, but base dimensions tell a different story. The CurvX base measures 450 mm in all dimensions—a perfect cube—whilst the Edge S5A and S5V bases are narrower (340 mm) but deeper (487 mm) and taller (521 mm). The CurvX base demands more floor area but less vertical clearance.
Real-World Application
The CurvX suits larger properties where its extended battery life, superior suction, and advanced navigation justify the premium. Homes with pets benefit enormously from its 108-object recognition and dedicated animal detection, whilst the low profile proves invaluable in furniture-dense environments. The remote camera access adds security monitoring capabilities beyond simple cleaning.
The Edge S5A targets users wanting robust performance without flagship pricing. Its 18,500 Pa suction handles most challenges effectively, and dirt detection ensures thorough mopping results. The standard height may limit under-furniture access, but for properties without particularly low clearances, this rarely matters. It's well-suited to medium-sized homes with mixed flooring.
The S5V serves as the accessible entry point. Its 12,000 Pa suction manages hard floors and light carpets adequately, though thick pile or heavy soiling may challenge it. Without dirt detection or side brush extension, it cleans methodically rather than intelligently, but the multifunctional base still delivers proper mop maintenance. Smaller flats or homes with predominantly hard flooring will find it perfectly adequate.
Conclusion: Which to Choose?
Choose the Roborock Qrevo CurvX if you're managing a large property exceeding 150 square metres, need to clean beneath low-clearance furniture regularly, have pets requiring advanced obstacle recognition, or value remote monitoring through the camera system. The investment delivers the most sophisticated robot vacuum technology currently available, with navigation and intelligence that genuinely enhance daily convenience.
Choose the Roborock Qrevo Edge S5A if you want premium cleaning performance without flagship features you won't use. The 18,500 Pa suction and dirt detection provide excellent results in medium-sized homes, and the slightly taller profile rarely causes practical issues unless you have unusually low furniture. It represents the sweet spot between capability and value.
Choose the Roborock Qrevo S5V if you're prioritising budget whilst still wanting a multifunctional base with hot water washing and heated drying. It suits smaller properties with predominantly hard floors, where the lower suction and absent intelligent features won't compromise results. The cleaning fundamentals remain solid even without the premium refinements.
