Introduction
The Roborock Qrevo Curv S5X and Roborock Qrevo Edge S5A represent two premium offerings from Roborock's 2024 lineup, both positioned at the higher end of the market. These models share an impressive array of technical specifications, making this a particularly nuanced comparison for anyone trying to decide between them. Both deliver 18,500 Pa of suction power and feature identical navigation systems, making them suitable for demanding cleaning scenarios across medium to large homes.
What makes this comparison interesting is that whilst these robots share most of their core technology, the differences that do exist relate primarily to the base station design and capacity. Understanding these distinctions becomes crucial when considering long-term convenience and how frequently you'll need to maintain the system. For homes with multiple floor types and regular cleaning demands, both options offer sophisticated solutions.
Differences Key in a Glance
- The Qrevo Edge S5A features a larger dustbag capacity at 2.7 litres versus 2.5 litres in the Curv S5X
- Dirty water tank capacity differs: 3.5 litres in the Edge S5A compared to 3 litres in the Curv S5X
- Base station dimensions vary significantly: the Curv S5X has a square footprint of 450mm in all directions, whilst the Edge S5A measures 340mm wide, 521mm tall, and 487mm deep
Suction and Brushwork
Both models deliver identical suction performance at 18,500 Pa, placing them firmly in the high-power category for 2024. This level of suction handles everything from fine dust on hard floors to embedded debris in carpets without breaking stride.
The DuoDivide anti-tangle main brush appears on both robots. This system pushes hair towards the central suction channel rather than wrapping it around the roller, which proves particularly effective for households with long hair or shedding pets. In practice, this means considerably less time spent cutting tangled hair from the brush bar.
Each robot includes an extendable side brush that reaches into corners more effectively than fixed designs. The side brushes also feature anti-tangle technology and neither model elevates them during mopping. This consistent approach to edge cleaning ensures both the Curv S5X and Edge S5A tackle skirting boards and room perimeters with similar effectiveness.
Mopping Performance
The mopping systems are identical across both models. Each uses dual rotating mops that extend to reach edges and corners, with 10mm lift capability to protect carpets and rugs. The mops spin rather than simply drag across floors, which generates better cleaning action on stubborn marks.
Both robots detect dirt on the floor and on the mops themselves, triggering additional cleaning passes or return trips to the base for mop washing when needed. This adaptive approach means the system responds to actual cleaning requirements rather than following a rigid pattern regardless of floor condition.
Neither model offers hot water mopping on the floor itself—both use cold water during the cleaning cycle. The bases do wash the mops with hot water and dry them with heated air, which helps prevent bacterial growth and odours between cleaning sessions. Neither robot automatically dismounts its mops at the base for vacuum-only operation, so you'll need to remove them manually if you only want to vacuum.
Navigation System
Navigation technology is identical between these models. Both employ a 3D LiDAR turret for mapping and obstacle avoidance, paired with the RR Mason 11.0 processing system and SmartPlan 2.0 intelligent cleaning algorithms.
Neither robot includes a front-facing camera, AI-powered object recognition, pet detection, or night vision LEDs. They also lack remote camera access functionality. The navigation relies entirely on laser-based mapping and basic obstacle sensors, which proves sufficient for most home environments but won't identify specific objects or allow you to check on pets remotely.
Both models handle obstacles up to 20mm high, allowing them to mount typical door thresholds and transition between different flooring types without assistance.
Battery Life and Coverage
Battery specifications match exactly: 5,200 mAh capacity delivering approximately 180 minutes of runtime. This autonomy suits homes of various sizes, as both robots will return to base for recharging if needed before resuming where they left off.
The combination of high suction power and substantial battery capacity means these models can tackle thorough cleaning sessions without compromising on performance to extend runtime. For most residential properties, 180 minutes provides ample time to complete a full clean cycle.
Smart Features
Both robots integrate with external voice assistants including Alexa and Google Home, allowing voice control of basic functions. Neither includes its own proprietary voice assistant or robotic arm functionality.
The SmartPlan 2.0 system on both models analyses your home layout and cleaning patterns to optimise routes and schedules. This intelligence operates identically across both the Curv S5X and Edge S5A.
Multifunctional Base Station
Here's where the practical differences emerge. Both bases auto-empty the robot's dustbin, wash the mops with hot water, and dry them using heated air. Both feature the 2.0 version of Roborock's self-cleaning tray system, which maintains the base's hygiene automatically.
The Qrevo Edge S5A offers a slightly larger dustbag at 2.7 litres compared to 2.5 litres in the Curv S5X. This translates to perhaps one or two extra weeks between bag changes, depending on your home's dust levels and cleaning frequency. Similarly, the dirty water tank capacity of 3.5 litres in the Edge S5A versus 3 litres in the Curv S5X means marginally less frequent emptying after mopping sessions.
Clean water capacity remains identical at 4 litres for both bases. Neither base includes a detergent dispenser, UV disinfection, or the ability to connect to household plumbing—and no optional connection kit exists for these models.
Physical Dimensions
The robots themselves are identical: 352mm diameter and 98mm tall. This height allows them to slip under most furniture whilst the diameter remains typical for high-performance models with LiDAR turrets.
Base station footprints differ noticeably. The Qrevo Curv S5X features a compact square design measuring 450mm in all three dimensions—width, height, and depth. The Qrevo Edge S5A adopts a slimmer but taller profile: 340mm wide, 521mm tall, and 487mm deep. The Curv's square footprint might suit corner placement better, whilst the Edge's narrower width could fit more easily against walls in tighter spaces. The Edge S5A's extra height requires more vertical clearance, which matters if you're considering placing it under counters or in cupboards.
Real-World Usage Scenarios
For larger homes generating more dust and requiring frequent mopping, the Edge S5A's marginally larger waste capacities reduce maintenance frequency slightly. The difference isn't dramatic—we're talking perhaps an extra week or two between interventions—but it does add up over time.
Homes with pets benefit equally from both models thanks to the DuoDivide brush and strong suction. The anti-tangle design genuinely reduces the frustration of hair maintenance, and the 18,500 Pa suction handles pet hair on various surfaces effectively.
Both robots perform identically on hard floors, tiles, and carpets given their matching specifications. The 10mm mop lift protects rugs adequately, and the dirt detection ensures thorough cleaning without unnecessary repetition.
Installation space matters more than you might initially think. The Curv S5X's square base fits neatly into corners but demands that 450mm cube of space. The Edge S5A's slimmer profile suits narrower alcoves but requires more headroom. Measure your intended location carefully before deciding.
Conclusion: Which to Choose?
Choose the Roborock Qrevo Curv S5X if you prefer a more compact base footprint that fits well in corner locations, and the slightly smaller waste capacities won't inconvenience you. The square design can look tidier in certain room layouts, and the performance differences are negligible for most households.
Choose the Roborock Qrevo Edge S5A if you value the extra dustbag and dirty water capacity, even if the difference seems modest on paper. For busy households cleaning frequently or larger homes, those additional litres mean fewer interruptions for maintenance. The slimmer width also suits installations where horizontal space is limited, provided you have sufficient vertical clearance.
For homes with multiple pets or high foot traffic, the Edge S5A's larger capacities justify the choice. If you're working with tight spatial constraints, carefully measure both base options—the Curv's cube versus the Edge's tower design will suit different spaces better. Beyond these considerations, you're choosing between two exceptionally similar robots where the base station design represents the primary decision point.
