Introduction
Roborock has positioned itself as the leading manufacturer in the robot vacuum market, and these three models demonstrate why. The Roborock Qrevo Curv S5X and Roborock Qrevo Edge S5A arrived in 2024, whilst the Roborock Qrevo CurvX represents the brand's 2025 flagship. All three incorporate multifunctional bases with mop washing and drying capabilities, DuoDivide anti-tangle brush technology, and rotating dual mops that extend to clean edges.
The CurvX stands out as the most advanced option, featuring a retractable LiDAR system that reduces its height to just 79.8 mm, dual AI cameras, and enhanced autonomy. The S5X and Edge S5A share similar specifications but differ in base design and capacity. These are premium models designed for users seeking minimal intervention cleaning with professional-grade mopping results.

Power and Suction
The Roborock Qrevo CurvX takes the lead with 22,000 Pa suction power, a considerable jump from the 18,500 Pa offered by both the S5X and Edge S5A. In practice, this translates to more effective deep carpet cleaning and better performance on stubborn debris.
All three models employ the DuoDivide anti-tangle brush system, which channels hair and fibres towards the central suction opening rather than wrapping them around the roller. This design proves particularly valuable in homes with pets or long-haired residents, as it dramatically reduces maintenance time.
The CurvX introduces a unique advantage: its main brush can elevate during mopping sessions, preventing wet debris from being dragged across clean floors. Neither the S5X nor the Edge S5A include this feature, meaning their brushes remain in contact with the floor throughout mopping cycles.
Each model features an extendable side brush that reaches into corners more effectively, and all incorporate anti-tangle technology on this component as well. None of the three can raise the side brush when mopping, so it continues spinning regardless of the cleaning mode selected.
Mopping
All three models use rotating dual mops that extend to reach edges and skirting boards—a feature that makes a tangible difference when cleaning along walls. The mops retract when navigating carpets or rugs, though the extent of elevation varies significantly.
The Qrevo CurvX offers adaptive mop lift ranging from 7 to 17 mm, adjusting to different floor transitions and carpet pile heights. The S5X and Edge S5A provide a fixed 10 mm lift, which handles most standard rugs but may struggle with thicker carpets. This adaptive capability on the CurvX means it can tackle more diverse floor layouts without manual intervention.
Each model returns to its base during cleaning to wash the mops with hot water at 60°C, ensuring they're always cleaning with fresh pads rather than spreading dirt around. After completing the job, the base dries the mops using hot air—a critical feature for preventing odours and bacterial growth.
Dirt detection works on two levels across all models: sensors monitor both the mop cleanliness and the floor condition, triggering additional passes or mop washes when necessary. None of the three can automatically remove their mops at the base for vacuum-only sessions, so you'll need to detach them manually if you want pure suction cleaning.
Navigation System
Here's where the Roborock Qrevo CurvX truly distinguishes itself. Its retractable LiDAR system lowers the robot's profile to 79.8 mm, allowing it to slip beneath furniture that would block the S5X or Edge S5A with their 98 mm height and traditional LiDAR towers.
The CurvX incorporates dual AI cameras paired with a 3D laser sensor at the front, creating a comprehensive obstacle detection system that recognises 108 different objects—including pets, which it can identify and avoid disturbing. The S5X and Edge S5A lack cameras entirely, relying solely on their LiDAR and basic sensors for navigation. This means they won't recognise your sleeping dog or distinguish between a sock and a cable.
Remote camera access on the CurvX lets you check on your home through the robot's cameras via the app, and the integrated LED provides night vision capabilities. These surveillance features simply don't exist on the other two models.
All three run Roborock's Mason 11.0 algorithm with SmartPlan AI for intelligent room-by-room cleaning strategies, so the fundamental navigation logic remains consistent. The difference lies in the sensory input quality feeding those decisions.
Battery and Autonomy
The Roborock Qrevo CurvX houses a 6,400 mAh battery delivering up to 220 minutes of runtime—enough for extensive properties without requiring a recharge mid-clean. The S5X and Edge S5A share a 5,200 mAh capacity with 180-minute autonomy, which remains perfectly adequate for most homes but may necessitate a charging break in larger dwellings.
That extra 40 minutes on the CurvX becomes particularly relevant when mopping, as the robot makes multiple trips to the base for mop washing. More battery capacity means fewer interruptions and faster completion of whole-home cleaning cycles.
Smart Functions
The Qrevo CurvX can climb simple steps, giving it access to rooms with minor level changes that would stop the other models. The S5X and Edge S5A manage 20 mm obstacles—sufficient for standard door thresholds and low-profile transitions but not genuine steps.
Voice control works differently across the range. Whilst all three respond to external assistants like Alexa and Google Home, only the CurvX features its own integrated voice assistant for direct commands without requiring a smart speaker.
Multifunctional Cleaning Base
Each model includes a multifunctional base that auto-empties dust, washes mops with 60°C water, and dries them with hot air. The key difference lies in the base self-cleaning system: the CurvX employs version 3.0 technology for maintaining the washing tray, whilst the S5X and Edge S5A use version 2.0. This upgrade on the CurvX should mean more thorough base maintenance with less manual intervention.
The S5X and CurvX share identical base dimensions at 450 mm in all directions, but the Edge S5A uses a different base design measuring 340 mm wide, 521 mm tall, and 487 mm deep. This taller, narrower profile might suit certain spaces better, though it occupies similar floor area.
Dust bag capacity sits at 2.5 litres for the S5X and CurvX, versus 2.7 litres on the Edge S5A—a marginal difference that translates to perhaps one extra week between bag changes. All three hold 4 litres of clean water, but the Edge S5A's dirty water tank is larger at 3.5 litres compared to 3 litres on the others. For households that mop frequently, this extra half-litre reduces the frequency of dirty water disposal.
None of the models include detergent dispensers or UV disinfection, nor can they connect to plumbing for automatic water refilling. There's no kit available for retrofitting this capability either.
Dimensions
The Roborock Qrevo CurvX measures just 79.8 mm tall thanks to its retractable LiDAR, making it the clear choice for homes with low-clearance furniture. The S5X and Edge S5A both stand 98 mm high—still reasonable but unable to access spaces beneath many sofas and beds.
All three span approximately 352-353 mm in diameter, so they navigate through doorways and around furniture legs with equal ease. The CurvX's reduced height doesn't come at the expense of width, maintaining the same footprint as its siblings.
The onboard dust capacity differs slightly: 325 ml on the S5X and Edge S5A versus 258 ml on the CurvX. Similarly, water deposits measure 80 ml on the first two and 69 ml on the CurvX. These smaller onboard tanks on the CurvX likely result from the space required for its advanced camera and sensor array, though it matters little since all models return to the base regularly during operation.
Real-World Experience
For larger properties, the Roborock Qrevo CurvX's extended battery life and superior suction make it the most capable option, completing whole-home cleans more quickly and with less intervention. Its ability to slip beneath low furniture adds genuine value in homes with modern, low-profile sofas or beds.
Pet owners will find the CurvX's animal recognition particularly useful—the robot can avoid disturbing sleeping pets and navigate around their bowls and toys more intelligently. The DuoDivide brush system across all models handles pet hair excellently, but only the CurvX has the visual intelligence to work around animals themselves.
The S5X and Edge S5A deliver essentially identical cleaning performance on hard floors and standard carpets. The Edge S5A's slightly larger base tanks suit households that mop frequently and prefer emptying dirty water less often, whilst its different base footprint might fit certain spaces better.
All three handle the full spectrum from hard floors to carpets competently, with hot water mop washing and drying ensuring genuinely clean floors rather than just redistributing dirt. The adaptive mop lift on the CurvX provides more flexibility with varied floor types, particularly thick rugs.
