Introduction
Roborock presents three models competing within its own family: the Qrevo Edge S5A launched in 2024, and two more recent options from 2025, the Qrevo S5V and the QV 35A. All three share the philosophy of the world's leading robot vacuum brand, but with technical differences that define distinct usage profiles.
The Qrevo Edge S5A positions itself as the most powerful of the three, with 18,500 Pascals of suction and advanced features that place it in the high-end range. The Qrevo S5V drops to 12,000 Pa whilst maintaining interesting functions, while the QV 35A, with 8,000 Pa, opts for simplicity without sacrificing the essentials. All integrate a multifunctional base with auto-emptying, mop washing and drying, which guarantees effective mopping compared to basic models.
Power and Suction
The most evident difference lies in suction capacity. The Roborock Qrevo Edge S5A reaches 18,500 Pa, a figure typical of the high-end range that allows extraction of ingrained dirt from carpets and vacuums competently on all types of surfaces. The Qrevo S5V remains at 12,000 Pa, sufficient for homes with hard floors and short-pile carpets, but with less margin on dense textiles. The QV 35A, with 8,000 Pa, covers basic daily vacuuming needs without complications.
Regarding the brushing system, all three are equipped with the DuoDivide anti-tangle brush on the Edge S5A and the S5V, designed to push hair towards the central suction gap and minimise tangles. The QV 35A mounts a simple brush, less sophisticated but functional. All three models include an anti-tangle side brush, although only the Edge S5A incorporates side extension to improve cleaning in corners and skirting boards.
None of the three raises the main brush or the side brush during mopping, something that some competing models do offer to avoid dragging wet dirt.
Mopping
All three robots use two rotating mops, an effective system that guarantees active mopping compared to simple dragged cloths. The Edge S5A and the S5V feature mop extension to better reach edges, whilst the QV 35A dispenses with this function. In practice, this is especially noticeable in narrow corridors and skirting boards.
Mop lift reaches 10 mm on all three models, sufficient to climb over thin carpets without wetting them. All mop with cold water from the robot's tank, but the difference comes in mop washing at the base: the Edge S5A washes with hot water, which improves the removal of grease and adhered stains, whilst the S5V and QV 35A do so with cold water.
Drying also varies. The Edge S5A dries the mops with hot air, speeding up the process and reducing the risk of bad odours. The other two models use cold air, less efficient but functional if the base is in a ventilated location.
A feature exclusive to the Edge S5A is dirt detection on both the mops and the floor. The robot identifies when the mops are dirty and returns to the base to wash them, or detects dirtier areas of the floor and automatically scrubs again. This makes a clear difference in homes with heavy traffic or pets.
Navigation System
All three robots mount a LiDAR turret to map the home and navigate with precision. All include obstacle avoidance and intelligent cleaning via SmartPlan, which optimises routes according to the layout of each room.
The Edge S5A integrates the RR Mason 11.0 processor, which gives it greater computing capacity and response to unforeseen events. On the other two models the chip is not specified, although they share the same basic navigation platform.
None incorporates an AI camera, front 3D laser sensor, pet recognition, curtain detection or night vision LED. Nor do they allow remote camera access. These are robots that prioritise laser navigation without additional complications.
Autonomy and Battery
All three models share a 5,200 mAh battery and 180 minutes of autonomy. This is more than sufficient for homes of up to 150-200 m² in a single cycle, even with active mopping. Recharging is carried out at the multifunctional base without the need for manual intervention.
Smart Functions
All overcome obstacles of up to 20 mm, which allows them to negotiate small unevenness, expansion joints or transitions between floors. None mounts a robotic arm or own voice assistant, although all three are compatible with Alexa and Google Home for external voice control.
Multifunctional Cleaning Base
All three bases auto-empty the dust container into a 2.7-litre bag, wash and dry the mops, and have 4-litre clean water and 3.5-litre dirty water tanks. This allows several mopping sessions without manually refilling or emptying.
The major difference lies in the self-cleaning of the washing tray. The Edge S5A incorporates the 2.0 system, which automatically cleans the tray where the mops are washed to prevent accumulation of dirt and bad odours. The other two models lack this function, which requires manual cleaning of the tray from time to time.
None includes UV disinfection, integrated detergent tank or connection to water pipes. Nor do they offer an optional kit for hydraulic installation.
Dimensions
The Edge S5A measures 352 mm in diameter and 98 mm in height. The S5V and QV 35A have 353 mm in diameter and 96.5 mm in height. The 1.5 mm difference in height may seem minimal, but in homes with low furniture it can determine whether or not the robot passes under sofas or beds with little clearance from the floor.
All three bases share measurements: 340 mm wide, 521 mm high and 487 mm deep. It's advisable to reserve an accessible space with a power socket nearby.
Real-World Usage Experience
The Qrevo Edge S5A is designed for demanding users seeking the best performance in large houses, with pets or with a need for deep mopping. The 18,500 Pa power, extendable side brush, dirt detection and hot water washing make it a complete option. The 2.0 tray self-cleaning reduces manual maintenance.
The Qrevo S5V is balanced for medium-sized homes without extreme complications. It maintains mop extension and a good level of suction, although washing with cold water and drying with cold air require somewhat more attention in base maintenance.
The QV 35A suits profiles seeking functionality without extras. With 8,000 Pa and without mop extension or extendable side brush, it performs in small flats or as a second robot on additional floors. The absence of dirt detection means the user must supervise the cleaning status more.
Conclusion: Which to Choose?
Choose the Roborock Qrevo Edge S5A if you're looking for the best robot vacuum 2025 within this robot vacuum comparison. It's the most complete option for large houses, with pets, thick carpets or if you value intelligent mopping with dirt detection. Hot water washing, hot air drying and 2.0 tray self-cleaning minimise maintenance. The extendable side brush improves cleaning in corners. Ideal if you want total autonomy and maximum performance.
Choose the Roborock Qrevo S5V if you prioritise a recent Roborock robot vacuum with good value for money. It maintains mop extension, DuoDivide anti-tangle brush and 12,000 Pa of suction, sufficient for most homes. It dispenses with dirt detection and hot water washing, but remains a solid option for medium-sized homes without dense carpets.
Choose the Roborock QV 35A if you're looking for a functional and simple Roborock robot vacuum. With 8,000 Pa and without mop extensions or side brush, it covers basic needs in small flats or as a complement on secondary floors. The more competitive price compensates for the absence of advanced functions. Perfect if you don't have pets with lots of hair or very demanding floors.
