Specifications are based on manufacturer information. Actual cleaning results and battery life will depend on your home, floor types and selected settings.
1. Suction Power and Vacuuming
Roborock Qrevo S5V
The Qrevo S5V offers up to 12,000Pa of advertised suction, designed to collect everyday dust, crumbs, dirt and hair from hard floors and carpets.
Its DuoDivide main brush uses two parallel rollers to direct hair towards the central dustbin inlet. Combined with its anti-tangle side brush, this design aims to reduce hair wrapping and simplify maintenance.
For households that need regular vacuuming rather than a long list of premium extras, the S5V has a strong specification.
Roborock Qrevo Edge 2
The Qrevo Edge 2 increases advertised suction to 25,000Pa. It also features the DuoDivide main brush and FlexiArm Arc side brush, designed to improve hair collection and cleaning around edges.
The higher suction figure makes it the more powerful model on paper. However, suction ratings alone don’t determine real-world performance; brush design, airflow, flooring and cleaning settings all matter.
Winner: Roborock Qrevo Edge 2. It has substantially higher advertised suction, although that doesn’t mean it will clean every surface twice as well.
2. Mopping Performance
Both models use dual spinning mop pads and docks that automate routine mop maintenance.
The Qrevo S5V includes FlexiArm edge mopping, which helps the mop reach along suitable edges. Its dock washes the mop pads and dries them using warm air.
The Qrevo Edge 2 builds on this with an upgraded mopping system, additional dirt-detection features and hot-water mop washing at up to 80°C.
These features could appeal if you have extensive hard flooring or want more automated cleaning and maintenance. Neither robot should be treated as a guaranteed replacement for manually tackling every dried-on stain.
Winner: Roborock Qrevo Edge 2. Its upgraded mopping features give it the advantage on specifications.
3. Navigation and Obstacle Avoidance
The Qrevo S5V uses PreciSense LiDAR navigation and Reactive Tech obstacle avoidance. Through the Roborock app, you can manage maps, select rooms, schedule cleaning and set no-go zones.
The Qrevo Edge 2 uses a retractable LiDAR system and Reactive AI obstacle recognition. Its camera and structured-light system are designed to identify and avoid a wider range of everyday objects.
That could be useful in busy homes where toys, cables and other objects sometimes end up on the floor. However, no robot vacuum can reliably avoid every obstacle, so it’s still worth clearing loose items before cleaning.
Winner: Roborock Qrevo Edge 2. It offers the more advanced obstacle-recognition system.
4. Design and Cleaning Under Furniture
One of the biggest practical differences is the robot’s height.
The Qrevo S5V measures approximately 9.65cm tall, while the Qrevo Edge 2 measures just 7.98cm.
That makes the Edge 2 around 1.67cm shorter, which could help it clean beneath beds, sofas and cabinets that have limited clearance.
Both models need suitable space for their multifunctional docks, so remember to measure the available floor space as well as the clearance beneath your furniture.
Winner: Roborock Qrevo Edge 2. Its slimmer design makes it the better option for suitable low-clearance spaces.
5. Dock Features and Maintenance
Both models are designed to reduce the effort involved in looking after a robot vacuum. Their multifunctional docks automate dust emptying, mop washing, mop drying and water refilling.
The Edge 2 adds hot-water mop washing at up to 80°C and a self-cleaning dock system.
Neither model is completely maintenance-free. You’ll still need to refill and empty water tanks, replace dust bags when required, clean filters and inspect the brushes.
Winner: Roborock Qrevo Edge 2. Its dock offers more advanced mop-washing features, although the S5V already provides useful everyday automation.
6. Alexa and Smart-Home Compatibility
Both models support compatible third-party voice controls alongside their respective app features.
If you mainly want to start supported cleaning functions using Alexa, neither model has a clear advantage over the other. Both also let you manage schedules and cleaning settings through the Roborock app.
Winner: Draw. Both are worth considering for an Alexa-compatible smart home.
7. Which Offers Better Value for Money?
The Qrevo S5V is generally positioned below the Qrevo Edge 2 in Roborock’s UK range, although prices and discounts can change.
The S5V may offer better value if you want automated vacuuming and mopping without paying extra for a slimmer body and the Edge 2’s upgraded features.
The Edge 2 may justify the extra cost if you have pets, need to clean beneath low furniture or want its more advanced mopping and obstacle recognition.
Before buying, compare the current prices of the exact models and check the seller, delivery details and warranty.
