Introduction
Roborock maintains its leadership in the robot vacuum sector with two 2024 proposals that represent different philosophies within the high-end range. The Roborock Qrevo Edge S5A arrives as a commitment to raw power and operational simplicity, whilst the Roborock S8 MaxV Ultra positions itself as a more complete model in terms of artificial intelligence and recognition capabilities.
Both units feature a multifunction base that washes and dries the mops, which guarantees efficient mopping in either case. The choice between one or the other will depend on whether you prioritise suction power and certain mechanical improvements, or prefer a more sophisticated navigation system with camera and advanced obstacle recognition.
Power and Suction
The most striking difference between these two Roborock robots lies in suction power. The Qrevo Edge S5A reaches 18500 Pa, a figure that practically doubles the 10000 Pa of the S8 MaxV Ultra. In practice, this translates into greater capacity to extract ingrained dirt from carpets or pick up heavy particles in a single pass.
The main brushing system also presents important variations. The Qrevo Edge S5A features the DuoDivide anti-tangle system, designed to push hairs towards the central suction gap and minimise tangles. The S8 MaxV Ultra uses a dual silicone brush, which equally reduces tangles but with a different approach. Both systems are effective, although the DuoDivide usually stands out in homes with long-haired pets.
A clear advantage of the S8 MaxV Ultra is that it can raise its main brush during mopping, something the Qrevo Edge S5A does not do. This allows the S8 MaxV Ultra to mop without dragging dry dirt with the brush, keeping the mops cleaner for longer.
As for the side brush, both models feature extension to improve cleaning in corners. The difference is that the Qrevo Edge S5A incorporates anti-tangle technology in this side brush, whilst the S8 MaxV Ultra does not include it. For homes with pet hair or human hair, this can make a difference in maintenance.
Mopping
The Qrevo Edge S5A opts for two rotating mops with FlexiArm system, which extends one of the mops to better reach edges and corners. The S8 MaxV Ultra uses VibraRise 3.0 vibrating mop with a mini side mop that also seeks to improve coverage in difficult areas. These are different approaches: rotating mops usually exert more pressure and are more effective on adhered dirt, whilst vibration combined with the robot's movement can be more delicate with sensitive floors.
Mop lifting differs significantly. The S8 MaxV Ultra can raise them up to 20 mm, sufficient to pass over medium-thickness carpets without wetting them. The Qrevo Edge S5A stays at 10 mm, which works well with thin carpets but may be insufficient with thicker carpets.
Mop washing in the base is where the Qrevo Edge S5A makes a difference. It washes the mops at 75°C, a temperature that helps eliminate grease and bacteria more effectively than the standard hot water of the S8 MaxV Ultra. Additionally, mop drying is also superior in the Qrevo Edge S5A, which dries them at 45°C compared to the unspecified temperature hot air of the S8 MaxV Ultra. This can reduce bad odours and bacterial growth between cleaning cycles.
Both models detect dirt both on the mops and on the floor, automatically adjusting mopping intensity or going back over particularly dirty areas. Neither allows leaving the mops in the base automatically to perform vacuuming only, which requires manually removing them if you don't want to mop.
Navigation System
Both robots use 3D Lidar turret to map the home with precision, but the S8 MaxV Ultra takes a qualitative leap by incorporating dual camera with artificial intelligence and a front 3D laser sensor. This allows it to recognise up to 73 different types of obstacles, including pets, and avoid them with greater precision than the Qrevo Edge S5A.
Remote camera access is exclusive to the S8 MaxV Ultra, which allows using it as a surveillance device when not cleaning. The night vision LED is also present only in this model, improving navigation in low-light conditions.
The Qrevo Edge S5A compensates for the absence of camera with the SmartPlan 2.0 system, a more updated version than the SmartPlan 1.0 of the S8 MaxV Ultra. Although it cannot recognise objects visually, SmartPlan 2.0 optimises cleaning routes with greater efficiency according to usage data and home layout.
AI stain recognition is exclusive to the S8 MaxV Ultra, which can identify areas with greater dirt and automatically adjust power or number of passes. The Qrevo Edge S5A detects dirt, but without the level of visual detail provided by the camera.
Autonomy and Battery
Both robots feature a 5200 mAh battery that offers up to 180 minutes of autonomy. With this capacity they can cover large homes without needing intermediate recharges, which is especially useful in houses of more than 150 m².
The difference in suction power could make the Qrevo Edge S5A consume more battery in maximum power modes, although in practice both models manage energy well by adjusting power according to the type of floor detected.
Smart Features
The ability to overcome obstacles is identical in both: 20 mm height. This allows them to navigate thick cables, medium-thickness carpets and small level changes without getting stuck.
The S8 MaxV Ultra includes a simple built-in voice assistant, which allows giving basic commands directly to the robot without going through the app. The Qrevo Edge S5A does not have this function, although both are compatible with external voice assistants such as Alexa or Google Assistant.
Multifunction Cleaning Base
Both multifunction bases perform dust auto-emptying, mop washing and drying. The dust bag capacity is slightly higher in the Qrevo Edge S5A, with 2.7 litres compared to the 2.5 litres of the S8 MaxV Ultra. The clean and dirty water tanks are identical: 4 litres and 3.5 litres respectively.
Self-cleaning of the washing tray is a clear advantage of the Qrevo Edge S5A, which incorporates the 2.0 system already installed from the factory. This means that the base itself cleans after washing the mops, drastically reducing manual maintenance. The S8 MaxV Ultra does not include this function, which requires periodically cleaning the tray by hand.
The detergent tank is present only in the S8 MaxV Ultra, allowing automatic dosing of cleaning product during mop washing. The Qrevo Edge S5A does not have this option, although it compensates with the higher washing and drying temperatures we mentioned earlier.
Neither model includes UV disinfection nor direct connection to water pipes, although they don't offer an optional kit for this either.
Dimensions
The diameter of both robots is practically identical: 352 mm for the Qrevo Edge S5A and 353 mm for the S8 MaxV Ultra. The important difference is in height: the Qrevo Edge S5A measures 98 mm, compared to the 103 mm of the S8 MaxV Ultra. Those 5 mm can be decisive for passing under certain low furniture, sofas or beds with little clearance from the floor.
As for the bases, the Qrevo Edge S5A is taller and deeper (521 mm height and 487 mm depth), whilst the S8 MaxV Ultra is wider (409 mm) but less tall (470 mm) and less deep (419 mm). It's advisable to measure the available space before deciding, especially if you plan to place the base in a corner or under furniture.
The robot's dust bin also varies: 325 ml in the Qrevo Edge S5A compared to 270 ml in the S8 MaxV Ultra. The internal water tank is larger in the S8 MaxV Ultra (100 ml compared to 80 ml), although this difference is hardly relevant given that both return to the base to refill during mopping.
Real-World User Experience
The Qrevo Edge S5A is designed for those seeking maximum suction power and minimum maintenance. Its superior vacuuming capacity makes it ideal for homes with carpets, pets or high traffic. The 2.0 self-cleaning system of the tray notably reduces maintenance tasks, and the elevated temperatures in mop washing and drying guarantee hygiene without effort.
The S8 MaxV Ultra is aimed at users who value artificial intelligence and remote control. The dual camera and recognition of 73 obstacles, including pets, make it a more sophisticated option for homes with many objects on the floor or with animals that may interact with the robot. The ability to access the camera remotely adds a security and surveillance bonus.
In homes with thick carpets, the S8 MaxV Ultra has the advantage thanks to the 20 mm mop lifting and the ability to raise the main brush. The Qrevo Edge S5A may have problems with carpets thicker than 10 mm during mopping.
For houses with low furniture, the 98 mm height of the Qrevo Edge S5A can make the difference compared to the 103 mm of the S8 MaxV Ultra. In spaces with good lighting, the absence of camera in the Qrevo Edge S5A poses no major problem, but in homes with dark areas or night-time cleaning, the LED of the S8 MaxV Ultra proves useful.
