Introduction
Roborock leads the global robot vacuum market with a wide range spanning from accessible models to high-end equipment with cutting-edge technology. In this selection we find three proposals from the brand launched between 2024 and 2025: the Roborock Qrevo Edge S5A, the Roborock S8 MaxV Ultra and the newly arrived Roborock Saros 10R. All three share the philosophy of offering complete autonomous cleaning with multifunctional bases, but present notable technical differences that orient them towards different user profiles.
The Qrevo Edge S5A and the Saros 10R stand out for their suction power of 18,500 Pa, whilst the S8 MaxV Ultra remains at 10,000 Pa. The most recent model, the Saros 10R from 2025, incorporates advances in navigation, battery capacity and mopping functions that position it as the most complete of the three. For homes with pets, thick carpets or the need to pass under low furniture, the differences in robot height, brush type and lifting systems are determining factors.
Power and Suction
Suction power marks an important difference between these models. The Roborock Qrevo Edge S5A and the Roborock Saros 10R reach 18,500 Pa, almost double the 10,000 Pa of the Roborock S8 MaxV Ultra. This difference translates into greater capacity to extract embedded dirt from long-pile carpets or vacuum heavy particles such as sand or dry soil.
Regarding the brushing system, the Qrevo Edge S5A and the Saros 10R mount the DuoDivide Antienredos brush, designed to push hair and strands towards the central suction gap, reducing tangles. The S8 MaxV Ultra equips a dual rubber brush, also effective against tangles but with a different approach. All three include an extendable side brush to improve cleaning in corners.
The anti-tangle side brush is present in the Qrevo Edge S5A and the Saros 10R, but not in the S8 MaxV Ultra. This may be relevant in homes with pet hair, where side brushes tend to accumulate tangles over time.
Regarding lifting, the S8 MaxV Ultra and the Saros 10R can raise the main brush when mopping, preventing it from dragging wet dirt across the floor. The Qrevo Edge S5A does not have this function. Additionally, the Saros 10R is the only one that also raises the side brush during mopping, maximising the separation between vacuuming and mopping.
Mopping
The mopping system varies between the three units. The Qrevo Edge S5A and the Saros 10R use two rotating mops, whilst the S8 MaxV Ultra employs a vibrating mop. Rotating mops usually offer better results on stuck-on stains thanks to constant rotary movement.
Regarding edge extension, the Qrevo Edge S5A and the Saros 10R extend the mops towards the edges, whilst the S8 MaxV Ultra has a mini side mop that fulfils a similar function. Mop lifting also differs: the S8 MaxV Ultra reaches 20 mm, the Saros 10R between 12 and 22 mm as needed, and the Qrevo Edge S5A remains at 10 mm. Greater lifting is useful in homes with high carpets or thresholds.
The Roborock Saros 10R introduces warm water for mopping the floor, a novelty compared to the cold water of the other two models. Warm water improves the dissolution of grease and difficult stains, especially in kitchens. Furthermore, the Saros 10R is the only one that automatically removes the mops at the base when only vacuuming is desired, avoiding having to remove them manually.
All three robots detect dirt both on the mops and on the floor, adjusting washing and scrubbing as needed. This function is practical for high-traffic areas or specific spills.
Navigation System
The navigation system shows notable differences. The Qrevo Edge S5A mounts a traditional LiDAR turret, whilst the S8 MaxV Ultra integrates a LiDAR turret with dual AI camera and front 3D laser sensor. The Saros 10R takes a leap with StarSight 2.0, which combines LiDAR, dual AI camera and 3D laser sensor in a more advanced system.
Obstacle recognition capacity also varies. The S8 MaxV Ultra identifies 73 types of objects, the Saros 10R extends to 108, whilst the Qrevo Edge S5A does not specify a specific number. Pet recognition is present in S8 MaxV Ultra and Saros 10R, allowing tracking and photos of pets, a function absent in the Qrevo Edge S5A.
Remote camera access and night vision LED are only available on the S8 MaxV Ultra and the Saros 10R. This allows monitoring the home in real time from the app, a useful function for security or pet supervision. The Qrevo Edge S5A lacks an AI camera, so it does not offer these possibilities.
All three units incorporate intelligent cleaning with SmartPlan, but AI stain recognition only works on the S8 MaxV Ultra and the Saros 10R. This function detects visible stains and automatically adjusts mopping intensity in that area.
Autonomy and Battery
Battery capacity marks clear differences. The Roborock Saros 10R equips 6,400 mAh, compared to the 5,200 mAh of the Qrevo Edge S5A and the S8 MaxV Ultra. Despite this difference, all three offer 180 minutes of declared autonomy, which suggests that the Saros 10R manages energy more efficiently or that its larger battery compensates for the consumption of additional functions such as warm water.
In practice, 180 minutes allow cleaning homes of up to 200-250 m² in a single cycle, provided there are not too many obstacles or complex areas. The greater capacity of the Saros 10R offers additional margin for extended sessions or large homes.
Smart Functions
The ability to overcome obstacles is similar in Qrevo Edge S5A and S8 MaxV Ultra, with 20 mm of clearable height. The Saros 10R introduces a simple step system that improves this capacity, although the table does not detail the exact height. This is useful for thresholds, thick carpets or small level differences between rooms.
The own voice assistant is present in the S8 MaxV Ultra and the Saros 10R, allowing commands to be given directly to the robot without going through Alexa or Google Home. The Qrevo Edge S5A only supports external assistants. All three are compatible with Alexa and Google Home.
Multifunctional Cleaning Base
All three robots include a multifunctional base with auto-emptying, mop washing and drying. Washing is carried out with hot water in all three cases, improving mop hygienisation. Drying also uses hot air in all, speeding up the process and preventing bad odours.
Self-cleaning of the washing tray version 2.0 is present in the Qrevo Edge S5A and the Saros 10R, but not in the S8 MaxV Ultra. This function automatically cleans the tray where the mops are washed, reducing manual maintenance.
The detergent tank in the base is available on the S8 MaxV Ultra and the Saros 10R, but not on the Qrevo Edge S5A. This allows the base to dispense detergent automatically during mop washing, improving cleaning without user intervention.
Dust bag capacity varies slightly: 2.7 litres in the Qrevo Edge S5A versus 2.5 litres in the other two. The clean water tank is 4 litres in all, whilst the dirty water tank is 3.5 litres in Qrevo Edge S5A and S8 MaxV Ultra, and 3 litres in the Saros 10R. These differences are minimal in real use.
Dimensions
Robot height is determining for passing under furniture. The Roborock Saros 10R measures 79.8 mm, the Qrevo Edge S5A reaches 98 mm and the S8 MaxV Ultra reaches 103 mm. This difference of more than 2 cm between the Saros 10R and the S8 MaxV Ultra can determine whether or not the robot accesses under sofas, beds or low furniture.
The diameter is practically identical in all three: 352-353 mm. The robot's dust bin varies: 325 ml in the Qrevo Edge S5A, 270 ml in the other two. The robot's water tank is 80 ml in the Qrevo Edge S5A, 100 ml in the S8 MaxV Ultra and 69 ml in the Saros 10R. These differences have little real impact, given that all three have multifunctional bases that manage water and dust.
Base dimensions also vary. The S8 MaxV Ultra is the widest (409 mm), followed by the Saros 10R (381 mm) and the Qrevo Edge S5A (340 mm). In height, the Qrevo Edge S5A is the tallest (521 mm), compared to 488 mm for the Saros 10R and 470 mm for the S8 MaxV Ultra. It is advisable to measure the available space before deciding, especially if you plan to place the base in a cupboard or recess.
Real-world experience
For large or multi-level homes, the Roborock Saros 10R offers clear advantages: greater battery, reduced height to access under more furniture and improved step-climbing capability. Its StarSight 2.0 navigation system with 108 recognised obstacles also provides precision in complex environments.
In homes with pets, both the S8 MaxV Ultra and the Saros 10R include specific animal recognition and anti-tangle brushes. The greater suction power of the Saros 10R (18,500 Pa) is advantageous for hair embedded in carpets. The Qrevo Edge S5A, despite its high power, lacks pet recognition.
If maximum maintenance autonomy is sought, the Saros 10R stands out for its tray self-cleaning 2.0, automatic mop removal and warm water for mopping. These functions reduce manual interventions. The S8 MaxV Ultra also offers a good level of automation, although without mop removal or warm water.
For users who value home surveillance or pet tracking, the remote camera access of the S8 MaxV Ultra and the Saros 10R is attractive. The Qrevo Edge S5A does not offer this possibility as it lacks an AI camera.
Conclusion: Which to choose?
Choose the Roborock Qrevo Edge S5A if you are looking for a powerful robot (18,500 Pa) with complete multifunctional base at a more competitive price, you do not need a surveillance camera or pet recognition, and your home does not have extremely low furniture. The tray self-cleaning 2.0 and its greater dust bag capacity (2.7 L) are points in favour for reducing maintenance.
