Introduction
Roborock once again demonstrates its leadership in the sector with three models that represent the best of its technology across different ranges. The Roborock Qrevo Edge S5A and the Roborock Qrevo S5V, launched in 2024 and 2025 respectively, share the Qrevo family with rotating mop systems and multifunctional bases. The Roborock S8 MaxV Ultra from 2024 belongs to the S8 series, with a different approach to intelligent navigation and vibrating mop.
These Roborock robot vacuum cleaners are designed for users seeking total autonomy in cleaning. The differences between them mark distinct usage profiles: from the raw power of the Qrevo Edge to the artificial intelligence of the S8 MaxV Ultra, through to the balance of the Qrevo S5V.
Power and Suction
Suction power marks the most notable difference in this robot vacuum comparison. The Roborock Qrevo Edge S5A reaches 18,500 Pa, a figure that far exceeds the 12,000 Pa of the Qrevo S5V and the 10,000 Pa of the S8 MaxV Ultra. In practice, this translates to greater capacity to extract ingrained dirt from carpets and tile joints.
The brushing system varies according to the model. Both the Qrevo Edge S5A and the Qrevo S5V incorporate the DuoDivide anti-tangle brush, specifically designed to prevent hair and pet fur from wrapping around. The S8 MaxV Ultra features a dual silicone brush, also effective against tangles but with a different design.
The extendable side brush appears in the Qrevo Edge S5A and in the S8 MaxV Ultra, allowing better sweeping of corners. The Qrevo S5V does without this function. All three models include anti-tangle side brushes, although only the two Qrevo have this specific feature.
An exclusive advantage of the S8 MaxV Ultra is the lifting of the main brush during mopping, preventing it from getting unnecessarily wet. The Qrevo models do not lift the main brush.
Mopping
Here we find different philosophies. The Roborock Qrevo Edge S5A and the Qrevo S5V use two rotating mops at 200 RPM, a system that applies constant pressure and rotation to remove stuck-on stains. The S8 MaxV Ultra employs VibraRise 3.0 technology, a vibrating mop that works differently but equally effectively.
Both Qrevo models extend their mops to better reach edges, whilst the S8 MaxV Ultra incorporates a mini side mop for the same purpose. Mop lift differs: 10 mm in the Qrevo versus 20 mm in the S8 MaxV Ultra, which allows the latter to travel over thicker carpets without wetting them.
Mop washing in the base marks important differences. The Qrevo Edge S5A washes with hot water at 75°C, the highest temperature of the three, ideal for disinfecting and removing grease. The Qrevo S5V uses cold water, less effective against difficult stains. The S8 MaxV Ultra washes at 60°C, a middle ground.
Hot air mop drying is present in all three robots: 45°C in both Qrevo and 60°C in the S8 MaxV Ultra. Only the Qrevo Edge S5A includes tray self-cleaning 2.0, keeping the base more hygienic without manual intervention.
Dirt detection on mops and floor appears only in the Qrevo Edge S5A and the S8 MaxV Ultra, allowing particularly dirty areas to be automatically re-cleaned.
Navigation System
All three Roborock robot vacuum cleaners feature 360° LiDAR turret for precise mapping. However, the S8 MaxV Ultra adds additional layers of intelligence: dual AI camera, front 3D laser sensor and night vision LED. These functions allow it to recognise 73 types of obstacles, identify pets and offer remote camera access for surveillance.
The Qrevo Edge S5A and the Qrevo S5V lack a front camera and do not specifically recognise pets, although their obstacle avoidance works correctly. The exact number of obstacles they recognise is not specified.
Regarding intelligent cleaning, the Qrevo Edge S5A stands out with SmartPlan 2.0, an improved version compared to the SmartPlan 1.0 incorporated by both the Qrevo S5V and the S8 MaxV Ultra. The RR Mason 11.0 processor equips the Qrevo Edge S5A and the S8 MaxV Ultra.
AI stain recognition is only present in the S8 MaxV Ultra, which can visually identify dirt on the floor and adapt its cleaning.
Autonomy and Battery
All three models share a 5,200 mAh battery and 180 minutes of autonomy, sufficient for large homes. This equality in energy capacity means that performance differences are determined by other factors such as the suction power used or the type of surface.
Smart Functions
The ability to overcome steps is identical in all three: 20 mm in height, allowing movement between rooms with small level changes or climbing onto thick carpets without problems.
The S8 MaxV Ultra incorporates its own voice assistant, a function absent in the Qrevo models. All three are compatible with external assistants such as Alexa and Google Home.
Multifunctional Cleaning Base
All three bases include auto-emptying of the dust container, mop washing and drying. The dust bag capacity reaches 2.7 litres in the Qrevo versus 2.5 litres in the S8 MaxV Ultra, a minor difference in practice.
The clean and dirty water tanks are equal: 4 litres and 3.5 litres respectively. Only the S8 MaxV Ultra incorporates an integrated detergent tank, dispensing product during mop washing automatically.
The tray self-cleaning 2.0 of the Qrevo Edge S5A represents an advance in maintenance, by cleaning the area where the mops are washed. None of the three offers connection to plumbing or an optional kit for it.
Dimensions
The Qrevo Edge S5A measures 352 mm in diameter and 98 mm in height. The Qrevo S5V reaches 353 mm in diameter with 96.5 mm in height, the lowest of the three. The S8 MaxV Ultra has 353 mm in diameter but 103 mm in height, which may limit its access under very low furniture.
The robot's dust container varies slightly: 325 ml in the Qrevo Edge S5A, 330 ml in the Qrevo S5V and 270 ml in the S8 MaxV Ultra. The robot's water tank is 80 ml in the Qrevo versus 100 ml in the S8 MaxV Ultra.
The Qrevo bases are identical: 340 mm wide, 521 mm high and 487 mm deep. The S8 MaxV Ultra base measures 409 x 470 x 419 mm, with different space distribution but similar footprint.
Real-World Usage Experience
For homes with pets, the best robot vacuum depends on priorities. The Qrevo Edge S5A offers the highest suction power and DuoDivide anti-tangle brush, ideal for abundant hair. The S8 MaxV Ultra adds visual pet recognition, useful for avoiding them during cleaning.
In large houses, the 180 minutes of autonomy are sufficient in all three cases. The difference will come from cleaning efficiency: the Qrevo Edge S5A with its superior power can complete the job more quickly.
For hard floors and parquet, the hot water washing of the Qrevo Edge S5A makes a difference compared to the cold water of the Qrevo S5V. The S8 MaxV Ultra with its vibrating mop and water at 60°C offers excellent results on these types of surfaces.
Maintenance convenience favours the Qrevo Edge S5A thanks to its tray self-cleaning 2.0, reducing the frequency of manual base cleaning. The detergent tank of the S8 MaxV Ultra provides convenience by dispensing product automatically.
Conclusion: Which to Choose?
Choose the Roborock Qrevo Edge S5A if you're looking for maximum suction power and the best automatic base maintenance system. Its 18,500 Pa, mop washing at 75°C and tray self-cleaning 2.0 make it the most complete option for those who don't want to worry about maintenance. Ideal for homes with carpets, pets with lots of hair and users who value raw power.
Choose the Roborock Qrevo S5V if you prefer a balanced model with reduced height. Its 96.5 mm allows it to access under more furniture than the other two. Although it lacks some advanced functions such as hot water for mop washing or dirt detection, it maintains the essentials: extendable rotating mops, hot air drying and DuoDivide anti-tangle brush. Perfect for homes without thick carpets where robot height is a priority.
Choose the Roborock S8 MaxV Ultra if you value artificial intelligence and advanced navigation functions. Its dual camera, recognition of 73 obstacles, pet detection and remote camera access place it in another technological category. The 20 mm brush and mop lift, together with the integrated detergent tank, provide versatility. Recommended for homes with pets where visual recognition is valued, tech-savvy users who will take advantage of the remote camera and homes with a combination of hard floors and thick carpets.
