Introduction
Roborock continues to dominate the premium robot vacuum market with three compelling options that showcase the brand's evolution in cleaning technology. The Roborock Qrevo Curv 2 Pro and Roborock Saros 10R represent the 2025 generation, whilst the Roborock S8 MaxV Ultra remains a strong contender from 2024. Each model brings something different to the table, making this comparison particularly useful for anyone trying to navigate Roborock's high-end lineup.
The Qrevo Curv 2 Pro stands out with exceptional suction power and a remarkably low profile. The S8 MaxV Ultra, despite being a year older, maintains relevance with its proven track record and specific design choices. The Saros 10R introduces warm water mopping and refined navigation technology. All three feature multifunctional bases with automatic maintenance capabilities, positioning them firmly in the premium segment for larger homes or those seeking minimal intervention.
Suction Power and Brushing Systems
The suction power hierarchy here is clear-cut. The Qrevo Curv 2 Pro dominates with 25,000 Pa—more than double what the S8 MaxV Ultra offers and noticeably stronger than the Saros 10R's 18,500 Pa. In practice, this translates to better performance on carpets and more effective deep cleaning on hard floors, particularly where embedded dirt or pet hair accumulates.
Both the Qrevo Curv 2 Pro and Saros 10R utilise Roborock's DuoDivide Anti-Tangle brush system, which channels hair towards the central suction point to minimise tangling. The S8 MaxV Ultra employs a dual rubber brush configuration. All three models feature elevating main brushes that lift during mopping to prevent cross-contamination.
The side brush configuration reveals interesting distinctions. Whilst all three extend outwards to reach corners more effectively, only the Qrevo Curv 2 Pro and Saros 10R include anti-tangle side brushes. The Saros 10R goes further by incorporating a side brush that elevates during mopping—a feature absent on both competitors. This matters when mopping near skirting boards, as it prevents the side brush from flicking dirty water around.
Mopping Performance
The mopping systems diverge considerably. The S8 MaxV Ultra relies on a single vibratory mop pad that scrubs at high frequency, supplemented by a small lateral extension for edges. The Qrevo Curv 2 Pro and Saros 10R instead use dual rotating mops with full extension capabilities for better edge coverage.
Mop elevation varies meaningfully. The S8 MaxV Ultra lifts its mop 20 mm when encountering carpets. The Qrevo Curv 2 Pro offers 7-17 mm elevation, whilst the Saros 10R provides the widest range at 12-22 mm. For homes with thick rugs or high-pile carpets, these differences affect how reliably the robot can transition between floor types without wetting textiles.
The Saros 10R introduces warm water mopping directly onto floors—neither competitor offers this. Warm water naturally improves cleaning efficacy on greasy marks or sticky residues. At the base level, all three wash mops with hot water and dry them using heated air to prevent odours. The Qrevo Curv 2 Pro features the latest 3.0 version of base tray self-cleaning, the Saros 10R has version 2.0, and the S8 MaxV Ultra lacks this function entirely, requiring occasional manual cleaning of the wash tray.
Both 2025 models automatically remove their mops at the base when switching to vacuum-only mode. The S8 MaxV Ultra doesn't have this capability, meaning the mop remains attached even during dry vacuuming sessions. All three detect dirty mops and soiled floors, adjusting their cleaning patterns accordingly.
Navigation Systems
Navigation technology shows clear generational progression. The Saros 10R employs StarSight 2.0, Roborock's newest system. The Qrevo Curv 2 Pro uses a retractable LiDAR unit that lowers the overall height, whilst the S8 MaxV Ultra features a traditional LiDAR turret—explaining its taller profile.
All three incorporate dual AI cameras, 3D laser sensors, and LED lighting for night-time navigation. They recognise pets and provide remote camera access through the app. Where they differ is obstacle recognition breadth: the Qrevo Curv 2 Pro identifies 200 different objects, the Saros 10R recognises 108, and the S8 MaxV Ultra handles 73. This affects how reliably each robot navigates cluttered spaces without intervention.
Each model runs SmartPlan AI for intelligent cleaning routines and spot recognition, though the specific CPU details for the Qrevo Curv 2 Pro weren't available. The other two operate on RR Mason 11.0 algorithms.
Battery Life and Coverage
Battery capacity sits at 6,400 mAh for both the Qrevo Curv 2 Pro and Saros 10R, compared to 5,200 mAh in the S8 MaxV Ultra. Despite this, runtime figures tell a different story. The Qrevo Curv 2 Pro achieves 290 minutes of operation—substantially longer than the 180 minutes offered by the other two models. This extended runtime likely stems from efficiency improvements rather than just battery size.
For larger properties, the Qrevo Curv 2 Pro's stamina means fewer mid-clean recharging sessions. The difference becomes particularly noticeable in homes exceeding 150 square metres, where the S8 MaxV Ultra and Saros 10R might need to return to base mid-cycle.
Smart Features
Obstacle climbing capabilities vary meaningfully. The Qrevo Curv 2 Pro and Saros 10R can traverse simple steps—useful for minor thresholds or sunken living areas. The S8 MaxV Ultra manages 20 mm obstacles, which covers most standard door thresholds but won't handle actual steps.
All three include Roborock's own voice assistant alongside compatibility with Alexa and Google Home. None feature robotic arms for object manipulation—a technology still rare even in premium segments.
Multifunctional Base Station
Each model includes a comprehensive base station handling automatic dust emptying, mop washing with hot water, and heated air drying. Dust bags hold 2.5 litres across all three. Clean water tanks uniformly offer 4 litres, whilst dirty water capacity sits at 3 litres for the 2025 models and 3.5 litres for the S8 MaxV Ultra.
The detergent situation differs. The S8 MaxV Ultra and Saros 10R incorporate dedicated detergent dispensers that automatically add cleaning solution during mop washing. The Qrevo Curv 2 Pro omits this, requiring manual addition of detergent to the clean water tank if desired.
As mentioned, the Qrevo Curv 2 Pro's 3.0 base tray self-cleaning represents the most advanced iteration, followed by the Saros 10R's 2.0 version. The S8 MaxV Ultra requires periodic manual cleaning of the wash basin. None offer UV disinfection or integrated plumbing connections, though no optional kits are available either.
Physical Dimensions
Height makes a dramatic difference here. The Qrevo Curv 2 Pro and Saros 10R stand just 79.8 mm tall—low enough to slip beneath most furniture, including many sofas and bed frames. The S8 MaxV Ultra's 103 mm height restricts access under lower-clearance furniture. This seemingly small difference has real implications for cleaning coverage, as areas beneath furniture often accumulate dust that taller robots simply can't reach.
Diameter remains virtually identical across all three at roughly 352-353 mm. Weight wasn't specified, though the slimmer profile robots likely carry similar mass given their larger batteries.
Base station footprints vary more than expected. The Saros 10R measures 381 mm wide, 488 mm tall, and 475 mm deep. The S8 MaxV Ultra sits at 409 mm wide, 470 mm tall, and 419 mm deep. The Qrevo Curv 2 Pro is the bulkiest at 450 mm in all dimensions—essentially a 45 cm cube. Consider available floor space carefully, as these aren't discreet charging docks.
Real-World Usage Scenarios
For larger homes, the Qrevo Curv 2 Pro's combination of 290-minute runtime and powerful 25,000 Pa suction makes it particularly capable. Its low profile ensures comprehensive coverage under furniture, though the lack of detergent dispensing means slightly more manual intervention. The substantial base station requires adequate floor space.
Pet owners will appreciate the anti-tangle brushes on both the Qrevo Curv 2 Pro and Saros 10R, paired with their strong suction. The S8 MaxV Ultra's dual rubber brushes also resist tangling, though its lower suction might struggle with deeply embedded pet hair in carpets.
Homes with varied flooring benefit from the Saros 10R's warm water mopping and comprehensive obstacle climbing. Its elevating side brush prevents water splashing during mopping near walls. The detergent dispenser and automatic mop removal reduce maintenance tasks.
The S8 MaxV Ultra suits those prioritising proven reliability over cutting-edge specifications. Its taller profile limits furniture access, and the lack of automatic mop removal or base tray self-cleaning means more hands-on maintenance. The vibratory mopping system works well on hard floors, though edge coverage isn't as thorough as the dual rotating mop competitors.
Conclusion: Which Should You Choose?
Choose the Roborock Qrevo Curv 2 Pro if you need maximum suction power and exceptional runtime for large properties. The 79.8 mm height makes it ideal if you want thorough cleaning under furniture. The 290-minute battery life means it can handle extensive floor plans in a single session. Accept that you'll need to add detergent manually and allocate space for the substantial base station.
Choose the Roborock S8 MaxV Ultra if you prefer a proven 2024 model with established reliability and don't mind slightly more manual involvement. It works well for smaller homes where the 180-minute runtime suffices. Be aware of the 103 mm height limiting access under low furniture, and plan for periodic base tray cleaning. The vibratory mopping system delivers solid results on hard floors.
Choose the Roborock Saros 10R if you want the most balanced 2025 option with warm water mopping, automatic detergent dispensing, and the most versatile obstacle management. The elevating side brush improves mopping near walls, whilst the low 79.8 mm profile ensures furniture access. It suits households wanting minimal intervention with comprehensive cleaning across different floor types and levels. The 18,500 Pa suction sits between the other two, offering strong performance without the Qrevo Curv 2 Pro's premium power.
