Cleaning Performance
The Saros 10R’s 22,000Pa suction is 2.2x the S8 MaxV Ultra’s 10,000Pa. On carpet, this translates to meaningfully better embedded dirt extraction — the 10R pulls more sand and debris from medium and thick pile. The S8 MaxV Ultra scored 96.4% debris removal by weight in lab testing, strong for its generation, but newer motors have moved the benchmark.
The S8 MaxV Ultra’s VibraRise 3.0 vibrating pads scrub at 4,000 times per minute with a 20mm mop lift — the highest lift in this comparison, keeping pads fully off carpet during vacuuming. The Saros 10R uses a vibrating pad without the same aggressive scrubbing action but has a FlexiArm side brush for edge sweeping during vacuuming.
Both robots mop competently. The S8 MaxV Ultra scrubs harder on flat surfaces; the Saros 10R sweeps edges better during vacuuming.
Winner: Roborock Saros 10R — 2.2x the suction is the most impactful difference. The S8 MaxV Ultra’s vibrating mop is excellent but can’t compensate for the suction gap on carpet.
Navigation & Obstacle Avoidance
The S8 MaxV Ultra uses LiDAR, 3D structured light, and an RGB camera with Reactive AI 2.0. The proven RGB camera system identifies specific objects — shoes, cables, pet waste — and enables video monitoring. It’s one of the most refined camera-based navigation systems available.
The Saros 10R uses LiDAR and a camera with a retractable LiDAR turret that lowers for under-furniture navigation. Its camera system is capable but the S8 MaxV Ultra’s Reactive AI 2.0 has more refined object classification from more firmware iterations.
Both robots navigate accurately and map homes reliably. The S8 MaxV Ultra’s edge in obstacle avoidance comes from its mature, well-tested AI system and explicit pet waste detection.
Winner: Roborock S8 MaxV Ultra — More refined camera AI and proven pet waste avoidance. The margin is modest, but the S8 MaxV Ultra’s Reactive AI 2.0 is well-proven.
Dock & Maintenance
The S8 MaxV Ultra’s 8-in-1 RockDock offers hot water mop washing, hot-air drying, auto-empty, auto water refill, and auto detergent dispensing. The optional Refill & Drainage System connects to home plumbing, eliminating water tank management entirely. The auto detergent adds cleaning solution to every mop wash without manual intervention.
The Saros 10R’s dock provides hot water mop washing, auto-empty, and self-clean. Solid premium features, but no auto detergent and no plumbed option.
The S8 MaxV Ultra’s dock is the clear winner — auto detergent and plumbed water represent tangible convenience upgrades.
Winner: Roborock S8 MaxV Ultra — Auto detergent and optional plumbed system make the dock meaningfully more hands-free.
Battery & Runtime
Both robots run 180 minutes per charge. Identical battery life with no advantage for either side.
Winner: Tie — Same 180-minute runtime.
Value & Price
The S8 MaxV Ultra at $899-1,799 (typically $949) costs $350 less than the Saros 10R at $999-1,599 (typically $1,299).
The Saros 10R’s $350 premium buys 2.2x the suction, a slimmer profile (3.8 vs 4.06 inches), retractable LiDAR, and FlexiArm side brush sweeping. These are meaningful cleaning upgrades.
The S8 MaxV Ultra’s lower price comes with a more feature-rich dock (auto detergent, plumbed option), a more refined camera system, and 20mm mop lift. Its weaknesses — lower suction, taller profile — reflect its older generation.
For buyers who prioritize cleaning power and under-furniture reach, the Saros 10R justifies the $350 premium. For buyers who want the most automated, hands-free dock experience with proven camera navigation, the S8 MaxV Ultra at $350 less is compelling.
The Saros 10R wins overall because 2.2x suction is a fundamental cleaning advantage that matters every cleaning cycle, while dock features are incremental conveniences.
Winner: Roborock Saros 10R — 2.2x suction justifies $350 more. The S8 MaxV Ultra’s dock features are excellent but the 10R simply cleans harder.

Frequently Asked Questions
Is the Saros 10R worth $350 more than the S8 MaxV Ultra?
If carpet cleaning is your priority, yes. The 10R's 22,000Pa suction is 2.2x the S8 MaxV Ultra's 10,000Pa, delivering substantially better embedded dirt extraction. If you care more about the RGB camera, auto detergent, or plumbed water, the S8 MaxV Ultra offers features the 10R lacks.
Which robot has better obstacle avoidance?
Both use LiDAR and a camera. The S8 MaxV Ultra's Reactive AI 2.0 with RGB camera is more proven, with better object classification and pet waste avoidance. The Saros 10R's camera system is capable but the S8 MaxV Ultra's AI processing is more refined for obstacle scenarios.
Which dock is better?
The S8 MaxV Ultra's 8-in-1 RockDock with auto detergent and optional plumbed water system is more feature-rich. The Saros 10R's dock offers hot water wash which the S8 MaxV Ultra also has, plus self-clean. Both are premium — the S8 MaxV Ultra wins on convenience features.
Which robot fits under furniture better?
The Saros 10R at 3.8 inches is notably slimmer than the S8 MaxV Ultra at 4.06 inches. The 10R's retractable LiDAR turret can further reduce its effective height. For under-furniture reach, the 10R has the advantage.
