Quick Verdict
The Dreame L50 Ultra is the better robot — 19,500Pa suction nearly doubles the S8 MaxV Ultra's 10,000Pa, ProLeap legs cross thresholds other robots can't, and it holds the #1 Vacuum Wars ranking. The S8 MaxV Ultra counters with an auto detergent dispenser, 20mm mop lift, optional plumbed drainage, and a lower street price ($899-949). The L50 Ultra is the performance pick; the S8 MaxV Ultra is the bargain-hunter's flagship.

Cleaning Performance
The L50 Ultra’s 19,500Pa suction is nearly double the S8 MaxV Ultra’s 10,000Pa — the single biggest spec gap in this comparison. On carpet, the difference is real and measurable: the L50 Ultra pulls significantly more embedded dirt and sand from medium and thick pile. The S8 MaxV Ultra’s 10,000Pa was competitive when it launched, but newer flagships have moved well past it.
On hard floors, the S8 MaxV Ultra still performs well, achieving 96.4% debris removal by weight in lab testing. Its VibraRise 3.0 mopping system delivers 4,000 scrubs per minute with vibrating pads — a different approach from the L50 Ultra’s spinning pads. The S8 MaxV Ultra also adds automatic detergent dispensing, which improves mopping stain removal versus water-only cleaning.
The L50 Ultra’s HyperStream DuoBrush handles hair up to 11.8 inches without tangling, and its Dual Flex Arm extends mop coverage to wall edges. The S8 MaxV Ultra’s 20mm mop auto-lift is among the highest in class, keeping wet pads well clear of carpet during vacuuming.
Winner: Dreame L50 Ultra — Nearly 2x the suction and the #1 overall Vacuum Wars ranking. The S8 MaxV Ultra’s vibrating mop and auto detergent are strong but can’t overcome the suction deficit.
Navigation & Obstacle Avoidance
Both robots use LiDAR + 3D structured light + RGB camera. The L50 Ultra recognizes 180+ object types using its advanced system. The S8 MaxV Ultra’s Reactive AI 2.0 is a capable system with video monitoring and pet detection, though it struggles with thin cables and shoelaces.
The L50 Ultra’s definitive advantage is ProLeap — retractable legs that physically lift the robot over thresholds up to 2.36 inches. Door tracks, raised carpet transitions, and floor-level obstacles that stop the S8 MaxV Ultra are non-issues for the L50 Ultra.
At 3.5 inches, the L50 Ultra is also slimmer than the S8 MaxV Ultra’s 4.06 inches, giving it access to tighter under-furniture spaces. Both create accurate multi-floor maps with full app control.
Winner: Dreame L50 Ultra — ProLeap obstacle crossing, more object types, and a slimmer profile. The S8 MaxV Ultra’s Reactive AI 2.0 is capable but not competitive with the L50’s newer system.
Dock & Maintenance
The S8 MaxV Ultra’s 8-in-1 RockDock Ultra is feature-packed: hot water mop wash, hot-air dry, auto-empty, auto water refill, and auto detergent dispenser. The optional Refill & Drainage System connects directly to your plumbing, eliminating manual water management entirely — a feature no Dreame dock offers.
The L50 Ultra’s AceClean DryBoard dock washes mops at 167°F with 4 temperature settings, dries with hot air, auto-empties (100 days), and auto-refills water. Its 20-nozzle mop cleaning system is thorough. However, it lacks auto detergent and has no plumbed option.
The S8 MaxV Ultra’s auto detergent is a genuine advantage for mopping hygiene. The plumbed drainage option makes it the only robot in this comparison that can operate for months without any manual water management. The L50 Ultra’s temperature control and nozzle count counter, but the S8 MaxV Ultra’s dock has more unique features.
Winner: Roborock S8 MaxV Ultra — Auto detergent dispenser and optional plumbed drainage give it dock features the L50 Ultra can’t match.
Battery & Runtime
Both robots run approximately 180 minutes. The L50 Ultra’s 6,400mAh battery achieves slightly better real-world efficiency, but the difference is negligible. Both comfortably clean homes up to 2,500 square feet on a single charge.
Winner: Tie — Virtually identical runtime and efficiency.
Value & Price
The S8 MaxV Ultra launched at $1,799 but now commonly sells for $899-949 — a steep discount from MSRP. The L50 Ultra typically sells for $1,099-1,199. At current street prices, the S8 MaxV Ultra costs $200-300 less.
The L50 Ultra’s premium buys nearly 2x the suction, ProLeap legs, better obstacle avoidance, and a slimmer profile. The S8 MaxV Ultra’s lower price, auto detergent, plumbed dock option, and 20mm mop lift make it a compelling alternative for buyers who prioritize mopping convenience and value.
For carpet-heavy homes, the L50 Ultra’s suction advantage is worth the extra $200-300. For hard-floor homes where mopping matters most, the S8 MaxV Ultra at $899 with auto detergent is arguably the smarter buy.
Winner: Roborock S8 MaxV Ultra — At $899-949, it’s a previous-gen flagship with unique dock features at a significant discount. The L50 Ultra is better but costs more.

Frequently Asked Questions
How does the S8 MaxV Ultra's suction compare to the L50 Ultra in real cleaning?
The gap is significant. The L50 Ultra's 19,500Pa extracts nearly twice the embedded dirt from carpet compared to the S8 MaxV Ultra's 10,000Pa. In lab testing, the S8 MaxV Ultra still achieves 96.4% debris removal by weight on hard floors, but carpet deep-cleaning is where the suction difference shows clearly.
What is the Roborock Refill & Drainage System?
The S8 MaxV Ultra offers an optional plumbed setup that connects the dock directly to your home's water supply and drain. This eliminates the need to manually refill clean water or empty dirty water — true zero-maintenance operation. The L50 Ultra's dock requires manual water tank refills every 1-2 weeks.
Is the S8 MaxV Ultra's auto detergent feature worth it?
Yes, for mopping performance. The auto detergent dispenser adds cleaning solution to every mop cycle automatically, improving stain removal versus water-only mopping. The L50 Ultra's dock does not auto-dispense detergent.
Which robot is better for homes with lots of carpet?
The Dreame L50 Ultra, without question. At 19,500Pa versus 10,000Pa, the suction gap is nearly 2x. The S8 MaxV Ultra's 20mm mop lift is helpful for keeping wet pads off carpet, but its vacuuming power on thick carpet is its weakest point.
