The Qrevo Curv takes the edge with nearly double the suction power and superior obstacle clearance, making it the stronger performer for challenging cleaning tasks. The S8 MaxV Ultra counters with automatic detergent dispensing and costs noticeably less, offering better value for those who prioritize mopping automation and budget-friendly pricing.
Two Roborock flagships go head-to-head here, each bringing serious cleaning muscle and automation to the table. The Qrevo Curv flexes its 18,500 Pa suction power and advanced navigation, targeting homes that need heavy-duty cleaning performance. The S8 MaxV Ultra approaches things differently, focusing on refined mopping features and dock convenience at a more accessible price point. Both deliver the premium experience Roborock is known for, but they excel in distinctly different ways.
Roborock Qrevo Curv
out of 10Roborock S8 MaxV Ultra
These two score neck-and-neck across the board, with the Qrevo Curv holding a slim 0.2-point advantage in overall rating (8.7 vs 8.5). That tiny gap shows up consistently in cleaning, navigation, and value categories too. But here's the kicker: they tie completely on features at 9.5 each. Translation? You're looking at two premium performers where personal priorities matter more than rating differences.
Suction power stands out immediately - the Qrevo Curv's 18,500 Pa nearly doubles the S8 MaxV Ultra's 10,000 Pa, giving it serious muscle for deep carpet cleaning and stubborn debris. Their mopping approaches differ too: the Qrevo Curv uses dual spinning pads that actively scrub floors, but the S8 MaxV Ultra brings vibrating pads at 4,000 RPM plus a rotating edge mop for thorough coverage. The S8 MaxV Ultra also adds automatic detergent dispensing to keep its mop pads cleaner during washing cycles. And for homes with high thresholds or thick rugs, the Qrevo Curv climbs obstacles up to 40mm compared to the S8 MaxV Ultra's 20mm limit.
The Qrevo Curv dominates with 18,500 Pa suction versus 10,000 Pa, plus it combines rubber and bristle brushes for versatile cleaning. Both use dual brush systems, but the Qrevo Curv's mixed brush design and higher suction give it the clear advantage.
The S8 MaxV Ultra edges ahead with its vibrating mop pads running at 4,000 RPM plus a dedicated edge spinning mop for complete coverage. It also carries more water onboard (100mL vs 80mL) and includes automatic detergent dispensing for cleaner mop maintenance.
Pet owners will appreciate the Qrevo Curv's massive suction advantage (18,500 Pa vs 10,000 Pa) for pulling embedded fur from carpets. Both offer similar dust bag capacities around 2.5-2.7L, but raw suction power makes the difference here.
Both use identical AI camera and 3D structured light technology, but the Qrevo Curv handles taller obstacles (40mm vs 20mm clearance). This extra height clearance helps it navigate over door thresholds and thick area rugs more reliably.
The S8 MaxV Ultra wins on dock features thanks to automatic detergent dispensing that keeps mop pads fresher. Dust bag capacities are nearly identical (2.7L vs 2.5L), so the detergent automation becomes the deciding factor.
The Qrevo Curv packs a larger 6,400 mAh battery compared to 5,200 mAh, translating to 4,305 square feet of coverage versus 3,229 square feet per charge. That's over 1,000 extra square feet of cleaning range.
Dead heat here - both support built-in voice commands plus Amazon Alexa, Google Assistant, and Apple integrations. You get identical smart home flexibility regardless of which model you choose.
