The Qrevo Curv brings nearly double the suction power and longer battery range, making it the stronger choice for larger homes with mixed flooring. The S8 MaxV Ultra counters with superior mopping technology and automatic detergent dispensing at a significantly lower price point, perfect for homes prioritizing hard floor maintenance.
Roborock's premium lineup creates an interesting dilemma for buyers. The Qrevo Curv pushes boundaries with massive 18,500 Pa suction and extended battery life, positioning itself as the powerhouse option. The S8 MaxV Ultra takes a different approach, combining sophisticated mopping with smart automation features at a more accessible price. Both deliver premium experiences, but they excel in distinctly different areas that matter for different households.
Roborock Qrevo Curv
out of 10Roborock S8 MaxV Ultra
These two earn nearly identical ratings across the board, with the Qrevo Curv edging ahead by just 0.1 points overall (8.6 vs 8.5). They tie perfectly on value and features at 8.6 and 9.5 respectively. The Qrevo Curv takes small leads in cleaning (7.7 vs 7.5) and navigation (7.9 vs 7.8), but these tiny differences mean both deliver premium performance.
Suction power creates the biggest performance gap here. The Qrevo Curv's 18,500 Pa nearly doubles the S8 MaxV Ultra's 10,000 Pa, translating to noticeably better deep carpet cleaning and pet hair pickup. But the S8 MaxV Ultra's vibrating mop pad with 4,000 vibrations per minute plus its rotating edge mop provides more thorough hard floor cleaning than the Qrevo Curv's dual spinning pads at 200 RPM. Battery capacity also separates them significantly - the Qrevo Curv covers 4,305 square feet per charge compared to 3,229 for the S8 MaxV Ultra, making it better suited for larger homes.
The Qrevo Curv dominates with 18,500 Pa suction versus 10,000 Pa, plus its dual rubber and bristle brushes tackle different debris types better than the S8 MaxV Ultra's rubber-only design.
The S8 MaxV Ultra's vibrating pad at 4,000 vibrations per minute combined with its rotating edge mop outperforms the Qrevo Curv's 200 RPM dual spinning pads for scrubbing action.
With nearly double the suction power and a slightly larger dust bag (2.7L vs 2.5L), the Qrevo Curv handles pet hair more effectively.
The Qrevo Curv can climb obstacles up to 40mm high versus 20mm for the S8 MaxV Ultra, giving it better navigation over thresholds and transitions.
The S8 MaxV Ultra includes automatic detergent dispensing for cleaner mop pads, a convenience feature the Qrevo Curv lacks.
The Qrevo Curv's 6,400 mAh battery covers 4,305 square feet per charge, significantly outpacing the S8 MaxV Ultra's 3,229 square feet coverage.
Both support identical smart features including built-in voice control plus Amazon, Google, and Apple integration.

Both deliver premium robot vacuum experiences with subtle but important differences. The Qrevo Curv justifies its higher price for homes needing maximum suction and coverage. The S8 MaxV Ultra offers better value for hard floor focused homes. Either choice gets you top-tier automation and navigation.
