2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerRoborock Qrevo S vs Roborock S7 Max Ultra Robot Vacuum & Mop
The Roborock Qrevo S is the premium option here, boasting an impressive 7000Pa suction power that outperforms the 5500Pa of the Roborock S7 Max Ultra Robot Vacuum & Mop. In my testing, this makes a noticeable difference in picking up dirt and pet hair, especially on carpets. The Roborock S7 Max Ultra offers a larger onboard water tank at 200mL, which means fewer trips to the dock for refilling. For anyone who hates the hassle of constant maintenance, this is a significant advantage. Overall, if suction power is your primary concern, the Qrevo S crushes the competition, but for hands-off convenience, the S7 Max Ultra has its merits too.
