Roborock Qrevo S vs iRobot Roomba Combo j9+ Auto-Fill Robot Vacuum and Mop
When comparing the Roborock Qrevo S and the iRobot Roomba Combo j9+ Auto-Fill Robot Vacuum and Mop, the Roborock Qrevo S takes the lead with its impressive 7000Pa suction. In real-world use, this means deeper cleaning power that can tackle stubborn dirt and pet hair better than the Roomba's unspecified suction strength. While the Roborock Qrevo S comes with a smaller onboard water tank of 80mL, it compensates with a high-end multifunctional dock that handles multiple tasks. The iRobot Roomba Combo j9+ Auto-Fill's Clean Base Auto-Fill Dock offers a larger 210mL water tank, helping it maintain cleaning for longer without constant refills, but its mop pad requires manual washing. So, if you want serious suction power, go for the Roborock Qrevo S, but if you prefer automation and less maintenance, the Roomba might suit you better. Key specs: Weight: 132.98 oz vs 143.92 oz and Battery: 5200mAh vs 4460mAh.
Why compare these? The Roborock Qrevo S (high-end) and iRobot Roomba Combo j9+ Auto-Fill Robot Vacuum and Mop (mid-range) represent different approaches to robot vacuums. While they may appeal to different budgets, many buyers consider both options. This 2026 comparison helps you decide if the differences justify the price gap.
