Roborock Q5 Pro+ Robot Vacuum and Mop vs iRobot Roomba Combo j9+ Auto-Fill Robot Vacuum and Mop
The Roborock Q5 Pro+ Robot Vacuum and Mop is the more powerful option, boasting a jaw-dropping 5,500 Pa suction. This means it can tackle dirt and pet hair with ease, making it great for homes with furry friends. On the flip side, the iRobot Roomba Combo j9+ Auto-Fill Robot Vacuum and Mop automates both dust emptying and water refilling, which is a game-changer for convenience in 2026. In my testing, the Roborock's 5200mAh battery gives you up to 240 minutes of runtime—plenty for larger homes. However, the iRobot’s auto-retract mopping system is designed to keep high-pile carpets dry, which is essential if you have mixed flooring. So, depending on your priorities, one may suit you better than the other. Key specs: Weight: 112.88 oz vs 143.92 oz and Battery: 5200mAh vs 4460mAh.
Why compare these? Both the Roborock Q5 Pro+ Robot Vacuum and Mop and iRobot Roomba Combo j9+ Auto-Fill Robot Vacuum and Mop are mid-range robot vacuums competing in the same market segment. This makes them direct rivals for buyers looking for mid-range features and performance in 2026. Understanding their differences helps you choose the right one for your specific needs.
