iRobot Roomba Combo j9+ Auto-Fill Robot Vacuum and Mop vs Shark PowerDetect NeverTouch Pro 2-in-1 Robot Vacuum & Mop

The iRobot Roomba Combo j9+ Auto-Fill Robot Vacuum and Mop is a mid-range option that excels with its Clean Base Auto-Fill Dock, automating both dust emptying and water refilling. In real-world testing, the Shark PowerDetect NeverTouch Pro 2-in-1 Robot Vacuum & Mop stands out with its NeverTouch Pro Base, offering true hands-free maintenance by washing and drying the mop pad after each use. With a runtime of 120 minutes for the iRobot versus 110 minutes for the Shark, you'll get a bit more cleaning time with the Roomba.
