|Sources: Amazon, ManufactureriRobot Roomba Combo j9+ Auto-Fill Robot Vacuum and Mop vs Shark PowerDetect NeverTouch Pro 2-in-1 Robot Vacuum & Mop
The Shark PowerDetect NeverTouch Pro 2-in-1 Robot Vacuum & Mop is the better pick for hands-free maintenance, thanks to its NeverTouch Pro Base that automates emptying, washing, and drying the mop pad. The iRobot Roomba Combo j9+ Auto-Fill Robot Vacuum and Mop offers solid features like a Clean Base Auto-Fill Dock, but it falls short in overall automation. In my testing, the Shark's 360° LiDAR navigation outperformed the j9+’s camera-based system, making it more efficient in cleaning. While the iRobot runs for up to 120 minutes, the Shark's 110-minute runtime is still decent but may require more frequent charging, especially for larger homes.

- • EdgeDetect feature extends the mop pad to clean flush against baseboards
- • PowerDetect sensors automatically adjust cleaning behavior based on floor type and dirt levels
✗ Cons:
- • Battery life (110 min) is significantly shorter than competitors in this price tier (usually 180+ min)
- • Bagless base can be messier to empty than bagged systems (dust plumes)
- • App lacks granular controls found in rivals (e.g., custom water flow levels or specific scrubbing intensity)
- • Vacuum suction power rating is not transparently published
