Pros & cons

- ✓Automatically refuses to mop carpet when the pad is on
- ✓Simple, stable app without the gimmick overload of Chinese rivals
- ✓Light 6.27 lb body and low 4.09 in profile fits under most furniture

- ✗iRobot publishes no runtime, suction, or bin specs whatsoever
- ✗No self-empty dock at this price tier
- ✗iRobot's ongoing financial troubles cloud long-term support
