How it compares
The Roborock S8 MaxV Ultra at ~$999 includes a full auto-base station that washes and dries mop pads — the j9+ dock does not. The Dreame X40 Ultra at ~$1,199 delivers 12,000Pa confirmed suction vs the j9+'s undisclosed figure, and its dock washes mop pads with 158°F water.
Limitations
- Mop dock does not wash or dry mop pads — manual cleaning required
- Suction Pa figure not disclosed by iRobot
- Camera navigation requires ambient light to function
- Cannot run in mop-only mode — must also vacuum
- Large dock footprint compared to some competitors
