No, there’s no need to pay extra.
The X11 package includes 1 filter baskets and 1 standard charging adapter.
If you like fast charging,
you need to buy an additional fast charging adapter,
which can fully charge the robot within 1.5 hours for 3.5-hour runtime.
I am missing 1 x Standard Fine Filter Basket,
2 x Replacement Screw (M4 x 40)
2 x Replacement Cap Nut (M4)
from my just opened box.
Please send as soon as possible.
