Another very practical point, the base of the circular charger that allows to put it vertically in either direction, the connection is done without problem.
Only problem, the attachment of the dust compartment system is broken (wear?) After 6 months.
Fortunately, Amazon has been exemplary as usual and sent me another one immediately.
I could have even choose to get a refund.
What I will do if ever the same problem were to recur, while posting here again.
