How do I send Keecker to the charging station?

Keecker is an autonomous robot but needs to be recharged.

There are four ways to send Keecker to his charging station:

with the voice command, tell Keecker,"Hey, Keecker, go to the charging station."
by clicking directly on the charging station location saved on the map (in Move > Map)
by clicking on the room in which the charging station is located (in Move>Send to) and then clicking on the charging station
Keecker automatically returns to its charging station when it has 5% battery (if you have updated your Keecker).

It is necessary to have your house mapped in order to benefit from these features.
