1. An external communication apparatus as part of a vacuum cleaner, the external communication apparatus comprising:
a communication interface for wirelessly communicating with an external electric device,
wherein the vacuum cleaner is actuatable by the external electric device,
wherein the external electric device is one of a machine tool or an energy storage module for an electric power supply of a machine tool,
wherein the external communication apparatus and the external electric device form a system,
wherein the energy storage module has a module housing with a device interface for a detachable connection to the machine tool,
wherein the machine tool has a drive motor to drive a tool holder on which a tool provided to process a workpiece is arranged or is arrangeable, the drive motor being switchable using a switching element of the machine tool and/or the energy storage module,
wherein the communication interface of the external communication apparatus is designed for wireless communication with a wireless communication interface of the external electric device and is designed to receive at least one control command to switch on and/or switch off the vacuum cleaner as a function of a switching status of the switching element from the wireless communication interface of the external electric device via a wireless control connection, and
wherein the communication interface of the external communication apparatus is designed to receive at least one registration message from the wireless communication interface of the external electric device to establish the wireless control connection, and
wherein the external communication apparatus is ready in a standby mode to receive the at least one registration message and the external communication apparatus is not ready in an operating mode to receive the at least one registration message, and
wherein the external communication apparatus is designed in the standby mode to send at least one request message to request the external electric device to send the at least one registration message to the external communication apparatus.
