in a second configuration, the fastening element mechanically connects the at least one vacuuming-off unit directly to the adapter unit and the electrical contact point electrically connects the at least one vacuuming-off unit directly to the adapter unit such that energy is supplied to the at least one vacuuming-off unit from the external energy supply through the adapter unit in a second operating state,

the adapter unit has at least one fastening, and

in a third configuration with the adapter unit mechanically and electrically connected to the at least one vacuuming-off device such that energy is supplied to the at least one vacuuming-off unit from the external energy supply through the adapter unit in a third operating state, the at least one fastening mechanically connects the at least one vacuuming-off unit to a further hand-held power tool through the adapter unit.

2. The vacuuming-off system according to claim 1 , wherein the at least one connecting unit is configured to connect to at least one battery.

3. The vacuuming-off system according to claim 1 , wherein the adapter unit has at least one actuating element configured to activate and/or deactivate the at least one vacuuming-off unit.

4. The vacuuming-off system according to claim 1 , wherein the adapter unit has at least one handle.

5. The vacuuming-off system according to claim 1 , further comprising at least one vacuuming-off nozzle configured to be placed on and/or attached to the at least one vacuuming-off unit.

6. The vacuuming-off system according to claim 1 , wherein the adapter unit has at least one sensor unit that is configured, in the second configuration, to identify at least one activation state of the further hand-held power tool.

7. The vacuuming-off system according to claim 6 , wherein the adapter unit is configured, in the second configuration, to activate and/or deactivate the at least one vacuuming-off unit in dependence on the identified at least one activation state.

8. The vacuuming-off system according to claim 1 , wherein the hand-held power tool is configured as a hammer drill and/or a chipping hammer.

9. The vacuuming-off system according to claim 1 , wherein:

the fastening element is a latching element.

10. An adapter unit for a vacuuming-off device, comprising:

a single, contiguous body configured to removably directly electrically connect the adapter unit to an electrical contact point of a vacuuming-off unit interface and removably directly mechanically connect the adapter unit to a fastening element of the vacuuming-off unit interface, the vacuuming-off unit interface configured for removable mechanical and electrical connection to a hand-held power tool;

at least one connecting unit configured to connect to at least one external energy supply so as to provide energy to the vacuuming-off unit in a first operational configuration; and

at least one fastening configured to mechanically connect the adapter unit to a further hand-held power tool while the adapter unit is removably directly electrically connected to the electrical contact point of the vacuuming-off unit interface and removably directly mechanically connected to the fastening element of the vacuuming-off unit interface.

11. A system, comprising:

a first hand-held power tool;

a further hand-held power tool configured differently from the first hand-held power tool;

an external energy supply;

a vacuuming-off device, including at least one vacuuming-off unit having at least one interface, the at least one interface including a fastening element and an electrical contact point; and

an adapter unit having at least one connecting unit configured to connect to the external energy supply, wherein:

in a first configuration with the adapter unit removed from the vacuuming-off device and the vacuuming-off device mechanically connected to the first hand-held power tool, the fastening element mechanically connects the vacuuming-off unit directly to the first hand-held power tool, the electrical contact point electrically connects the vacuuming-off unit directly to the first hand-held power tool, and the first hand-held power tool is mechanically connected with the external energy supply such that in a first operational state energy from the external energy supply is supplied to the vacuuming-off unit through the first hand-held power tool, and

in a second configuration, with the vacuuming-off device mechanically connected to the further hand-held power tool, the fastening element mechanically connects the vacuuming-off unit directly to the adapter unit, the electrical contact point electrically connects the vacuuming-off unit directly to the adapter unit, and the adapter is mechanically and electrically connected to the external energy supply such that in a second operational state energy from the external energy supply is supplied to the vacuuming-off unit through the adapter unit.

12. The system according to claim 11 , wherein the first hand-held power tool is configured as a hammer drill and/or a chipping hammer.
