Abstract

The present invention relates to an autonomously operable vacuum cleaner that has a modular design. The vacuum cleaner in this respect comprises a cleaning head module as well as a separate canister module. The cleaning head module and the canister module are in this respect connected to one another via a hose so that dust sucked in via the cleaning head module can be conveyed into the canister module.

Claims

1. An autonomously operable vacuum cleaner, comprising

a cleaning head module;

a canister module having rechargeable batteries that is separate from the cleaning head module and comprises a control that carries out a navigation function to provide an autonomous control of the vacuum cleaner; and

a hose that fluidically and electrically connects the cleaning head module to the canister module, wherein both the cleaning head module and the canister module each have a drive mechanism that provides independent mobility to the respective modules; and

wherein the canister module or the cleaning head module comprises a motor fan unit by which a vacuum is made possible to suck air into the canister module via the cleaning head module,

and wherein a connection of the cleaning head module to the hose or the connection of the hose to the canister module is configured as releasable,

and further wherein

i) the cleaning head module is releasable from the hose connected to the canister module having a motor fan unit and is replaceable with a driveless cleaning head to be operated by a user or with a cleaning tool or

the hose is releasable from the canister module having a motor fan unit together with the cleaning head module and is replaceable with a further hose to which a driveless cleaning head to be operated by a user or a cleaning tool, is attached;

or

ii) a suction pipe to be operated by the user is inserted between the hose and the cleaning head module and the cleaning head module is operable by the user by means of the suction pipe,

wherein, in the event of replacement of the cleaning head module, the control of the vacuum cleaner carrying out the navigation function is deactivatable by a user and the drive function is capable of being set to idle or brought into an operating mode in which the control carrying out the navigation function allows the canister module to follow the user.

2. The autonomously operable vacuum cleaner in accordance with claim 1, wherein that the releasable connection of the cleaning head module to the hose or the connection of the hose to the canister module is configured as a plug-in connection, as a plug-in connection with a snap-in connection or as a screw connection.

3. The autonomously operable vacuum cleaner in accordance with claim 1, wherein the canister module provides power or control signals to the cleaning head module via at least one electric line that is integrated in or extends in parallel with the hose.

4. The autonomously operable vacuum cleaner in accordance with claim 3, wherein the at least one electric line is configured as releasable.

5. The autonomously operable vacuum cleaner in accordance with claim 4, wherein a plug-in connection of each electric line comprises

a socket at the canister module and a plug connectable to the socket of the canister module at the hose and a socket at the cleaning head module and a further plug connectable to the socket of the cleaning head module at the hose;

or

a socket at the hose and a plug connectable to the socket of the hose at the canister module and a socket at the cleaning head module and a plug connectable to the socket of the cleaning head module at the hose;

or

a socket at the hose and a plug connectable to the socket of the hose at the canister module and a further socket at the canister module and a plug connectable to the further socket of the hose at the cleaning head module;

or

a socket at the canister module and a plug connectable to the socket of the canister module at the hose and a socket at the hose and a plug connectable to the socket of the hose at the cleaning head module.

6. The autonomously operable vacuum cleaner in accordance with claim 1, wherein the control receives or processes sensor input data of at least one sensor for mapping a surrounding space.

7. The autonomously operable vacuum cleaner in accordance with claim 1, wherein the canister module comprises at least one unit for separating sucked in dust.

8. The autonomously operable vacuum cleaner in accordance with claim 1, wherein the cleaning head module or a driveless cleaning head has at least one cleaning brush.

9. The autonomously operable vacuum cleaner in accordance with claim 3, wherein the at least one electric line is configured as releasable between the canister module and the hose or between the hose and the cleaning head module.

10. The autonomously operable vacuum cleaner in accordance with claim 3, wherein the at least one electric line is configured as a plug-in connection between the canister module and the hose or between the hose and the cleaning head module.

11. The autonomously operable vacuum cleaner in accordance with claim 1, wherein the cleaning tool comprises a crevice tool, an upholstery tool or a furniture brush.

12. The autonomously operable vacuum cleaner in accordance with claim 6, wherein the at least one sensor comprises a camera sensor, a sonar sensor, a lidar sensor, an infrared sensor or a 3D scanner sensor.
