The unpre-released DE 10 2022 102 924.7 discloses a floor cleaning device, comprising a floor head and at least one cleaning roller, which rotates about an axis of rotation during operation of the floor cleaning device, the at least one cleaning roller being held on the floor head at least partially by a holding device, the holding device with the at least one cleaning roller being removable from the floor head is. Reference is made to this document in its entirety. Other floor cleaning devices are in the unpublished DE 10 2022 102 937.9 and DE 10 2022 102 918.2 disclosed, to which reference is made in full.

More floor cleaning devices are in the CN207850637 U and the WO 21248591 A1 disclosed.

The object of the invention is to provide a floor cleaning device of the type mentioned at the outset which, while being easy to operate, delivers an optimized cleaning result.

In the case of the floor cleaning appliance mentioned at the outset, this object is achieved according to the invention in that the rotary bearing device comprises a first rotary bearing which is arranged fixedly on the floor head and is positioned on the receiving shaft, in that the rotary bearing device has a second rotary bearing which is arranged on a cover for the receiving shaft wherein the cover can be moved relative to the floor head, and wherein during operation of the floor cleaning device the at least one cleaning roller is rotatably mounted on the first pivot bearing and the second pivot bearing as an abutment to the first pivot bearing, and that the at least one cleaning roller can be removed from the cover .

Due to the rotatory mounting of the at least one cleaning roller on the first pivot bearing and the second pivot bearing as an abutment, the cleaning roller can be provided with a relatively large length. This allows a relatively large area to be cleaned on a floor to be cleaned.

The at least one cleaning roller is positioned in the receiving shaft on the bottom head. This is closed by the cover and holds the at least one cleaning roller in position and also provides a corresponding pivot bearing via the second pivot bearing.

The receiving shaft can be opened by moving the cover to the bottom head and the at least one cleaning roller can be removed in a simple manner. The mobility of the cover to the base head, in order to be able to open the receiving shaft by moving the cover, can be realized by a movable arrangement (movable assembly) of the cover on the base head, and/or by a complete detachability (separation) of the cover from the floorhead. The movable mounting of the cover on the bottom head can be, for example, a pivot mounting and/or a displacement mounting.

In principle, it is also possible that the at least one cleaning roller can be removed when it is held on the cover. As a result, an operator does not have to touch them.

For example, the at least one cleaning roller can also be removed through the cover on the receiving shaft when the floor cleaning device is standing up at a floor station.

The detachability of the cleaning roller from the cover results in simplified cleaning of the cleaning roller itself. This can (after removing the lid) for example in a washing machine - be cleaned - without the lid.

The cover in the solution according to the invention is part of the floor head, which is movable relative to the floor head, and is not part of the at least one cleaning roller.

The solution according to the invention can be implemented on different machine types. It can be implemented on floor cleaning devices that have a blower device for sucking off a dirty fluid, in particular from the at least one cleaning roller. It can be implemented on floor cleaning devices that are fan-free. It can be implemented on floor cleaning devices which have a holding rod device for guiding the floor to be cleaned by a standing user. It can be implemented on a self-propelled and self-steering floor cleaning device (cleaning robot).

It is favorable if a removal direction of the at least one cleaning roller from the receiving shaft is at least approximately parallel to the axis of rotation. This results in easy removal and also easy insertion of the at least one cleaning roller on the receiving shaft with coupling to the pivot bearing device. Furthermore, a simple structural design of the bottom head results.

It is particularly advantageous if a receiving chamber for the dirty fluid tank, which is arranged on the floor head, is arranged next to the receiving shaft for the at least one cleaning roller in relation to a first width direction transverse to the axis of rotation. As a result, dirty fluid, which is detached from the at least one cleaning roller, can be coupled directly and in particular without a fan into the dirty fluid tank in the receiving chamber. The receiving chamber also makes it possible, for example, to remove the dirty fluid tank from the side of the floor head. This results in easy operability.

It is particularly advantageous if the dirty fluid tank can be removed from the receiving chamber in a removal direction which is at least approximately parallel to the axis of rotation. This results in easy detachability and also insertability of the dirty fluid tank on the floor head. For example, the dirty fluid tank can be pushed into or removed from the receiving chamber in the manner of a drawer. The dirty fluid tank can also be removed, for example, when the floor cleaning device is standing on a floor station.

• - die mindestens eine Reinigungswalze ist aus dem Aufnahmeschacht an einer lateralen ersten Seite des Bodenkopfs entnehmbar;
• - der Schmutzfluid-Tank ist aus der Aufnahmekammer an einer lateralen ersten Seite des Bodenkopfs entnehmbar;
• - der Schmutzfluid-Tank und die mindestens eine Reinigungswalze sind an dem Bodenkopf an der gleichen Seite entnehmbar, welche insbesondere eine laterale Seite ist;
• - der Schmutzfluid-Tank und die mindestens eine Reinigungswalze sind unabhängig voneinander an dem Bodenkopf entnehmbar und/oder an dem Bodenkopf einsetzbar;
• - eine Entnahmerichtung des Schmutzfluid-Tanks von dem Bodenkopf und eine Entnahmerichtung der mindestens einen Reinigungswalze von dem Bodenkopf sind parallel zueinander.

It is favorable if at least one of the following is provided:

• - The at least one cleaning roller can be removed from the receiving shaft on a lateral first side of the floor head;
• - The dirty fluid tank can be removed from the receiving chamber on a lateral first side of the floor head;
• - The dirty fluid tank and the at least one cleaning roller can be removed from the bottom head on the same side, which is in particular a lateral side;
• - The dirty fluid tank and the at least one cleaning roller can be removed from the floor head and/or used on the floor head independently of one another;
• - A removal direction of the dirty fluid tank from the floor head and a removal direction of the at least one cleaning roller from the floor head are parallel to each other.

If the at least one cleaning roller can be removed from the receiving shaft on a lateral first side of the base head, the at least one cleaning roller can be easily removed or inserted on the base head.

Correspondingly, the dirty fluid tank can also be easily inserted into or removed from the floor head.

If the dirty fluid tank and the at least one cleaning roller can be removed on the same side and, for example, can also be removed in parallel directions, a structurally favorable design results. The corresponding bottom head can be produced in a simple manner. If, for example, the floor cleaning device stands up on a floor station, the dirty fluid tank and the cleaning roller can then also be easily removed or inserted.

• - das Abtriebselement sitzt an dem Bodenkopf;
• - das Abtriebselement ist an dem ersten Drehlager positioniert;
• - das Abtriebselement bildet das erste Drehlager;
• - das Abtriebselement ist näher zu einer zweiten lateralen Seite des Bodenkopfs positioniert als zu einer lateralen ersten Seite, wobei die laterale erste Seite abgewandt zu der lateralen zweiten Seite ist und der Deckel an der lateralen ersten Seite positioniert ist und/oder über die laterale erste Seite die mindestens eine Reinigungswalze entnehmbar ist.

It is favorable if a torque transmission device is arranged on the floor head, which torque transmission device transmits a torque for the drive motor to the at least one cleaning roller, the torque transmission device comprising a driven element with at least one of the following:

• - The driven element sits on the bottom head;
• - The output element is positioned on the first pivot bearing;
• - The output element forms the first pivot bearing;
• - the driven element is positioned closer to a second lateral side of the bottom head than to a lateral first side, the lateral first side facing away from the lateral second side and the cover being positioned on the lateral first side and/or over the lateral first side, the at least one cleaning roller can be removed.

In this way, the at least one cleaning roller can be driven in its rotational movement in a simple manner. A compact construction of the floor head results. A relatively long cleaning roller can be used.

In a structurally simple embodiment, the second pivot bearing includes a roller bearing (such as a ball bearing) or a plain bearing. This allows an optimized abutment to be formed in a simple manner.

In particular, the cover can be moved to the floor head with separation from the at least one cleaning roller and/or the cover can be removed from the floor head with at least one cleaning roller held thereon. In particular, there is a corresponding option for an operator. If the cover with at least one cleaning roller held thereon can be removed from the bottom head, it can be removed, for example, without an operator having to touch a dirty cleaning roller directly.

In particular, it is provided that the cover is movably connected to the base head and/or can be removed from the base head. If the cover is movably connected to the base head, it is movably connected to the base head, for example via a pivot bearing and/or a displacement bearing. When detachable from the bottom head, the lid as a whole can be separated from the bottom head.

• - ein vorderes Ende des Bodenkopfs liegt an der mindestens einen Reinigungswalze;
• - die mindestens eine Reinigungswalze ragt an der Vorderseite über den Aufnahmeschacht hinaus;
• - der Aufnahmeschacht ist zu einer Aufstellebene des Bodenkopfs hin offen.

It is favorable if the receiving shaft for the at least one cleaning roller is open to a front side of the floor head, with at least one of the following:

• - A front end of the floor head is located at the at least one cleaning roller;
• - The at least one cleaning roller protrudes at the front beyond the receiving shaft;
• - The receiving shaft is open to an installation level of the floor head.

It can thereby achieve a near-edge cleaning. The at least one cleaning roller can be moved up to a lateral boundary of the floor to be cleaned and can still touch the lateral boundary.

In particular, the cover is fixed on a lateral side of the base head so that it can be removed from the base head. As a result, the receiving shaft can be closed or opened in a simple manner and the cleaning roller can be removed from the floor head in a simple manner or used on it. A cleaning roller can then, for example, be removed in a simple manner after a cleaning process in order to wash it in a washing machine, for example.

It is favorable if a fixing device is provided, by means of which the cover is detachably fixed to the base head, with the cover in particular being able to be removed from the base head as a whole. As a result, the abutment can also be connected to the base head via the cover in a simple manner, in order to enable the cleaning roller to be pivoted securely for cleaning operation.

• - die Fixierungseinrichtung umfasst eine Formschlussverbindung und/oder eine Kraftschlussverbindung (wie eine Magnetverbindung);
• - die Fixierungseinrichtung umfasst mindestens ein bewegliches Fixierungselement, welches über einen Bedienereingriff beweglich ist.

In a structurally favorable embodiment, at least one of the following is provided:

• - The fixing device comprises a form-fitting connection and/or a force-fitting connection (such as a magnetic connection);
• - The fixing device comprises at least one movable fixing element which can be moved by operator intervention.

In this way, the cover can be easily fixed to the bottom head and then removed.

It is favorable if (i) at least one pin is arranged on the cover and an associated recess for immersing the pin is arranged on the base head, and/or (ii) at least one pin is arranged on the base head and an associated one on the cover Recess is arranged for immersing the pin. The pin and the recess result in an additional fixation of the cover on the base head. In particular, a torque (due to the rotation of the cleaning roller on the rotary bearing device) can be absorbed and derived.

• - der mindestens eine Stift ist in einer Querrichtung versetzt zu der Rotationsachse positioniert;
• - der mindestens eine Stift weist eine Erstreckung auf
  1. (i) in einer Einsetzrichtung des Deckels an dem Bodenkopf; und/oder
  2. (ii) in einer Einsetzrichtung der mindestens einen Reinigungswalze an dem Aufnahmeschacht; und/oder
  3. (iii) parallel zu der Rotationsachse.

It is also favorable if at least one of the following is provided:

• - the at least one pin is positioned offset in a transverse direction to the axis of rotation;
• - The at least one pin has an extension
  1. (i) in an insertion direction of the lid on the bottom head; and or
  2. (ii) in a direction of insertion of the at least one cleaning roller on the receiving shaft; and or
  3. (iii) parallel to the axis of rotation.

In this way, it is relatively easy to derive torque for a removable cover when the floor cleaning machine is in operation. Furthermore, the cover can be easily inserted and removed from the bottom head.

It is favorable if the receiving chamber for the dirty fluid tank and the receiving shaft for the at least one cleaning roller are arranged directly one after the other in a first width direction, which is transverse to the axis of rotation. As a result, a flow path between the at least one cleaning roller and the receiving chamber with the dirty fluid tank and thus the dirty fluid tank is minimized. Dirty fluid detached from the at least one cleaning roller can thus be coupled directly into the dirty fluid tank in a simple manner and in particular without a fan.

It is particularly advantageous if a scraper device is provided, which sits on the floor head and sits, for example, on a hairpin device or the dirt fluid tank and wipes dirt fluid off the at least one cleaning roller during operation of the floor cleaning machine, and a mouth device is provided which the dirty fluid tank is arranged and on which during operation of the floor cleaning machine stripped dirty fluid is coupled fan-free into the dirty fluid tank. As a result, for example, the floor cleaning device according to the invention can be operated in an energy-saving manner.

It is also favorable if at least one sweeping element is provided, which acts on coarse dirt on a floor to be cleaned and makes this available to the at least one cleaning roller for entrainment. This results in an optimized cleaning result. The at least one sweeping element is arranged, for example, on the dirty fluid tank.

In particular, provision is made for the at least one cleaning roller to be held rotatably between the first pivot bearing and the second pivot bearing and to a certain extent to be held hanging between these two pivot bearings. This allows a relatively long cleaning roller to be used.

A cleaning liquid tank is provided, which supplies cleaning liquid to the at least one cleaning roller and/or a floor to be cleaned via a nozzle device. Dirt on the floor can be moistened and thus removed more easily via cleaning liquid, which is applied directly to the floor to be cleaned and/or is applied to the floor via a moistened cleaning roller.

• - der Reinigungsflüssigkeits-Tank ist an dem Bodenkopf oder an einer Haltestabeinrichtung positioniert;
• - es ist eine Zuführungseinrichtung für Reinigungsflüssigkeit vorgesehen, über welche Reinigungsflüssigkeit aus dem Reinigungsflüssigkeits-Tank zu der Düseneinrichtung strömt;
• - an dem Reinigungsflüssigkeits-Tank oder einer Zuführungseinrichtung für Reinigungsflüssigkeit zu der Düseneinrichtung ist ein Ventil und/oder eine Pumpe angeordnet.

It is particularly favorable if at least one of the following is provided:

• - the cleaning liquid tank is positioned on the floor head or on a support rod means;
• - A supply device for cleaning liquid is provided, via which cleaning liquid flows from the cleaning liquid tank to the nozzle device;
• - A valve and/or a pump is arranged on the cleaning liquid tank or on a supply device for cleaning liquid to the nozzle device.

This results in an optimized cleaning result.

It can be provided that the dirty fluid tank has a first area and a second area connected to the first area, the second area having a greater width in the second width direction than the first area, and that the second area between the drive motor and the at least one cleaning roller is positioned and the first area is positioned in front of a first end face of the drive motor in relation to the second width direction.

This solution results in an optimized use of space at the floor head. A dirt fluid tank can be provided which has a large capacity and can be “accommodated” on the floor head in a space-saving manner.

The second area results in an optimized coupling capability and in particular a fan-free coupling capability of dirty fluid from the at least one cleaning roller unit.

The second area follows the drive motor in relation to the first width direction and is thus positioned between the drive motor and the at least one cleaning roller. To a certain extent, it forms a finger which is immersed in an area between the drive motor and the at least one cleaning roller.

It is favorable if the first area follows the second area in the first width direction. This results in an optimized use of space with an optimized coupling possibility of dirty fluid.

It is particularly advantageous if an insertion direction of the dirty fluid tank is at least approximately parallel to the bottom head of the second width direction. This results in easy removal and also usability of the dirty fluid tank on the floor head for an operator. Furthermore, there is an optimized use of space.

It is also favorable if a torque transmission device is provided for torque transmission from the at least one drive motor to the at least one cleaning roller, which bridges a distance between the drive motor and the at least one cleaning roller in the first width direction and which is connected to the drive motor in the area of a second end face of the Drive motor is coupled effective torque, the second end face of the drive motor facing away from the first end face. This results in an optimized use of space. The at least one cleaning roller can be operated with optimized speeds and optimized torque.

• - A width of the second area in the second width direction is at least 1.5 times, in particular at least 2 times and in particular at least 2.5 times a width of the first area in the second width direction.

This results in a space-saving arrangement of the dirty fluid tank on the floor head. The dirty fluid tank can be designed with a large capacity. The first region and the second region may define a continuous contaminant fluid containment space, or a plurality of containment spaces may be provided.

It is particularly advantageous if the first area and the second area delimit a free space in which the drive motor is at least partially arranged when the dirty fluid tank is held on the floor head, the free space in particular having the shape of a hollow cuboid. This results in an optimized use of space.

In particular, the free space when the dirty fluid tank is held on the floor head facing away from the first area of the dirty fluid tank is limited by a torque transmission device. This results in an optimized use of space. The bottom head can be made compact.

• - The battery device can be removed from a rear side of the floor head;
• - The dirty fluid tank is positioned in relation to the first width direction between one end of the battery device and the at least one cleaning roller on the floor head.

This results in a space-saving structure. The receptacle or the battery device can be protected in a simple manner from dirty fluid.

It is also favorable if a receiving shaft for the battery device has an insertion opening which points to a rear side of the floor head, the rear side facing away from a front side of the floor head and the at least one cleaning roller being positioned in the area of the front side of the floor head. In this way, a battery device can be accommodated on the floor head, which is at a maximum distance from the at least one cleaning roller. This results in good protection against splashing water, dirty fluid and so on. The bottom head, in turn, can be produced in a simple manner as a result.

• - ein Ende der Aufnahme für die Batterieeinrichtung und/oder ein Ende der Batterieeinrichtung liegt bezogen auf eine Höhenrichtung des Bodenkopfs oberhalb des Schmutzfluid-Tanks und insbesondere oberhalb des ersten Bereichs;
• - bezogen auf die zweite Breitenrichtung ist die Aufnahme für die Batterieeinrichtung und/oder die Batterieeinrichtung versetzt zu dem Antriebsmotor positioniert;
• - bezogen auf die zweite Breitenrichtung ist die Aufnahme für die Batterieeinrichtung und/oder die Batterieeinrichtung versetzt zu einer Drehmomentübertragungseinrichtung positioniert;
• - bezogen auf die erste Breitenrichtung ist die Aufnahme für die Batterieeinrichtung und/oder die Batterieeinrichtung versetzt zu dem Antriebsmotor positioniert;
• - bezogen auf die erste Breitenrichtung ist die Aufnahme für die Batterieeinrichtung und/oder die Batterieeinrichtung versetzt zu einer Drehmomentübertragungseinrichtung positioniert;
• - bezogen auf eine Höhenrichtung des Bodenkopfs ist die Aufnahme für die Batterieeinrichtung und/oder die Batterieeinrichtung versetzt zu dem Schmutzfluid-Tank an dem Bodenkopf positioniert.

It is favorable if a receptacle for the battery device and/or the battery device is arranged adjacent to the first area of the dirty fluid tank, in particular with at least one of the following:

• - One end of the receptacle for the battery device and/or one end of the battery device is located above the dirty fluid tank and in particular above the first area in relation to a vertical direction of the floor head;
• - Based on the second width direction, the receptacle for the battery device and/or the battery device is positioned offset to the drive motor;
• - Based on the second width direction, the receptacle for the battery device and/or the battery device is positioned offset to a torque transmission device;
• - Based on the first width direction, the receptacle for the battery device and/or the battery device is positioned offset to the drive motor;
• - Based on the first width direction, the receptacle for the battery device and/or the battery device is positioned offset to a torque transmission device;
• - Relative to a vertical direction of the floor head, the receptacle for the battery device and/or the battery device is positioned offset to the dirty fluid tank on the floor head.

This results in a compact structure. The battery device can be integrated into the floor head to save space. A relatively low height of the floor head in the height direction can be achieved to reach. This in turn results in good accessibility under furniture and the like.

By appropriately arranging the mount, it is also possible to balance the moments on the floor head with an optimized positioning of the center of gravity.

• - die mindestens eine Reinigungswalze ist von einer gleichen Seite des Bodenkopfs entnehmbar wie der Schmutzfluid-Tank;
• - die mindestens eine Reinigungswalze ist über eine laterale Seite des Bodenkopfs entnehmbar, welche zwischen einer Vorderseite und einer Hinterseite des Bodenkopfs liegt;
• - eine Entnahmerichtung der mindestens einen Reinigungswalze von dem Bodenkopf und eine Entnahmerichtung zur Entnahme des Schmutzfluid-Tanks von dem Bodenkopf sind mindestens näherungsweise parallel;
• - die mindestens eine Reinigungswalze und der Schmutzfluid-Tank sind unabhängig voneinander von dem Bodenkopf entnehmbar und/oder an dem Bodenkopf einsetzbar.

In particular, the at least one cleaning roller sits detachably on the floor head, with at least one of the following:

• - The at least one cleaning roller can be removed from the same side of the floor head as the dirt fluid tank;
• - the at least one cleaning roller can be removed via a lateral side of the floor head, which lies between a front side and a rear side of the floor head;
• - A removal direction of the at least one cleaning roller from the floor head and a removal direction for removing the dirty fluid tank from the floor head are at least approximately parallel;
• - The at least one cleaning roller and the dirty fluid tank can be removed independently of one another from the floor head and/or can be used on the floor head.

A compact design of the floor head results. The cleaning roller and the dirt fluid tank can be easily removed by removing it from a lateral side. For example, the at least one cleaning roller and the dirty fluid tank can also be removed when the floor cleaning device is standing up at a floor station.

In particular, it is provided that the floor head has a first chamber and a second chamber, that a partition is provided which spatially separates the first chamber and the second chamber from one another, that the drive motor is arranged in the first chamber and the at least one cleaning roller is or is arranged in the first chamber, and that electronic components and/or at least one valve and/or a pump and/or a battery device are arranged in the second chamber.

In this solution, a dividing wall is provided which divides the bottom head into a first part with the first chamber and a second part with the second chamber, with a spatial separation being provided. As a result, functional components that are exposed to dirt fluid can be separated from components that may only be exposed to a small amount of dirt fluid, such as electronic components.

The partition allows the second chamber to be separated from the first chamber in a fluid-protected manner. In particular, this achieves splash water protection for the second chamber. In principle, it is possible for the partition wall to be designed to be fluid-tight. In an advantageous embodiment, the partition wall is not designed to be completely fluid-tight and includes one or more (small) openings towards the first chamber, so that liquid that collects in the second chamber can flow out. However, the at least one opening is arranged and designed in such a way that the second chamber is substantially protected against fluids (protection against the ingress of media) by the partition and in particular protection against splashing water.

Advantageously, it is provided that during operation of the floor cleaning device, at least a partial area of an interior of the first chamber is exposed to dirt and/or liquid, and that the second chamber is protected by the partition against the ingress of dirt and liquid. As a result, a separation into a clean area and a dirty area can be carried out to a certain extent, with the clean area being fluid-protected with the second chamber. This fluid protection can be an encapsulation with a fluid-tight partition wall, or it can at least be protection against splashing water and the like with, for example, small openings in the partition wall, which prevent liquid from accumulating in the second chamber by allowing liquid to drain through such openings. As a result, for example, electronic components can be arranged in this.

• - die Trennwandung zwischen der ersten Kammer und der zweiten Kammer ist mindestens mit einem Teilbereich quer zu einer Normalen der Aufstellebene orientiert;
• - die zweite Kammer ist bezogen auf eine Höhenrichtung, welche senkrecht zu der Aufstellebene ist, oberhalb der ersten Kammer angeordnet.

It is favorable if the floor head is assigned an installation level for installation on a floor to be cleaned, with at least one of the following:

• - The partition wall between the first chamber and the second chamber is oriented at least with a partial area transverse to a normal of the installation plane;
• - The second chamber is based on a vertical direction, which is perpendicular to the installation plane, arranged above the first chamber.

As a result, the dividing wall results in a separation into a lower part and an upper part of the bottom head. The result is an optimized positionability of corresponding com ponents with simple manufacturability of the floor head.

• - die zweite Kammer ist geschlossen;
• - die erste Kammer ist mindestens in einem Teilbereich und insbesondere zu der mindestens einen Reinigungswalze hin offen.

It is favorable if at least one of the following is provided:

• - the second chamber is closed;
• - The first chamber is open at least in a partial area and in particular towards the at least one cleaning roller.

This results in an optimized cleaning result with a simple structure.

• - die erste Kammer umfasst eine Aufnahmekammer für einen Schmutzfluid-Tank;
• - die erste Kammer umfasst einen Aufnahmeschacht für die mindestens eine Reinigungswalze und/oder der Aufnahmeschacht ist an der ersten Kammer angeordnet.

It is also favorable if at least one of the following is provided:

• - The first chamber comprises a receiving chamber for a dirty fluid tank;
• - The first chamber comprises a receiving shaft for the at least one cleaning roller and/or the receiving shaft is arranged on the first chamber.

Basically, the area around a dirty fluid tank is exposed to dirty fluid. The arrangement on or in the first chamber, including the receiving shaft, results in a compact structure that is easy to manufacture. Electronic components and the like in the second chamber can be optimally protected.

It is favorable if the second chamber is closed by a first cover. This results in simple manufacturability.

• - der erste Deckel ist permanent fest mit dem Bodenkopf verbunden;
• - der erste Deckel schließt bezogen auf eine Höhenrichtung die zweite Kammer nach oben;
• - der erste Deckel bildet zumindest teilweise eine Oberseite des Bodenkopfs;
• - der erste Deckel ist mehrteilig oder mit mehreren Bereichen ausgebildet.

It is then advantageous if at least one of the following is provided:

• - the first cover is permanently connected to the bottom head;
• - The first cover closes the second chamber upwards in relation to a vertical direction;
• - The first cover at least partially forms an upper side of the bottom head;
• - The first cover is designed in several parts or with several areas.

This results in a compact construction of the bottom head with simple manufacturability.

It is favorable if the second chamber and/or a first cover of the second chamber has a recess or bulge or depression which has a recessed area compared to an upper side of the bottom head. If a retaining rod device is arranged on the base head, a small pivoting angle (relative to an installation plane of the base head) can be achieved via the recess or bulge or indentation when the retaining rod device can pivot. This results in optimized accessibility.

• - mindestens ein Halter für eine Reinigungswalze;
• - ein Halter für eine Haltestabeinrichtung;
• - eine Gelenkeinrichtung für eine Haltestabeinrichtung, über welche die Haltestabeinrichtung schwenkbar zu dem Bodenkopf gehalten ist.

It is also beneficial if at least one of the following is positioned on the recessed area:

• - At least one holder for a cleaning roller;
• - a holder for a support rod device;
• - A joint device for a support rod device, via which the support rod device is pivotally held to the floor head.

The arrangement of the holder for a cleaning roller results in an optimized use of space. When the floor cleaning device is not in operation, the cleaning roller can be held on the holder for a cleaning roller, for example for drying. The arrangement of the articulated device or the holder for a holding rod device (for operation by a standing operator) allows a small pivoting angle to be achieved so that furniture and the like can be driven under under it in an optimized manner.

• - die Ausnehmung oder Ausbuchtung oder Vertiefung erstreckt sich längs der ersten Breitenrichtung und weist eine Ausdehnung in der zweiten Breitenrichtung auf;

In particular, the bottom head has a first width direction transverse to the axis of rotation and a second width direction parallel to the axis of rotation, with at least one of the following:

• - the recess or bulge or depression extends along the first width direction and has an extent in the second width direction;
• - the recess or bulge or indentation is open to a front and/or a rear of the bottom head;
• - A receptacle for a battery device and/or a battery device is arranged next to the recess or bulge or depression in relation to the first width direction;
• - The at least one cleaning roller is arranged in relation to the first width direction in front of the recess or bulge or depression;
• - A scraper device for scraping dirt fluid from the at least one cleaning roller and/or a hairpin device for picking up hair is arranged in front of the recess or bulge or depression in relation to the first width direction;
• - a third chamber is arranged in front of the recess or spread or depression with respect to the first width direction.

If the recess is open to a front side and/or a rear side of the floor head, liquid (such as dirty fluid) that collects there can flow off.

The arrangement of the receptacle for the battery device or the battery device next to the recess or bulge or depression results in an optimized use of space. For example, a torque balance can also be achieved in connection with the drive motor.

If the at least one cleaning roller is arranged in front of the recess or bulge or depression in relation to the first width direction, this results in an optimized use of space.

If a wiper device for wiping off dirty fluid and/or a hairpin device is arranged in front of the recess or bulge or depression, this results in an optimized use of space.

In particular, a third chamber is provided. For example, a hair pin device can be removed and cleaned via this.

In one exemplary embodiment, a third chamber is arranged on the bottom head, with the second chamber being closed in a fluid-tight manner with respect to the third wall by a wall or a further wall. The third chamber can be opened, for example. In the third chamber, for example, a detachable hairpin device is arranged, which can be removed for cleaning and then reinserted.

• - die dritte Kammer ist in Richtung zu der mindestens einen Reinigungswalze vor der zweiten Kammer angeordnet;
• - die dritte Kammer ist bezogen auf eine Höhenrichtung oberhalb mindestens eines Teilbereichs der mindestens einen Reinigungswalze angeordnet;
• - an der dritten Kammer ist insbesondere entnehmbar eine Abstreifereinrichtung zum Abstreifen von Schmutzfluid von der mindestens einen Reinigungswalze und/oder eine Haarpineinrichtung positioniert;
• - die dritte Kammer ist durch einen abnehmbaren zweiten Deckel geschlossen, insbesondere mit mindestens einem der Folgenden:
  • - der zweite Deckel bildet zumindest teilweise eine Oberseite des Bodenkopfs;
  • - der zweite Deckel ist bündig zu einem ersten Deckel der zweiten Kammer;
  • - der zweite Deckel ist in einer Richtung quer zu der Rotationsachse von dem Bodenkopf abnehmbar.

It is favorable if at least one of the following is provided:

• - the third chamber is arranged in the direction of the at least one cleaning roller in front of the second chamber;
• - the third chamber is arranged in relation to a vertical direction above at least a partial area of the at least one cleaning roller;

  • - The second lid at least partially forms an upper side of the bottom head;
  • - The second lid is flush with a first lid of the second chamber;
  • - the second lid is detachable from the bottom head in a direction transverse to the axis of rotation.

The provision of the third chamber with at least one of the features mentioned results in an optimized use of space. A wiper device and/or hair pin device can be easily removed for cleaning.

The second lid results in a closed surface for the bottom head.

It is particularly advantageous if the partition wall has a first area which separates the first chamber from the second chamber in a splash-proof manner. This results in a space-saving design with a separation in terms of functional components that can be subject to contamination fluid and components that must not be "systematically" subjected to contamination fluid.

In particular, the dividing wall has a second area, or a further dividing wall is provided which separates the second chamber from a third chamber in a fluid-tight manner, with the second area or the further dividing wall being oriented transversely and in particular perpendicularly to the first area. As a result, the second chamber can be designed to be splash-proof in order to arrange electronic components and the like there in a protected manner. The third chamber located next to it results in a space-saving design.

In particular, the first area forms a floor for the third chamber. This results in a space-saving structure.

• - the electronic components;
• - a support bar means;
• - At least part of a rotary bearing device for the at least one cleaning roller;
• - A support device for supporting the floor head on a floor to be cleaned;
• - a blower device.

This results in an optimized structure and the number of structural components can be kept low.

In one embodiment, the structural support is designed as a support plate or includes a support plate. As a result, the floor head in particular can be designed with small height dimensions in order to obtain good accessibility under furniture or the like.

In one embodiment, the partition wall has at least one recess or at least one bulge or at least one depression on which functional components are seated. This allows the recording volume to be increased. This in turn results in a space-saving design, in particular with regard to height dimensions. This, in turn, allows for good accessibility under furniture or the like.

In particular, the at least one recess or at least one bulge or at least one indentation is outside of an area in which a dirty fluid tank is positioned and in particular outside of a receiving chamber for the dirty fluid tank. As a result, the dirty fluid tank can be designed with a large holding volume for dirty fluid.

• - die Trennwandung weist eine erste Ausnehmung oder eine erste Ausbuchtung oder eine erste Vertiefung auf, an welcher zumindest ein Teil der elektronischen Komponenten sitzt;
• - die Trennwandung weist eine zweite Ausnehmung oder eine zweite Ausbuchtung oder eine zweite Vertiefung auf, an welcher eine Batterieeinrichtung und/oder Aufnahme für eine Batterieeinrichtung sitzt;
• - die Trennwandung weist eine dritte Ausnehmung oder eine dritte Ausbuchtung oder eine dritte Vertiefung auf, an welcher das Magnetventil sitzt.

It is favorable if at least one of the following is provided:

• - The partition wall has a first recess or a first bulge or a first depression on which at least part of the electronic components is seated;
• - The partition wall has a second recess or a second bulge or a second depression on which a battery device and/or receptacle for a battery device is seated;
• - The partition has a third recess or a third bulge or a third depression on which the solenoid valve is seated.

This results in an optimized use of space, in particular also for the second chamber.

• - die mindestens eine Ausnehmung oder mindestens eine Ausbuchtung oder mindestens eine Vertiefung weist in die erste Kammer und erhöht das Aufnahmevolumen der zweiten Kammer. Dadurch ergibt sich eine optimierte Platznutzung.

It is also favorable if at least one of the following is provided:

• - The at least one recess or at least one bulge or at least one depression points into the first chamber and increases the capacity of the second chamber. This results in an optimized use of space.

It is favorable if a dirty fluid tank is positioned between the first recess or first bulge or first indentation and the at least one cleaning roller and/or between the second recess or second bulge or second indentation and the at least one cleaning roller. This results in an optimized use of space.

It is also favorable if the partition wall has a further recess or further bulge, which is arranged above the drive motor and/or a torque transmission device in relation to a vertical direction. In particular, the holding volume of the first chamber is increased by this further recess or further bulge. A space-saving design of the floor head can thus be achieved with optimized use of the available space.

It is favorable if the dividing wall extends from a rear end of the floor head to the at least one cleaning roller. This results in a simple structure that is easy to manufacture.

For the same reason it is favorable if the partition wall extends between opposite lateral sides of the bottom head.

In one embodiment, the floor cleaning device according to the invention is designed as a hand-held floor cleaning device with a holding rod device which is pivotably seated on the floor head. An operator who stands up on the floor to be cleaned can then guide the floor cleaning device over the floor to be cleaned while standing.

Alternatively, the floor cleaning device can also be designed as a self-propelled and self-steering floor cleaning device (“cleaning robot”).

An embodiment of a floor cleaning device according to the invention 20, which in the 1 until 17 1 includes a base head 22. Attached to the base head 22 is a support rod assembly 24. FIG. The support rod device 24 is connected to the base head 22 via a joint device 26 . This is explained in more detail below. The holding rod device 24 is pivoted about (at least) one pivot axis 28 (cf 6 ) relative to the floor head 22 and thus also to a floor 30 to be cleaned (cf 7 ) swivelling.

The support rod assembly 24 has a proximal end 32 and a distal end 34 relative to an operator. At or near distal end 34 , support rod assembly 24 is pivotally connected to base head 22 via pivot assembly 26 about pivot axis 28 .

The length between the proximal end 32 and the distal end 34 of the holding rod device 24 is designed such that an operator standing on the floor 30 to be cleaned can guide the floor cleaning device 20 while standing over the floor 30 to be cleaned. A size adjustment to the operator is possible due to the ability to pivot about the pivot axis 28 .

For this guidance over the floor, a bracket 36 is arranged in the region of the proximal end 32 on the holding rod device 24, via which an operator can grip and guide (push and pull) the floor cleaning device 20 during operation (when guiding over the floor 30 to be cleaned). .

In one embodiment, the yoke 36 is in the form of a closed loop.

In one embodiment, control elements and/or display elements 38 are arranged on the holding rod device 24 and in particular on the bracket 36 . A control element is, for example, an on/off switch. For example, it is also possible to adjust the supply of cleaning fluid (in particular quantitatively) to a cleaning roller. A display element is, for example, a display of the switched-on or switched-off state of the operating device 20 or the amount of water supplied.

In one embodiment, controls and indicators are integrated.

The support rod device 24 comprises a rod 40 with a longitudinal axis 42. The bracket 36 protrudes from the longitudinal axis and points in particular to a rear side 44 of the base head 22.

When the floor cleaning device 20 is properly operated and guided over the floor 30 to be cleaned, an operator stands in relation to a forward direction 46 (cf 7 ) when guiding the floor cleaning device 20 over the floor 30 to be cleaned behind the rear side 44.

The pivot axis 28 is oriented transversely and in particular perpendicularly to the longitudinal axis 42 of the rod 40 .

A body 48 is seated on the retaining rod device 24 in the region of the proximal end 32. The body 48 can be pivoted with the retaining rod device 24 about the pivot axis 28. A cleaning liquid tank 50 is detachably held on the body 48 . The cleaning liquid tank 50 is used to hold a cleaning liquid. The cleaning liquid can be pure water or a mixture of pure water with a cleaning agent and, in particular, a surfactant cleaning agent.

In one exemplary embodiment, the cleaning liquid tank 50 has opposite cheeks 52a, 52b, between which a recess 54 is formed. When the cleaning fluid tank 50 is seated on the support rod assembly 24 and thereby on the rod 40, the rod 40 is immersed in the recess 54 between the cheeks 52a, 52b.

In particular, the cleaning liquid tank 50 and the body 48 also do not protrude beyond the rod 40 to a front side 56 of the base head 22 beyond the rod 40 . The front side 56 of the bottom head 22 faces away from the rear side 44 .

In one embodiment, the height of the combination of body 48 and cleaning liquid tank 50 in the longitudinal axis 42 is at most 50% of the corresponding height of the rod 40 along the longitudinal axis 42 between the hinge device 26 and the bracket 36. In particular, the total height of the combination of body 48 and cleaning liquid tank 50 at most 33% of the total length mentioned.

The body 48 and the cleaning liquid tank 50, which sits on the body 48, protrudes beyond the rod 40 to the rear side 44.

During operation of the floor cleaning device 20, the holding rod device is about the pivot axis 28 in a pivoting range 58 (cf 6 ) which is between a minimum angle and a maximum angle. The minimum angle of the pivoting range 58 is defined in that the body 48 or the cleaning liquid tank 50 hits the floor head 22 . Alternatively, a corresponding blocking element can be provided in front of the stops.

An installation level 60 is assigned to the floor head 22 . This is explained in more detail below. If the floor head 22 stands up on a level floor 30 to be cleaned, then this installation level 60 coincides with the floor 30 .

Said minimum angle is small relative to the installation plane 60. In relation to the angle between the longitudinal axis 42 and the installation plane 60, it is in the range between 0° and 10°, for example.

The maximum angle of the pivoting range 58 is the angle between the installation plane 60 and the longitudinal axis 42 of the support rod device 24 in the range between 80° and 110°.

In a specific exemplary embodiment, it is approximately 90°.

It is provided that the floor cleaning device 20 has a parking position 62 for the holding rod device 24 . This parking position 62 is in 1 shown.

In this parking position 62, the support rod device 24 is at the maximum angle of the pivoting range 58 or outside of this maximum angle. The support rod device 24 is transverse to the base head 22. In the parked position 62, this position of the support rod device 24 relative to the base head 22 is secured, so that a certain amount of force is required to pivot the support rod device 24 out of the parked position 62.

The parking position 62 can be secured, for example, by means of a force fit or form fit. In one exemplary embodiment, a magnetic device is provided, with the parking position of the holding rod device 24 relative to the floor head 22 being held by corresponding magnetic forces. For example, a positive connection such as a snap connection or the like can also be provided.

In one exemplary embodiment, a floor station 64 is assigned to the floor cleaning device 20 . The floor station 64 is used to store the floor cleaning device 20 outside of a cleaning operation. The floor cleaning device 20 can be set up with its floor head 22 on this.

As explained in more detail below, (at least) one cleaning roller 66 is held on the floor head 22 during cleaning operation.

As will also be explained below, a receptacle 68 for a cleaning roller 66 is arranged on the bottom head 22 . The cleaning roller 66 can be used on the receptacle 68 after the end of a cleaning operation, in order to dry it and also to store it.

this is in 1 shown with the cleaning roller 66 seated on the corresponding receptacle 68.

The bottom head 22 has a first width direction 70 (cf 7 ). The first width direction 70 extends between the rear side 44 and the front side 56 of the floor head 22. The first width direction 70 is at least approximately parallel to the forward direction of travel 60.

Furthermore, the bottom head 22 has a second width direction 72. The second width direction 72 is transverse and in particular perpendicular to the first width direction 70.

The first width direction 70 and the second width direction 72 are in particular both parallel to the installation plane 60 of the floor cleaning device 20 (and thus of the floor head 22).

Furthermore, the bottom head 22 has a vertical direction 74 . Height direction 74 is perpendicular to first width direction 70 and perpendicular to width direction 72. Height direction 74 is also perpendicular to installation plane 60.

In one embodiment, the base head 22 has an approximately cuboid shape (related to its envelope surfaces), with an extension in a first width direction 70, the second width direction 72 and the height direction 74.

The bottom head 22 has a first lateral side 76 and an opposite second lateral side 78 . The lateral sides 76, 78 are oriented transversely and in particular at least approximately perpendicularly to the second width direction 72. The lateral sides 76, 78 are oriented at least approximately parallel to the first width direction 70.

The first lateral side 76 and the second lateral side 78 each connect (spaced apart from one another in the second width direction 72) the rear side 44 to the front side 56 of the bottom head 22.

The bottom head 22 includes a structural support 80 (see particularly 9 ).

The structural support 80 ensures the structural stability of the floor head 22 and can absorb corresponding forces and torques. Functional components of the floor cleaning device 20 are fixed directly or indirectly to the structural support 80 .

The structural support 80 is designed in such a way that it divides the floor head 22 into a lower part 82 and an upper part 84 in relation to the vertical direction 74 . The lower part 82 is closer to the installation level 60 than the upper part 84.

In one exemplary embodiment, the structural support 80 is plate-shaped and extends in the first width direction 70 and the second width direction 72 .

A thickness of the structural support 80 in the height direction 74 is considerably smaller than the extension in the first width direction 70 and the extension in the second width direction 72. (In particular, the thickness of the structural support 80 in the height direction 74 is 5 cm or less.)

A plate-like shape is considered to be that the thickness in the height direction 74 is considerably smaller than the corresponding widths in the first width direction 70 and the second width direction 72.

The structural support 80 includes a partition wall 86 which ensures a spatial separation between the upper part 84 and the lower part 82 . The dividing wall 86 as a spatial dividing wall can be fixed to the structural support 80 or the structural support 80 itself can be designed in such a way that it forms the dividing wall 86 as a dividing wall between the upper part 84 and the lower part 82 . The baffle 86 also forms a "media baffle" which provides fluid protection from liquid/contaminant fluid intrusion into the top 84 .

The partition wall 86 follows the shape of the structural support 80.

In one embodiment, the partition wall 86 and with it the structural support 80 extends from the rear side 44 of the floor head 22 to the cleaning roller 66 in the first width direction 70.

In the second width direction 72, the partition wall 86 and the structural support 80 extend from the first lateral side 76 to the second lateral side 78 in the second width direction 72.

It can be provided that the structural support 80 and the partition 86 to an outer side is provided with a covering such as a housing part.

Relative to a central plane 88 of the partition wall 86 or of the structural support 80, these are oriented transversely and in particular perpendicularly to the vertical direction 74. They are also oriented at least approximately parallel to the installation level 60 (cf 9 ).

A first chamber 90 is arranged on the lower part 82 of the bottom head 22 . A second chamber 92 is arranged on the upper part 84 . Furthermore, a third chamber 94 is arranged on the upper part 84 in the first width direction 70 adjacent to the second chamber 92 .

The second chamber 92 faces the rear 44 . The third chamber 94 faces the front side 56 . In relation to the vertical direction 74, the third chamber 94 lies at least in a partial area above the cleaning roller 66.

The partition wall 86 ensures that the first chamber 90 and the second chamber 92 are spatially separated from one another and thereby represents a fluid protection in order to largely prevent the ingress of spray water and the like into the second chamber 92 . In principle, it is possible for the dividing wall 86 to be provided with one or more (small) openings that do not eliminate the splash water protection but can drain from the second chamber 92 into the first chamber 90 via the liquid that has nevertheless penetrated, for example.

The first chamber 90 includes a floor 96 (see, for example, FIG 15 ), which closes off the first chamber 90 from the installation level 60.

The floor 96 is supported to the structural support 80 by one or more walls or posts 98 in one embodiment (see FIG 17 ).

The base 96 can alternatively or additionally be part of a housing 100 of the base head 22 .

At least one supporting element 102 (cf 15 ) arranged. The cleaning roller 66 is located in the area of the front side 56 of the floor head 22 or defines this front side. The at least one support element 102 is located in the area of the rear side 44 of the floor head 22.

During cleaning operation, the floor cleaning device 20 is supported on the floor 30 to be cleaned via the cleaning roller 66 and the at least one support element 102 via the floor head 22 . The at least one support element 102 and the cleaning roller 66 define the installation plane 60 for the floor head 22 on the floor 30 to be cleaned.

One or more (in particular two) support rollers are provided as the support element 102 . Alternatively, one or more runners can also be provided. In principle, it is also possible for a further cleaning roller to form a support element 102 at a distance from the cleaning roller 66 .

A drive motor 104 for driving the cleaning roller 66 in rotation is arranged on the bottom head 22 . The drive motor 104 is an electric motor.

It sits in the first chamber 90 on the lower part 82 and is in particular held by the structural support 80 or mounted on it.

In one embodiment, the drive motor 104 is located in a central region between the front side 56 and the rear side 44 of the floor head 22 in relation to the first width direction 70. In particular, a center of gravity of the floor head 22 (without the support rod device 24) is on the drive motor 104.

The drive motor 104 has an extension in the second width direction 72, which is smaller than the extension of the bottom head 22 in the second width direction 72 (cf 5 ). The drive motor 104 has a first end face 106 and an opposite second end face 108 (cf 5 ). The first face 106 faces the first lateral side 106 . The second face 108 faces the second lateral side 78 . A distance between the first lateral side 76 and the first end face 106 is greater than a distance between the second end face 108 and the second lateral side 78. The base head 22 is assigned a first center plane 110 (cf 7 ). The first median plane 110 is perpendicular to the first width direction 70. The second width direction 72 is parallel to the first median plane 110. The first median plane 110 is centered between the front 56 and the rear 44 of the bottom head 22.

Furthermore, the bottom head 22 is a second center plane 112 ( 7 ) assigned. The second midplane 112 is perpendicular to the second widthwise direction 72. The first widthwise direction 70 is parallel to the second midplane 112. The second midplane 112 is midway between the first lateral side 76 and the second lateral side 78.

In one exemplary embodiment, the drive motor 104 is located on the first center plane 110 (cf 5 ).

The bottom head 22 is (virtually) divided by the second center plane 112 into a first region 114a between the second center plane 112 and the first lateral side 76, and into a second region 114b between the second center plane 112 and the second lateral side 78. The drive motor 104 is seated in the second area 114b and at most a part 104 that is smaller in the second width direction 72 is seated in the first area 114a.

In one embodiment ( 5 ) the first end face 106 touches the second center plane 112 or is arranged at a distance therefrom in the second region 114b.

The drive motor 104 includes a drive shaft having a drive shaft axis of rotation 116 ( 5 ). The drive shaft axis of rotation 116 is parallel to the second width direction 72.

The driveshaft axis of rotation 116 meets (in an imaginary extension) the first lateral side 76 and the second lateral side 78.

A torque transmission device 118 is arranged on the bottom head 22 in the region of the second end face 108 . The torque transmission device 118 is in particular mounted on the structural support 80 .

The torque transmission device 118 serves to transmit the torque of the drive shaft of the drive motor 104 to the cleaning roller 66 .

The torque transmission device 118 is designed, for example, as a belt drive.

The corresponding torque of the drive motor 104 can be transmitted in a section 120 via the torque transmission device 116 .

The torque transmission device 118 is arranged along and in particular parallel to the second lateral side 78 on the floor head 22 .

Provision can also be made for the torque transmission device 118 to reduce the speed, so that the cleaning roller 66 rotates at a lower speed when the floor cleaning device 20 is in operation than the drive shaft of the drive motor 104.

The torque transmission device 118 includes an output element 122, via which a corresponding torque is coupled directly into the cleaning roller 66 for its rotation.

The output element 122 is positioned at a distance from the drive shaft of the drive motor 104 .

The output element 122 sits in particular in the second area 114b and is preferably held by the structural support 80 or a wall of the lateral side 78 . The output element 122 rotates about an axis of rotation 124.

Torque transmission device 118 is seated in first chamber 90.

The driven element 122 is seated at least partially in the first chamber 90 and protrudes into a receiving shaft 126 for the cleaning roller 66.

The cleaning roller 66 comprises a hollow-cylindrical carrier 128, in particular made of a plastic material (cf 17 ). Cleaning material 130 is arranged as trimmings on the carrier. In one embodiment, the cleaning material 130 is a textile material and in particular a microfiber material. In principle, the cleaning material can also be formed by brushes. Furthermore, for example, a combination of textile material and brushes is also possible.

In one exemplary embodiment, a handle 129 is arranged on the hollow-cylindrical carrier 128 (e.g 1 and 7 ), via which the cleaning roller 66 can be held by an operator and can also be removed without having to touch the trimmings, which may be covered with dirt. This corresponding handle 129 is integrated in particular in the hollow-cylindrical carrier 128 and is designed in such a way that a driver for a rotary bearing device 132 (see below) is “integrated” or the handle is set back in relation to the driver.

The carrier 128 is designed on one side in such a way that it can be slipped onto the driven element 122 in the receiving shaft 126 in a rotationally fixed manner.

The cleaning roller 66 is mounted on the bottom head 22 via a rotary bearing device 132 such that it can rotate about an axis of rotation 134 . The pivot bearing device 132 includes a first pivot bearing 136 and a second pivot bearing 138 as an abutment. The first pivot bearing 136 is fixedly arranged on the bottom head 22 and thereby arranged on the first chamber 90 . The first rotary bearing 136 is formed in particular by the driven element 122 .

As mentioned above, the cleaning roller 66 can be pushed onto the driven element 122 in a rotationally fixed manner via the carrier 128 .

The axis of rotation 134 of the cleaning roller 66 then coincides with the axis of rotation 134 of the driven element 122 .

The axis of rotation 134 of the cleaning roller 66 is parallel to the second width direction 72 and is transverse and in particular perpendicular to the first width direction 70.

The forward direction 46 is perpendicular to the axis of rotation 134 of the cleaning roller 66.

The axis of rotation 134 lies in particular parallel to the installation plane 60.

The cleaning roller 66 has a first end face 140 and an opposite second end face 142 . The cleaning roller 66 is held on the first pivot bearing 136 via its first end face 140 . The cleaning roller 66 is held on the second pivot bearing 138 via its second end face 142 . As a result, the cleaning roller 66 is suspended on the end face of the pivot bearing device 132 between the first pivot bearing 136 and the second pivot bearing 138 .

The second pivot bearing 138 as an abutment is attached to a cover 144 (compare, for example, 12 ) arranged and detachable as a whole from the bottom head 22.

The cover 144 closes the receiving shaft 126 in an openable and in particular detachable manner on the first lateral side 76 .

The second pivot bearing 138 is seated on the cover 144 and includes a roller bearing 146 and in particular ball bearings ( 12 ). The cleaning roller 66 with its carrier 128 can be inserted onto the second pivot bearing 138 via the second end face 142 . During operation, the cleaning roller 66 is set in rotation via the driven element 122 and the second pivot bearing 138 as an abutment is a driving bearing, which enables rotation about the axis of rotation 134 and also spaced the cleaning roller 66 from the first pivot bearing 136 (the driven element 122) in the Area of the first lateral side 76 of the bottom head 22 is supported.

The cover 144 can be detached and fixed to the bottom head 22 in a detachable manner. Alternatively, it can also be movably (non-detachably or additionally detachably) connected to the bottom head 22 . A pivot bearing or displacement bearing or a combination thereof is provided for this purpose, for example.

In one embodiment, a pin 148 is disposed on cover 144 . This pin 148 is (when the cover 144 is seated on the bottom head 22 ) arranged at a distance from the second rotary bearing 138 and at the same time arranged at a distance from the axis of rotation 134 of the cleaning roller 66 . The pin 148 is used to absorb torque.

The pin 148 extends parallel to the axis of rotation 134 or parallel to the second width direction 72.

A recess 150 which is open towards the first lateral side 76 is provided on the bottom head 22 . This recess 150 serves to receive the pin 148. This is in a direction 152 (see for example 4 ) can be pushed into the recess 150.

The recess 150 is arranged above the receiving shaft 126 in the region of the third chamber 94 in relation to the vertical direction 74 in particular.

The cover 144 is secured via a fixing device 154 (cf 12 ) can be fixed with the floor head 22. The fixing device 154 comprises, for example, a spring-supported movable element 156 (cf 12 until 15 ), which can be connected to the bottom head 22 outside of the cover 144 in the manner of a detachable snap connection.

In the 13 and 14 a fixed state is shown, in which a fixation takes place via the corresponding movable element 156 by positive locking. In an alternative embodiment, a frictional connection such as a magnetic connection is provided.

When the lid 144 is affixed to the bottom head 22, it forms part of the first lateral side 76 (see, for example, FIG 2 ).

In relation to the second center plane 112, the bottom head 22 is asymmetrical in the area of the cleaning roller 66. The bottom head 22 includes a bridge 158 on the first chamber 90. This bridge 158 receives the torque transfer device 118 thereon. A width of this bridge 158 in the second width direction 72 is greater than a width of the cover 144 in the second width direction 72.

The output element 122 protrudes from the bridge 158 (see, for example, FIG 4 ).

The receiving shaft 126, when the cleaning roller 66 is seated on the bottom head 22, is towards the second lateral side 78 through the bridge 158 limited. It is delimited by the cover 144 towards the first lateral side 76 .

Towards the rear 44 it is delimited by a dirty fluid tank 160 .

It is delimited at the top by a wall of the third chamber 94 .

The receiving shaft 126 is open towards the installation level 60 at the bottom. The cleaning roller 66 protrudes in this direction on the receiving shaft 126, precisely to enable floor cleaning.

In one embodiment, the receiving well 126 is also open to the front side 56 . The cleaning roller 66 protrudes forward from this open area in order to enable cleaning close to the edge, for example.

The cleaning roller 66 can be moved in a direction 162 opposite to the direction 152 (cf 4 ) from the receiving shaft 126 and thereby remove from the bottom head 22. In order to remove the cleaning roller 66 from the floor head 22, the movable element 156 is acted upon in order in particular to release the form-fitting connection. The cover 144 (cf 4 ) can be removed.

In principle, it is possible here for the cover 144 to be removed first and for this to be removed from the bottom head 22 and from the cleaning roller 66 . The cleaning roller 66 can then be removed from the receiving shaft 126 in the opposite direction 162 .

However, it is also possible to remove the cover 144 with the cleaning roller 66 fixed thereto in the opposite direction 162 and thereby to pull the cleaning roller 66 out of the receiving shaft 126 in the opposite direction 162 .

In principle, it is possible to pull the cleaning roller 66 out of the receiving shaft 126 simply by touching the cover 144 so that, for example, an operator does not have to touch a dirty cleaning roller 66 .

The cleaning roller 66 is fixed to the bottom head 22 accordingly. To do this, first (with the cover 144 accepted) the cleaning roller 66 is pushed into the receiving shaft 126, and in the process is pushed until the cleaning roller 66 is pushed onto the first end face 140 of the driven element 122 becomes. The cover is then inserted in the direction 152 and the second pivot bearing 138 is also pushed onto the cleaning roller 66 .

Alternatively, the cleaning roller 66 can be pushed onto the second pivot bearing 138 of the cover 144 and with this combination the cleaning roller 66 is then pushed into the receiving shaft 126 and a displacement then takes place until the cover 144 engages via the fixing device 154.

The cover 144 can be removed from the cleaning roller 66 . The cover 144 is part of the bottom head 22 and is not integrated into the cleaning roller 66 . The cleaning roller 66 can (after removal from the cover 144) itself be cleaned in a washing machine, for example.

The drive motor 104 is arranged in the first chamber 90 and the torque transmission device 118 is arranged. The first chamber 90 also houses the cleaning roller 66 . The first chamber 90 is closed off from the installation level 60 via the floor 96 . It is open towards the front side 56 due to the positioning of the cleaning roller 66 .

The first chamber 90 has a receiving chamber 164 for the dirty fluid tank 160 . This is explained in more detail below.

In one exemplary embodiment, a partition wall 168 is arranged between receiving chamber 164 for dirty fluid tank 160 and a receiving space 166 in which drive motor 104 is seated 86 oriented.

In principle, at least the receiving chamber 164 can be loaded with dirt, dirt fluid or liquid.

Provision is made for the drive motor 104 and also the torque transmission device 108 to be seated in the first chamber 90 in a correspondingly protected manner.

In one embodiment, the floor 96 (cf 17 ) designed to be open in the area of the dirty fluid tank 160 when it is seated on the base 22.

The second chamber 92 has a receiving space 170. The receiving space 170 is closed at the top (facing away from the partition 86) by a first cover 172 in a fluid-tight manner. The first lid 172 is permanently connected to the bottom head 22 . It is not provided that in normal Operation of the floor cleaning device 20, the lid 172 is opened.

Components of the cleaning device 10 which are sensitive to liquid and dirty fluid are arranged in the closed chamber 90 .

Electronic components in particular are arranged in the second chamber 92 . These are in particular provided with a fluid-tight encapsulation. A circuit 174 is positioned in the second chamber 92 and specifically includes a controller.

Furthermore, a valve such as a solenoid valve 176 (cf 17 ) located in the second chamber 92. Alternatively, a pump can be provided.

The floor cleaning device 20 comprises a feed device 178 (in 8th a partial area is shown), via which cleaning liquid can be supplied from the cleaning liquid tank 50 to a nozzle device 180 on the floor head. The nozzle device 180 is in particular arranged and designed in such a way that cleaning liquid can be fed to the cleaning material 130 of the cleaning roller 66 via it. This allows it to be moistened. The moistened material in turn acts on the floor 30 to be cleaned and dirt can be detached more easily.

In particular, feed device 178 includes one or more lines from cleaning liquid tank 50 to nozzle device 180.

The transport of cleaning liquid to the nozzle device 180 from the cleaning liquid tank 50 is driven by gravity. Alternatively, the above-mentioned pump or the like can also be provided.

The solenoid valve 176 serves to control or release the supply of cleaning liquid to the nozzle device 180 .

The electronic part of the solenoid valve 176 is arranged in the second chamber 92 and can then act on the feed device 178 outside of the first chamber 92 accordingly.

In one exemplary embodiment, it is provided that the partition wall 86 or the structural support 80 has a first recess or bulge or depression 182 in the direction of the lower part 82 . As a result, the accommodating volume of the accommodating space 170 is increased.

The circuit 174 sits in this first recess 182.

In one exemplary embodiment, a second recess 184 is provided, on which a receptacle 186 for a battery device is seated.

A third recess 188 is also provided, in which the solenoid valve 176 sits (see also Fig 10 ).

An opening 190 is positioned at the first recess 182, through which (with a corresponding sealing device) cables are passed to the drive motor 104.

A further bulge 192 (cf 8th ) arranged, which increases the capacity of the first chamber 90. This bulge 192 points upwards into the upper part 84 and is arranged in the area of the drive motor 104 in order to be able to accommodate it in a space-saving manner.

In principle, a corresponding bulge can also be provided for the torque transmission device 118 .

The recesses 182, 184, 188, 192 allow the space on the floor head 22 to be used in an optimized manner in order to keep the overall height of the floor head 22 low in the height direction 74 and thus enable good undercarriage under furniture and the like.

The second chamber 92 is separated from the third chamber 94 by a partition 194 (cf 15 and 17 ) spatially separated. This partition 194 is positioned on or part of partition 86 . As a result, there is a first area with regard to fluid protection, which is formed by the partition wall 86 and which is oriented transversely to the vertical direction 74 . There is a second area with the wall 194 which is at least approximately parallel to the vertical direction 74 .

The receptacle 186 for a battery device 196 is seated on the second chamber 92. The receptacle 186 for the battery device 196 is open toward the rear side 44. FIG. The battery device 196 can be inserted into the receptacle 186 or removed from it via the rear side 44 . The receptacle 186 extends parallel to the first width direction 70.

An insertion or removal direction 198 for the battery device 196 on the receptacle 186 is parallel to the first width direction 70 (or at most at an acute angle of 30° to this). It is transverse and in particular perpendicular to the second width direction 70.

The insertion/removal direction 198 is transverse and in particular perpendicular to the axis of rotation 134.

It is transverse and in particular perpendicular to the direction 152/opposite direction 162 for the insertion/removal of the cleaning roller 66 from the floor head 22.

The receptacle 186 with the battery device 196 is in the first area 114a (cf 5 ) and is therefore positioned on the bottom head 22 on a different side than the drive motor 104 in relation to the second center plane 112 . Furthermore, an opening 200 of the receptacle 186 faces the rear side 44 and is thus turned away from the cleaning roller 66. This results in protection against splashing water.

In one exemplary embodiment, the receptacle 186 in the area of the rear side 44 is designed in such a way that an operator can access the battery device 196 in order to be able to insert or remove it in the insertion/removal direction 198 and to be able to access it directly.

The second chamber 92 is formed to overhang the receiving chamber 164 for the dirty fluid tank 160 (on the base 82). In particular, the receptacle 186 for the battery device 196 protrudes beyond the receptacle chamber 164 (compare, for example, also 5 ).

The receptacle 186 has an end 202 facing away from the opening 200. If the dirty fluid tank 160 is arranged on the floor head 22, then a portion of the receptacle 186 (and thus also the battery device 196) protrudes over the dirty fluid tank 160; the end 202 meets the dirty fluid tank 160 in its projection in the height direction 74 in the direction of the installation plane 60.

This results in an optimized use of space.

In the floor cleaning device 20, the battery device 196 is positioned on the upper part 84 on the floor head 22 when it is inserted in the receptacle 186, and is thereby positioned in particular above the dirty fluid tank 160 (relative to the vertical direction 74).

The first cover 172, which closes the second chamber 92, forms an upper side of the bottom head 22. It has a recess 204 in the form of a depression. The recess 204 is located at the second center plane 112. The recess 204 provides a depressed area.

The receptacle 186 for the battery device 196 is located next to this recess 204.

The receptacle 186 for the battery device 196 is closer to the first lateral side 76 than to the second lateral side 78.

At and in particular in the recess 204, the joint device 26 is positioned as a holder for the support rod device 24 (cf., for example, 6 ).

The recess 204 as a deepened area results in a small maximum pivoting angle for the pivoting area 58 on the support rod device 24 to the floor head 22. This in turn results in good underride capability.

Also arranged on the recess 204 is a holder 206 for the cleaning roller 66, on which the cleaning roller can be pushed via its carrier 128 for storage or drying (cf 1 ).

In particular, the holder 206 is arranged closer to the rear side 44 than the joint device 26.

In one embodiment, the joint device is at least approximately (at a maximum distance of 5 cm) from the first center plane 110.

In one embodiment, the recess 204 is open to the rear side 44 (cf 6 ).

As a result, for example, water or the like that collects in the recess 204 can flow backwards (towards the rear side 44).

The third chamber 94 is closed by a second cover 208 . This cover 208 (compare 2 ) is removably held (by an operator) on the floorhead 22.

In one embodiment, a hair pin device 214 is arranged in the third chamber 94 and is used to hold hair.

The hairpin device 214 is releasably positioned in the third chamber 94 .

To clean the bottom head 22, an operator can remove the second cover 208 and remove the hair pin assembly 214 to clean it.

The third chamber 94 is positioned above the cleaning roller 66 with a partial area 216 in relation to the vertical direction 74 so that the hairpin device 214 can act on the cleaning roller 66 .

The receiving chamber 164 for the dirty fluid tank 160 is arranged on or in the first chamber 90 on the lower part 82 of the floor head 22 . It is arranged directly adjacent to the receiving shaft 126 for the cleaning roller 66 in the first width direction 70 . Dirty fluid is detached from the cleaning roller 66 (from its cleaning material 130) via a scraper device 210 with at least one scraper strip 212. This can be coupled directly into the dirty fluid tank 160 via a corresponding orifice device 218 on the dirty fluid tank 160 .

In one embodiment, it is provided that the wiper device 210 is seated on the hairpin device 214 and is positioned on the mouth device 218 (cf 3 ).

The dirty fluid tank 160 extends in a first tank width direction 220 and a second tank width direction 222, which is transverse and in particular perpendicular to the first tank width direction 220 (cf 10 ). When the dirty fluid tank 160 is seated on the bottom head 22, the first tank width direction 220 is parallel to the first width direction 70 and the second tank width direction 222 is parallel to the second width direction 72. In the following, therefore, directions are related to the first width direction 70, 72 when the dirty fluid tank is seated on the bottom head 22.

The dirty fluid tank 160 has a first area 224 and a second area 226 (see, for example, FIG 5 ).

The opening device 218 is at the second area 226 and the dirty fluid is coupled from the cleaning roller 66 into the dirty fluid tank 160 via the second area 226 .

The second area 226 of the dirty fluid tank 160 has a greater width in the second width direction 72 than the first area 224 of the dirty fluid tank 160. The width of the second area 226 in the second width direction 72 essentially corresponds to the corresponding length of the cleaning roller 66 along the axis of rotation 134.

The dirty fluid tank 160 has an L-shape (cf 5 ) having a first arm 228 and a second arm 230. The first arm 228 is formed by the second portion 226. The second arm 230 is formed by the first area 224 . The second arm 230 is transverse and in particular perpendicular to the first arm 228.

There is a clearance 232 between the second area 226 and the first area 224 .

When the dirty fluid tank 160 is positioned in the receiving chamber 164 of the floor head 22 , this free space 232 is delimited in the first width direction 70 by the second area 226 and in the second width direction 72 by the first area 224 .

The free space 232 is a partial space in the first chamber 90. It is no longer part of the receiving chamber 164 and is located in particular behind the partition wall 168 (cf 10 ). The drive motor 104 is positioned in the free space 232 .

The first face 106 of the drive motor 104 (when the dirty fluid tank 160 is positioned on the floor head 22 ) faces the first region 224 of the dirty fluid tank 160 . A partial area of the second area 226 is arranged between the drive motor 104 and the cleaning roller 66 (in relation to the first width direction 70).

The first area 224 and the second area 226 of the dirty fluid tank 160 are connected to one another and in particular are connected to one another in one piece and form a common holding volume. The first area 224 and the second area 226 are geometric areas on the dirty fluid tank 160.

The dirty fluid tank 160 has a finger, so to speak, via the second region 226, which can dip into the space between the drive motor 104 and the cleaning roller 66 when positioned on the receiving chamber 164 (cf 10 ).

This results in an optimized use of space and coupling of dirty fluid to the cleaning roller at the mouth device 218 is possible over a large length area at the second area 226 .

Furthermore, this results in a high volume for receiving dirty fluid in the dirty fluid tank 160, even with optimized use of space.

The dirty fluid tank 160 has a basin area 234 and a lid area 236 (cf 15 ).

With the protective fluid tank 160 removed from the bottom head 22 , the cover portion 236 can be removed from the basin portion 234 .

The pelvic area 234 has the L-shape described above with the first area 224 and the second area 226.

The cover area 236 can be designed in one piece or in multiple pieces. For example, the lid area follows the L-shape of the base area 234 in a one-piece design and can be removed as a whole.

For example, in the case of a multi-part design, the cover area includes a part that is firmly connected to the base area 234 and a further part that can be removed.

This detachable part can be used to remove dirty fluid from the dirty fluid tank via the cover area 236 and the dirty fluid tank 160 can be cleaned.

In one embodiment, the first region 224 has a width (up to the second region 226) in the first width direction 70 that is greater than a width of the second region 226 in the first width direction 70 (see, for example 10 ). In particular, a maximum width of dirty fluid tank 160 in second width direction 72 corresponds to a maximum width of second area 226 in second width direction 72.

A maximum width of the dirty fluid tank in first width direction 70 corresponds to the sum of a width of first area 224 and of second area 226 in first width direction 70.

It is provided in particular that a width of the second region 226 in the second width direction 72 is at least 60% and in particular at least 70% and preferably at least 80% of an overall width of the bottom head 22 in the second width direction 72. This results in a high absorption volume for dirty fluid.

Furthermore, it is advantageously provided that a width of the second region 226 in the second width direction 72 is at least 1.5 times, in particular at least 2 times and in particular at least 2.5 times the width of the first region 224 in the second Width direction is 72. This results in a compact construction of the bottom head 22 with a high capacity of the dirty fluid tank with a space-saving construction.

With the dirty fluid tank 160 held on the floor head 22 in the receiving chamber 164 , the drive motor 104 is positioned between the torque transfer device 118 and the first region 224 of the dirty fluid tank 160 .

The free space 232 has an at least approximately hollow cuboid shape.

The receptacle 186 for the battery device 196 protrudes over the first area 224 of the dirty fluid tank 160.

The length of the mouth device 218 in the second width direction 72 is preferably at least 80% of the length of the cleaning roller 66 in the second width direction 72 and preferably extends over its entire length in order to enable optimized coupling.

A diagonal (diagonal plane) 250 can be assigned to the bottom head 22 (cf. 5 ). This diagonal plane 250 is a diagonal plane to the first midplane 110 and the second midplane 112; the diagonal plane 250 lies at an angle of 45° to the mentioned center planes 110, 112 (cf. 5 ).

The diagonal plane 250 goes through the line of intersection of the mentioned center planes 110, 112.

In one embodiment (cf. 5 ) the receptacle 186 for the battery device 196 and the battery device 196 lies on this diagonal plane 250. Furthermore, that region of the torque transmission device 118 on which the output element 122 is seated lies on this diagonal plane 250.

Furthermore, the drive motor 104 lies on this diagonal plane 250. This results in an optimized weight distribution on the floor head 22.

The receiving chamber 184 is designed in such a way that the dirty fluid tank 160 can be pushed in and removed from it in the manner of a drawer and is also held in this way.

The dirty fluid tank 160 can be removed or inserted on the first lateral side 76 . The receiving chamber 164 has an opening 238 for the dirty fluid tank 160 on the first lateral side 76 (compare, for example, 17 or 3 ).

An insertion/removal direction 240 (cf. e.g 3 ) of the dirty fluid tank 160 on the receiving chamber 164 and thus on the bottom head 22 is oriented transversely to the first width direction and in particular oriented perpendicularly thereto. The insertion/removal direction 240 is oriented at least approximately parallel to the second width direction 72 .

It is positioned transversely and in particular perpendicularly to the insertion/removal direction 198 for the battery device 196 .

The insertion/removal direction 240 is oriented at least approximately parallel to the direction 152/opposite direction 162 for inserting or for removing the cleaning roller on the receiving shaft 126.

The cleaning roller 66 and the dirty fluid tank 160 can be removed on the same first lateral side 76 .

It is provided that the dirty fluid tank 160 and the cleaning roller 66 can be used or removed independently of one another, so that it is not necessary, for example, for the cleaning roller 66 to be removed first in order to remove the dirty fluid tank or vice versa.

A housing element 242 is arranged on the dirty fluid tank 160 and, when the dirty fluid tank is inserted, ensures a flush transition to a housing of the bottom head 22 on the first lateral side 76 .

In one exemplary embodiment, a handle element 244 is arranged on the housing element 242 to enable access by an operator.

Furthermore, a fixing device 246 is arranged on the housing element 242, via which the dirty fluid tank can be fixed on the receiving chamber 164 in relation to the insertion/removal direction 240. For example, the fixing device 246 is designed as a form-fit device or snap connection.

In one exemplary embodiment, a sweeping device 248 is arranged on the dirty fluid tank 160 , which is arranged in particular on the second area 226 and extends along the second width direction 72 .

It is the task of the sweeping device 248 to feed coarse dirt from the floor 30 to be cleaned to the cleaning roller 66 so that it can be taken along and coupled into the dirty fluid tank 160 .

The receiving chamber 164 for the dirty fluid tank 160 is open towards the installation level 60 at least in a partial area. As a result, the sweeping device 248 in the dirty fluid tank 160 can act on the surface of the floor 30 to be cleaned.

In one exemplary embodiment, it is envisaged that the dirty fluid tank is held in a floating manner on the receiving chamber 164 .

• Für einen Reinigungsbetrieb des Bodenreinigungsgeräts 20 wird dieses von der Bodenstation 64 entnommen. Bei dem in 1 dargestellten Zustand wird der Deckel 144 entnommen und es wird die Reinigungswalze 66 in den Aufnahmeschacht 126 gebracht und es wird der Deckel 144 geschlossen. Dies kann dadurch erfolgen, dass zuerst die Reinigungswalze 46 in den Aufnahmeschacht 126 gebracht wird und dann der Deckel 144 auf die Reinigungswalze 66 und den Bodenkopf 22 aufgesetzt wird, oder indem zunächst die Reinigungswalze 66 auf das zweite Drehlager 128 (Widerlager) an dem Deckel 144 aufgesetzt wird und dann eingeschoben wird und für eine Fixierung des Deckels 144 an dem Bodenkopf gesorgt wird.

The floor cleaning device 20 works as follows:

• The floor cleaning device 20 is removed from the floor station 64 for a cleaning operation. At the in 1 In the state shown, the cover 144 is removed and the cleaning roller 66 is brought into the receiving shaft 126 and the cover 144 is closed. This can be done by first bringing the cleaning roller 46 into the receiving shaft 126 and then placing the cover 144 on the cleaning roller 66 and the bottom head 22, or by first placing the cleaning roller 66 on the second pivot bearing 128 (abutment) on the cover 144 is placed and then pushed in and fixing of the cover 144 to the bottom head is ensured.

When the dirt fluid tank is inserted, a cleaning process can be carried out on the floor 30 to be cleaned.

An operator can make an adjustment accordingly via the pivoting position of the support rod device 24 on the joint device 26 .

Cleaning liquid is supplied from the cleaning liquid tank 50 to the nozzle device 180 via the guide device 178 and the cleaning roller 66 is moistened. Alternatively or additionally, the floor 30 to be cleaned can also be moistened directly.

The drive motor is supplied with electrical energy via the battery device 196 . It drives a rotation of the cleaning roller 66 about the axis of rotation 134 via the output element 122 . This acts mechanically on the floor 30 to be cleaned and loosens dirt. This is taken along and detached via the wiper device 210 and coupled into the dirty fluid tank 160 via the outlet device 218 . Hair is picked up via the hair pin device 214 .

If the dirty fluid tank 160 is filled (which is displayed in particular on the floor cleaning device 20) or if the cleaning before gang is finished, then the dirty fluid tank 160 is taken and emptied and cleaned if necessary.

By opening the second cover 208, the hairpin device 214 (with the wiper device 210) can be accessed and removed and cleaned.

The cleaning roller 66 can be removed and inserted into the holder 206 when the floor cleaning device 20 is parked at the floor station 64 .

The support bar assembly 24 is placed in the park position 62 .

The floor cleaning device 20 has a compact design. The floor head is designed to save space. The L-shape of the dirty fluid tank 160 results in an optimized use of space with a large capacity and, in particular, the ability to couple dirty fluid from the cleaning roller 66 via the opening device 218 into the dirty fluid tank without a fan.

The arrangement of the drive motor 104 and the battery device 196 on both sides of the second center plane 112 results in a torque balance. The arrangement of the battery device via the receptacle 186 results in optimized splash protection (due to the arrangement facing away from the cleaning roller 66) and by the Arrangement above the partition wall 86.

The partition wall 86 enables a simple construction with optimized protection of moisture-sensitive areas such as the circuit 174 and the solenoid valve 176.

The cleaning roller 66 is mounted on two sides via the pivot bearing device 132, namely via the first pivot bearing 136 and the second pivot bearing 138, which are spaced apart from one another in the second width direction 72. As a result, the cleaning roller 66 can be designed with a great length and an optimized cleaning result is obtained.

The second pivot bearing 138 as an abutment for the first pivot bearing 136 is arranged on a removable cover 144 . This makes it easy to remove and insert the cleaning roller 66.

The cover 144 is part of the bottom head 22, and the cleaning roller 66 can be removed from this.

The cleaning roller 66 (without cover 144) can be cleaned in a washing machine in particular.

A floor cleaning device 20 was described above as an exemplary embodiment, which is hand-held and in particular by a standing user.

The embodiment has been described as a floor cleaning device 20 which is fan-free. In principle, it is also possible for a blower device to be provided in order to suck off the cleaning roller 66 (and optionally also the floor 30 to be cleaned). The blower assembly may be located on the support rod assembly 24, or may be located on the floorhead 22.

It is possible that the solution according to the invention (pivot bearing device with first pivot bearing and abutment, L-shape of the dirt tank, chamber structure with splash-proof partition wall and more in combination or individually) is also used on a self-propelled and self-steering floor cleaning device (“cleaning robot”).

The design is basically the same as described above, without the support rod device 24, in which case corresponding sensor elements and a device for self-propelling and self-steering are also present.

The self-propelled and self-steering floor cleaning device can be designed without a fan or be provided with a fan device, which is then naturally arranged on the corresponding floor head.
