The at least one cassette is positioned removably on the cleaning head by a holding device for the at least one cleaning roller. The holding device has at least two spaced-apart holding points for the at least one cleaning roller, by means of which the at least one cleaning roller is held detachably on the at least one cassette when the at least one cassette is removed from the cleaning head, and when the at least one cassette is arranged on the cleaning head, the at least one cleaning roller is coupled to the at least one drive shaft in a torque-effective manner.The object of the invention is to provide a floor cleaning appliance of the type mentioned at the beginning which has extensive cleaning modes.This object is achieved according to the invention in the case of the floor cleaning appliance mentioned at the beginning in that the at least one cleaning roller can be removed from the at least one cassette when at least one cassette is fixed to the floor head via the fixing device and can be removed from the floor head.In the solution according to the invention, it is possible to remove only the cleaning roller from the bottom head, wherein the at least one cassette remains on the bottom head.As a result, for example, an effective cleaning of the floor cleaning appliance itself (after a cleaning operation on a surface to be cleaned) can be realized. For example, the at least one cleaning roller can then be removed from the floor head in order to clean or replace it separately. The separate cleaning of the at least one cleaning roller can be carried out, for example, in a washing machine.The remaining cassette can be cleaned with the bottom head, for example at a cleaning station. As a rule, the at least one cassette has to be cleaned less often or less intensively than the at least one cleaning roller.Advantageously, there is also the possibility of removing the at least one cassette with at least one cleaning roller held thereon from the floor head. This makes it possible, for example, to remove it by an operator without having to grasp the at least one cleaning roller.It is advantageous if the holding device has a holding element for the at least one cleaning roller, wherein, when the at least one cassette is fixed to the base head, the at least one cleaning roller can be removed from the cassette or a removability can be released by a relative movement of the holding element and the at least one cleaning roller. During a cleaning operation of the floor cleaning appliance, the at least one holding element has a holding function for the at least one cleaning roller on a surface to be cleaned. The relative movement of the at least one cleaning roller and the holding element allows the cleaning roller to be removed from the cassette or access to the at least one cleaning roller is enabled, so that the cleaning roller can in turn be removed from the floor head, even if the at least one cassette is still fixed to the floor head.In particular, during a cleaning operation of the floor cleaning appliance with at least one cleaning roller rotating about the axis of rotation, the at least one cleaning roller is held on the holding device via the holding element. The at least one holding element has a holding function for the at least one cleaning roller for a cleaning operation of the floor cleaning appliance.In a structurally favorable embodiment, the holding element has a pivot bearing for the driven rotation of the at least one cleaning roller. This results in a constructionally simple construction of the floor cleaning appliance with the driven at least one cleaning roller.It is structurally favorable if the at least one holding element is arranged movably relative to the at least one cassette. As a result, the at least one cleaning roller can be released or removed in a simple manner in order to be able to remove it directly from the floor head, even if the at least one cassette remains on the floor head.It is then particularly advantageous if the holding element is seated movably or detachably on the floor head. By moving the holding element, the at least one cleaning roller is released in order to be able to remove it from the floor head. The holding element can remain connected to the base head or be completely removable.It is very particularly advantageous if a receiving shaft for the at least one cassette is arranged or formed on the bottom head, wherein the receiving shaft is closed on one side by an openable cover, and the holding element is positioned in the region of the cover or on the cover. This results in a constructionally simple construction.The at least one cleaning roller can also be rotatably held on the floor head in the manner of a clamping between the holding element and a counter element. Opening the cover results in simple access to remove the at least one cleaning roller.It is particularly advantageous if a receiving shaft for the at least one cassette is arranged or formed on the bottom head and an openable cover is assigned to the receiving shaft. As a result, the at least one cleaning roller can be removed from the base head in a simple manner. Furthermore, the at least one cassette can be removed in a simple manner. This results in the at least one cleaning roller accessing a surface to be cleaned downward. The receiving shaft is laterally closed by the openable cover.In one embodiment, a holding element of the holding device is seated on the cover. This holding element comprises in particular a pivot bearing. As a result, with a constructionally simple construction, the at least one cleaning roller can be rotatably held on the base head. This results in a relatively large cleaning width for the floor cleaning appliance.It can then be provided that the at least one cleaning roller can be removed by removing the cover from the at least one cassette when the latter is fixed to the base head. The at least one cleaning roller is then connected to the cover in such a way that by removing the cover, the at least one cleaning roller is carried along and is thereby removed from the at least one cassette and thus in turn from the base head.It is alternatively or additionally possible that, when the cover is open, the at least one cleaning roller is accessible such that it can be removed from the at least one cassette when the at least one cassette is fixed to the base head. By opening the cover, a corresponding access is then made possible in order to remove the at least one cleaning roller from the at least one cassette and thus from the base head.In one embodiment, it is provided that the retaining element is seated detachably on the floor head. The holding element can be its own element or can be arranged, for example, on a removable cover for a receiving shaft.It is then particularly advantageous if the holding element is removable relative to the at least one cassette. The holding element is basically an element of the holding device and contributes to the fact that the at least one cleaning roller is held on the at least one cassette in a correspondingly rotatable manner during a cleaning operation. By being able to be removed relative to the at least one cassette, the at least one cleaning roller can be released in order to be able to remove it from the cassette. It is possible that the holding element is detachably fixed to the at least one cassette, or fixed to a cassette holder on which the cassette is held, or fixed to the bottom head (outside the cassette or the cassette holder). Mixed forms are also possible. If the holding element is seated on the at least one cassette or on a cassette holder, then the holding element can "participate" a movement of the at least one cassette relative to the base head, for example during a cleaning operation. It can be provided, for example, that the at least one cassette is movably mounted on the bottom head via a movable cassette holder. In this connection, reference is made to the non-prepublished German patent application No. 10 2024 103 726.1, dated 9 February 2024.In particular, in one exemplary embodiment, the holding element is an element separate from a cover of a receiving shaft for the at least one cassette. It is then removable as such from the bottom head (and also from the lid). This results in a constructionally simple construction. The holding element and the cover can be optimized separately. For example, the holding element can then also be assigned an additional function, such as a protective wall function for an operating unit on the at least one cassette.It is advantageous if the holding element, if it is fixed relative to the at least one cassette, covers an operating element for releasing the fixing of the at least one cassette to the floor head. For example, the at least one cassette is seated fixed to the base head via a pressure snap-in device. By applying pressure to the cassette, it can be released from the bottom head. If the holding element is seated with respect to the cassette in such a way that no corresponding compressive force can be exerted on the cassette in order to release the fixing or via the pressure snap-in device, a corresponding protective effect is provided. Unintentional detachment of the at least one cassette is not possible when the holding element is fixed accordingly. The at least one holding element can be seated on the at least one cassette itself for this covering function, or on a cassette holder for the at least one cassette, or also on the base head. Combination forms are also possible, such as for example the holding element being fixed both to the cassette and to the cassette holder.It is particularly advantageous if, in addition to the individual removability of the at least one cleaning roller from the cassette, when the latter is fixed to the base head, the at least one cassette with held at least one cleaning roller is also removable from the base head and, in particular, when the at least one cassette is removed from the base head and has held at least one cleaning roller, the at least one cleaning roller is removable from the at least one cassette. This results in at least two options for an operator to remove the at least one cleaning roller from the floor head.In one embodiment, it is provided that the at least one cleaning roller is removable from the at least one cassette when it is fixed to the base head in a removal direction which is parallel to a removal direction of the at least one cassette from the base head. This results in a constructionally simple construction.It is then particularly favorable if a removal direction of the at least one cleaning roller from the base head is at least approximately parallel to the axis of rotation of the at least one cleaning roller. As a result, the bottom head can be realized in a constructionally simple manner.It can also be provided that the at least one cleaning roller can be removed from the at least one cassette, when it is fixed to the floor head, with at least one of the following:the at least one cleaning roller can be removed via an underside of the floor head, wherein the underside faces a placement plane of the floor head on a surface to be cleaned;the at least one cleaning roller can be removed via the opening of a receiving shaft for the at least one cleaning roller, wherein the opening faces a placement plane.As a result, the at least one cleaning roller can be removed downward, for example at a cleaning station.It is then favorable if the at least one cleaning roller can be removed from the at least one cassette by way of a pivoting movement, when the latter is fixed to the floor head. This results in a simple removability of the at least one cleaning roller from the at least one cassette.It can be provided that the at least one cassette can be removed from the floor head in a removal direction parallel to a placement plane of the floor head. This results in a constructionally simple design of the bottom head.Alternatively, it is also possible for the at least one cassette to be removable from the floor head with a directional component transverse to a placement plane of the floor head. It can then be removed, for example, via an underside of the floor head.It is advantageous if the at least one cassette is held on the bottom head via a cassette holder, wherein in particular the cassette holder is movably seated on the bottom head. A simple fixing to the bottom head can be achieved by means of the cassette holder. By way of a movable cassette holder, for example, additional pressure can be exerted by the at least one cleaning roller on a floor to be cleaned. As a result, wear of a covering of the at least one cleaning roller can be compensated for, for example, or an additional contact pressure can be provided during the cleaning process. The corresponding mobility can also be advantageous, for example, for cleaning the floor cleaning appliance itself, i.e., a cleaning station.It is advantageous if at least one of the following is provided:a drive motor for the at least one cleaning roller;a moistening device for providing cleaning liquid to the at least one cleaning roller;a scraping device for scraping dirt fluid from the at least one cleaning roller, which is arranged in particular on the at least one cassette;a tank device for dirty fluid, which is seated in particular detachably on the floor head;the at least one cleaning roller has a textile covering.The moistening device can wet the at least one cleaning roller, in particular with the cleaning liquid from a corresponding tank device. This results in improved soil releasability for hard soils.By means of the scraping device, dirt fluid can be scraped off the at least one cleaning roller (in a cleaning operation of the floor cleaning appliance). The scraped dirty fluid can be coupled into a tank device for dirty fluid.It is advantageous if the at least one cleaning roller has a textile covering and in particular microfiber covering. As a result, hard soils in particular can be effectively cleaned.The floor cleaning appliance according to the invention is designed in particular to be self-propelled and self-steering (designed as a cleaning robot). The floor cleaning appliance advantageously has a wet wiping function via the at least one cleaning roller. Additionally or alternatively, a dry cleaning function may be provided.According to the invention, it is provided that in a cleaning station of the type mentioned at the beginning, a movable arm is provided with an engagement region on the at least one cleaning roller or on a holding element for the at least one cleaning roller, wherein the at least one cleaning roller can be removed from the floor cleaning appliance via the movable arm when the floor cleaning appliance is positioned at the cleaning station and the at least one cassette is fixed to the floor cleaning appliance.The at least one cleaning roller can be removed automatically at the cleaning station via the movable arm. This is then provided separately from the bottom head. It can then be cleaned separately, for example by a user, such as in a washing machine. At the cleaning station, the floor cleaning appliance with the at least one cassette can be effectively cleaned when the at least one cleaning roller is removed.In particular, the movable arm is assigned a movement axis which is parallel to the rotation axis of the at least one cleaning roller. As a result, the at least one cleaning roller can be effectively removed from the base head and optionally also reinserted.According to the invention, a cleaning station for a floor cleaning appliance according to the invention is also provided, which cleaning station comprises a movable transport device having a receptacle for the at least one cleaning roller, wherein the movable transport device has at least one first position for receiving the at least one cleaning roller in the receptacle and has a second position for bringing the at least one cleaning roller received by the receptacle into a receiving space.The movable transport device allows the at least one cleaning roller to be transported from the base head into the receiving space of the cleaning station.In particular, the movable transport device can support or carry out detachment of the at least one cleaning roller from the floor head. A relative movement of the at least one cleaning roller to the base head can basically be achieved via the transport device with a detachment function for the at least one cleaning roller from the base head and a corresponding transport function.It is advantageous here if the receiving space is positioned below the floor cleaning device when the floor cleaning device is set up on the cleaning station. This results in a compact structure of the cleaning station.It is furthermore advantageous if a receiving chamber with the receiving space is provided, wherein the receiving chamber has an opening between an adjusting device for the floor cleaning appliance and the receiving space, wherein the at least one cleaning roller can be brought through the opening after being released from the floor cleaning appliance into the receiving space of the cleaning station. This results in a transportability of the at least one cleaning roller into the receiving space with a structurally simple structure of the cleaning station. For example, a plurality of cleaning rollers can be accommodated in the accommodation space, which can then be cleaned together (for example in a washing machine) itself. The cleaning station can be implemented compactly in this case. in particular, automated detachment of cleaning rollers from the floor head can be implemented.For the same reason, it is favorable if the transport device is positioned movably in the opening at least with its receptacle. As a result, a cleaning roller can be moved from the floor head on the floor cleaning appliance through the opening into the receiving space.In a structurally favorable embodiment, the transport device with the receptacle is positioned pivotably at the cleaning station. Due to the corresponding mobility (pivot mobility) of the receptacle, a cleaning roller can be moved from the bottom head of the floor cleaning appliance into the receptacle space.According to the invention, the combination of a cleaning station according to the invention with a floor cleaning appliance according to the invention is provided.The following description of preferred embodiments serves to explain the invention in more detail in conjunction with the drawings.

Wheels 16 are seated on the floor head body 14. The floor cleaning appliance 10 is driven with its floor head 12 in a self-propelled manner via these wheels 16. A wheel axle 18 is associated with the wheels 16. A forward travel direction 20 of the floor cleaning appliance 10 during a cleaning process on a surface 22 to be cleaned is transverse and in particular perpendicular to the wheel axis 18.Furthermore, a pivotable roller 24 is seated on the floor head body 14 at a distance from the wheels 16.A placement plane 26 for the floor head 12 on the surface 22 to be cleaned is defined by the wheels 16 and the roller 24. When the surface 22 to be cleaned is flat, this placement plane 26 coincides with the surface 22 to be cleaned.The floor head 12 is provided with a navigation device 28.The bottom head body 14 has a bottom 30 and a top 32 and is provided with a receiving chute 34 for a cleaning roller 36. The receiving shaft is open to the underside 30 of the floor head 12, which faces the placement plane 26.In one embodiment, the receiving well 34 is also open to a lateral side 38 of the floor head 12 via an opening 40 (see, for example, FIG. 4 ). An openable cover 43 is provided for closing the opening 40.The cleaning roller 36 is mounted on a cassette 42 having a holder 44 on the bottom head body 14. The cassette 42 can be detachably fixed to a cassette holder 48 of the bottom head body 14 via a fixing device 46.A drive 50 for the cleaning roller 36 is seated on the bottom head body 14 for its rotational drive (when the cleaning roller 36 is seated on the cassette 42 and the cassette 42 is fixed to the bottom head body 14 via the cassette holder 48 and the fixing device 46).The drive motor 50 is assigned a driver 52 (FIG. 5 ), which projects into the receiving shaft 34 on a side facing away from the opening 40.An axis of rotation 54 for the rotation of the cleaning roller 36 during a cleaning operation (driven via the drive motor 50) is parallel to the wheel axis 18, which is transverse and in particular perpendicular to the forward travel direction 20.In one embodiment, the cleaning roller 36 comprises a textile trim.The cleaning roller 36 protrudes beyond an opening of the receiving shaft 34, which opening faces the placement plane 26, toward the placement plane 26 and contacts the placement plane 26 during a cleaning process.In one embodiment, the cassette holder 48 is movable and, for example, pivotably mounted and, in particular, spring-supported. As a result, during a cleaning process, the cleaning roller 36 can be pressed against the placement plane 26 and, for example, wear of the cleaning roller 36 can also be compensated accordingly.The bottom head body 14 is detachably mounted with a dirty fluid tank 56. Dirty fluid from the cleaning roller 36 is coupled into this tank device 56, in particular without suction fan.On the bottom head body 14, there is further detachably mounted a cleaning liquid tank means 58. The cleaning liquid is in particular clean water, optionally with a surfactant additive of cleaning agent.A moistening device 60 is provided, which is fluidically coupled to the tank device 58 for cleaning liquid.The moistening device 60 comprises a liquid feed 62 on the cassette 42 (FIG. 8 ), via which cleaning liquid on the cassette 42 can be fed to the cleaning roller 36 via nozzles on the cassette 42 for a cleaning operation.The cartridge 42 further includes a scraper device 64 (FIG. 8 ) that serves to strip and drain dirty fluid from the cleaning roller 36. The scraping device 64 comprises a corresponding scraping strip, which in particular serves a textile material of the cleaning roller for improved scraping of dirty fluid during a cleaning process.Furthermore, a mouth device 66 (FIG. 8 ) is arranged on the cassette 42. By means of this, scraped-off dirty fluid can be coupled from the cleaning roller 36 into the tank device 56 for dirty fluid.The holding device 44 of the cassette 42 comprises a holding element 68 with a pivot bearing 70 for rotation about the axis of rotation 54. When the cleaning roller 36 is positioned on the base head body 14, the cleaning roller 36 is suspended, to a certain extent, between the pivot bearing 70 of the holding element 68 and the driver 52.The holding element 68 is seated in the region of the cover 43.The holding device 44 comprises a further holding element 72 facing away from the holding element 68, which further holding element 72 serves, in combination with the holding element 68, to hold the cleaning roller 36 on the holding device 44 (on the cassette 42). The further holding element 72 does not absorb any torque during operation of the floor cleaning appliance 10 with rotation of the cleaning roller 36. It serves for a type of prepositioning of the cleaning roller 36 on the holding device 44.The holding element 68 with the pivot bearing 70 is assigned to the opening 40 and in particular to the cover 43. In an embodiment (FIGS. 1, 2, 3, 4, 5, 6, 7, 8, 9-10), the retaining member 68 is seated on the lid 43.In this exemplary embodiment, the cover 43 with the holding element 68 (and thus the pivot bearing 70) can be removed from the base head body 14.As a result, the cleaning roller 36 can be removed from the cassette 42, even if the cassette 42 is fixed to the floor head body 14 via the fixing device 46.It is basically the case here that the cleaning roller 36 can be removed from the base head body 14 (from the holding device 44 of the cassette 43) as the cover 43 is removed (compare for example FIG. 3 ), or that the cover 43 with the holding element 68 can be removed from the base head body 14, and the cleaning roller 36 remains on the cassette 42 in the process, and the cleaning roller 36 can subsequently be removed from the cassette 42. Both possibilities can be realized on the same floor cleaning device.The floor cleaning appliance 10 functions as follows:In a cleaning operation, the cassette 42 with the cleaning roller 36 held thereon is positioned in the receiving shaft 34 and the cover 43 is closed. The cleaning roller 36 is connected to the driver 52 in a torque-effective manner and is coupled to the pivot bearing 70 of the holding element 68 (FIGS. 1, 2 ).During a cleaning operation, the floor head 12 travels over the surface 22 to be cleaned.Driven via the drive motor 50, the cleaning roller 36 rotates about the axis of rotation 54; it is moistened with cleaning liquid from the tank device 58 via the moistening device 60. In order to convey cleaning liquid from the tank device 56, a pump is provided in particular, which is positioned on the bottom head body 14.The cleaning roller 36 acts on the surface 22 to be cleaned with a corresponding mechanical load due to the rotation. The dissolution of dirt is improved by the application of liquid. Dirty fluid is received by the cleaning roller 36. The cleaning roller 36 rotates past the stripper means 64 (which is mounted on the cassette 42). Dirt fluid is removed from the textile covering of the cleaning roller 36 via the scraping device 64 and fed to the opening device 66. From there, it is conveyed into the dirty fluid tank device 56.In the solution according to the invention, when the cassette 42 is fixed to the base head body 14, the cleaning roller 36 is removable (compare FIGS. 3, 4 ). As a result, a separate cleaning of the cleaning roller 36 can be carried out, for example, in a washing machine with the cassette 42 remaining on the floor head body 14. It is possible, for example, to perform an effective cleaning of the cassette 42 (for the cleaning of the floor cleaning appliance 10 itself) at a cleaning station. The cleaning roller 36 can be cleaned separately by removing it from the floor head body 14.For this purpose, the opening 40 is opened via the cover 43 (FIG. 3 ).In the exemplary embodiment shown, by a corresponding, for example press-fit, fixing of the cleaning roller 36 to the cover 43, the latter is carried along and pulled out of the receiving shaft 34.A removal direction 74 (FIG. 3 ) is parallel to the corresponding removal direction of the lid 43. the removal direction 74 is at least approximately parallel to the axis of rotation 54.As a result, the lid 43 is then removed and the cleaning roller 36 is removed from the bottom head body 14. The cartridge 42 remains on the bottom head body 14 (see FIG. 4 ). In this described variant, when the cover 43 is removed, the cleaning roller 36 is released from the holding device 44 of the cassette 42 and pulled out of the receiving shaft 34 via the corresponding movement of the cover 43.It is also possible for the cover 43 to be initially released from the base head body 14 and for the holding element 68 to also be released from the base head body 14.This can possibly be further aided if a corresponding force is exerted on the cleaning roller 36, for example from the underside 30, in order to bring about the detachment of the cover 43 from the cleaning roller 36 (detachment of the retaining element 68 from the cleaning roller 36).FIG. 5 shows a bottom view of the bottom head body 14 after the cleaning roller 36 has been released, with the cassette 42 further fixed by means of the fixing device 46.The cassette 42 itself is detachable from the base head body 14 in a removal direction 76 (FIG. 6 ).In the embodiment shown, the direction 76 of removal of the cassette 42 from the bottom head body 14 is parallel to the direction 74 of removal of the cleaning roller 36 from the cassette 42.Removal of the cassette 42 from the base head body 14 can be useful, for example, for further cleaning of the cassette 42.In FIG. 7, the same view as FIG. 5 is then correspondingly shown, with the cassette 42 then also being removed. The receiving shaft 34 on the bottom head body 14 is then empty.In the exemplary embodiment in which the cleaning roller 36 with the cover 43 is removed from the base head body 14 (compare FIG. 9 ), the cleaning roller 36 can then be released accordingly from the holding element 68 on the cover 43 by sufficient force exertion.FIG. 11 shows an exemplary embodiment of a floor cleaning appliance 10, which is basically designed like the floor cleaning appliance 10. Seated on the cover 78 is a corresponding holding element 80 with pivot bearing 82, When the cover 78 (FIG. 11 ) is open, which is correspondingly pivoted about a pivot axis 84, wherein the pivot axis 84 is transverse and in particular perpendicular to the placement plane 26, the receiving shaft 34 is accessible at the opening 40. The cleaning roller 36 can be accessed. This can then be pulled out of the receiving shaft 34 automatically or manually by being detached from the cassette 42.In this embodiment, the lid 78 is a non-detachable element on and remains on the bottom head body 14. The cover 78 and thus also the holding element 80 is movably positioned on the floor head body 14, i.e. is movably seated on the floor head body 12.In another embodiment (FIG. 12 ), a removable lid 86 is provided on the bottom head body 14. This cover 86 comprises a holding element corresponding to the holding element 68 with pivot bearings. When the cover 86 is removed, the corresponding holding element with the pivot bearing is also removed. The receiving shaft 34 with the cleaning roller 36 is accessible at the opening 40. The cleaning roller 36 can be removed from the cartridge 42 with the cartridge remaining on the bottom head body 14.A cleaning station 88 is assigned to the floor cleaning appliance 10 (FIGS. 13, 14 ). The floor cleaning appliance 10 generally soils during a cleaning operation. The cleaning station 88 serves for cleaning the floor cleaning appliance 10 itself (outside a cleaning operation on the surface 22 to be cleaned).The cleaning station 88 can fulfil further tasks, such as, for example, charging a battery device of the floor cleaning appliance 10, receiving dirty fluid from the tank device 56, providing cleaning liquid for the tank device 58 and cleaning the receiving shaft 34 (see below). For this purpose, the cleaning station 88 has, in particular, corresponding devices and superstructures, which are not shown in FIGS. 13 and 14.In one embodiment, the cleaning station 88 comprises a placement body 90. the cleaning station 88 can be placed on a base and in particular on a floor via the placement body 90.In one exemplary embodiment, the mounting body 90 is plate-shaped. It has a ramp 92 and a placement plane 94. The floor cleaning appliance 10 can be placed on the placement plane 94 via the ramp 92 and can be placed there.The support body 90 is assigned a specific position of the floor cleaning appliance 10. In this corresponding position 96 of the floor cleaning appliance 10 at the cleaning station 88, the cleaning roller 36 can be removed from the floor head 12 in an automated manner. In the corresponding position 96, the "remaining" floor head 12 can then also be cleaned.The cleaning station 88 comprises a movably arranged arm 98. the arm 98 is positioned in an embodiment such that it can be displaced with respect to the placement body 90.In one embodiment, the arm 98 is seated on a bracket 100. This bracket 100 in turn has a further arm 102, which is spaced apart and in particular spaced apart parallel to the arm 98. In one exemplary embodiment, the further arm 102 is guided on a guide device 104 on the placement body 94. It is assigned a drive for its displacement movement in a direction / opposite direction 106. When the floor cleaning appliance 10 is positioned in the position 96 at the cleaning station 88, this direction 106 is substantially parallel to the axis of rotation 54; it is substantially parallel to the wheel axis 18; it is transverse and in particular perpendicular to the forward travel direction 20; it is parallel to the installation plane 26.The bracket 100 is formed by the arm 98 and the further arm 102, wherein a web 108 is connected to the arm 98 and the further arm 102 and is oriented, for example, perpendicular to this arm 98 and further arm 102.On the arm 98, there is arranged an engagement region 110 for the cleaning roller 36 or the cover 86 (or the holding element 68).In the exemplary embodiment shown in FIGS. 13, 14, the engagement region 110 is designed for engagement with the cleaning roller 36 and, in the process, for end-face engagement with the cleaning roller 36. In this embodiment, the cover 43 is completely detachable.However, it is also possible for the engagement region to be designed for engagement with the cover 43 and for the cleaning roller 36 to be removable from the receiving shaft 34 by removing the cover.By means of the driven movement of the further arm 102 in the direction 106 and engagement of the engagement region 110 with the cleaning roller 36 (or the cover 43), the cleaning roller 36 can be removed from the cassette 42 via the arm 98, and can thereby be removed from the base head 12 (compare FIG. 14 ).This functions as follows:The floor head 12 is moved to the cleaning station 88. The floor head 12 is positioned on the placement plane 94 in its corresponding position 96.In the exemplary embodiment shown, the cover 43 is then opened. (This may also be done automatically by the cleaning station 88.)The arm 98 is then moved on the end face of the cleaning roller 36 and the engagement region 110 couples mechanically to the cleaning roller 36.By driving the arm 98 in the direction 106, the cleaning roller 36 is pulled out of the cassette 42 and thereby out of the receiving shaft 34, thereby being removed from the floor head body 14.In Fig. 14, an intermediate state is shown in which the cleaning roller 36 is not yet fully implemented.When the cleaning roller 36 is completely removed from the floor head body 14, it can be removed by a user and separately cleaned in, for example, a washing machine.The floor cleaning appliance 10 is already correctly positioned at the cleaning station 88 via the position 96 for a cleaning operation. For example, by a corresponding spray action, the floor head 12 can be cleaned on the receiving shaft with the cassette 42 fixed.When the cleaning roller 36 is fixed to the cover 43 via the holding element 68, the cleaning roller 36 is guided out in a similar manner, wherein the engagement region 110 of the arm 98 then couples mechanically to the cover 43.A fresh or cleaned cleaning roller 36 can then be reinserted by the reverse process. It is coupled to the engagement area 110 and, by retracting the arm 98, the cleaning roller 36 is brought into the receiving shaft 34 and positioned on the cassette 42.The arm 98 then moves away from the bottom head 12 and the lid 43 is closed automatically or by an operator.In a further exemplary embodiment of a floor cleaning appliance, which is shown in FIGS. 15, 16, 17, 18, 19, 20, 21, 22 to 23 and is denoted by 120, a floor head 122 is provided. A cover 124 is positioned on the bottom head 122 on an upper side. A cleaning liquid tank means 126 is provided which is positioned on the bottom head 122 below the lid 124. Furthermore, a tank device 128 for dirty fluid is provided (in FIGS. 16, 17 and 21, this tank device 128 is removed).With regard to the functional components, the floor cleaning device 120 is configured similarly or identically to the floor cleaning device 10.On the bottom head 122, a receiving shaft 130 for a cassette 132 is formed with a holding device 134. The holding device 134 rotatably holds a cleaning roller 136 in the receiving tray 130 for a cleaning operation. The receiving well 130 is open laterally on the bottom head 122 via an opening 138. For closing this opening 138, a removable or movable cover is provided (not shown in the drawings).For driving the cleaning roller 136 when it is positioned in the receiving shaft 130, a drive motor 140 (FIG. 20 ) is provided. The cleaning roller 136 has a sleeve which can be plugged onto the drive motor 140. The drive motor 140 is an internal drive motor relative to the cleaning roller 136 when it is positioned in the receiving shaft 130.The drive motor 140 is fixed to the bottom head 122 in a region 142 which faces away from the opening 138.When the cleaning roller 136 is placed on the drive motor 140, a corresponding drive shaft of the drive motor 140 also forms a pivot bearing.The holding device 134 has a holding element 144 which is positioned facing away from the drive motor 140. The holding element 144 in turn has a pivot bearing 146 for rotatably mounting the cleaning roller 136 during the driven rotation.The holding element 144 is seated in the region of the opening 138 or of the cover for the opening 138.The holding element 144 is arranged on the holding device 134 in a manner releasable from the cassette 132. A corresponding fixing device 148 is provided, which enables a detachable fixing of the holding element 144, for example, on the cassette 132 (see below).The cartridge 132 itself is supported on the bottom head 122 via a cartridge holder 150.A detachable axial fixing of the cassette 132 with the holding device on the bottom head 122 is provided in the region of a transverse wall 152. This transverse wall 152 is opposite to the opening 138 on a lateral side opposite the lateral side (on which the opening 138 lies).This corresponding fixing device is designed in an embodiment as a snap-on pressure device. In this connection, reference is made to the non-prepublished German patent application No. 10 2024 103 698.2, dated 9 February 2024, and reference is made in its entirety.It is provided in particular that the holding element 144, when it is seated on the cassette 132, is positioned on the cassette 132 in such a way that an operating element for releasing the fixation is covered with the transverse wall 152.In an example of a snap-on pressure device, the fixing to the transverse wall 152 can be released by applying pressure to the cassette 132 from an end face 154 (compare FIG. 16 ).In one embodiment, the holding element 144 is designed such that it has a region 156 which bears against the cassette holder 150 or has a correspondingly small spacing. The arrangement is such that by applying pressure to the holding element 144 in the direction of the transverse wall 152, in particular due to the contact of the region 156, the corresponding pressure-snap-on device cannot be released.When the retaining member 144 is positioned on the cartridge 132, inadvertent disengagement of the cartridge 132 from the bottom head 122 from the receiving tray 130 is not possible. The retaining element 144 must first be removed.The floor cleaning device 120 functions as follows with respect to the removal of the cleaning roller 136:In an initial state, the opening 138 is closed by an openable lid (not shown in the drawings), or no lid is provided and the receiving chute 130 is always open at the opening 138. For removing the cassette 132, this cover is opened or, in one embodiment, removed. The state according to FIG. 15 is then present.The support member 144, which is an "intermediate member" between the lid and the cartridge 132, is connected to the bottom head 122. It is seated in particular on the cassette 132 and is fixed to the cassette 132 via a holding element fixing device 158 (compare FIG. 18 ).In an exemplary embodiment, a latching hook 160 is provided for this purpose on the holding element 144, which latching hook is movable. The latching hook 160 points toward the cassette 132. An operating element 162 for releasing the latching is accessible from an outer side of the holding element 144 (facing away from the receiving shaft 130).A latching opening for the latching hook 160 is provided on the cassette 132.The holding element 144 is then removed from the bottom head 122 by releasing the holding element fixing device 158. This state is shown in FIG. 16.This removal can be carried out "manually" by an operator, or automatically, for example at a corresponding cleaning station.The cleaning roller 136 can then be pulled out of the cassette 132 and removed from the bottom head 122. A corresponding removal direction 164 is parallel to the axis of rotation of the cleaning roller 136 (see FIG. 17 ).In this embodiment, the lid is first opened, then the holding member 144 is removed from the bottom head 122, and then the cleaning roller 136 is removed from the cartridge 132 which remains fixed to the bottom head 122.The removal of the cleaning roller 136 from the cassette 132 can be carried out manually by an operator or automatically, for example at a cleaning station.The cassette 132 itself can be removed from the bottom head 122. A release takes place at the pressure-snap device and the cassette 132 can be pulled out of the receiving shaft 130 in a direction parallel to the removal direction 164 (compare FIG. 19 ).When the support member 144 is seated against the bottom head 122, and more particularly against the cartridge 132, the portion 156 prevents the cartridge 132 from being detachable. If the cassette 132 is to be removed from the receiving shaft 130 in the removal direction 164 (with cleaning roller 136 or with already released cleaning roller 136), the holding element 144 must be removed from the cassette 132 beforehand.In the embodiment described, the support member 144 is connected to the cartridge 132. It is also possible in principle for the holding element to be connected to the cassette holder 150. The holding element 144 is connected to the cassette 132 in such a way that, when the cassette 132 is movable (by corresponding mounting on the cassette holder 150), this corresponding movement "takes along".In a variant of an exemplary embodiment (FIG. 21 ), the cleaning roller 136 is connected to the holding element 144 (for example by means of a press fit) in such a way that, when the holding element 144 is removed in the removal direction 164, the cleaning roller 136 remains held on the holding element 144 and is carried along.This entrainment with the holding element 144 can be prevented, for example, by an operator exerting a corresponding force from below on the cleaning roller 136 when he releases and decreases the holding element 144 and thus also decreases from the cleaning roller 136.Otherwise, the floor cleaning appliance 120 functions as described above.In FIG. 22, a bottom view of the floor cleaning apparatus 122 is shown.In this embodiment, a sweeping brush 166 is also rotatably disposed on the bottom head 122. Side brushes 168 are also provided.The cassette 132 is provided with a scraper device 164 and a mouth device 66, similar to the cassette 42. With regard to an embodiment of the cassette, reference is made to the non-prepublished German patent application No. 10 2024 103 709.1, dated 9 February 2024.In the case of the floor cleaning device 10 and in the case of the floor cleaning device 120, the corresponding cassette 42 or 132 can be removed from the cassette 42 or 132 in the same removal direction as the cleaning roller 36 when the cassette 42 or 132 is fixed to the corresponding floor head 12 or 122.In a further exemplary embodiment of a floor cleaning appliance, which is shown in FIGS. 24, 25, 26 to 27 and is denoted there by 176, a floor head 178 with a receiving shaft 180 is provided. The receiving tray 180 receives a cassette 182. The receiving shaft 180 is open at an underside 184 towards the installation plane. It is also open laterally via an opening 186. As described above, a corresponding cleaning roller can be removed from the cassette 182 and thus from the bottom head 178 via the opening 186 when the cassette 182 is fixed to the bottom head 178.The cartridge 182 can be removed from the bottom head 178 from the bottom 184 (see FIGS. 25, 26). The receiving shaft 180 has an opening 188 on the underside 184, in which opening the cleaning roller is positioned during a cleaning operation.The cartridge 182 is detachable from the bottom head 178 and can be removed through this opening 188. A removal direction is in this case in particular transverse to the removal direction of the cleaning roller from the cassette 182.A removal direction for removing the cassette 182 from the bottom head 178 has a transverse component to the placement plane 26.In a further exemplary embodiment of a floor cleaning appliance, which is shown in FIGS. 28 and 29 and is denoted by 190, a floor head 192 is provided, which comprises a receiving shaft 194. A cassette 196 is removably positioned in this receiving well 194.The cassette 196 holds a cleaning roller 198 (see Fig. 29).The cleaning roller 198 is positioned on the cartridge 196 via its retainer so that it is removable from the cartridge 196 when seated in the receiving tray 194 via a bottom surface 200 of the bottom head 192.It can be pivoted out of the cassette 196 with the receiving shaft 194 in particular (compare FIG. 28 ).In one embodiment, a fixing device 202 is seated on the end face of the cleaning roller 198. This fixing device 202 prevents the cleaning roller 198 from being released on a corresponding holding element with pivot bearing. By releasing the fixing device 202, the cleaning roller 198 can be pivoted out, as shown in FIG. 28, and can thereby be released from the cassette 196 and can thereby in turn be released from the base head 192.A corresponding pivotability can be supported in that, for example, an inner drive motor 204 can be pivoted to the floor head 192 via a corresponding bearing device 206.In a cleaning operation of the floor cleaning appliance 10, this pivotability is blocked on the bearing device 206.In a variant of the floor cleaning appliance 190, the receiving shaft 194 is open laterally with an opening 208. This opening 208 is openably closed by a cover 210.When the cover 210 is open, the cleaning roller 198 can also be removed from the cassette 196 in a removal direction 212 parallel to the axis of rotation of the cleaning roller 198, as selected by an operator.In the floor cleaning appliance 190, the cleaning roller 198 can be removed with a removal direction transversely to the placement plane 26.In the variant of the exemplary embodiment, it is also possible to remove the cleaning roller 198 from the cassette 196, which is fixed to the base head 192, from the cassette 196 in the removal direction 212 parallel to the placement plane 26.An embodiment of a cleaning station 214 is particularly for cooperation with the floor cleaning appliance 190. The cleaning station 214 comprises a station body 216. The station body 216 comprises a receiving chamber 218 with a receiving chamber 220. A placement plane 222 is provided, which serves for placing the floor cleaning appliance 190.The placement plane 222 forms a ceiling wall of the receiving chamber 218 or is arranged above such a ceiling wall.The placement plane 222 is provided with an opening 224 to the receiving space 220.If the floor cleaning appliance 190 is properly positioned at the cleaning station 214, then the receiving space 220 lies below the floor cleaning appliance 190 with respect to a height direction 226.The station body 216 is provided with at least one ramp 228, via which the floor cleaning appliance 190 can be moved onto the installation plane 222.In a cleaning position 230 of the floor cleaning appliance 190 at the cleaning station 214, the latter is positioned such that the cleaning roller 198 lies at the opening 224.The cleaning station 214 is provided with a transport device 232. The transport device 232 has a receptacle 234, which serves to receive a cleaning roller 198 released from the base head 192.The receptacle 234 is positioned to receive the cleaning roller 198 at, and more particularly in, the opening 224.The transport device 232 is arranged movably and movable in such a way that a cleaning roller 198 accommodated by the receptacle 234 can be brought through the opening 224 into the accommodation chamber 220 of the accommodation chamber 218.In one exemplary embodiment, the transport device 232 is mounted on a pivot bearing 236 such that it can be pivoted about a pivot axis 238.The pivot bearing 236 is positioned, for example, in the region of the receiving chamber 218 and, in particular, below the opening 224 (with respect to the height direction 226).The transport device 232 is controlled in particular by a corresponding control device of the cleaning station 214.In a first position 240 (FIG. 30 ), the transport device 232 is aligned with its receptacle 234 on the floor cleaning machine 190 with the cleaning roller 198. The cleaning roller 198 is detached from the cassette 196 as described above. The described pivoting movement (compare FIG. 28 ) is carried out via the transport device and this results in a final detachment from the bottom head 192 and in particular from the cassette 196.In a second position of the transport device 232 (not shown in the drawings), the detached cleaning roller is then deposited in the receiving space 220.According to the invention, a floor cleaning appliance is provided in which the cleaning roller (for example the cleaning roller 36) can be released from the floor head (for example the floor head 12) in a type of two-step process.The cleaning roller 36 can first be removed from the bottom head 12 and thereby from the associated cassette 42.The "empty" cassette 42 can then be removed from the bottom head 12.It is also possible in principle to remove the cassette 42 with the cleaning roller 36 fixed thereto from the bottom head 12.It is thereby possible, for example, to remove the cleaning roller 36 for its own cleaning roller from the floor head 12 (for example in a washing machine). The cassette 42 remaining on the bottom head 12 can be cleaned at a cleaning station, for example.List of reference characters10 Floor cleaning appliance 12 Floor head 14 Floor head body 16 Wheels 18 Wheel axis 20 Forward travel direction 22 Surface to be cleaned 24 Roller 26 Placement plane 28 Navigation device 30 Underside 32 Upper side 34 Receiving shaft 36 Cleaning roller 38 Lateral side 40 Opening 42 Cassette 43 Cover 44 Holding device 46 Fixing device 48 Cassette holder 50 Drive motor 52 Driver 54 Rotation axis 56 Tank device for dirty fluid 58 Tank device for cleaning liquid 60 Moistening device 62 Feed 64 Scraping device 66 Opening device 68 Holding element 70 Rotary bearing 72 Further holding element 74 Removal direction 76 Removal direction 78 Cover 80 Holding element 82 Rotary bearing 84 Pivot bearing 86 Cover 88 Cleaning guide 90 Placement body 92 Ramp 94 Placement plane 96 Position 98 Arm 100 Bracket 102 Arm (further) 104 Guide device 106 Direction / opposite direction 108 110 engagement region 120 floor cleaning device 122 floor head 124 lid 126 tank device for cleaning liquid 128 tank device for dirty fluid 130 receiving shaft 132 cassette 134 holding device 136 cleaning roller 138 opening 140 drive motor 142 region 144 holding element 146 pivot bearing 148 fixing device 150 cassette holder 152 transverse wall 154 end face 156 region 158 holding element fixing device 160 latching hook 162 operating element 164 removal direction 166 sweeping brush 168 side plane 176 floor cleaning device 178 floor head 180 receiving region 182 cassette 184 underside 186 opening 188 opening 190 floor cleaning device 192 floor head 194 receiving shaft 196 cassette 198 cleaning roller 200 underside 202 fixing device 204 drive motor 206 bearing device 208 opening 210 lid 212 removal direction 214 cleaning station 216 station body 218 receiving chamber 220 receiving space 222 installation plane 224 opening 226 height direction 228 ramp 230 cleaning position 232 transport device 234 receptacle 236 pivot bearing 238 pivot axis 240 first positionReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
