Description

CLEANING SYSTEM AND METHOD OF OPERATING A CLEANING SYSTEM

The present invention relates to a cleaning system, comprising a cleaning trolley, and a method for operating a cleaning system with a cleaning trolley.

Despite modern cleaning machines, especially in the area of interior cleaning, some of which can be automated, cleaning trolleys are of great importance in the area of daily cleaning. Particularly noteworthy are special cleaning tasks to be carried out manually in larger buildings, for example office buildings, hotels, care facilities, hospitals, airports, event buildings or the like. The cleaning trolleys are used to carry cleaning utensils. Examples of this are in particular special manually operated cleaning tools, containers for storing cleaning accessories, cleaning fluids or cleaning chemicals, containers for holding dirty liquid or waste, cleaning cloths or other objects for surface cleaning. On the cleaning car recordings are usually provided for receiving and / or carrying such cleaning utensils.

The cleaning trolleys include rollers so that they can usually be moved manually over a floor surface by a user. For improved handling, for example, a handle device for the loading user is provided. The rollers of the cleaning trolleys can be fixed, that is, unguided. Alternatively it can be provided that the rollers are steering rollers. A mixture of unguided castors and swivel castors can also be provided. The cleaning trolleys usually comprise a frame on which the Rol len are arranged. In the present case, for example, an open frame, for example for the arrangement of containers, can be regarded as a frame. In the present case, a closed frame in the sense of a body, which for example comprises side walls and / or doors for closing a receiving space for cleaning utensils, can also be viewed as a frame.

In the case of cleaning tasks using cleaning trolleys, it is desirable to carry out cleaning tasks efficiently and in accordance with requirements, in which, for example, a plurality of rooms to be cleaned is provided. It may be necessary to clean the rooms in the specified order. It may be necessary to carry out different cleaning tasks in the different rooms, whereby different cleaning utensils can be used. For this reason, there is, for example, the need to equip the cleaning trolley as required when taking up work, preferably all of the necessary cleaning utensils being available and superfluous cleaning utensils not being carried along.

In the present case, any area to be cleaned can be viewed as a “room”. The space can have physical boundaries such as walls. Alternatively or in addition, virtual boundaries can be provided in the sense of a predeterminable definition, where the space ends without the presence of physical boundaries. The room can be indoors or outdoors. Accordingly, a room can be, for example, a room, a corridor, a hall, a foyer, a path, a square or some other type of open space.

DE 10 2018 111 423 B4 describes a cleaning system with a cleaning trolley and a data processing device. The cleaning trolley includes a frame that has a unique machine-readable identifier is provided. The cleaning trolley can thereby be identified in the data processing device. In the data processing device, compilations of cleaning utensils tailored to cleaning tasks are stored. As an alternative or in addition, the condition of the cleaning trolley is stored in the data processing device.

WO 2019/092062 A1 describes a cleaning trolley which has a support body and a communication device holder for receiving a mobile communication device, the communication device holder being fixed on the support body.

The object of the present invention is to provide a cleaning system and a method for operating a cleaning system that enables cleaning tasks to be carried out in a user-friendly and reliable manner.

This object is achieved by a cleaning system according to the invention, comprising a cleaning trolley and an external additional device, the cleaning trolley comprising a frame with rollers for moving on a floor area, at least one receptacle for receiving and / or carrying cleaning utensils and an interaction device with a hand-held operable interaction element, wherein the additional device is designed to be portable and a user application program for processing cleaning-related information is stored executable on the additional device and / or can be operated via the additional device, wherein the interaction device and the additional device can be coupled to one another via a communication connection, and input information for operation of the user application program as a function of an actuation of the interaction element by the user from the interaction device to the additional device via indirectly and can be processed by the latter.

In the cleaning system according to the invention, an external additional device is used in addition to the cleaning trolley. Can be provided in particular that the cleaning system comprises more than one cleaning trolley and / or more than one external additional device. The cleaning trolleys and / or the additional devices can be configured identically or differently. It can be provided that a respective additional device can optionally be used with one of the cleaning trolleys or vice versa.

A user application program can be operated via the additional device, which can for example be stored on the additional device itself - in particular as a so-called "app" - and / or stored spatially remotely from the additional device and can be executed there - for example on a server or in a " Cloud ". The user application program allows the processing of cleaning-related information, for example for processing a cleaning plan, in the context of which cleaning tasks are carried out using the cleaning trolley.

The cleaning trolley comprises an interaction device which can be coupled to the additional device via an at least unidirectional communication link. To facilitate handling of the additional device and to operate the user application program, the interaction device comprises the interaction element. The interaction element can be operated manually, whereby it can preferably also be operated by the user with gloves, which, for example, make it difficult or even impossible to use a touch-sensitive display unit of the additional device. Inputs from the user via the interaction element can be transferred to the additional device and processed by the latter to operate the user application program. For example, the inputs of the user can be used as cleaning-related information when processing a cleaning plan. It is conceivable, for example, that the user acknowledges instructions from the user application program or confirms the planned or completed cleaning of rooms. Possible entries are discussed below. The interaction device with the interaction element forms a user-friendly interface for interacting with the user application program via the additional device. An operation of the additional device itself, ie physically on the additional device, can thereby preferably be dispensed with. A more hygienic operation of the additional device is made possible by the fact that the user can use the interaction element. Nevertheless, it is preferably provided that the user can alternatively or additionally physically operate the additional device.

The interaction element preferably makes it possible to increase the acceptance for the use of additional devices in connection with cleaning trolleys and a user application program for performing cleaning tasks. For example, when using the additional device without an interaction element, cleaning service providers, customers and third parties could get the impression that the user is not working, but is wasting time operating the additional device. This impression can be prevented by using the interaction element on the cleaning trolley.

The communication link between the interaction device and the additional device can be wireless and / or wired.

For example, the communication link is a radio link. In particular, a Bluetooth connection or a WiFi connection can be provided.

For example, an NFC connection between the Interaktionsein direction and the additional device, which requires a spatial proximity of these two components, is conceivable. This proximity can definitely be advantageous and / or desirable, for example to ensure a secure communication link and / or to ensure that a display unit of the additional device can be used and is located in the user's field of vision. The interaction device and the interaction element are advantageously designed in such a way that they are functional independently of the system with additional devices of different design and software stored on them (platform-independent and / or software-independent).

The interaction device can for example comprise a microprocessor for processing the inputs of the user on the interaction element. It is conceivable that a computer program can run on the microprocessor, in particular via embedded software. The software can be updateable. Updates for the software can, for example, be transferable from the additional device to the interaction device.

The at least one receptacle for cleaning utensils can be designed differently. For example, at least one container is provided, at least one holding part for hanging and / or for clamping and / or ratcheting holding of the cleaning utensil, a support part on which cleaning utensils can be placed, etc.

The additional device preferably comprises an output unit. For example, cleaning-related information from the user application program can be output to the user via the output unit.

For example, an optical output unit in the form of a display unit can be provided as the output unit, in particular with a controllable image display.

As an alternative or in addition, an acoustic and / or a haptic output unit, for example, can be provided as the output unit.

The additional device can be, for example, a smartphone or a tablet computer. In addition to the option of operating the additional device via the interaction element, conventional operation of the accessory can preferably be used. set device be possible. In particular, as already mentioned, a physical interaction, for example via a touch-sensitive display unit (touchscreen), is conceivable here. As an alternative or in addition, for example, voice control and / or gesture control using a camera of the additional device is provided.

It can be favorable if output information of the user application program can be transmitted from the additional device to the interaction device and if the interaction device comprises an information unit for outputting information to the user as a function of the output information. In this way, there can in particular be a bidirectional communication connection between the additional device and the interaction device. Depending on the user application program, the user can be provided with information on the information unit, for example for working through a cleaning schedule.

The information unit can be, for example, a visual information unit. The optical information unit can be designed differently. For example, a controllable image display is provided. As an alternative or in addition, the information unit can be or comprise a lighting device which provides information, for example in a luminous manner, by means of different colors. Leuchtele elements, for example LED diodes, can be provided.

In the case of an optical information unit, a single-segment display or a multi-segment display is provided, for example.

As an alternative or in addition, the information unit can be designed acoustically and / or haptically, for example. This makes it possible to provide information acoustically via a loudspeaker and / or haptically, for example by vibration. The brightness of the optical information unit, the volume of the acoustic information unit and / or the intensity of the haptic information unit can be adjustable.

It is favorable if the interaction element comprises or forms the information unit. A separate information unit can be saved in this way. This enables a structurally simple and compact design of the interaction device. Information that is output on the interaction element can preferably be easily perceived by the user. If the interaction element is in the user's field of vision when it is operated, the user can perceive any information immediately in this way. The arrangement of the information unit on the interaction element therefore increases the likelihood that information will be perceived by the user.

The output information and, depending on this, the notes on the note unit can be designed differently. For example, the output information can include:

Display of images;

Representation of texts;

Playing videos, for example to illustrate cleaning work to be carried out;

Color-coded information, for example based on the luminous color; Feedback information. If the user operates the interaction element, for example, the receipt of relevant input information can be acknowledged in return via output information. For example, output information that is conveyed by means of text, color, image, noise and / or vibration is conceivable.

Feedback information depending on incorrect input information or input information that cannot be processed. For example, incorrect entries are conveyed through text, color, image, noise and / or vibration. Spontaneous notices sent to the user by the user application program ("push messages").

It has proven to be advantageous, for example, if the interaction element is a rotary knob or comprises a rotary knob. In this way, the interaction element can be operated particularly easily. For example, a diameter of approximately 5 cm to 10 cm can prove to be advantageous for easier handling of the rotary knob.

In a preferred embodiment, an axis about which the rotary knob can be rotated can, for example, have an angle of 45 ° or less relative to a vertical. As "vertical" an axis perpendicular to a contact plane defined by the rollers with the floor surface is angese hen, the contact plane being viewed as horizontally oriented and the intended use of the cleaning trolley on the floor surface is assumed.

The angle can preferably be less than 30 ° with respect to the vertical.

The rotary knob can preferably have a corrugation with ridges and / or knobs on an outer circumference in order to facilitate handling by the user, for example with gloves.

The interaction device can, for example, evaluate a position of the rotary knob and / or a speed of rotation of the rotary knob to determine the input information.

It can be advantageous if the interaction element is a push button or toggle button or comprises one. By pressing or by tilting the interaction element, the interaction device can, for example, evaluate input information. For example, a restoring element can be provided, by means of which the interaction element returns to a starting position in the sense of a basic position after pressure or after tilting.

Haptic feedback from the interaction element when the user inputs it can be advantageous.

It can prove to be particularly advantageous in practice, for example, if the interaction element is or comprises a combined turn-tilt button and / or turn-push button. It has been shown in practice that a particularly easy-to-use multifunctional interaction element can be provided in this way.

The interaction device and in particular the interaction element is preferably waterproof, but at least splashproof, and / or dustproof. A possible malfunction of the interaction device due to undesired penetration of water and / or dust is thus prevented. For example, at least one norm of the IP protection class standard is fulfilled. Provision is made, for example, for the interaction device to be at least IP54-compliant, preferably at least IP65-compliant.

The cleaning trolley advantageously comprises a handle device with at least one handle element for guiding the cleaning trolley by a user. The cleaning trolley can be moved across the floor in a user-friendly manner using the handle device.

The handle device comprises, for example, two handle elements arranged at a distance from one another. Provision can be made for the grip elements to be aligned essentially horizontally and to be gripped vertically by the user with the fingers. For example, a handle device with two handle elements which are oriented essentially vertically and can be grasped horizontally by the user with the fingers can prove to be ergonomic. The at least one grip element can be height-adjustable and thereby preferably adapted to the body size of the user.

It is favorable if the interaction element is arranged on the handle device or is encompassed by it. This allows the user to easily access the interaction element. This increases the user friendliness. For example, the interaction element is positioned between two handle elements of the handle device which are arranged at a distance from one another, in particular essentially in the center of the handle device.

Provision can be made for the interaction device as a whole to be arranged on the handle device or to be encompassed by it.

The handle device can preferably be releasably fixed on the frame of the cleaning trolley. This advantageously offers the possibility of fixing the handle device on the cleaning trolley in a different position, depending on the user's wishes. As an alternative or in addition, the handle device can, for example, be attached to a different type of cleaning trolley.

In the case of a handle device that can be detached from the cleaning trolley, it is advantageous if the interaction element is arranged on the handle device as explained above. For example, the advantages of the invention can be achieved with several cleaning trolleys on which the handle device can optionally be fixed without having to keep several interaction devices available for this purpose.

For connection to the cleaning trolley, the handle device and the frame comprise, for example, corresponding connecting elements. The connecting elements can, for example, enable a clamping and / or locking connection. A blocking device can be provided, with which a loosening of the handle device from the cleaning trolley can be prevented. Connecting and / or releasing the handle device can preferably be carried out manually and / or without tools.

It can be provided that the additional device, even if there is an existing communication connection with the interaction device, is arranged spatially remote from the cleaning trolley. In this case, a wireless communication link is particularly advantageous. For example, the user carries the additional device on his body, for example in a bag.

It can prove to be advantageous if the cleaning trolley comprises a receiving unit with a receiving device for receiving the additional device.

The additional device can be positioned on or in the receptacle. It preferably takes a defined position on the cleaning trolley. This can prove to be particularly advantageous for the reliability of the communication connection. Positioning in the receptacle can ensure, for example, that a display unit of the additional device is in the user's field of vision. For example, instructions from the user application program are shown on the display unit and can thus be more easily recognized by the user when the additional device is positioned in the receptacle.

It can prove to be advantageous, for example, if a surface normal of the display unit has an angle to the horizontal of approximately 20 ° to 70 °, the horizontal in this case being viewed as being oriented parallel to the contact plane of the Rol len.

It can be advantageous if it can be determined whether an additional device is positioned in the receptacle. For example, the arrangement of the additional device is recorded inductively. In the case of an additional device arranged in the receptacle, for example, information can be output via the information unit of the cleaning vehicle instead of via the information unit of the additional device. It is favorable if the receptacle is arranged on the handle device or is encompassed by it. As a result, there is advantageously the possibility that the additional device with display unit can be seen and / or operated particularly easily by the user.

If the handle device is detachable, the receptacle together with the additional device on another cleaning trolley and / or on the cleaning trolley can be fixed at different positions in this way. The advantages that can be achieved by providing the receptacle can thereby preferably be achieved on more than just one cleaning trolley.

The receptacle is preferably positioned between two grip elements arranged at a distance from one another, in particular essentially in the center of the grip device. If the interaction element is arranged on the handle device, the receptacle is preferably arranged in the access direction behind the interaction element so that the interaction element can be accessed and it is not covered by the additional device.

It can be provided that the receiving unit is arranged as a whole on the Griffein direction.

The receptacle is advantageously variable in size. Accordingly, the receiving unit can comprise or form an adapter unit which can be adapted to additional devices of different sizes and which allows different additional devices to be taken up.

It can be provided, for example, that the receptacle is arranged between two holding elements that are movable relative to one another and that the respective additional device can in particular be held between the holding elements in a form-fitting manner. A holding element is net angeord, for example, on a support part which is designed to be displaceable in order to change the size of the receptacle. The support part is displaceable on the handle device, for example stored. The position of the support part relative to the handle device can, for example, be fixable so that the size of the receptacle is maintained and the additional device is thereby held particularly reliably.

The receiving unit can comprise a support part on which the additional device can be placed. For example, the additional device can be leaned flat against the support part with a rear facing away from a display unit. The support part is in particular the above-mentioned support part which is displaceable relative to the handle device.

The receiving unit preferably comprises a blocking element for securing the additional device against being removed from the receptacle. This ensures that the additional device cannot be unintentionally removed from the receptacle. In particular, improper removal can be prevented, for example, in that the blocking element is secured by a lock cylinder or a similar safety device and the receptacle can only be released when the correct key is used to remove the accessory.

It can be provided that the additional device is secured directly or indirectly via the blocking element. In the latter, the receptacle is blocked against widening, for example by the blocking element, so that the additional device cannot be removed.

In a preferred embodiment, for example, a blocking element can be provided which is in engagement with a support part of the receiving unit and thereby prevents displacement of the support part, in particular relative to the handle device.

It is advantageous if a charging unit for charging the additional device is arranged on the receiving unit or if the receiving unit comprises a charging unit. As a result, an energy storage device of the additional device can be charged while it is being positioned in the receptacle. the The service life of the additional device, in particular with regard to the implementation of cleaning tasks according to a cleaning plan, is extended as a result.

It is conceivable, for example, that the additional device can be loaded contactlessly by induction. For example, an inductive charging unit is available for this purpose on the aforementioned support part on which the additional device is based.

As an alternative or in addition, it can be provided that the additional device is charged in a cable-bound manner. For example, an electrical connection element is provided for connecting a charging cable for the additional device. The connection element is, for example, a USB socket.

The cleaning trolley preferably comprises an electrical energy storage device for providing electrical energy for the Interaktionseinrich device and / or for the additional device. The energy storage device is, for example, a rechargeable battery, which is preferably removable. A receptacle is preferably provided for the energy storage device, which is advantageously arranged on the handle device. The energy storage device preferably acts on the charging unit via which the additional device can be charged.

As mentioned at the outset, the user application program can, for example, be stored in an executable manner on the additional device and is installed there as an "app", for example.

As an alternative or in addition, a preferred embodiment of the invention provides that the cleaning system comprises a data processing device which is arranged spatially remote from the cleaning trolley and from the additional device and which is or can be communicated with the additional device, and cleaning-related information of the loading User application program from the additional device to the data processing device and / or vice versa are transferable. The data processing device can be configured as a server and / or as a plurality of computers connected to one another, for example as a “cloud”. The user application program can for example be executed on the data processing device. Cleaning-related information can be exchanged between the additional device and the data processing device. In this sense, for example, input information from the additional device can be processed and transmitted to the data processing device for processing by the user application program. Conversely, information from the user application program can be transmitted from the data processing to the additional device. Outputs can be provided, for example, via an information unit on the additional device and / or an information unit on the cleaning trolley.

Provision can be made for a cleaning plan in particular to be provided via the data processing device and to be transmitted to the user application program on the additional device. This gives, for example, the possibility of creating and managing cleaning plans centrally for a plurality of cleaning trolleys and users, with the cleaning tasks being processed decentrally.

A report on the processing of the cleaning plan can, for example, be transmitted from the user application program on the additional device to the data processing device and evaluated or collected there.

A cleaning plan can advantageously be stored in the user application program. The cleaning schedule can include cleaning-related information. The cleaning schedule is used in particular to inform the user about cleaning tasks, preferably with a view to thorough, systematic and time-saving cleaning. It is desirable here to carry out cleaning tasks flexibly, depending for example on the occupancy or the accessibility of a room and / or dependent cleaning tasks that have to be carried out at short notice can be rearranged, supplemented, deleted or otherwise influenced in the order of the cleaning schedule.

The cleaning plan includes, for example, information about rooms to be cleaned.

The cleaning plan includes, for example, room-related information about objects to be cleaned in at least one room. Provision can be made for information about objects in at least one room to be available that are not to be cleaned.

The cleaning plan includes, for example, space-related information about the type of cleaning of at least one object to be cleaned in a room.

The cleaning plan includes, for example, information relating to the equipment of the cleaning trolley for processing the cleaning plan. For example, the cleaning trolley can be equipped with the necessary cleaning utensils when it starts operating. In particular, it can be stored in the cleaning plan which cleaning utensils are intended for which cleaning task or as a whole, in particular for which room and / or for which object within a room.

The cleaning schedule is preferably linked to a clearly identifiable cleaning trolley.

The cleaning plan can preferably be processed using a workflow and / or in dialog operation with the user. For example, the user is informed about cleaning tasks to be carried out via the additional device and / or an information unit on the cleaning trolley. The user can interact via the interaction element, for example Call up cleaning tasks;

Acknowledge cleaning tasks; confirm completion of cleaning tasks;

Call up information about the condition of the cleaning trolley; Call up more information on how to perform a cleaning task.

Accordingly, it is advantageous if, when the cleaning plan is being processed, instructions for the user can be provided on the additional device and / or on an information unit of the interaction device.

When the cleaning plan is being processed, inputs from the user via the interaction element can advantageously be processed in order to carry out the cleaning plan.

The cleaning schedule can advantageously be changed, especially after processing has started. This enables, for example, versatile, demand-dependent cleaning processes in the sense of "demand-based cleaning". As already mentioned, the user can, for example, be informed of a change in the pending cleaning tasks depending on the occupancy or the accessibility of a room. Inaccessible rooms and associated cleaning tasks can be skipped. Cleaning tasks can be added for accessible rooms. Necessary cleaning tasks to be inserted can thus be integrated into the cleaning schedule. The user can be informed about this, for example, by means of a message (for example a push message).

The cleaning system, in particular the cleaning trolley, can comprise at least one sensor device. Information and / or states can advantageously be recorded via the at least one sensor device, with a view to reliably carrying out cleaning operations, for example with regard to processing the cleaning plan. For example, the cleaning system, in particular the cleaning trolley, comprises a sensor device with which a space in which the cleaning trolley is positioned can be identified. The determination of the room enables, for example, the user application program to inform the user about a cleaning task to be performed in this room. Information relating to this can be output, for example, via the additional device and / or an information unit of the cleaning trolley. As an alternative or in addition to checking the processing of cleaning tasks, entering the room can be logged.

For reasons of data protection law, it can be advantageous if, instead of the position of the additional device, the position of the cleaning trolley can be determined, for example by identifying the room.

The room can be identified, for example, via landmarks ("beacons") arranged on or in the room, which can be detected, for example, via Bluetooth. As an alternative or in addition, for example, identification can take place via RFID elements that are assigned to the room and are arranged on or in the room.

The at least one sensor device of the cleaning trolley can advantageously comprise an RFID reading device or form such a device for detecting RFID elements.

Depending on the identified room, instructions for cleaning the room can advantageously be provided, depending on a cleaning plan stored in the user application program.

Provision can be made for a map of the rooms to be cleaned with the cleaning car to be stored in the user application program, in particular linked to a cleaning plan. When the room is identified, it is possible to determine the position of the cleaning trolley within the map. Cleaning tasks that are assigned to the rooms are advantageously stored in the cleaning plan in such a way that the number and / or the distance of empty trips during which no cleaning is carried out is kept as low as possible. By identifying rooms, it is advantageously possible to record the sequence in which the rooms are cleaned. For an evaluation of the cleaning carried out, the efficiency in the processing of the cleaning plan can be determined and in particular it can be determined whether the rooms have been visited with the lowest possible number and / or distance of empty trips in which cleaning is not carried out.

It is advantageous if the user can be instructed to carry out cleaning tasks in order to ensure the best possible cleaning result, to avoid incorrect cleaning and / or to enable cleaning utensils to be used in a way that conserves resources. For this purpose, it can be advantageous if the user is instructed which cleaning utensil is to be used. This can be done, for example, via the additional device or an information unit on the cleaning trolley. In a preferred embodiment, the information elements mentioned below are provided.

It can be advantageous if information elements are arranged on containers of the cleaning trolley and / or on receptacles for cleaning utensils, which can be activated depending on the identified space. The activation can preferably take place as a function of a cleaning plan stored in the user application program for the room. The information elements can be designed optically or acoustically, for example. Luminous elements, for example, are used as visual indicators. The lighting elements can be activated for the cleaning utensil to be used. In this way, the user can be instructed to remove the correct cleaning utensils via a so-called "pick by light" system. Acknowledgment that a specified cleaning utensil has been removed can be made, for example, via the interaction element.

The cleaning system, in particular the cleaning trolley, can preferably include a sensor device with which the user's additional device and / or an authorization holder of the user can be detected. For example, this has the purpose of verifying the user as authorized in order to prevent misuse and / or theft. It can be provided that the user must be authorized to drive the cleaning trolley. With positive identification, i. H. the user is authorized to drive the cleaning trolley, for example a brake on the cleaning trolley can be unlocked. In the event of a negative detection, if the user is not authorized, the brake remains blocked and the cleaning trolley cannot be moved. Alternatively or in addition, it can be provided, for example, that access to certain receptacles for cleaning utensils and / or the release of cleaning utensils in certain receptacles is only possible if the user is authorized, whereas unauthorized users are not able to access the cleaning utensils remove.

The identification of the additional device can advantageously take place via the communication link between the identification device and the additional device.

The authorization holder can be identified, for example, by an RFID reader on the cleaning trolley, the authorization holder being an RFID element.

Provision can be made for the detection of the additional device and / or the authorization holder to take place automatically, without any action on the part of the user.

The cleaning system, in particular the cleaning trolley, preferably comprises a sensor device with which cleaning utensils can be detected, that are carried on the cleaning trolley. When equipping the cleaning trolley, cleaning utensils can, for example, be recorded individually or collectively by the sensor device and identified as cleaning utensils that are to be carried or that are not to be carried by outputting a positive or negative acknowledgment. This makes it easier to equip the cleaning trolley.

Alternatively or in addition, during the cleaning to be carried out, in particular depending on a cleaning plan, for example the cleaning utensil can be checked for correctness by means of the sensor device and the user can be given a corresponding feedback.

The detection of the cleaning utensils can for example be based on RFID, with an RFID reader being arranged on the cleaning trolley and the cleaning utensils comprising RFID elements.

The cleaning system, in particular the cleaning trolley, preferably comprises a sensor device with which the inventory of consumables that are carried with the cleaning trolley can be detected. For example, the fill levels of containers and / or the number of existing or used cleaning cloths are recorded. Depending on the inventory, the user can be informed that consumables should be replenished. In the event of excessive consumption, the user can be asked to use cleaning utensils more sparingly. The monitoring of the consumption of cleaning utensils can be used as an alternative or in addition to documentation purposes, for example if cleaning cloths have to be changed after certain areas of coverage, times or in certain rooms.

As mentioned at the outset, the present invention also relates to a method.

A method according to the invention for operating a cleaning system is proposed according to the independent method claim, wherein the The cleaning system comprises a cleaning trolley which can be moved over rollers on a floor surface and is designed to pick up and / or carry cleaning utensils, the cleaning trolley comprising an interaction device with a hand-operated interaction element, and wherein the method comprises the following:

FIG. 1 shows a perspective illustration of a partial view of a cleaning system according to the invention, generally assigned the reference numeral 10.

The cleaning system 10 comprises, in particular, a cleaning trolley 12 and a portable electronic accessory device 14.

More than one cleaning trolley and more than one additional device 14 can be part of the cleaning system 10. FIGS. 14 and 15 show further cleaning trolleys 100 and 200, and FIGS. 3 and 8 show a further additional device 300 instead of the additional device 14.

Overall, the cleaning system 10 according to the invention can comprise several cleaning trolleys and several additional devices, with at least one cleaning trolley and one additional device being provided. The invention is initially explained using the example of the cleaning trolley 12 and the additional devices 14, 300. In the present case, a component of the cleaning system 10 is a data processing device 16 which is arranged spatially remote from the cleaning trolley 12 and from the additional device 14. However, this is only an optional component of the cleaning system 10 according to the invention.

The cleaning trolley 12 comprises a frame 18 with a lower frame part 20 and a frame upper part 22 spaced apart from this in a vertical direction. The frame lower part 20 and the frame upper part 22 are connected to one another via support elements 24 in the form of profiles.

On the lower frame part 20, rollers 26 for moving the cleaning trolley 12 are held on a floor surface 28. The rollers 26 are swivel castors in the present case. Alternatively or partially unguided rollers can be provided.

In the present case, the rollers 26 define a contact plane which coincides with a plane 28 defined by the floor surface 28 when the cleaning trolley 12 is used properly. It is assumed, non-limiting, that the bottom surface 28 is oriented horizontally.

In the present case, position and orientation information is to be understood as referring to the intended use of the cleaning trolley 12 on the horizontally oriented floor surface 28.

To move the cleaning trolley 12, a handle device 30 is provided to grab it by the user, not shown in the drawing.

The cleaning trolley 12 is used to carry cleaning utensils, in particular for manual cleaning. For this purpose, the cleaning carriage comprises 12 receptacles 31 for cleaning utensils.

The receptacles 31 include, for example, containers 32 which are held on the frame 18 and are designed, for example, in the shape of a bucket. The containers 32 serve, for example, to hold cleaning fluids or cleaning cloths and manual cleaning tools (these are not shown) and can in turn be viewed as cleaning utensils. As a further cleaning utensil, a container 34 for receiving waste is held on the frame 18 by way of example.

For example, on the upper frame part 22, receptacles 31 in the form of holding parts 36 can be set on the frame 18, which are hidden in FIG. 1 and shown in FIG. Manual cleaning tools such as mops, flat mops or brooms, for example, can be held in a force-fit manner on the holding parts 36 and removed if necessary.

In the case of the cleaning trolley 14, the frame 18 is designed to be open and has no doors or side walls in order to close the receiving space 38 formed between the frame lower part 20 and the frame upper part 22.

In contrast, the cleaning trolleys 100 include doors 40 and side walls 42, so that the receiving space 38 is at least partially closed. It is understood that behind the doors 40 and the side walls 42 on 31 can be provided for cleaning utensils.

A ceiling wall 46 can be provided on the frame 18 at the top.

As can be seen in particular from FIGS. 3 and 4, the handle device 30 comprises a base element 48 and two handle elements 50. The handle elements 50 are fixed on the base element 48 and spaced from one another.

In particular, provision can be made for the grip elements 50 to be held on the base element 48 in a height-adjustable manner. For this purpose, the handle elements 50 can be pivoted about a horizontally aligned axis 52 relative to the base element 48, for example. A securing device 54 can be provided in order to secure the grip elements 50 in a respective position. The handle device 30 is ergonomically designed via the handle elements 50 and also allows longer, fatigue-free guidance of the cleaning trolley 12. For this purpose, the handle elements 50 are vertically aligned in sections so that the user can grip them horizontally with his fingers. This hand position reduces the stress on wrists and / or forearms.

The handle device 30 can in particular be releasably attached to the cleaning trolley 12. For this purpose, the handle device 30 and the cleaning trolley 12 comprise corresponding connecting elements 56, 58.

The connecting elements 56 are arranged on the side of the base element 48 facing the cleaning trolley 12 (FIG. 4). In the present example, the connecting elements 56 comprise clamping elements 60 and locking elements 62.

The connecting elements 58 are arranged on the upper frame part 22 (FIG. 7) and configured to correspond to the connecting elements 56. In the present example, the connecting elements 58 comprise clamping receptacles 64 for the clamping elements 60 and latching receptacles 66 for the latching elements 62.

To assemble the handle device 30, the connecting elements 56, 58 can be brought into engagement with one another and the handle device 30 can thereby be releasably fixed on the cleaning trolley 12.

The handle device 30 comprises blocking elements 68 which are designed to secure the latching elements 62 from the latching receptacles 66 before they are unlatched. The blocking elements 68 can, however, be brought into a release position in order to enable the grip device 30 to be unlatched and thus released from the cleaning trolley 12. In particular, it can be provided that the handle device 30 can be optionally fixed at a plurality of positions on the cleaning trolley 12. For this purpose, the cleaning trolley 12 can have connecting elements 58 at a plurality of positions, in particular on the upper frame part 22.

In a corresponding manner, the handle device 30 can preferably be detachably attached to further cleaning trolleys of the cleaning system 10. FIGS. 14 and 15 show this by way of example for the cleaning trolleys 100 and 200. A plurality of connecting elements 58 can preferably also be arranged on the further cleaning trolleys 100, 200 in such a way that the handle device 30 is fixed in a plurality of positions on the cleaning trolleys 100, 200 can.

By providing only one handle device 30 with a receiving unit for the accessories 14, 300, the construction of the cleaning system 10 is simplified.

In particular, the cleaning trolley 12 together with the handle device 30 can represent an independent invention within the scope of the present disclosure. The same applies to cleaning trolleys 100 and 200.

In the present example, the additional device 14 is designed as a tablet computer 70. The tablet computer 70 comprises output units for outputting instructions to the user, especially instructions from a user application program for cleaning tasks. In particular, an optical output unit is provided, designed as a display unit 72 with a controllable image display. In addition, acoustic and haptic output units are provided.

The tablet computer 70 further comprises a communication device 74 via which communication connections can be set up and used. In particular, there is the option of a Bluetooth connection and the possibility of a communication connection via a telecommunication network or the Internet, in particular with the data processing device 16 (FIG. 8).

The additional device 300 is designed as a smartphone 76 in the present example. The smartphone 76 has dimensions that differ from the tablet computer 70, but it is also equipped with the corresponding output units, in particular the display unit 72, and the communication device 74.

To accommodate the additional devices 14 or 300, the cleaning trolley 12 includes a receiving unit 78 with a receptacle 80. In the present case, the handle device 30 includes the receiving unit 78. This proves to be advantageous because when the handle device 30 is repositioned, an additional device arranged in the receptacle 80 is also new is positioned, for example on one of the further cleaning trolleys 100 or 200. Separate receiving units are not required.

In addition, the arrangement of the receptacle 80 on the handle device 30 is advantageous so that the display unit 72 can be seen by the user and the content of the image display can be perceived in a simple manner. The physical interaction with the additional device 14 or 300 is made easier for the user by arranging the receptacle 80 on the handle device 30. For physical interaction, the display unit 72 is designed, in particular, to be touch-sensitive as a touchscreen.

In addition, there is the possibility of voice control and / or gesture control of the additional device 14 or 300.

The receiving unit 78 is arranged on the base element 48. The base element 48 forms a holding element 82 on the top, on which the additional device 14 can be placed, in particular with a side surface (the following details Guidelines apply accordingly to the additional device 300, which is shown in Figure 3 as an example). The holding element 82 is, for example, groove-shaped in order to ensure a defined position of the additional device 14.

In addition, the receiving unit 78 has a further holding element 84 which is positioned at a distance from the holding element 82 and is arranged above the same. The holding element 84 is fixed to a support part 86 of the receiving unit 78 and is arranged, for example, at the end thereof. The support member 86 engages with the base member 48.

The additional device 14 can be leaned against the support part 86 with the rear facing away from the display unit 72. In particular, the additional device 14 can lie flat on the support part 86. Between the holding elements 82, 84 and the support part 86, the receptacle 80 is formed, in which the additional device 14 is preferably positioned in a form-fitting manner.

The holding element 84 can also be designed in the form of a groove for the form-fitting reception of a side surface of the additional device 14.

When the additional device 14 rests on the support part 86, a surface normal of the display unit 72 is inclined upward relative to the horizontal. The angle of inclination is preferably more than about 20 °. As a result, the display unit 72 assigns it to the user and can be better recognized.

The support part 86 is designed to be movable and, in particular, displaceable relative to the base element 48. In particular, there is the possibility of moving the support part 86 relative to the base element 48 in a height direction, indicated by a double arrow 88, relative to the base element 48. This he allows the distance between the holding element 84 from the holding element 82 to change. The receptacle 80 is variable in size in this way.

The possibility of changing the size of the receptacle 80 increases the versatility of the receptacle unit 78. In particular, there is the possibility given to position additional devices of different sizes in the receptacle 80, in particular the tablet computer 70 on the one hand or the smartphone 76 on the other hand. There is also the option of holding tablet computers of different dimensions and / or smartphones of different dimensions in the receptacle 80.

In the present example, the support element 86 extends through through openings in an upper wall 90 and in a lower wall 92 of the basic element 48 (FIGS. 4 and 6). This is in particular a guide for the support part 86, which makes it easier for the user to handle the receiving unit 78.

The support part 86 can be fixed in a respective position relative to the base element 48. A blocking element 94 is provided for this purpose. The support part 86 and the blocking element 94 can be brought into engagement in a plurality of positions of the support part 86. For this purpose, a toothing 96 is preferably provided on the support part 86, which can be brought into engagement with a corresponding toothing 98 of the blocking element 94 (FIG. 6).

In the present example, the blocking element 94 is designed as a slide 102, which is preferably slidable in a corresponding guide 104 on the basic element 48. A double arrow 106 in FIG. 6 indicates the direction of displacement.

In a retracted release position of the slide 102, the toothings 96, 98 are disengaged so that the support part 86 can be moved. In particular, this offers the possibility of expanding the receptacle 80 in order to remove the additional device 14. Conversely, the receptacle 80 can be reduced in size for fixing the additional device 14.

The slide 102 can assume an advanced engagement position in which the toothings 96, 98 are in engagement with one another. This ensures that Support part 86 against displacement, so that the size of the receptacle 80 is fixed.

Via the blocking element 94 in the engagement position with the support part 86, the additional device 14 can thereby be secured in the receptacle 80 when it is positively received between the holding elements 82, 84.

A securing device 108 is provided for fixing the blocking element 94 at least in the engagement position. The securing device 108 comprises, for example, a lock cylinder 110 with an eccentric arranged thereon, which engages in an opening of the blocking element 94 (FIG. 6). The lock cylinder 110 can only be turned with the mechanical key provided for this purpose.

If the blocking element 94 and the support part 86 are in engagement, an additional device 14 received in the receptacle 80 is protected from theft in this way. The additional device 14 can be released by means of the mechanical key, a set for opening the lock cylinder 110.

A charging unit 112, via which the additional device 14 can be charged, is provided on the receiving unit 78. The charging unit 112 comprises, for example, an inductive charging element 114, which is preferably integrated into the support part 86. When the additional device 14 is arranged in the receptacle 80, electrical energy can be transmitted from the charging element 114 to the energy storage device 14 of the additional device 14.

The charging unit 112 further comprises an electrical connection element 116, in the present case designed as a USB socket. A charging cable, which is connected to the auxiliary device 14, can be connected to the connection element 116. In order to provide electrical energy, the cleaning trolley 12 comprises an energy storage device 118. In particular, the energy storage device 118 is arranged on the handle device 30.

The energy storage device 118 is in the present case a rechargeable battery 120, for example in the form of a Li-ion battery.

The battery 120 can be detachably connected to a receptacle 122 on the handle device 30, which in the present case is arranged on the lower wall 92. This gives the possibility of charging the battery 120 externally to the cleaning trolley 12. For example, the battery 120 is placed on the receptacle 122 when the cleaning trolley 12 is started up.

Via the energy storage device 118, the charging unit 112 can be supplied with electrical energy to provide and in particular to charge the additional device 14.

The energy storage device 118 is also used to hit other electrical-specific components of the cleaning trolley 12 with electrical energy. These further components include in particular an interaction device 124, sensor devices 126, 128 and 158 and a control device 130. The devices 124, 126, 128, 158 and 130 can be fully or partially integrated into a common device. This device can be arranged, for example, on the handle device 30 or encompassed by it.

In particular, however, the cleaning trolley 12 includes the interaction device 124, which will be discussed below.

The interaction device comprises an interaction element 134 which can be manually operated by a user. The interaction element 134 is used to receive inputs from the user. Input information is transmitted from the interaction device 124 to the additional device 14 and can be processed by the latter.

In the present case, the interaction device 124 is arranged on the handle device 30. As with the receiving unit 78, this offers the advantage that the interaction device 124 is also repositioned when the handle device 30 is attached to a different position on the cleaning trolley 12 or on one of the other cleaning trolleys 100, 200. An additional Interaktionsein direction 124 is not required. The handle device 30 advantageously comprises the interaction device 124.

The interaction device 124 comprises a housing 136 which is inserted into an opening of the base element 48, in particular in the upper wall 90. To rest against an edge of the opening, the housing 136 comprises a flange-like contact area 138. The housing 136 engages in an intermediate space the top wall 90 and the bottom wall 92.

The interaction element 134 is arranged above the base element 48. The interaction element 134 comprises a rotary knob which at the same time forms a push button and a toggle button and accordingly forms a turn-push-toggle button. In the following, the interaction element 134 is referred to as button 140 for the sake of simplicity.

The knob 140 is mounted on the housing 136 so as to be rotatable about an axis of rotation 142. In addition, the button 140 can be tilted relative to the axis of rotation 142 and pressed in the axial direction. The position of the button 140 relative to the housing 136 during rotation, the speed of rotation, a possible tilted position and a pressure on the button 140 can be evaluated by an electrical device 144 of the interaction device 124. Depending on this, input information can be provided by the interaction device 124. The button 140 is arranged on the handle device 30 in such a way that it is arranged in front of the receptacle 80 with respect to an access direction. The receptacle 80, and thus the additional device 14, is arranged behind the button 140 in relation to the direction of access. In this way, the button 140 is not covered by the accessory device 14 and the button 140 can be easily accessed by the user.

The button 140 is arranged between the handle elements 50 and is positioned essentially centrally on the handle device 30.

The additional device 14 is arranged essentially centrally on the handle device 30.

The button 140 is arranged on the handle device 30 that the axis of rotation 142 is inclined relative to the vertical. The angle of inclination is, for example, less than 45 °, preferably less than 30 °. The axis of rotation 142 is inclined in the direction of the user positioned behind the handle device 30.

The button 140 is dimensioned so that it can be easily grasped and operated by the user, especially when the user is wearing a glove. For example, the button has a diameter of approximately 5 cm to 10 cm. A corrugation 146 is preferably provided on an outer circumference of the button 140. The corrugation 146 is formed, for example, by strips and / or by knobs.

When the cleaning system 10, in particular the cleaning trolley 12, is in operation, the button 140 is used to operate the additional device 14. In particular, it is possible to transmit input information to the additional device 14 via an input on the button 140. The interaction device 124 and the additional device 14 can be coupled to one another via a communication connection. The communication connection is preferably wireless. The communication link is preferably bidirectional.

In a preferred embodiment, for example, a Bluetooth-based communication link can be set up between the additional device 14 and the interaction device 124. The input information already mentioned, which is triggered by the user via the button 140, can be transmitted from the interaction device 124 to the additional device 14. Conversely, in a preferred embodiment, output information can be transmitted from the additional device 14 to the interaction device 124.

It goes without saying that the interaction device 124 and the additional device 14 comprise interacting communication devices 74, 141 for setting up the communication connection. As an alternative or in addition to the Bluetooth connection, an NFC connection or a WiFi connection can be used, for example.

The interaction device 124 can comprise a notification unit in order to be able to output instructions to the user as a function of the output information transmitted to it. It is favorable if the button 140 includes or forms the information unit.

In particular, an optical display unit 148 with an image display is provided as the information unit. As an alternative or in addition, for example, an acoustic and / or a haptic information unit can be provided.

For example, images, texts or videos to support cleaning tasks can be displayed on the display unit 148, as explained below. In a different embodiment of the invention it can be provided that the information unit is designed optically, but without an image display. For example, a lighting device with one or more Leuchtele elements is arranged on the button 140 in order to be able to display different colors.

For example, so-called corona lighting is conceivable.

On the additional device 14, a user application program is executable ge stores, which supports the user in the implementation of cleaning. In particular, a cleaning plan with cleaning tasks can be stored in the user application program that are to be carried out by the user.

Via the interaction device 124, there is the possibility for the user to communicate with the additional device 14 and, in particular, to operate this. By actuating the button 140, input information can be released, transmitted to the additional device 14 and processed by the additional device 14 as cleaning-related information for operating the user application program.

Conversely, output information from the user application program can be transmitted to the interaction device 124 and relevant information can be output by the information unit, for example on the display unit 148.

It goes without saying that the display unit 72 of the additional device 14 can output instructions based on output information from the user application program. The acoustic and the haptic information unit can also output information relating to this. Conversely, there is the possibility of providing input information for the user application program via the additional device 14 by actuating the additional device 14, for example by touchscreen, by voice and / or by gestures.

It can be provided that the instructions and / or input options on the display units 72 and 148 are at least partially identical, so that the user can use either the button 140 or the additional device 14 for interaction - output and / or input - with the user, depending on his preference training program.

The button 140 proves to be advantageous, for example, in order to carry out hygienic operation of the user application program even with gloves. By using the button 140, the acceptance of cleaning service providers, customers and third parties for cleaning processes that are carried out with the support of the additional device 14 preferably increases. If the user operates the button 140 instead of the additional device 14, a possible pressure is prevented, the user wasting his time.

Since the cleaning trolley 12 can be used in the dirty environment, it is advantageous if the interaction device 124 is designed to be watertight, at least protected against splashing water and / or dustproof.

The sensor device 126 is designed to identify rooms in which the cleaning trolley 12 is arranged. For example, landmarks 150 are positioned on or in the spaces to be identified. The landmarks 150 are, for example, so-called “beacons” which can be detected and identified by the sensor device 126.

A Bluetooth connection to the sensor device 126 is used, for example, to detect the landmarks 150. The sensor device 126 can be configured, for example, as an RFID reader in order to detect RFID elements. For example, a respective room is identified by an RFID element and can be identified using the RFID reader.

An assignment of the landmarks 150 to the rooms can be stored in the user application program. Depending on which landmark 150 is detected, the cleaning trolley 12 can determine the room in which it is located.

For reasons of data protection law, it can be advantageous if the position of the cleaning trolley 12 is determined and, for example, tracked, but not the position of the user with the additional device 14.

The sensor device 128 is, for example, an RFID reader for detecting RFID elements. It can be provided, for example, that cleaning utensils 152 include an RFID element that is detected with the sensor device 128. In this way, when equipping the cleaning trolley 12, for example, it can be checked that the correct cleaning utensils 152 are being carried. When processing a cleaning plan, it can be checked that the correct cleaning utensils 152 are being used.

By means of the sensor device 128, for example, an RFID element of an authorization holder 154 of the user can also be detected. It can be provided, for example, that the cleaning trolley 12 can only be used if a valid authorization carrier 154 is used. In the absence of authorization, it may be impossible, for example, to release the brakes on the rollers 26. Only a valid authorization enables the user to move the cleaning trolley 12.

As an alternative or in addition to checking the authorization holder 154, it can be checked, for example, whether the additional device 14 has a registered access Set device is and whether the user is authorized to guide the cleaning trolley 12 accordingly. The relevant check can be carried out by a sensor device of the cleaning trolley 12, for example.

Output information from the sensor devices 126, 128 and 159 can be output, for example, via the display units 72 and / or 148 and / or in some other way.

The control device 130 makes it possible, for example, to control information elements on the receptacles 31 for cleaning utensils 152. In the present case, the information elements are designed as luminous elements 156. The light elements 156 can be used to signal to the user, for example, which cleaning utensil 152 is intended and should be used to carry out cleaning. In this way, for example, a "pick by light" system can be provided to support cleaning.

The cleaning trolley 12 can also include the sensor device 158 to. The sensor device 158 is preferably designed to detect a stock of consumables that are carried along with the cleaning trolley 12. For example, this enables the user to be informed about a current or used inventory of cleaning utensils 152. For example, the filling levels of containers 32 and / or the number of existing or used cleaning wipes are recorded.

Information from the sensor devices 126, 128 and 158 can in particular be transmitted to the additional device 14 and processed as cleaning-related information by the user application program. Conversely, information from the user application program to the sensor devices 126, 128 and 158 and to the control device 130 can be transmitted. In the following, with reference in particular to FIGS. 8 to 13, an exemplary mode of operation of the cleaning system 10 will be discussed. In this case, a preferred exemplary embodiment of the method according to the invention is carried out, in which the user can operate the user application program on the additional device 14 via the interaction device 124.

Provision is made in the preferred exemplary embodiment of the method that a cleaning plan is drawn up for the user before cleaning is carried out. The cleaning plan can include several cleaning tasks, for example. At least one cleaning task can be assigned to a room to be cleaned.

The cleaning schedule can include information about rooms to be cleaned.

The cleaning schedule can include, for example, room-related information about objects to be cleaned in at least one room.

The cleaning schedule can include, for example, spatial information about the type of cleaning of at least one object to be cleaned in a room.

Furthermore, the cleaning plan preferably includes information relating to the equipment of the cleaning trolley 12 for processing the cleaning plan.

For example, a plurality of landmarks 150 are installed before a cleaning process, which are assigned to the rooms to be cleaned, with at least one landmark 150 being assigned to each room. Such an assignment can in particular be used for more than just one cleaning process.

For this purpose, for example, a property manager 162 can create a room list, and an installer can set the landmarks 150 on or in the rooms attach (steps S1 and S2 in Figure 9). The assignment of the landmarks 150 to the rooms can be stored in a system memory, for example the data processing device 16 (step S3 in FIG. 9). The relevant assignment is stored in FIG. 8 with the reference numeral 160.

The data processing device 16 can be designed as a single data processing device, for example as a server. However, it is particularly conceivable to use a plurality of computers, for example in a “cloud”.

For a cleaning process to be carried out in which a cleaning plan with at least one cleaning task is provided, the object manager 162, for example, creates a cleaning plan (step S4 in FIG. 9). The cleaning plan is then stored, for example in the data processing device 16 (S5).

It goes without saying that the cleaning plan can also be created directly on the additional device 14 and the data processing device 16 and the object manager 162 can be dispensed with.

The user can load the cleaning plan, for example via the user application program, onto the additional device 14 and save it in the user application program (S6).

In a further step S7, the cleaning trolley 12 is equipped with cleaning utensils 152 for carrying out the cleaning tasks, depending on the cleaning plan. Here, it can be provided, for example, that the cleaning utensils 152 are placed near the sensor device 128, recognized and registered in the user application program. If necessary, incorrect cleaning utensils 152 can be recognized as faulty by the user application program and the user can be informed of this. The user preferably receives an indication when the cleaning trolley 12 is equipped with all the necessary cleaning utensils 152.

In particular during the following steps S8 to S15, the user can repeatedly interact with the user application program via the interaction device 124. For example, inputs are made by rotating, tilting and / or pressing the button 140. Confirmations from the user application program can be displayed, for example, in the display unit 148 (in addition to or as an alternative to the display unit 72). The user's inputs include, for example: calling up the next room for which a cleaning task is stored; a confirmation of which room to clean; calling up information about which object in the room is to be cleaned; an acknowledgment that a certain item in the room has been cleaned; the completion of the cleaning via a corresponding confirmation; calling up cleaning instructions, for example by text or video.

It is possible for the user to be informed of a change in the cleaning schedule via a push message. Changes to the cleaning schedule can be made, for example, depending on the occupancy or accessibility of a room. Push messages can be visualized on the display unit 148 or the display unit 72, for example.

In step S8 the user can call up which rooms are to be cleaned.

In step S9, the user takes the cleaning trolley 12 to the room to be cleaned. In step S10, the sensor device 126 detects that the cleaning trolley 12 is positioned at or in the correct room.

In step Sil, the user application program can be used to indicate which cleaning tasks have to be carried out in the room. The user can be instructed by means of “pick by light” via the light elements 156, for example, which cleaning utensils 152 are to be removed. Corresponding acknowledgments can be made, for example, via the interaction device 124 or directly on the additional device 14.

In step S12, the user cleans the room.

In step S13, the cleaning of the room is confirmed.

If further rooms are to be cleaned, the method is continued at step S8 and repeated for further rooms.

After all cleaning operations have been completed, the user can acknowledge in step S14 that all rooms have been cleaned.

In step S15, the cleaning carriage 12 is reprocessed after cleaning has been completed. Excess cleaning utensils 152 can be removed or a minority of cleaning utensils 152 can be refilled. Waste can be disposed of.

FIG. 10 shows, by way of example, the display unit 72 while the cleaning plan is being processed. Cleaning tasks for rooms 2, 10 and 7 are shown as an example. The cleaning task for room 2 has already been completed.

Room 10 is currently being cleaned. The next step is to clean room 7. Pictograms 164 can intuitively inform the user about which cleaning is to be carried out in detail. For the room 10 there are example, the suction cleaning, cleaning a wet room and emptying a waste container.

The user can acknowledge via the touchscreen of the display unit 72 - by means of a tick or a cross - whether a cleaning task has been completed or not.

FIG. 11 shows a similar situation for the room 10 on the display unit 72 and on the display unit 148 of the button 140. Here, for example, there is the possibility of acknowledging a cleaning task or completing the cleaning task using the button 140.

FIG. 12 shows a similar situation. Here, however, the display of the button 140 has been changed compared to the situation shown in FIG. For example, the user has selected a negative acknowledgment of a cleaning task, for example because it cannot be carried out.

FIG. 13 shows an integration of the pictograms 164 in the display of the button 140. The task selected in each case (cleaning of the wet cell in the example in FIG. 13) is highlighted.

In the example of FIG. 13, the additional device 14 is not received in the receptacle 80, but instead is guided by the user on the body. Here, the additional device 14 is shown by way of example in a pocket 166 of the user.

In a simplified version of the interaction device 124, no information unit and in particular no display unit 148 is provided on the button 140. The button 140 can still be used to navigate through the display of the user application program on the additional device 14. Confirmations can be made. In an exemplary implementation of the cleaning system 10 in practice, the following functions, for example, can be linked to the inputs of the button 140:

For example, confirmation that a room has been cleaned is made by pushing button 140.

For example, a room to be cleaned is opened by pressing the button 140, task descriptions such as "vacuuming the floor, cleaning the surface" etc. can be marked as completed.

For example, the task activity can be opened by pressing it. Here, stored process videos or process cards can be opened.

For example, a floor can be selected by rotating the button 140.

For example, a certain room can be selected first by rotating the button 140.

In particular, further information about the status of the cleaning trolley 12 can be displayed on the display unit 148. For example, it is conceivable to display the remaining capacity of the battery 120, the cleaning time that has elapsed and / or the remaining cleaning time. A stop watch can be provided. Suggestions for route optimization and for guiding the cleaning trolley 12 can be displayed. List of reference symbols:
