  • the proposed method is carried out using a base station for a cleaning device.
  • a base station within the meaning of the present invention is a constructive, preferably stationary or non-movable device for vacuuming or emptying a preferably mobile cleaning device, such as a hand-held vacuum cleaner and/or a self-propelled vacuum cleaner robot, after a cleaning process, in particular automatically or automatically.

  • a base station within the meaning of the present invention has a fluidic or pneumatic connection for the cleaning device, a container for suction material and an optional fan downstream of the container in order to convey suction material from the cleaning device into the container of the base station during a suction process .
  • the base station is optionally equipped with a collection filter, in particular a filter bag, which is arranged in the container of the base station.
  • a cleaning device within the meaning of the present invention is preferably a vacuum cleaner, for example a hand-held vacuum cleaner, a vacuum cleaner that can be moved in particular, a trunk vacuum cleaner, a stick or handle vacuum cleaner or a (partially) autonomous or self-propelled or self-flying vacuum cleaner robot, hereinafter referred to as robotic vacuum cleaner.
  • a vacuum cleaner for example a hand-held vacuum cleaner, a vacuum cleaner that can be moved in particular, a trunk vacuum cleaner, a stick or handle vacuum cleaner or a (partially) autonomous or self-propelled or self-flying vacuum cleaner robot, hereinafter referred to as robotic vacuum cleaner.
  • a cleaning device within the meaning of the present invention can also be another device for cleaning and/or maintaining surfaces, in particular floors.
  • a cleaning device within the meaning of the present invention can also be another device for cleaning and/or maintaining surfaces, in particular floors.
  • lawnmowing devices or robots are also to be understood as cleaning devices within the meaning of the present invention.
  • a cleaning device within the meaning of the present invention preferably has a chamber in which suction material can be accommodated during a cleaning process by means of the cleaning device.
  • the cleaning device can be connected to the base station after use or after a cleaning process in order—in the case of a battery-powered cleaning device—to charge the cleaning device, preferably automatically or automatically (electrically) and/or—in particular to charge the chamber of the cleaning device - To empty or suck out preferably automatically or automatically during a suction process.
  • the base station is consequently preferably designed to suck suction material from a cleaning device into a container of the base station during a suction process.
  • the container or the collection filter fills with suction material. Therefore, the flow resistance through the container or the collecting filter also increases with each suction process, so that only a reduced dynamic pressure can be built up downstream of the container by means of the blower. Consequently, the dynamic pressure or the differential pressure to the (immediate) environment can be used as an indicator for the amount of suction material in the container or collection filter.
  • the cleaning device As the filling level increases or the differential pressure decreases, the cleaning device is not sucked out or is no longer sufficiently sucked out. If the determined differential pressure reaches or falls below a (critical) - empirically determined and electronically stored - limit value, a predefined filling level of the container or one corresponding to the limit value has been reached and/or the container or the collection filter is full or almost full, so that the container emptied or the collection filter needs to be changed.
  • the base station (precisely) has a pressure sensor, preferably with the pressure sensor in particular immediately downstream of the container or the collection filter or the fan and/or in the flow channel between the container or the collection filter or the fan and an outlet opening of the base station, in particular around the (static) pressure, preferably the absolute pressure or the differential pressure to the (immediate) environment, downstream of the container or the collecting filter or the blower and/or in the flow channel between the container or the collecting filter or to measure or determine the fan and the outlet opening.

  • the fill level of the container determined in this way is preferably communicated or displayed to a user—in particular during and/or after a suction process. For example, it is possible to show a user or to notify you when the measured differential pressure reaches or falls below the limit value and/or the container is full or almost full and needs to be emptied or the collection filter needs to be replaced.
  • a differential pressure measurement is carried out using the pressure sensor of the base station or the differential pressure to the (immediate) environment is determined in order to determine the fill level of the container in particular solely on the basis of the differential pressure.
  • the differential pressure is preferably the difference between the dynamic pressure or the (static) absolute pressure (directly) downstream of the container, in particular (directly) downstream of the blower, and the ambient pressure.
  • the ambient pressure is preferably the (static) absolute pressure or air pressure or atmospheric pressure in the (immediate) vicinity of the base station.
  • the proposed method is characterized in that when a predefined filling level of the container or the collection filter is reached or when a (critical) limit value is reached or undershot, the maximum number of suction processes that are still possible using the base station without emptying the container or changing the Collection filter is limited, in particular the (further) operation of the base station is automatically blocked when the maximum number of suction processes with the container or the collection filter in the predefined filling level is reached without emptying the container or without changing the collection filter.
  • the predefined fill level is reached, for example, when more than 80% or 90% of the container or the collection filter is filled with suction material.

  • a user is preferably shown or informed that the predefined fill level of the container has been reached and/or only a certain number of suction processes with the container is possible without emptying or changing the collection filter.
  • a renewed suction process is preferably carried out only by a (manual) user input.
  • a renewed suction process is only possible with a (manual) release by the user when the maximum number of suction processes with the container in the predefined fill level has been reached and/or the operation of the base station has been (automatically) blocked. This reduces the risk of (accidentally) operating the base station with a full tank or collection filter.
  • the pressure sensor or a (repeated) pressure measurement is used to check whether the container has (actually) been emptied or the collection filter has (actually) been changed, in particular by the fact that the differential pressure to the environment (again) is determined or measured and evaluated or compared with the limit value.
  • the operation of the base station is preferably blocked (again) automatically if the differential pressure is not above the limit value or the container has not been emptied or the collection filter has not been changed. Provision is therefore made for the user input to be verified by means of the pressure sensor or a (repeat) pressure measurement.
  • a pressure sensor within the meaning of the present invention is a measuring device to measure or determine the (static) pressure in a medium such as air.
  • a pressure sensor can be designed as an absolute pressure or differential or relative pressure sensor.
  • An absolute pressure sensor measures the (static) pressure compared to a vacuum as a reference (absolute pressure), preferably a vacuum being at a pressure of less than 300 mbar.
  • a differential pressure sensor measures the difference between two absolute pressures (differential pressure).
  • a relative pressure sensor measures the (static) pressure in comparison to the atmosphere/surroundings or to the atmospheric air pressure, preferably with the atmospheric air pressure being 1013 mbar.
  • a relative pressure sensor within the meaning of the present invention is consequently a differential pressure sensor that measures the difference between an absolute pressure and atmospheric air pressure.

  • a pressure sensor within the meaning of the present invention can be designed, for example, as a piezoresistive, piezoelectric, capacitive and/or inductive pressure sensor.
  • the proposed method it is possible to increase the absolute pressure downstream of the container or the fan or in the flow channel between the container or the fan and the outlet opening before the suction process or with the fan deactivated and additionally during the suction process or with the fan activated measure to then determine the differential pressure.
