If the suction unit is moved away from the dirt collecting container, that is to say it takes up the change position, the dirt collecting container can be removed, for example, from a dirt collecting container receptacle of the carrier. If the dirt collecting container receptacle extends to a surface on which the carrier is also arranged, the dirt collecting container can, for example, be designed like a trolley which is simply moved sideways out of the dirt collecting container receptacle.
  • the operator does not even have to lift the dirt collection container, but can easily slide it on the surface.
  • the carrier comprises, for example, a support frame and / or a housing.
  • a self-supporting housing which carries the suction unit is particularly preferred.

  • connection unit it is possible for the connection unit to be adjusted, for example, to the side of the dirt collecting container in the operating position and to the side of the dirt collecting container in the changing position.
  • actuation from above is preferred, ie that the connection unit is arranged further down on the carrier in the operating position than in the change position.
  • the connection unit is thus moved downward into the operating position in order to establish contact or a flow connection to the dirt collecting container, or is moved upward again (change position) in order to release the dirt collecting container.
  • connection unit can be driven manually and / or by motor between the operating position and the change position.

  • the backdrop follower can e.g. comprise an inclined surface.
  • a link follower of the link arrangement can, for example, be stationary with respect to the carrier and can comprise, for example, a wheel, a rolling element, a sliding element or the like, along which the at least one link slides along the link arrangement.
  • the at least one link is therefore preferably stationary with respect to the connection unit.
  • at least one link that is stationary with respect to the carrier is provided, while the link follower is stationary with respect to the connection unit
  • the aforementioned wheel is preferably rotatable by means of a ball bearing, roller bearing or other roller bearing with regard to its connection to the carrier or the connection unit
