  • it turns out the replacement of the care coverings as very time consuming and unhygienic, because if the coverings are removed the User in contact with the dirty surfaces comes.
  • a combination care disc is given, among other things, which has a coating on both sides. Consequently common types of flooring, e.g. to the Polishing or polishing or cleaning and soft cleaning in only one care disc can be integrated. By simple If the care disc is turned by 180 °, the corresponding one comes Type of covering used.

  • the support shape of the care disc according to the invention serves both to support the care disc on a drive shaft as well as on a centering shaft for the not directly driven care discs.
  • This also applies to a design of a floor care device the possibility with several care discs given this due to their identical design to exchange with each other.
  • This has the other Advantage that the user when loading the Device with the care discs not to a specific one Assignment of the care discs to the individual shafts must pay attention.
  • the arrangement of the care discs on the Floor care device is contrary to the known state the technology not by means of latching or the like, but here it is rather the case that the care discs a hemispherical, axial on both sides have arranged support formation, in which the respective, correspondingly shaped end face entry.
