  • Another object is to make the rotatable cleaning roller so that long fibers and especially hair, as well as animal hair, are reliably absorbed.
  • the rotatable cleaning roller has a central shaft and on the shaft a plurality of bristles is arranged in at least one row.
  • the bristles are fastened in tufts on the shaft or in the shaft.
  • each row of tufts is assigned at least one flexible web, the web being mounted radially projecting on the shaft.
  • the attachment can be made in a form-fitting or cohesive manner, for example by providing a groove in the roll or by gluing.
  • the web is disposed immediately adjacent to a series of tufts and in particular extends only over part of the height of the bristles, such that the web contacts and supports the tufts - in particular in its lower region - from one side. In other words, the bristles protrude radially over the bridge. Due to the fact that the web rests on the tufts of bristles, the bristles are pushed in a row side by side, that a continuous bristle strip is formed with a continuous sweeping line. This ensures advantageously that bristles

  • the flexible sweeping lip can be made of an elastomer or of a rubber.
  • the provision of such a flexible sweeping lip between two rows of tufts advantageously contributes thereto in that dirt particles, namely longer fibers, are not wrapped around them during rotation of the rotatable cleaning roller.
  • the at least one row of tufts and / or the at least one web extends substantially over the width of the roller. Thus, there are no spaces through which dirt particles could pass.
