ABSTRACT:
A brushing apparatus for carpets and the like has a housing one side of which faces a surface to be brushed and is provided with a plurality of wall portions connected with one another by weakened hinge-like zones so that these wall portions are produced in flat condition and can then be displaced relative to one another to a condition in which they define a trough. A brush extends along the trough and, when rotated in response to movement of the brushing apparatus over the surface, picks up dirt and deposits it in the trough.
