Brush attachment for vacuum cleaners

Abstract

A brush attachment for vacuum cleaners comprises a housing consisting of a bottom part and a top part, a turbine wheel driven by the suction air stream, a brush roller driven by the turbine wheel, and a suction tube connection constructed in the form of a swivel/tilting joint. The brush roller is disposed in a brush roller chamber which has a bottom opening constructed as a suction orifice. The turbine wheel is disposed in a turbine chamber with a connection duct of the swivel/tilting joint. The duct is pivotable about the turbine wheel. The bottom part of the housing has webs which form the back wall of the brush roller chamber and the side walls of the turbine chamber and define a flow chamber. A nozzle made as a separate part is inserted in the flow chamber and contains an incident flow duct for alignment of the suction air stream flowing against the turbine wheel. The top part of the housing has connection webs which bear against the webs and against the top of the nozzle.
