Abstract:
A vacuum cleaner head (70) comprising:a housing (71) having a turbine chamber (2) and a connection tube (78) connecting said turbine chamber (2) to a suction aggregate of a vacuum cleaning machine;said housing (71) having a suction opening (73) and said turbine chamber (2) having an inflow opening (12) communicating with said suction opening (73), wherein air flow is sucked in by the suction aggregate through said suction opening (73) and said inflow opening (12);a rotary roller brush (74) mounted in said housing (71) close to said suction opening (73) such that bristles (75) of said roller brush (74) project outwardly through said suction opening (73) when said brush is in a lowest position;an air turbine (3, 40, 50, 60) mounted in said turbine chamber (2) such that said air turbine (3, 40, 50, 60) is acted upon by said air flow (20) passing through said inflow opening (12);means for axially displacing said airturbine (3, 40, 50, 60) relative to said inflow opening (12) when the power uptake of said roller brush (74) is reduced.
