Abstract: An improved mechanism for moving a wiping/raising insert of a suction nozzle for a vacuum cleaner is described. The suction nozzle comprises a base plate. The mechanism for moving the insert comprises an operating pedal and a frame for supporting the insert and for bringing this insert from a first working position into a second rest position. The pedal is rotatable about a first axis of rotation and the frame is rotatable about a second axis of rotation. According to the invention, the first and the second axis of rotation lie in a plane inclined at an angle ? ranging between 80° and 100° with respect to a plane of the base plate.

Abstract: A suction nozzle (otherwise called “brush”) for sucking up dust and/or fluids and/or waste from a surface is described. The suction nozzle comprises a base plate with at least one channel open towards said surface, a suction duct in fluid communication with the at least one channel of the base plate and a body associated with said base plate. According to the invention, the suction duct is produced as a component separate from the plate and the body. Connection means are also provided for connecting the suction duct to the body and/or to the base plate. Owing to the present invention, more efficient suction ducts which produce less noise than the known ducts may be produced.

Abstract: A device for removing dust and rubbish includes a casing provided with a suction opening, a rotating brush, a turbine operationally connected to the brush, a suction nozzle located between the brush and the turbine, and a suction pipe connected to a suction device; the brush and the turbine are rotatably supported, respectively, in a first and in a second housing; the device also includes at least a bypass duct and a first valve, the bypass duct being designed for bypassing the second housing and the turbine, the first valve being able to engage with the suction nozzle and with the bypass duct for closing the suction nozzle and opening the bypass duct.

Abstract: A turbo-brush for cleaning a surface includes a casing provided with a suction opening, a rotating brush, a turbine which has a rotor provided with vanes and is operationally connected to the brush, a suction nozzle and a suction pipe connected to a suction device; the casing has a housing inside which the turbine is rotatably supported for rotating about an axis of rotation; the suction nozzle is located between said brush and said turbine for sucking an air flow from the suction opening, direct it onto the brush and then towards the turbine; the housing of the turbine has at least one lip projecting to a distance from an outer end of the vanes of the turbine which ranges from 0.001% to about 0.1% of the diameter of said rotor of said turbine.
