Abstract

A cleaning device operated in conjunction with a vacuum cleaner includes a housing which is composed of a motor housing accommodating a drive motor, a removable nozzle plate formed with a first individual nozzle and a second surface nozzle and enclosing a working tool with a brush, and an air-duct housing forming a suction duct connectable to the vacuum cleaner.

Claims

1. In a device for cleaning textile surfaces operable in conjunction with a vacumm cleaner, a combination comprising an electrically driven working tool;

an electromotor having an output shaft connected to said working tool to provide for oscillating pivotal movement of the working tool relative to a surface to be cleaned and a housing including a drive motor casing, a nozzle casing and an air-duct casing, said nozzle casing being formed with a first nozzle and a second nozzle, said second nozzle accommodating said working tool, said air-duct casing including a connection element having a suction duct connectable to the inlet of the vacuum cleaner fan, said nozzle casing being formed with a first suction channel communicating with said first nozzle and a second suction channel communicating with said second nozzle, said first suction channel and said second suction channel being selectively open into said suction duct, and said connection element being a grip, said working tool being formed with a projecting tip, said nozzle housing including two projections spaced from each other to form a gap therebetween, said tip being positioned in said gap to provide an axis about which said pivotal movement occurs.

2. The device of claim 1, said nozzle housing having a lower surface, said drive motor casing having a lower surface, the lower surface of said drive motor casing extending above said lower surface of said nozzle housing.

3. The device of claim 2, wherein said drive motor casing is provided with openings for motor cooling.

4. The device of claim 3, said drive motor casing having a wall facing said connection element, at least one of said openings being formed in said wall.
