<p>This invention relates to vacuum cleaners which may be in the form of so-called upright and cylinder cleaners. In the vacuum cleaner according to the invention the functions of air movement and rotation of a rotary beater or brush are separated. This results in a more flexible product, less possibility of damage to a belt driving the beater and gives a ready means for stopping the beater when the cleaner is parked. In more detail, the vacuum cleaner comprises a main body (4), a first portion (6) and an electric fan housing (12) coupled to a first aperture (36) of an air duct (10), the first portion (6) including a suction opening (27) adjacent a beating means (20), a turbine (14) coupled to a second aperture (23) of the air duct (10) and a drive line (26) coupling between the turbine and the beating means, whereby cleaned air is directed through the duct to the turbine. <IMAGE></p> |
