Abstract

Vacuum cleaning apparatus having air flow generating means to generate an airflow from a nozzle means to a receptacle to entrain dirt and debris and to transport said dirt and debris to the receptacle for collection and ultimate disposal, in which the air flow generating means is a fan driven by electric motor which latter is rated to produce a fan rotation speed greater than 24,000 rpm and a fully open air flow of greater than 3 m<3>. In a particular aspect of the invention the effect is to use a smaller motor and make it work much harder and faster in order to achieve a given air flow performance and then providing corresponding insulation around the motor to reduce the noise therefrom to below 50 dba.
