ABSTRACT:
In a cannister or tank type vacuum cleaner which uses a generally cylindrical filter element that is fitted around a generally cylindrical filter cage, the cage is an integral plastic molding with the lid that closes the tank of the vacuum cleaner; the vacuum cleaner motor sits atop the lid; the lid is removably sealed to the cannister; inside the filter cage, there is a freely floating ball, which floats up through the cage as the tank becomes filled to seal the air outlet to the motor.
