ABSTRACT:
An upright-type vacuum cleaner wherein the air pump, traditionally fixed to the bottom motor shaft, is repositioned at the top of the motor shaft and the dirt-laden air duct is directed up over the motor to this top mounted air pump, and a radical change of direction is introduced in the air duct to cause heavy debris fragments, that would normally enter and damage the air pump, to drop out of the incoming air stream into an emptyable receptacle.
