Abstract (en)
A suction device that uses a semi-closed circulation system that causes both suction and blowing action across an opening in the fluid flow generating device head or suction component. The blowing agitates dirt/dust from the surface to be cleaned and is sucked back around the semi-closed loop which brings the dust into a separator or fluid cleaning system where dirt/dust is separated and cleaned and re-circulated through the system through the blowing inlet repeatedly. This provides increased efficiency and reduced power consumption while providing more effective cleaning.
