Vacuum cleaner suction stream modification device - provides deliberate blocking of suction stream for increasing suction pressure when released

摘要

The vacuum cleaner suction stream modification device is positioned in front or within the suction jet, or in the path of the suction stream to the suction side of the fan and allows the suction stream to be interrupted for a variable interval for increasing the reduced pressure, when released. The device can be operated at timed intervals with full or partial closure of the suction stream, to allow a pulsating or beat suction current to be obtained for increasing the cleaning effect for a heavily soiled surface. ADVANTAGE - Improved heavy duty cleaning.
