Vacuum cleaner head including insufflation and pulling fans

Abstract

Embodiments include a vacuum head portion and a combined suction and blowing mechanism configured to agitate and remove debris. A set of powered fans provide an external pressured air source to provide pressured air for the blowing mechanism. The vacuum head portion may include blowing and suction nozzles arranged with the blowing nozzles flanking the suction nozzles. The set of powered fans may be driven an electric motor or via air turbines disposed in an air stream of the suction nozzles. The blowing nozzles may be in parallel rows adjacent to the suction nozzles. The blowing mechanism may be operated to act as a suction device by reversing the rotational direction of the set of powered fans via a switching mechanism to create a negative pressure or suction to assist the suction nozzles. The vacuum head portion may be formed as a removable detachment to the vacuum cleaner.
