An air broom for suspension from the hand of the user while standing wherein a power unit and an air impeller connected to and driven thereby support an outwardly extending hollow wand whose weight and leverage are coordinated with that of the power unit and air impeller so that the wand is cantilevered at an outward and downward angle with its remote end adjacent the ground. The apparatus is designed for flowing with a sweeping action and for gathering with a suction action.

An air broom system comprising: a housing, a portable power unit in said housing and having a rotary power output with a longitudinal axis of rotation, a rotary air impeller in said housing connected to said power output for rotation thereby, said housing having an air inlet and an air outlet in flow communication with said air impeller, an elongated tubular wand having an end in flow communication with one of said inlet and outlet of said housing and extending outwardly therefrom, said housing having a carrying handle at an upper portion thereof and from which the housing with said power unit and air impeller, and said elongated tubular wand are suspended with the longitudinal axis of rotation of the motor generally upright, the weight of the housing, power unit and air impeller, as an entirety, relative to the weight and leverage of the outwardly extending tubular wand, being such that the wand extends outwardly and downwardly toward the ground and terminates close to, but above the ground when the air broom system is held by the handle in operation by a standing person, said handle and wand being distinctly separate and extending from opposite ends of the housing along the rotational axis of said motor.
