Title: Air broom

What is claimed is:

1. 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.

2. The structure in claim 1, and said handle, when the system is suspended, having a hand grip portion on a substantially horizontal axis.

3. The structure in claim 1, and a control for said power unit located in the area of said handle.

4. The structure in claim 1, and said tubular wand having a flexible end portion.

5. The structure in claim 1, and said tubular wand having a flow connection with said housing air outlet, and said housing air inlet being open to atmosphere.

6. The structure in claim 1, and a dust trap suspended from said housing and having an outlet flow connection with the air inlet portion of said housing,

said dust trap having an air inlet,

and a connection between said elongated hollow wand and said dust trap air inlet.

7. The structure in claim 6, and a filter in one of said air inlet portion of said housing and said dust trap.

8. The structure in claim 6, and said dust trap having an enclosed interior flow passage between its air inlet and its outer flow connection with said housing, and said dust trap having means in said interior flow passage intercepting and diverting air flowing in said passage from a direct path between the air inlet and the dust trap and its outlet flow connection.
