Abstract: To remove particles of debris from a floor surface, a hood is mounted on wheels to move over the floor with the open side of the hood facing downward to form a traveling chamber. An air jet nozzle inside the hood is directed downward and is moved in a circular horizontal orbit by a variable speed motor to agitate the debris particles as the hood travels. A pump is attached to the hood to maintain a vacuum therein and to withdraw from the hood a high velocity air stream entraining the agitated debris particles. The hood is manually steered and is driven by a variable speed motor.
