Abstract
Abstract A vacuum cane for picking up articles off the floor is provided and consists of a hollow cylindrical cane-shaped housing having a curved hand grip, an electric fan affixed vertically within the housing near the hand grip to provide suction for the vacuum cane, a battery within the housing to supply power to the electric fan and an inverted cup affixed to bottom of the housing. The cup creates a seal around its periphery so that a vacuum is created applying suction of a small area to a large area when placed against the article to be picked up off the floor.
