Abstract
An expandable hose is provided formed of a sidewall formed of a spirally wound flexible member which defines an axial passageway surrounding a center axis of the formed hose. Both side edges of the flexible member in the spirally wound position are engaged with a cap member which provides a skeletal structure to maintain the axial passageway open and to bias the hose back to a collapsed length from the extended length. A fold formed in the spirally wound flexible member allows for increased distance between the two side edges and an increased maximum extended length. A telescopic pole engaged with the formed hose provides an improved extendable vacuuming tool.
