Abstract: A hose construction adapted for efficiently conveying fluids while extended, but capable of neatly contracting to a fraction of its extended length for storage or transportation, while integrally incorporating lines for electrical requirements. Storage may be within an outer hose and may be triggered via closure of a valve within a nozzle so that negative pressure causes contraction of the folds of the hose. The contracted hose has a length that is a fraction of its normal extended length. The hose construction incorporates a wire reinforcing member which may bias the hose for self-extension and may also function as part of the electrical system. The electrical lines may comprise stranded copper wires to conduct power and/or serve as a remote activation circuit. The hose configuration may have a cover with external folds, which maximizes flow and provides a cushioning outer diameter to prevent damage to the hose.
