ABSTRACT:
A vacuum cleaner hose having an electrical conductor for a motor driven work tool. The hose includes an inner and outer tube having a spacing therebetween which has been so chosen as to permit the electrical conductor therein to move relatively freely therebetween. The desirable result of the construction is that the vacuum cleaner hose is easier to handle and bend and at the same time the electrical conductor is carried within the hose and is not subject to the exposure of bare conductor wires due to wear.
