In conjunction with a pool cleaning apparatus having a flexible hose supported by floats, an apparatus for deploying the hose into the pool includes at least one tube through which the hose extends. A cylindrical water jet discharges into the tube toward the outer, pool end of the tube. The jet interact with the floats to drive the floats and the hose into the pool. A donut-like pressure chamber at the inner end of the tube has an annular vent to create the cylindrical water jet.
