Abstract: A pool cleaner having a sweep tail hose has a deflector at a downstream or discharge end thereof, wherein the deflector comprises a relatively flexible structure in comparison with the sweep tail hose. During normal submerged operation as the pool cleaner and sweep tail hose travel over submerged pool floor and side wall surfaces, water jetted from the sweep tail hose flows substantially without restriction through the deflector. However, when the discharge end of the sweep tail hose breaks the surface of water within the swimming pool, the relatively flexible deflector falls by gravity over the otherwise open discharge end of the sweep tail hose to deflect water jetted therefrom. Accordingly, the deflector effectively knocks down and prevents water jetted from the sweep tail hose from spraying over any significant distance or area of a surrounding pool deck region.
