<p>Detailed are fluid flow deflectors (38, 138) for use with sweep tail hoses (18) of automatic swimming pool cleaners (10).The deflectors (38, 138) do not function principally on gravitational forces and need not necessarily employ flexible components or attachments for purposes of effecting deflection. Instead, the deflectors may be rigid and continually position a fixed obstacle (82) in a central portion of a fluid stream. Perforations (62) in a rigid wall (46a), moreover, draw fluid into the deflectors (38, 138), creating a greater volume of exiting stream when an associated pool cleaner (10) is underwater.</p> |
