Abstract
A cleaning device for swimming pools comprising a specially shaped propelling head attached at the end of a flexible hose supplied by water under pressure. Water ejected rearwardly through ports surrounding the attachment of the head to the hose drives the head forward. The whipping action of the hose encouraged by jets spaced along the length of the hose produces a random trajectory over the entire bottom of the pool so that effective agitation and cleaning is achieved over the total pool area.
Claims10
A cleaning device for swimming pools comprising:
- a generally conical shaped housing comprising a first portion forming the tip of the housing and a second portion the base of the housing,
- said base portion defining a first fluid conduit arranged axially along at least a part of its length which is open at the base of the base portion for connection to an elongated flexible conduit which is connectable to a source of water under pressure,
- said base portion further defining a plurality of second fluid conduits spacedly arranged around said first fluid conduit,
- one end of each of said second fluid conduits terminating in a nozzle adjacent the base of said base portion, and
- means for connecting the other end of said first fluid conduit with each of the other ends of said second fluid conduits interiorally of said base portion,
- whereby water under pressure passing through said first fluid conduit from said one end to its other end thereof and through said second fluid conduits causes said cleaning device to move through the water in a swimming pool while dragging the flexible conduit behind it.
