Swimming pool bottom cleaning device

摘要

A swimming pool bottom cleaning device includes a cleaning head (1) fitted with an alternately suctioning valve arrangement and provided with an elastic sliding base (2) being freely rotatable in its plane. The valve arrangement includes a freely moving, ball-shaped valve member (3) and a second valve member being formed by a piston (6) with a Venturi arrangement. These two valve members are related to each other by an articulated shaft (9 and 10) and are thus fit to alternately act on the main suction pipe (5) and on the tubular attachment (7) being laterally connected to the main pipe. The sliding base (2) has a generally triangular shape as well as transversal folds (14) being provided in the coma regions (13) and an upwardly extending skirt (15) being provided around its periphery.
