A cleaning device for cleaning spas by removing particulate debris siphons liquids from the spa so that the debris is sucked out of the spa by the fluid flow. The device includes a rigid handle portion, an upstream nozzle and a downstream hose having a discharge outlet to define a fluid passageway. Preferably, the nozzle and hose are formed of a continuous piece of thermoplastic tubing having an upstream end molded into the nozzle configuration, and the handle is a rigid thermoplastic tube telescopically receiving a portion of the hose adjacent the nozzle. A protector sleeve retards mechanical fatigue of the hose at the downstream edge of the handle. Preferably the nozzle has an ovoid inlet both canted at an acute angle to the handle\s longitudinal axis and formed contiguously with an imaginary concave surface so that the inlet describes an arch when placed on a flat surface.

A siphon device adapted to remove particulate debris from a spa by utilizing siphoned liquid to convey the debris out of the spa, as the liquid flows to a waste location, comprising: an elongated, relatively rigid tubular handle having a longitudinal passageway operative to convey liquid from an upstream end to a downstream end thereof; a nozzle having a surrounding sidewall defining a nozzle outlet in fluid communication with said passageway at the upstream end of said handle and having an ovoid nozzle inlet formed by a rim of said nozzle at an upstream end thereof, said rim being contiguous on an imaginary concave surface with respect to said nozzle, said nozzle being formed of a pliable material; and a flexible hose having a hose inlet in fluid communication with said passageway at the downstream end of said handle and having a discharge outlet opposite said hose inlet whereby liquid may flow into said nozzle, through said passageway and said hose and be discharged at said waste location.
