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.
