Dual Moto Jet assembly in cool grey is for 2005 to current Hot Spring Spas.
The Moto-Massage is a jet that automatically travels up and down to massage a person's back. The mixing of air and water in a jet along with a playable spine causes the sweeping motion of the Moto-Massage. The intensity and speed of the Moto-Massage can be adjusted with the air control valve. The Moto-Massage is curved to fit the curvature of the back.
The Moto-Massage consists of a jet nozzle, water tube, threaded fitting, vertebrae and an air tube with an o-ring. The Moto-Massage is held in place by a special recess behind the spa shell. A shim is used to assist in proper movement of the Moto-Massage.
