The single-stream specification on the Hot Spot® SX and TX is one stream of water sweeping up and down the back, distinguished from the dual-stream Moto-Massage® DX on the Highlife® Series which delivers two streams simultaneously.
The SX jet stack includes 1 Moto-Massage® Jet, 1 XL Rotary Hydromassage, and 16 Directional Precision® Jets. The TX jet stack includes 1 Moto-Massage® Jet, 1 Directional Hydromassage, 1 Rotary Hydromassage, and 8 Directional Precision® Jets. Both models include the signature Moto-Massage® seat in their seating layout.
Within the Hot Spot® Series, the SX and TX are the two models that carry the patented moving jet. The other four Hot Spot® models (Pace™, Rhythm®, Stride®, Relay®) do not include the Moto-Massage® jet.
