Photo 8 for Intex Pure Spa Hot Tub Pool Water Heater Circulation Pump SSP-H-10-1

I currently have a SSP-H-10; do you know the difference between this and the SSP-H-10-1? I see the wattage for the "Bubble" is 800W rather than 650W, but what else is different? Also, it says "water pump" only; I assume this means the "whole lower unit" or "control base" (and not the "control panel"); is that correct. The control base has more than just a water pump in the assembly, such as circuit board, heater, etc.
