How much horsepower on the jets?
Hello and thank you for your inquiry.
The lower priced inflatable hot tubs have air bubbler jets and that is simply air blown into the water and it bubbles to the surface.
This creates the water action.
There is only one model of inflatable that has actual water jets and that is this one, with 8 water jets.
Based on typical 110 volt hot tubs, I would estimate it to have about a « HP water pump on it.
