Are the massages motorized?
Please kindly be noted that these massager rollers are not motorized, please move your feet to enjoy the roller massage of your soles.
Does it heat up on its own?
The foot spa does not heat up on its own due to the portability of it. It is more efficient to put hot water in a foot spa anyway.
How long does the water stay hot?
It depends on the temperature of the water you put in. But on average the Foot Spa Massager will stay hot for up to 40 minutes because of the low heat dissipation material.
