It’s basically a foot spa. Nothing big. Here is some information I looked up for you:

However, none of Japanese manufacturers claim that it can do detoxification through feet. They just claim that it can help in rejuvenating your health, removing fatigue and other stress-oriented illnesses (e.g. neuralgia, rheumatism, lumbago, poor blood circulation, hemorrhoids, fatigue, dry skin, bruise, frostbite, chapped hand, miliaria (heat rash), allergies, pimples, migraine, insomnia, headaches, sinusitis, stiff neck and shoulders, sport injuries).

The recommended temperature is 40-42 °C, and time duration of about 10-25 minutes per treatment. You can do it many times as you desire.

*The Truth on Foot Detox*

Is foot detox really true? Actually, there is no definite medical proof about foot detox. Our own research also indicates either “Yes” or “No”. Whatever the results of our researches, it is true that foot detox with minerals or herbs or electrodes added, will help in relieving fatigue and stress, and energize the body system, leading you to good health.

Also, our own research indicated that foot detox does not clean your body’s wastes or toxic wastes as others claim. The public may be swayed by the water “miraculously” turning brown or black in color. However, it’s proven that the changes in color are caused basically by the “electrolysis” of water.

And most of them claim that foot detox machines:
