HydroMax mimics the effect that is achieved during a natural erection in the way that it draws blood into the Corpora Cavernosa, the  erectile tissue of the Penis.

This is done by using water to create a vacuum instead of air, the more that water is forced from the product the more the penis is forced to expand safely and the higher the hydro force vacuum becomes within.

The water vacuum exercises the penis and forces blood through the veins making it easier for these veins to carry more blood in future, which can be beneficial to those men who have experienced erectile dysfunction due to vascular problems.

Standard air vacuums create a vacuum that prevents the reversal of blood from the penis. HydroMax is different due to the fact that the vacuum is only present for one to two seconds at a time. There is a release of vacuum twenty to thirty times in a single session.
