The patented vacuum bag from Hagleitner is 60 percent lighter than standard soap refills. As the contents of the vacuumBAG empty, the bag shrinks to about ten percent of its original volume. A standard waste container can hold over one million vacuumBAGs. As a result, up to 95 percent less waste is generated than with comparable products.

A refill dispenses up to 2,000 doses of foam soap.

The XIBU FOAM analog has a viewing window onto the reserve tank. When the level here drops, it means: The refill has been used up and will soon need to be replaced with a new one.
