By specifically applying extremely high water temperatures, weeds, moss, algae, and organic contaminants can not only be visibly removed, but also damaged at the root level. This method leaves no residues and places no burden on soil or groundwater. It is ideal for sensitive areas such as playgrounds, schoolyards, parks, or heritage sites.

Unlike chemical herbicides, hot water has an immediate effect. It is biologically neutral, completely residue-free, and meets the highest ecological standards. Our equipment requires neither special protective clothing nor complex approval procedures. This is a clear advantage for professional use in sensitive environments.
