The Heatweed Mid 22/8 has been specifically developed as a weed machine, but is also an excellent solution for cleaning of façades, benches, signs and gravestones.

The very high, stable water temperature ensures a short drying time, as well as lower water and energy consumption compared to hot-water washers. Algae, dirt and oil are more easily removed with the extremely hot water.
