Semi-automatic greenhouse roof washer

In the semi-automatic version of the Roofmaster, control takes place via a touchscreen. Settings such as the start and end time or the number of rows to be washed are clearly displayed and easily adjusted.

Wash greenhouse cover

When you give the start signal to the roof washer via the touchscreen, the water pump starts and the system starts washing the greenhouse roof. After cleaning, the Roofmaster automatically moves to the next peak via the service rail. This continues until the set program is completed.

From smartphone

One of the advantages of a semi-automatic greenhouse roof washer compared to the manual version is the practical app. With this tool you can easily operate the Roofmaster from your smartphone, tablet or desktop. With the remote access function you always have control at hand and you do not need to be present at the Roofmaster yourself.


Growers grow different crops, have different greenhouses and all have different wishes when it comes to greenhouse roof washing. For this reason every Roofmaster we build is different. Since we develop all components in-house, even the most challenging customization is no problem for us. Every Roofmaster including platform and accessories is tailor-made, installed on site and adjusted. Everywhere in the world.
