Dirt also builds up quickly on a new greenhouse. One or more showers of rain will not make a difference.
Vegetable growers clean their greenhouse 5 tot 15 times a year. Every percent of dirt means production loss! By brushing the glass on a regular basis, you also prevent weeds and moss from growing onto the greenhouse gutters.
No, a Top Cleaner is custom-made for 1 peak width. The Safety-Cart is suitable for different peak widths though.
Yes, rails are necessary to ride a roof cleaner from peak to peak by means of a movement platform.
The total weight depends on the type of chosen options. In most cases, the weight is between 400 and 500 kg. A total weight of 600 kg is often allowed for new greenhouses. Please consult the builder of your greenhouse.
The standard for new greenhouses is that rails should be able to carry a weight of 1,800 kg (roof cleaner + platform + two persons).

Please ask your supplier. The needed amount of spray liquid (coating + water) per hectare is about 1,300 litres.
The supply depends on multiple factors; the water pressure of the nozzles, the riding speed of the machine and the size of the nozzles. Please don't hesitate to ask us, because we would love to help you calculate the right amount.
Yes. Not every pump is suitable. Van der Waay provides pump sets that are specifically made for mixing and spraying coatings and these are equipped with; a membrane pump, mixing barrel with rudder and hose reel.
