As mentioned in the other reviews, the assembly is somewhat tricky due to the rather suboptimal instructions. In use, the jet is very practical but, I've used it to my house to clean facade. It is actually up to 4 meters, but you can then save the standard, small nozzle use other essays since the tube for easy too thin. If one uses only two levels (about 3 feet) you can easily set up even the rotary nozzle.
