-The robot is delivered with, and shall be used with, a [[:parts:nozzle_types|turbo-nozzle]], working with a flow of 16 litres/minute at a pressure of 180 to 220 bars. This flow is less then most operators use when they are washing today but the whole idea about using a robot is that time is not so important anymore. Best result with the robot is achieved when it’s allowed to clean the same space several times.
+The robot is delivered with, and shall be used with, a size 0.55 [[:parts:nozzle_types|turbo-nozzle]]. The high-pressure washer suppling water to the robot must be specified to work with a flow of 16-18 liters/minute at a pressure of 180 to 220 bars. The water pressure will drop slightly between the pressure washer outlet and the nozzle.

 ==== What kind of high-pressure washer? ====
 A high-pressure washer with too big pump will by-pass the extra water or in worst case constantly start and stop. The incoming water is never completely clean and this by-pass causes a big wear on pump and valves. Too small pump and you will not get the pressure required.

-Remember to use a **[[:parts:water_filter|water filter]]**  with the incoming water to the high-pressure washer (filter placed before the high-pressure washer). Water isn't always clean and the particles make wear on the high-pressure washer and the nozzle.
