By switching from a multi-nozzle conveyer belt (10x10L / min) to a single 40L / min nozzle, you save 3.6m3 / hour, which is 75m3 / month.
This makes a considerable gain in resources and working hours per month.
If you need 2 passes with a multi-nozzle conveyer belt, you only need one with the Arm-Cleaner.
In addition, the arm-cleaner does not need electricity to operate.
