Commissioning is extremely simple. You put the long tube top hole into it, then plugged many of the 4 tubes on the tube, and then follows the special Schlammdüse on the pipes. And at the bottom hole comes into the second tube, which has a small non-return valve. If you turn on the vacuum cleaner sucks the teat 25 seconds dirt and water from the pond and collects it in the container. After this time, the vacuum cleaner turns off and the lack of vacuum ensures that opens the non-return valve and runs out of the content from the device. After another 25 seconds, the process repeats again and again from new. The Silt really promotes enough dirt from the pond. One has to be said that cleaning hereby considerably simpler than as before when you had half empty pumps the pond to want to clean it with his hands.
The processing is made entirely of high quality. But two things make (even if only a little) criticism. The nozzle is too narrow for heavily dirty ponds with the width from 0 to 10mm. She tears well but something they would say up to 20 mm have been set the suction power would have been much better. As a counter comparison we had then sucked times complete without the nozzle - and because the puck went off. What then came out of the second tube. That you really do not have in the pond. And the second point of criticism are the four pipes. You are probably stable but you get every time a stab in the heart when you put them in the dirt so they can be bent.
