The pump ∀ draws in the pond water via the suction unit ! and pumps it via the motive water hose ♣ through the nozzle hous- ing ∃ into the filter trough %. The jet of motive water streaming through the nozzle housing ∃ creates a vacuum in the dirty water hose &.

The dirty water is sucked up with the adapter nozzles / and pumped via the dirty water hose & and nozzle housing ∃ onto the filter sieves ) and collecting basket ( or collecting bag α.

The dirt is then filtered out of the water. (The cleaned water is not drinking water.)

The cleaned water is returned directly to the pond so that you do not loose any pond water. The biological balance of the pond is therefore maintained.

The slow suction speed not only ensures optimum cleaning results, but also ensures that flora and fauna in the pond remain unharmed, and prevents stones and plants from being drawn into the Silt Remover by accident.

The water that is returned to the pond contains (biologically active) floating particles. The cloudy appearance of your pond caused by these particles may last for several days.

If you accidentally suck up small creatures into the Pond Silt Remover (e.g. water snails, beetles) you can remove them from the open collecting basket ( and return them to the pond.

You can then dispose of the dirt and silt on your compost heap or with other garden refuse.
