Sludge suction for sucking algae and sludge out of artificial ponds, swimming pools, sauna pools or for collecting water from the floor.

Operation. The equipment worked in a similar way to a vacuum cleaner - through the nozzle and suction pipe, the debris and algae were sucked into the body of the equipment together with the water. From the casing the dirty water is fed into an outlet pipe, from which the liquid must be discharged into the scrub (good fertiliser) or into a drain. The water and debris absorbed is not filtered or collected by the machine (as in the case of a vacuum cleaner), but rather pumped from the pond to the ditch or scrub.
