The PondoVac 4 uses two chambers that alternate filling and emptying for continuous suction. It has a 1700W motor and a maximum suction depth of 2.4m.
The vacuum removes pond sludge and dirty water. A transparent suction section lets you see material passing through the hose, while the supplied hose and nozzle attachments reach different areas during cleaning.
