The filter is easily attached to the basin with suction cups. The special feature of the pickup concept is that you can simply remove the filter container along with the filter sponge from the top. The pump unit remains in the basin during this process. This is very convenient for cleaning or replacing the filter cartridge. The pump draws water in from the bottom and transports it upwards through the filter sponge. Here, the cleaned water is returned to the basin through the rotatable outlet nozzle.
