The ARF-1 removes the need for filter socks. Water is fed into the internal chamber via the aquarium systems drain, and through the filter roll. When the water level rises in the chamber due to filter clogging the water level switch triggers the motor to wind on the filter roll to a new fresh piece. The water level will then drop repeating the process.
