A filter assembly has an inlet for supplying a fluid to be cleaned and an outlet for returning cleaned fluid. A cloth filter is disposed between the inlet and the outlet. The filter has a web of filter cloth wound on a supply roll and guided along an effective filter area to a takeup roll for receiving clogged filter web. A motor is connected to the takeup roll for rotating the takeup roll and for transporting the filter cloth forward across the effective filter area. A switching device is connected to selectively energize the motor and to index the filter cloth forward by an amount less than a length of the effective filter area.
