A pipeline cleaning arrangement that includes a cleaning pig with guide units at each end. A tow cable, via a cone, pulls the pig assembly in a forward direction. The tow cable then pulls the cone in a rearward direction. The pig is configured with two cleaning portions that separate in the forward direction to avoid debris collection and abut in the rearwards direction to collect pipeline debris and carry this to the entry point for removal via a suction tube.
