The cleaner received a significant update on 27 April 2015, giving it several unlockable upgrade tiers and new abilities. Other changes include: the spring cleaner works on several other drops, notably several types of ranged ammunition; spring capacity was increased from 500 to 250,000; items that the cleaner fails to dismantle drop to the floor instead of being consumed; and base bonus experience awarded by metal armour, metal weapons, metal bars, bows and amulets was significantly reduced. The spring cleaner was a possible prize from the 2016 Christmas Advent Calendar.
