Abstract
An apparatus for cleaning porcelain workpieces such as cast dolls' heads has at least one work station having an opening in a workplate above a column communicating with that opening and provided with a support basket in which a filter bag is received. The suction duct communicates with the column below the filter bag and above a bottom plate to draw dust through said opening into the column for collection on the filter. The workplate can be separated from the column for replacement of the filter bag.
