A filter, separator and seal arrangement is disclosed for a wet and dry hand held vacuum cleaner. A cup-shaped filter is provided which is elongated to provide a large area for enhancing sustained air performance of the cleaner with the filter being disposed within a liquid separator so as to be generally coextensive therewith. A connection arrangement is also provided between the filter and separator so as to provide an air tight and liquid tight connection therebetween but which is also easily separable to facilitate cleaning of the two devices.
