A composition comprising perfluoro-2,2-paracyclophane dimer compound is disclosed. This collapsible ability will also permit compact storage, a cooperating accessory dustpan is provided which the collapsible cleaning implement is stored into. The water in the cavity is substantially prevented from exiting the cavity because of an annular wiper blade and a secondary sealing blade that substantially contact the riser assembly through the riser assembly’s reciprocal movement between retracted and elevated positions. In the case of overlapping material images that have been placed, control processing is performed so that a smaller one of them is placed on a larger one of them.
