There are two options and one is only while supplies remain and I don't have any in the US.
The 9020.140 foam extractor is one option, this just blows the foam into a container, but, it will have to be possible to have the drain above the wall of the sump.
The 9015.140 is essentially two of the stock cups hand cut and fused together into one double size cup. This one is not made any more, but some supply remains. It can be made to order but given the hand labor and high cost we had planned to phase it out.
