Does anybody know if these two attachment setups use the same attachments? They look extremely similar, but I can't find enough information about them to really see.

Yes, they're interchangeable in 99% of applications. I have seen an occasional few combinations where the driveshaft in attachment or power head is too short or too long to work. This is very rare though.
Expand-It attachments are also interchangeable with the two you mentioned.
