These units were quite an innovation at the time. They were the very first units to incorporate a top load washer with a dryer on top built as a one piece unit. They were only 24" wide and worked quite well. They did not hold up well in service however. The washer had some problems with the clutch assembly that was used to drive the main unit, it wore out after a lot of use and had to be replaced which was no easy task. It did have one rollermatic roller in the operation too. The dryer had bakelite inside where the drum coasted along and was broken easily where the lint filter was and other places. Things could easily get caught and break the bakelite too. It was a very good idea and later on was copied by other companies and improved on. The agitub washer mech. washed fairly well, but the timer could have been extended longer for the wash and spin cycles and I think it would have done a better job. The units that ran on 220/240 dried clothes about the same as a typical dryer. The 110/120 units would take a long time to dry and you could not wash and dry at the same time. Nifty little units though. Frigidaire made them as separate units too, independent of each other as space saver sets. It just goes back to design and what was used to manufacture them could have been better.
