Vintage IMCO set. Appears to have been made for Barbie sized dolls. Probably from late 70s or early 80s. You can plug the washer and vacuum into the dryer. It’s powered by batteries, but because of age I do not recommend trying this the wiring is very old and looks like it has some problems. The cord on the vacuum has been replaced. From what I remember the washer never worked (it was a hand me down). The back doesn’t stay on well, but could easily be glued (I am not doing so because it’s easier to ship as is.
