This is one of the new type of automatic washing machines which incorporated full wash, rinsing and spin cycles and was extremely succesful in the 1960s. The Hoover 'Keymatic' featured a novel means of programming the machine by using the 'keycard' to select the wash programme. This model 3224 was introduced in 1961.
