Model 285 Electro-Hygiene
Although Royals were built with a revolving brush since the late 30's, Electro-Hygiene didn't have one until the 285 was introduced in 1955. The reason for this was they didn't know what to do with the crystal chamber. Then someone got the idea of making a crystal chamber that would snap on in place of the front cover, and EH could now have a revolving brush! This is one of the early 285's with the shake out bag and rubber handle grip, and is all original except for the cord and the brushroll.
