My wife, Lena, uses her 886 Royal as the "daily driver" around our house. I have frequently used the Hoover 28 or 82 Constellation upstairs, and used my Westinghouse Cannister or Filter Queen 350 in the basement. My 1070 Convertible or 858 Constellation have often accompanied me to the museum where I volunteer for cleaning in the display rooms. My Electro-Hygiene 701 tank and 903 upright have been used for cleaning out the car or truck (with attachments borrowed from the 966 tank or the wife's Royal!), although a Shop-vac (which I don't consider to be part of my collection) is used for general cleaning in the garage. Once the bag is fixed or replaced on my Hoover 29 and I get a good hose and attachments for my Luxes, I'll put them into the rotation also, so basically, if it runs, it gets used.
