This works on Electrolux Guardian canister vacuum cleaners. This one is in very good condition showing little evidence of use. It is clean and works fine except the headlight bulb is burned out. It has a switch on the user's right side that may be used to turn the brush roll off or on. This has the larger diameter hose connection tube and widely spaced electrical contact pins used on some later Electrolux models. Use this with the later style plastic wand sections.On Jul-01-11 at 18:17:26 PDT, seller added the following information: The output tube outside diameter on this measures approx. 1-9/16th inch.
