Unit Always On
Our last Central unit would start, automatically, upon inserting the hose in one of the outlets.
Our EF-1540 needs to be turned on at the unit, but it runs continually, until you manually shut it off.
I, as you can see, am no tecchie, and there is probably a simple explanation. However, please do not tell me that I have to turn the unit on at the base, vacuum, then return to the base to switch it off.
