Actually, the model of the unit is not at all the defining point of the hose used. In fact, any hose can be used, even electric ones with a pigtail cord. The main thing to consider when getting a hose is the shape and diameter of the hole in the wall inlet, and the cleaning needs of your home. Use the hose page and the kit page to choose what you'd like. Having said that, Vacumaid/Astrovac did have some non standard inlets. Ones that where not round are no longer supported (you'd have to buy a basic hose and put the end of the old hose on it), and some standard round ones with the correct 1-1/2 inch diameter have a single trigger inside the inlet hole instead of the two found in most standard inlets. If you have one trigger, you can use any hose you'd like but the on/off switch to control the suction at the hose handle will not work. However, having a better hose is certainly a benefit despite the switch not working. The hoses have a nice handle and spin so that the hose doesn't get kinked as it unwinds itself when used. So instead of a Basic Hose you can get a Low Voltage Hose, or an Electric Hose in an electric hose kit such as Stealth or Ace.
