Hi Susan, you have all your options for a new power kit for your Star system because you have standard wall ports for the vacuum hose. If you go with an Electric Kit (such as Stealth) be sure to buy the kit with the "8ft cord" that comes out the wall end of the hose and plugs into a nearby electrical outlet. The wires are then hidden in the lightweight hose for the 30 or 35-feet. You can start here www.builtinvacuum.com/kits.html
and let us know if you need more help. By the way, Electric Kits are THE best for any carpeting and of course work on all hard floors too.
